For many years, end-to-end arthrodesis of a proximal interphalangeal joint arthrodesis to correct hammer digit deformity has been fixated with a Kirschner wire (K-wire). For this particular hammer digit deformity correction, we attempted to determine the effectiveness of the SmartToe(®) intramedullary shape memory implant compared with the K-wire. In a retrospective analysis of 28 cases, we evaluated several important parameters at baseline, postoperative days 7, 14, 21, 28, and 56, and 6 months for pain, complications, arthrodesis achieved, and return-to-work status. The SmartToe(®) outperformed the K-wire in all categories, with no evidence of significant complications, compared with multiple complications for patients in the K-wire arm of the study. This study demonstrates that the SmartToe(®) is a reasonable choice for fixation of proximal interphalangeal joint arthrodesis in hammer digit correction.
多年来，近端指间关节融合术用于矫正锤状指畸形的端到端融合一直采用克氏针（K 针）固定。对于这种特定的锤状指畸形矫正，我们试图确定 SmartToe® 髓内形状记忆植入物与 K 针相比的有效性。在一项对 28 例病例的回顾性分析中，我们在基线、术后第 7 天、14 天、21 天、28 天、56 天以及 6 个月时评估了疼痛、并发症、融合情况以及恢复工作状态等几个重要参数。与研究中 K 针组患者出现多种并发症相比，SmartToe® 在所有类别中均表现优于 K 针，且无明显并发症迹象。这项研究表明，SmartToe® 是矫正锤状指时近端指间关节融合固定的合理选择。
