Abstract

Introduction Hook of hamate fractures are rare. The best treatment option is a source of debate; it ranges from conservative to surgical techniques, including resection of the hook or a volar approach followed by internal fixation. These techniques are not exempt from risk. Minimal invasive fixation using a dorsal percutaneous approach and a headless, cannulated mini screw is another option, although not commonly considered. We present a case series of patients who underwent this surgical technique.

Methods This is a retrospective review of four patients with nondisplaced hook of hamate fractures treated with dorsal percutaneous fixation. The evaluation included symptoms, physical examination, and radiological (radiographs, magnetic resonance imaging [MRI], and computed tomography [CT]) findings, as well as pre and postoperative strength (determined with a Jamar (JLW Instruments, Chicago, USA) hydraulic dynamometer) and quick disabilities of the arm, shoulder and hand (QuickDASH) scores.

Results The union rate was 100% with no associated complications. All patients resumed their preinjury activities 3 months after the surgery and reported they would undergo surgery again if needed.

Conclusion This retrospective study shows that safe treatment of nondisplaced hook of hamate fractures with percutaneous dorsal fixation is feasible, with excellent clinical outcomes. In any case, our sample is limited, and further studies are required.
