Postpartum symphysis pubis diastasis.
Radiology Case Reports
|June 17, 2016
Summary
Pubic symphysis widening during pregnancy, especially over 15mm (subluxation), can cause pain and deformity. While conservative treatment is common, surgical stabilization may be necessary in some cases.
Area of Science:
- Anatomy
- Orthopedics
- Physiology
Background:
- The pubic symphysis is a midline, nonsynovial joint connecting the superior pubic rami.
- It features a fibrocartilaginous disk reinforced by ligaments, allowing minimal movement (0.5-1mm).
Observation:
- Hormonal changes during pregnancy cause physiological widening of the pubic symphysis and sacroiliac joints.
- Diastasis exceeding 15mm is classified as subluxation, often presenting with pain and swelling.
Findings:
- Pregnancy-induced hormonal stimulation leads to pubic symphysis widening.
- Symphysis pubis diastasis greater than 15mm indicates subluxation, associated with pain and potential deformity.
Implications:
- Most cases of pubic symphysis diastasis are managed conservatively.
- Surgical intervention, including internal or external fixation, may be required for severe or persistent cases.

Pathophysiology of Diabetes
4.2K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Disorders of the Female Reproductive System
4.7K
The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...

Muscles of the Pelvic Floor and Perineum
5.6K
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

Appendicitis-I: Introduction
3.3K
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
605
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
