Multiple etiologies of trigger wrist.

Area of Science:

• Orthopedics
• Hand Surgery
• Musculoskeletal Disorders

Background:

• Trigger wrist is an uncommon condition characterized by triggering during wrist or finger movement.
• It presents distinct clinical manifestations and requires evaluation of various etiologies.

Purpose of the Study:

• To evaluate the clinical manifestations and surgical outcomes of trigger wrist.
• To identify the diverse causes contributing to trigger wrist.

Main Methods:

• Retrospective review of 15 patients diagnosed with trigger wrist between October 2008 and December 2012.
• Analysis of patient demographics, follow-up periods, and surgical results.

Main Results:

• Common causes included anomalous flexor digitorum superficialis muscle belly (n=5) and flexor tenosynovitis (n=4).
• All patients experienced mild-to-moderate median neuropathy symptoms.
• Postoperative recovery was excellent, with resolution of triggering and median nerve symptoms.

Conclusions:

• Trigger wrist is rare compared to trigger finger.
• Accurate diagnosis and careful examination are crucial for effective treatment of trigger wrist.
