[The tensile strength of various osteosyntheses of the unstable major trochanter. An experimental study]. / Die Zugfestigkeit unterschiedlicher Osteosynthesen des instabilen Trochanter major. Eine experimentelle Studie.

ABSTRACT

Eight of the prevalent techniques for performing osteosynthesis of the greater trochanter were compared to determine the stability of each. In an experimental setup, the reaction to deformation in the osteotomy cleft as a result of increasing tension stress was determined and analyzed in the femora of 22 corpses. The strain tolerance was not only dependent on the particular form of osteosynthesis but also on the technical details. Our study on the reaction to deformation showed that even low levels of tension stress caused significant dislocation in the osteyomy cleft despite an intact osteosynthesis. The results permit conclusions to be drawn that will contribute to the improvement of surgical technical details as well as postoperative treatment.
