The early results of metal-on-metal hip resurfacing - a prospective study at a minimum two-year follow-up.
Hip resurfacing has recently been offered as an attractive alternative to conventional total hip arthroplasty. This report evaluated the short-term functional outcome and longevity of a newer generation resurfacing device and includes the results of 228 consecutive hip resurfacing in 209 patients at a minimum of two-year follow-up. All resurfacing were performed by a single surgeon using a posterior approach. ⋯ The overall survival at 4.6 years was 96.9%. The survival of resurfacing in this study was comparable to that of other published studies of hip resurfacing. Surface hip arthroplasty appears to be an effective alternative to conventional total hip arthroplasty in patients suffering from osteoarthritis.

Comparative StudyResurfacing matched to standard total hip arthroplasty by preoperative activity levels - a comparison of postoperative outcomes.
Some studies have suggested that resurfacing patients are generally more active postoperatively than their conventional total hip arthroplasty (THA)counterparts, but controversy remains over whether this is a reflection of preferential use of resurfacing for younger and higher-activity patients. We hypothesized that, when controlling for preoperative activity levels, in addition to relevant clinical and demographic factors, resurfacing provides similar results to conventional hip arthroplasty. ⋯ The results of this study suggest that patients treated with hip resurfacing arthroplasty have a significantly higher postoperative activity level, as compared to those treated with conventional THA, when controlled for preoperative factors.

Safety reporting in randomized clinical trials - a need for improvement.
The reporting of adverse events (AEs) in randomized clinical trials (RCTs) is often lacking in the publication of trials. Part of the problem is the way safety data are reported in RCTs. Reporting of "time to event," use of standardized incidence ratios for comparison to normal population or disease controls, use of "patient years" when reporting AE, and adequate sample size and power calculations are some of the problems that need to be addressed and improved in RCTs.

Long-term functional outcome and donor-site morbidity associated with autogenous iliac crest bone grafts utilizing a modified anterior approach.
Prior studies and techniques for harvesting iliac crest bone have shown significant postoperative pain, disability, and poor cosmesis. This retrospective study was conducted to examine bone graft donor-site morbidity by evaluating functional outcomes in patients who have undergone a modified anterior harvesting approach. The medical charts and hospital records of 43 patients were retrospectively reviewed over a 6-year period. ⋯ SMFA scores demonstrated a mean dysfunction score of 48.5 (range, 41.8 to 71.1) and a bother index of mean 47.9 (range, 42.6 to 73.9). Utilizing the anterior approach in iliac crest bone harvesting provides an abundant supply of both cortical and cancellous bone, an aesthetically favorable scar, and decreased postoperative donor-site pain. There were very few complications seen in our cohort as compared to previous studies with very good long-term functional outcomes.
