Introduction:
Subtalar fusion is a process incorporated to correct rigid, painful deformities or instability of the subtalar joint or, more frequently, to eliminate arthritis, which turns painful for this joint. Subtalar fusion is frequently performed by doctors under general anesthesia (GA). The time taken for this surgical process is estimated to be around 90 minutes. This is frequently done in people with subtalar issues who typically complain of pain along the outer side of the foot just below the ankle. This process helps eliminate pain in the long term too.
What Is Subtalar Fusion?
The subtalar joint is a part of the ankle situated below the ankle joint, lying between the talus and the calcaneus (heel) bone. The primary function of the subtalar joint is to provide the side-to-side movement of the foot and ankle. This movement helps in walking, particularly on surfaces that are not even. Fusion surgery helps by locking the bones combined to heal as one. It is best advised for diseased joints which cannot be replaced. As a fusion heals together, it acts as one unit, restoring function and helping to relieve pain. A fusion is very long-lasting as well. Subtalar fusion is incorporated in people who experience rigid, painful deformities or instability of the subtalar joint or, more frequently for eliminating arthritis which turns painful for this joint. While performing surgery, the remaining cartilage in the joint between the talus bone above and the calcaneus bone below is extracted, and the joint surfaces are joined together with screws for positioning the bones in place while they are healing. The primary motive of subtalar fusion is to enhance functioning and reduce pain.
What Is the Process of Subtalar Fusion?
Subtalar fusion is a process frequently performed under general anesthesia. The time taken for this surgery is estimated to be around 90 minutes. The surgeon first makes an incision (cut) on the outer side of the ankle. The distorted joint surfaces are cleaned thoroughly and cleared, and the joints are fixed combinedly with the help of one or two screws by the back of the heel. The patient does not feel the screw, and it does not need to be removed. Subtalar fusion is sometimes done arthroscopically. Be sure to discuss what process will be used by the surgeon. The ankle needs to get a cast applied immediately after the completion of the surgery. The patient might have a small tube (drain) in the wound to drain any extra fluid present.
How Are Subtalar Problems Diagnosed?
People with subtalar problems frequently complain of pain in the outer side of the foot just below the ankle. Subtalar pain might be mistakenly regarded as ankle pain. Patients with subtalar joint problems frequently walk with difficulty, favoring the other painless foot, and experiencing swelling in this region. People frequently find difficulty while walking and experience pain while walking on surfaces that are not even and complain of stiffness in the foot. Subtalar fusion is considered important for three reasons frequently: for the correction of deformity, for the correction of instability, and for the correction of correct painful arthritis. Reasons for arthritis can be trauma, degeneration, rheumatologic conditions, and infections.
What Is the Treatment Plan in Subtalar Fusion?
The foot and ankle orthopedic surgeon will discuss treatment options before proceeding with a subtalar fusion. Skin problems in the area of the surgical site, poor overall health. Smoking can elevate the risk of blood clots, wound healing issues, and the possibility the fusion will not heal. People should eradicate nicotine use at least one month prior to the surgery and remain away from it until the fusion heals properly. People who have an inability or unwillingness to follow the treatment plan might not be a regarded as a good option for this surgery.
What Happens After Subtalar Fusion?
The patient might be in the hospital for one to two nights. They should not put weight on their fused ankle for six to 12 weeks after the surgery. Physiotherapists can teach well how to move around with a walker or crutches. They will work with the patient to ensure they move about independently before the discharge.
What Precautions Are to be Taken After the Surgery?
-
One should rest for some days.
-
The patient should avoid driving as the subtalar joint must be fully fused before driving.
-
Keep the legs elevated to control swelling.
-
After 10 to 14 days, the patient needs to come back to have the stitches removed. The patient might be given a lighter-weight cast.
-
Be sure to take pain medications as advised.
-
The surgeon might take regular X-rays to check for the extent of fusion. As the fusion strengthens, one might be allowed to put weight on one's foot. The patient is required to be in touch with a physiotherapist to identify better to start walking without a limp.
-
The patient should rest for at least 10 to 12 weeks for better recovery before returning to work and other activities.
-
Discuss with the surgeon regarding any return to work. It might take around a year to feel the full benefits of subtalar fusion.
-
Many patients make a good recovery from subtalar fusion surgery. They must ask their doctor about returning to sports or other rigorous activities with their surgeon.
What Are the Complications Associated With Subtalar Fusion?
Any surgical procedure can result in complications. Some of the complications associated with subtalar fusion are :
- Pain.
-
Bleeding.
-
Blood clots (DVT).
Specific complications of ankle fusion include nerve damage, numbness, nonunion (lack of fusion), and malunion (displaced healing).
Conclusion:
Subtalar fusion is a process performed to correct the deformities of the subtalar joint, which is situated in the ankle. It is incorporated to correct rigid, painful deformities or instability of the subtalar joint or, more frequently, to eliminate arthritis, which turns painful for this joint. Subtalar fusion is frequently done under general anesthesia. An experienced orthopedic surgeon performs this surgery by examining various aspects of an individual's health. The surgeon first makes an incision (cut) on the outer surface of the ankle. The damaged joint surfaces are cleaned properly and cleared, and the joints are fixed together using one or two screws by the back of the heel. Sometimes, people can return to everyday life after a few weeks or months. It can also have certain complications, unlike any other surgery, like pain, bleeding, malunion, nonunion of the bone, etc.
