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] The cause is unknown. [3] The underlying mechanism is believed to involve an outpouching of the synovial membrane. [4] Diagnosis is typically based on examination.
A tendon sheath is a layer of synovial membrane around a tendon. [1] It permits the tendon to stretch [2] and not adhere to the surrounding fascia. It contains a lubricating fluid (synovial fluid) that allows for smooth motions of the tendon during muscle contraction and joint movements. [3] It has two layers: synovial sheath; fibrous tendon sheath
The tendons are inserted in the following manner: each receives a fibrous expansion from the interossei and lumbricals, and then spreads out into a broad aponeurosis, which covers the dorsal surface of the first phalanx: this aponeurosis, at the articulation of the first with the second phalanx, divides into three slips — an intermediate ...
The muscle ends in a long tendon, which runs behind the lateral malleolus of the ankle in a groove that it shares with the tendon of the fibularis brevis; the groove is converted into a canal by the superior fibular retinaculum, and the tendons in it are contained in a common mucous sheath. [2] The tendon then extends forward at an angle across ...
The fibularis brevis (bottom-most label) is a muscle of the lower leg and aids in plantar flexion and eversion of the foot. The fibularis brevis arises from the lower two-thirds of the lateral, or outward, surface of the fibula (inward in relation to the fibularis longus) and from the connective tissue between it and the muscles on the front and back of the leg.
A synovial sheath is one of the two membranes of a tendon sheath which covers a tendon. The other membrane is the outer fibrous tendon sheath. [1] The tendon invaginates the synovial sheath from one side so that the tendon is suspended from the membrane by the mesotendon, through which the blood vessels reach the tendon, in places where the range of movement is extensive.
Tendinopathy is a type of tendon disorder that results in pain, swelling, and impaired function. [2] The pain is typically worse with movement. [2] It most commonly occurs around the shoulder (rotator cuff tendinitis, biceps tendinitis), elbow (tennis elbow, golfer's elbow), wrist, hip, knee (jumper's knee, popliteus tendinopathy), or ankle (Achilles tendinitis).
On the front of the ankle the sheath for the Tibialis anterior extends from the upper margin of the transverse crural ligament to the interval between the diverging limbs of the cruciate ligament; those for the Extensor digitorum longus and Extensor hallucis longus reach upward to just above the level of the tips of the malleoli, the former being the higher.
