Tendinous Arch Cysts

Tendinous arch cysts are fluid-filled sacs that develop along or near the supportive bands of tissue (the tendinous arches) that help our tendons work properly. Although these cysts are usually benign (non-cancerous), they can cause discomfort, pain, and interfere with movement if not managed properly.

A tendinous arch is a band of connective tissue that supports a group of tendons and helps maintain the structure of joints and muscles. A cyst in this area is essentially a small sac filled with a clear or gel-like fluid. These cysts can develop as a response to stress, injury, or inflammation in the tendon area. Although they are mostly harmless, they might cause pain, swelling, or reduced mobility depending on their size and location.

Pathophysiology of Tendinous Arch Cysts

Understanding the pathophysiology means looking at how the cyst forms and affects the body.

Structure

• Cyst Composition: Tendinous arch cysts are lined with a thin membrane. Inside, they are filled with a clear or slightly viscous fluid.
• Location: They typically develop near the tendinous arches found in areas like the foot, wrist, or elbow, where the tendons form supportive curves.
• Appearance: Often, the cyst feels like a small, soft lump under the skin.

Blood Supply

• Vascular Supply: The region of the tendinous arch usually has a small network of blood vessels that supply nutrients to the tendon and surrounding tissues.
• Impact on the Cyst: While the cyst itself does not have an extensive blood supply, nearby small blood vessels help maintain the tissue health and may contribute to inflammation.

Nerve Supply

• Nerve Endings: The area around the tendinous arch has many nerve endings. These nerves can transmit pain signals when the cyst causes pressure or irritation.
• Symptom Development: When a cyst grows or becomes inflamed, these nerves can lead to pain, tingling, or a sensation of numbness in the affected region.

Functions and Effects

• Support Role: The tendinous arch helps in distributing force and stabilizing joints.
• Effect of Cyst Formation: When a cyst develops, it may:
  • Disrupt normal tendon movement.
  • Cause discomfort or pain during motion.
  • Lead to stiffness or reduced range of motion.
  • Sometimes affect nearby nerves, causing tingling or numbness.

Types of Tendinous Arch Cysts

While the term “tendinous arch cyst” generally refers to cysts that form in the tendon support area, there are a few variations or similar types that may be considered:

• Ganglion Cysts: These are the most common type and can form near joints and tendons, including the tendinous arch.
• Myxoid Cysts: Typically found near the fingers, they can also be seen around tendon areas.
• Synovial Cysts: These cysts develop from the synovial lining of a joint and may extend into nearby tendon regions.

The type of cyst is often determined by its location, appearance on imaging tests, and sometimes through a biopsy.

Causes of Tendinous Arch Cysts

There are many potential causes for tendinous arch cysts. Below is a list of 20 possible causes explained in simple terms:

1. Repetitive Overuse: Continuous, repeated stress on tendons can lead to cyst formation.
2. Minor Injuries: Small, repeated injuries to the tendon area may trigger a cyst.
3. Trauma: A single, significant injury or impact can damage the tendinous arch.
4. Tendinitis: Inflammation of the tendon can encourage cyst development.
5. Degenerative Changes: Natural wear and tear, especially with aging, can result in cyst formation.
6. Arthritis: Joint inflammation may spread to the tendon areas.
7. Inflammatory Conditions: Diseases like rheumatoid arthritis can affect tendon health.
8. Infection: In rare cases, infections in the tendon sheath can lead to a cyst.
9. Autoimmune Disorders: Conditions where the immune system attacks healthy tissue can cause inflammation and cyst formation.
10. Gout: Crystal deposits from gout can irritate tendons.
11. Pseudogout: Similar to gout, this condition can also lead to inflammation.
12. Abnormal Biomechanics: Poor movement patterns or joint alignment may stress the tendon.
13. Poor Foot Posture: Misaligned feet can put extra pressure on tendon arches.
14. Obesity: Excess weight increases stress on the tendons.
15. Improper Footwear: Shoes that lack proper support can strain the tendinous arch.
16. Metabolic Disorders: Conditions like diabetes can affect tendon health.
17. Local Tissue Degeneration: The gradual breakdown of tissue in the tendon area.
18. Repetitive Minor Strains: Continuous small strains over time.
19. Calcific Tendonitis: Calcium deposits within the tendon may lead to cyst formation.
20. Sudden Overstretching: An abrupt strain or stretch that exceeds the tendon’s capacity.
