Diagnosis and treatment of combined intra-articular disorders in acute distal fibular fractures

BACKGROUND: Some patients have residual ankle pain and disability after the treatment of an ankle fracture, despite the fracture site being well aligned. We identified intra-articular disorders in distal fibular fractures and sought to clarify the results of their operative treatment. METHODS: This is a prospective, randomized study. Seventy-two patients with Weber type B distal fibular fractures were randomly treated with arthroscopy-assisted open reduction and internal fixation (AORIF) or with open reduction and internal fixation without arthroscopy (ORIF). In the AORIF group, the patients were followed for a mean duration of 3 years 4 months (range, 2 years 4 months-4 years 5 months). There were 27 male patients and 14 female patients. The mean age of the patients at the time of surgery was 36 years (range, 20-64 years). In the ORIF group, the patients were followed for a mean duration of 3 years 5 months (range, 2 years 7 months-4 years 5 months). There were 21 male patients and 10 female patients. The mean age of the patients at the time of surgery was 38 years (range, 20-58 years). We described intra-articular disorders in the AORIF group using ankle arthroscopy and compared their operative results with those of the ORIF group. RESULTS: Including duplication, the arthroscopic findings showed 30 cases with osteochondral lesions of the talar dome (73.2%) and 33 cases with tibiofibular syndesmosis disruptions (80.5%). Six cases (14.6%) had no combined disorders. The mean AOFAS score was 91.0 +/- 3.5 (range, 85-100) in the AORIF group, in contrast to 87.6 +/- 5.5 (range, 77-97) in the ORIF group (p = 0.0106). CONCLUSION: In the treatment of distal fibular fractures, precisely diagnosing and treating the combined intra-articular disorders is important for gaining satisfactory clinical results.     

Ankle fracture configuration following treatment with and without arthroscopic-assisted reduction and fixation

AIM: To report ankle fracture configurations and bone quality following arthroscopic-assisted reduction and internal-fixation(ARIF) or open reduction and internalfixation(ORIF). METHODS: The patients of ARIF(n = 16) or ORIF(n = 29) to treat unstable ankle fracture between 2006 and 2014 were reviewed retrospectively. Baseline data, including age, sex, type of injury, immediate postoperative fracture configuration(assessed on X-rays and graded by widest gap and largest step-off of any intraarticular site), bone quality [assessed with bone mineral density(BMD) testing] and arthritic changes on X-rays following surgical treatments were recorded for each group.RESULTS: Immediate-postoperative fracture configurations did not differ significantly between the ARIF and ORIF groups. There were anatomic alignments as 8(50%) and 8(27.6%) patients in ARIF and ORIF groups(P = 0.539) respectively. There were acceptable alignments as 12(75%) and 17(58.6%) patients in ARIF and ORIF groups(P = 0.341) respectively. The arthritic changes in follow-up period as at least 16 wk following the surgeries were shown as 6(75%) and 10(83.3%) patients in ARIF and ORIF groups(P = 0.300) respectively. Significantly more BMD tests were performed in patients aged 60 years(P 0.001), ARIF patients(P = 0.021), and female patients(P = 0.029). There was no significant difference in BMD test t scores between the two groups. CONCLUSION: Ankle fracture configurations following surgeries are similar between ARIF and ORIF groups, suggesting that ARIF is not superior to ORIF in treatment of unstable ankle fractures.

Operative costs associated with arthroscopic assisted open reduction and internal fixation of acute ankle fractures

BackgroundAnkle fractures are a common orthopedic injury that frequently involves associated cartilage lesions, soft tissue damage, and a significant inflammatory burden. Despite studies revealing intra-articular pathology in up to 79% of ankle fractures, only 1% of open reduction and internal fixation (ORIF) procedures undergo arthroscopic evaluation. The primary purpose of this study was to determine the cost effectiveness of ankle arthroscopy performed at time of ORIF for ankle fracture.MethodsAn IRB approved retrospective review of patients who sustained ankle fractures and underwent ORIF with and without concomitant arthroscopic surgery between 2015 and 2020 were investigated. Patient demographics, fracture characteristics, outcomes, and cost data were collected and analyzed.ResultsThere were 567 total ORIF and 28 ORIF and scope included for cost analysis purposes. Total surgical costs averaged $6,537.62 and $6,886.46 for the ORIF only and ORIF and scope procedures respectively. Total direct costs, including operating room time, for the same procedures were found to average $6,212.34 and $7,312.10 for the ORIF only and ORIF and scope procedures respectively. The cost difference between the ORIF only and with arthroscopy was not statistically significant (p = 0.1174). Twelve of the 28 arthroscopic patients (42.86%) had grade 3 or full thickness chondral lesions, and 11/28 (39.28%) arthroscopic patients were found to have grade 1–2 cartilage changes.ConclusionIn the acute treatment of ankle fractures, concurrent arthroscopic evaluation does not add a significant cost to the procedure and may result in improved short and long term benefits for the patient. With improved arthroscopic efficiency, the cost differential can be further reduced.LOEIV.     

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.     

Postoperative Reoperations and Complications in 32,307 Ankle Fractures With and Without Concurrent Ankle Arthroscopic Procedures in a 5-Year Period Based on a Large U.S. Healthcare Database

Residual symptoms often persist even after successful operative reduction and internal fixation (ORIF) of ankle fractures. Concurrent ankle arthroscopic procedures (CAAPs) have been proposed to improve clinical outcomes; however, a dearth of evidence is available supporting this practice. The purpose of the present study was to investigate the reoperation and complication rates after ORIF of ankle fractures with and without CAAPs. Reoperations and complications after ORIF of ankle fractures were identified using the PearlDiver database from January 2007 to December 2011. The CAAPs included bone marrow stimulation, debridement, synovectomy, and unspecified cartilage procedures. Reoperation procedures consisted of ankle fracture repeat fixation, arthroscopic procedures, osteochondral autograft transfers, and ankle arthrodesis. Of the 32,307 patients who underwent ankle fracture fixation, 248 received CAAP and 32,059 did not. No significant difference was found in the reoperation rate between the 2 groups (7.7% versus 8.6%; odds ratio 0.89; 95% confidence interval 0.55 to 1.42; p?=?.61). Of the 248 patients in the CAAP group, 19 (7.7%) underwent reoperation, of which 13 (68.4%) were arthroscopic debridement and 6 were either ankle refixation or osteochondral autograft transfer. For the non-CAAP group, 3021 reoperation procedures were performed, consisting of ankle refixation in 83.2%, arthroscopic procedures in 14.3%, and ankle arthrodesis in 2.5%. The complication rate in the non-CAAP group included wound dehiscence in 2.4%, wound surgery in 0.4%, deep vein thrombosis in 0.8%, and pulmonary embolism in 0.4%. No complications were detected in the CAAP group. Ankle fracture fixation with CAAPs did not increase the postoperative reoperation rate compared with ankle fracture fixation without CAAPs.     

Treatment of distal tibial fractures: plate versus nail

A study of 24 patients who sustained an extra-articular fracture of the distal third of the tibial shaft was performed to determine the effect of the type of treatment, open reduction and internal fixation (ORIF) or closed reduction and intramedullary (IM) nailing, on the occurrence of malalignment. All patients were treated in our clinic between 1993 and 2001 for a fracture in the distal third of the tibia. Twelve patients treated with ORIF were matched to 12 patients treated with IM nailing, with regard to gender, age decade, and the AO classification of the fracture. The group treated with IM nailing was assessed after a mean 6.0 years versus ORIF after a mean of 4.5 years. Two patients treated with ORIF versus six patients treated with IM nailing had a malalignment of the tibia. Furthermore, we found no difference with regard to time to union, non-union, hardware failure or deep infections between ORIF and IM nailing. Our results suggest that control of alignment is difficult with IM nailing of distal tibial fractures. For optimal alignment we advise considering the use of ORIF for closed and type I open extra-articular fractures in the distal third of the tibia.

Arthroscopic ankle arthrodesis after tibial pilon open reduction internal fixation

Ankle arthrodesis is an essential tool in the foot and ankle surgeon's armamentarium. Despite the evolving technology and ongoing research in ankle arthroplasty, arthrodesis continues to be a proven and safe option for the majority of patients with ankle arthritis refractory to conservative management. Here, the authors present their technique of an arthroscopic ankle arthrodesis specifically in the setting of a previous open-reduction internal fixation (ORIF) for a tibia plafond type fracture. They have found this to be a reliable technique to achieve a solid ankle arthrodesis while minimizing soft-tissue trauma and dissection in an already compromised soft-tissue envelope.     

Combined ipsilateral fractures of talus and calcaneus

INTRODUCTION: The purpose of this study was to evaluate the frequency of combined ipsilateral talar and calcaneal fractures, the fracture pattern in combination and the clinical outcome of the combined operative treatment. MATERIALS AND METHODS: Out of 950 patients with calcaneal fractures and 190 patients with talar fractures treated operatively between 1984 and 2003, 11 patients (1% of calcaneal and 6% of talar fractures) were identified with combined ipsilateral talar and calcaneal fractures. Closed reduction and external fixation was performed in one patient with a crush foot injury, and ORIF in all other patients and fractures. All patients underwent clinical and radiological evaluation after a minimum followup period of one year using the AOFAS-Hindfoot Score. RESULTS: Seven patients had central talar body and 4 patients talar neck fractures. Nine calcaneal fractures were extraarticular sustentaculum, as well as processus anterior fractures, and two were intraarticular fractures. Average followup was 6 (range, 1 to 12.5; median, 4.5) years. There were no perioperative complications related to ORIF. AOFAS-Hindfoot-Score averaged 78.6 (range, 50 to 100). The followup x-rays showed post-traumatic arthritis in the ankle joint in 3 patients and in the subtalar joint in five. AVN with peudarthorsis was present in one patient with an intraarticular calcaneal fracture. Patients with intraarticular calcaneal fractures presented with the worst functional results (AOFAS-Score, 50 and 64), none of these patients required a secondary ankle or subtalar fusion. All other patients had good and excellent functional outcome. CONCLUSION: Combined ipsilateral talar and calcaneal fractures are rare injuries. Extraarticular calcaneal fractures are more common in this injury pattern, while there was no preference for either talar neck or talar body fractures. Operative treatment with anatomic open reduction and internal fixation may result in favorable clinical outcome. Combined surgical approaches to the hindfoot did not result in increased morbidity.     

Distale Tibiafrakturen

Distal tibial fractures can be divided by mechanism into injuries caused by torsion trauma or by compression trauma. The latter ones are often associated with a complete destruction of the tibial joint surface, so-called tibial plafond fractures. Another group of fractures are the distal metaphyseal fractures of the tibia with only minimal involvement of the ankle as a result of low energy torsion trauma. Multiple factors can be held responsible for posttraumatic complications and poor outcome: malalignment, nonanatomic reduction of the joint surface or bone defects, and severe soft tissue injury. Therefore a sophisticated therapeutic regime of distal tibial fractures is necessary, which we present in detail in this article. In cases with only minor soft tissue injury a primary definitive open reduction internal fixation (ORIF) of the tibial fracture is possible. Fractures with severe soft tissue injury should be initially fixed with an external fixator. Definitive fixation and reconstruction should here be performed in subsequent operations. Early functional therapy can be attempted if fractures are reliably stabilized.     

Fracture of the tibia with additional injury of the ankle joint. A frequent and undervalued combination

Summary There are 2 types of a combined tibia fracture and ankle injury: in Type I the tibia fracture extends directly into the ankle joint, in Type II the tibia fracture goes along with a fracture of the fibula and disruption of the fibular-tibial syndesmosis. This type of fracture must be distinguished from a pilon tibiale fracture. The typical mechanism for this combined tibia and ankle injury is the indirect torsional trauma with pronation-eversion. From 1995 to 1997 188 patients with fractures of the tibia were treated by internal fixation in our Trauma Department. 27 of these patients (13.6 %) had a combined tibia and ankle injury. Most of the tibia fractures were located in the distal third, a spiral fracture (16 patients) or a comminuted fracture (6 patients), and another group extending directly into the ankle (5 patients). The ankle lesion was a distal fibular fracture (Weber Typ B + C) in 14 patients, a proximal fibular fracture (Type maisoneuve) in 6 patients, a postero-lateral fragment in 11 cases and a fracture of the medial melleolus in 10 cases. A disrupture of the anterior tibio-fibular syndesmosis was seen in 18 patients, 3 times as an isolated lesion of the ankle joint without fracture of the fibula. The osteosynthesis of the tibia fracture was performed with an unreamed tibia nail in 20 patients, with elastic-biologic plate fixation in 6 and with external fixation in 1 patient. The fibula fractures were stabilized by small fragment titaneum plates, the dorsolateral fragment and the medial malleolus were stabilized by lag-screws, the tibio-fibular ligament was sutured and, in a few cases only, held in place by a positioning screw. The outcome was controlled after 20,7 month according to the Phillip's Score (1996). We found not more than one pour results. It must be considered, that most of the combined injuries of the tibia and the ankle joint concerning 13,6 % of all tibia shaft fractures are usually not recognized and may result in an arthrosis of the ankle joint. The attention should be focused to the ankle joint in any spiral fractures of the distal tibia after indirect trauma, especially with a proximal fibular fracture or an intact fibula. Additional X-ray examination of the ankle joint is recommended during internal fixation of the tibia. Posttraumatic arthrosis of the ankle joint can be prevented by diagnosis and adequate anatomical reconstruction of the additional ankle joint injury.      

Tibial plateau fractures: compared outcomes between ARIF and ORIF

The purpose of this study is to compare arthroscopic assisted reduction internal fixation (ARIF) treatment with open reduction internal fixation (ORIF) treatment in patients with tibial plateau fractures. We studied 100 patients with tibial plateau fractures (54 men and 46 women) examined by X-rays and CT scans, divided into 2 groups. Group A with associated meniscus tear was treated by ARIF technique, while in group B ORIF technique was used. The follow-up period ranged from 12 to 116 months. The patients were evaluated both clinically and radiologically according to the Rasmussen and HSS (The Hospital for Special Surgery knee-rating) scores. In group A, the average Rasmussen clinical score is 27.62 ± 2.60 (range, 19–30), while in group B is 26.81 ± 2.65 (range, 21–30). HSS score in group A was 76.36 ± 14.19 (range, 38–91) as the average clinical result, while in group B was 73.12 ± 14.55 (range, 45–91). According to Rasmussen radiological results, the average score for group A was 16.56 ± 2.66 (range, 8–18), while in group B was 15.88 ± 2.71 (range, 10–18). Sixty-nine of 100 patients in our study had associated intra-articular lesions. We had 5 early complications and 36 late complications. The study suggests that there are no differences between ARIF and ORIF treatment in Schatzker type I fractures. ARIF technique may increase the clinical outcome in Schatzker type II–III–IV fractures. In Schatzker type V and VI fractures, ARIF and ORIF techniques have both poor medium- and long-term results but ARIF treatment, when indicated, is the best choice for the lower rate of infections.     

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.     

Fracture dislocation of the talus combined with pilon or bimalleolar fracture: a report of two cases

Talar fractures are uncommon and talar body fracture dislocations are still rare. Simultaneous fractures of the ankle and the talar body are rare and the reported incidence in the literature is fewer than 1% of the ankle fractures. We present two cases of patients, who sustained a simultaneous fracture dislocation of talar body with fracture of medial malleolus and/or tibial pilon. The patients were treated with open reduction and internal fixation of talus through the malleolar fracture. They were evaluated at 1 year (case 1) and 8 years (case 2) of follow-up. The prognosis after this fracture dislocation is poor because of the very high risk of avascular necrosis and arthritis, even after anatomic reduction.     

Interference Screw Technique for Arthroscopic Reduction and Internal Fixation of Compression Fractures of the Tibial Plateau

Arthroscopic reduction and internal fixation (ARIF) is recommended as state-of-the-art treatment for patients with pure compression fracture of the tibial plateau. We describe a new technique for ARIF of pure compression tibial plateau fractures that uses a cannulated, bioabsorbable interference screw. After a guide pin is placed in the center of the compressed fragment and a tamp is used to elevate the fracture (with bone grafting as desired), the interference screw is advanced over the guide pin, resulting in both elevation and buttressing of the fracture. As compared with previously described techniques in which percutaneous buttress screws were used, ARIF attained with an interference screw via the tibial metaphyseal window allows substantially improved efficiency of surgical steps, improved preservation of the soft tissue envelope, definitive articular reduction under arthroscopic visualization, use of a bioabsorbable implant, and elimination of the need for fluoroscopy.     

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.     

Bosworth-type fibular entrapment injuries of the ankle: the Bosworth lesion. A report of 6 cases and literature review

OBJECTIVES: To evaluate patients with Bosworth-type fibular entrapment injuries of the ankle. DESIGN: Retrospective clinical study and analysis of the literature. SETTING: University hospital. PATIENTS: Six cases treated for Bosworth-type fibular entrapment injuries (the Bosworth lesion) in the period 2001 to 2004. INTERVENTION: Five patients were treated with open reduction and internal fixation (ORIF), and 1 patient was treated with closed reduction and cast. RESULTS: All patients treated by ORIF healed without complications with a good subjective outcome. In 1 case treated nonoperatively, an ankle fusion had to be performed 2 years after injury for severe osteoarthritis. Additionally, we have recorded 3 cases, 2 not previously described in the literature, in which the fracture of the fibula was located at the middle or proximal third of its shaft.In the literature we found another 54 cases with dislocation of the fibula behind the posterior tubercle of the distal tibia. The analysis showed that morphology of the Bosworth lesion, as we prefer to refer to this complex fracture-dislocation, changes with age and may be divided into 3 basic types. In children and adolescents the dislocation of the distal fibula is associated with epiphyseolysis of the distal tibia; in young adults the fibula dislocates without fracture; in middle-aged and older adults, the dislocated fibula fractures, probably because of the decreased elasticity. CONCLUSIONS: The Bosworth lesion is a severe injury of the ankle, and its successful treatment requires a correct diagnosis based on careful initial clinical and radiographic evaluation and early surgical treatment.
