These soft tissues are critical for the normal biomechanical functioning of the joint. After total hip arthroplasty (THA), the range of motion of the hip is reduced, with limited abduction moment and angle compared to nonoperated hips. Similar to the previously discussed joints, the major role ...
7-48). The angle created between lines drawn along the straight part of the iliac bone and the acetabular roof form what Graf calls the alpha angle (see Fig. 7-48). Normally, the alpha angle is greater than 60 degrees (55 degrees in newborns). In DDH the acetabulum is shallow, ...
Average follow-up was 2.6 years (range 23-59 months). The cohort experienced clinical improvement (p<0.001) in all patient-reported outcome measures. The mean improvement was 21.4 points for HHS, 17.4 for HOS ADL, 29.5 for HOS Sport, and 34.3 for QOL. There was no significant difference ...
irrigated.A femoral osteoplasty was then performed to remove the cam deformity. A small hole was subsequently drilled into the femoral head, confirming bleeding vascularized bone. The hip was reduced and was found to be stable through full range of motion. Intraoperative fluoroscopy imaging was ...

In our opinion, taking CE angle as an example, there might be a safe range, below/above a specific mini- mum/maximun threshold would increase the risk of hip OA. But the precise range needs to be further explored. Further comparison of the contact mechanics between normal and OA samples ...
Compared to the sole PAO group, both postoperative alpha angle and range of joint motion improved in the PAO combined with osteochondroplasty group. However, no difference in HHS score was found. Conclusions Good survivorship and improved joint function were identified in middle-aged Chinese ...
The patients with OA had a greater percentage with abnormal alpha angles than did the normal subjects: 82% versus 30%, respectively. The mean alpha angle in the group with OA was larger than in the control subjects: 66.4º (range, 28°–108°) versus 48.1º (range, 34°–68°)...
