A ganglion cyst is a fluid-filled bump associated with a joint or tendon sheath. [3] It most often occurs at the back of the wrist , followed by the front of the wrist. [ 3 ] [ 4 ]
[5] [5]: 361 Localized/nodular TGCT (L-TGCT), sometimes referred to as “giant cell tumor of the tendon sheath”; [3]: 100 is a common tumor that presents as a slow-growing, encapsulated, localized and limited bump, most frequently in the fingers.
Ulnar tunnel syndrome is usually caused by a ganglion cyst pressing on the ulnar nerve, other causes include traumas to the wrist and repetitive movements, but often the cause is unknown (idiopathic). [2] Long distance bicycle rides are associated with transient alterations in ulnar nerve function. [3]
It could have up to four tendons with a single tendon inserting to the index or the middle finger being the two most common variations. [7] At the insertion the tendon of the extensor digitorum brevis manus often joins the extensor indicis proprius , [ 3 ] although it also occurs when the extensor indicis proprius is absent.
If the ganglion cyst is not bothersome, it should be left alone. Just removing the fluid from the cyst is not curative because fluid will come back in less than a week. Surgery is often done for large cysts but the results are poor. Recurrences are common, and there is always the possibility of nerve or joint damage. Inflamed tendons of the hand.
Ganglion cyst is associated with minimal and specific pain, such as with forceful hyperextension (push up maneuver) or a dorsal wrist ganglion (fluid-filled closed sac with a joint or tendon sheath in the wrist) Kienbock's disease (breakdown of the lunate bone) Tendinopathy in the wrist (extensor) or thumb (De Quervain syndrome) Inflammatory ...

Triggering is predictably resolved by a relatively simple surgical procedure under local anesthesia. The surgeon will cut the sheath that is restricting the tendon. The patient should be awake in order to confirm adequate release. On occasion, triggering does not resolve until a slip of the FDS (flexor digitorum superficialis) tendon is resected.
