This study was designed to evaluate the feasibility and effectiveness of the use of anhydrous alcohol as an adjuvant treatment for giant cell tumours (GCTs) of long bone. Between October 1989 and January 2004, 42 GCT patients were treated and followed up for an average of 4.1 years (range 1–13 years). Mean patient age was 34 years (range 17–67 years). After curettage and additional burring, anhydrous alcohol was used as an adjuvant therapy in all patients before the bone defect was filled with bone graft or cement. Four patients (9.5%) experienced local recurrence. There were no alcohol-related complications. Recurrence-free probability was 87.6% at final follow-up (13 years) after index surgery by Kaplan–Meyer analysis. Our data suggest that anhydrous alcohol can be used as an effective safe adjuvant for the treatment of GCT of long bone.

E purpose of this study was to determine the prevalence of radiographic findings in the proximal femur that are consistent with FAI in asymptomatic Korean volunteers. Methods Two hundred asymptomatic volunteers with no prior hip surgery or childhood hip problems underwent three-view plain radiographs (pelvis AP view, Sugioka view, and 45° Dunn view) of both hips. There were 146 hips from male volunteers and 254 hips from female volunteers in the study. The mean age of all participants was 34.7 years (range, 21-49 years). Cam-type morphologic features were defined as the presence of the following on one or more of the three views: pistol-grip morphologic features, an osseous bump at the femoral head-neck junction, flattening of the femoral head-neck offset, or alpha angle greater than 55°. Pincer-type morphologic features were determined by radiographic signs, including crossover sign, deficient posterior wall sign, or lateral center-edge angle greater than 40°. Results The prevalence of cam-type morphologic features seen on at least one radiograph was 38% (male, 57%; female, 26%). The prevalence of cam-type features (at least one positive cam-type feature) was 2.0% (male, 6%; female, 0%) on the pelvic AP view, 24% (male, 36%; female, 17%) on the Sugioka view, and 30% (male, 47%; female, 20%) on the 45° Dunn view. The prevalence of pincer-type morphologic features (at least one positive pincer-type feature) was 23% (male, 27%; female, 21%) on the pelvic AP view. Conclusion The prevalence of FAI-related morphologic features in asymptomatic Asian populations was comparable to the prevalence in Western populations. Considering the high prevalence of radiographic hip findings reminiscent of FAI in asymptomatic Asian populations, it will be important to determine whether FAI-related morphologic features are a cause of hip pain when considering surgery in Asian patients....
