Abstract
The purpose of this study is to determine the indications and effectiveness of hybrid external fixation in the treatment of tibial plateau fractures and to evaluate the patient’s functional recovery.
Twenty-seven patients with 28 intra-articular fractures of the proximal tibia were surgically treated with hybrid external fixation in a two years period (1999–2001). There were 25 patients (19 men and 6 women) available for the last follow up evaluation. The mean age was 35 years (17–76). According to Schatzker classification, there were 6 fractures type V and 22 type VI. Three of them were open fractures. The method included, indirect reduction based on ligamentotaxis and compression of the fractured segments with olive pins, in most patients. Additional limited internal fixation with free screws was also performed in 5 cases. Open reduction was necessary in 6 patients. Mobilization of the injured articulation was started at the third postoperative day, while full weight bearing was allowed after three months. The fixator was removed in average 12th week. Final evaluation was done according subjective, functional, clinical and radiological criteria. Mean follow up period was 14 months.
All fractures except one united at an average time of 13, 5 weeks. Twenty-two patients (77.6%) graded as excellent and good, hi detail, subjective results were acceptable in 72%, functional in 84%, clinical in 70% and radiological in 80%. Complications included one axial deformity, one septic pseudarthrosis, one peronial palsy and superficial pin path infections.
The use of hybrid external fixation in the comminuted tibial plateau fractures (Schatzker V, VI), insure good restraining and early union, avoid major soft tissue complications and allow quick mobilization and functional recovery of the knee joint. Moreover it is an application rather atraumatic because, only occasionally requires open reduction.
