Summary
Rotatory dislocation of the second carpometacarpal joint is rare and can be complicated by tendon entrapment. This case highlights a unique presentation and a novel roentgenographic technique for evaluation.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Radiology
Background:
- Carpometacarpal (CMC) joint dislocations are uncommon injuries.
- Isolated dorsal and rotatory dislocations of the second CMC joint are particularly rare.
Observation:
- A case of rotatory dislocation of the second CMC joint is presented.
- Reduction of the dislocation was impeded by the extensor carpi radialis longus tendon entrapped within the joint.
Findings:
- The study details a rare instance of rotatory dislocation at the second CMC joint.
- Successful reduction was achieved despite the tendon entrapment.
- A specific roentgenographic technique for assessing CMC joint dislocations is described.
Implications:
- This case expands the understanding of potential complications in CMC joint dislocations.
- The described roentgenographic technique may aid in the diagnosis and management of similar injuries.
- Highlights the importance of considering tendon entrapment in irreducible dislocations.
