Case Study
The article presents the case study of seventy-four-year-old man who had a painful nonunion of femoral neck fracture nine months after in situ pinning, and was treated with hybrid total hip arthroplasty. In this case report, the focus was on a retrieved cobalt-chromium alloy femoral head with an apparent protrusion in its main weight-bearing region, which contributed to the observed damage to the surface of the highly cross-linked ultra-high molecular weight polyethylene counter bearing.

    Background: Hip arthroplasty for the treatment of nonunion at the site of a femoral neck fracture has provided good short-term results. The purpose of the present study was to evaluate the long-term results and complications of total hip arthroplasty for the treatment of femoral neck nonunion....

    We report a case of a varus malunited periprosthetic femoral neck fracture following metal-on-metal hip resurfacing operation. Failure to closely observe and poor compliance in the young and active group of patients may contribute to such an unfavourable outcome.

    Background: Recent randomized, controlled trials performed at two years postoperatively have shown that a primary total hip replacement is superior to internal fixation for the treatment of a displaced femoral neck fracture in a relatively healthy, mentally competent, elderly patient. The...

    Purpose: Internal fixation versus joint replacement for treating intracapsular hip fractures is still a major debate. The Targon® FN fixation concept is innovative; two small case series are promising. We present the first larger series. Methods: We conducted prospective documentation of all...

    We report a case in which cement protrusion into the pelvis led to a major complication. During reaming and preparation of the anterosuperior acetabulum, a bony defect resulted which made fixation of an uncemented cup impossible, and a cemented polyethylene cup was used instead. After surgery...

    The article discusses research being done on the role of hip distraction arthroplasty in the treatment of adolescent patients with avascular necrosis of the femoral head. It references a study by Michael G. Vitale and colleagues presented at the 75th Annual Meeting of the American Academy of...

    Accurate reproduction of the femoral anteversion is important in achieving stability of the prosthetic joint in total hip arthroplasty (THA), while placement of the femoral stem in excessive anteversion or retroversion results in an increased incidence of dislocation. Due to a number of factors,...

    The conversion of previous hip surgery to total hip arthroplasty creates a durable construct that is anatomically accurate. Most femoral components with either cemented or cementless design have a fixed tapered proximal shape. The proximal femoral anatomy is changed due to previous hip surgery...

    Revision hip arthroplasty can sometimes be very challenging due to poor proximal bonestock following multiple revisions, bone resorption, infection or peri-prosthetic fracture. The challenge for the surgeon is to achieve fixation of the implant distally in healthy bone, yet allow bone in-growth...
