From the Research
Treatment for a calcaneofibular ligament tear should prioritize conservative management, focusing on early rehabilitation and physical therapy to prevent chronic ankle instability and recurrent sprains, as supported by the most recent and highest quality study 1. The initial approach typically involves the RICE protocol: rest, ice, compression, and elevation. For mild to moderate tears, a period of immobilization using a walking boot or ankle brace for 2-6 weeks is recommended, depending on the severity of the injury. Pain management is crucial and can be achieved with NSAIDs like ibuprofen (400-600mg three times daily) or naproxen (500mg twice daily) for 1-2 weeks. Physical therapy should begin after the acute phase, focusing on:
- Range of motion exercises
- Proprioception training
- Progressive strengthening of the peroneal muscles Exercises should include:
- Ankle circles
- Alphabet tracing
- Balance exercises on unstable surfaces
- Resistance band work Complete rehabilitation typically takes 6-12 weeks. For severe tears or cases that don't respond to conservative treatment after 3-6 months, surgical repair may be necessary, as highlighted in a study on the role of calcaneofibular ligament injury in ankle instability 2. The calcaneofibular ligament is critical for lateral ankle stability, connecting the fibula to the calcaneus, and proper rehabilitation is essential to prevent chronic ankle instability and recurrent sprains. Patients should avoid returning to full activity until they have regained full strength, range of motion, and proprioception in the affected ankle, as emphasized by the importance of effective rehabilitation in preventing long-term consequences 1.
