Gait after Birmingham Hip Resurfacing an age-matched controlled prospective studyAnatole V. Wiik, Rhiannon LambkinJustin P. CobbPublished Online: https://doi.org/10.1302/0301-620X.101B11.BJJ-2019-0383.R1
ConclusionPatients undergoing HRA improved their preoperative gait pattern of a significant limp to a symmetrical gait at high speeds and on inclines, almost indistinguishable from normal controls. HRA with an approved device offers substantial functional gains, almost indistinguishable from healthy controls.

The aims of this study were to investigate the following questions: (I) what are the mortality rates in patients age 55 years and younger who underwent a hip resurfacing arthroplasty (HRA) versus a standard total hip arthroplasty (THA)? (II) is the type of operation independently associated with mortality?
We have demonstrated that patients age 55 and younger who undergo HRA have a … Read the rest
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.

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 position of 131 consecutive hip resurfacings. In the second part the effect of three component variables on the range of motion to impingement were analyzed
Joseph Daniel, Director of Research at the McMinn Center in Birmingham UK, talks about the 10 year survival of double heat-treated resurfacings from 1996 and the effect that these heat treatments had on this series of hip resurfacings.

Hip Resurfacing With the Biomet Hybrid ReCap-Magnum System: 7-Year Results by Dr. Gross & Fei Liu 2012
|Gross TP, Liu F. – Midlands Orthopaedics, P.A., Columbia, SC. Abstract The purpose of this study was to report our clinical outcome of a large series of metal-on-metal hip resurfacing arthroplasty (HRA) using the hybrid Biomet ReCap-Magnum system. This is a single-designer surgeon series with an average of 5 ± 1 years. Seven hundred forty consecutive hybrid HRAs were performed in 653 patients. Kaplan-Meier survivorship with any revision as an end point was 96.4% at 7 years. Twenty-five (3.4%) cases were revised: 8 due to acetabular component loosening, 6 due to femoral neck facture, 4 due to failure of femoral component fixation, 2 due to deep infection, 2|
|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 must be taken into account in all analyses.”
Using routinely obtained blood serum metal ion levels from patients under the care of the

|Incidence of Adverse Wear Reactions in Hip Resurfacing Arthroplasty: A Comparison with the Oxford StudyThomas P. Gross, MD (d), Fei Liu, PhD (d) Midlands Orthopaedics, Columbia, SCIntroduction|
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 (pseudotumour) and we therefore wanted to evaluate our database for the incidence of failure we experienced due to pseudotumours.

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. As our experience and understanding of these bearings grew, we now describe changes to our preferred component position, and have used additional imaging to narrow our indications for this procedure, … Read the rest
