The Evans technique is a surgical procedure to treat the mechanical instability of the lateral ankle ligaments. [ 1 ] [ 2 ] In the Evans procedure, [ 3 ] the peroneus brevis muscle is separated from its musculotendinous compound and its proximal end is sutured to the peroneus longus .
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 Schilling tendon procedure is a temporary surgical procedure developed by the former Boston Red Sox team physician William Morgan, MD, to stabilize the peroneus brevis tendon so that it is prevented from anterior displacement during ankle eversion. [1] If the peroneal retinaculum is torn, the
Between it and the tibialis anterior are the upper portions of the anterior tibial vessels and deep peroneal nerve. The muscle passes under the superior and inferior extensor retinaculum of foot in company with the fibularis tertius , and divides into four slips, which run forward on the dorsum of the foot, and are inserted into the second and ...
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.
Surgical Technique: [3] Incision is made over border of lateral malleolus; peroneal tendon exploration would require a posterolateral longitudinal incision; Surgeons care for peroneal tendons, sural nerve and lesser saphenous vein (which might be ligated), and branches of the superficial peroneal nerve;
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
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.
