Abstract

|
Hamate bone fracture is an uncommon injury, accounting for 2% of all carpal bone fractures. The common treatment of choice for hamate bone fractures is conservative treatment or excision of the hamate fracture fragment. We devised a new procedure that utilizes dorsal percutaneous compression screws for internal fixation. This technique was performed on two patients with left hamate hook base fractures. Tolerable active joint movement of the left wrist and fingers was permitted the first day post-surgery. Radiographs were taken after surgery, at 3 months, and at 6 months to determine the degree of union. No remarkable ligament injuries or nerve injuries were observed. This technique proved to be a relatively simple procedure when compared to the existing procedure while enabling early wrist movement. By preserving soft tissue, this procedure maintained blood supply decreasing risks of non-union. These advantages make this technique a recommendable new procedure for hamate hook fractures.
