A bone fracture is termed pathologic when the fracture occurs through a region of a preexisting bone pathology weakening the bony architecture. Such pathologies include metabolic bone diseases such as Paget’s disease, osteogenesis imperfecta, and osteoporosis as well as local alterations of the bone structure due to tumorous processes. Metabolic bone diseases are a diverse group of diseases that result in abnormalities of (a) bone mass, (b) structure mineral homeostasis, (c) bone turnover, or (d) growth. Osteoporosis, the most common metabolic bone disease, results in generalized loss of bone mass and deterioration in the bone by: In clinical terms, metabolic bone diseases may result in bone pain and loss of height (due to compression of vertebrae), and they predispose patients to fractures. Metabolic diseases of bone often affect bone density. For example, persons with osteoporosis experience a significant decrease in .
A pathologic fracture is a broken bone that’s caused by a disease, rather than an injury. Some conditions weaken your bones, which makes them more likely to . 3) Connective tissue bone disease- eg. Osteogenesis imperfecta. Metabolic Bone Disease: Normal bone growth and mineralization requires adequate calcium and phosphate. There are numerous etiologies of rickets, including nutritional deficiencies (calcium, phosphate and vitamin D), drug induced, renal pathology, and tumours.

A ____runs at a right angle to the long axis of a bone and most commonly results from a direct blow or is a fracture within pathologic bone. oblique fracture An____runs a course of approximately 45 degrees to the long axis of the bone and is caused by angulation or by both angulation and compression forces.
Metabolic bone diseases (MBDs), of various origins, are the most common causes of lameness, skeletal, and spinal abnormalities in lizards. MBDs can manifest as fibrous osteodystrophy, osteomalacia, osteoporosis, osteopetrosis, pathologic fractures, and more (see Chapter ). The focus is not limited to a particular cause of pathologic fractures, as in other books on osteoporosis and Paget's disease. Nor is it limited primarily to a discussion of the orthopedic surgical. Objective: To determine whether metabolic bone disease plays a role in the cause of femoral neck stress fractures. Study design: Twenty-three patients with femoral neck stress fractures were enrolled prospectively in the study. Examination included computed tomography bone densitometry, trace mineral analysis, and histomorphometric analysis of the iliac crest in thirteen patients who underwent. anagement of pathologic long bone fractures differs from that of fractures of disease-free bone. The primary surgical goal is restora-tion of anatomic limb length, align-ment, and rotation by creating a sta-ble construct that allows early motion and weight bearing. Unlike tumor-free bone, pathologic frac-tures typically occur in the setting of.
