Osteonecrosis of the femoral head (ONFH) results in collapse of the femoral head and rapid destruction of the hip joint. The repair of post-collapse articular cartilage and subchondral bone is challenging. We interrupted the blood supply to the femoral head and established a full-thickness articular defect animal model after ONFH was determined via X-ray. Read More

Introduction: Surgical management of patients with sickle cell disease (SCD) poses a unique challenge to orthopaedic surgeons due to increased operative and perioperative risk. Studies evaluating perioperative complications among patients with SCD undergoing orthopaedic surgery have been limited. We sought to review the clinical characteristics and perioperative complications in our patients with SCD who required orthopaedic surgery. Read More

Background: Based on several attributes involved in bone formation, bone marrow-resident mesenchymal stem cells (MSCs) have been employed in the treatment of patients suffering from femoral head osteonecrosis. Due to the low content of MSCs in the bone marrow, ex vivo expansion procedures are utilized to increase the cell number. Customarily, before administration of the resulting expanded cell product MSCs to the patient, its cellular identity is usually evaluated according to a set of "minimal phenotypic" markers, which are not modified by ex vivo processing.

Background: Pelvic resections are challenging, and reconstruction of the resected acetabulum to restore mobility and stability is even more difficult. Extracorporeal radiation therapy (ECRT or extracorporeal irradiation) of autograft bone and reimplantation allows for a perfect size match and has been used with some success in the extremities. Although the risk of wound complications in pelvic surgery has discouraged surgeons from using ECRT of autografts in that anatomic site, we believe it may be a reasonable option. Read More

Background: The incidence of bilateral corticosteroid-induced osteonecrosis of the femoral head (ONFH) is high. Although the precise mechanism of corticosteroid-induced ONFH development is unclear, hepatic enzyme abnormalities such as low activity of hepatic cytochrome P450 3A could be one cause.

Subchondral insufficiency fracture (SIF) is a non-traumatic condition that has historically been associated with elderly, osteoporotic women and patients with systemic conditions. There has been much work done to determine the pathogenesis of SIF, which has previously been regarded as idiopathic, rapid-progressive osteoarthritis or osteonecrosis of the hip, spontaneous osteonecrosis of the knee (SONK), osteochondral defect (OCD) of the talus and adult-onset Freiberg infraction of the metatarsal head. Early diagnosis and management are crucial to prevent subchondral collapse, secondary osteonecrosis and early-onset osteoarthritis. Read More

Background: It has been well known that the degeneration of hip articular cartilage with osteonecrosis of the femoral head (ONFH) increases the instability of hip and accelerates the development process of ONFH. A better understanding of the expression of chondrogenesis-related and arthritis-related genes of cartilage along with the progression of ONFH seems to be essential for further insight into the molecular mechanisms of ONFH pathogenesis.

Methods: We analyzed the differentially expressed gene profile (GSE74089) of human hip articular cartilage with ONFH. Read More

Introduction: The pathophysiology of rapidly progressive hip disease is still unclear. It is a rare subset of osteoarthritis that mainly affects elderly women and presents with new- onset severe hip pain and dysfunction. It is assumed to be triggered by extremely rapid osteoarthritic changes resulting in impaction of the femoral head into the acetabulum, with successive osteonecrosis and insufficiency of the femoral head.
