Simultaneous dislocation of the hamate and pisiform: a case report.
The Journal of Hand Surgery
|January 1, 1985
Summary
A fall caused a rare simultaneous dislocation of the hamate and pisiform bones in a patient's wrist. Surgical treatment involving hamate reduction and pisiform excision led to an excellent outcome.
Area of Science:
- Orthopedic surgery
- Traumatology
- Hand and wrist surgery
Background:
- Wrist injuries are common, but combined dislocations of the hamate and pisiform are exceptionally rare.
- Understanding the biomechanics of such injuries is crucial for effective treatment.
Observation:
- A 27-year-old male patient presented with a fall onto a flexed wrist.
- Radiographic and clinical examination revealed a posterior hamate dislocation and a lateral pisiform dislocation.
- The injury mechanism involved a high-energy impact to the dorsum of a flexed wrist.
Findings:
- Open reduction and internal fixation were performed for the posteriorly dislocated hamate.
- The laterally dislocated pisiform was surgically excised due to its instability and irreducibility.
- Histopathological examination of the excised pisiform is pending.
Implications:
- This case highlights a unique pattern of carpal instability requiring specific surgical management.
- Pisiform excision can be a viable option for managing irreducible or unstable pisiform dislocations.
- Further research into the long-term outcomes of combined hamate and pisiform dislocations is warranted.
