Surgical excision of ununited hook of hamate fractures via the carpal tunnel approach

Abstract

Introduction: Direct excision of a symptomatic ununited hook of hamate fracture is the gold standard, most frequently via a Guyon space approach. The open carpal tunnel approach is another option, which has not previously been commonly considered and not reported in a peer review journal. Our study aims to highlight the carpal tunnel approach as a successful technique in a consecutive series of ununited hook of hamate fractures.

Patients and methods: Seven patients (all male and mean age 30.7 years) were reviewed with symptomatic ununited fractures following a period of cast immobilization. All the patients operated on underwent excision of the hook of hamate fragment via the open carpal tunnel approach.

Results: All patients successfully returned to their pre-injury level of functioning after 8-12 weeks and there were no complications.

Conclusions: Our study highlights the open carpal tunnel approach as a successful technique for open excision of symptomatic ununited hook of hamate fractures, because of its familiarity, ease of performance, excellent visualization and low morbidity. Level of Evidence IV Case Series.
