Anatomic variaton of the first dorsal compartment in surgical treatment of DeQuervain disease.
Pak J Surg Jan ;35(1):59-62.

Objective: Anatomic variation of first dorsal compartment including variability of the abductor pollicis longus tendon, extensor pollicis brevis tendon and secondary osseo-fibrous canal help surgeons to treated DeQuervain's disease. Material and methods: 40 patients with DeQuervain's disease were included. All patients previously receive treatment either corticosteroid injection or surgical release of first dorsal compartment from different hospitals. All patients have still positive Finkelstein's test. In this study we re-explore, and particular look for the origin of the accessory tendon and of the presence or absence of a secondary osseo-fibrous canal within the first extensor compartment. Results: An accessory tendon of the abductor pollicis longus was found in (31)77% of wrists, though in only (5)12% wrists the accessory tendon found in a separate fibrous canal. In the remainder the abductor pollicis longus with all its accessory tendons of insertion occupied a common canal. A separate compartment for the extensor pollicis brevis was noted in (10)25% of cases. Conclusion: We conclude that knowledge of anatomic variation of first dorsal compartment prevent failure in the treatment of DeQuerain disease.
