We evaluated the healing rate, complications, and functional outcomes in 32 adult patients with very short metaphyseal fragments in fractures of the distal tibia treated with a polyaxial locking system. The average distance from the distal extent of the fracture to the tibial plafond was 11 mm. All fractures healed and the average time to union was 14 weeks. Six patients (19%) reported occasional local disturbance over the medial malleolus. There were two cases of postoperative superficial infections and evidence of delayed wound healing. Using the American Orthopaedic Foot and Ankle Society ankle score, the average functional score was 87.3 points (of 100 total possible points). Our results show the polyaxial locking plates, which offer more fixation versatility, may be a reasonable treatment option for distal tibia fractures with very short metaphyseal segments.
我们评估了32例采用多轴锁定系统治疗的成人胫骨远端骨折且干骺端骨折块非常短的患者的愈合率、并发症及功能结果。骨折远端至胫骨平台的平均距离为11毫米。所有骨折均愈合,平均愈合时间为14周。6例患者(19%)报告内踝处偶尔有局部不适。有2例术后浅表感染及伤口愈合延迟的证据。采用美国矫形足踝协会踝关节评分,平均功能评分为87.3分(满分100分)。我们的结果表明,提供更多固定灵活性的多轴锁定钢板可能是治疗干骺端节段非常短的胫骨远端骨折的合理选择。
