The posterior oblique ligament (POL) is the predominant ligamentous structure on the posterior medial corner of the knee joint. A thorough understanding of the anatomy, biomechanics, diagnosis, treatment and rehabilitation of POL injuries will aid orthopaedic surgeons in the management of these injuries The posterior oblique ligament (POL) is the predominant ligamentous structure on the posterior medial corner of the knee joint. The POL is located at the posterior one third of the medial capsular ligament, attaching proximally to the adductor tubercle of the femur and distally to the tibia and posterior aspect of the joint capsule Effect of sectioning the posterior cruciate ligament and posterolateral structures. The importance of the posterior oblique ligament in repairs of acute tears of the medial ligaments in knees with and without an associated rupture of the anterior cruciate ligament. Results of long-term follow-up. The Posteromedial Corner of the Knee

The oblique popliteal ligament (OPL) is a large ligamentous structure of the posterior knee and one of the five components of the posteromedial corner (PMC). It mainly prevents hyperextension in the knee 1-3 and in addition it is thought to prevent excessive external rotation 1 The PMC has five major components: the semimembranosus tendon and its expansions, the oblique popliteal ligament (OPL), the posterior oblique ligament (POL), the posteromedial joint capsule (or simply the posteromedial capsule), and the posterior horn of the medial meniscus

oblique popliteal ligament (OPL), the posterior oblique ligament (POL), the posteromedial joint capsule (or simply the posteromedial capsule), and the posterior horn of the medial meniscus variable meniscofemoral ligaments originate from the posterior horn of the lateral meniscus and insert into the substance of the PCL The posterior oblique ligament (POL) is found between the superficial medial collateral ligament (SMCL) and the semimembranosus tendon on this view. The medial head of the gastrocnemius muscle (MG), sartorius muscle (SA), gracilis tendon (G) and semitendinosus tendon (ST) are also indicated The dorsal deltoid ligament consists of three ligaments that are, from radial to ulnar, the dorsoradial ligament (DRL), the dorsal central ligament (DCL) and the posterior oblique ligament (POL). 4 Each originates from the dorsal tubercle of the trapezium and, together, they form a broad insertion on the dorsal edge of the first metacarpal base The oto-mandibular ligaments are the discomalleolar ligament (DML), which arises from the malleus (one of the ossicles of the middle ear) and runs to the medial retrodiscal tissue of the TMJ, and the anterior malleolar ligament (AML), which arises from the malleus and connects with the lingula of the mandible via the sphenomandibular ligament.The oto-mandibular ligaments may be implicated in.

nents were a lateral expansion to the oblique popliteal ligament; a direct arm, which attached to the tibia; and an an-terior arm. The oblique popliteal ligament, the largest posterior knee structure, formed a broad fascial sheath over the posterior aspect of the knee and measured 48.0 mm in length and 9.5 mm wide at its medial origin and 16. Anterior and posterior oblique ligaments, that originate from the anterior and posterior surfaces of trapezium, respectively. They both take an oblique medial course and attach to the medial side of the first metacarpal bone The medial ligament complex of the knee is composed of the superficial medial collateral ligament (sMCL), deep medial collateral ligament (dMCL), and the posterior oblique ligament (POL)

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 The oblique popliteal ligamen t (posterior ligament) is a broad, flat, fibrous band, formed of fasciculi separated from one another by apertures for the passage of vessels and nerves The posterior oblique portion of the MCL (posterior oblique ligament) is fused with layer III and closely attached to the medial meniscus and also the tibia (Fig. 5.4). Fig. 5.4 Superficial layer of the medial collateral ligament (MCL) and posterior oblique ligament (obl) . ­There is a split (S) anterior to the superficial layer of the MCL.

  2. 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.
  3. Posterior oblique ligament: This ligament protects against inward knee movement, particularly when the joint is fully extended. The POL also helps prevent excessive posterior sliding of the tibia on the femur. Oblique popliteal ligament: This ligament stabilizes against excessive external rotation of the tibia and hyperextension of the knee

Introduction. The posterior longitudinal ligament is one of the three more important ligaments that contribute to stability in the spine. It runs along the posterior aspect of the vertebral body inside the vertebral canal from the body of the axis to the sacrum. The ligament is composed of longitudinal fibers that are denser than the anterior longitudinal ligament Posterior capsule/oblique popliteal ligament (Top) Graphic at the level of cruciate ligaments is shown. The capsule, strengthened by the oblique popliteal ligament, extends from the posterior margin of femoral condyles to the intercondylar fossa at the tibia The spring ligament complex includes three ligaments: the superomedial calcaneonavicular ligament, the medioplantar oblique calcaneonavicular ligament, and the inferoplantar longitudinal calcaneonavicular ligament. Normal MR imaging anatomy of the spring ligament complex and the PTT are described and illustrated in detail

With regard to the literature regarding the oblique popliteal ligament, Woodburne's Essentials of Human Anatomystates that it is formed from the fibers of the distal semimembranosus tendon. All other anatomical texts and atlases that consider or depict the OPL state that the distal semimembranosus tendon contributes fibers to the OPL [2-20] Electronic address: goro.t@triton.ocn.ne.jp. (3)Department of Anatomy, Iwate Medical University, Morioka, Japan. PURPOSE: To describe the insertions of the superficial medial collateral ligament (sMCL) and posterior oblique ligament (POL) and their related osseous landmarks Purpose: To define the bony attachments of the medial ligaments relative to anatomical and radiographic bony landmarks, providing information for medial collateral ligament (MCL) surgery. Method: The femoral and tibial attachments of the superficial MCL (sMCL), deep MCL (dMCL) and posterior oblique ligament (POL), plus the medial epicondyle (ME) were defined by radiopaque staples in 22 knees The posterior cruciate ligament is located in the backside of the knee joint. Like the Anterior cruciate ligament (ACL), the PCL is intracapsular but 'extra synovial,' which means it is not surrounded by synovial fluid, but it has an adequate blood supply. The PCL is shorter and less oblique than the ACL. The cross-sectional area of the PCL.

Oblique Ligament - an overview ScienceDirect Topic

Despite being the largest ligament on the posterior aspect of the knee, relatively little is known about the normal morphology of the oblique popliteal ligament (OPL). The aim of this study was to investigate the detailed anatomy of the OPL in cadavers and healthy volunteers. The posterior knee was investigated in 25 cadaver lower limbs (mean age 76 ± 9.5 years; 7 men) by dissection. The arcuate popliteal ligament is located in close proximity to the fibular collateral ligament, the oblique popliteal ligament, and the fibula. Last medically reviewed on January 21, 201 The superficial medial collateral ligament (sMCL), the deep medial collateral ligament (dMCL) and the posterior oblique ligament (POL)—a part of the posteromedial capsule (PMC)—are the medial ligamentous stabilisers of the knee against valgus and rotatory loads [2, 8, 10, 24, 32].The MCL is the most frequently injured ligament of the knee [] and can mostly be treated non-surgically with.

The posterior oblique ligament (POL) is the predominant ligamentous structure on the posterior medial corner of the knee joint. A thorough understanding of the anatomy, biomechanics, diagnosis, treatment and rehabilitation of POL injuries will aid orthopaedic surgeons in the management of these injuries. The resulting rotational instability, in addition to valgus laxity, may not be tolerated. The anatomy, function, and surgical repair of the posteromedial capsular and ligamentous structures, called here the posterior oblique ligament, are described on the basis of anatomical dissections of seventeen amputated lower limbs and on the analysis of the operative findings and results of repair in fifty patients treated for ligament and capsular tears in the medial compartment

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. Anatomy Posterior cruciate ligament bundles Traditionally the PCL has been divided into the anterolat-eral bundle comprising about 85% of the bulk, and the posteromedial bundle comprising about 15% of the bulk the oblique transverse ridge. The medio-lateral position of insertion o The associated lesion of the posterior oblique ligament (POL) in the setting of anterior cruciate ligament rupture is quite frequent due to the same rotational mechanism. The diagnosis of POL lesions is challenging, and physical examination is delicate; moreover, they can be easily missed on magnetic resonance imaging. Once recognized, POL lesions must be repaired to restore posteromedial. Purpose: A major structure on the posterior aspect of the knee is the oblique popliteal ligament (OPL). Current literature on the morphology of the ligament is inconsistent and provides minimal quantitative data

anterior oblique ligament, maximum valgus instability occurs at 70° (10). Instability begins at approximately 30° or more of elbow flexion as the unique bony configura­ tion becomes less of a factor and (the elbow unlocks). The posterior oblique segment bundle of the UCL orig­ inates posterior and inferior to the medial epicondyle an Small amount of fluid around the ligaments in this region, also enveloping the distal adductor tendons, and the adductor tubercle. Subtle chondral irregularity of the lateral tibial plateau. Mild knee joint effusion. From the case: Posterior oblique ligament injury. Annotated image The valgus load response of the posterior oblique ligament at 0° of flexion (19.1 N) was significantly higher than at 30° (10.6 N), 60° (7.8 N), and 90° (6.8 N) of flexion. At 0° of knee flexion, the load response to internal rotation on the posterior oblique ligament (45.8 N) was significantly larger than was the response on both. 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 posterior cruciate ligament is located in the backside of the knee joint. Like the Anterior cruciate ligament (ACL), the PCL is intracapsular but 'extra synovial,' which means it is not surrounded by synovial fluid, but it has an adequate blood supply. The PCL is shorter and less oblique than the ACL. The cross-sectional area of the PCL. A. Chwaluk, B. Ciszek, Anatomy of the posterior cruciate ligament composed of many fascicles. Some investigators claim that the PCL has a monofascicular structure [5, 7, 8]. A similar view was presented by Satku et study, the posterior oblique fascicle of the posteri-or cruciate ligament, which has nothing in com 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. The 3 other ligaments form a triangle with 3 points (lateral epicondyle, supinator crest of. The oblique popliteal ligament, the largest posterior knee structure, formed a broad fascial sheath over the posterior aspect of the knee and measured 48.0 mm in length and 9.5 mm wide at its medial origin and 16.4 mm wide at its lateral attachment. It had two lateral attachments, one to the meniscofemoral portion of the posterolateral joint. After confirming the posterior oblique ligament avulsion fracture, the 3.5 mm band anchor was used to reset the posterior oblique ligament avulsion fracture block to the femoral attachment; the ligament tissue was reinforced with the surrounding tissue and the soft tissue of the bone surface was reinforced by a suture with the anchor tail

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) The dorsoradial ligament, posterior oblique ligament, intermetacarpal ligament, and superficial and deep anterior oblique ligaments were best visualized in the sagittal plane (Figs. 2A, and 2B), whereas the UCL was best visualized in the coronal plane

The oblique popliteal ligament (Bourgery ligament) is an expansion of the semimembranosus tendon which originates posterior to the medial tibial condyle and reflects superiorly and laterally to attach on the lateral condyle of the femur The canal lies posterior to the iliopubic tract. The anterior border is formed by the inguinal ligament, the medial border through the lacunar ligament, the posterior border through the pectineal ligament and also the lateral border through the femoral vein. It is a potential space (in the absence of a femoral hernia) The collateral ligaments of the elbow are optimally visualized in a 20° posterior oblique coronal plane in relation to the humeral diaphysis with the elbow extended (Fig. 1) and a coronal plane aligned with the humeral diaphysis with the elbow flexed 20 to 30° 4. Discussion. Despite the fact that nearly 60 percent of anatomical texts and atlases as well as over 90 percent of specialty journal articles state that the distal semimembranosus tendon contributes fibers to the oblique popliteal ligament; none have hypothesized that this structure is itself a tendon [1-31].A macroanalysis using deep dissection of the posterior knee revealed that the OPL.

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 Ligaments of the Lumbar Spine and Pelvis. This blog post article is an overview of the ligaments of the lumbar spine and pelvis.For more complete coverage of the structure and function of the low back and pelvis, Kinesiology - The Skeletal System and Muscle Function, 3 rd ed.

As with the muscles, it is also helpful to know the ligaments of the lumbar. - 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 with extreme flexion tension forces. 25, 26 The intertransverse ligament attaches to the adjacent transverse process and becomes taut predominantly with lateral flexion to the opposite side and to a lesser degree with rotation. 5 The. The imaging anatomy of the medial and lateral supporting structures of the knee has been previously described [1-3].Normal anatomy and pathology of structures making up the posteromedial and posterolateral corners of the knee have also been discussed [].However, to our knowledge no articles have directly addressed the posterior capsular area of the knee at the level of the popliteal fossa

calcaneofibular ligament (CFL) posterior talofibular ligament (PTFL). The ATFL runs from the lateral malleolus anteriorly to the lateral border of the talus. It has a transverse orientation and is best seen on axial images. This is the most commonly injured ligament of the ankle and it is also the first to be injured on the lateral side The ligament originates from a broad anteroinferior surface of the epicondyle. 65 The ulnar nerve rests on the posterior aspect of the medial epicondyle but is not intimately related to the fibers of the anterior bundle of the medial collateral ligament itself. This has obvious implications with regard to the treatment of ulnar nerve. Posterior border.
