Abstract

Hamate hook non-union is a relatively rare, but on the increase. We encountered a 25-year-old male baseball instructor with hamate hook non-union, and treated it with debridement of the fractured region and osteosynthesis using a break-away screw. Splint fixation was applied for three weeks after surgery, and active/passive range of motion exercises were actively performed thereafter. Bone union was noted three months after surgery. Transient ulnar paralysis resolved, and the patient could return to the same sports activity as that before injury six months after surgery. Since break-away screws are capable of loading a strong pressure on the fractured region and these screws can be inserted by preparing only a surgical field for guide wire insertion, requiring no soft tissue dissection to prepare a region for applying fixation materials, break-away screws are useful for the fixation of small bone fragments and osteosynthesis in a deep surgical field.
