摘要
目的:对骨间后神经终末支卡压引起腕背痛的机理进行探讨。方法:对7具福马林固定的成人尸体两侧前臂骨间后神经进行解剖学研究,结合临床13例骨间后神经终末支卡压征的病史进行分析。结果:该神经沿指总伸肌的腱鞘桡侧缘向腕背行走,于头月关节囊处稍有膨大,并分成4～6支细小的神经支走向两侧、远方和深层。此处神经被纤维结缔组织紧紧固定在关节囊上,当腕关节背伸时该段神经呈弯曲松弛状,掌屈时神经被拉紧。临床发现该征发病与腕关节过多活动有关,腕掌屈时疼痛加剧,于指总伸肌桡侧腕背横纹处(该神经膨大分支处),有一显著而固定的压痛点。13例经压痛点局封后,随访7个月至2年,11例未复发,2例复发。结论:对腕背疼痛病例仔细检查、分析,可能会发现骨间后神经卡压征并不罕见。
Objective: To investigate the mechanism of dorsal wrist pain induced by compression of the ending branches of the posterior intcrosscous nerve. Methods: Anatomical studies wcrc done on both sides of posterior interosseous nervcs in 7 adult cadavers. 13 patients with posterior intcrosseous nerve ending compression were treated clinically. Results: The posterior intcrosscous ncrvc ran along thc radial side of extcnsor digitorum tendon sheath, had slight enlargement at the capitate-lunate joint capsule, then gave off 4 to 6 thin branches to distal, lateral and inferior aspcct. The ncrvc was anchored on thc capsule by fibrous tissue and was loose when the wrist extended while tight when the wrist flexed. Clinically, the compression was relation to over activity of the wrist. The pain exasperated with wrist flexion. A Point of obvious tenderness could be identified at the crossing area of the radial side of extensor digitorum and dorsal wrist crease. All the 13 patients were treated by local blocking 11 cases did not but 2 cases did recur after 7 months to 2 years' follow-up. Conclusions: Posterior nerve ending compression might not be uncommon in patients with dorsal wrist pain.
