Posterolateral approach for tibial pilon fractures: a report of two cases

Open reduction and internal fixation (ORIF) of displaced tibial pilon fractures can lead to a high percentage of good and excellent functional results, but has also been associated with a meaningful incidence of wound breakdown and infection. The use of the posterolateral approach to the distal tibia for ORIF of tibial pilon fractures is presented. This may be used instead of the standard anteromedial incision in certain fracture configurations. The flexor hallucis longus muscle coverage overlying the plate fixation of the tibia and ability to fix both the tibia and fibula through the same incision may decrease the risk of deep infection and wound complications in these injuries frequently associated with marked soft tissue trauma.

Tibial pilon fractures: a comparison of treatment methods

OBJECTIVE: This retrospective review of surgically treated distal tibia fractures was undertaken to determine whether treatment with open reduction and internal fixation (ORIF) was more efficacious in achieving fracture union than one of two external fixation methods. METHODS: Of the 60 study patients with pilon fractures, 21 patients were treated with an ankle-spanning half-pin external fixator, 15 patients with a single-ring hybrid external fixator, and 24 patients with ORIF. The severity of injuries was similar across groups. RESULTS: There was no significant difference in complication rates between groups, although two below-knee amputations were required in the ORIF group. A greater (p = 0.03) number of malunions occurred in the fractures treated with external fixation when compared with those treated with ORIF. Fractures in the external fixator groups showed this significant tendency to lose their initial adequate reduction, independent of bone grafting or fibula fixation. There was no significant difference between groups in the need for bone grafting. There was a trend for patients treated with a single ring hybrid frame to require late bone grafting for metaphyseal-diaphyseal nonunion. CONCLUSION: External fixation offers advantages in the treatment of the soft-tissue injury associated with pilon fractures, but malunion continues to be a problem with this method of fixation.     

Reconstruction of distal tibia fractures using a posterolateral approach and a blade plate

OBJECTIVE: The aim of this article is to report a technique for the management of distal tibia fractures with significant anteromedial soft-tissue injury. The patients were initially treated with a spanning external fixator, open reduction and internal fixation (ORIF) of the fibula at the discretion of the surgeon, and soft-tissue management or flap coverage. ORIF of the tibia was performed on a staged basis, using a 90-degree cannulated blade plate and autogenous iliac crest bone graft through a posterolateral approach. DESIGN: Retrospective analysis of a consecutive series of patients. SETTING: Two academic level-1 trauma centers. PATIENTS: Fifteen patients with 15 distal tibia fractures (13 open fractures), Orthopedic Trauma Association (OTA) type 43A3 and 43C1, were definitively treated and followed to union between July 2000 and July 2004. Five patients were referred from outside sources after initial stabilization. INTERVENTION: Initial stabilization in an external fixator and management of the open fracture and soft tissue. Staged ORIF of the tibia with bone graft was performed through a posterolateral approach when the soft tissues allowed. OUTCOME MEASUREMENTS: Radiographic union, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, and complications. RESULTS: All 15 fractures were followed to union. Average time to union was 20 (12 to 47) weeks from the time of fixation with blade plate and bone grafting. (AOFAS) ankle-hindfoot score was used to measure outcome. The average score was 81 (60 to 97) out of a possible 100. There were no deep infections. There was one nonunion; the fracture united after revision with a locked plate and bone graft. The average length of follow-up was 14 months (4 to 37). CONCLUSIONS: The staged treatment of high-energy distal tibia fractures with soft-tissue injury can lead to good outcomes and consistent bone union. Our results were obtained by the combination of the posterolateral approach, careful soft-tissue management, and stable internal fixation.     

Midline posterior approach to the ankle and hindfoot

BACKGROUND: The posterior approach to the ankle and hindfoot can be used for fixation of fractures, fusions, or osteotomies and is especially useful in patients with poor soft tissue anteriorly, medially, or laterally. However, a high rate of wound complications has been reported with standard posterolateral and posteromedial approaches. Because of local wound problems with the standard approaches, we have used a midline posterior approach and a longitudinal midline splitting of the Achilles tendon. This approach provides excellent exposure while minimizing wound healing complications. This approach provides dissection between angiosomes, which should optimize preservation of the blood supply to the skin flaps. METHODS: We retrospectively evaluated wound healing in 33 consecutive patients who had surgery using the modified midline posterior approach. The mean age of the patients was 48 (range 16 to 83) years. The mean followup was 24 (range 12 to 73) months. Surgical procedures included ankle and pantalar arthrodeses (primary and revision), talectomies with tibiocalcaneal arthrodesis, repairs of fracture nonunions, reconstruction of a chronic Achilles rupture, and hardware removal with multiple debridements of chronic osteomyelitis. RESULTS: There were no instances of skin flap necrosis. One patient with diabetic neuropathic arthropathy developed a small superficial wound eschar that healed with dressing changes alone. Four patients developed deep infections; two of these had a history of deep infection and the other two had significant comorbidities. CONCLUSIONS: The modified midline posterior approach to the distal tibia, ankle, and hindfoot has a low primary wound complication rate without sacrificing exposure. This approach can be used for any procedure requiring posterior access to the distal tibia, ankle joint, or subtalar joint.     

Minimally invasive osteosynthesis of distal tibial fractures using anterolateral locking plate: Evaluation of results and complications

Purpose: Soft tissue healing is of paramount importance in distal tibial fractures for a successful outcome. There is an increasing trend of using anterolateral plate due to an adequate soft tissue cover on anterolateral distal tibia. The aim of this study was to evaluate the results and complications of minimally invasive anterolateral locking plate in distal tibial fractures. Methods: This is a retrospective study of 42 patients with distal tibial fractures treated with minimally invasive anterolateral tibial plating. This study evaluates the bone and soft tissue healing along with emphasis on complications related to bone and soft tissue healing. Results: Full weight bearing was allowed in mean time period of 4.95 months (3-12 months). A major local complication of a wound which required revision surgery was seen in one case. Minor complications were identified in 9 cases which comprised 4 cases of marginal necrosis of the surgical wound, 1 case of superficial infection, 1 case of sensory disturbance over the anterolateral foot, 1 case of muscle hernia and 2 cases of delayed union. Mean distance between the posterolateral and anterolateral incision was 5.7 cm (4.5-8 cm). Conclusion: The minimally invasive distal tibial fixation with anterolateral plating is a safe method of stabilization. Distance between anterolateral and posterolateral incision can be placed less than 7 cm apart depending on fracture pattern with proper surgical timing and technique.     

Treatment of distal tibia fractures without articular involvement: a systematic review of 1125 fractures

BACKGROUND: The management of unstable distal tibia fractures remains challenging. The mechanism of injury and the prognosis of these fractures are different from pilon fractures, but their proximity to the ankle makes the surgical treatment more complicated than the treatment tibial midshaft fractures. A variety of treatment methods have been suggested for these injuries, including nonoperative treatment, external fixation, intramedullary nailing, and plate fixation. However, each of these treatment options is associated with certain challenges. Nonoperative treatment may be complicated by loss of reduction and subsequent malunion. Similarly, external fixation of distal tibia fractures may result in insufficient reduction, malunion, and pin tract infection. Intramedullary nailing can be considered the "gold standard" for the treatment of tibial midshaft fractures, but there are concerns about their use in distal tibia fractures. This is because of technical difficulties with distal nail fixation, the risk of nail propagation into the ankle joint, and the discrepancy between the diaphyseal and metaphyseal diameter of the intramedullary canal. Open reduction and internal plate fixation results in extensive soft tissue dissection and may be associated with wound complications and infections. The optimal treatment of unstable distal tibia without articular involvement remains controversial. OBJECTIVES: This study was designed to review the outcomes of different treatment methods for extra-articular distal tibia fractures. The English literature was systematically reviewed and the rates of malunion, nonunion, infection, fixation failure, and secondary surgical procedures were extracted.     

A two-choice strategy through a medial tibial approach for the treatment of pilon fractures with posterior or anterior fragmentation

Objective： The anterolateral approach to the tibia has been popularized for the management of tibial pilon fractures. For complex fracture patterns a com- bined anterolateral/anteromedial approach is suitable but a high rate of complication has been reported. In our retro- spective study a two-choice strategy adopting a medial tibial approach was proposed for the treatment of pilon fractures with anterior or posterior fragmentation. Methods： Based on an anatomic study oftibial pilon fractures, we retrospectively analyzed the fractures with primary posterior, posterior-lateral or anterior, anterior-lat- eral （Tillaux-Chaput） involvement of the distal tibia. This retrospective study consisted of 18 patients with a closed tibial plafond fracture. The inclusion criteria were： （1） pre- sence of an anterior/anterolateral type fragment or a poste- rior （Volkmann） type fragment involving 〉25% of the articu- lar surface, （2） a minimum follow-up of 12 months, （3） a fibula fracture associated with a medial colunm fracture of the distal tibia, and （4） soft tissue conditions at the time of opera- tion that did not compromise the choice of surgical access （Tscheme classification for closed fractures： grade 0 and grade 1）. Tibial plafond fractures were classified into two groups： one presenting anterior and the other with poste- rior rim （Volkmann） fragments. Results： Most patients achieved a good clinical re- covery in terms of range of motion and Olerud-Molander scale scores. Only three patients presented a grade 2 os- teoarthritis at the 12 month follow-up. Conclusion： Our two-choice strategy highlights con- cepts which have been previously debated and described in the literature. But a new extended protocol for surgical approach to the distal tibia, including more fracture pat- terns and their association should be further investigated.     

Open reduction and internal fixation of tibial pilon fractures using a lateral approach

OBJECTIVES: To assess the wound complications and reductions achieved in a cohort of patients with pilon fractures who were treated using a novel lateral approach. DESIGN: Retrospective review. SETTING: Two level 1 trauma centers affiliated with academic institutions. PATIENTS/METHODS: All 44 fractures (in 43 patients) treated by the senior authors with open reduction and internal fixation (ORIF) using the lateral approach as the primary approach were included. INTERVENTION: Data regarding medical comorbidities, mechanism of injury, soft-tissue injury sustained during the injury, treatment, wound healing, and secondary surgeries were recorded. Fractures were classified using the AO/OTA system with most being type C3. Eighteen fractures were open injuries (10 type 3). Fracture reductions were scored using the criteria of Teeny and Wiss. MAIN OUTCOME MEASUREMENTS: Quality of articular reduction and soft-tissue healing. RESULTS: An anatomic or good fracture reduction was achieved in 41 fractures (93%), and a fair reduction was obtained in 3 fractures. Two patients were successfully treated for deep infection (4.5%), and 2 patients developed a wound dehiscence (4.5%). There were no amputations. Twelve patients underwent secondary surgeries (27%). Five of these were for symptomatic screw removal (related to the fibular hardware in all cases), and the sixth was for planned removal of a syndesmotic-type screw (13.6%). Four were for nonunion, representing 9% of all cases. The remaining secondary surgeries (2 cases) were performed for infection. Overall, 13.6% of patients underwent a secondary surgical procedure to address nonunion or infection. CONCLUSIONS: When applied in a staged fashion, the lateral surgical approach for pilon fractures provides excellent protection of the soft-tissue envelopes by creating thick flaps while allowing excellent visualization for reconstruction of the anterior and lateral distal tibia.     

Open distal tibial shaft fractures: a retrospective comparison of medial plate versus nail fixation

Purpose

Studies comparing open reduction internal fixation (ORIF) vs. intramedullary nailing (IMN) for distal tibia shaft fractures focus upon closed injuries containing small patient series with open fractures. As such, complication rates for open fractures are unknown. To characterize complications associated with ORIF vs. IMN, we compared complications based on surgical approach in a large patient series of open distal tibia shaft fractures.

Methods

Through retrospective analysis at an urban level I trauma center, 180 IMN and 36 ORIF patients with open distal tibia fractures from 2002 to 2012 were evaluated. Patient charts were reviewed to identify patient demographics, fracture grade (G), patient comorbidities, and postoperative complications including nonunion, malunion, infection, hardware-related pain, and wound dehiscence. Fisher’s exact tests compared complications between ORIF and IMN groups. Multivariate regression identified risk factors with statistical significance for the development of a postoperative complication.

Results

One hundred and eighty IMN (G1 22, G2 79, and G3 79) and 36 ORIF (G1 10, G2 16, and G3 10) patients were included for analysis. ORIF patients had a higher rate of nonunion (25.0 %, n = 9) compared with IMN patients (10.6 %, n = 20, p = 0.03). No additional complication had a significant statistical difference between groups. Multivariable analysis shows only surgical method influenced the development of complications: ORIF patients had 2.52 greater odds of developing complications compared with IMN patients (95 % CI 1.05–6.02; p = 0.04).

Conclusions

ORIF leads to higher rates of nonunion and significantly increases the odds of developing a complication compared with IMN for open distal tibia fractures. This is the first study investigating complication rates based on surgical approach in a large cohort of patients with exclusively open distal tibia fractures.

     

A staged protocol for soft tissue management in the treatment of complex pilon fractures

OBJECTIVE: To determine whether open reduction and internal fixation of intra-articular pilon fractures using a staged treatment protocol results in minimal surgical wound complications. DESIGN: Retrospective. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: Between January 1991 and December 1996, 226 pilon fractures (AO types 43A-C) were treated, of which 108 were AO type 43C. Fifty-six fractures were included in a retrospective analysis of a treatment protocol. Injuries were divided into Group I, thirty-four closed fractures, and Group II, twenty-two open fractures (three Gustilo Type 1, six Type II, eight Type IIIA, and five Type IIIB). METHODS: The protocol consisted of immediate (within twenty-four hours) open reduction and internal fixation of the fibula when fractured, using a one-third tubular or 3.5-millimeter dynamic compression plate and application of an external fixator spanning the ankle joint. Patients with isolated injuries were discharged after initial stabilization and readmitted for the definitive reconstruction. Polytrauma patients remained hospitalized and were observed. Formal open reconstruction of the articular surface by plating was performed when soft tissue swelling had subsided. Complications were defined as wound problems requiring hospitalization. All affected limbs were then evaluated via chart and radiograph review, patient interviews, and physical examination until surgical wound healing was complete, for a minimum of twelve months. RESULTS: Group 1 (closed pilon): Follow-up was possible in twenty-nine out of thirty fractures (97 percent). Average time from external fixation to open reduction was 12.7 days. All wounds healed. None exhibited wound dehiscence or full-thickness tissue necrosis requiring secondary soft tissue coverage postoperatively. Seventeen percent (five out of twenty-nine patients) had partial-thickness skin necrosis. All were treated with local wound care and oral antibiotics and healed uneventfully. There was one late complication (3.4 percent), a chronic draining sinus secondary to osteomyelitis, which resolved after fracture healing and metal removal. Group II (open pilon): Follow-up was possible in seventeen patients with nineteen fractures (86 percent). Average time from external fixation to formal reconstruction was fourteen days (range 4 to 31 days). By definition, all Gustilo Type IIIB fractures required flap coverage for the injury. Two patients experienced partial-thickness wound necrosis. These were treated with local wound care and antibiotics. All surgical wounds healed. There were two complications (10.5 percent), both deep infections. One Type I open fracture developed wound dehiscence and osteomyelitis requiring multiple debridements, intravenous antibiotics, subsequent removal of hardware, and re-application of an external fixator to cure the infection. One Type IIIA open fracture of the distal tibia and calcaneus developed osteomyelitis and required a below-knee amputation. CONCLUSION: Based on our data, it appears that the historically high rates of infection associated with open reduction and internal fixation of pilon fractures may be due to attempts at immediate fixation through swollen, compromised soft tissues. When a staged procedure is performed with initial restoration of fibula length and tibial external fixation, soft tissue stabilization is possible. Once soft tissue swelling has significantly diminished, anatomic reduction and internal fixation can then be performed semi-electively with only minimal wound problems. This is evidenced by the lack of skin grafts, rotation flaps, or free tissue transfers in our series. This technique appears to be effective in closed and open fractures alike.     

Early outcome of hybrid external fixation for fracture of the distal tibia

OBJECTIVE: To evaluate the early results of treatment when using hybrid external fixation for fractures of the tibial plafond. DESIGN: Retrospective review of patients treated according to protocol. Patients treated with the hybrid fixator were compared with patients treated with open reduction and internal fixation. SETTING: Orthopaedic trauma service of a Level I trauma center, with a single surgeon directing care. PATIENTS/PARTICIPANTS: All patients with fractures of the distal tibia during a five-year period (n = 63) were treated according to protocol, with specific criteria determining method of treatment. Eleven patients were lost to follow-up, and three additional patients were not reviewed for other reasons. Follow-up period averaged twenty months. INTERVENTION: Fracture stabilization was accomplished with the use of a hybrid external fixator (n = 34) or with internal fixation (n = 27), as determined by patient or fracture criteria. Two patients did not receive planned treatment. MAIN OUTCOME MEASUREMENTS: Range of motion, clinical ankle score, and incidence of complications. RESULTS: Patients treated with hybrid fixation had lower clinical scores, slower return to function, a higher rate of complications, more nonunions and malunions, and more infections. CONCLUSIONS: Due to differences in patient populations, the superiority of either treatment method is uncertain; however, hybrid fixation did not seem to solve the problems inherent in severe pilon fractures. The sanguine results reported in the literature did not hold true in this group.

Langzeitergebnisse nach operativer Versorgung von Pilon-tibial-Frakturen Eine retrospektive Untersuchung

Background: While Pilon fractures of the tibia have been treated for decades by primary open reduction and internal fixation by plate osteosynthesis, during the last 10 years differential treatment was developped: After primary open reduction nowadays patients are treated with (according to type of fracture and tissue damage). As well as primary open reduction and internal fixation a two-step treatment (primary external fixator and delayed ORIF) or consolidation by external fixator combined with minimal invasive osteosynthesis (cannulated screws and K-wires) has been implemented. Furthermore, the significance of primary bone grafting in comminuted fractures to prevent aseptic pseudarthrosis has been acknowledged. Methods: Of 151 patients with 160 pilon fractures treated from January 1979 to May 1995, 107 patients (113 fractures) were evaluated. Only the results of C2 and C3 fractures could be compared, as only in these groups were all three types of treatment used. Results: Over 75% of the treated fractures were closed fractures, most of them being fractures with a soft tissue damage grade 2 of the Oestern and Tscherne classification. In the open fractures we found mainly grade 3 fractures according to the Gustilo and Anderson classification. In 54.9% of all pilon tibial fractures we observed an uncomplicated course of healing. Early complications (25.7%) were mainly soft tissue infections, whereas we found pseudarthrosis to be the most frequent late complication. Highest infection rate (55.5%) was in the two-step treatment group (primary external fixator and delayed ORIF) and lowest in the primary internal stabilization group, although especially in the C2 and C3 fractures best clinical late results were obtained with the two-step procedure. Conclusion: The complication rate in the treatment of pilon fractures depends mainly on the type of fracture, the soft tissue damage and the type of treatment. The results of primary ORIF varied. In the case of low-grade soft tissue damage, good to excellent results were accomplished. In the case of higher-grade soft tissue damage, the problem of soft tissue coverage and reconstruction of the joint surface could be solved with good results by the two-step treatment. Herewith it is important to use limited open reduction of displaced fragments and fixation by cannulated screws and K-wires. We consider ORIF of the fibula necessary as stabilization of the second column of the ankle joint.     

Treatment of tibial nonunion with posterolateral bone grafting

ObjectivesPosterolateral bone grafting to treat nonunions of the distal two-thirds of the tibia avoids the often traumatized and more tenuous anterior soft-tissue envelope. Few modern reports of its effectiveness are available. We assessed whether posterolateral bone grafting leads to high union and low complication rates.MethodsWe conducted a retrospective review at a Level I trauma center. Our study group was 59 patients with distal two-thirds tibial fractures treated with posterolateral bone grafting. Patients included those with history of deep surgical site infection (SSI) before bone grafting (n = 17), established nonunions (n = 42), and impending nonunions associated with open fractures and bone gaps (n = 17). All patients were followed for a minimum of 12 months unless they achieved union before that time point. Our primary outcome measurement was fracture union. Secondary outcome measurements were any complication associated with the approach and infection requiring return to the operating room.ResultsFracture union was achieved in 44 (75%) of 59 patients without further intervention. The mean interval to union was 9.9 months (range, 3–22). Of 11 infected nonunions treated, nine progressed to union. Seventeen of 23 patients with defects >2 cm, including defects up to 5.4 cm without infection, were successfully treated. Two patients who underwent grafting at least 10 years after initial injury achieved union. No complications were associated with the approach (specifically, no wound breakdown, vascular injury, or tendon injury). Fourteen percent of patients experienced SSI after bone grafting. Seven of eight deep SSI occurred in patients with previous infection or positive intraoperative cultures. Only one (3%) of 36 patients without infection pre- or intraoperatively experienced SSI.ConclusionsEven in this relatively difficult patient cohort that included large bone gaps and history of infection, union was achieved at a relatively high rate with posterolateral bone graft. The approach seems to be safe, considering no known complications specifically associated with the approach occurred, and seems to reduce the risk of SSI in the absence of previous infection.     

Outcomes of fixation for periprosthetic tibia fractures around and below total knee arthroplasty

IntroductionThe incidence of periprosthetic fractures after total knee arthroplasty (TKA) is rising due to an increasing number of TKAs performed annually and the growing elderly population. Like periprosthetic fractures of the distal femur, periprosthetic tibia fractures are primarily treated with operative fixation; however, there is limited scientific literature that has reported outcomes of periprosthetic tibia fractures treated with modern plating techniques. To our knowledge, this is the largest series of non-intraoperative periprosthetic tibia fractures treated with open reduction internal fixation (ORIF) ever reported.MethodsRetrospective chart review of 4557 operatively treated tibia fractures with ORIF over a 16-year period at two Level 1 Trauma Centers.Results38 patients with an average follow-up of 15.3 months (range 3–24) were identified. 11 (28.9%) fractures were in the proximal tibia (four with extension into the plateau (Felix 1A) and seven adjacent to the tibial stem (Felix 2A)), six (15.8%) in the midshaft/diaphysis (Felix 3A), and 21 (55.3%) in the distal 1/3rd (metaphysis, Felix 3A). 76.3% (29/38) of fractures united by 6 months following the index procedure, leaving 9 nonunions. The overall re-operation rate was 31.6% (12/38). There were no significant differences in rates of union (p = 1.00), reoperation (p = 0.66), superficial infection (p = 0.66), or deep infection (p = 0.31) in patients treated with single versus dual plating.ConclusionPeriprosthetic tibia fractures are difficult to treat and have a high risk of nonunion and reoperation even with modern plating techniques. Most patients can be treated to union with operative fixation and do not require revision arthroplasty, if the components are stable initially. We recommend dual plating for fractures in the proximal third, and either single plating or nailing for fractures in the middle and distal thirds depending on bone quality, implant positioning, and fracture morphology.     

A Pilon Fracture With Fibular Head Dislocation Treated With the Use of 3D Preoperative Planning: A Case Report and Literature Review

Pilon fractures with intact fibula have been associated with low-energy trauma. However, the compression force onto the ankle joint can damage the tibiofibular linkage as in a Maisonneuve fracture. Herein, we describe a case of a patient who had a pilon fracture (AO type 43 C3.2) without a fibular fracture. Three-dimensional preoperative simulation by reduction with the surface registration technique was performed as the fibular length was intact and there was no reference for the tibial length. The preoperative simulation revealed superior fibular head dislocation and shortening of the distal tibia. After emergency external fixation on the day of arrival, a 2-staged surgery was performed. During the first operation, the fibular head was reduced and the tibial posterolateral fragment was fixed to restore the tibia length. During the second operation, medial and anterolateral fragments were fixed in order to reduce joint surface of the distal tibia. In general, proximal fibular head fractures are easily overlooked. In the case of pilon fractures with severe length shortening of the tibia without a fibular fracture, a proximal tibiofibular injury should be suspected.     

Distal tibia fractures: management and complications of 101 cases

Distal tibia fractures are complex injuries with a high complication rate. In this retrospective and multicentre study we attempted to detail complications and outcomes of this type of injury in order to determine predictive factors of poor results. Between 2002 and 2004, 104 patients were admitted for 105 distal tibia fractures. One hundred patients (101 fractures) were reviewed with an average follow-up of 19 months (range, 12–46). Internal fixation, external fixation, limited internal fixation (K-wires or screws), intramedullary nailing and conservative treatment were used. Outcome parameters included occurrence of complications, radiographic analysis, evaluation of the American Orthopaedic Foot and Ankle Society (AOFAS) ankle score and measures of the ankle range of motion. The average functional score was 76 points (range, 30–100 points), and complications occurred in 30 patients. Predictive factors of poor results were fracture severity, complications, malunion and the use of external fixation. We believe that external fixation must be reserved for trauma with severe skin injury, as a temporary solution in a two-staged protocol. For other cases, we recommend ORIF with early mobilisation.     

Results and outcomes after operative treatment of high-energy tibial plafond fractures

BACKGROUND: The purposes of this study were to evaluate the clinical and radiographic results and the functional outcomes after operative treatment of tibial plafond fractures treated with internal or external fixation. METHODS: A retrospective review identified 76 patients with 79 fractures (OTA 43-B or 43-C) of the tibial plafond. Their average age was 45 years. Twenty-one fractures (27%) were open, and 43 (54%) were type 43-C3. Five were type 43-B1, four were 43-B2, two were 43-B3, 15 were 43-C1, and 10 were 43-C2. Patients were treated with open reduction and internal fixation (ORIF) (n = 63) or limited open articular reduction and wire ring external fixation (EF) (n = 16). Tibial fixation was performed at a mean of 7.6 days after injury, with staged reconstruction in 56 fractures (71%). Bone graft was used initially in 32 fractures (41%). Early and late complications, secondary procedures, and radiographic evidence of post-traumatic arthritis were evaluated. Foot Function Index (FFI) and Musculoskeletal Function Assessment (MFA) questionnaires were administered. RESULTS: Seventy-nine fractures were followed clinically and radiographically for a mean of 26 (range 24 to 38) months, and 33 patients completed outcomes questionnaires at a mean of 98 months after surgery. Early complications included two superficial wound problems and three deep infections. Late complications included two nonunions and four malunions. Thirty-one fractures (39%) developed post-traumatic arthritis. Complications occurred after six of 21 open fractures and after 11 of 43 type C3 fractures (p = 0.007). Patients treated with EF more frequently had type C3 fractures (88% versus 46%, p = 0.004) compared with patients treated with ORIF. The EF patients developed more complications (six of 16, p = 0.007) and post-traumatic arthritis (11 of 16, p = 0.01) when compared with ORIF. Patients treated with EF (88% were type C3 fractures) had lower FFI and MFA scores. The greatest impairment in outcome was noted after type C3 fractures, regardless of the method of treatment. CONCLUSIONS: Tibial plafond fractures are difficult to manage and may have serious complications. We identified more complications, more secondary procedures, and worse outcomes in patients with articular and metaphyseal comminution (type C3). ORIF was associated with fewer complications and less post-traumatic arthritis when compared to EF, possibly reflecting a selection bias for open injuries and more severely comminuted fractures to be managed with EF. ORIF with appropriate soft tissue handling resulted in acceptable results in most patients. Severely damaged soft tissues and highly comminuted C3 fractures may be safely treated with EF. Loss of function and progression to post-traumatic arthritis are common after tibial plafond fractures. Assessment of long-term results and the efficacy of additional reconstructive procedures will refine the treatment algorithms for these fractures.     

Vacuum-assisted-closure-Therapie

This article reports the case of a 23-year-old woman who sustained severe soft tissue injuries with open fractures of the left distal femur, the left proximal tibia, a subtotal amputation of the left foot with injuries to the anterior and posterior tibial artery due to a bomb blast. When the patient was transferred to our hospital 17 days after the trauma, all primarily closed wounds were severely infected. The fractures were treated by external fixateur and k-wire fixation. After debridement and initiation of negative pressure therapy the anterior tibial artery was reconstructed after 3 days and partial wound closure by a rectus abdominis muscle flap was achieved after 19 days. After almost total wound closure was accomplished open reduction internal fixation (ORIF) was performed for the distal femur fracture and a modification of the external fixateur for the tibial and foot fractures. The negative pressure therapy is an important component for treatment of complex soft tissue injuries and open fractures; however, it must be embedded in an interdisciplinary treatment plan with well-defined treatment goals.
