Subchondral fractures of the femoral head: a review of seven cases.

Objective: To describe the main characteristics of subchondral fractures of the femoral head.

Case-reports: The seven patients, five women and two men, with a mean age of 50 years (37-76 years), presented with mechanical pain in the groin. Bone loss was the main risk factor.

[Initial manifestations and late diagnosis in chronic atrophic polychondritis: apropos of a series of 15 patients].

An auricular or nasal chondritis or a saddle nose deformity are the initial manifestation in half of cases of relapsing polychondritis; the other initial manifestations are various and less evocative; polyarthritis, laryngo-tracheal symptoms, episcleritis which delay the diagnosis. From 15 cases of relapsing polychondritis, the diagnosis time from the first symptom are studied; this one is long, about 3 years and 6 months (from 3 months to 17 years) in 13/15 of the cases even if the first manifestation is typical (external chondritis). In two cases only, the diagnosis was established after the first attack.
