Femur Fracture Clinical Presentation

History
History usually is obvious in cases of femoral diaphyseal fractures. Typically, patients describe a significant force applied to the extremity. Significant pain and deformity are reported as well.
Physical
- Conduct a thorough examination to rule out associated injury. Hip fractures and ligamentous knee injuries commonly are observed in association.[5]
- At the site of fracture, tenderness on examination and visible deformity typically are noted.
- The extremity may appear shortened, and crepitus may be noted with movement.
- The thigh is often swollen secondary to hematoma formation.
- Perform a thorough vascular examination on the extremity. Signs of vascular compromise should prompt arteriography and a vascular surgery consult. Physical signs of arterial injury include the following:
- Expanding hematoma
- Absent or diminished pulses
- Progressive neurologic deficits in a closed fracture
- Because of extensive blood supply to the musculature surrounding the femur, diaphyseal fractures may be associated with significant blood loss (ie, 1 L or more) and resulting tachycardia and hypotension.
- Test distal neurologic function, though examination is frequently unreliable because of the amount of pain associated with these fractures. Nerve injury is rare because of protective surrounding musculature.
Causes
- Trauma
- Lytic lesions
- Cancerous metastasis
- Paget disease
- Bone cysts
