The theoretic disadvantage of dynamic tendon transfers is the perception that they are "more complex" than static procedures. The latter may provide a simple solution to claw deformity in a subset of patients; however, they completely disregard the disability associated with loss of the intrinsic musculature. Dynamic procedures reconstruct in part the deficient intrinsic forces and are thus capable of correcting the deformity and some disabilities associated with ulnar nerve palsy. In our practice, we have consistently achieved reasonable correction of claw deformity and improvement in tendon synchrony and grip strength with a modified Stiles-Bunnell, flexor digitorum superficialis tendon transfer.
动态肌腱转移的理论缺陷在于人们认为它比静态手术更“复杂”。后者可能为一部分患者的爪形畸形提供了一个简单的解决方案；然而，它们完全忽略了与内在肌肉丧失相关的残疾。动态手术部分重建了缺失的内在力量，因此能够纠正尺神经麻痹相关的畸形和一些残疾。在我们的实践中，我们一直通过改良的 Stiles-Bunnell 、指浅屈肌腱转移术实现了对爪形畸形的合理矫正，并改善了肌腱协调性和握力。
