Closed medial subtalar dislocation: A case report and literature review.

Subtalar dislocation is characterized by simultaneous dislocation of the subtalar (talocalcaneal) and talonavicular joints, hence the name talocalcaneonavicular. These lesions can be grouped into four distinct categories: anterior and posterior, which are exceptional, lateral and medial. Medial subtalar dislocations are more frequent, are due to low-energy trauma and generally have good functional results. Anatomical reduction and stabilization of the subtalar joint and optimal management of all associated foot injuries are the key to good results.

Isolated dorsal dislocation of the distal radioulnar joint: A case report.

Isolated acute dislocation of the distal radioulnar joint is a rare lesion, and in 50 % of cases goes unrecognized; it may be palmar or dorsal. Its diagnosis is suspected when the wrist is traumatic, painful, with limited pronosupination and no fracture on radiological examination. Treatment is aimed at preventing the development of chronic instability and/or arthrosis, and consists of reduction followed by immobilization.
