Deep Posterior Compartment Syndrome

What is deep posterior compartment syndrome?

The muscles of the lower leg are organised into several compartments, each enclosed by tough, inelastic connective tissue. The deep posterior compartment lies directly behind the shin bone (tibia) and beneath the large calf muscle (gastrocnemius). During exercise, blood flow to this area increases, causing the muscles to expand. If the surrounding compartment cannot stretch enough to accommodate this increased volume, internal pressure rises. This elevated pressure can restrict blood flow and compress the nerves and muscles within the compartment, resulting in pain and dysfunction.

Deep posterior compartment syndrome may be caused by several factors, including a rapid increase in muscle size and volume within the compartment, engaging in unfamiliar or intense physical activity, or the gradual tightening of the inelastic connective tissue surrounding the muscles. Physiotherapy is a highly effective treatment, helping to reduce symptoms, restore function, and prevent recurrence through targeted rehabilitation and activity modification.

What are the symptoms of deep posterior compartment syndrome?

Deep posterior compartment syndrome typically causes pain along the inner edge of the shin bone (tibia). This pain is often described as aching, tightness, cramping, or a squeezing sensation. It usually worsens during walking or exercise and only begins to ease once the activity stops. As the muscles reduce in volume post-exercise, pressure within the compartment returns to normal, and the pain gradually subsides. Other symptoms may include:

  • A sensation of heaviness or fatigue in the lower leg
  • Numbness or tingling in the sole of the foot or toes
  • Weakness in foot or toe movement
  • Swelling or tightness that increases with activity
  • Symptoms that worsen with repeated exertion

What should I do if I have deep posterior compartment syndrome?

Deep posterior compartment syndrome can become a persistent issue if not properly diagnosed and managed. If you suspect you may be experiencing this condition, it is important to schedule a physiotherapy appointment as soon as possible. In the meantime, you should avoid any activities that trigger your symptoms, as continued stress on the area may worsen the condition and delay recovery.

Physiotherapy treatment for deep posterior compartment syndrome.

Physiotherapy plays a key role in the treatment of deep posterior compartment syndrome. At your initial assessment, your physiotherapist will evaluate your symptoms, confirm the diagnosis, and determine the severity of the condition. Based on this assessment, a tailored treatment plan will be developed. Treatment may include:

  • Activity modification and rest advice
  • Manual therapy to reduce muscle tension
  • Stretching and mobility exercises
  • Strengthening to improve muscle balance and endurance
  • Gait and biomechanical analysis
  • Gradual return-to-activity planning

What shouldn’t I do if I have deep posterior compartment syndrome?

If you suspect you have deep posterior compartment syndrome, it is important not to push through the pain during exercise. Continuing activity can significantly worsen the condition by further increasing pressure within the compartment, potentially leading to more serious complications.

Could there be any long-term effects from deep posterior compartment syndrome?

Deep posterior compartment syndrome typically does not lead to long-term effects when it is accurately diagnosed and appropriately treated in a timely manner.
