ABSTRACT
PURPOSE:
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.METHODS:
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.RESULTS:
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).CONCLUSION:
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.
