Indications for Distraction Subtalar Arthrodesis (DSAA)
Distraction subtalar arthrodesis (DSAA) is a surgical procedure that can help alleviate severe flatfoot deformity, a condition that occurs when the arch of the foot collapses. While non-surgical treatments like orthotics and physical therapy may be beneficial, DSAA is often the recommended course of action when these measures fail to provide adequate relief.
Flatfoot deformity can arise from various causes, including genetics, ligament laxity, or trauma. As the arch of the foot flattens, it can cause pain, discomfort, and difficulty walking. The condition can also lead to ankle instability and heel spurs, further exacerbating the problem.
DSAA aims to address the underlying structural issues causing the flatfoot deformity. It involves fusing the bones within the subtalar joint, located beneath the ankle joint. This fusion corrects the abnormal alignment of the foot, restoring the arch and alleviating pain and discomfort. DSAA is typically recommended for individuals with severe flatfoot deformity that has not responded to conservative treatments and is significantly impacting their quality of life.
Distraction Subtalar Arthrodesis (DSAA) Procedure: A Step-by-Step Guide
Distraction subtalar arthrodesis (DSAA) is a surgical procedure that can effectively treat severe flatfoot deformity. By fusing the subtalar joint, DSAA can restore alignment, improve mobility, and alleviate pain in the foot and ankle.
Surgical Procedure
Incision and Approach
The DSAA procedure begins with a curved incision along the outer ankle. This incision allows the surgeon to access the subtalar joint, which connects the heel bone (calcaneus) to the talus bone (ankle bone).
Cartilage Removal
Once the joint is exposed, the surgeon carefully removes the cartilage from the surfaces of the calcaneus and talus. Cartilage is a slippery tissue that lines the joint and allows bones to move smoothly. Removing the cartilage creates a raw surface that will encourage bone fusion.
Spacer Insertion
A spacer, usually made of metal or bone, is then inserted between the calcaneus and talus. This spacer acts as a temporary wedge, distracting or separating the bones. Distraction is necessary because it creates space for new bone to form and bridge the gap between the calcaneus and talus.
Bone Distraction
After the spacer is in place, an external fixator (frame) is attached to the outside of the leg. The fixator is connected to pins that are inserted into the calcaneus and talus. Slowly and gradually, the pins are moved apart using the fixator. This distraction process continues over several weeks, allowing new bone to form in the gap between the calcaneus and talus.
DSAA is a complex and highly specialized surgical procedure that can provide significant relief from the symptoms of severe flatfoot deformity. By distracting the subtalar joint and promoting bone fusion, DSAA can restore alignment, improve mobility, and alleviate pain.
