New Guideline on Rotator Cuff Problems

Ken Yamaguchi, MD

Rotator cuff disease ranks among the most prevalent of musculo-skeletal disorders. Previous studies in both cadavers and patient populations have found the prevalence of rotator cuff tears may exceed 50 percent in individuals older than age 65. Given that this age group is the fastest growing segment of the U.S. population, rotator cuff disease is poised to become an even more significant problem in the future.

Researchers investigate treatment of giant-cell tumor with denosumab Giant-cell tumor (GCT) is a rare primary bone tumor that is osteolytic and has low metastatic potential. The rare metastases have a propensity for the lung. Surgery—usually curettage combined with cementation or allograft supplementation—is considered the primary therapy for GCT of bone. Despite this treatment, local recurrence can occur in 10 percent to 40 percent of patients.

Grant recipients use OREF funding to study wrist motion Nearly everyone, it seems, has what it takes to play a decent game of darts. Studies have shown that the movement of the wrist needed to throw a dart, generating a certain degree of force and reaching a desired target, is employed in such activities as combing hair, tying a shoe, and pouring from a pitcher. Although this motion may be common, it’s not well understood.

U.S. joint registry is poised to begin accepting data The American Joint Replacement Registry (AJRR) recently kicked off its pilot data collection project after receiving a “huge response” from hospitals and orthopaedists eager to take part, said David G.

International joint registries—from Australia to the United States Surgeons can draw their own conclusions about what joint registry data reveal, according to Steven Graves, MD, because registries neither interpret data nor make recommendations. Outcomes data obtained through registries, however, can help weed out lesser-performing devices and concepts. An orthopaedic surgeon from Adelaide, Australia, Dr. Graves spoke at the Combined Orthopaedic Associations Meeting in Glasgow, Scotland.
