Spontaneous Extensor Tendon Rupture in Patients with Rheumatoid Arthritis of the Hand

手部類風濕性關節炎之自發性伸肌腱斷裂

摘要


伸肌腱腱鞘滑膜炎在有風濕性關節炎病人的手上是一個相當常見的問題,其最佳的治療在於肌腱斷裂之前以藥物控制或行肌腱鞘滑膜切除術來避免斷裂發生,一旦發生肌腱斷裂時可以肌腱移轉來達到相當程度伸肌腱功能的回復,瞭解風濕性關節炎造成肌腱磨損性斷裂之機轉及除去其致病性因素是成功重建的重點,這包含了預防性腱鞘滑膜切除術,各種肌腱斷裂的重建及遠端尺骨切除。本文報告五例風濕性關節炎造成各種肌腱斷裂的重建經驗及文獻回顧。

Extensor tenosynovitis is a common problem in patients with rheumatoid hands. The best treatment is prevention, either using medical management or surgical tenosynovectomy before tendon rupture occurs. Once a rupture has occurred, tendon reconstruction with a tendon transfer provides a reasonable chance of restoration of extensor function. There are complex mechanisms which induce tendon attrition rupture in patients with rheumatoid hands. Complete assessment of the patients along with a clear understanding of the progression of rheumatoid deformities is the key to successful reconstruction. Combined prophylactic dorsal synovectomy, ruptured tendon reconstruction, and distal ulnar resection were seemed effective treatment for resolving these problems. The surgical plan varied from patient to patient and was tailored accordingly. We present our experiences in treating five patients and we also reviewed the relative literature.
