Die Belastbarkeitsgrenze verschiedener Osteosynthesen pertrochanterer Oberschenkelfrakturen

Abstract

To obtain valid information on stress tolerance of pertrochanteric fractures, we exposed three different methods of osteosyntheses to dynamical stress and the results were compared. The methods of osteosyntheses were application of a 130 degrees angle plate, performing an adjoining osteosynthesis with bone cement or using cephalocondylar nails. The measurements in connection with photographical and roentgenological examinations of osteosyntheses under stress gave the following results: Compared with the other methods treatment with condylar nails gave equal results in static behaviour yet was clearly superior in its dynamic reaction.

Stability of osteosynthesis in trochanteric fractures: Comparison of three fixation devices in cadavers

“…In these tests the important interplay between bone and implant was not considered. In order to compare the performance of osteosynthesis when stabilizing a fracture, studies of fixed stable, as well as unstable, trochanteric fractures in cadaver femora have been made (Kaufer et al 1974, Martinek et al 1976, Sauer et al 1977). In most cases the load applied on the bone-implant preparation was either static or uniaxial dynamic.…”

Pertrochanteric Fractures of the Femur:A Comparative Study of Internal Fixation with Angle Nail-Plates and Flexible Condylar Nails

“…In young people anatomic reduction and fracture fixation, together with a longer period of nonweight-bearing, essentially reduces the risk of a posttraumatic coxarthrosis and is therefore often preferred (Martinek et al 1976).…”
