Stainless-steel screws are commonly used for fragment fixation during periacetabular osteotomy (PAO) at our institutions. Titanium is reserved for patients with documented nickel allergies. Titanium screws possess a significantly lower Young's modulus than stainless steel and, therefore, potentially less resistance to physiologic loading.

Fluoroscopic images pose a radiation risk to operating room staff, scrubbed personnel, and the patient. Most commonly, a Standard Fluoroscope with an Image Intensifier is used.

We compared radiographic and clinical outcomes among patients who were treated with closed reduction (CR), open reduction (OR), and open reduction with concomitant pelvic osteotomy (ORP) for the treatment of a dislocated hip. We sought to identify the optimal age at treatment within each of these groups.
View Article and Find Full Text PDFPeriacetabular Osteotomy (PAO) is a well-established surgical intervention for the treatment of hip dysplasia. Our primary objective was to assess whether a group of young flexibility athletes who underwent PAO for hip dysplasia recovered their pre-operative hip range of motion (ROM) within 1 year of surgery. Our secondary objective was to compare hip ROM recovery between a group of young flexibility athletes and a group of non-flexibility athletes who underwent PAO for hip dysplasia.

Due to compromised bone quality after irradiation, spinal fusion has a high failure rate. The aim of this study was to evaluate treatment of post-laminectomy and post-irradiation kyphosis in children using a vascularized rib graft (VRG) to augment anterior spinal fusion and posterior spinal fusion.

These procedures treat the proximal femur, the acetabulum, or both, and most surgeons endorse the same surgical option regardless of an individual patient's anatomy. This "one-surgery-fits-all" approach fails to consider potential variations in baseline anatomy that may make one option more sensible than another.

However, it is unclear how radiographic measures may be affected using EOS. The present study aims to determine the reproducibility of measures of acetabular morphology on EOS images as compared with CR, and to directly compare the 2 imaging modalities.
View Article and Find Full Text PDFBackground: The Bernese periacetabular osteotomy (PAO) is one of the most-used surgical techniques to treat symptomatic acetabular dysplasia. Although good functional and radiographic short-term and long-term outcomes have been reported, several complications after PAO have been described. One complication that may compromise clinical results is nonunion of an osteotomy.
View Article and Find Full Text PDFPelvic osteotomies are used for hip preservation in children and young adults to improve femoral head coverage and stabilize the hip joint. Redirectional osteotomies aim to reduce the overall volume and redirect the acetabulum. These include Salter, Pemberton, Dega, and San Diego osteotomies.
