Satisfactory long-term results seen with skin traction for reduction of hip dislocations

Researchers from Oslo University Hospital in Norway found a 74% survivorship, indicating no need for total hip arthroplasty, at 50-year follow-up for pediatric patients with late-detected hip dislocation who underwent skin traction to produce a gradual closed reduction.
“The clinical and radiographic outcomes after gradual closed reduction by skin traction were satisfactory in approximately two-thirds of eighty-three hips,” Terje Terjesen, MD, PhD, and
colleagues wrote in their study. “The most important independent risk factors for a poor long-term outcome were an age of 18 months or older at the time of reduction, residual subluxation, and osteonecrosis.”
Terjesen and colleagues retrospectively studied 71 patients (90 hips) who had a mean age of 1.7 years at the time of reduction, which occurred between 1958 and 1962. The patients had a mean follow-up of 50 years. The investigators discovered seven hips failed and needed open reduction. Thirty hips developed residual hip dysplasia and required late surgical procedures. A Harris Hip Score of at least 85 points following closed reduction was observed in 63% of the hips. No osteoarthritis was found in 67% of hips, according to the study abstract. Of the 27 hips that developed osteoarthritis, 19 underwent total hip replacement. Patients had this procedure at a mean age of 43.7 years.—by Christian Ingram
