BACKGROUND
Tendon entrapment of the first dorsal compartment of the wrist, the de Quervain disease, is a common cause of wrist and hand pain and disability. A group of 50 consecutive patients operated for the treatment of de Quervain disease from 2003 through 2006 were prospectively studied to determine the variation in the pattern of the first extensor compartment.
METHODS
Eighty-six percent of the patients were females, and 14% were males. In 80% of the cases the nondominant and in 20% the dominant hand was involved. These interesting findings may rule out the occupation's relation to de Quervain disease.
RESULTS
Our study revealed that the compartment is completely separated into two canals in 86% of the patients which was significantly higher than that reported in similar studies.
CONCLUSION
The existence of two separated compartments for abductor pollicis longus and extensor pollicis brevis tendons should be considered as a common finding during operation to prevent incomplete treatment and recurrence of the symptoms.
背景
腕部第一背侧腱鞘狭窄性腱鞘炎是腕部和手部疼痛及功能障碍的常见原因。对2003年至2006年连续接受手术治疗的50例桡骨茎突狭窄性腱鞘炎患者进行前瞻性研究，以确定第一伸肌间隙的形态变化。
方法
86%的患者为女性，14%为男性。80%的病例累及非优势手，20%累及优势手。这些有趣的发现可能排除了职业与桡骨茎突狭窄性腱鞘炎的关系。
结果
我们的研究显示，86%的患者腱鞘完全分为两个管，这一比例显著高于类似研究报道的比例。
结论
在手术过程中，应将拇长展肌和拇短伸肌腱存在两个分开的间隙视为常见情况，以防止治疗不彻底和症状复发。
