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

Not Applicable

Completed

• Conditions: Fractures, Bone
• Interventions: Other: short-arm tube-type plaster fixation; Procedure: hamate hook removal; Procedure: microscrew internal fixation

• Registration Number: NCT03108716
• Lead Sponsor: Siping Central People's Hospital

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.

Arm && Interventions

Group	Intervention	Description
short-arm tube-type plaster fixation	short-arm tube-type plaster fixation	The patients were assigned to the short-arm tube-type plaster fixation (conservative treatment) (n=4).
hamate hook removal	hamate hook removal	The patients were assigned to hamate hook removal(n=13).
microscrew internal fixation	microscrew internal fixation	The patients were assigned to the microscrew internal fixation after open reduction (n=11).

Primary Outcome Measures

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

Secondary Outcome Measures

Name	Time	Method
Time of plaster fixation	At 6-18 months after surgery	To reflect fracture healing; the shorter the fixation time, the faster the healing
