The adductor magnus is a large triangular muscle, situated on the medial side of the thigh.. It consists of two parts. The portion which arises from the ischiopubic ramus (a small part of the inferior ramus of the pubis, and the inferior ramus of the ischium) is called the pubofemoral portion, adductor portion, or adductor minimus, and the portion arising from the tuberosity of the ischium is ...
The adductor magnus tendon attaches to the distal medial femoral condyle just posterior and proximal to the adductor tubercle. [2] It has a fascial expansion on the distal-medial aspect that attaches to the medial gastrocnemius tendon, capsular arm of the POL, and posteromedial joint capsule.
Embryologically and phylogenically, the ligament represents the distal portion of the tendon of adductor magnus muscle. In lower animals, adductor magnus inserts into the tibia. Because of this, the ligament occasionally contains muscle fibres. This is an atavistic variation.
adductor longus; adductor brevis; adductor magnus; The obturator externus muscle is sometimes considered part of this group, [1] [2] [3] and sometimes excluded. [4] (Spatially, it is in this location, but functionally, it is more similar to the other lateral rotator group muscles). The pectineus is sometimes included in this group, [1] [3] and ...
The pectineus is the only adductor muscle that is innervated by the femoral nerve. The other adductor muscles are innervated by the obturator nerve [1] with the exception of a small part of the adductor magnus which is innervated by the tibial nerve. [4]
Green is the medial compartment (gracilis and adductor magnus), blue is the posterior (semimembrosus to biceps c. brevis) and red is the anterior (vastus lateralis to sartorius). The fascial compartments of thigh are the three fascial compartments that divide and contain the thigh muscles .
An adductor hiatus is described as oval or bridging depending on the shape of the upper boundary. It can also be described as muscular or fibrous depending on whether the structure surrounding is the muscular part or the tendinous part of the adductor magnus muscle. For example, the top drawing on the right shows an oval fibrous type of ...
Cortical desmoid (also known as a tug lesion or periosteal desmoid) is an irregularity of the distal femoral cortex that is caused by repetitive stress at the attachment of the adductor magnus aponeurosis. It is commonly observed in adolescents and is usually asymptomatic. This lesion is benign and tends to be self-limiting.
