WelcomeSticky PostingsWelcome to Hip Resurfacing News Hip Resurfacing came of age in the United States when the FDA approved Birmingham Hip Resurfacing (BHR) in May 2006. Previous to the FDA Approval, hip resurfacings were done in Europe, Canada, Australia and other countries outside the United States. Orthopedic surgeons have been performing hip resurfacing surgeries since 1997 in most countries. Over 90,000 people world wide have received hip resurfacings. Since the FDA Approval of the BHR and Cormet in the US, there are a large number of new surgeons learning the techniques and many people wondering if the surgery is right for them. There are new surgeons training, new medical studies completed regularly and general articles published in newspapers, magazines and in the media daily. Keeping up with all of the information becomes a real task for most people. People are trying to find pertinent information without spending hours and hours searching online - that is the purpose of Hip Resurfacing News.

Diagnosed with osteoarthritis in
her late 20s, she tried a range of treatments from water aerobics to Vioxx. But
her condition only got worse. Finally, an orthopedic surgeon recommended total
hip replacement. She worried that she was too young for such surgery, but she
just couldn't stand the discomfort any longer. "The pain was gone immediately,"
says Seeley, now 49. Three months ago, she had her right hip done; she's already
back at work.

Transcript of Dr. Mont Live Chat July 16, 2008Tuesday, July 8. 2008High Impact Sports and Metal on Metal Bearing SurfaceThursday, April 3. 2008
March 2008
SAN FRANCISCO - A study indicates that having a metal-on-metal bearing surface and performing high-impact activities preoperatively may be positive predictors for participating in high-impact sports after total hip arthroplasty. To determine which patients would participate in high-impact sports activity following total hip arthroplasty (THA) and to examine the factors linked to participation in these sports, David R. Marker, BS, and colleagues submitted pre- and postoperative questionnaires to 303 THA patients who had a mean follow-up of 3 years. The investigators found that 30% of patients participated in at least one or more high-impact sport postoperatively for an average of 4.3 hours per week. A regression analysis revealed that a preoperative high activity level and metal-on-metal bearing surface were the only statistically significant factors to predict participation in high-impact sports postoperatively. Moreover, while a comparison of patients participating in high- and low-impact sports revealed similar preoperative Harris Hip Scores, the investigators discovered that the high-impact sport participating patients had higher postop Harris Hip Scores. "There are many patients participating in these high-impact sports, up to 30% in our cohort," Marker said during his presentation at the American Academy of Orthopaedic Surgeons 75th Annual Meeting, held here. "The preoperative participation, as well as the metal bearing surface, were found to be predictive of postoperative participation. We found [in] the short-term follow-up that the high-impact sports patients had similar and better outcomes." For more information: Marker DR, Seyler TM, Ulrich SD, et al.

Hip Resurfacing Advantage over THR StudyWednesday, September 26. 2007
Study: Surface replacement arthroplasty may offer advantages over THA
Canadian investigators said hip resurfacing resulted in greater patient activity after 2 years. By Robert Trace 1st on the web (September 19, 2007) September 2007 SEOUL — Total hip arthroplasty is an established procedure with well-documented complication rates and clinical results, but surface replacement arthroplasty may offer additional clinical benefits to many patients, according to a group of Canadian researchers. "We decided in 2003 to do a comparative study of hip resurfacing, or surface replacement arthroplasty (SRA), to the gold standard of total hip arthroplasty (THA), since we were not aware of any direct prospective studies out there comparing the two procedures," said Pascal-André Venditolli, MD, of the Maisonneuve-Rosemont Hospital in Quebec. He and his colleagues randomly assigned 210 hips to receive uncemented metal-on-metal THA (103 hips) or a hybrid metal-on-metal SRA (107 hips). All surgeries were performed by three orthopedic surgeons, who used a posterior approach. The researchers prospectively collected perioperative and postoperative data, and analyzed the clinical data for a minimum of 2 years. Postop complications included three isolated traumatic dislocations and one recurrent dislocation in the THA group, which required acetabular cup revision. Two SRAs required revision for late head collapse. No postop femoral neck fractures occurred in the SRA group, he said. There was one case of loosening at 6 months postop in the resurfacing group, which had shifted varus. There were also two cases of deep venous thrombosis in both patient groups, he said. Although the investigators did not report a significant difference in surgical time between the two procedures, patients' length of stay in the hospital was significantly shorter for the SRA group compared to the THA patients — 5 days vs. 6.1 days for the THA group (P=.001). "There was also a significant difference in return to work: 96% of the SRA patients returned to their previous work within 1 year vs. 83% in the THA group," Venditolli said. Although patients in both groups demonstrated a high satisfaction rate and achieved similar WOMAC and Merle d'Aubigné functional scores, "SRA patients had better UCLA activity scores (7.1 vs. 6.3; P=.037) and returned to heavier activities (P=.035)" after 2 years, he said. "This randomized study shows that SRA and THA present a similar complication rate, but distinctive complications," Venditolli said. "It also suggests that SRA results in better function and improved patient activity in comparison to THA. "However, the effect of long-term fixation related to increased activity levels is unknown. Long-term follow-up is necessary to determine the survivorship of SRA over THA," he said. For more information: Vendittoli P-A, Lavigne M, Lusignan D, Roy A-G.

Hip Resurfacing Compared to THR for Young PatientsWednesday, September 26. 2007
Comparative Arthroplasty Alternatives for the Young Arthritic
By Thomas P. Schmalzried, MD ORTHOPEDICS 2007; 30:756 September 2007 Thomas P. Schmalzried Hip resurfacing is embraced by patients. In principle, the attraction is similar to smaller incisions: patient satisfaction is related to the degree of invasion of their body. Hip resurfacing is driven by the Internet, with an Internet pro-resurfacing culture perceiving total hip replacement (THR) as an older technology and an older person’s operation. This perspective is fueled by the historical risk of dislocation, traditional activity restrictions, and concerns of component loosening with bone loss leading to morbid revision THR. There is a paucity of patient awareness regarding the outcomes of current-generation THR. In fact, there is a paucity of studies comparing current-generation THR and total resurfacing. Indications for Total Hip Resurfacing Total resurfacing and THR are not directly competing technologies. The indications for hip resurfacing are more limited. Not all patients who are candidates for THR are good candidates for resurfacing . Categorically, total hip resurfacing should be considered for those patients at increased risk for failure of THR. Historically, such patients are young and healthy, with men being at greater risk than women. Patients who have been told they are too young for THR have embraced resurfacing. The operative parameters for conversion of a failed resurfacing to THR are similar to those for a primary THR.(1) With current technology, the acetabular component size and position are essentially the same for total resurfacing and THR.2 The issues are on the femoral side and include: Bone Density. The risk of femoral neck fracture following resurfacing is related to bone density, with an increased risk in women and men >65 years.3,4 Head-to-Neck Ratio. Because resurfacing occurs around the femoral neck, it is technically helpful to have a head-to-neck ratio >1.2. Femoral Offset and Limb Length. With resurfacing, femoral offset and limb length cannot be changed to a practically significant degree; therefore, these parameters should be close to normal (>120° neck-shaft angle and limb-length difference within 1 cm).2 Focal Defects. Because focal defects undermine support for the component, large necrotic segments or cystic defects are undesirable.5 Hips that have all 4 of these criteria are arthritic hip grade (AHG) A, which is basically a normal hip with no cartilage. Grade B hips lack 1 factor, grade C hips lack 2 factors, and grade D hips lack 3 factors.6 Clinical Results In our series of more than 350 consecutive total hip resurfacings(7),
there have been no femoral neck fractures. After a 2-year minimum follow-up, AHG
was significantly associated with preoperative Harris Hip score (A>B>C),
occurrence of mild to moderate postoperative pain (A<B & C), and hip range of
motion. In other words, hips with a lesser degree of secondary arthritic changes
had a higher AHG and a better outcome. The mean UCLA activity score was 8.2, but
activity scores were higher for higher hip grades. These data support the
selection criteria and also support relatively early intervention. Correspondence should be addressed to: Thomas P. Schmalzried, MD, Joint
