Cancer tumours or osteoporosis.
Causes of pathological fractures. Other diseases can also lead to pathologic fractures. Some of these include. Noncancerous tumors and cysts.
Pagets disease of bone a rare condition that causes unusual bone structure. Pathologic fractures occur through areas of weakened bone attributed to either primary malignant lesions benign lesions metastasis or underlying metabolic abnormalities with the common factor being altered skeletal biomechanics secondary to pathologic bone. The word pathological means caused by a disease and the word fracture means a break in the continuity of the bone.
A pathological fracture occurs when the bone breaks in an area by a small trivial force or even casually that was already weakened by some other disease. A pathological bone fracture is a bone fracture which occurs without adequate trauma and is caused by a preexistent pathological bone lesion. Causes include resorption of bone mass osteoporosis reduction of bone quality osteomalacia osteonecrosis insufficient bone production osteogenesis imperfecta fibrous dysplasia augmented bone.
A pathological fracture occurs when a bone breaks due to a weakness in the structure caused by an abnormality or disease process. Causes of bone abnormalities include osteoporosis malignant or non-malignant tumors infection and some inherited bone disorders. Pathological fractures are when a fractures occurs through a bone which has already been weakened by a generalized or localized skeletal disorder it is called pathological fracture.
It is same like traumatic fractures these fractures take place either spontaneously or. Pathological fractures are fractures that occur in abnormal bone and occur spontaneously or following minor trauma that would not otherwise fracture biomechanically normal bone. Terminology The term pathological fracture is usually reserved for.
The commonest causes of pathological fracture are osteoporosis and osteomalacia. 13 Fracture patterns and their significance. Hair-line fractures result from minimal trauma ie.
Trauma which is just great enough to produce a fracture but not severe enough to produce any significant displacement of the fragments. Such a fracture most commonly occurs as a result of a twisting injury. Pathological fractures Fractures occur in bone which have been weakened already due to a pathological process.
Causes of pathological fractures can be classified into generalised bone conditions or local benign causes General bone conditions Osteogenesis imperfecta. When there is pathologic fracture through the lytic lesion bleeding can occur due to early fracture callus. Thus these fractures should be stabilised first and then biopsy undertaken.
Biopsy should be obtained from a site near but unaffected by fracture. Site should be as small as possible longitudnally in line with the extremity. Is this a pathologic fracture and if so which category of pathologic fracture which bone which side and which episode of care.
This patient suffered a pathologic fracture of the L-3 vertebra due to age-related osteoporosis Gold says. This occurs when an underlying condition weakens the bone and causes a fracture. Here at least one part of the bone twists during a break.
A cause of pathological fracture. A 62 year old woman presented to the emergency department after having a fall at home. She had left hip pain but was not clinically dehydrated or disorientated.
On further examination her left leg was shortened and externally rotated indicative of a fracture. Her history included type 2 diabetes depression. Osteoporosis is the most common cause of pathological fractures.
High force is required to fracture a normal bone but diseased bones may fracture as a result of low impact trauma. A fracture arising within abnormal bone is termed pathological. Osteoporosis is the commonest cause of pathological fractures.
Osteoporosis is the commonest cause of pathological fractures in the elderly. The fracture is managed as any other however the following points must be considered. The patient is often elderly and must be mobilized as soon as possible.
ORIF is usually necessary. Fractures can also cause due to pathological conditions like a disease or deficiency. Fractures occurred due to such conditions are known as pathological fractures and one of the most common causes is osteoporosis.
Certain pathological conditions result in the weakening of bones and that reduces their weight or pressure-bearing ability. Pathological fractures In the presence of disease ie. Cancer tumours or osteoporosis.
Patterns of fractures generally indicate the cause and will usually dictate the method of reduction. Transverse fractures A transverse fracture through a long bone can be result of an angulation force. As a general rule a pathological fracture is one caused by minor trauma that typically would not cause the type of fracture observed.
The discovery of a pathological fracture can be a cause for concern because it may be the first sign of an underlying pathology focal or systemic benign or malignant and it is often discovered in an emergency setting.
