What is a Gastroc Slide?

The gastroc slide is a surgical procedure performed to lengthen the most superficial layer of the calf muscles. The procedure is designed to improve range of motion through the ankle joint, and thereby decrease stress and pressure in the foot and the entire lower extremity. The procedure is performed through a small (1"-11/2") incision on the medial (inside) side of the mid-calf. A plastic surgery closure is utilized, and the scar is minimal.

Why do I need a Gastroc Slide?

Many patients with foot and ankle complaints have a tight calf muscle and can benefit from a gastroc slide. Studies have shown nearly a 30% decrease in stress through the foot and ankle following a gastroc slide. Patients with plantar fascitis, forefoot overload "neuroma pain", and Achilles tendonitis have had relief of symptoms 93-94% of the time following the gastroc slide. The gastroc slide can also benefit patients who have bunions, hammer toes, painful planus (flat) or cavus (high-arched) feet, ankle instability, neuropathy from diabetes or other causes. The gastroc slide may also be used to improve ankle flexibility and decrease stress in the foot and ankle for trauma patients-either acutely or in the case of post-traumatic arthritis.

What Can I Expect the Day of Surgery?

The Gastroc Slide is performed as an outpatient procedure. Typically the procedure performed under general anesthesia and lasts less than 15 minutes.

What Can I Expect Immediately Following Surgery?

Patients may bear weight immediately following surgery while wearing a post-operative boot. Most patients experience little to no discomfort. Some patients describe a mild to moderate soreness or cramping sensation which typically resolves in a few days. Prescription pain medication is used during that time. The post-operative boot and bandage remain dry and in place during the first two weeks following surgery. Bandages will be removed and the incision checked at the 2 week post-operative visit. Starting at 2 weeks patients may wear a regular shoe (running shoes are usually recommended) for walking, and will continue to wear the boot for sleep through the 4th week. During weeks 2-4, patients will gradually increase their level of low impact activities such as walking or cycling. Progress and relief of symptoms are monitored at a 6 week visit.

Long-Term Recovery

Time off from work depends on your occupation. Patients with sedentary jobs can usually return to work in 2-3 days, while patients with physically demanding jobs may require 4-6 weeks to return to work. Most patients experience some temporary weakness. Good function often returns in 6-8 weeks, but it may take 6 months or more for strength to return to 100%. Patients may drive as soon as they are able to walk without pain, and when they are off of pain medication. The gastroc slide does not add recovery time when done in conjunction with other procedures. Bilateral (both legs) gastroc slides can be performed to reduce recovery times, but this is generally reserved for younger, more athletic patients.

Is this a new procedure?

No. The original procedure was described in 1959 by Dr. Strayer. Since that time the procedure has evolved to minimize scarring and complications.

What are the Potential Complications?

Like any surgical procedure, there are risks from anesthesia, the possibility of infection, the possibility of swelling or blood clots, and the possibility of nerve injury, resulting in numbness. The overall chance of any one of these complications occurring is generally less than 1%.
