ObjectiveTo explore effectiveness of reduction and internal fixation via modified anterolateral supra-fibular-head approach in treatment of tibial plateau fractures involving posterolateral column.MethodsBetween January 2016 and September 2018, 19 patients diagnosed as tibial plateau fractures involving posterolateral column were treated with reduction and internal fixation via modified anterolateral supra-fibular-head approach. There were 11 males and 8 females with an average age of 43.2 years (range, 28-65 years). The causes of tibial fracture were traffic accident (12 patients), falling injury (5 patients), and falling from height (2 patients). According to the Schatzker typing, the tibial fractures were rated as type Ⅱ in 9 cases, type Ⅲ in 4 cases, type Ⅴ in 4 cases, and type Ⅵ in 2 cases. The time from injury to operation was 5-13 days (mean, 8.5 days). There were 2 patients with osteoporosis. The operation time, intraoperative blood loss, and postoperative complications were recorded. The knee X-ray film was reviewed regularly to observe the fracture healing. At last follow-up, the fracture reductions were evaluated by Rasmussen radiological score. The knee joint function was evaluated by Hospital for Special Surgery (HSS) score system.ResultsThe average operation time was 95 minutes (range, 65-130 minutes). The average intraoperative blood loss was 220 mL (range, 150-350 mL). All incisions healed by first intention. No complications such as infection or deep venous thrombosis occurred. All patients were followed up 12-20 months (mean, 15.4 months). X-ray films showed that the fractures healed with the healing time of 12-20 weeks (mean, 14.5 weeks). No complications such as loosening or breakage of internal fixation occurred. At last follow-up, according to the Rasmussen radiological score, the fracture reductions were evaluated as excellent in 13 cases, good in 4 cases, fair in 1 case, and poor in 1 case. HSS scores of knee joint function were excellent in 14 cases, good in 3 cases, fair in 1 case, and poor in 1 case. The knee joint range of motion was 90°-135°, with an average of 113.4°.ConclusionApplication of modified anterolateral supra-fibular-head approach in reduction and internal fixation for tibial plateau fractures involving posterolateral column has the advantages of full exposure, less trauma, safety, and reliable reduction and fixation.
