Knowledge of anatomic landmarks for the first dorsal compartment can assist clinicians with management of de Quervain's disease. The radial styloid, the scaphoid tubercle, and Lister's tubercle can be used as superficial landmarks for the first dorsal compartment.
Thirty-two cadaveric wrists were dissected, and measurements were taken from the predetermined landmarks to the extensor retinaculum. The compartments were also inspected for variability of the abductor pollicis longus tendon and intracompartmental septations.
The average length of the extensor retinaculum from its proximal to distal extent measured approximately 2.2 cm. The distal aspect of the radial styloid was 0.3 cm distal to the distal aspect of the extensor retinaculum, and the distance between the distal aspect of the extensor retinaculum and the APL-Lister's-Scaphoid juncture was approximately 0.5 cm. A separate compartment for the extensor pollicis brevis was noted in 35% of the specimens. The abductor pollicis longus tendon demonstrated great variability with 1, 2, 3, or 4 slips in 9%, 30%, 43%, or 26% of the specimens, respectively.
The superficial bony prominences of the radial wrist can be used reliably as anatomic landmarks for the first dorsal compartment.
了解第一背侧腱鞘的解剖标志有助于临床医生对桡骨茎突狭窄性腱鞘炎进行治疗。桡骨茎突、舟骨结节和李斯特结节可作为第一背侧腱鞘的浅表标志。
解剖32具尸体手腕，测量从预定标志到伸肌支持带的距离。还检查了腱鞘，观察拇长展肌腱的变异性和腱鞘内的分隔情况。
伸肌支持带从近端到远端的平均长度约为2.2厘米。桡骨茎突远端比伸肌支持带远端远0.3厘米，伸肌支持带远端与拇长展肌-李斯特结节-舟骨交界处的距离约为0.5厘米。35%的标本中可见单独的拇短伸肌腱鞘。拇长展肌腱变异性很大，分别有9%、30%、43%或26%的标本出现1、2、3或4条肌腱束。
桡腕关节的浅表骨性突起可可靠地用作第一背侧腱鞘的解剖标志。
