In this article author discuss medium term results of first or next secondary replacement of acetabular part of hip endoprosthesis--after filling up cavernous or segmental bone defects. There were analysed 104 operated hips 70 (67.3%) female and 34 (32.7%) male. Bilateral hip arthroplasty (in two sessions) was performed in 14 women and 5 men. The average age was 69.8 years. The mean time between the primary arthroplasty and the revision was 12.1 years. The follow up was 2-15 years, mean 5.4 years. Cemented acetabulum was used in 71 revisions (68.3%), self-threaded in 19 (18.3%) and pressed in 14 (13.5%). Destabilization and migration of acetabular part of prosthesis appeared in 14 events (13.5%). Radiolucency local zones on X-ray referred to possible pseudomembrane round the acetabular part without clinical manifestations were shown in 19 cases (18.3%). The study demonstrated that migration of acetabular part of hip prosthesis due to secondary stabilisation deficiency took place in hips were proper primary stabilisation was not achieved because of extensive bone defects.

Background: Different methods can help to optimise sagittal cup orientation in total hip arthroplasty (THA) based on individual spinopelvic characteristics. This study aimed to: (1) assess how often combined sagittal index (CSI) and hip-spine-classification targets were achieved post THA; (2) compare anteversion/inclination between cups in-/outside optimal CSI zone; and (3) determine association with outcome.
Methods: This is a multicentre, prospective, case-cohort study of 435 primary THA for osteoarthritis (53% females; age: 65 ± 12 years; follow-up: 2.

Background: The risk of early revision of total hip arthroplasty (THA) for polyethylene wear is now low, but there remains a need to perform wear measurements in patients for clinical surveillance. The gold standard of wear measurements has been radiostereometric analysis (RSA), which has limited availability. The use of computed tomography (CT) to perform THA wear measurement was described a decade ago and found to have acceptable accuracy and precision, but high radiation dose was a concern.

: Developmental dysplasia of the hip (DDH), defined by the malalignment of the femoral head and acetabulum, is a major precursor to coxarthrosis, posing substantial challenges during total hip arthroplasty (THA). Patients with coxarthrosis secondary to DDH often exhibit acetabular bone insufficiency, which makes challenging surgical reconstruction difficult. This study aimed to compare the radiologic and functional outcomes of robotically assisted and conventional manual THA techniques in patients with coxarthrosis secondary to Crowe type III-IV DDH.

Background/objectives: Bone marrow adipose tissue (BMAT) has been described as an important biomechanic and lipotoxic factor with negative impacts on skeletal and hematopoietic system regeneration. BMAT undergoes metabolic and cellular adaptations with age and disease, being a source of potential biomarkers. However, there is no evidence on the lipid profile and cellularity at different skeletal locations in osteoarthritis patients undergoing primary hip arthroplasty.
