|January 1, 1981
Summary
De Quervains dislocation fractures often result in scaphoid nonunion after closed reduction. Open reduction and internal fixation significantly improve healing rates, reducing pseudarthrosis from 59% to 16%.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Hand Surgery
Background:
- De Quervains dislocation fractures frequently lead to scaphoid bone pseudarthrosis after closed reduction.
- Previous reports indicate a high rate of nonunion (59%) following conservative management.
Purpose of the Study:
- To evaluate the efficacy of open reduction and internal fixation for scaphoid fractures associated with De Quervains dislocation.
- To compare the pseudarthrosis rates between conservative and surgical interventions.
Main Methods:
- Review of cases involving De Quervains dislocation fractures with scaphoid involvement.
- Comparison of outcomes between patients treated with closed reduction versus open reduction and screwing.
- Analysis of pseudarthrosis rates in both treatment groups.
Main Results:
- Closed reduction of perilunar dislocations requires exact fragment adaptation for fracture healing.
- Open reduction and screwing of the scaphoid fracture is indicated when conservative means fail.
- Surgical intervention resulted in a significantly lower pseudarthrosis rate of 16%.
Conclusions:
- Open reduction and internal fixation provide superior results for scaphoid fractures in De Quervains dislocations.
- Surgical management is crucial for achieving optimal healing and minimizing nonunion rates.
- Precise fragment alignment is paramount for successful scaphoid fracture healing.
