About Ultrasound-Guided Fasciotomy for Exertional Compartment Syndrome
In chronic exertional compartment syndrome, pressure inside a muscle compartment of the lower leg rises too high during exercise. This causes aching, tightness, and sometimes numbness or foot weakness that start at a predictable point in activity and ease with rest.
A fasciotomy cuts the tough fascia around the affected compartment so the muscles have more room to expand. Traditional surgery uses longer incisions. With ultrasound guidance, Dr. Gruner can see the fascia, nerves, and blood vessels and release the fascia through small incisions.
Before a fasciotomy, we confirm the diagnosis, usually with compartment pressure testing, and try conservative options such as changes to running form, footwear, and training load.
What happens during treatment
- 1.
The diagnosis is confirmed with your history, exam, and compartment pressure testing, and ultrasound is used to map the fascia and nearby nerves.
- 2.
The leg is numbed with local anesthetic at the planned incision sites.
- 3.
Through small incisions, the fascia is released along the length of the compartment under live ultrasound guidance.
- 4.
The incisions are closed, and a compression dressing is applied.
- 5.
You go home the same day with instructions for walking, wound care, and a gradual return to running.
Who may be a good candidate
- Runners and athletes with chronic exertional compartment syndrome confirmed by testing.
- People whose symptoms have not improved with changes to training, running form, and footwear.
- People who want to return to running or sport without symptoms.
- Patients who prefer smaller incisions than traditional open fasciotomy, when the anatomy allows.
Recovery
Walking usually begins right away. The leg is often sore and swollen for several days, and a compression wrap helps. Most people start easy cross-training within a couple of weeks and return to running gradually over several weeks, guided by a structured progression.
Risks and limits
Risks include soreness, bruising, bleeding or a collection of blood under the skin, infection, and injury to a nearby nerve that can cause numbness on the leg or foot, which ultrasound guidance helps avoid. Symptoms can persist or return in some people. A fasciotomy is not appropriate unless the diagnosis is confirmed, and sudden severe leg pain after an injury is a different emergency that needs immediate care.
What to expect at your visit
- 1.
We listen first
Your visit opens with a real conversation: how the problem started, what you have already tried, and the activity you want back.
- 2.
Exam and in-office ultrasound
A hands-on exam, then ultrasound at the exam table, often while you move, so your physician can see the tendon, joint, or nerve involved.
- 3.
A clear diagnosis and plan
You leave knowing what is wrong and what your options are, from strength-based rehab to procedures, and why we recommend each one.
- 4.
Treatment and follow-through
Most procedures happen here in the office. We coordinate with your physical therapist and check progress against the goals you set.
Questions about Fasciotomy (CECS)
- Do I need compartment pressure testing before a fasciotomy?
- In most cases, yes. Testing confirms the diagnosis and helps rule out other causes of exercise-related leg pain, such as stress fractures or nerve entrapment. We want to be confident before recommending a release.
- When can I run again after a fasciotomy?
- Return to running is gradual. Most people start with walking and cross-training and build up to running over several weeks. Your plan depends on how the leg heals and what ultrasound shows at follow-up.
- Can both legs be treated?
- Compartment syndrome often affects both legs. Dr. Gruner will discuss whether to treat both at once or one at a time, based on your symptoms and activity goals.
