Ankle fusion surgery, also known as ankle arthrodesis, aims to alleviate pain and enhance functionality for individuals dealing with ankle arthritis. This degenerative condition arises from cartilage breakdown within the ankle joint, exacerbating discomfort upon movement. Through ankle fusion, the affected bones are merged into a single unit, restricting joint motion and therefore eliminating arthritic pain.
Candidates for ankle fusion typically present severe ankle arthritis unresponsive to conservative measures like anti-inflammatory medications, injections, or activity modifications. While these treatments offer temporary relief, ankle fusion becomes imperative when pain persists or function deteriorates significantly. Conversely, individuals with insufficient bone quantity, compromised blood supply, or severe nerve dysfunction may be unsuitable candidates for ankle fusion.
Surgical Procedure
Under anesthesia, surgeons access the ankle joint through carefully placed incisions, removing residual cartilage to ensure bony contact. Metal hardware, such as screws and plates, stabilize the ankle in the desired position, promoting bone fusion. Techniques may vary, including traditional incisions or minimally invasive approaches like arthroscopic surgery. Bone grafts may be employed to enhance fusion, sourced from areas like the pelvis, heel bone, or knee vicinity.
Recovery and Rehabilitation
Ice/Elevate: Right after the surgery, it's crucial to elevate the fused ankle to reduce swelling. Ideally, this entails keeping the ankle positioned above the heart level, achieved by lying down or sitting in a reclined position. Pain medication will be administered during this initial phase for comfort.
Weight bearing/Mobility: Patients are restricted from weight bearing for 6-12 weeks, depending on the circumstances. Patients will need mobility aids like crutches, knee scooter, iWalk or wheelchairs. Physical therapy aids in joint suppleness and eventual weight-bearing transition. Temporary home modifications may facilitate mobility and safety during recovery.
Risks and Complications
Potential complications, including anesthesia-related risks, infections, and nerve damage, underscore the importance of vigilant postoperative care. Nonunion, though relatively rare, poses a risk necessitating additional interventions to promote bone fusion. Long-term concerns encompass altered gait patterns and potential stress-induced arthritis in adjacent joints, necessitating ongoing monitoring.
Understanding ankle fusion surgery empowers individuals with informed decision-making and proactive rehabilitation strategies, fostering improved pain management and restored functionality in daily life.
