Pubic Symphysis Diastasis

Anatomy? and Pathophysiology of Pubic Symphysis

The pubic symphysis disc is made of fibrous cartilage, in which apart from regularly arranged, thick, type I collagen fibers, chondrocytes are deployed. An additional feature of this tissue is the low content of glycosaminoglycans (2% dry weight). The arrangement of collagen fibers reflects the forces acting on the disc. Unlike the vitreous cartilage, the interpubic disc does not have perichondrium. The width of the pubic symphysis changes with age. In a newborn, it is 9–10 mm, gradually decreasing with age. A normal width of the pubic symphysis in adults is 3–6 mm, and is larger in the anterior part than the posterior [7].

Shear forces act on the joint while bending, standing, and while standing with the leg raised, known as tensile and frictional (sliding) forces, which have different values and vectors. While walking, pubic symphysis absorbs shock? from the pelvic ring. Under physiological conditions, the pubic symphysis may become loose in the range of 1–2 mm (during lower limb abduction) and may also be rotated by 1°.

During pregnancy, especially in the first trimester and during childbirth, relaxation of the structures of the pubic symphysis can be observed as a result of hormone activity [2,4,8]. The perinatal dilation of the symphysis by 3–5 mm is physiological, and returns to its original size within 5 months [7]. With soft tissue relaxation comes: anterior pelvic tilt, accentuated low-back curvature, hyperextension of the upper back, forward tilting of the neck, and backward extension of the neck [8].

Pubic symphysis diastasis is a medical condition where the pubic symphysis, the joint that connects the left and right sides of your pelvis, becomes too wide. This can happen due to trauma?, pregnancy, or other factors. When the joint separates, it can lead to pain, difficulty moving, and in some cases, long-term discomfort.

This condition is common in pregnancy but can also occur after accidents, injuries, or even during heavy lifting.

Pathophysiology (Structure, Blood, Nerve Supply)

The pubic symphysis is a cartilage joint located at the front of the pelvis. It’s normally held together by ligaments and supports weight during walking, running, and other activities. The blood supply to this joint comes from the obturator and external iliac arteries?. The nerve supply is primarily from the pelvic splanchnic nerves, which help control sensation and movement in the pelvis.

Types of Pubic Symphysis Diastasis

There are two main types:

1. Traumatic Diastasis: Caused by external forces such as an accident or heavy lifting.
2. Obstetric Diastasis: Common in women during or after childbirth, particularly when there is excess pressure on the pelvis.

 Causes of Pubic Symphysis Diastasis

1. Pregnancy: Increased pressure on the pelvis during labor? and delivery.
2. Childbirth: The passage of the baby can strain? the joint.
3. Car accidents: Sudden trauma can cause the joint to separate.
4. Heavy lifting: Overexerting the body can stretch or injure the pubic symphysis.
5. Fall or direct impact to the pelvis: Injuries can damage the joint.
6. Obesity: Extra weight can strain the pelvic joint.
7. Sacroiliac joint instability: Poor alignment of other pelvic joints.
8. Pelvic fractures: Broken bones in the pelvis can affect the pubic symphysis.
9. Pelvic inflammatory disease: Infections can lead to joint dysfunction.
10. Spinal misalignment: Poor posture or spinal issues affecting pelvic alignment.
11. Chronic? stress: Constant strain on the pelvis can lead to joint separation.
12. Overuse of pelvic muscles: Excessive physical activity without proper recovery.
13. Hormonal changes: In pregnancy, hormones like relaxin soften ligaments, which can lead to diastasis.
14. Multiple pregnancies: Having more than one pregnancy can increase risk.
15. Poor posture: Misalignment of the pelvis due to poor posture.
16. Age: Older adults may be more prone to joint issues.
17. Genetics: Some people may have a predisposition to pelvic instability.
18. Sedentary lifestyle: Weak muscles around the pelvis may lead to instability.
19. Muscle imbalance: Uneven strength in pelvic muscles can cause strain.
20. Previous pelvic surgery: Scar tissue or weakened joints can result from prior surgeries.
