Abstract:
Authors report the results of a series of osteosynthesis by the gamma nail performed on an ordinary radio-transparent operating table. The aims were to highlight the tricks of our technique for its realization, and to analyze the results obtained. 53 osteosynthesis with gamma-2 nails were performed on a regular, radio-transparent table in 31 females and 22 males. The mean series age was 54.3 years old. According to AO Classification 16 fractures were of type 31A1, 24 of type 31A2, and 13 of type 31A3. We analyzed the following data: epidemiological parameters (etiology, ASA score); intervention and scopic irradiation duration; the qualities of reduction and osteosynthesis; the dimensions of the implant used; peroperative and postoperative complications; the need for blood transfusion; stand up and consolidation . Fractures were secondary to a fall from height (32 cases), a road accident (17 cases), and a pathological fracture (04 cases). The surgery duration average was 42 minutes and that of the irradiation due to the scopy varied between 50 and 75 seconds. The nail with 130 0 angulation and the 90mm cephalic screw were the most used. Osteosynthesis was correct in 90% of cases. We deplored 15% reduction defects and eight cases of technical error. The early complications were 02 cases of secondary diaphyseal fracture 05 cases of hematoma, 01 case of superficial sepsis. No case of blood transfusion was necessary. Consolidation was achieved between 10 to 12 weeks. The mechanical complications were: sweep of the cephalic screw (1 case), vicious callus (3 cases). Parker's mean score was 7.8 points at 6 months postoperatively. The results of this osteosynthesis on a radio-transparent ordinary table gave us encouraging radiological and functional results.
