Traumatic dorsoradial dislocation of the trapezium
The Journal of Hand Surgery
|March 1, 1987
Summary
Traumatic dorsoradial trapezium dislocation is rare. Open reduction with Kirschner wire fixation is recommended for this first metacarpal injury.
Area of Science:
- Hand surgery
- Orthopedic trauma
- Wrist biomechanics
Background:
- Traumatic dorsoradial dislocation of the trapezium is an uncommon injury.
- Few cases have been documented in medical literature.
Observation:
- The study presents two new cases of traumatic dorsoradial trapezium dislocation.
- Analysis suggests forced flexion of the first metacarpal as the primary mechanism.
Findings:
- Open reduction and Kirschner wire fixation are proposed as the preferred treatment.
- This surgical approach aims to restore joint stability and function.
Implications:
- This management strategy may improve outcomes for patients with this rare injury.
- Alternative treatments like excision or arthrodesis are considered for cases with poor results.
