Rectus Sheath Dysfunction

Rectus sheath dysfunction refers to problems within the rectus sheath, a fibrous compartment that contains the rectus abdominis muscles. These muscles are essential for various bodily functions, including posture, movement, and breathing. When the rectus sheath is compromised, it can lead to pain and limited mobility.

Types of Rectus Sheath Dysfunction

  1. Rectus Sheath Hematoma: A collection of blood within the rectus sheath due to trauma or injury.
  2. Rectus Sheath Abscess: An infection that causes pus accumulation within the rectus sheath.
  3. Rectus Sheath Tear: A rupture or tear in the rectus sheath, often due to excessive strain or injury.
  4. Rectus Sheath Fibrosis: Thickening or scarring of the rectus sheath tissue.
  5. Rectus Sheath Tumor: A growth or tumor within the rectus sheath, which can be benign or malignant.
  6. Rectus Sheath Inflammation: Swelling and irritation within the rectus sheath.
  7. Rectus Sheath Diastasis: Separation of the rectus abdominis muscles, often seen in pregnancy.
  8. Rectus Sheath Weakness: Reduced strength and functionality of the rectus sheath.
  9. Rectus Sheath Strain: Overstretching or overuse of the rectus sheath.
  10. Rectus Sheath Calcification: Hardening of the rectus sheath due to calcium deposits.

Causes of Rectus Sheath Dysfunction

  1. Trauma or Injury: Blunt force trauma or sharp injuries can damage the rectus sheath.
