Summary
Idiopathic scapholunate dissociation, a wrist instability, can occur without trauma. Radiographs of the uninjured wrist are recommended before surgery for the injured hand.
Area of Science:
- Orthopedics
- Radiology
- Hand Surgery
Background:
- Scapholunate dissociation is a common wrist instability.
- It is typically associated with traumatic injuries.
- Characteristic radiographic signs are used for diagnosis.
Purpose of the Study:
- To report cases of idiopathic scapholunate dissociation.
- To highlight the importance of examining the contralateral wrist.
Main Methods:
- Review of radiologic findings in four cases.
- Identification of typical signs of scapholunate dissociation.
- Absence of trauma or symptoms in identified cases.
Main Results:
- Four cases of bilateral idiopathic scapholunate dissociation were identified.
- These cases presented with characteristic radiographic signs.
- No history of trauma or symptoms was reported.
Conclusions:
- Idiopathic scapholunate dissociation can occur without trauma.
- Radiographic examination of the uninjured wrist is crucial.
- This finding may influence surgical decision-making for wrist injuries.
