Randomized Controlled Trial Clinical TrialComparison of internal fixation with total hip replacement for displaced femoral neck fractures. Randomized, controlled trial performed at four years.
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 primary aim of the present study was to evaluate the outcomes at four years. ⋯ Compared with internal fixation, primary total hip replacement provides a better outcome for mentally competent elderly patients with a displaced femoral neck fracture. The complication and reoperation rates were significantly lower and hip function and health-related quality of life were at least as good at four years after the surgery.

Cervicothoracic extension osteotomy for chin-on-chest deformity in ankylosing spondylitis.
Chin-on-chest deformity is a disabling manifestation of ankylosing spondylitis. Surgical treatment consists of extension osteotomy at the cervicothoracic junction. The purpose of this study was to characterize the clinical presentation of this deformity and to determine the long-term functional and radiographic outcomes of treatment. ⋯ Extension osteotomy can reliably improve sagittal alignment and horizontal gaze as well as decrease neck pain, eating difficulties, and neurologic abnormalities. Internal fixation is recommended to prevent subluxation, delayed union, nonunion, loss of correction, or neurologic injury. There is a risk of death or catastrophic neurologic injury from the procedure.

Proximal femoral replacement for the treatment of periprosthetic fractures.
A periprosthetic fracture around the femoral component is a rare but potentially problematic complication after total hip arthroplasty. Reconstruction can be challenging, especially when severe bone stock deficiency is encountered. Proximal femoral replacement is one method of treating the severely deficient proximal part of the femur. The present report describes the outcomes of revision total hip arthroplasty with use of a proximal femoral replacement in a cohort of patients who had a Vancouver type-B3 periprosthetic fracture. ⋯ Despite a relatively high complication rate, we believe that proximal femoral replacement is a viable option for the treatment of periprosthetic fractures in older patients with severe bone deficiency. If a proximal femoral replacement is used, the stability of the hip must be tested diligently intraoperatively and a constrained acetabular liner should be utilized if instability is encountered. In order to enhance the bone stock, the proximal part of the femur, however poor in quality, should be retained for reapproximation onto the implant.
