De Quervain disease is the stenosing tenosynovitis of the first extensor compartment of the wrist. It is diagnosed with a history of pain at the radial aspect of the wrist and a positive Finkelstein test. Although anatomic variations, such as a septum within the compartment, are considered as risk factors, bony anatomy of distal radius and its correlation with the septa are studied scarcely in the literature.
We dissected 50 wrists of 26 cadavers. Presence and location of a septum within the compartment was evaluated. We also observed the grooves at distal radius and their relation to the first extensor compartment and its content.
The septum was absent in 23 wrists (46%). A septum was present in 27 (54%) wrists (15 incomplete 30%, 12 complete 24%). At the distal radius, we classified three radial groove types as Type 1 on 28 (56%), Type 2 on 14 (28%), and as Type 3 on 8 (16%) wrists. There was a statistically significant relation between complete type of septa and Type 1 grooves (p = 0.002).
We investigated the bony structures of the compartment along with its content and we believe our results might guide clinicians who diagnose and treat de Quervain tenosynovitis.
桡骨茎突狭窄性腱鞘炎是腕部第一伸肌支持带的狭窄性腱鞘炎。根据腕部桡侧疼痛病史及芬克斯坦试验阳性进行诊断。尽管诸如支持带内的隔膜等解剖变异被视为危险因素，但关于桡骨远端的骨骼解剖及其与隔膜的相关性，在文献中鲜有研究。
我们解剖了26具尸体的50只手腕。评估支持带内隔膜的存在情况和位置。我们还观察了桡骨远端的沟及其与第一伸肌支持带及其内容物的关系。
23只手腕（46%）无隔膜。27只手腕（54%）有隔膜（15只不完全隔膜占30%，12只完全隔膜占24%）。在桡骨远端，我们将三种桡侧沟类型分类为：28只手腕（56%）为1型，14只手腕（28%）为2型，8只手腕（16%）为3型。完全隔膜类型与1型沟之间存在统计学显著关系（p = 0.002）。
我们研究了支持带的骨骼结构及其内容物，我们相信我们的结果可能会对诊断和治疗桡骨茎突狭窄性腱鞘炎的临床医生有所指导。
