Abstract:
The choice of the donor tendon in tendon reconstruction of the hand theoretically influences the results of the surgery because of the interactions of its structure with the healing process. The objective of our study was to specify the surgical bases of vascularized extensor indicis proprius (EIP) in tendon reconstruction of the hand and to present its application from a series of observations. According to our observations, the EIP\'s vascularization arises from a branch of the 2nd dorsal metacarpal artery, 3-4 cm proximally to the metacarpophalangeal joint (MCP). We demonstrate the feasibility and effectiveness of a vascularized EIP graft for finger flexor tendon reconstruction, for defects of the extensor mechanism at the MCP joint level and for reconstruction of the extensor pollicis longus. Our biomimetic approach in tendon reconstruction has led us to factor in the complexity of the tendon and peritendinous structure. The use of vascularized EIP offers theoretical advantages for the tendon healing process, demonstrates encouraging first results with interesting versatility and very low iatrogenicity.
摘要:
在手的肌腱重建中供体肌腱的选择理论上会影响手术的结果,因为其结构与愈合过程的相互作用。我们研究的目的是指定血管化伸肌(EIP)在手肌腱重建中的手术基础,并从一系列观察中介绍其应用。根据我们的观察,EIP的血管形成来自第二掌背动脉的分支,掌指关节(MCP)近3-4厘米。我们证明了血管化EIP移植物用于手指屈肌腱重建的可行性和有效性,用于MCP关节水平的伸肌机制的缺陷和长伸肌的重建。我们在肌腱重建中的仿生方法使我们考虑了肌腱和肌腱周围结构的复杂性。血管化EIP的使用为肌腱愈合过程提供了理论优势,展示了令人鼓舞的第一个结果,具有有趣的多功能性和非常低的医源性。
