One portal endoscopic release of the first extensor compartment in de Quervain's disease.

OBJECTIVES: We aimed to present preliminary result of one portal endoscopic assisted release of first dorsal compartment at wrist in a case series with de Quervain disease as a minimal invasive surgical method.

MATERIALS AND METHODS: The patients, who underwent an endoscopic-assisted release of the first extensor compartment for de Quervain's disease by same hand surgeon between 2015 and 2017, were retrospectively analyzed. Operative treatment was considered if the patients did not respond to non-operative treatment including oral anti-inflammatory medications, splinting, and steroid injection. Surgical release was recommended after minimum four months of unsuccesful non-operative treatment, including a steroid injection. 10 wrists were treated with one portal endoscopic assisted release. All patients were evaluated at an average of 16.1 months follow-up using visual analog scale (VAS) pain ratings and the Disabilities of Arm, Shoulder and Hand (DASH) score.

RESULTS: The mean operating time was 13.9 min (range, 10-21min). The mean VAS and DASH scores were improved from 8.2 to 1.9 and 70.51 to 2.81 respectively. No significant difference was found between operated and non-operated arms in postoperative pinch and strengths. Transient superficial radial nerve paresthesia (two wrists) and significant scar tenderness (one) were identified in three cases. There was no patient that complain of unsightly scar and tendon subluxation.

CONCLUSIONS: One portal endoscopic assisted release of the extensor compartment is an effective and safe minimal invasive procedure with similar complication rates reported previously in open and endoscopic procedures in patients with de Quervain's disease who are unresponsive to non-operative treatments.

LEVEL OF EVIDENCE: Level IV Therapeutic Study.
