Magnetic resonance imaging confirmed a rupture of the semitendinosus tendon at its tibial insertion. Flexes stifle, draws limb medially and caudally when not weight bearing. It inserts at the medial tibial condyle. The semitendinosus is one of the three muscles in the hamstring muscle group. Insertion : It inserts on posterior surface of the medial tibial condyle. The muscle inserts via a long tendon overlying the semimembranosus muscle at the upper part of the medial surface of the tibia behind the insertion . (With the exception of the short head of the biceps femoris) The hamstring muscle group includes two inner, or medial, muscles. Background: The semitendinosus tendon graft with an intact tibial insertion has a sustainable blood supply and might be beneficial for graft maturation after anterior cruciate ligament reconstruction (ACLR); however, its potential advantages for graft tendon-bone healing is still unclear. Action: Extends and adducts hand at the wrist. Origin: Lower 2/3 of the lateral supracondylar ridge of the humerus. The tendon of insertion provides rise to the subsequent 3 growths: 70 of 95. Fast twitch muscle fibers undergo rapid contractions for a short time period. The insertion point here is just anterior to the insertion point of the gracilis and the semitendinosus muscle. Gait was improved to variable degrees in 8 of 14 horses when the semitendinosus muscle alone was affected and in 4 of 6 horses when both the semitendinosus and . Semitendinosus Action.

This report presents a case of a rare insertion of accessory band of the semitendinosus tendon (to the fascia of the soleus muscle and tibia). Answer. Its origin is the ischial tuberosity on the inferior pelvis and it has a complex distal insertion connected to Popliteus Muscle, to the Medial meniscus, to the Medial Collateral Ligament and to the Tibia . #semitendinosus_origin #hamstrings_muscle. Medially rotates the thigh at the hip joint and the leg at Actions: Flexion of the hip. When starting in a supinated position, it acts to pronate the hand as it flexes the elbow. Origin & Insertion The semitendinosus originates at the superior portion of the iscial tuberosity. Origin. Both muscles originate with a common tendon from an posteromedial impression on the superior part of ischial tuberosity. Semitendinosus tendon retraction, degenerative changes of the tendon, decrease muscle volume and oedema are appreciable on MRI in acute/subacute phase; atrophy of the muscle belly and some degree of fibrosis, arranged in a concentric onion-like fashion circumscribing the tendon on axial imaging, can be observed in chronic rupture [1, 4, 5]. In horses, the muscle is comprised of two heads; the bellies of which then reunite and run as a flat tendon to the medial side of the leg. You can see you've got the hamstring muscle here and the gracilis, so they insert just behind the insertion point of the sartorius muscle. Action: Extension of the hip and tarsal joints, flexion of the stifles joint in the free non-weight-bearing limb. Origin: Lateral epicondyle of humerus. Furthermore, maintenance of the distal insertion of the semitendinosus autograft provides a strong biologic point of fixation, which can be helpful when reconstructing the patellar tendon.

The semimembranosus muscle, so called from its membranous tendon of origin, is situated at the back and medial side of the thigh.It is wider, flatter, and deeper than the semitendinosus (with which it shares very close insertion and attachment points). The three hamstring muscles alone make up the classification of muscles known as the posterior compartment of the thigh. Daily uses: Turning a corkscrew. Insertion: Posterior aspect of the medial condyle of tibia, sending fibers into the fascia over popliteal ligament. The semitendinosus muscle originates from the inferomedial part of the ischial tuberosity via a tendon it shares with the biceps femoris muscle, and from an aponeurosis connecting the two muscles. It works better during single movements. It is so named due to its long tendon of insertion. the pes anserinus. Supination.

An extensive literature search yielded few relevant studies for this specific injury. The semitendinosus tendon inserts at the upper part of the medial surface of the tibia, behind the attachment of sartorius and infero-anterior to the attachment of gracilis. The semitendinosus is inserted into the upper part of the medial surface of the tibia. The muscle fibers then descend in the posterior thigh and around the middle of the thigh, they give way to a cord-like tendon. Those were the muscles of the anterior compartment of the thigh.
