Posterior oblique ligament origin and insertion

Ligaments of the Knee - Recon - Orthobullet

  1. originates from medial femoral epicondyle and inserts into periosteum of proximal tibia (deep to pes anserinus) the superficial portion of the MCL contributes 57% and 78% of medial stability at 5 degrees and 25 degrees of knee flexion, respectively. the superficial MCL is the primary stabilizer to valgus stress at all angle
  2. Most authors have described the origin of the ligament to be the adductor tubercle, but LaPrade et al (10) in their anatomic study found the origin to be distal and posterior to it. Wijdicks et al (15) also found the insertion point to be distal and posterior to the adductor tubercle
  3. Its proximal insertion or origin is next to the distal center of the intercollicular groove of the medial malleolus. The distal insertion is located on the posteroinferior medial talar body inferior to the insertion of the deep posterior tibiotalar ligament and anterior to the posteromedial talar tubercle 1
  4. The posterior cruciate ligament (PCL) is normally mildly concave in an anterior direction. With anterior cruciate ligament (ACL) tear and anterior subluxation of the tibia, the PCL may become buckled. This may be measured on a sagittal image through the mid PCL
  5. The oblique popliteal ligament crosses the back of the knee joint. A fibrous band of tissue, this ligament is both broad and flat in shape. It originates as an extension of the semimembranosus..
  6. Posterior fibers: originate from the posterior end of the iliac crest and the thoracolumbar fascia. The fibers then ascend superolaterally and insert into the inferior borders and tips of the lower three or four ribs and their cartilages. Here, these merge with the internal intercostals of the aforementioned ribs
  7. Structure. The oblique popliteal ligament originates from the adductor tubercle of the medial side of the femur. It is also attached to the upper margin of the intercondyloid fossa and posterior surface of the femur close to the articular margins of the condyles.It crosses the popliteal fossa from medial to lateral. It is attached below to the posterior margin of the head of the tibia

Annular ligament is a U shaped ligament that attaches to anterior and posterior portion of sigmoid notch (radial notch) of proximal ulna and encircles the radial head. Anterior insertion: taut in supination. Posterior insertion: taut in pronation.

A variety of musculoskeletal disorders can create marked hyperextension at the knee as the result of an imbalance of forces The Deep medial ligament (dMCL) is divided into two, the meniscofemoral and meniscotibial ligaments. The origin of the meniscofemoral comes from the femur just distal to the superficial medial collateral, inserting into the medial menisci. The meniscotibial ligament is thicker and shorter

including the deep MCL, posterior oblique ligament (POL), and semimembranosus, are the key components providing valgus stability to the knee. Medial-sided in-juries involving the superficial MCL constitute the most common ligamentous injury of the knee.1 The superfi-cial MCL femoral origin is located 3.2 mm proximal an The posterior oblique ligament (POL) is part of the posterior third of the joint capsule and is formed by the superficial, the tibial, and the capsular arms . The POL maintains medial stability and resists anteromedial tibial subluxation. but the ligament is still closely attached to the femoral and tibial bone at its origin and insertion.

This ligament is in relation with the triceps brachii and flexor carpi ulnaris and the ulnar nerve, and gives origin to part of the flexor digitorum superficialis The Posterior Abdominal Wall. The posterior abdominal wall is a complex region of anatomy. It is formed by the lumbar vertebrae, pelvic girdle, posterior abdominal muscles and their associated fascia. Major vessels, nerves and organs are located on the inner surface of the posterior abdominal wall The inferior rectus muscle is a narrow, strap-shaped muscle of the orbit that extends over the floor of the orbit. Alike most of the extraocular muscles, the inferior rectus muscle originates from the common tendinous ring, also called the annulus of Zinn, that is found in the posterior pole of the orbit encircling the margins of the optic canal ORIGIN Deep part (horizontal):supinator crest and fossa of ulna. Superficial part (downwards): lateral epicondyle and lateral ligament of elbow and annular ligament: INSERTION Neck and shaft of radius, between anterior and posterior oblique lines: ACTION Supinates forearm.

  6. The oblique popliteal ligament (OPL) is an integral component of the knee, reinforcing the joint capsule posteriorly. Originating posteromedially from the distal tendon of semimembranosus (SM), this thin, broad fascial band passes superolaterally and obliquely towards the posterolateral aspect of the lateral femoral condyle (LFC) [1-3].From a functional perspective, the OPL is suggested to.

Layer 2: SMCL and Posterior Oblique Ligament. The SMCL is a well-defined structure that spans the medial joint line from the femur to tibia. According to LaPrade and coworkers, 28 the SMCL does not attach directly to the medial epicondyle of the femur, but is centered in a depression 4.8 mm posterior and 3.2 mm proximal to the medial epicondyle center Appears as a single round ligament but consists of two major parts; rotates 90° from an antero-posterior alignment at femoral origin to medial-lateral insertion at posterior tibia Anterolateral bundle: Bulk of ligament, taut in flexion, lax in extension; Posteromedial (oblique) bundle: Taut in extension, lax in flexio As would be expected, the more pregnancies a woman has, the higher her chances of SI joint problems.

The oblique popliteal ligament (OPL) is the largest structure on the posterior aspect of the knee, and given its broad shape, it is probably vulnerable to, or easily involved in, posterior knee. - when the oblique popliteal ligament is pulled medially and forward, tightens the posterior capsule of the knee;br/> - this maneuver can be used to tighten the posterior capsule in the posteromedial corner of the knee in surgical repairbr/> Both the supraspinous ligament and the interspinous ligament are the first posterior ligaments to fail.

  1. Oblique popliteal ligament. The oblique popliteal ligament is a broad, flat band of connective tissue that crosses the back of the knee. It originates on the medial condyle of the tibia as an extension of the semimembranosus muscle's tendon and inserts on the lateral condyle of the femur

The posterior cruciate ligament (PCL) is a ligament within the knee.Ligaments are tough bands of tissue that connect bones. The PCL -- similar to the anterior cruciate ligament (ACL) -- connects. The internal oblique muscle is a diagonal muscle that is found at each side of the body, just lateral to the abdomen. This muscle has several different points of origin, which include: Iliac crest. The normal femoral origin of the posterior cruciate ligament is shown on this T1-weighted coronal image. Only a portion of the ligament is seen because of the normal oblique course of the ligament. The posterior cruciate ligament (black arrow) is of lower signal intensity than the anterior cruciate ligament (open arrow) The posterior oblique ligament assists the semimembranosus to dynamically stabilize the medial knee (21). Previous anatomical studies had described the s-MCL as having oblique posterior portions (23-25). It is now believed that these studies were, in fact, identifying the posterior oblique ligament and not variations of the s-MCL (18

Origin - Iliac crest. Inguinal ligament. Thoracolumbar fascia. Insertion - Lower 3-4 ribs. Linea alba. Actions - Contraction of one side alone laterally bends the trunk to that side and rotates the trunk to the other side. Compresses the abdomen and supports the abdominal viscera. Innervation - Ventral rami of thoracic nerves. The posterior oblique ligament, which is confluent with the posterior edge of the superficial medial collateral ligament, is reinforced by the semimembranosus and is critical to medial knee stability. If needed, the reconstruction can be augmented with a soft-tissue graft at the anatomic origin and insertion of the medial collateral.

Superior Oblique: (3 in the figure) The superior oblique is the longest and thinnest eye muscle. Origin - arises above and medial to the optic foramen by a narrow tendon which partially overlaps the origin of the levator. Insertion - inserted to trochlea at orbital rim, on the medial wall of the antero-superior-medial orbit on the frontal. The oblique inferior retinaculum comprises two bands, a superomedial and an inframedial which unite to form a single lateral attachment. The tibialis anterior tendon passes deep to the oblique inferomedial ligament just prior to its insertion into the medial cuneiform
