Summary
This report details the first case of fourth carpometacarpal joint dislocation without fractures. Early diagnosis via lateral wrist X-ray and prompt reduction are crucial for favorable outcomes in this rare injury.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Radiology
Background:
- Carpal injuries, particularly isolated carpometacarpal dislocations, are rare occurrences in orthopedic literature.
- Dislocations of the carpometacarpal joints without associated fractures are exceptionally uncommon.
Observation:
- This case report describes the first instance of a fourth carpometacarpal joint dislocation without any accompanying fractures.
- The diagnostic challenge is highlighted due to significant hand swelling, which can obscure the injury on initial examination.
Findings:
- A lateral radiograph of the wrist is essential for the accurate diagnosis of this specific injury when suspected.
- The absence of fractures in this carpometacarpal dislocation case is a unique finding.
Implications:
- Early recognition and prompt anatomical reduction are critical for achieving optimal long-term functional outcomes for patients.
- This case underscores the importance of maintaining a high index of suspicion for rare carpal injuries and utilizing appropriate imaging techniques.
