[Fresh posterior luxation of the shoulder: irreducibility due to interposition of the long biceps. Apropos of 2 cases]. / Luxation postérieure récente de l'épaule: irréductibilité par interposition du long biceps. A propos de deux cas.

Two cases of irreducibility of recent posterior dislocation of the shoulder due to interposition of the long biceps are reported. The diagnostic procedures, the lesions noted during surgery and the therapeutic approach are described in the light of data found in the relevant literature.

[Osteoarthritis and tenosynovitis of the finger due to Mycobacterium intracellulare. A case report and review of the literature]. / Ostéo-arthrite et ténosynovite du doigt due à Mycobacterium intracellulare. Observation d'un cas et revue de la littérature.

The authors present one case of osteo-arthritis and tenosynovitis of the right forefinger due to Mycobacterium intracellulare, in a 61-year old woman. The treatment consists of a synovectomy of the finger's proximal interphalangeal joint and of the sheath of the flexor tendons and a drug regimen associating erythromycin and cotrimoxazole for 2 1/2 months. This therapy proves successful, as the patient is clinically cured. A literature review records 19 similar osteo-articular and peri-articular infections due to the Mycobacterium avium-intracellulare group, reported during these last 25 years.

[Traumatic etiology of Kienboeck's disease. (Perilunate subluxations and semilunate necrosis)]. / Etiologie traumatique de la maladie de Kienböck. (Luxations péri-lunariennes et nécrose du semi-lunaire).

The authors have studied the incidence of lunate necrosis in 110 perilunate dislocations. Twenty-one cases (19%) developed a necrosis. The classification into three types, according to the amount of damage to the perilunar ligaments, is of prognostic value. There is no risk of necrosis in type 1, 17% in type II, and 50% in type III. An associated fracture of the scaphoid does not modify the risk. In neglected lesions, reduction of the lunate dislocation should be attempted, even at a late date, the risk of necrosis then being 50%. Surgical reduction increases the risk of secondary necrosis to a greater extent than does orthopedic treatment, but it is generally use in the most complex cases too. The authors advocate a closed reduction with percutaneous pin fixation.
