Gait after Birmingham Hip Resurfacing an age-matched controlled prospective study
Anatole V. Wiik, Rhiannon LambkinJustin P. CobbPublished Online: https://doi.org/10.1302/0301-620X.101B11.BJJ-2019-0383.R1
Conclusion
Patients 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.

Background:

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

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

Hip Resurfacing at Surface Hippy 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.

Read or download the pdf here

…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…

Dr. Pritchett Discusses Hip Resurfacing and Follow Up of 270 Patients

Hip Resurfacing at Surface Hippy Posted on by

Published on Aug 7, 2018

James Pritchett MD discusses the preference his patients have for hip resurfacing compared to hip replacement. No metal on metal implants were included and the follow-up averaged 11 years and up to 26 years. A polyethylene acetabular component with a ceramic or ceramic coated femoral implant was used. 270 patients. This was a statistically valid independent, blinded, paired bilateral study. More than 85% of patients with a well functioning hip replacement preferred their hip resurfacing side because of better function, feel and performance. The risks and survivorship of hip resurfacing compared to hip replacement was also better in the hand of Dr. Pritchett with a long term failure rate of less than 3.5%. The patients average age was 48 and … Read the rest

June 1, 2018 – BARCELONA, Spain – Total surface replacement may still be a viable hip arthroplasty option in young, active patients based on how well it fared in a study when it was revised to total hip replacement vs. primary THR that was revised to THR, according to a presenter at the EFORT Annual Congress…

…“Our study shows, therefore, that there is less blood loss, there’s a shorter length of stay and better function in patients undergoing revision of resurfacing as opposed to revision of a standard stemmed prosthesis,” Kent said… Read the rest

Aspirin, Xarelto show no difference in preventing venous thromboembolism after TJA.

Among patients who received 5 days of rivaroxaban prophylaxis after total hip or total knee arthroplasty, extended prophylaxis with aspirin was not significantly different from rivaroxaban in the prevention of symptomatic venous thromboembolism.

After patients received once-daily oral Xarelto (rivaroxaban, Bayer Pharma) until postoperative day 5, Michael Dunbar, MD, FRCSC, PhD, and colleagues then randomly assigned 3,424 patients undergoing either THA or TKA to continue rivaroxaban or switch to aspirin for an additional 9 days after TKA or for 30 days after THA. The primary effectiveness outcome was symptomatic venous thromboembolism 90 days after randomization and the primary safety outcome was bleeding complications, including major or clinically relevant … Read the rest

Patients Living Alone can be Safely Discharged and Sent Home After Surgery

Hip Resurfacing at Surface Hippy Posted on by

Washington D.C. [USA], Jan. 20 : A study has recently revealed that patients who live alone can be safely discharged and sent home from a hospital to recover from hip or knee replacement surgery.

The results question the belief that patients who live alone should routinely be sent to an inpatient rehabilitation facility after total joint replacement surgery before going home.

Researchers said, “Patients living alone had a safe and manageable recovery when discharged directly home after total joint Arthroplasty.”

Andrew N. Fleischman and colleagues from The Rothman Institute, Thomas Jefferson University, Philadelphia, conducted the study.

The team examined 769 patients who were discharged and sent home after one-sided total hip or knee replacement. Of these, 138 patients were living alone for the first two … Read the rest

Updated Guidelines To Monitor Metal on Metal Devices by UK’s MHRA 2017

Hip Resurfacing at Surface Hippy Posted on by

Original MEDICAL DEVICE ALERT by UK MHRA 2017 Available Here

The Medicines and Healthcare products Regulatory Agency (MHRA) UK has called for longer-term monitoring of all patients fitted with metal-on-metal hip implants, as a precautionary measure, in an update to its original guidance issued in 2012.

“MHRA, in colsultation with its independent Metal-on-Metal Expert Advisory Group (MoM EAG), has continued to monitor the performance of MoM hip joint articulations for the occurrence of soft tissue reaction associated with these devices. However, some patients will develop progressive soft tissue reactions to the wear debris associated with MoM articulations.”

Advice varies according to device, age and sex of patients.  The BHR is device with a 10A ODEP rating.  Those patients are recommended to have follow-ups and blood … Read the rest

Women More Sensitized than Men to Metal in Hip Replacement Medical Study

Read Complete Study Here

Recent studies indicate that females demonstrate an increased risk of experiencing adverse local tissue reactions, aseptic loosening, and revision after primary metal-on-metal hip resurfacing arthroplasty compared with males; the underlying biological mechanisms responsible for sex discrepancies in implant failure remain unclear. In addition to anatomical and biomechanical sex differences, there may be inherent immunological disparities that predispose females to more aggressive adaptive immune reactivity to implant debris, i.e., metal sensitivity…

…The findings support the possibility that the higher rate of complications after TJA in women may have an “adaptive immunological basis.” But it is still unclear whether the sex-related difference in immune sensitization is related to intrinsic biologic factors, such as hormones, or to environmental factors, such as exposure to metals … Read the rest
