Syndesmosis is the ligament linking the 2 bones of the leg. Once this ligament is damaged, it often arises together with other ankle injuries such as fractures and sprains.
In general, if the injury is not treated, the outcome is poor. It is important to note that the ankle joint is in correct alignment by the ends of the fibula and tibia which wraps around the external and inner side of the ankle. Remember that once there is damage, the joint might become unstable.
A syndesmosis injury occurs if there is outward twisting of the foot. This injury manifests if the ankle is twisting externally or if the foot and the leg twists inwards while on the ground.
What are the indications?
A syndesmosis injury often arises along with ankle injuries. If an individual ends up with an ankle sprain or fracture, it requires assessment for possible damage to the ligament.
The general signs of an injury include the following:
- Ankle pain, usually the upper region
- Calf pain
- Inability to place any weight on the leg
The doctor requires an X-ray if an injury is likely. A stress X-ray is often needed. During the test, the doctor places force on the ankle to check if there is movement.
What are the types of syndesmosis injury?
Generally, the prevalent form of syndesmosis injury is a high ankle sprain. This injury involves damage to the ligaments above the ankle joint. The treatment is based on the stability of the ankle. Furthermore, if an X-ray reveals a stable joint, the treatment involves immobilization and crutches. Recovery is within 6-8 weeks.
If unstable, the treatment aims on keeping the ligament in a stable position as it heals. This requires a cast for protection or surgery to stabilize the ankle joint.
In some instances, an injury can occur with ankle fractures. If the damage due to a fracture, the doctor performs surgical intervention to reinstate the steadiness of the ankle joint. Surgery fixes the fracture or stabilizes the injury but oftentimes both are necessary.
