Superior dislocation of the fibular head associated with a tibial shaft fracture.

Superior dislocation of the proximal tibiofibular joint occurred in a 34-year-old woman who sustained a Grade 3B open left tibial fracture. An external fixator was applied to the tibia, and the tibiofibular joint was treated by closed reduction. Two bone graftings were performed, and the patient ultimately required a fibular osteotomy to allow tibial impaction. At 10 months posttrauma, the patient is fully weight-bearing and has no pain either at the tibia or the tibiofibular joint.     

Ipsilateral vascularised fibular transport for massive defects of the tibia

The ipsilateral and contralateral fibulae have been used as a vascularised bone graft for loss of tibial bone usually by methods which have involved specialised microvascular techniques to preserve or re-establish the blood supply. We have developed a method of tibialisation of the fibula using the Ilizarov fixator system, ipsilateral vascularised fibular transport (IVFT), and have used it in five patients with massive loss of tibial bone after treatment of an open fracture, infected nonunion or chronic osteomyelitis. All had successful transport, proximal and distal union, and hypertrophy of the graft without fracture. One developed a squamous-cell carcinoma which ultimately required amputation of the limb. The advantage of IVFT is that the fibular segment retains its vascularity without the need for microvascular dissection or anastomoses. Superiosteal formation of new bone occurs if the tibial periosteal bed is retained. Other procedures such as corticotomy and lengthening can be carried out concurrently.     

Outcome of limb reconstruction system in tibial infected non-union and open tibial diaphysial fracture with bone loss

IntroductionIncidence of open fractures of the long bones is increasing due to the increase in road traffic accidents (RTA) which leads to an increased incidence of complex non-unions of long bones. Patients are usually operated many times for fracture fixation (and healing) or to eradicate infection, which causes soft tissue scarring and devitalization of any surviving bone.ObjectiveIn this study, we assess the outcome of the Limb reconstruction system in tibial infected non-union and open tibial diaphyseal fracture with bone loss.MethodIt is a prospective study conducted on 15 patients and patients included in this study having compound fractures of shaft tibia with bone loss classified by Gustilo-Anderson open fracture classification. With the defect in the distal tibia, proximal corticotomy 1.5 cm distal to the last screw in the proximal clamp and proximal to distal transports were done and vice versa. All patients were evaluated with the ASAMI scoring system into bone results and functional results.ResultsIn the majority of patients, the injury was caused by road traffic accidents 80% of cases. Out of 15 cases, 2 belong to the upper 3rd, 9 cases belong to the middle 3rd and 4 cases belong to the lower 3rd of shaft tibia. The union time ranges from 4 to 11 months but the maximum union was achieved in 7–9 months in 8 (53.33%). Pin tract infection was reported in two (13.33%) patients who became better with regular dressing. Ankle stiffness was present in one case (6.67%), most probably due to improper physiotherapy.According to ASAMI Criteria excellent radiological results were present in 11 (73.33%) cases, good results were found in 4 (26.67) cases and excellent functional results were observed in 7 cases (46.67%) and good results were found in 8 (53.33%) cases. Infection was cured in all patients and did not recur till the last follow-up.ConclusionsAdvantages of rail fixator include less invasive surgery, early weight-bearing, less infection, less blood loss, prevention of diffuse osteoporosis and atrophy, preservation of limb function, no need for bone grafting, correction of deformity during the process of healing, thus no need for a second surgery. Non-union, bone defect, and deformity can be corrected simultaneously. Hence, we recommend the use of this system (rail fixator) especially for infected non-union of long bones and compound fractures with bone loss.     

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.     

Dislocation of the proximal tibiofibular joint in association with a tibial shaft fracture: two case reports and a literature review

Dislocation of the proximal tibiofibular joint (PTFJ) in association with a displaced tibial shaft fracture and an intact fibula is an exceedingly rare injury. We present 2 cases of tibia fractures associated with an intact fibula and a PTFJ dislocation. The first case involves a man who sustained a closed spiral fracture of the distal tibial shaft, with an intact fibula, an anterolaterally dislocated PTFJ, and a partial tear of the lateral collateral ligament. The tibia was percutaneously plated, and the PTFJ was reduced and then stabilized with temporary screw fixation. The second case involves a woman who sustained a closed fracture of the tibia in association with a PTFJ dislocation. The tibia was fixed with an intramedullary nail, and the PTFJ was similarly reduced and fixed with a temporary screw. We also provide a brief literature review focusing on classification of PTFJ dislocations, mechanism of injury, associated injuries, and treatment options.

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.     

Distraction osteogenesis in a segmental tibial delayed union

The treatment of open segmental tibia fracture associated with bone loss is very demanding. Despite the fact that the principles of the distraction osteogenesis are being followed commonly in these fractures, there is not a single technique that fits all situations. In this article, we report a case where the initial fractures were stabilized with a monolateral bridging external fixator with no evidence of callus formation 6 weeks later. The proximal fracture was used as “an osteotomy” for bone transport after a latent period of 6 weeks of compression. The successful outcome in this patient, confirms that distraction of a delayed union even when it is mobile, can lead to bone formation and healing of the delayed union.     

Bifocal compression-distraction in the acute treatment of grade III open tibia fractures with bone and soft-tissue loss: a report of 24 cases

OBJECTIVE: To evaluate the results of bifocal compression-distraction method for the acute treatment of open tibia fractures with bone and soft-tissue loss. DESIGN: Patients were selected for bifocal compression-distraction (shortening and lengthening) who had open tibia fractures with bone and soft-tissue loss and a Mangled Extremity Severe Score of 6 and below indicating good leg viability. PATIENTS: Bifocal compression-distraction osteogenesis using the Ilizarov type circular external fixator was applied to 24 patients with 14 grade IIIA and 10 grade IIIB open tibia fractures with bone and soft-tissue loss. Mean age of the patients was 30.6 years (range 18-53). The mean bone defect was 5 cm (range 3-8.5). The mean soft tissue defect was 2.5 x 3.5 (1 x 2-10 x 5) cm. INTERVENTIONS: Acute shortening at the fracture site was done for patients with bone defects up to 3 cm to achieve apposition of bone ends. Gradual shortening at a rate of 2 mm/d was done for patients who had bone defects more than 3 cm. Leg length discrepancy was overcome by lengthening at the same time through a corticotomy at a proximal or distal level depending on fracture localization, until there was equalization of leg lengths. RESULTS: Mean follow-up period was 30 months (range 18-60). Mean bone healing time was 7.5 months (range 4-11). The mean time in external fixation was 7.1 months (range 3-10), and the average external fixator index was 1.4 months/cm. Results were evaluated using the Paley bone and functional assessment scores. The bone assessment results were excellent in 21 and good in 3 patients. Functional assessment scores were excellent in 19, good in 4, and fair in 1 patient. Pin site infections were present in 10.7% of the pin sites. There were 52 complications in 24 patients, for a complication rate per patient of 2.08. Of the complications, 48.1% were problems (minor complications), 38.5% obstacles (major complications requiring a surgical solution), and 13.4% sequelae (true complications). Minor complications included soft tissue inflammation and infection, translation/angulation, and delayed maturation during distraction and transient knee contracture and loss of motion. All grade 1 and 2 soft tissue inflammations and infections healed with nonoperative therapy. Major complications included pin tract infection and reinfection, equinus deformity, frame failure, and premature consolidation, all of which required additional surgery to correct the problem. Sequelae included leg length discrepancy, loss of knee/ankle range of motion, knee flexion contracture, malalignment, and chronic osteomyelitis. CONCLUSION: Bifocal compression-distraction osteogenesis is a safe, reliable, and largely successful method for the acute treatment of open tibia fractures with bone and soft-tissue loss. Further nonoperative or operative treatment can correct most complications.     

AO external fixator for definitive treatment of an open distal tibia fracture during the COVID-19 pandemic

BackgroundThe accepted gold standard for primary treatment of long bone open fractures consists of aggressive debridement, irrigation and temporary external fixation. Removal of the external fixator followed by definite internal fixation is recommended within the first two weeks after the injury to obtain a more stable fixation, alleviate rehabilitation and to avoid pin infection.Materials & MethodsHere, we report a case of a Gustilo IIIB open tibia fracture with extended soft tissue degloving of the distal tibia. Following removal of the AO external fixator, plate fixation and soft tissue coverage with a free flap, implant loosening occurred warranting a return to external fixation. The patient did not return for follow-up due to a prolonged COVID-19-quarantine and no further treatment was installed.Results & ConclusionsThe patient returned after 6 months with the fractures and soft tissues fully healed. In specific situations, the external fixator may be used as a definitive form of treatment.     

Management of unstable open and closed tibial fractures using the Ilizarov method.

Forty-one consecutive tibial diaphyseal fractures that required operative stabilization were treated using the external fixator and concepts of compression-distraction of Ilizarov. Eleven fractures had bone loss greater than 1 cm and were managed by simultaneously compressing the fracture gap and distracting through a corticotomy site to maintain extremity length. Thirty tibial fractures consisted of closed unstable and open fractures that were managed using the external fixator, emphasizing immediate weight bearing and gradual compression at the fracture site. Twenty-six fractures in 23 patients were available for follow-up evaluation six to 9.5 months after bone healing. There were six closed, two Grade I, eight Grade II, five Grade IIIA, and five Grade IIIB fractures. Serial wound debridements, wet-to-dry-dressing changes, wound- and fracture-site compressions (13 fractures), and split-thickness skin grafts (eight wounds) were used to accomplish wound closure. Chronic infections did not occur. All fractures healed from 12 to 47 weeks without bone grafting. Eight transosseous fixation wires are used, only two of which transfixed significant muscle. Approximately 10% of the 248 wire sites became inflamed and nine wire sites were treated for infection with antibiotics, skin release around the offending wire, or wire removal. Three wires fractured and one wire was replaced. One ring sequestrum occurred and responded to curettement. Angulation of 7 degrees-9 degrees occurred in five fractures (19%). The results were good or excellent in 25 fractures. One patient with 9 degrees varus in a distal fracture refused correction. Operative time was 60 to 90 minutes after developing a satisfactory protocol for frame application. This method allows immediate functional stabilization of tibial diaphyseal fractures and postoperatively allows ease of fracture gap closure and compression. The frame can be left in place for the duration of the fracture care. Application of the Ilizarov external fixator is slightly more complicated than traditional large pin fixators and requires more attention to detail intraoperatively and postoperatively, but can be a versatile tool in the management of complex tibial shaft fractures.     

Stress fracture as a complication of autogenous bone graft harvest from the distal tibia

BACKGROUND: Autogenous bone graft from the distal tibia provides cancellous bone graft for foot and ankle operations, and it has osteogenic and osteoconductive properties. The site is in close proximity to the foot and ankle, and published retrospective studies show low morbidity from the procedure. METHODS: One-hundred autografts were obtained from the distal tibia between 2000 and 2003. In four cases the distal tibial bone graft harvest resulted in a stress fracture. There were three women and one man. RESULTS: The average time of diagnosis of the stress fracture from the operation was 1.8 months. All stress fractures healed with a short course (average 2.4 months) of cast immobilization. CONCLUSIONS: This study demonstrated that a stress fracture from the donor site of autogenous bone graft of the distal tibia occurs and can be successfully treated nonoperatively.

Contaminated fractures of the tibia: A comparison of treatment modalities in an animal model

External fixation is the current standard treatment for skeletal stabilization of open tibial fractures, but intramedullary fixation techniques have become increasingly popular. The aim of this study was to compare, in an animal model, the susceptibility to infection of contaminated fractures stabilized with external fixation with that of contaminated fractures fixed with intramedullary locking nails with or without reaming. A unilateral osteotomy of the tibia was performed in 15 goats under general anesthesia. Each osteotomy was stabilized with either (a) a unilateral biplanar external fixator, (b) an 8 mm diameter intramedullary rod inserted without reaming of the medullary cavity, or (c) a 10 mm diameter rod inserted after reaming. A standardized inoculum of Staphylococcus aureus, 10³ colony forming units per milliliter, was placed at each osteotomy site on a piece of absorbable gelatin sponge, to simulate contamination of an open fracture. Antibiotics were not administered. The animals were allowed full activity after the procedure. Fourteen days postoperatively, the animals were killed, radiographs of the tibiae were taken, and the tibiae were harvested in a sterile manner. Multiple specimens for quantitative microbiological analysis were taken from the fracture site and from sites 3 cm distal and 6 cm proximal to the fracture. Additional specimens of bone were taken for histological study. Clinical, radiographic, and microbiological analysis demonstrated that, in this animal model, there were significantly fewer and less severe infections in fractures fixed with external fixation than in those fixed with an intramedullary nail with or without reaming. There was marked cortical necrosis in tibiae that had been fixed with nailing and reaming.

Abstract：

Objective To evaluate clinical results of primary shortening plus secondary lengthening of the tibia for sever tibial fractures. Methods From May 2006 to August 2009, 5 men with severe open tibial fracture were treated with primary shortening plus secondary lengthening of the tibia in our center. They were aged from 23 to 41 years (average, 35 years) . Four cases were Gustilo type MB and one was Gustilo type M C. The primary procedure included debridement, shortening of the tibia and temporary fixation with a unilateral external fixator, and arterial anastomosis in cases of vessel injury. The wounds healed primarily in one case, after skin graft in 2 cases, and after flap transplantation in 2 cases. After wound healing, secondary lengthening of the tibia was performed following osteotomy of the proximal tibia with an Ilizarov fixator to restore the length of the injured leg. The average shortening was 4. 2 cm (range, 3 to 5 cm). Results The average follow-up period was 20 months (range, 18 to 24 months). All the wounds were healed without signs of osteomyelitis. All the fractures united. The mean bone healing time was 9. 6 months (range, 6 to 12. 5 months) . The average healing index was 1. 7 months/cm. A normal length was restored in all the affected lower limbs. By Paley functional assessment system, 3 cases were excellent, one was good and one was fair. Conclusion Primary shortening plus secondary lengthening of the tibia is a reliable and successful method for sever tibial fractures, because it can simplify management and minimize the need for flap coverage.

Management of a long segmental defect at the proximal meta-diaphyseal junction of the tibia using a cylindrical titanium mesh cage

This case report describes a Gustilo Anderson type IIIB tibia fracture associated with extensive segmental bone loss at the proximal meta-diaphyseal junction associated with a tibial plateau fracture and an avulsion of the tibial tubercle. After the tibial plateau fracture was stabilized using cannulated lag screws, the shaft fracture was stabilized using a statically locked intramedullary nail in combination with a cylindrical titanium mesh cage and cancellous bone graft. The soft tissue defect was covered with local flaps. Immediate full weight bearing was initiated, and early functional recovery was achieved. At the final follow-up, plain radiographs demonstrated excellent limb alignment, and bony healing with computed tomography examination revealed bony ingrowth through the cage. This technique may be a reasonable alternative in the treatment of segmental bone loss of long bones.
