“…The initial anterior change in PIA may compensate for wound pain because VAS pain had significantly decreased at 3 weeks after THA, suggesting that hip pain following THA was associated with PIA. The posterior change in pelvic tilt after THA was in agreement with other reports 9,10) .…”

Abstract.[Purpose] We investigated whether pelvic inclination angle (PIA) influences hip abductor strength and gait ability after total hip arthoplasty (THA). Additionally, we assessed whether preoperative PIA is useful as a predictor of hip abductor strength and ambulation ability after THA.[Subjects] Thirty-six women patients with unilateral THA (age: 67.9 ± 10.0; body weight: 56.8 ± 9.1 kg; height: 150.2±8.3 cm; BMI: 25.1±3.6 kg/m 2 )participated in this study.[Methods] We measured pre-and postoperative PIA, hip abductor strength, hip pain (visual analog scale: VAS), and subjects performed the timed up and go (TUG) test, and the 10-m gait speed test.[Results] PIA showed onetime decrease in pelvic tilt at 1 week postoperatively, and thereafter generally exhibited a posterior change after THA. The patients with postoperative posterior PIA showed late recovery of abductor muscle strength and inferior TUG test results compared to patients with anterior or neutral PIA. The hip abductor strength and TUG test results of patients with preoperative posterior PIA were significantly lower than those of patients with preoperative anterior or neutral PIA.[Conclusions] PIA affected hip abductor strength and TUG test resulting, which were associated with a decrease in hip pain, and preoperative PIA may be useful for predict short-term hip abductor strength and ambulation ability after THA.

In most patients with hip disorders, the anterior pelvic plane (APP) sagittal tilt does not change from supine to standing position. However, in some patients, APP sagittal tilt changes more than 10˚posteriorly from supine to standing position. The purpose of this study was to both examine APP sagittal tilt and investigate the hip flexion and extension range of motion (ROM) required during daily activities in these atypical patients. Patient-specific 4-dimensional (4D) motion analysis was performed for 50 hips from 44 patients who had undergone total hip arthroplasty. All patients divided into two categories, such as atypical patients for whom the pelvis tilted more than 10˚posteriorly from supine to standing position preoperatively (19 hips from 18 patients) and the remaining typical patients (31 hips from 26 patients). The required hip flexion and extension angles did not differ significantly between atypical patients and typical patients. In conclusion, the hip flexion ROM during deep bending activities and hip extension ROM during extension activities required in those atypical patients with pelvic tilt more than 10˚backward from supine to standing position did not shift in the direction of extension.

The pose of the prosthetic components after total hip arthroplasty (THA) is commonly evaluated on conventional radiographs. Any change of the pelvic position after the operation in supine and between supine and standing position with time will influence validity of the measurements. We evaluated the changed pelvic tilt angle (PTA) in supine and standing position up to 7 years after operation. The aims of our study were (a) to evaluate if the PTA change over time after THA, (b) to assess any difference in PTA between supine and standing positions, and (c) to investigate whether factors such as gender, the condition of the opposite hip or low-back pain have any influence on PTA after THA. Repeated radiostereophotogrammetric radiographs of 106 patients were studied. Patients had been examined in the supine position postoperatively, and in both supine and standing positions at 6 months and 7-year follow-up. Measurements of supine patients showed an increasing mean posterior pelvic tilt over time. From supine to standing, the pelvis tilted in the opposite direction. At 6 months, the mean anterior tilt was 3.6°± 3.8°(confidence interval [CI]: 2.8°to 4.3°) which increased to 6.4°± 3.9°(CI: 5.7°to 7.2°) at 7 years. The mean changes in pelvic rotations around the longitudinal and sagittal axis were less than 1 degree, in both positions. In individual patients, this change reached about 11.0 degrees in supine and 18.0 degrees when standing.
