Tendon sheaths

Bursitis is an inflammation of the bursa, the fluid-filled sac near the joint where the tendons and muscles pass over the bone. The bursa assists with movement by reducing friction between joints. Tendonitis (also known as tendinitis) is an inflammation of the tendon or, more specifically, the fibrous sheath that attaches muscle to bone.3 Tenosynovitis is an inflammation of the tendon sheath. 

Miscellaneous (tendinitis, epicondylitis, ganglion) In tendinitis or tenosynovitis, inject into the tendon sheath rather than into the substance of the tendon. In epicondylitis, outline the area of greatest tenderness and infiltrate the drug into the area.

Fibroma of tendon sheath and collagenous fibroma (desmoplastic fibroblastoma) are usually sufficiently distinct clinically and histologically to separate them from fibromatosis. They often react either diffusely or focally for muscle-specific actin and smooth muscle actin and may even show faint S-100 positivity.Desmin, however, is not found. In addition to sharing an immunophenotypic profile, fibroma of tendon sheath and collagenous fibroma have been observed to harbor the same abnormality of chromosome...

Another example of occupational problems associated with veterinary medicines is that of self-injection of oil-based vaccines (72). This can give rise to vascular compression, ischaemia and tissue damage, particularly if injection into the tendon sheath occurs (74). In the United Kingdom, this has resulted in advice being provided to hospital emergency departments so that prompt and appropriate surgical treatment can be given (75).

DeQuervain s disease A special case of tendosynovitis (sweUing and irritation of the tendon sheath) which occurs in the abductor and extensor tendons of the thumb, where they share a common sheath.

Repeated flexing of the wrist can injure the tendons, tendon sheaths, muscles, ligaments, joints and nerves of the hand and forearm. These repetitive strain injuries commonly occur in occupations involving repeated hand-wrist deviations (e.g., keyboard and computer operators), and frequently involve nerve compression at the wrist (e.g., carpal tunnel syndrome) (Chemiack, 1999). 

Inflammation of the tendon sheath of the thumb attributed to excessive friction between two thumb tendons and their common sheath. Usually caused by twisting and forceful gripping motions with the hands and is considered an ergonomic hazard. Deadman Switch... 

De Quervain s disease—The tendon sheath of both the long and short abductor muscles of the thumb narrows. 

Figure 13-1. Pictorial representation of the anatomy related to carpal tunnel syndrome. Nerves both left and right views), blood vessels (right view), tendons and tendon sheaths (right view) pass through the carpal region of the wrist. The large ligament over the carpal region helps keep tissues in place during wrist articulation. V arious forms of inflammation and disorders in the wrist and hands can result from repetitive motions.

Dequervain s Disease This disorder results from narrowing of the tendon sheath for both long and short abductor muscles of the thumb. This disease results from manual tasks involving radial or inward hand motions and firm grips. 

Tenosynovitis, Stenosing Tenosynovitis, or Tenova-ginitis These terms refer to inflammation involving the compression or narrowing of a tendon sheath. 

Type 1 tendons are long and cross at least one joint before they attach. They may course over and around bony structures and at these locations are invariably covered by a synovial sheath comprised of visceral and parietal layers. The visceral layer is intimately attached to the tendon surface and moves with the tendon. The parietal layer is a lax covering that blends with the visceral layer at the periphery of the tendon sheath to become the mesotendon, which contains the tendon vessels. The synovial sheath has the function of decreasing the friction between the tendon and the adjacent structures allowing smooth excursion of the tendon. A small amount of fluid may be present within the tendon sheath. Certain tendon sheaths may communicate with adjacent joints, in which case excess joint fluid may result in distension of the tendon sheath. A good example of this is the flexor hallucis longus tendon, which often communicates with the tibiotalar joint...
