[Post-traumatic arthritis of the wrist caused by an intra-articular foreign body]. / Arthrite post-traumatique du poignet par corps étranger intra-articulaire.

The authors report the case of a 12 year-old child presenting with post-traumatic arthritis of the wrist with intra-articular metallic foreign bodies. The trauma was initially considered to be benign, not operated on and forgotten by the child and its family. Excision of a synovial granuloma was followed by a favorable outcome.

[Failure of Dwyer's procedure in internal pes cavus in children. Physiopathological considerations and therapeutic deductions]. / Les échecs de l'opération de Dwyer dans le pied creux interne de l'enfant. Considérations physiopathologiques et déductions thérapeutiques.

The authors have performed 34 Dwyer's calcaneal osteotomies in children with pes cavus confined to the medial arch in non-paralytic lesions (poliomyelitis and spina bifida were excluded). In 12 cases it was associated with osteotomy of the 1st metatarsal or with plantar release. No arthrodeses were performed in these 34 cases. After an average follow-up of five years the results were doubtful: in 24 instances the deformity was the same or worse. In 21 cases a secondary operation was necessary. The authors considered that the Dwyer's procedure corrects only the varus of the heel which is a secondary deformity. They believe that, in pes cavus, there is a dynamic clawing of the toes in the swing phase of gait. This produces secondary deformities. In the sagittal plane there is a synergic or paralytic imbalance at the metatarso-phalangeal level leading to vertical displacement of the 1st metatarsal and deepening of the medial arch. In the frontal plane, this vertical displacement leads to an irreducible pronation of the forefoot with secondary varus of the heel. In the horizontal plane a lateral rotation of the talus results in varus of the calcaneum.

[Cancerized phagedenic ulcers. A study about 19 cases observed in Dakar "Hôpital Principal" from 1961 to 1976 (author's transl)]. / Ulcères phagédéniques cancérisés. A propos de 19 cas observes à l'Hôpital Principal de Dakar de 1961 a 1976.

Cancerization is the main complication of phagedenic ulcers which are frequent in tropical areas. The detection of the turn towards cancer is generally too late because of social and psychological conditions. Patients of this study were civil servants and had beneficial of a comparatively early detection. The clinical, radiological and pathological features are described and the importance of the control of lymph nodes is emphasized. The surgical tactic is discussed according to each situation but it must be as conservative as possible, even if the amputation is only delayed since lymphatic dissemination is late and amputation eminently dramatic in the african context.
