Five to Ten-Year Results of the Birmingham Hip Resurfacing Implant in the U.S. 2018

Hip Resurfacing Information at Surfacehippy Posted on by

International surgeon series and registry data have demonstrated positive outcomes and long-term survival of the Birmingham Hip Resurfacing (BHR) implant. We report the 5 to 10-year results from a single center in the U.S.

…Conclusions: BHR demonstrated excellent survivorship and clinical outcomes at 5 to 10 years in selected patients. As compared with total hip arthroplasty, the use of the BHR may provide highly active patients with clinically important advantages in postoperative activity as well as a greater likelihood of remaining highly active. Continued follow-up is
necessary to validate long-term BHR outcomes…

…it may be beneficial to investigate the long-term outcome of hip resurfacings using metal-on-polyethylene in the 1980’s. We report the long-term survivorship and modes of failure of a cementless metal-on-polyethylene resurfacing.

Ongoing developments using the lessons learned from these previous generation components and utilizing modern low wear materials, e.g., cross-linked polyethylene, may lead to improved implants for future hip resurfacings.

Polymotion Hip Resurfacing Device by Mr. McMinn 2015

Hip Resurfacing Information at Surfacehippy Posted on by

The Polymotion Hip Resurfacing device is an allergy-free device that uses a 3mm-thick cup made with a material known as cross-linked polyethylene, one of the toughest plastics in existence.

Polymotion-Hip-Resurfacing-McMinn-2015

Traditional metal-on-metal hip resurfacing uses cobalt chromium alloy, explains Mr Derek McMinn, a consultant orthopaedic surgeon at BMI Edgbaston Hospital in Birmingham, who developed the new procedure.

‘Metal reactions vary in severity, but in the worst cases can lead to necrosis [death] of surrounding hip muscle and permanent disability for the patient,’ he said.

Another benefit of the capping procedure is that less bone is removed, in contrast to total hip … Read the rest

Brown, MD; Jared R. H. Foran, MD; Craig J. Della Valle, MD May 2013The purpose of this study was to compare total hip arthroplasty (THA) and hip resurfacing arthroplasty (HRA) with regard to the amount of acetabular bone stock removed and the ability to restore leg length and offset. Anteroposterior pelvis radiographs of 153 consecutive THAs and 84 consecutive HRAs were compared. Excluded patients were those with prior hip surgery, those in which a best-fit circle could not be adequately matched to the femoral head, and those with preoperative radiographic findings that precluded consideration for HRA… Read the rest

Metal-on-Metal Hip Resurfacing: The Effect of Component Position

Link 2006D.H. Williams; U. Masood; and M.N. Norton Royal Cornwall Hospital, Truro, Cornwall TR1 3LJ, UK.

Decreased head-neck ratio diameter and component malposition in total hip arthroplasty are factors known to result in impingement, increased rates of dislocation, wear and failure. In addition to these complications, impingement of the femoral neck on the acetabular component of a hip resurfacing may result in femoral neck fracture and loosening of the acetabular component. Little is known regarding the optimum femoral and acetabular hip resurfacing component position to avoid impingement.

In the first part of this study we analyzed the radiographic component

Larger cups and optimal positioning produced lowest ion levels by David Langton

Larger cups and optimal positioning produced lowest ion levels and wear

In a review of 585 blood serum evaluations following hip resurfacing, only femoral size and cup inclination were found to have an effect on ion levels, according a study by orthopedic investigators.

The findings were presented at the 2010 Annual Meeting of the American Academy of Orthopaedic Surgeons.

David J. Langton, MRCS, and his colleagues also found that the size of the coverage angle of the acetabular component contributed significantly to its tolerance of suboptimal positioning.

“Larger joints, it must be emphasized, tolerated suboptimal cup position,” he said. “This

In 2009, the Oxford Group reported a 1.8% rate of revision for pseudotumours in a series of 1419 hip resurfacings performed by multiple surgeons within a mean 4 year (0-9 years) time period and a 6% Kaplan-Meier failure rate for pseudotumour by 8 years. We were surprised by this high rate of failure due to a primary inflammatory reaction to metal bearings

INTRODUCTION:

Hip resurfacing has been proposed as a suitable procedure for young, active patients. Given the concerns with metal-on-metal bearings, and the recall or withdrawal of certain devices, it is appropriate to review our results using a resurfacing device with a relatively good clinical record.

Abstract

INTRODUCTION: Metal-on-metal hip resurfacing has provided an alternative to standard total hip arthroplasty in younger, more active patients. However, detractors argue that many of the benefits of resurfacing can be obtained with the use of larger femoral heads. The purported advantages of the resurfacing procedure include preservation of femoral bone stock, increased range of motion, decreased dislocation rate, excellent performance in high-activity patients, and a potentially easier revision than total hip arthroplasty. The purpose of this study
