Posteromedial dislocation of the elbow is a rare entity even exceptional if associated with a lateral condylar fracture. Very few isolated cases are reported in the English literature. We report an additional case of a 14-year-old child admitted for elbow trauma during scholar sport and presented a posteromedial elbow dislocation associated with a fracture of the lateral humeral condyle.

Article Synopsis
  • Complex dorsal metacarpophalangeal joint (MCPJ) dislocations are rare injuries often caused by falls and primarily affect the index finger, occasionally accompanied by metacarpal fractures.
  • A case study discusses a 23-year-old man's complex MCPJ dislocation of the index finger along with a distal metacarpal fracture, treated successfully with surgery.
  • Early diagnosis through detailed imaging is crucial for effective treatment and improved long-term function, as these injuries can lead to complications like stiffness and osteoarthritis if not managed properly.

Coronal shear fractures of the distal humerus involving only the capitellum or the trochlea are rare injuries Their combination has rarely been described. Herein, we report the case of a 39-year-old man who presented with pain and total functional impotence in his right elbow following a fall; the clinical and radiological findings revealed a new entity in the coronal shear fractures of the distal humerus, which included a comminuted fracture of the capitellar and displaced separate trochlea in the same elbow. This fracture was treated surgically with a good outcome at the last follow-up.

At the elbow, the ulnar nerve has a peculiar anatomic location which explains its high vulnerability. We here report five cases of post-traumatic ulnar nerve instability with complete nerve dislocation in front of the epitrochlea. In the light of our experience and review of the literature, the pathogenic, diagnostic and therapeutic aspects of this pathology are reviewed.
