[Comments on the accessory tubercle of the lumbar costiform apophysis (author's transl)]

The first results of a study of Luschka's accessory tubercle and Broca's styloid hypophysis, and especially of osteotendinitis which can arise from musculo-tendinous fatigue in this zone insertion. This osteotendinitis, whose radiological demonstration is difficult and rarely done, can possibly explain undoubtedly certain cases of localized lumbago.
