“…Medializing the acetabular cup on the other hand will allow for a larger femoral offset, less joint loading, and therefore reduced wear 3049. This strategy can be useful in case of gluteal muscle insufficiency as well as to allow for a horizontal cup placement while maintaining sufficient bone coverage 4550. Moving the cup superiorly has been shown to increase joint loading by 0.1% for every millimeter of superior displacement of the hip center of rotation, which is however seven times lower than the 0.7% increase/mm when lateralizing the center of rotation of the hip joint 51…”

Biomechanics of the hip joint describes how the complex combination of osseous, ligamentous, and muscular structures transfers the weight of the body from the axial skeleton into the appendicular skeleton of the lower limbs. Throughout history, several biomechanical studies based on theoretical mathematics, in vitro, in vivo as well as in silico models have been successfully performed. The insights gained from these studies have improved our understanding of the development of mechanical hip pathologies such as osteoarthritis, hip fractures, and developmental dysplasia of the hip. The main treatment of end-stage degeneration of the hip is total hip arthroplasty (THA). The increasing number of patients undergoing this surgical procedure, as well as their demand for more than just pain relief and leading an active lifestyle, has challenged surgeons and implant manufacturers to deliver higher function as well as longevity with the prosthesis. The science of biomechanics has played and will continue to play a crucial and integral role in achieving these goals. The aim of this article, therefore, is to present to the readers the key concepts in biomechanics of the hip and their application to THA.

“…Two main reasons for the worse outcome were as follows: (1) insufficient coverage of metal shell due to defective acetabulum and (2) difficult cup positioning due to posttraumatic deformity of the acetabulum. 5,6,8 However, we used medialization technique to obtain sufficient acetabular coverage in patients with deficient acetabulum, 13,14 and we performed preoperative CT scan for accurate positioning of acetabular cup. 12 In our study, the results of THA due to posttraumatic arthritis were comparable with those due to osteonecrosis.…”

“…On the preoperative CT scan, we measured abduction and anteversion of the acetabulum to guide the cup positioning during the operation according to the method of Ha et al 12 If the depth of the osseous cavity was not sufficient to cover the acetabular component with host bone after acetabular reaming, the medial acetabular wall was more reamed to the level of medial cortex to deepen the cavity using the Dorr's technique, and the medial placement technique was used. 13,14 The acetabular and femoral components were inserted in a press-fit manner.…”

We aimed to evaluate (1) the intraoperative parameters, (2) cup position, (3) complications, (4) long-term results, and (5) the survivorship of cementless total hip arthroplastys (THAs) with use of ceramic bearings in patients with a history of acetabular fracture. Methods: We compared 57 THAs in patients, who were treated due to previous acetabular fracture (posttraumatic group), with 57 propensity score-matched THAs in patients, who were operated due to femoral head osteonecrosis (osteonecrotic group), at a minimum of 5-year follow-up. Results: The operation time was longer (p ¼ 0.008), and the volume of transfusion was larger (p ¼ 0.0.23) in the posttraumatic group. The cup abduction (39.4 + 6.0 vs. 39.7 +4.8) and anteversion (24.7 + 8.0 vs. 26.7 +7.7) were similar between the two groups. There was one dislocation in the posttraumatic group. There was no ceramic fracture in either group. One posttraumatic patient underwent excision of exuberant heterotrophic ossification at 3 years after the arthroplasty. The mean University of California, Los Angeles activity improved from 3.6 to 4.9 points in the posttraumatic group and 3.5 to 5.2 points in the osteonecrotic group. All acetabular cups and femoral stems had bone-ingrown stability. When reoperation for any reason was used as the end point, the 10-year survival rate was 98.3% (95% CI: 95.0-100) in the posttraumatic group and 100% in the osteonecrotic group. Conclusion: In our study, posttraumatic patients had longer operation time and larger volume of transfusion than osteonecrotic patients. However, medium-term results and survivorship were similar with those of osteonecrotic patients.

“…Current techniques for acetabular reconstruction are as follows: standard or custom-made metal augments, roof reconstruction with vascularized fibula or pedicled iliac graft, autologous or homologous bone, reinforcement rings, cranial positioning of the acetabulum, medial protrusion techniques (cotyloplasty) [2]. It has been reported that an 80% intact bone coverage is required for a stable acetabular reconstruction [18,19]. However, 30-40% uncovarage was reported acceptable in other studies [2,5].…”

Medial placement of the acetabular component in an alumina-on-alumina total hip arthroplasty: a comparative study with propensity score matching

Abstract: Thin acetabular medial wall and a small inclination angle of the cup were the correlating factors of medial placement of the cup in patients who underwent an alumina-on-alumina THA. Medial placement did not lead to differences in the clinical or radiological outcomes.
