Abstract：
Lateral plating alone has been postulated as an alternative for fixation of bicondylar tibial plateau fractures in attempts to limit morbidity associated with dual plating. Characterization of fracture patterns that may facilitate lateral plating alone for bicondylar tibial plateau fractures is not well established. The authors analyzed radiographic and clinical outcomes of isolated lateral plating in patients with at least 6 months of follow-up. Of 56 patients identified, 37 (66%) had 41 AO Foundation (AO)/Orthopaedic Trauma Association (OTA) C1/C2 fractures with 19 (34%) presenting with 41 C3 fractures. Mean posteromedial articular fracture angle (PMAFA) was 69.9 degrees, with an average of 1.3 medial articular fragments. Only 16 patients (28%) had a PMAFA under 45 degrees. There were no cases of nonunion, and five patients (8.9%) developed wound infection during follow-up. Four patients (7.1%) experienced malreduction over three degrees, and eight patients (14.3%) experienced change in alignment over the follow-up duration, indicating some risk of inadequate fixation with this technique.

摘要：
为了限制与双钢板相关的发病率，仅外侧钢板已被假定为固定双髁胫骨平台骨折的替代方法。对于双髁胫骨平台骨折，可能仅进行外侧钢板治疗的骨折模式的表征尚不明确。作者分析了经过至少6个月随访的患者的放射学和临床结果。在确定的56名患者中，37例（66％）的AO基金会（AO）/骨科创伤协会（OTA）C1/C2骨折41例，其中19例（34％）的C3骨折41例。后内侧关节骨折平均角度(PMAFA)为69.9°,平均有1.3个内侧关节碎片。只有16名患者（28％）的PMAFA低于45度。没有骨不连的情况，5名患者(8.9%)在随访期间出现伤口感染。四名患者(7.1%)出现三度以上的畸形复位,8名患者（14.3%）在随访期间出现了排列变化，表明这种技术存在固定不足的风险。（外科骨科杂志进展33（2）：088-092，2024）。
