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.
Methods: We surveyed 112 patients by postal questionnaire to determine their sporting activities at a mean of 23.5 (range, 9? 40) months after hip resurfacing surgery. Data were also analyzed separately for older and younger patients and women and men, respectively.
Hips previously treated with metal-on-metal resurfacing arthroplasty that require conversion to total hip arthroplasty can achieve short-term clinical and radiographic results similar to primary total hip replacement, according to a study by California researchers.
The purpose of this study was to compare clinical outcomes between ceramic-on-ceramic total hip replacement and metal-on-metal hip resurfacing arthroplasty in comparable groups of young active patients at a 3- to 6-year follow-up. The first 250 patients (mean age, 49.54 years) of a series of 930 resurfacing arthroplasties were compared clinically and functionally with a series of 190 patients (mean age, 46.76 years) with ceramic-on-ceramic uncemented total hip prostheses. The total Harris hip score was 97.9 in the resurfacing group vs 92.1 in the ceramic group. In the resurfacing group, 60.71% had a strenuous activity level vs 30.43% in the ceramic group.
The doubles champion Bob Bryan has urged Andy Murray to press ahead with the Birmingham hip operation, which he says will transform Murrays quality of life, and could even help him rejoin the professional tennis tour.
Smith & Nephew (LSE: SN, NYSE: SNN), the global medical technology business, announces the launch of their new REDAPT Revision Femoral System. Designed to bring the concept of personalized patient treatments to the revision hip market, the new system's versatility allows surgeons to effectively recreate a patient's unique functionality while quickly and easily addressing issues such as poor bone quality and proximal/distal mismatch.
A Florida law firm suing Stryker Orthopaedics over its Rejuvenate and ABG II hip implant systems says it has added seven more plaintiffs in the case. The plaintiffs are from Florida, Minnesota and Arizona.
If you have a patient with the presence of local symptoms such as pain or decrease in joint function that appear more than three months after metal-on-metal (MoM) hip implant surgery, you should conduct a thorough evaluation.
This is a 1.2- to 5.3-year survival and clinicoradiologic study of patients with the Birmingham Mid-Head Resection (BMHR) device (Smith & Nephew Orthopaedics, Warwick, United Kingdom). Sixty consecutive hips implanted with this device between 2003 and 2007 were reviewed with hip outcome questionnaires, clinical examination, and radiographs at a minimum follow-up of 1 year.
Stryker Face Mounting Lawsuits over Recalled Hips (Total Hip Replacements)
Heterotopic ossification is defined as bone formation in nonosseous tissues. Heterotopic ossification usually occurs in trauma such as fractures and surgical procedures. Heterotopic ossification of the hip, for example, is the most common complication of total hip arthroplasty (THA). It can occur in as many as 53% of THA patients, and it causes postoperative disability from pain and limited range of motion (ROM) 7% of the time.1 Heterotopic ossification also is seen in neurologic disorders such as spinal cord and brain injury.
This week, the Hospital for Special Surgery (HSS) in New York City will be holding a medical education course titled Total Hip: Replacement and Resurfacing on May 7 and 8 for leading hip surgery specialists from across the U.S. Chairing the course will be Edwin Su, MD, of the Hospital for Special Surgery, and the teaching faculty will include pioneering British surgeon Derek McMinn, MD, inventor of the BHR hip.
