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

Study Overview
=================
Brief Summary
-----------------
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.

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 |
