![]() Discussion: This patient presents a sub-capital fracture of his femoral neck, associated to osteonecrosis of the femoral head. The management of this condition can vary from a conservative management to a surgical management with total hip arthroplasty, depending on patient’s clinic and the extension of his necrotic lesion. The fractures associated to femoral head osteonecrosis are very rare, being the subchondral portion the site with a higher compromise, and the junction between the necrotic bone and the bone under remodeling process another site of potential fracture. Introduction: The osteonecrosis of femoral head is a progressive and devastating condition for the prognosis of the coxofemoral joint, with an increase in its prevalence and an etiology of multifactorial nature, and with compromise specially in young or middle age (20 to 40 years of age) patients.

In a pathological compression fracture of a spinal vertebra fractures will commonly appear to collapse the entire body of vertebra. Pathological fractures present as a chalkstick fracture in long bones, and appear as a transverse fractures nearly 90 degrees to the long axis of the bone. This definition arises because a normal human being ought to be able to fall from standing height without breaking any bones, and a fracture, therefore, suggests weakness of the skeleton. There are three fracture sites said to be typical of fragility fractures: vertebral fractures, fractures of the neck of the femur, and Colles fracture of the wrist. Only a small number of conditions are commonly responsible for pathological fractures, including osteoporosis, osteomalacia, Paget's disease, Osteitis, osteogenesis imperfecta, benign bone tumours and cysts, secondary malignant bone tumours and primary malignant bone tumours.įragility fracture is a type of pathologic fracture that occurs as a result of an injury that would be insufficient to cause fracture in a normal bone. ![]() This process is most commonly due to osteoporosis, but may also be due to other pathologies such as cancer, infection (such as osteomyelitis), inherited bone disorders, or a bone cyst. ![]() Pathological fracture of the humerus in a patient with metastasis of renal cell carcinomaĪ pathologic fracture is a bone fracture caused by weakness of the bone structure that leads to decrease mechanical resistance to normal mechanical loads.
