Tendon sheaths are mesenchymal in cell origin and composed of two layers, an outer fibrous layer and an inner synovial layer. The fibrous layer Infectious tenosynovitis provides strength and vascularity to Dr. Alicia L. Bertone said that the sheath.

Fibrosis and adhesions can be minimized with passive range of motion exercises, intrathecal hyaluronate, and phenylbutazone therapy. Restrictive fibrosis may be treated successfully by annular ligament resection.

Light therapy Dr. Mary Dyson said that light has been used therapeutically for many centuries. Currently it is often applied in laser form. LASER is the acronym for Light Ampliifcation by the Stimulated Emission of Radiation. High-power medical lasers are used primarily to destroy cancerous tissue; in contrast, low-power lasers activate tissue components and in doing so
