The authors present a case of extension loss of great toe caused by entrapment neuropathy of a peroneal nerve due to an osteochondroma of the proximal fibula. Plain radiographs revealed no bony abnormality around the foot or ankle, but a sessile exophytic bony growth at the proximal fibula. A positive Tinel sign in this area led us to a suspicion of compressive neuropathy of the peroneal nerve, and a subsequent electrophysiologic study confirmed the entrapment neuropathy. The peroneal nerve was decompressed by excisional biopsy. At 3 months postoperatively, normal full extension of the great toe was completely restored. The current case deserves attention in that the only clinical manifestation of peroneal nerve entrapment neuropathy by the osteochondroma at the fibular neck was extension loss of great toe.
作者报告了一例因腓骨近端骨软骨瘤导致的腓总神经嵌压性神经病引起的大脚趾伸展丧失病例。平片显示足部和踝关节周围无骨异常，但腓骨近端有一基底宽的外生性骨性生长物。该区域的 Tinel 征阳性使我们怀疑腓总神经受压性神经病，随后的电生理研究证实了嵌压性神经病。腓总神经通过切除活检进行减压。术后 3 个月，大脚趾完全恢复正常的完全伸展。该病例值得注意的是，腓骨颈骨软骨瘤引起的腓总神经嵌压性神经病的唯一临床表现是大脚趾伸展丧失。
