Elmarghany M, El-Ghaffar TMA, Elgeushy A, et al. - This study was attempted to assess the effectiveness of the osteochondroplasty with relative neck lengthening in adults with healed Perthes clinically (through assessment of impingement-free hip ROM, functional scores) and radiographically. Researchers conducted a prospective case series study including 30 hips of 30 patients who had undergone osteochondroplasty and RNL due to symptomatic healed Legg-Calvé-Perthes disease. This research enrolled 16 males (53.3%) and 14 females (46.7%) [the age of patients ranged from 19 to 40 years with mean age 26.4 years at the date of surgery (SD 6.4)]. This study's findings demonstrate that head and neck osteochondroplasty conducted through the surgical dislocation method, combined with RFNL, relieved pain, and restored function in most of the individuals with reasonable complications.
