What Causes Tenosynovitis?

Published in Tendon Inflammation Causes 2 mins read

Tenosynovitis can arise from both infective and non-infective causes, with non-infective cases further broken down into autoimmune, overuse, and idiopathic categories.

Understanding the Causes of Tenosynovitis

Tenosynovitis, essentially inflammation of the tendon sheath, has a variety of origins. It is important to distinguish between the two main types.

Infective Tenosynovitis

This type arises from bacterial, viral, or fungal infections that can cause inflammation of the tendon sheath. This form requires a different approach to treatment and is not covered in the included reference materials.

Non-Infective Tenosynovitis

According to the provided reference, non-infective tenosynovitis can be caused by several factors:

  • Autoimmune Conditions: Conditions such as rheumatoid arthritis or lupus can lead to inflammation that affects the tendon sheaths.

  • Overuse: Repetitive motions or overuse of particular joints can cause inflammation in the tendon sheaths. This is sometimes called repetitive strain injury or overuse syndrome.

    • Examples:
      • Typing on a keyboard for prolonged periods.
      • Assembly line work.
      • Activities involving repetitive movements, such as painting or gardening.
  • Idiopathic: In some cases, the cause of tenosynovitis is unknown (idiopathic), meaning it arises without a clear and identifiable reason.

Table Summarizing Causes of Tenosynovitis

Cause Category Subcategory Description
Infective Infections Caused by bacteria, viruses, or fungi that infect the tendon sheath.
Non-Infective Autoimmune Conditions Inflammation stemming from autoimmune diseases such as rheumatoid arthritis.
Overuse Repetitive motion or strain on specific joints leading to inflammation of the tendon sheath, often referred to as repetitive strain injury.
Idiopathic Tenosynovitis with an unknown cause.

Practical Insights and Solutions

Understanding the various causes is the first step in both prevention and treatment.

  • For Overuse-Related Cases: Taking regular breaks during repetitive activities and modifying work environments to be more ergonomic is important.
  • For Autoimmune Cases: Managing the underlying condition through prescribed medication is crucial, and this may alleviate symptoms of tenosynovitis.
  • For All Types: A proper diagnosis by a medical professional is necessary to determine the root cause and ensure effective treatment.
