[Longevity factors in total trapezometacarpal prostheses].

We report the long term outcome of the trapeziometacarpal prosthesis in a personal series of 13 cases with a follow-up ranging from 12 to 17 years. This ball and socket prosthesis with a metal on polyethylene pairing is cemented. Several modifications were performed along the years: such as increased range of motion, better fit between the metacarpal medullary canal and the proximal part of the stem and addition of a versatile, intermediate component in order to re-establish length of the first ray.

[Intramedullary pinning for humeral diaphysis fractures. A minimal risk osteosynthesis. 82 cases].

Purpose: This study was designed to evaluate the complication rate of a novel intramedullary pinning technique described in 1988. After 10 years of clinical experience, it was possible to establish a significant difference in terms of healing delay compared with other fixation methods or conservative treatment.

Materials And Methods: During a 10-year period, a total of 82 fractures, mostly isolated, unstable fractures, were treated.

[Treatment of distal metaphyseal fractures of the tibia with the interlocking flexible osteosynthesis system].

Purpose: Accurate anatomic identification of distal metaphyseal fractures of the tibia is necessary when comparing the fixation ability of internal fixation devices. First, we have set the dimensions of the metaphyseal area. The purpose of this study was to evaluate the Interlocking Flexible Osteosynthesis system in properly selected distal metaphyseal fractures, not to be confused with distal shaft fractures.

[Long-term radiologic evolution of coral implanted in cancellous bone of the lower limb. Madreporic coral versus coral hydroxyapatite].

Purpose: The study aimed to compare two successive series of procedure using first pieces of natural madreporic coral, then coralline hydroxyapatite in traumatology. The goal of this work was to evaluate long term radiological features of absorption and influencing factors.

Material: Within six years, 65 pieces were used; only impaction articular fracture on the lateral tibial plateau (31) and calcaneum fractures (23) were included 21 cases completed inclusion criteria.

[Conditions for the consolidation of fractures of the femoral diaphysis after locked intramedullary flexible osteosynthesis].

Purpose Of The Study: We present here the clinical results achieved with locked intramedullary flexible osteosynthesis (LIFO) system in femoral fractures. The two major advantages of the device are its flexibility an ease of use.

Material And Methods: Over a period of 6 years, 42 patients were treated.
