Abstract
1. Operative treatment of instable inter- and subtrochanteric fractures with a new 130 degrees double-T plate allowed, in spite of high-risk patients (age mean = 85 years, multimorbidity approximately 92%), full maximum stress by the third day after the operation and a shorter time of hospitalisation of 22.5 days. Lethality was 12.2%. - 2. 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, and had a resistance to bending two-and-a-half times greater than hip compression screws. In an 'intertrochanteric' position the plate could carry 3000 N and in a 'subtrochanteric' position 1000 N without permanent deformity. - 3. A review was carried out in 62.6% of the patients 6-32 months after double-T-plate osteosynthesis. Acceptable results were revealed in 80.7%. Of the 98 patients reviewed 44% had complete freedom of movement, 34.6% walked with a stick, 15.4% required crutches and 6% were unable to walk.
