The puborectalis muscle is a key part of the pelvic floor that helps control bowel movements by forming a sling around the rectum. When this muscle becomes weak, injured, or inflamed, it can lead to a variety of conditions that affect your daily life, including incontinence, pelvic pain, and difficulties with bowel movements. In this guide, we explain the details of puborectalis muscle diseases in simple language.
The puborectalis is part of the pelvic floor muscles. It forms a U-shaped sling around the junction of the rectum and the anus. This muscle helps maintain continence (preventing unwanted leakage of stool) by keeping the angle between the rectum and the anal canal tight. When it contracts, it helps “close” the passage, and when it relaxes, it allows for defecation.
These refer to any conditions that affect the puborectalis muscle. Problems may include spasms, inflammation, weakness, or dysfunction that lead to symptoms such as pelvic pain, constipation, or incontinence. Examples include puborectalis syndrome, pelvic floor dysfunction, and other related disorders.
Pathophysiology:
Structure
-
Anatomy:
The puborectalis muscle is part of the levator ani group and is located in the deep pelvis. It originates from the pubic bone and loops around the rectum, attaching again to the same area. This arrangement forms a muscular “sling” that is vital for bowel control. -
Appearance:
It is a robust, thin muscle that is not visible from the outside but plays a critical role in pelvic stability and function.
Blood Supply
- Arterial Supply:
The muscle is supplied by small branches from pelvic arteries such as the internal pudendal artery and other nearby vessels. Good blood flow is essential to supply oxygen and nutrients, support muscle contraction, and aid healing.
Nerve Supply
- Innervation:
Nerves from the pudendal nerve and other branches of the sacral plexus provide the signals that control the puborectalis muscle. These nerves also carry pain signals if the muscle is injured or inflamed.
Functions
- Maintaining Continence:
By forming a loop around the rectum, the puborectalis helps keep the rectum angled correctly, preventing accidental leakage. - Assisting in Defecation:
The muscle relaxes when you need to have a bowel movement, allowing the passage to open. - Supporting Pelvic Organs:
It contributes to overall pelvic floor strength and stability, supporting organs like the bladder, uterus (in women), and rectum. - Contributing to Posture:
As part of the pelvic floor, it also helps in maintaining proper alignment and posture.
Types of Puborectalis Muscle Diseases
While not every condition affecting the puborectalis muscle is classified under a single label, several distinct issues are recognized:
-
Puborectalis Syndrome:
A condition often characterized by chronic pelvic pain and difficulty in coordinating the muscle during bowel movements. -
Pelvic Floor Dysfunction:
A broader term that includes puborectalis issues along with other pelvic floor muscles, leading to symptoms such as incontinence or constipation. -
Muscle Spasms or Hypertonicity:
Excessive tightness or spasm in the puborectalis, which can cause pain and disrupt normal bowel function. -
Muscle Weakness or Hypotonicity:
When the muscle loses strength, it may not be able to maintain continence properly. -
Traumatic Injury or Strain:
Damage from childbirth, surgery, or direct injury can affect the muscle’s function. -
Post-surgical or Post-radiation Changes:
Treatments for other pelvic conditions may lead to scarring or altered function in the puborectalis. -
Neuromuscular Disorders:
Conditions such as multiple sclerosis or spinal cord injuries that affect nerve supply may impair the muscle. -
Inflammatory Conditions:
Inflammation due to infections or autoimmune processes that affect pelvic tissues. -
Pelvic Organ Prolapse-related Issues:
When other pelvic structures are displaced, it may alter the function of the puborectalis. -
Idiopathic Conditions:
Sometimes, the exact cause is not known, and the muscle may simply malfunction without a clear underlying reason.
