The ankle comprises three bones: the tibia, fibula, and talus. Fractures in the ankle typically involve the distal ends of the tibia and/or fibula, often affecting ankle ligaments. These fractures vary from minor avulsion injuries to severe, shattering breaks, commonly resulting from the ankle twisting inward or outward.
Symptoms
An ankle fracture may present with:
- Pain at the fracture site, extending from the foot to the knee
- Swelling, either localized at the ankle or along the leg
- Blisters, warranting prompt attention
- Bruising
- Impaired walking ability; however, walking isn't a reliable test for a fracture
- Open fractures with bone protrusion require immediate medical attention to prevent complications like infections.
Diagnosis
Due to potential overlap with severe ankle sprains, all ankle injuries should be evaluated by a physician. Diagnosis often involves X-rays to assess fracture type, bone involvement, and displacement.
Treatments
- Elevation and Ice: To reduce swelling and alleviate pain.
- Splint: Provides support and accommodates swelling. In some cases, realignment may be necessary.
- Rest/No Weight Bearing: Crutches, walkers, or wheelchairs help keep weight off the ankle until healing progresses.
- Cast/Fracture Boot: Immobilization aids healing. The choice between cast and boot depends on fracture type and physician's recommendation.
- Surgery (Open Reduction and Internal Fixation - ORIF): Required for displaced or complex fractures to restore alignment and minimize arthritis risk. Metal plates and screws stabilize the bones during healing.
Recovery
Healing progress is monitored with additional X-rays, ensuring bone alignment and ankle stability.
Risks and Complications
Complications are rare but more prevalent in diabetic patients and smokers. Rehabilitation and strengthening programs may be prescribed to prevent deformity or uneven leg length in children.
