Puborectalis Muscle Strain

A puborectalis muscle strain occurs when the puborectalis muscle, which helps control the passage of stool, is injured. The injury may involve small tears or overstretching. This strain can cause pain, weakness, and sometimes problems with controlling bowel movements. It is often related to overexertion, sudden movements, or trauma such as during childbirth or heavy lifting.

Anatomy and Pathophysiology

Structure of the Puborectalis Muscle

• Location: The puborectalis muscle is part of the pelvic floor. It loops around the back of the rectum, forming a U-shaped sling.
• Relation to Other Muscles: It works closely with other pelvic floor muscles to support the pelvic organs, such as the bladder, uterus (in women), and rectum.
• Appearance: It is a thin, yet strong, muscle that helps maintain the angle between the rectum and the anal canal.

Blood Supply

• Arterial Supply: The puborectalis muscle receives blood from branches of the internal iliac arteries. Good blood flow is essential for the muscle to get oxygen and nutrients needed for repair and function.
• Importance: Adequate blood supply supports healing after a strain and helps maintain muscle strength.

Nerve Supply

• Nerves Involved: The muscle is innervated by branches of the pudendal nerve and other pelvic nerves. This nerve supply controls muscle contraction and helps in feeling pain when there is an injury.
• Role of Nerves: Proper nerve signals ensure that the muscle contracts correctly during bowel movements and other pelvic functions.

Functions

1. Maintaining Fecal Continence: It helps keep the rectum in the correct position to prevent accidental leakage.
2. Assisting in Defecation: The muscle relaxes and contracts as needed during bowel movements.
3. Pelvic Support: It contributes to the overall support of the pelvic organs.
4. Stabilizing the Pelvic Floor: Together with other muscles, it helps maintain balance and posture.

Types of Puborectalis Muscle Strain

Strains can vary in severity. They are generally categorized by the extent of muscle damage:

1. Mild Strain (Grade I)

   • Minor overstretching with minimal tearing.
   • Slight pain and discomfort.
   • Quick recovery with rest and self-care.

2. Moderate Strain (Grade II)

   • More extensive tearing of muscle fibers.
   • Noticeable pain, swelling, and difficulty with bowel control.
   • May require physical therapy and additional treatment.

3. Severe Strain (Grade III)

   • Significant tearing or rupture of the muscle.
   • Severe pain, bruising, and marked loss of function.
   • Often requires advanced medical intervention and a longer recovery time.

10. What non-drug treatments can I try?

Options include rest, ice or heat therapy, pelvic floor exercises, massage, and guided relaxation techniques.

11. Are there any risks of surgery for this injury?

Surgery is rarely needed and is usually considered only when other treatments fail or complications occur.

12. Can lifestyle changes prevent a puborectalis strain?

Yes, regular exercise, proper lifting techniques, maintaining a healthy weight, and avoiding straining during bowel movements can help prevent it.

13. How long does recovery typically take?

Recovery time varies from a few weeks for mild strains to several months for more severe injuries.

14. Are there any complications if the strain is left untreated?

Untreated strains may lead to chronic pain, incontinence, or further weakening of the pelvic floor muscles.

15. What should I do immediately after suspecting a strain?

Rest and use the RICE method (Rest, Ice, Compression, Elevation) and consult a healthcare provider if the pain persists or worsens.
