| Popis: | Fracture of the femoral neck is a common injury of the human skeleton. High rate of postoperative complications induces to the search of optimum osteosynthesis technique. Treatment results for 259 patients (182 females, 77 males, mean age 72 years) with femoral neck fractures were analyzed. In study group (n=114) a dynamic derotation osteosyntesis and in control group (n=145) - DHS, a bundle of V-shaped curved pins, cannulated screws were used. Mathematic modelling of bone-implant system in different variants of derotation fixator screws position under load was performed. Use of dynamic derotation constructions in Garden 1 and Garden 2 femoral neck fractures ensured a consolidation of fractures in all clinical observations, in Garden 3 fractures - in 46.4%. Early dosage weight bearing not exceeding 60% of the body weight did not result in either fragments displacement or raise of the rate of femoral head avascular necrosis development. In patients under 60 years it is preferably to use dynamic derotation constructions with 4 screws placed in the femoral neck. |
