[Stable osteosynthesis of unstable per- and subtrochanteric femoral fractures using the 130 degrees double-T plate].
Operative treatment of instable inter- and subtrochanteric fractures with a new 130 degrees-double-T-plate allowed, in spite of high-risk patients (age x=81 to 84 years, multimorbidity 92%), full maximum load by the third day after operation and a shorter time of hospitalization of 22.5 days. Mortality rate came up to 9%. Load experiments showed that the double-T-profiled 130 degrees-plate with increased lateral moment of resistance could support a weight five times greater than that supported by 130 degrees-implants with transversal blades or DHS-screws. In addition, the double-T (I-Beam) profiled 130 degrees-angled-plate had a resistance to bending two-and-a-half times greater than the hip compression screw from Pohl and has demonstrated its marked clinical success. Follow-up made in 256 patients for 6 to 66 months after double-T-plate osteosynthesis showed good results in 82.2% of the patients satisfied with the outcome of surgery, 13.9% needed two crutches and found the result achieved poor. Only 3.9% of all patients achieved no walking capability.
