Patients with peri-acetabular osteolysis around a well fixed cementless acetabular component may be treated with liner exchange. When the locking mechanism is unreliable or unavailable, cementing the liner into the fixed acetabular component is a feasible option. The purpose of this study was to evaluate the clinical and radiographic long term results of this technique. Forty hip revisions with liner cementation in 37 patients were performed. The minimum follow up was 10 years. Modified Harris Hip Score and recent x rays were reviewed. Four hips were re-revised. Two patients were diagnosed with exacerbation of osteolysis but refused revision. Dislocation rate was relatively high (16%). Liner cementation technique in revision hip surgery is useful in patients with a well fixed metal backed acetabular component.

Low rates of dislocation and reoperation following robotic-assisted total hip arthroplasty for femoral neck fracture.

Introduction: Total hip arthroplasty (THA) is widely used for active, elderly patients with femoral neck fractures (FNF). Compared to THA for osteoarthritis, THA for FNF is associated with a higher incidence of dislocation and reoperation. Robotic assistance may improve component positioning and leg-length restoration in THA, but its use in FNF has not been described.

Accurate acetabular component positioning is crucial for the success of total hip arthroplasty (THA). Malplacement of the acetabular component increases the risk of post-surgery complications, most notably dislocation.1 Furthermore, malposition can also result in wear of the polyethylene liner, limited range of motion, and osteolysis.

Case: Triple pelvic osteotomy (TPO) is used to treat developmental dysplasia of the hip in a pediatric population. This case report highlights a new indication for this procedure. Acetabular coverage was restored in a 9-year-old patient who experienced instability following hip hemiarthroplasty and proximal femur composite allograft implantation for the treatment of Ewing sarcoma.

Background: Dual mobility (DM) implants in total hip arthroplasty provide excellent range of motion with low dislocation rates. A complication of this design is intraprosthetic dislocation (IPD), where the polyethylene (PE) liner dissociates from the femoral head. In older designs, IPD occurred due to a small head size and late PE wear with head-capture-mechanism failure.

Introduction: Total hip arthroplasty (THA) is recognized as one of the most effective surgical procedures for the treatment of end-stage hip arthritis. However, the increasing number of primary THA cases has led to a corresponding rise in the frequency of revision surgeries, which are often more complex and challenging due to severe acetabular bone loss. In such cases, managing Paprosky type 3A and 3B defects requires precise implant design and advanced surgical techniques.
