Corrective Fifth Metacarpal Neck Osteotomy and Intramedullary Screw Fixation Technique: Technique and Case Report

Abstract

Malunion of metacarpal fractures can result in severe functional and esthetic impairment to the patient, thus requiring surgical correction. Traditionally, the fixation methods most commonly used for these fractures are the Kirschner wires or the plates and screws. However, one of the options for the fixation of metacarpal fractures is intramedullary fixation with a headless screw. This minimally invasive method can also be used for corrective metacarpal osteotomies. It has the advantages of being a minimally invasive technique and allowing the early range of motion. This minimally invasive method can also be used to stabilize the corrective metacarpal osteotomies for malunion. This case report presents a minimally invasive technique for corrective dorsal metacarpal osteotomy and fixation with a headless intramedullary screw. This alternative fixation method has the advantage of low damage to soft tissues and good functional outcomes.

“…6). [9][10][11] The disadvantage is the potential risk of rotational deviation by the screw, which is minimized by a cotton soft-spica. There is also the difficulty of screw removal in the event of breakage or bending of the screw due to a secondary injury or bone overgrowth, making screw extraction challenging.…”
