Fibular Stress Fracture
- Fibular Shaft Stress Fracture
- Stress Fracture of the Fibula
- This page refers to stress fractures of the Fibula, an overuse injury
- Acute Fibular Fractures are discussed separately
- Incidence in athletes and military recruits is reported to range from 3.5% ‐ 29.6%, depending on the population
- Kahanov et al: proportion of fibular stress fractures among runners to be 7% ‐ 12% of all stress fractures
- However, the proportion may be as high as 33% and 20% of stress fractures in female and male distance runners, respectively
- See: Stress Fractures (Main)
- The vast majority occur in the distal 1/3 of the fibula
- May be overlooked initially
- Proximal 1/3rd is much less common
- Proposed mechanism
- Compression loading
- Shear fatigue
- Biceps Femoris contraction stresses
- Proximal third potential etiology
- See: Stress Fracture Risk Factors
- Sports (proximal third) described in
- Fractures & Dislocations
- Muscle and Tendon Injuries
- Pediatric Considerations
- History of overuse
- Pain with activity only can progress to pain at rest
- Physical Exam: Physical Exam Leg
- Point tenderness along fibula
- Special Tests
- Standard Radiographs Tibia Fibula
- Initial imaging modality of choice
- Early Findings
- Lag behind clinical exam for weeks
- May demonstrate subtle radiolucency, poor definition of the cortex
- Late findings
- Thickening and sclerosis of the endosteum
- Periosteal new bone formation
- Gold standard for stress fractures of the tibia
- More sensitivity than XR
- Helps to differentiate stress fracture from shin splints
- Role in evaluating stress fractures is not well defined
- Not applicable
- Proximal fibula stress fractures
- More common in military recruits
- May have a longer recovery period
- Distal fibula stress fractures
- Typically resolve with appropriate nonoperative management
- Vast majority of fibular stress fractures
- Activity modification
- Initially, athlete must discontinue all sporting activity
- Non weight bearing with Crutches
- Strongly consider with athletes who have pain while walking
- When pain with ambulation resolves, can ween off crutches
- Physical Therapy
- For proximal stress fractures, consider stretching Biceps Femoris
- Failure of conservative measures
Rehab and Return to Play
- Delayed Union
- Delayed return to sport
- Physical deconditioning
