Strain pattern following surface replacement of the hip.
The aim is to compare the strain pattern in intact and resurfaced femurs using validated third-generation composite femurs and rosette strain gauges. The rosette strain gauges were applied to an intact and a resurfaced third-generation composite femur at three sites: the narrowest part of the lateral surface of the neck, the narrowest part of the medial surface of the neck, and the medial surfa...
متن کاملSurface Replacement of Hip Joint
Surface hip replacement more commonly known as hip resurfacing arthroplasty is a type of a hip replacement that is different to a total hip replacement. In a total hip replacement femoral head and neck are removed and a metal stem is inserted to the femoral shaft. In hip resurfacing articular surface is shaved and a metal cap (Fig 1) is inserted preserving most of the bone in femoral head and n...
متن کاملAlterations in femoral strain following hip resurfacing and total hip replacement.
Bone surface strains were measured in cadaver femora during loading prior to and after resurfacing of the hip and total hip replacement using an uncemented, tapered femoral component. In vitro loading simulated the single-leg stance phase during walking. Strains were measured on the medial and the lateral sides of the proximal aspect and the mid-diaphysis of the femur. Bone surface strains foll...
متن کاملSurface replacement arthroplasty of the hip.
The principle of hip joint resurfacing is replacement of diseased joint surfaces and simultaneous restoration of the normal anatomy and biomechanical function to the maximal degree possible. This concept offers several theoretical advantages over conventional total hip joint replacement and the clinical results in this series of 426 cases appears to confirm the value of both the method and the ...
متن کاملDislocation following total hip replacement.
An analysis of 142 dislocations from a multicentre study of 6774 total hip replacements is reported. The incidence of dislocation was 2.1 per cent. Patients with neuromuscular disorder, those in a confused mental state, and those undergoing revision operations are at special risk. The commonest surgical error, present in nearly half the patients, was placing the acetabular cup too vertically or...
