Uncemented custom femoral components in hip arthroplasty
BACKGROUND AND PURPOSE We have developed an individually designed, uncemented femoral component for achievement of improved strain distribution and fixation to the bone, to make uncemented stems more applicable in femurs of abnormal size and shape, and to improve the joint mechanics. Here we describe the design of the implant and present the results of a prospective clinical study with at least...
متن کاملCemented versus uncemented femoral components in the ring hip prosthesis.
A prospective, randomised and independently assessed trial of the Ring UPM total hip replacement showed that the quality of the early result was better if the femoral prosthesis was cemented than if it was not. More patients with cemented prostheses were painfree at four months (58% cemented:42% uncemented) and at one year (63% cemented:50% uncemented), but at two years pain relief was equal in...
متن کاملChallenges of Plate Fixation for Vancouver Type-C Fractures after a Well-Fixed Hip Arthroplasty Femoral Stem
The fixation of distal femoral fractures (Vancouver type-C fractures) following a well-fixed hip arthroplasty femoral stem has become a challenging issue for orthopedic surgeons due to the inter-prosthetic biomechanical effects such as negative, positive, and torsional strain. Surgeons have applied a range of constructs to overcome these difficulties. To minimize the risk of inter-prosthetic fr...
متن کاملRemoval of well-fixed components in femoral revision arthroplasty with controlled segmentation of the proximal femur
BACKGROUND The transfemoral and the extended trochanteric osteotomies are the most common osteotomies used in femoral revision, both when proximal or diaphyseal fixation of the new component has been decided. We present an alternative approach to the trochanteric osteotomies, most frequently used with distally fixated stems, to overcome their shortcomings of osteotomy migration and nonunion, bu...
متن کاملPrinciples of treatment for periprosthetic femoral shaft fractures around well-fixed total hip arthroplasty.
Postoperative periprosthetic femoral fractures around the stem of a total hip arthroplasty are increasing in frequency. To obtain optimal results, full appreciation of the clinical evaluation, classification, and modern management principles and techniques is required. Although periprosthetic femoral fracture associated with a loose stem requires complex revision arthroplasty, fractures associa...
