Mechanical Strength of McLaughlin hip Nail—Plates Manufactured from 316 Lvm Stainless Steel: A Biomechanical Study of Unstable Trochanteric Fractures. V

Abstract

Mechanical testing of McLaughlin hip nail—plates manufactured from 316 LVM stainless steel was performed.

The mode of failure is described and the results are compared with previous tests of McLaughlin implants manufactured from Cobalt—Chromium—Molybdenum alloy. As there was no significant difference between these two products as regards the basic mechanical problem of failure of the nail-plate junction, it is recommended that the design be changed to make the implant suitable for internal fixation of unstable trochanteric fractures.
