• #1 Ganglion Cyst: Practice Essentials, Anatomy, Pathophysiology

  https://emedicine.medscape.com/article/1243454-overview

  Although no definitive etiology has been established, the theory that the ganglion is the degeneration of the mucoid connective tissue, specifically collagen, has dominated since 1893, when Ledderhose described it as such. […] The etiology of the ganglion cyst has been described as an outpouching of synovium; as an irritation of articular tissue, creating a new formation; and, the most common and accepted theory, as a degeneration of connective tissue and cystic space formation. It has also been suggested that degeneration of the connective tissue is caused by an irritation or chronic damage causing the mesenchymal cells or fibroblasts to produce mucin.

  Ganglion cysts are synovial cysts that are filled with gelatinous mucoid material and commonly encountered in orthopedic clinical practice. Although the exact etiology of the development of ganglion cysts is unknown, they are believed to arise from repetitive microtrauma resulting in mucinous degeneration of connective tissue. […] Numerous theories have been presented in the past regarding the etiology of ganglion cysts with no present consensus. One theory introduced by Eller in 1746 is that ganglion cysts are the result of the herniation of synovial tissue from joints. Another theory postulated by Carp and Stout in 1926, which forms the basis of most modern belief, suggests that ganglion cysts result from mucinous degeneration of connective tissue secondary to chronic damage. Currently, most authors agree that ganglion cysts arise from mesenchymal cells at the synovial capsular junction as a result of the continuous micro-injury. Repetitive injury to the supporting capsular and ligamentous structures appears to stimulate fibroblasts to produce hyaluronic acid, which accumulates to produce the mucin „jelly-like” material commonly found in ganglion cysts.

• #1 Ganglion Cyst on Wrist – SportsMD

  https://www.sportsmd.com/sports-injuries/wrist-hand-injuries/ganglion-cyst-on-wrist/

  Ganglion cysts on wrist are benign soft tissue growths that usually appear at the wrist, but can occur at virtually any joint. […] Theories abound regarding how the ganglion cyst developed. Originally, they were thought to be simple herniations, or out-pouchings, of the lining of a joint, but as there is no synovial lining present within the cyst on microscopy, this is unlikely. […] They have also been postulated to be due to chronic inflammation, or irritation of the joint, but likewise there are none of the typical cellular inflammatory changes in a ganglion cyst, making this theory unlikely as well. […] Three of the most plausible theories on how ganglion cyst develop: 1) The capsular rent theory: A tear forms in the joint capsule, the fibrous coat of a joint sealing it off from outside tissue and keeping synovial fluid in the joint.

• #1 Why Do Ganglion Cysts Form? Causes and Risk Factors

  https://www.drmorwood.com/general/why-do-ganglion-cysts-form-understanding-the-causes-and-risk-factors/

  Ganglion cysts are soft, fluid-filled lumps that most commonly appear on the wrists, hands, or fingers. These cysts can vary in size, often growing larger with repetitive movement or activity. Although they are generally harmless, ganglion cysts can cause discomfort, particularly if they press on nearby nerves. In this article, Monterey plastic and reconstructive microsurgery specialist, Dr. David Morwood explores the main causes, risk factors, and lifestyle contributors to the formation of ganglion cysts. […] The exact cause of ganglion cysts is still not completely understood, but several factors are believed to contribute to their formation: […] Repetitive Hand Movements – Activities that involve repetitive motions of the hands or wrists, such as typing, knitting, or playing certain sports, can increase the likelihood of developing ganglion cysts. These repetitive actions put continuous pressure on the joints, which may lead to cyst formation.

The excessive stress on the tendons or joints can lead to the accumulation of joint fluid, which then gets trapped, forming a cyst. […] Previous Hand or Joint Injuries – If you’ve had a hand injury or trauma to a joint, you’re at a higher risk of developing a ganglion cyst. Injuries can weaken the joint capsule or tendon sheaths, making them more prone to cyst formation. This is why they are sometimes referred to as a “hand injury cyst.” […] Certain risk factors can increase the likelihood of developing ganglion cysts: […] Age and Gender – Ganglion cysts are more common in individuals aged 15 to 40, with a higher incidence in women. Hormonal or anatomical factors may play a role in this increased susceptibility.

  Ganglion cyst is not considered a heritable disease, but it is not clear if a genetic predisposition of underlying connective tissues can contribute to the frequency of occurrence or likelihood of forming a cyst. […] A ganglion cyst is due to trauma to and degeneration of connective tissue. The degeneration of the connective tissue is accompanied by leakage and an accumulation of fluid within the tendon sheath. In some cases, pre-existing articular joint diseases, or mucoid degeneration of articular connective tissues can facilitate the development of ganglion cysts. […] The cause of ganglion cyst is still unknown. However, different theories have been proposed to explain the etiology of the condition. One theory, capsular rent theory, suggests that the cyst develops from chronic or acute joint stress/trauma. This causes leakage and accumulation of synovial fluid around the joint. The reaction of the fluid with tissues of the joint results in the formation of the ganglion cyst. […] A second theory holds that trauma to the joint can cause the breakdown of adjacent connective tissues and results in fluid accumulation and formation of a ganglion cyst.
