Tenosynovitis

Tenosynovitis refers to inflammation of the synovium, a protective sheath that covers your tendons and produces a fluid to help keep them lubricated. 

Tenosynovitis most commonly involves the tendons of the hands, wrists, or feet. Tenosynovitis inflammation is commonly caused by infection or repetitive use over time. Because of this, athletes, gamers, and those engaged in clerical occupations are at high risk. 

Common symptoms tend to be gradual, while those associated with infection can develop rapidly. Infectious tenosynovitis can be extremely tender to the touch with warmth and swelling. Pus or fluid draining from the surrounding skin and a high fever may also be present. 

Our specialists at Lancaster Orthopedic Associates of Lancaster are expertly trained to care for your tendons and their surrounding structures. Schedule an appointment for an orthopedic evaluation.

Causes

  • Occupations requiring repetitive motions such as clerical positions, carpenters, and factory workers
  • An impaired immune system that may make you more susceptible to infection
  • Conditions such as rheumatoid arthritis, diabetes, scleroderma, and gout, among others 

Diagnosis

  • Physical examination of the area
  • X-ray to evaluate bone condition 
  • MRI to evaluate muscle and soft tissue health
  • Aspiration of joint fluid may be performed for analysis and identification of bacteria

Treatment Options

  • RICE therapy: Rest, Ice, Compression, Elevation
  • Nonsteroidal, anti-inflammatory medications for pain relief
  • Physical therapy
  • Immobilization via brace, splinting, or tape
