Sheep hips have a natural non-spherical head similar to a cam-type deformity in human beings. By performing an intertrochanteric varus osteotomy, cam-type femoroacetabular impingement can be induced experimentally. In sheep, the aspherical portion is located superiorly - exactly matching the region where the superior retinacular vessels enter the femoral head-neck junction in human beings. In order to fully exploit the potential of this experimental FAI model, a safe osteochondroplasty of the superior asphericity would need to be done without the risk of avascular necrosis...

This research focuses on femoral head wedge resection for the treatment of avascular necrosis (AVN) of the femoral head. A 9-year-old girl presented to the emergency room complaining of right hip pain that occurred after a pedestrian car accident. After 8 months of internal fixation using cannulated screws for Delbet-type 2 fracture of the femoral neck, AVN of the femoral head developed in the patient. Even though valgus-derotation-extension intertrochanteric osteotomy was performed for the treatment of AVN, it progressed further and femoral head wedge resection was performed to recover the femoral head sphericity...

PURPOSE: Short-stem hip arthroplasty has the potential advantage of femoral bone stock preservation, especially in view of the expected revisions in the often relatively young patients. Despite short-stem hip prosthesis are increasingly used for total hip arthroplasty, there are no sufficient mid- and long-term results especially for patients with avascular femoral head osteonecrosis. The present study investigates mid-term functional results as well as the revision rate following implantation of a short-stem prosthesis...

Although musculoskeletal pain in patients with sickle cell disease (SCD) is most frequently the result of vaso-occlusive episodes, clinicians often consider other etiologies including osteomyelitis, avascular necrosis, and trauma. In this study, we report the case of a young female with SCD with hip and back pain secondary to a nontraumatic iliopsoas periosteal hematoma with evidence of adjacent bone infarction. The pathophysiology, diagnostic considerations, and management of periosteal hematomas in SCD are reviewed...

Background: Sickle cell trait is usually an asymptomatic presentation of a patient with slightly different hemoglobin molecule makeup than normal. It is similar to a more serious disease, sickle cell disease, in which a person's hemoglobin is mutated in such a way that causes their red blood cells to easily change shape in certain environmental and internal states; this causes red blood cells to adhere to the walls and occlude the lumen of the arteries in which they travel, leading to downstream effects secondary to ischemia...

BACKGROUND: Most orthopedic surgeons prefer spica cast immobilization in children for 4 to 12 weeks after surgical hip reconstruction in children with developmental hip dysplasia. This challenging treatment may be associated with complications. Studies are lacking that focus on early mobilization without casting for postoperative care after hip reconstruction. METHODS: Twenty-seven children (3.4±2.0 years), including 33 hips with developmental hip dysplasia (DDH) and dislocation of the hip (Tönnis grade 1 to 4), who underwent hip reconstruction (Dega acetabuloplasty, varisation-derotation osteotomy and facultative open reduction) were retrospectively included in this study...

The immunosuppressive regimens required for hematopoietic stem cell transplantation predispose recipients to complications, including avascular necrosis. Cancer-related comorbidities, immunosuppression, and poor bone quality theoretically increase the risk for perioperative medical complications, infection, and implant-related complications in total joint arthroplasty. This study reviewed 20 primary total hip arthroplasties for avascular necrosis in 14 patients. Outcomes were assessed at routine clinical visits and Harris hip scores were calculated...
