Group MCLC 3 (8%) resembled the normal group but had an additional band passing from the posterior capsule to the oblique or transverse band. A spectrum of instability Clin Orthop Relat Res 1992; (280): 186-97.]. ", "It is a modern trend for publishers to establish open access journals. An anatomic study with radiographic correlation Clin Orthop Relat Res 1995; 320: 154-8. Capitellum. The ulnar collateral ligament originates from the medial epicondyle, and attaches to the coronoid process and olecranon of the ulna. Bone and Joint. In the otherwise intact elbow, absence of the radial head does not significantly alter the three-dimensional characteristics of motion in the elbow joint. The humeral origin of the medial collateral ligament (MCL) is reported to be located eccentrically with respect to the axis of rotation of the joint. The ulnar collateral ligament of the human elbow joint. A study in cadavera J Bone Joint Surg Am 1998; 80(6): 879-8.]. Sojbjerg JO, Ovesen J, Nielsen S. Experimental elbow instability after transection of the medial collateral ligament Clin Orthop Relat Res 1987; 218: 186-90. The LCL is poorly demarcated and runs from the lateral epicondyle to the annular ligament. Hildebrand KA, Patterson SD, King GJ. ", "Open access journals are probably one of the most important contributions to promote and diffuse science worldwide. The anterior and posterior bands of the anterior bundle (AMCL) tighten in reciprocal fashion as the elbow is flexed and extended; they are separated by isometric fibres (arrows). Together these ligaments provide the main source of stability for the elbow, holding the humerus and the ulna tightly together. Eygendaal D, Verdegaal SH, Obermann WR, van Vugt AB, Pöll RG, Rozing PM. The elbow joint consists of two types of articulations and thus allows two types of motion. The ulnar collateral ligament of the human elbow joint. According to Schwab’s article, the lateral collateral ligament (LCL) runs from the lateral epicondyle to the annular ligament (AL) without attachments to the ulna, so the lateral ulnar collateral ligament (LUCL) and the accessory lateral ligament were not described. Biomechanical aspects of the elbow are considered in the context of motion, function, and stability. If you do not agree to the foregoing terms and conditions, you should not enter this site. The distal tendons of three elbow flexors (biceps, brachialis and brachioradialis), the principal extensor (triceps) and the pronator teres were connected to steel cables and could be selectively and sequentially loaded to generate the desired motion. Muscular constraints: Muscular forces across the elbow joint enhance elbow stability and limit PLRI. ", "The widest possible diffusion of information is critical for the advancement of science. ", "It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. Articular and ligamentous contributions to the stability of the elbow joint Am J Sports Med 1983; 11(5): 315-9. Bryce CD, Armstrong AD. ], 60-70° of flexion [42Sojbjerg JO, Ovesen J, Nielsen S. Experimental elbow instability after transection of the medial collateral ligament Clin Orthop Relat Res 1987; 218: 186-90. The ulna collateral ligament, on the medial side of the elbow, connects the ulna to the humerus. ", "Open access journals make up a new and rather revolutionary way to scientific publication. The medial ligament has three elements the anterior band (which is most importa… A good example of this is the support provided by the rotator cuff muscles, which keep the head of the humerus in the shallow glenoid cavity of the scapula. Kamineni S, Hirahara H, Neale P, O'Driscoll SW, An KN, Morrey BF. It includes prominent landmarks such as the olecranon, the elbow pit, the lateral and medial epicondyles, and the elbow joint. When performing a surgical procedure at the lateral side of the elbow joint, either the LUCL or the LCL should remain intact to prevent posterolateral rotatory instability [50Dunning CE, Zarzour ZD, Patterson SD, Johnson JA, King GJ. The important ligaments of the elbow are the medial collateral ligament (on the inside of the elbow) and the lateral collateral ligament (on the outside of the elbow.)

If there is a loss of tone, such as in old age or stroke, the shoulder can dislocate. Despite this low recurrence rate, surgeons prefer long immobilisation to prevent instability over early functional treatment to prevent restricted range of motion [6de Haan J, Schep NWL, Peters RW, Tuinebreijer WE, den Hartog D. Simple elbow dislocations in the Netherlands: what are Dutch surgeons doing? The study of Stavlas and co-workers involved use of the Orthofix elbow external fixator (Orthofix, Verona, Italy) and showed that the hinged external fixator restored the stability of the unstable elbow joint after division of the LCL and MCL in eight cadaveric elbow joints [59Stavlas P, Jensen SL, Sojbjerg JO. Correctly label the following anatomical features of the knee joint. It is classed as a hinge-type synovial joint. This stability is provided primarily by the jaw-like trochlear notch of the ulna interlocking with the spool-shaped trochlea of the humerus (Figure 5-6). This stability is provided primarily by the jaw-like trochlear notch of the ulna interlocking with the spool-shaped trochlea of the humerus (Figure 5-6). Consequently, splinting and passive mobilisation for the MCL-deficient elbow should be performed with the forearm in supination. The anaesthetic allows the muscles around the joint to be relaxed enough for the joint to sublux or be dislocated by the examiner to prove the diagnosis. Cage DJ, Abrams RA, Callahan JJ, Botte MJ. The important ligaments of the elbow are the medial collateral ligament (on the inside of the elbow) and the lateral collateral ligament (on the outside of the elbow.) Reliability of range-of-motion measurement in the elbow and forearm J Shoulder Elbow Surg 1998; 7(6): 573-80.]. This hinge-like joint limits the motion of the elbow to flexion and extension.

The elbow and its disorders. The elbow is considered a complex joint, and thus the elements contributing to stability of the elbow are no less intricate. The elbow joint is composed of the articulation between the distal humerus and the proximal radius and ulna. The bony insertion had an average length of 26.3 mm, with its proximal margin an average distance of 11 mm to the coronoid tip. The annular ligament of the superior radio-ulnar joint J Anat 1958; 92(3): 473-82. Typically, tennis players experience pain in the lateral epicondyle from the common extensor origin.

The ulnar collateral ligament is usually torn and there can also be ulnar nerve involvement. Cage et al. The anterior band of the AMCL is taut in extension and relaxed in flexion; the posterior band of the AMCL behaves in a reciprocal fashion. N2 - The stabilizing structures of the elbow that resist valgus stress were studied with a tracking device in a model simulating active motion and muscle activity. If the lateral ligament complex is suspected to be injured after an acute injury, stabilization of the elbow in pronation with a hinged brace should be implemented for 4-6 weeks. Eygendaal D, Olsen BS, Jensen SL, Seki A, Sojbjerg JO. As a result, the neurovascular examination and documentation of all patients presenting with these injuries is vital. Elbow dislocations are classified as simple or complex [3Hildebrand KA, Patterson SD, King GJ. the MCL is composed of the anterior, posterior and transverse bundles; the MCL provides resistance to valgus and distractive stresses; anatomy. The outer bony prominence of the elbow is the lateral epicondyle, a part of the humerus bone. A remarkable result of this study is that the transverse or oblique band of the MCLC is not poorly developed, as reported earlier [16Morrey BF, An KN. Like all synovial joints, the elbow joint has a capsule enclosing the joint.
