ALTR uncommon after MOM hip resurfacing
According to a study in the Journal of Bone & Joint Surgery—American (May 4 supplement), adverse local tissue reactions (ALTRs) are uncommon after metal-on-metal (MOM) hip resurfacing. A survey of nine centers covering 3,432 MOM hip resurfacing arthroplasties found four ALTRs at mean 3.4-year follow-up (range 2 to 9 years), for a prevalence of 0.10 percent. The reactions remain a concern and MOM hip resurfacing patients should be monitored.

Diabetes patients and fracture risk
A study in the Journal of the American Medical Association (June 1) on the relationship between femoral neck bone mineral density (BMD) T score, World Health Organization Fracture Risk Algorithm (FRAX) score, and fracture risk in diabetes mellitus (DM) patients, based on data from 9,449 women and 7,436 men who participated in three prospective observational studies with adjudicated fracture outcomes, found that, of 770 women with DM, 84 experienced a hip fracture and 262 had a non-spine fracture during a mean follow-up of 12.6 years. Of 1,199 men with DM, 32 experienced a hip fracture and 133 had a non-spine fracture during a mean follow-up of 7.5 years. FRAX score was associated with fracture risk in participants with DM.
