Hamate Hook Removal, Microscrew Internal Fixation and Plaster Fixation for the Treatment of Hamate Hook Fractures

Hamate Hook Removal, Microscrew Internal Fixation and Plaster Fixation for the Treatment of Hamate Hook Fractures: a Case Series

To compare the effects of hamate hook removal, microscrew internal fixation and plaster fixation on fracture healing, work, life, and exercise recovery in patients with hamate hook fractures by retrospective case analysis.

Study Overview

• Status: Completed
• Conditions: Fractures, Bone
• Intervention / Treatment: Procedure: hamate hook removal; Procedure: microscrew internal fixation; Other: short-arm tube-type plaster fixation

Detailed Description

Hamate hook fractures are rare, and mainly occur during sports activities. Its projection is often obscured by other carpal bone in conventional X-ray plain films, so hamate hook fractures are the most easily missed injury in hand surgery. As the incidence of such fractures is too small, it brings some difficulties in the clinical choice of correct and effective treatment. Currently, treatment programs of hamate hook fractures also are not consistent.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Fracture healing	Fracture healing was assessed using CT images or X-ray films at the wrist position holding a cup.	At 6-18 months after surgery

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Time of plaster fixation	To reflect fracture healing; the shorter the fixation time, the faster the healing	At 6-18 months after surgery
