“…However, a recent epidemiological study of hip OA in Japan demonstrated that the incidence of acetabular dysplasia was lower in elderly patients [21]. Lane et al [30] also reported that the association between acetabular dysplasia and OA in white women aged ≥65 years was not determined.…”

“…In Japan, developmental acetabular dysplasia of the hip is reportedly among the most common causes of hip OA [19, 20]. Meanwhile, the incidence of acetabular dysplasia is lower in elderly patients [21]. The incidence and prevalence of OA after 50 years of age are higher in women than in men, suggesting that estrogen participates in the development of OA [22].…”

Osteoarthritis of the hip joint in elderly patients is most commonly atrophic, with low parameters of acetabular dysplasia and possible involvement of osteoporosis

SummaryAs elderly patients with hip osteoarthritis aged, acetabular dysplasia parameters decreased (Sharp’s angle, acetabular roof obliquity angle, and acetabular head index) and the incidence of the atrophic type increased. Vertebral body fracture was more frequent in the atrophic type, suggesting the involvement of osteoporosis at the onset of hip osteoarthritis.IntroductionOsteoarthritis (OA) is associated with increased bone formation at a local site. However, excessive bone resorption has also been found to occur in the early stages of OA. Osteoporosis may be involved in the onset of OA in elderly patients. We conducted a cross-sectional radiographic study of patients with hip OA and examined the association between age and factors of acetabular dysplasia (Sharp’s angle, acetabular roof obliquity angle, and acetabular head index) as well as the osteoblastic response to determine the potential involvement of osteoporosis.MethodsThis study included 366 patients (58 men, 308 women) who had undergone total hip arthroplasty for the diagnosis of hip OA. We measured the parameters of acetabular dysplasia using preoperative frontal X-ray images and evaluated each patient according to Bombelli classification of OA (hypertrophic, normotrophic, or atrophic type).ResultsAs the patients aged, the parameters of acetabular dysplasia decreased. The incidence of the atrophic type of OA was significantly higher in older patients. Vertebral body fractures were more frequent in the atrophic type than in the other types. Additionally, the index of acetabular dysplasia was lower in the atrophic type. By contrast, the hypertrophic type was present in relatively younger patients and was associated with an increased index of acetabular dysplasia.ConclusionIn elderly patients with hip OA, the parameters of acetabular dysplasia decreased and the incidence of the atrophic type increased as the patients aged. The frequency of vertebral body fracture was high in patients with the atrophic type, suggesting the involvement of osteoporosis in the onset of hip OA.

Purpose The aims of this retrospective study were to firstly introduce three practical bulk bone graft techniques based on acetabular morphology for dysplasia and secondly evaluate the long-term durability of acetabular reconstruction using those techniques combined with cemented total hip arthroplasty (THA). Methods The study comprised 101 consecutive THAs with a minimum follow-up of ten years; these procedures were categorised as being L shape (n=58), Wall (n=33) and D shape (n=10) types. Results At the last follow-up, all bone grafts acquired trabecular reorientation, and no evidence of revision for aseptic or radiological loosening was noted. Conclusions These bone graft techniques will be effective for improving the management of dysplasia in cemented THA by providing both acetabular reconstruction and cement containment.

“…[1][2][3] In DDH, lateralization of the center of the hip joint occurs due to insufficient coverage of the femoral head by the acetabulum, a reduction of the weight-bearing area of the acetabulum, and an increase in the hip joint contact pressure, which induces degenerative changes in cartilage in the early phase. [4][5][6][7][8] This harmful mechanical condition results in dysfunction, such as coxalgia and claudication, which then progresses to secondary osteoarthritis of the hip.…”

Purpose: The objective of the study was to prospectively investigate the characteristics of gait among patients before and soon after curved periacetabular osteotomy (CPO) in comparison with healthy subjects. Subjects and methods: The subjects were six patients who underwent CPO and six healthy adults. Gait analysis was performed before surgery and at an average of 7.3 months after surgery using a three-dimensional motion analysis system. Temporospatial factors (gait velocity and stride length) and kinematic factors (range of motion of the hip joint in the sagittal plane, and ranges of tilting movement of the trunk and of the pelvic region in the coronal plane) were evaluated. Results: Gait velocity increased after surgery, but it was significantly lower than that of the healthy group (P,0.05). Stride length significantly increased after surgery compared to before surgery (P,0.05), though the significant difference seen before surgery disappeared. The full range of motion of the hip joint in the sagittal plane during walking increased after surgery, though the significant difference evident between the two groups before surgery also disappeared. The range of tilting movement of the trunk during walking increased after surgery, with a significant difference emerging when compared to the healthy group, which was not observed before surgery (P,0.05). Conclusion:The characteristics of gait were investigated in patients treated with CPO before and after surgery, and compared with those in healthy subjects. Gait improved, except for sway of the trunk while walking, despite the analysis being performed soon after surgery. Keywords: curved periacetabular osteotomy, gait analysis, range of motion of the hip joint, range of tilting movement of the trunk
