Case:
A 32-year-old man with Ehlers-Danlos syndrome (EDS) fell while snowboarding and injured his right elbow. Radiography revealed a posterior dislocation of the elbow and a proximal radioulnar joint dislocation. A diagnosis of transverse divergent dislocation of the elbow was established. Open reduction and repair of the annular ligament, anterior oblique ligament, and capsule was performed with good clinical results.
Conclusion:
This is the first report of divergent dislocation of the elbow in an adult with EDS. Dislocation occurred without a fracture that required open reduction and internal fixation. The presence of soft-tissue fragility, hyperextension, and joint laxity peculiar to EDS are likely contributing factors to this phenomenon.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
