To produce an anterior dislocation of the radial head, the orbicular ligament, the posterior border of the Denucd ligament, and the proximal Xi to ?4 of the interosseous membrane (including Weitbrecht’s oblique cord) must Each of these structures contributes to the stability of the elbow joint. Wrist ligaments are best assessed with dedicated wrist MRI. Type classification was performed by focusing on the positional relationship between POL morphology and the joint capsule. This ligament com-plex is divided into the anterior oblique ligament (the anterior bundle of the medial ulnar collateral ligament com-plex), the posterior oblique ligament, and the transverse ligament9,10 (Fig. Effect of sectioning the posterior cruciate ligament and posterolateral structures.. The anterior oblique ligament (AOL) or bundle, posterior oblique ligament (POL) or bundle, and the transverse ligament (which unites the AOL and POL). 3-11 ). ligament, the anterior elbow capsule and the tendon of the brachialis muscle. Capsule is a secondary stabilizer. Author information: (1)Institute for Human Movement and Medical Sciences, Niigata University of Health and Welfare, Shimami-cho 1398, Kita-ku, Niigata City, 950-3198, Japan. The oblique cord is a ligament between the ulnar and radius bones in the lower arm near the elbow.It takes the form of a small, flattened band, extending downward and lateralward, from the lateral side of the ulnar tuberosity at the base of the coronoid process to the radius a little below the radial tuberosity. cuffs head of radius ... 3 parts: anterior band, posterior band, oblique band (goes across) bursae. The examination should include both transverse and longitudinal ... lenging due to its steep oblique course and 90° rotation (9). The elbow articulations are stabilized by the medial (ulnar) and lateral (radial) collateral ligament complexes . The medial elbow joint is stabilized by the ulnar collateral ligament, of which the anterior bundle is most important, extending from the humerus anteriorly to the sublime tubercle and several centimeters distal along the ulna ( Fig. The AOL is the strongest elbow collateral ligament with an average failure load of 260 N . Greatest capacity of elbow occurs at 80 degrees flexion and is 25-30 ml. The MCL complex consists of three ligaments: the anterior oblique (AOL), posterior oblique (POL), and transverse Ra’KerryK. The mean length of the AOL is 27.1 mm and of the POL, 24.2 mm; the mean widths are about 4.7 mm and 5.3 mm, respectively. [1, 2] Trauma and postdislocation injuries are other common causes of collateral ligament injury, which can occur on either side of the joint. The purpose of this basic research study was to clarify the morphological characteristics of the posterior oblique fibers (POL) of the ulnar collateral ligament using a large number of specimens. Ulnar collateral ligament (UCL) complex. (A) Left elbow.

Th e lateral elbow complex consists of 4 structures. Medially, the medial collateral ligament consists of the anterior oblique ligament (AOL), the posterior oblique ligament (POL), and the transverse ligament , ( Fig. transverse (or oblique) bundle (Cooper's ligament) runs between the inferior fibers of the anterior and posterior bundles (i.e. elbow specimens. ... dog, medial collateral ligament, oblique ligament, elbow, ... Strocchi et al. Other components of the ulnar collateral ligament include posterior and oblique bundles. The ulnar collateral ligament (UCL), particularly the anterior portion of the anterior oblique ligament, is the primary static contributor to elbow valgus stability. accessory ligament (a.k.a. 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. Each group has an arc through which the majority of its fibers are taut. This arc changes slightly if varus or valgus stress is imposed upon the elbow joint (9). Note that this ligament is also referred to as the medial collateral ligament and should not be confused with the lateral ulnar collateral ligament (LUCL). 1 = anterior oblique ligament (AOL); 2 = posterior oblique ligament (POL); 3 = transverse band. BACKGROUND: The medial collateral ligament of the elbow joint consists of the anterior oblique ligament (AOL), posterior oblique ligament (POL), and transverse ligament (TL). The intrinsic and extrinsic wrist ligaments play a vital role in the stability of the wrist joint. Abstract Elbow medial collateral ligament sprain occurs when the elbow is subjected to a valgus force exceeding the tensile properties of the medial collateral ligament (MCL). Role of the oblique ligament in the integrity of the medial collateral ligament of the canine elbow joint . The anterior oblique ligament's Morphological features of the posterior oblique ligament of the ulnar collateral ligament of the elbow joint. FIGURE 3: The posterior fibers of the ulnar collateral ligament become tight during elbow flexion. Various studies have been conducted on the kinematics of elbow joints after ligament cutting; however, no biomechanical studies have measured the tension applied to the ligament. A study of 30 cadaveric elbow specimens yielded similar results. No simple classification for elbow instability exists, but rather a set of criteria are considered for diagnosis and treatment.

Elbow Sports Injury Specific Special Tests • Anterior •Biceps Tendon • Medial & Posterior •Flexor-Pronator •Ulnar Collateral Ligament •Posteromedial Impingement •Ulnar Nerve •Triceps Tendon • Lateral •Extensor Tendon •Posterolateral Rotatory Instability [2] The anterior portion , directed obliquely forward, is attached, above, by its apex, to the front part of the medial epicondyle of the humerus ; and, below, by its broad base to the medial margin of the coronoid process of the ulna . Functionally, the anterior oblique has been divided into three groups of fibers or bands: anterior, middle, and posterior. This study aimed to clarify the structure of the TL, with a focus on the continuity between the TL and AOL. sion, the UCL, anterior joint cap Elbow collateral ligament insufficiency is commonly seen in sports participants involved in overarm-throwing sports such as cricket, baseball, and tennis.

Shimizu S(1), Edama M(2)(3), Ikezu M(1), Matsuzawa K(1), Kaneko F(1), Kageyama I(4). They found that isolated transection of the anterior bundle of the ulnar collateral ligament resulted in significant joint instability that was not reproducible with isolated transection of the posterior oblique bundle or the joint capsule. UCL injuries are most common in athletes participating in overhead sports. force at the elbow. FIGURE 2: The anterior fibers of the ulnar collateral ligament remain taut during elbow extension. The AOL of the MCL is the most important stabilizer to valgus stresses and should be preserved or reconstructed. The medial collateral ligament originates from the anterior inferior surface of the medial epicondyle and joins the ulna to the humerus, providing support and resistance in valgus overloads. 1). The medial collateral ligament (MCL) complex is made up of anterior, posterior, and transverse bundles. medial olecranon to medial coronoid process) almost no role in elbow stabilization; Variant anatomy. There are numerous ligaments but included below are the most clinically significant. Th e oblique band of the MUCL does not technically cross the elbow joint and this does not provide extensive stabilization to the medial elbow like the anterior and posterior bands. This was a cadaveric and anatomic study and the authors didn’t analyze the role of the different components of the lateral elbow ligaments in elbow stability. Separated into three bundles, the Anterior Oblique Ligament (AOL), the Posterior Oblique Ligament (POL), and the Transverse Ligament (Figure 1),11 the UCL provides valgus restraint from 20-120 degrees of elbow flexion.13 The Anterior Oblique Ligament is … ligament, UCL = ulnar (medial) collateral ligament ... anterior elbow, the elbow is extended and the forearm is supinated (Fig 2).
