De Quervain disease (DD) is a mechanical tenosynovitis due to volume insufficiency between abductor pollicis longus (APL), extensor pollicis brevis (EPB) and their tunnel.
During this period, a surgeon examined patients with simple De Quervain disease confirmed by clinical examinations.
3) In a study conducted by Zarin and Ahmad from 2001 to 2002, patients with De Quervain disease who did not respond to conservative treatment were operated and followed up for a minimum period of 3 months to assess their clinical outcome of procedure.
Le Viet and Lantieri reported 62 cases of De Quervain disease treated from 1983 to 1990 by the same surgeon and they found that transverse incision causes less disfavor scars.
A longitudinal incision in surgical treatment of De Quervain disease has many advantages including; easy finding of compartment variations and superficial branches of radial nerve and prevention of palmar tendon subluxation as a result of more dorsal release of the compartment sheath.
presented the long-term results of De Quervain disease surgery from 1988 to 1998.
Although, De Quervain disease surgery is effective in the treatment of symptoms in most patients, the longitudinal incision results in poor wound healing and damage to the terminal branches of the radial nerve.
Overall, longitudinal incision can be recommended for surgical treatment of De Quervain disease.
The anatomy ofthe variations ofthe EDM is important for successful treatment of De Quervain disease, where the tenosynovectomy has to be performed.
Anatomical knowledge of the extensor tendons is important for successful tenosynovectomy in the treatment of De Quervain disease (7).
