Purpose:To evaluate the treatment results of fragment excision of the hamate hook nonunion.
Material and Methods : Nine patients operated for hamate hook nonunion were reviewed retrospectively, and were clinically assessed for pain, range of motion, tingling sensation, and grip strength postoperatively.
Results: The initial symptoms were pain (3 cases), tingling sensation (3 cases), 5th DIP joint flexion LOM (2 cases), and pain and accompanying LOM in 5th DIP joint flexion (1 case). The causes of injuries seemed to be mainly associated with sports activities. Time from initial symptom to diagnosis was averaged 15 months (2 months-5 years), and confirmative image was plain x-ray (one case), carpal tunnel view (six cases), and CT scan (two cases). All patients underwent fragment excision, and in three patients with accompanying carpal tunnel syndrome, transverse carpal ligament release was performed accordingly. In three other patients complicated with 5th FDP rupture, tenorrhaphy was performed in two cases, and tendon transfer was performed in the other case. Eight patients showed excellent clinical results one year postoperatively, but one patient complained of transient tingling sensation on the 4th and 5th fingers.
Conclusion: Hamate hook excision after nonunion showed excellent clinical results in one year postoperative follow-up.
