Summary: This study compared the biomechanical effects of bionic trabecular metal and titanium jumbo cups for acetabular bone defect revision. Finite element analysis showed that bionic tantalum jumbo cups had superior stress distribution and higher relative micromotion compared to titanium jumbo cups. Therefore, we recommend the use of trabecular metal cups for acetabular reconstruction.

Summary: This study compared the cup survival and the incidence of adverse events associated with the use of trabecular metal (TM) and non-TM cups for acetabular revision surgery. The results showed no significant difference in cup survival between the two types of cups. Overall, TM cups had fewer adverse events, but the difference was not significant. The incidence of aseptic loosening and infection was significantly lower for TM cups, while the incidence of dislocation was significantly higher.

Summary: This study aimed to evaluate the changes in cup coverage and hip center of rotation in acetabular defects treated with acetabular revision using jumbo cups. The results showed that using jumbo cups for acetabular revision led to decreased cup coverage and an increase in hip center of rotation. The elevation of the hip center of rotation was significantly higher in patients with severe acetabular defects compared to other patients.

Summary: This study retrospectively analyzed 85 patients who underwent acetabular revision with a TT revision cup system, with a mean follow-up of 6.12 years. Results showed significant improvement in average HHS scores postoperatively, successful restoration of the hip rotation center, and good 5-year and 10-year survival rates of 100% and 88%, respectively.

Summary: This study retrospectively reviewed cases where TM cups were used for revision surgery after failed cage reconstruction with bone allografts. The results showed that the bone stock of the acetabulum significantly improved between index revision and re-revision surgery, and the use of TM cups provided longstanding stability.

Summary: This study provides comprehensive long-term outcomes of using TM augments for severe acetabular defects, with an estimated mean implant survivorship of 8.99 years. Despite some complications during surgery, the quality of life and joint function of patients were significantly improved postoperatively.

Summary: In this study, a novel porous tantalum (pTa) trabecular bone metal plate was prepared by depositing tantalum on porous silicon carbide (SiC) scaffolds using chemical vapor deposition technology. The function of the novel bone plate was evaluated in an animal fracture model. The results showed that the pTa trabecular bone metal plate was effective in fracture fixation and promoted new bone formation and integration with the host bone. Therefore, this novel pTa trabecular bone metal plate has good prospects for application in treating fractures.

Summary: Total hip arthroplasty (THA) is being performed more frequently in young patients, leading to an expected increase in revision surgeries. Impaction bone grafting (IBG) with morselized allograft is a viable option for treating bone loss. Several studies have reported satisfactory medium- and long-term results.

Summary: Classification and evaluation of acetabular defects are challenging due to the lack of quantitative techniques. This study introduces a new method based on statistical shape models to quantitatively describe acetabular defects encountered during revision total hip arthroplasty. The developed approach could lead to automated and unbiased classification methods, as well as provide a basis for designing new acetabular implants based on clinical variation in acetabular defects.
