Essentials of Diagnosis
++
Internal rotation of the hip is the best provocative diagnostic maneuver
Hip fractures should be surgically repaired as soon as possible (within 24 hours)
Delayed treatment of hip fractures in the elderly leads to increased complications and mortality
+++
General Considerations
++
Approximately 4% of the 7.9 million fractures that occur each year in the United States are hip fractures
Risk factors
Osteoporosis
Female sex
Height > 5-foot 8-inches
Age over 50 years
Usually occur after a fall
High velocity trauma is needed in younger patients
Stress fractures can occur in athletes or individuals with poor bone mineral density following repetitive loading activities
++
Pain in the groin is typical, but pain may radiate to the lateral hip, buttock, or knee
If a displaced fracture is present, the patient will not be able to bear weight and the leg may be externally rotated
Patients with hip stress fractures have less pain on physical examination but typically have pain with weight bearing
++
Radiographic views include anteroposterior views of the pelvis and bilateral hips and frog-leg lateral views of the painful hip
CT scan or MRI may be necessary to identify the hip fracture pattern or to evaluate non-displaced fractures
+++
Diagnostic Procedures
++
The Trendelenburg test can be performed to examine for weakness or instability of the hip abductors, primarily the gluteus medius muscle (eTable 41–3)
Another functional test is asking the patient to hop or jump during the examination
