stability of elbow joint

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 flexor muscles originate from the medial epicondyle, and the extensor muscles from the lateral. The literature search retrieved 108 studies. Seki et al. There are many bursae in the elbow, but only a few have clinical importance: The joint capsule of the elbow is strengthened by ligaments medially and laterally. A biomechanical analysis of axial loading J Bone Joint Surg Am 2000; 82-A(12): 1749-53. AU - Morrey, B. F. AU - Tanaka, S. AU - An, K. N. PY - 1991. For patients who are able to modify their activities, surgery may not be necessary. A bursa is a membranous sac filled with synovial fluid. 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? An elbow dislocation usually occurs when a young child falls on a hand with the elbow flexed. Stability therefore depends on muscular support on the medial and lateral aspects by the subscapularis, teres minor, infraspinatus, and supraspinatus. Takigawa et al. Deutch SR, Jensen SL, Olsen BS, Sneppen O. Elbow joint stability in relation to forced external rotation: An experimental study of the osseous constraint J Shoulder Elbow Surg 2003; 12(3): 287-92. The elbow is a complex, highly constrained joint that provides critical range of motion to the upper extremity needed for performing the normal activities of daily living. 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. In five of the ten specimens, the LUCL runs from the lateral epicondyle to the crista m. supinatoris of the ulna. Posterolateral rotatory instability of the elbow J Bone Joint Surg Am 1991; 73(3): 440-6. In the second study, the maximum joint laxity in forced varus and external rotation (supination) occurred between 90-110° of flexion [47Olsen BS, Sojbjerg JO, Dalstra M, Sneppen O. Kinematics of the lateral ligamentous constraints of the elbow joint J Shoulder Elbow Surg 1996; 5(5): 333-41.]. Patients with gross instability did not allow quantitative measurements of joint angulation as a result of early dislocation during stability testing (group 3, excluded). Only type III fractures are large enough to include the brachialis tendon insertion and the AMCL insertion. If the elbow is stable in pronation, the AMCL can be assumed to be intact and the elbow can be treated immediately with a hinged cast-brace, with the forearm in full pronation. Reduction of a posterior elbow dislocation should be carried out with a lax LCLC and therefore with a supinated forearm. Overview. The medial collateral ligament of the elbow joint: anatomy and kinematics J Shoulder Elbow Surg 1998; 7(4): 345-51.]. This device is implanted subcutaneously about the elbow joint, allowing unrestricted joint motion while avoiding the complications inherent to other methods. A primary constraint is defined as a constraint where release causes laxity, and a secondary constraint is a constraint where release alone is insufficient to cause laxity, but where release after division of the fist constraint increases the laxity of the joint. The primary stability of the elbow is provided by the ulnar collateral ligament, located on the medial (inner) side of the elbow. The elbow is protected by a fortress of individual static and dynamic constraints that function together to provide stability. It is known as a trochleogingylomoid joint as it can flex and extend as … In all specimens, the AMCL was a distinct structure with a macroscopically visible ridge between the anterior and posterior bands. In the elbow joint, this specifically means that the static part is mainly provided by the congruency between the articulating surfaces at the elbow joint. In this later anatomical study, the LUCL was observed in all 17 examined fresh-frozen elbows [18O'Driscoll SW, Horii E, Morrey BF, Carmichael SW. Anatomy of the ulnar part of the lateral collateral ligament of the elbow Clin Anat 1992; 5: 296-303.]. Many of the author’s insights were later proven to be true in studies on elbow joints of human anatomic specimens. To access the TeachMeAnatomy 3D Model, you must be a premium subscriber. 20. Halls AA, Travill A. Group MCLC 4 (15%) exhibited a pattern that was a combination of that exhibited in groups 2 and 3. Therefore, load transfer is dependent on the rotational position of the forearm, the amount of flexion, and the varus or valgus position of the elbow. Morrey BF, An KN, Stormont TJ. Capitellum. 414-32. The elbow is the joint connecting the upper arm to the forearm. The first is that the arbitrarily flexed position of the elbow may not actually be in a position of stability. Elbow dislocations In: Morrey BF, Ed. Necessary cookies are absolutely essential for the website to function properly. Share. You also have the option to opt-out of these cookies. A prospective randomized study J Bone Joint Surg Am 1987; 69(4): 605-8., 11Josefsson PO, Johnell O, Wendeberg B. Ligamentous injuries in dislocations of the elbow joint Clin Orthop Relat Res 1987; 221: 221-5.]. 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. Reliability of range-of-motion measurement in the elbow and forearm J Shoulder Elbow Surg 1998; 7(6): 573-80.]. The AMCL is a stronger ligament than the PMCL and acts as the major medial ligamentous joint stabiliser. 7). The tone of the surrounding muscles contributes greatly to the stability of a joint. The operated cases in these studies (n=78) were all explored at the medial side of the elbow. The radial collateral ligament, on the lateral elbow, connects the radius to the humerus. Although the range of motion decreased, the extensor and fixator forced the unstable joint toward the varus position, as compared with the intact elbow. The brachialis, biceps, and triceps increase osseous stability as they compress the joint and assist with varus and valgus stability. The transverse part of the MCL is also called Cooper’s ligament [17Fuss FK. examined the anatomy of the anterior bundle of the medial collateral ligament (AMCL) in 28 anatomic specimens [24Callaway GH, Field LD, Deng XH, et al. [caption id="attachment_5050" align="aligncenter" width="480"], [caption id="attachment_33074" align="aligncenter" width="829"], [caption id="attachment_10458" align="alignright" width="283"]. Philadelphia: Lea & Febiger 1918.]. A supracondylar fracture usually occurs due to a fall onto on outstretched, extended hand in a child (95%) but more rarely can occur by a direct impact onto a flexed elbow. Group MCLC 1 (49%) was the normal group with classic AMCL, PMCL and transverse or oblique band anatomy. ], AMCL at 30-40° and entire MCL at 80-100° of flexion [27Floris S, Olsen BS, Dalstra M, Sojbjerg JO, Sneppen O. Instability can be classified, according to the timing, as acute or chronic instability or recurrent dislocation. Sportspersons can develop an overuse strain of the common tendon – which results in pain and inflammation around the area of the affected epicondyle. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community. Elbow subluxation and dislocation. This preference is valid because it is easier to treat stiffness than instability of the elbow joint. The stability and biomechanics of the elbow joint have been examined in numerous studies of human anatomic specimens [13Bryce CD, Armstrong AD. In two of these studies, varus stress was evaluated as well and was present in 39% (24/61) of all patients. Golfers experience pain in the medial epicondyle from the common flexor origin. Stability of the elbow joint is provided by the osseous articulations, medial and lateral collateral ligaments, and traversing muscles. 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. Most of the flexor and extensor muscles in the forearm have a common tendinous origin. N-m across the elbow joint. Which of the following joints is the least stable? Open access journals offer a good alternative for free access to good quality scientific information. Efficacy of ligament repair and radial head prosthetic replacement: a cadaver study J Bone Joint Surg Br 2003; 85(7): 1006-.]. Elbow stability is determined by Bony factors Ligamentous factors Muscular factors Stabilising factors can be categorised as : Primary stabilisers MCL LCL Coronoid process Secondary stabilisers Head of radius Posterolateral capsule Anconeus muscle Concept This LUCL was already described in 1958 by Martin as a bundle, but without naming it: “a definite bundle which normally crosses the annular band and gains attachment to the supinator crest, frequently to a special tubercle on that crest” [19Martin BF. Dunning CE, Zarzour ZD, Patterson SD, Johnson JA, King GJ. performed a study with simulated active motion and found that in patients with acute posterolateral rotatory instability after elbow dislocations and in patients with extended lateral surgical exposures, passive elbow flexion with the forearm in pronation can be used in rehabilitation because forearm pronation stabilised the LCL-deficient elbow [35Dunning CE, Zarzour ZD, Patterson SD, Johnson JA, King GJ. The elbow joint functions as a link between the arm and forearm to position the hand in space and allow activities of prehension; it transmits forces and it allows the forearm to act as a lever in lifting and carrying. The anterior part of the MCL contained some fibres that were taut in full extension and some that were taut in any position (isometric fibres). reported persistent medial instability on dynamic radiographs with valgus loads after an average of 9 years after a simple dislocation. 4). The coupled forearm rota- tion measured with valgus-varus loading was defined as rotatory laxity. Most elbow dislocations are posterior, and it is important to note that elbow dislocations are named by the position of the ulna and radius, not the humerus. 2. MedSchool. With the arm in vertical orientation and the forearm in supination, sectioning of the LCL increased rotatory instability compared to values obtained with the forearm in pronation and with the intact LCL. Subtle radiographic signs of subluxation. The LUCL adhered closely to the supinator and extensor muscles, its intermuscular fascia and the anconeus muscle. 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. The ulnar collateral ligament of the human elbow joint. Netherlands J Traumatol 2009; 17(5): 124-7.]. Relationship to medial instability J Bone Joint Surg Am 2000; 82(4): 555-60. Direct damage, or swelling can cause the interference to the blood supply of the forearm via the brachial artery. Apply valgus stress while going from flexion to extension and back. Microscopically, the LUCL was a slender and vague structure and consisted of the thick area of the capsuloligamentous layer. Elbow subluxation and dislocation. There also can be damage to the medial, ulnar or radial nerves. Dunning et al. Capitellum. Markolf KL, Lamey D, Yang S, Meals R, Hotchkiss R. Radioulnar load-sharing in the forearm. Subtle radiographic signs of subluxation. This is easily remembered as golfers aim for the 'middle' of the fairway, while tennis players aim for the 'lateral' line of the court! Philadelphia: WB Saunders Company 2010; pp. The AMCL and LCL were taut throughout almost the entire range of flexion. 2. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. Schwab GH, Bennett JB, Woods GW, Tullos HS. This in itself is strong and fibrous, strengthening the joint. Netherlands J Traumatol 2009; 17(5): 124-7. Primary and secondary constraints to elbow joint stability. In varus alignment of the elbow, defined as no contact between the radial head and capitellum, the load was transferred to the ulnohumeral joint in 93% of patients. However, valgus displacements occurred during a load of seven Newtons after either sectioning the LCL or MCL and occurred during every load after sectioning both the LCL and MCL. The LUCL ran from the inferior part of the lateral epicondyle and blended with the AL. The outer bony prominence of the elbow is the lateral epicondyle, a part of the humerus bone. Simulated active control produces repeatable motion pathways of the elbow in an in vitro testing system J Biomech 2001; 34(8): 1039-48., 37Johnson JA, Rath DA, Dunning CE, Roth SE, King GJ. Subluxation can be subtle. Posterolateral rotatory instability of the elbow J Bone Joint Surg Am 1991; 73(3): 440-6. -----Want more info like this? Cage DJ, Abrams RA, Callahan JJ, Botte MJ. Beingessner and co-workers advise repair of coronoid fracture type II and III in combination with LCLC repair [56Beingessner DM, Dunning CE, Stacpoole RA, Johnson JA, King GJW. O'Driscoll SW, Bell DF, Morrey BF. Morrey BF, An KN. A kinematic study Acta Orthop Scand 1999; 70(1): 6-8. The PMCL was taut only when the elbow was in a flexed position. The elbow joint consists of two types of articulations and thus allows two types of motion. This hinge-like joint limits the motion of the elbow to flexion and extension. Functional anatomy of the lateral collateral ligament complex of the elbow: configuration of Y and its role J Shoulder Elbow Surg 2002; 11(1): 53-9.]. During rehabilitation, the preferred position of the forearm is supination. Simulation of elbow and forearm motion, Armstrong AD, Dunning CE, Faber KJ, Duck TR, Johnson JA, King GJ. Functional anatomy of the ligaments of the elbow Clin Orthop Relat Res 1985; 201: 84-90.]. The elbow has inherent articular stability at the extremes of extension and flexion.In full extension, the humeroulnar joint is in a close-packed position. Closkey RF, Goode JR, Kirschenbaum D, Cody RP. The elbow is the visible joint between the upper and lower parts of the arm. Tanaka S, An K-N, Morrey BF. The anatomy and role of the lateral stabilizers J Bone Joint Surg Am 1997; 79(2): 225-33.]. Make the changes yourself here! 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. Jensen SL, Olsen BS, Seki A, Ole SJ, Sneppen O. Radiohumeral stability to forced translation: an experimental analysis of the bony constraint J Shoulder Elbow Surg 2002; 11(2): 158-65. Assessment of elbow stability. The outer bony prominence of the elbow is the lateral epicondyle, a part of the humerus bone. Beingessner DM, Stacpoole RA, Dunning CE, Johnson JA, King GJ. Deutch SR, Olsen BS, Jensen SL, Tyrdal S, Sneppen O. Ligamentous and capsular restraints to experimental posterior elbow joint dislocation Scand J Med Sci Sports 2003; 13(5): 311-6. Beckett KS, McConnell P, Lagopoulos M, Newman RJ. Group MCLC 3 (8%) resembled the normal group but had an additional band passing from the posterior capsule to the oblique or transverse band. Nielsen and Olsen observed no influence of capsule puncture or transection of the anterior and/or posterior capsule on joint laxity in any studied direction or on the pivot-shift test [49Nielsen KK, Olsen BS. The medial collateral ligament of the elbow joint: anatomy and kinematics J Shoulder Elbow Surg 1998; 7(4): 345-51. ", "Open access journals are probably one of the most important contributions to promote and diffuse science worldwide. Therefore, a final conclusion with regard to the best position is not possible; the positions with the greatest laxity were: 90° of flexion [41Morrey BF, An KN. The elbow joint is composed of the articulation between the distal humerus and the proximal radius and ulna. The elbow is a complex joint whose stability is imparted by osseous as well as soft-tissue constraints, and injuries often involve several of these structures. Nielsen KK, Olsen BS. This option opens several quite interesting possibilities to disseminate openly and freely new knowledge and even to facilitate interpersonal communication among scientists. He also concluded that the posterior part of the MCL was taut when the elbow was fully flexed. Rehabilitation of the medial collateral ligament-deficient elbow: an in vitro biomechanical study J Hand Surg Am 2000; 25(6): 1051-7.]. Effectiveness of the lateral unilateral dynamic external fixator after elbow ligament injury J Bone Joint Surg Am 2007; 89(8): 1802-9. Biomechanical evaluation of the medial collateral ligament of the elbow J Bone Joint Surg Am 1997; 79(8): 1223-31.]. Its nerve supply is provided by the median, musculocutaneous and radial nerves anteriorly, and the ulnar nerve posteriorly. Clinical Relevance: Injuries to the Elbow Joint. Surgeons treating elbow dislocation are concerned about two complications: stiffness and instability of the elbow joint. Share. When interpreting biomechanical studies, it is important to distinguish between studies with or without simulation of active muscle loading. Try again to score 100%. The influence of muscle loading on joint stability was determined by measuring the joint laxity both with and without the addition of simulated muscle loading. The smallest distance between the attachment sites of the AMCL on the medial epicondyle and the ulna was found on the lateral aspect of the attachment site of the AMCL on the medial epicondyle. (3), was not identified. These cookies will be stored in your browser only with your consent. The second is that the elbow joint becomes stiff very rapidly in a matter of days, far quicker than the time required for the soft tissues to heal enough to provide adequate stability. Bryce CD, Armstrong AD. ], 70-90° of flexion, and forearm in pronation or neutral forearm rotation (to prevent radial head luxation in cases of additional LCLC lesions) [44Eygendaal D, Olsen BS, Jensen SL, Seki A, Sojbjerg JO. Kinematics of partial and total ruptures of the medial collateral ligament of the elbow J Shoulder Elbow Surg 1999; 8(6): 612-. *Reprinted from Journal of Bone and Joint Surgery American, 1997, volume 79, 2, Rotatory instability of the elbow. Original Author(s): Oliver Jones Last updated: January 22, 2019 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.) The radial collateral ligament is found on the lateral side of the joint, extending from the lateral epicondyle, and blending with the annular ligament of the radius (a ligament from the proximal radioulnar joint). Anatomy and biomechanics of the elbow Orthop Clin North Am 2008; 39(2): 141-54. advised active motion for the MCL elbow during the early stages of healing because active motion provides stability similar to that of an intact joint [38Armstrong AD, Dunning CE, Faber KJ, Duck TR, Johnson JA, King GJ. Muscle forces and pronation stabilize the lateral ligament deficient elbow Clin Orthop Relat Res 2001; 388: 118-24. It includes prominent landmarks such as the olecranon, the elbow pit, the lateral and medial epicondyles, and the elbow joint. Effectiveness of the lateral unilateral dynamic external fixator after elbow ligament injury J Bone Joint Surg Am 2007; 89(8): 1802-9.]. The ulnar collateral ligament of the human elbow joint. The elbow joint is where the distal humerus meets the proximal radius and ulna bones. A spectrum of instability Clin Orthop Relat Res 1992; (280): 186-97.]. Morrey and An studied the functional anatomy of the ligaments of the elbow in ten fresh-frozen upper extremities and a quantitative dissection and described the collateral ligaments (Fig. ", "It is a modern trend for publishers to establish open access journals. The elbow is considered a complex joint, and thus the elements contributing to stability of the elbow are no less intricate. No recurrent elbow dislocations were noted [12Eygendaal D, Verdegaal SH, Obermann WR, van Vugt AB, Pöll RG, Rozing PM. Transmission of pressures acroos the elbow joint Anat Rec 1964; 150: 243-7.].

Identification of elbow subluxation or dislocation. Like all synovial joints, the elbow joint has a capsule enclosing the joint. Abnormal If ; Increased laxity of the joint. Cohen et al. origin. However, during the activities of daily living, valgus stress is rare and short, while most functions generate a sustained varus stress. The primary constraints are the anterior medial collateral ligament (AMCL), the lateral collateral ligament complex (LCLC) and the ulnohumeral articulation.

Kamineni S, Hirahara H, Neale P, O'Driscoll SW, An KN, Morrey BF. ulnohumeral joint (coronoid) loss of 50% or more of coronoid height results in elbow instability; medial (ulnar) collateral ligament (MCL) overview . One hand is just above the elbow joint and other hand is placed on the wrist. Schneeberger AG, Sadowski MM, Jacob HA. 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. Rotatory instability with the forearm pronated was reduced significantly when active flexion was simulated. The elbow is composed of three separate joints, between three bones, and ligaments that provide stability. In the elbow joint, this specifically means that the static part is mainly provided by the congruency between the articulating surfaces at the elbow joint. Dunning et al. The two important ligaments are the lateral (outside) ligament and ulnar (inside) collateral ligament. ", "Open access journals have become a fundamental tool for students, researchers, patients and the general public.
