Peritoneum

Peritoneum

The peritoneum is a vital membrane that lines the abdominal cavity and covers most of the organs within it. It plays a crucial role in protecting the organs, providing a smooth surface for their movement, and facilitating various physiological processes. Understanding the anatomy and function of the peritoneum is essential for comprehending the complexities of the abdominal region.
Anatomy of the Peritoneum
The peritoneum is divided into two layers: the parietal peritoneum and the visceral...

Blood and Nerve Supply to the Bones

Blood and Nerve Supply to the Bones

Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Pain

Pain

Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

Intestinal Obstruction II: Pathophysiology

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...

Appendicitis-I: Introduction

Appendicitis-I: Introduction

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...

Appendicitis

Appendicitis

Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...

Summary

A rare foot bone, the os intermetatarseum, can cause pain in athletes. Surgical removal effectively treated pain in two athletes, highlighting its importance in diagnosing midfoot pain.

Area of Science:

Orthopedic surgery
Sports medicine
Anatomy

Background:

The os intermetatarseum is an uncommon accessory ossicle.
It is typically located between the first and second metatarsal bones.

Observation:

Two cases of athletes presenting with painful os intermetatarseum are detailed.
This condition can cause significant dorsal midfoot pain in athletic individuals.

Findings:

Surgical excision of the os intermetatarseum provided pain relief in both reported cases.
Athletes experiencing dorsal midfoot pain may have an os intermetatarseum.

Implications:

Consider os intermetatarseum in the differential diagnosis of athletic foot pain.
