“…In a simulation study, Tabata et al reported that in cases of Hetstroni's classification type III, 20 in which the AIIS overhangs distal to the acetabular margin, the range of flexion and internal rotation after THA decreases 9 . Shoji et al reported that the AIIS protruded more laterality from the head center in males with DDH than that in females with DDH by measuring the distance of the AIIS from the head center 8 .…”

“…4,5 Bone impingement at the AIIS after THA can be a cause of dislocation. [8][9][10] We proposed that pelvic morphology, including AIIS, with DDH could affect the ROM after THA. Compared with the position of the AIIS in the pOA, the position of the AIIS in the DDH protrudes more medially and cranially from the TD, which causes an increase in ROM.…”

“…DDH has been reported to display unusual pelvic morphology as well as different overall acetabular coverage 6,7 . Previous studies have shown that peri‐acetabular morphological abnormalities affect postoperative dislocation due to bony impingement following THA 8,9 . We proposed that the different peri‐acetabular morphologies in pOA and DDH may be responsible for the different dislocation rates observed after THA.…”

“…[8][9][10] A previous simulation study revealed that an AIIS overhanging caudal to the acetabular rim significantly decreases the range of motion (ROM) for flexion and internal rotation. 9 Another simulation study reported that the distance between the center of the head and the AIIS after THA will influence the range of flexion and internal rotation. 8 However, it is not fully understood how the position of the AIIS in DDH differs from that in the normal hip.…”

Bony impingement, especially in the anterior inferior iliac spine (AIIS) after total hip arthroplasty (THA), may cause dislocation. However, the influence of AIIS characteristics on bony impingement after THA is not fully understood. Thus, we aimed to determine the morphological characteristics of AIIS with developmental dysplasia of the hip (DDH) and primary osteoarthritis (pOA) and to evaluate its effect on range of motion (ROM) after THA. Hips from 130 patients who underwent THA, including pOA were analyzed. In total, we had 27 male and 27 female participants with pOA, and 38 male and 38 female participants with DDH. The horizontal distances of AIIS from teardrop (TD) were compared. In the computed tomography simulation, flexion ROM was measured, and its relationship to the distance between TD and AIIS was investigated. DDH had a more medial (male: DDH, 36.9 ± 5.8; pOA, 45.5 ± 6.1; p < 0.001) (female: DDH, 31.5 ± 10.0; pOA, 36.2 ± 4.7; p < 0.001) position of AIIS than pOA. In the male with pOA group, flexion ROM was significantly smaller than that in the other groups, and there was a correlation between flexion ROM and horizontal distances (r = −0.543; 95% confidence interval = −0.765 to −0.206; p = 0.003). AIIS position is a factor that limits ROM during flexion after THA, particularly in males. Further studies are required to develop surgical strategies for cases of impingement at the AIIS site after THA. Level of evidence: Ш, retrospective comparative study.
