ABSTRACT
PURPOSE: This study analyzed the factors related to a variable inclination angle in patients who have undergone total hip arthroplasty by taking pelvis AP X-rays in the lateral decubitus position with a 45degrees targeted goniometer. MATERIALS AND METHODS: We recruited 100 adults (50 men and 50 women) who were without a history of hip joint disease. The mean age was 30.1 years for the men and 33.7 years for the women. The circumferences of the shoulder and pelvis, the shoulder to pelvis ratio, and the body mass index were checked. We examined the radiographs with using a goniometer, which was targeted to 45degrees for allowing a rod to be across the center of the acetabulum. The cross angle between the rod and the interteardrop line was checked. RESULTS: On the comparison of the gender groups, the shoulder to pelvis ratio was on average 1.18 in men and it was 1.08 in women. The mean cross angle was 45.3degrees in men and 48.1degrees in women. As the ratio was increased, the cross angle decreased. CONCLUSION: For men, there was little pelvic tilt in the lateral decubitus position. But for women, if inserting the acetabular cup with the acetabular orientation at 45degrees is done without considering the pelvic tilt inclination at the lateral decubitus position, then the inclination angle could be lower than expected.

PURPOSE: We evaluated the clinical results of the intraarticular calcaneal fractures treated using Ollier approach by inexperienced orthopaedic surgeon. MATERIALS AND METHODS: Between August 2003 and May 2007, Of the total 46 cases, 12 cases (9 patients) of displaced intraarticular calcaneal fracture who underwent open reduction and internal fixation using Ollier approach were evaluated. The means of age was 50.5 years. According to the Sanders classification, there was no type I case and 8 cases of type II, 1 case of type III, and 3 cases of type IV. We evaluated the treatment result by assessing radiologic parameters (Bohler angle, Gissane angle, and calcaneal height/width) and clinical outcomes (VAS and AOFAS score). RESULTS: The means of follow-up period was 25.3 months. The means of Bohler angle was improved from 2.4degrees to 26.1degrees. Radiologic and clinical union was achieved in all cases without additional procedures. Excellent result were noted in 2 cases, good in 5 cases, fair in 4 cases, and poor in 1 case. We experienced 2 cases of minor complications; 1 case of mild wound infection and 1 case of hypoesthesia on foot dorsum. Radiologic findings of subtalar arthritis were present in 2 cases. CONCLUSION: Ollier approach seems to be helpful to inexperienced orthopaedic surgeons for the treatment of intraarticular calcaneal fractures in that it enables them to achieve considerable clinical outcomes without serious complications.
