Avascular Necrosis (AVN) of the Femoral Head - Case Based Discussion
Introduction Avascular necrosis (AVN) of the femoral head, also known as osteonecrosis, is a condition characterized by death of bone tissue due to interruption of blood supply to the femoral head. The femoral head is particularly vulnerable to ischemia because its vascular supply is limited and largely dependent on the retinacular vessels arising from the medial circumflex femoral artery. Loss of blood supply leads to necrosis of trabecular bone and marrow, resulting in structural collapse of t...
Open topicComminuted Intertrochanteric Femur Fracture - Case Based Discussion
Introduction Intertrochanteric fractures are extracapsular fractures occurring between the greater and lesser trochanter of the proximal femur. These injuries are common in the elderly population following low-energy falls but may also occur in younger patients following high-energy trauma. The fracture pattern may range from simple two-part fractures to highly comminuted unstable fractures with loss of posteromedial and lateral wall support. Comminuted intertrochanteric fractures are considered...
