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.

Tuberculosis of navicular bone: An exceptional localization of osteoarticular tuberculosis.

Osteoarticular tuberculosis (OAT) is defined by the set of pathological manifestations secondary to the attacks of osteoarticular structures of the locomotor system by the Bacillus of Koch (BK). We report a case of tuberculosis of the navicular bone, which is a rare location of OAT, on a female patient who consulted for chronic pain (mixed appearance) evolving for more than 7 years and for whom we realized a radiological assessment based on standard radiography and magnetic resonance imaging and a biological assessment. The foot is rarely involved, accounting for about 10% of cases of osteoarticular tuberculosis.

The induced membrane technique: A therapeutic option for managing bone defects in the upper extremity: Case series for 7 patients.

Introduction: The reconstruction of bone defects of tumoral, infectious or traumatic origin of the limbs remains a major therapeutic challenge for the orthopedic surgeon and the patient, in terms of anatomical and functional results.

Cases Presentation: We report the case of 7 patients who underwent induced membrane bone reconstruction of the upper extremity, 5 patients with initial injury to the forearm, and 2 of our patients, to the humerus. In terms of function, the range of prono-supination was 125°, the range of wrist flexion-extension was 165°, and the range of elbow mobility was 170°.
