title: Multiple etiologies of trigger wrist.
abstract: BACKGROUND
  Trigger wrist, a relatively unusual condition, is a triggering at the wrist produced by wrist or finger motion. The clinical manifestations and surgical results of trigger wrist with multiple etiologies were evaluated.
  
  
  METHODS
  From October 2008 to December 2012, this study retrospectively reviewed 15 patients diagnosed with trigger wrist. The patients comprised six men and nine women with a mean age of 44.8 years (range, 29-86 years). The mean follow-up period was 16.2 months (range, 11-30 months).
  
  
  RESULTS
  The causes of trigger wrist were an anomalous muscle belly of the flexor digitorum superficialis (n = 5), severe tenosynovitis of the flexor tendon (n = 4), fibroma around the flexor tendon sheath (n = 2), a rheumatoid nodule (n = 1), both anomalous muscle belly and tenosynovitis (n = 1), a ganglion (n = 1), and pigmented villonodular synovitis (n = 1). Mild-to-moderate symptoms of median neuropathy without thenar muscle atrophy were present in all patients. Postoperatively, all patients recovered well with resolution of median nerve symptoms, and the wrist triggering was absent.
  
  
  CONCLUSIONS
  Trigger wrist is a relatively rare condition compared with trigger finger, which is the most common disorder of the hand. To avoid inadequate and ineffective treatment of patients with trigger wrist, careful examination and proper diagnosis are vital.
  
  
  METHODS
  Therapeutic/IV.
