HILTON HEAD ISLAND, S.C. -- Osteomyelites following bone-anchor procedures is rare but can be easily missed, so physicians should be on the lookout for it, according to one expert.
"The risk is small, but there's serious morbidity with major reoperations, removal of infected bone, and a protracted healing time," said Dr. Roger Goldberg, a urogynecologist at the Evanston (Ill.) Continence Center.
The incidence of osteomyelitis following bone-anchored transvaginal bladder neck suspensions is 1.1%, according to the results of a study he presented at the annual meeting of the American Urogynecologic Society. This study is the first to peg the incidence of osteomyelitis in this population, according to Dr. Goldberg.
Since bone anchors were first introduced in 1992, the risks of osteomyelitis have been recognized but not quantified, he told this newspaper. "Physicians have wondered how much they need to worry about osteomyelitis. They know it's a serious complication, but on the other hand, it should be balanced against the benefits of bone anchors," he said.
In Dr. Goldberg's opinion, the attractions of bone anchors are the speed and ease with which they can be placed, the minimal dissection involved, and anchor stability.
A total of 268 patients who underwent the procedure at both his institution and the Cleveland Clinic Foundation were followed for a mean of 31.9 months.
There were three cases of pubic osteomyelitis, each requiring exploratory laparotomy, anchor removal, bony debridement, and prolonged parenteral antibiotics.
