CAM Boot for Non-Displaced Distal Fibula Fractures
Treatment Rationale
- Non-displaced distal fibula fractures can be successfully managed non-operatively with immobilization devices that provide adequate ankle stability, as recommended by the American College of Rheumatology, in patients with this type of fracture 1, 2
Critical Implementation Details
- The boot must be in close contact with the entire foot and lower limb to provide adequate immobilization, according to the Diabetes/Metabolism Research and Reviews guidelines, for optimal fracture healing in patients with non-displaced distal fibula fractures 3
- Insoles should accommodate any foot deformity safely and provide pressure redistribution to prevent skin breakdown, as suggested by the Diabetes/Metabolism Research and Reviews, in patients using a CAM boot for non-displaced distal fibula fractures 3, 4
Common Pitfalls to Avoid
- Monitor for skin breakdown carefully, as improperly fitted boots can cause ulceration in up to 14% of cases, particularly in patients with sensory neuropathy or diabetes, according to the Diabetes/Metabolism Research and Reviews guidelines, for patients with non-displaced distal fibula fractures 3, 4
- Ensure patient understanding of adherence importance, as removable devices have a median 3-month longer time to healing when patients don't wear them consistently, as reported by the Diabetes/Metabolism Research and Reviews, in patients with non-displaced distal fibula fractures 4
Follow-Up Protocol
- Obtain repeat radiographs at 10-14 days to ensure fracture position is maintained, as recommended by the Praxis Medical Insights, for patients with non-displaced distal fibula fractures, although this fact is also supported by other guidelines 5
- Typical immobilization duration is 3-6 weeks depending on fracture healing progression and patient factors, according to the Annals of the Rheumatic Diseases guidelines, for non-displaced distal fibula fractures 1, 2
