Medial hinge disruption >2 mm, anatomic neck fracture, head-splitting → high AVN risk. Assists decision towards arthroplasty in ischemic patterns.
Introduction Avascular necrosis (AVN) of the femoral head, also known as osteonecrosis, is a condition characterized by death of bone tissue due...
Case Presentation A 40-year-old male presented with progressive pain in the right hip for the past one year. The pain was initially mild but grad...
