Although there is consensus that closed tendinous mallet finger injuries should be treated conservatively, the best method of immobilization to be used is not clear and the existing data in the literature are not conclusive. The aim of this study is to compare the results of four different immobilization methods used in the conservative treatment of tendinous mallet finger injury.
Ninety-six patients with tendinous mallet finger injury were treated with four different immobilization methods (stack orthosis, thermoplastic orthosis, aluminum orthosis, and Kirschner wire [K-wire] immobilization). The patients then were assessed with distal interphalangeal joint extensor lag, total active motion (TAM), grip strength, and Abouna and Brown Criteria.
No significant difference was found between four immobilization methods in extensor lag and TAM at the 8th and 12th weeks. According to grip strength assessment, stack orthosis group was found to have significantly better results than the K-wire and aluminum orthosis groups at 12 weeks, while the difference was not significant versus the thermoplastic orthosis group.
In this first study making multiple comparisons between four immobilization methods used in the treatment of tendinous mallet finger injury, the only significant difference detected between the groups was the superior grip strength with stack orthosis compared with K-wire immobilization and aluminum orthosis.
尽管对于闭合性锤状指肌腱损伤应采取保守治疗已达成共识，但目前尚不清楚最佳的固定方法，且现有文献中的数据也不具有结论性。本研究旨在比较四种不同固定方法在保守治疗锤状指肌腱损伤中的治疗结果。
96 例锤状指肌腱损伤患者采用四种不同的固定方法（叠层支具、热塑支具、铝制支具和克氏针固定）进行治疗。然后，通过远侧指间关节伸肌迟滞、总主动活动度（TAM）、握力和 Abouna 和 Brown 标准对患者进行评估。
在第 8 周和第 12 周，四种固定方法在伸肌迟滞和 TAM 方面无显著差异。根据握力评估，在第 12 周时，叠层支具组的结果明显优于克氏针和铝制支具组，而与热塑支具组的差异无统计学意义。
在这项首次对四种用于治疗锤状指肌腱损伤的固定方法进行比较的研究中，仅发现叠层支具组与克氏针固定组和铝制支具组相比，握力具有显著优势。
