Background
Clinical Features
- Greater Trochanter
- Via direct trauma (older patients) or avulsion injury (adolescents)
- Hip pain that increases with abduction; tenderness over greater trochanter
- Lesser Trochanter
- Via avulsion due to forceful contraction of iliopsoas (adolescents) or pathologic bone
- Pts are usually ambulatory; c/o pain in groin worse w/ flexion
Differential Diagnosis
Femur Fracture Types
Proximal
- Intracapsular
- Extracapsular
Shaft
- Mid-shaft femur fracture (all subtrochanteric)
Diagnosis
- Consider AP pelvis in addition to AP/lateral views to compare contralateral side
- Consider MRI if strong clinical suspicion but negative x-ray
Management
- Treatment for both types:
- Non-weight bearing with ortho f/u in 1-2wk
Disposition
- Outpatient
