Autograft tendon harvested from the long toe extensors are of great utility as intercalary grafts in upper extremity reconstruction. However, standard full-length harvest is complicated by the presence of extensor retinacula and multiple juncturae between adjacent extensors, which often necessitate extensive dissection, increasing the potential for morbidity. We describe a modified technique for partial harvest of the long toe extensors, which is performed entirely proximal to the superior extensor retinaculum. This technique requires a single incision and provides adequate length of graft for the majority of forearm to fingertip reconstructions. The technique is described in the context of our preliminary cadaver findings, with a case example provided to further illustrate the utility of this technique.
取自长趾伸肌的自体肌腱作为上肢重建中的嵌插移植材料具有很大的实用价值。然而，标准的全长取材因存在伸肌支持带以及相邻伸肌之间的多条腱间结合而变得复杂，这往往需要进行广泛的解剖，增加了发病风险。我们描述了一种改良技术，用于长趾伸肌的部分取材，该操作完全在上伸肌支持带近端进行。此技术只需一个切口，为大多数从前臂到指尖的重建提供足够长度的移植材料。该技术是根据我们初步的尸体研究结果进行描述的，并提供了一个病例示例以进一步说明该技术的实用性。
