Compartment Syndrome

[rank_math_breadcrumb]

Compartment syndrome occurs when increased pressure within a muscle compartment causes reduced blood flow to the affected area, potentially leading to muscle and nerve damage.

What is Compartment Syndrome?

Compartment syndrome is a medical condition that occurs when there is increased pressure within a muscle compartment. This pressure can cause compression of the blood vessels and nerves within that compartment, leading to muscle and nerve damage if left untreated. There are two main types of compartment syndrome: acute compartment syndrome and chronic exertional compartment syndrome.

Acute Compartment Syndrome

Acute compartment syndrome is a medical emergency that occurs as a result of a traumatic injury, such as a crush injury or fracture. This type of compartment syndrome can cause rapid onset of symptoms and requires immediate medical attention. The underlying cause of acute compartment syndrome is typically bleeding or swelling within the affected compartment, leading to increased pressure.

Chronic Exertional Compartment Syndrome

Chronic exertional compartment syndrome is a condition that occurs as a result of exercise or activity. This type of compartment syndrome typically affects the lower leg muscles, causing pain and discomfort during and after exercise. The underlying cause of chronic exertional compartment syndrome is thought to be related to increased muscle pressure during exercise, leading to decreased blood flow and oxygen to the affected muscles. Chronic exertional compartment syndrome can lead to muscle and nerve damage over time if left untreated.

Symptoms of Compartment Syndrome

Compartment syndrome can cause a wide range of symptoms, which can vary in severity depending on the underlying cause and how quickly the condition is diagnosed. Some of the most common symptoms to look out for include:

  • Pain that may feel severe and out of proportion to the injury or activity
  • Swelling or tightness in the affected muscle compartment
  • Tenderness or bruising over the affected area
  • Weakness or numbness in the affected limb
  • Difficulty moving the affected limb

In addition to these symptoms, acute compartment syndrome can cause neurological deficits, which can be a sign of severe muscle and nerve damage. In some cases, the lack of blood flow to the affected muscles may also cause ischemia, which can lead to tissue death if left untreated.

Another important symptom to be aware of is myoglobinuria, which is the presence of myoglobin (a protein released from damaged muscle tissue) in the urine. This condition can cause kidney damage if left untreated, so it’s important to monitor patients with compartment syndrome for this symptom.

Is it a Medical Emergency?

Because compartment syndrome can cause severe muscle and nerve damage, it’s important to seek medical attention right away if you experience any of the symptoms listed above. If left untreated, compartment syndrome can lead to permanent disability or even amputation in severe cases.

If you suspect that you or someone else may have compartment syndrome, it’s important to go to the emergency department immediately for evaluation and treatment.

Causes of Compartment Syndrome

Compartment syndrome occurs when pressure builds up within the muscle compartments, affecting blood flow and potentially leading to muscle and nerve damage. There are several underlying causes of compartment syndrome.

1. Traumatic Injury

Compartment syndrome can occur due to a traumatic injury, such as a crush injury or fracture. The increased pressure within the muscle compartment can cause muscle and nerve damage, leading to severe pain and weakness in the affected area.

2. Medical Conditions

Medical conditions can also lead to compartment syndrome. Deep vein thrombosis, a blood clot in a deep vein, can cause increased pressure in the affected limb, leading to compartment syndrome. Musculoskeletal disorders, such as chronic arthritis or tendonitis, can also cause increased pressure within muscle compartments.

3. Prolonged Immobility

Long periods of immobility, such as during a coma or sedation, can also cause compartment syndrome. Immobility can cause muscle swelling and increased pressure within the muscle compartments, leading to compartment syndrome.

4. Overuse Injuries

Overuse injuries, such as those caused by repetitive motions, can lead to exercise-induced compartment syndrome. This occurs when the increased pressure within the muscle compartment causes pain and weakness in the affected area during exercise.

It’s important to identify the underlying cause of compartment syndrome in order to properly treat and prevent it from occurring in the future. If you suspect you may have compartment syndrome, speak to your healthcare provider for proper diagnosis and treatment options.

Diagnosing and Treating Compartment Syndrome

Diagnosing compartment syndrome typically involves a physical exam and medical imaging tests such as magnetic resonance imaging (MRI) or computed tomography (CT) scans. These tests can help physicians determine the degree of pressure within the muscle compartments and the extent of potential muscle and nerve damage.

Treatment options for compartment syndrome depend on the severity of the condition. In acute cases, surgery is often required to relieve pressure. The most common surgical procedure for compartment syndrome is called a fasciotomy, which involves incisions in the affected muscle compartments to relieve pressure and improve blood flow. Post-surgery, physical therapy and rehabilitation exercises are typically prescribed to help restore muscle strength and function.

Non-surgical treatment options such as anti-inflammatory medications and physical therapy exercises may be prescribed in less severe cases. Anti-inflammatory medications such as ibuprofen can help reduce swelling and relieve pain, while physical therapy exercises can help improve muscle function and reduce the risk of long-term complications.

What is a Fasciotomy?

A fasciotomy is a surgical procedure that involves creating incisions in the affected muscle compartments to relieve pressure. During the procedure, a surgeon will carefully cut through the fascia tissue surrounding the affected muscle compartments, releasing excess pressure and fluid. The incisions are then closed using sutures or staples, depending on the extent of the incisions made.

Non-Surgical Treatment Options

In cases where surgery is not required, treatment may involve anti-inflammatory medications to reduce swelling and pain and physical therapy exercises to improve muscle function. Physical therapy may include myofascial release, a technique that involves applying pressure to the affected muscles to help release tension and improve blood flow. Additionally, orthotic devices such as braces or compression stockings may be prescribed to help reduce pressure within the muscle compartments during physical activity.

Rehabilitation Exercises

Physical therapy and rehabilitation exercises play a critical role in the recovery process for patients with compartment syndrome. These exercises are typically designed to help improve muscle strength and function, reduce pain and swelling, and prevent future complications. Rehabilitation exercises may include range-of-motion exercises, strength training, stretching, and aerobic conditioning. Patients may also benefit from working with a physical therapist who can personalize an exercise program to meet their individual needs and abilities.

Preventing Compartment Syndrome

While it’s not always possible to prevent every case of compartment syndrome, there are steps you can take to reduce your risk. Here are some tips to help you avoid this condition:

  • Wear appropriate protective gear during high-risk activities, such as sports or manual labour.
  • Gradually increase the intensity and duration of exercise to prevent sudden muscle swelling.
  • Use proper biomechanics during exercise to avoid excessive stress on muscles and joints.
  • If you have a history of exercise-induced compartment syndrome, speak to your doctor about using orthotics or modifying your activity to reduce your risk.
  • Seek prompt medical attention for any injury that may cause muscle swelling or compression.

Post-Treatment Management for Compartment Syndrome

After treatment for compartment syndrome, it is important to properly manage pain and rehabilitate the affected limb to prevent long-term muscle and nerve damage. Here are some strategies for post-treatment management:

Pain Management

While recovering from compartment syndrome, patients may experience ongoing pain and discomfort. Doctors may prescribe pain medication to manage these symptoms. It is important to take these medications as directed and to communicate with healthcare professionals about any concerns or side effects.

Myofascial Release

Myofascial release is a technique used by physical therapists to improve muscle function and reduce pain. This is done by applying gentle pressure to the affected area to release tension and improve blood flow. This technique can be helpful for patients recovering from compartment syndrome.

Rehabilitation Exercises

Physical therapy exercises can help strengthen muscles and improve range of motion in the affected limb. These exercises should be performed under the guidance of a healthcare professional and tailored to the patient’s individual needs.

Volkmann’s Contracture

Compartment syndrome can lead to a serious complication called Volkmann’s contracture, which occurs when muscle and nerve damage cause the fingers or wrist to become permanently bent. To prevent this, attending all follow-up appointments with healthcare professionals and continuing rehabilitation exercises as directed is important.

Post-treatment management for compartment syndrome involves proper pain management, myofascial release to improve muscle function, and rehabilitation exercises to prevent long-term complications such as Volkmann’s contracture.
