A synovial structure surrounding the superficial and deep digital flexor tendons from the distal metacarpus/metatarsus to the pastern region, facilitating tendon gliding and efficient limb function. Disorders of the sheath include tenosynovitis, deep digital flexor tendon lesions, manica flexoria tears, and annular ligament constriction.
Digital Flexor Tendon Sheath
-
Superficial Digital Flexor Injury
Commonly known as bowed tendon, involving fiber disruption and inflammation. Management includes rest, biologics, and surgical intervention in select cases.
-
Complex Tenosynovitis
Chronic inflammation of the tendon sheath, often associated with adhesions or structural damage. Tenoscopic evaluation and lavage are commonly performed.
-
Annular Ligament Constriction
Fibrous thickening that restricts tendon gliding, leading to pain and swelling. Surgical release improves tendon movement.
-
Septic Tenosynovitis of the Digital Flexor Tendon Sheath
Infection within the tendon sheath requiring urgent lavage and antimicrobial therapy.
