[Quadriceps fibrosis following intramuscular injections into the thigh: apropos of 92 cases at the Ignace Deen Central University Hospital in Conakry]. / Fibrose du quadriceps: séquelles d'injections intramusculaires de la cuisse a propos de 92 cas au C.H.U Ignace Deen de Conakry.

Analysis of 92 cases of quadriceps fibrosis following intramuscular injection into the thigh showed that the most affected age group was 3- to 7-year-old preschool children with a male predominance (68.7%). The most implicated drug (81.7% of cases) was quinine salts after of mean of 2 injections. Stiffness of the knee was the most outstanding clinical sign. In our series, the efficient technique for prompt functional recovery consisted of lengthening the quadriceps tendon by isolated "Z" plasty (56.5% of cases). Administration of drugs in oral, rectal or intravenous forms is the most effective means of prevention.
