The management of bicondylar tibial plateau fractures is challenging. A lateral locking plate offers an alternative method to traditional dual plating to avoid further stripping of soft tissue. Nevertheless, the rate of malreduction and fixation loss remains high. From 2007 to 2009, we performed open reduction and fixation with unilateral locked plating to directly reduce the fracture in 15 patients with bicondylar plateau fracture. The average follow-up duration was 16.2 months (range: 12-30 months), and the average age of the patients was 43 years (range: 19-64 years). All fractures were Orthopaedic Trauma Association type 41-C. Postoperative radiographic alignment was evaluated immediately and at 2-4 weeks, 8-12 weeks, 5-7 months, and 11-13 months. Both Oxford knee score and Hospital for Special Surgery knee score were used to evaluate functional outcomes. The average duration within which union was achieved was 4.8 months (range: 2-10 months). One patient incurred wound dehiscence; however, there was no case of deep infection. Malreduction occurred in one patient (6.7%) while fixation loss occurred in three patients (20%) with subsidence of the posteromedial fragment and varus malalignment. Despite the malreduction rate being lower in our study than in previous studies involving unilateral locked plating, a high rate of fixation loss was recorded. Per our limited experience, we believe that unilateral locked plating may have limitations in patients with selective patterns of bicondylar tibial plateau fractures.
双髁胫骨平台骨折的治疗颇具挑战性。外侧锁定钢板为避免进一步软组织剥离提供了一种替代传统双钢板固定的方法。然而,复位不良和固定丢失的发生率仍然较高。2007 年至 2009 年,我们对 15 例双髁胫骨平台骨折患者采用单侧锁定钢板行切开复位内固定,直接复位骨折。平均随访时间为 16.2 个月(范围:12-30 个月),患者平均年龄为 43 岁(范围:19-64 岁)。所有骨折均为 Orthopaedic Trauma Association 41-C 型。术后即刻及术后 2-4 周、8-12 周、5-7 个月、11-13 个月进行影像学对线评估。采用 Oxford 膝关节评分和纽约特种外科医院膝关节评分评估功能结果。平均愈合时间为 4.8 个月(范围:2-10 个月)。1 例患者发生伤口裂开,但无深部感染。1 例(6.7%)患者发生复位不良,3 例(20%)患者出现后内侧骨块沉降和内翻对线不良导致固定丢失。尽管我们的研究中复位不良发生率低于既往单侧锁定钢板固定的研究,但固定丢失发生率较高。根据我们的有限经验,我们认为单侧锁定钢板在某些双髁胫骨平台骨折患者中可能存在局限性。
