[Osteomalacia and giant cell tumor: a rare case]. / Ostéomalacie et tumeur a cellule géante: une entité rare.

BACKGROUND: Oncogenic octeomalacia is an unusual and rare clinicopathologic syndrome characterized by mesenchymal tumors that apparently produce osteomalacia and biochemical abnormalities consisting of hypophosphatemia and normocalcemia. AIM: We have investigated the mechanism by which a giant cell tumor of bone caused biopsy-proved osteomalacia in a 50-year-old woman. CASE REPORT: A 50-year-old woman presented with generalized bone and pelvicrural pain, associated with fatiguability and muscle weakness. The diagnosis of osteomalacia was retained, associated with a giant cell tumor. The coexistence of giant cell tumor of bone and osteomalacia suggested the diagnosis of oncogenic osteomalacia. Resolution of the biochemical abnormalities of the syndrome after tumor resection, established this diagnosis. CONCLUSION: oncogenic osteomalacia can be a form of vitamin-D-refractory osteomalacia due to altered vitamin D3 metabolism.

[About a short series of Swanson arthroplasty]. / A propos d'une courte série d'arthroplastie de swanson.

The authors report a series of 12 patients who underwent digital arthroplasty using a swanson implant. Six patients had the sequellae of an injured hand, and the other six patients had rheumatoid arthritis. The majority of patients were men with an average age of 33 years. The patients were examined again about 4 years later on average. The lateral stability of the operated finger was considered to be satisfactory in 11 cases. The mean movement gain was 40 degrees. There was no sign of silicone particle synovitis, because it was fixed arthroplasty.

[The sacrified of sacrifice day]. / Les sacrifies de la fete du sacrifice.

This prospective study was carried out in the plastic and reconstructive surgery department of Kassab's hospital in Tunis and the hospital of Monastir (Tunisa) during the sacrifice day (Aïd el kebir). The study involved 50 patients. Our purpose was to identify the injuries of the hand occurring during this religions festival. The average age of patients was 39 years with sex ratio of 1.17. All socials and occupational sectors were affected. The lesions concern the dorsal face of non dominant hand (72%) with a peak in the frequency for the thumb (40%) and the index (37%). Extensor system of the radial finger on the non dominant hand was the main delicate element witch is most exposed during such festival. The thumb is being worthy of special mention, for it is the most serious lesions (amputation 10%) The lesions of flexor tendons are generally associated with nerve and vascular injury. 46% of patients had to undergo surgery.

Anomalie musculaire et syndrome canalaire

There are tunnels syndromes secondary to a congestion of the tunnel by supernumerary muscles. We report 4 cases of carpal tunnel syndrome represented by a high insertion of a lombrical muscle, a supernumerary lombrical muscle, and two cases of an accessory palmaris longus. At the level of the tarsal tunnel, it was about a low muscular insertion of the tibialis posterior. Diagnosis can be suspected by specific operations and the treatment consists of the elimination of these "intruders" associated to neurolysis. Problem is to know if the supernumerary muscle is the cause or a simple witness of this canalar syndrome
