Stability of the Elbow Joint: Relevant Anatomy and Clinical Implications of In Vitro Biomechanical Studies J. de Haan 1, N.W.L Schep 2, D Eygendaal 3, G-J Kleinrensink 4, W.E Tuinebreijer 2, D. den Hartog *, 2. Therefore forearm pronation stabilised the LCL-deficient elbow during passive flexion with the arm in the vertical orientation. The anterior and posterior bands of the AMCL tighten in reciprocal fashion during flexion and extension of the elbow. ", "Open Access 'Chemistry' Journals allow the dissemination of knowledge at your finger tips without paying for the scientific content. repeated the former study in ten cadaveric upper extremities, but instead of the LCL, the MCL (AMCL and PMCL) was sectioned to generate valgus instability [38Armstrong AD, Dunning CE, Faber KJ, Duck TR, Johnson JA, King GJ. T1 - Valgus stability of the elbow. Valgus Stability Test . A complex joint, the elbow serves as a link in the lever arm system that positions the hand, as a fulcrum of the forearm lever, and as a load-carrying joint. Coronoid process and radial head as posterolateral rotatory stabilizers of the elbow J Bone Joint Surg Am 2004; 86-A(5): 975-82.]. An anatomic study with radiographic correlation Clin Orthop Relat Res 1995; 320: 154-8. 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). The resulting ischaemia can cause Volkmann’s ischaemic contracture – uncontrolled flexion of the hand, as flexors muscles become fibrotic and short. 5). The elbow joint is composed of the articulation between the distal humerus and the proximal radius and ulna. Rotatory instability with the forearm pronated was reduced significantly when active flexion was simulated. The arterial supply to the elbow joint is from the cubital anastomosis, which includes recurrent and collateral branches from the brachial and deep brachial arteries. However, during the activities of daily living, valgus stress is rare and short, while most functions generate a sustained varus stress. However, even an isolated coronoid process fracture type III can lead to a posterior subluxation, especially during 60 -105° elbow flexion [55Closkey RF, Goode JR, Kirschenbaum D, Cody RP. Mobility and stability of the elbow joint are necessary for daily, recreational, and professional activities. Our 3D anatomical model provides you with hands-on, interactive and valuable learning tool right here on your device. The coupled forearm rota- tion measured with valgus-varus loading was defined as rotatory laxity. 1 Department of Surgery-Traumatology, Westfriesgasthuis, P.O. O'Driscoll SW, Morrey BF, Korinek S, An KN. Dunning CE, Duck TR, King GJ, Johnson JA. Valgus stability is present post reduction in the pronated forearm in all but stage 3 These are treated by immediate unlimited flexion / extension in a cast brace, applied with the forearm in full pronation in stage 3 If elbow is unstable in extension Consequently, splinting and passive mobilisation for the MCL-deficient elbow should be performed with the forearm in supination. There also can be damage to the medial, ulnar or radial nerves. The ulnar collateral ligament of the human elbow joint. The transverse part of the MCL is also called Cooper’s ligament [17Fuss FK. The flexor muscles originate from the medial epicondyle, and the extensor muscles from the lateral. Magnetic resonance imaging combined with arthrography revealed that 42% (n=19 tested) of these cases with medial instability on dynamic radiographs had a rupture of the medial collateral ligament. Elbow subluxation and dislocation. ulnohumeral joint (coronoid) loss of 50% or more of coronoid height results in elbow instability; medial (ulnar) collateral ligament (MCL) overview . A separate band from the lateral epicondyle to the ulna, such as the LUCL in Fig. Found an error? Nielsen KK, Olsen BS. No recurrent elbow dislocations were noted [12Eygendaal D, Verdegaal SH, Obermann WR, van Vugt AB, Pöll RG, Rozing PM. ", "Open access journals are a novel concept in the medical literature. O'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. the MCL is composed of the anterior, posterior and transverse bundles; the MCL provides resistance to valgus and distractive stresses; anatomy. This is easily remembered as golfers aim for the ‘middle’ of the fairway, while tennis players aim for the ‘lateral’ line of the court! Tanaka S, An K-N, Morrey BF. Cohen et al. This classification correlated well with the clinical outcome. Stability of the elbow joint is provided by the osseous articulations, medial and lateral collateral ligaments, and traversing muscles. An understanding of the anatomic features contributing to these roles is critical and is outlined in this chapter. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor. The LUCL lies posterior to the LCL and the extensor carpi ulnaris muscle. 414-32. Furthermore, splinting of these elbows should be performed using a brace, with the forearm held in full pronation. Imatani J, Ogura T, Morito Y, Hashizume H, Inoue H. Anatomic and histologic studies of lateral collateral ligament complex of the elbow joint J Shoulder Elbow Surg 1999; 8(6): 625-7. The elbow is the visible joint between the upper and lower parts of the arm. A kinematic study Acta Orthop Scand 1999; 70(1): 6-8. The annular ligament of the superior radio-ulnar joint J Anat 1958; 92(3): 473-82.]. Regan W, Morrey B. Fractures of the coronoid process of the ulna J Bone Joint Surg Am 1989; 71(9): 1348-54. Glenohumeral stability also requires that the capsule and ligaments check the motion of the joint so that it does not rotate to positions where the forces become unbalanced. A laterally applied hinged external fixator protects primarily against varus stress, so valgus stress should be avoided. Coronoid process and radial head as posterolateral rotatory stabilizers of the elbow J Bone Joint Surg Am 2004; 86-A(5): 975-82. This point was near the axis of rotation. The anterior band of the ulnar or medial collateral ligament (MCL) complex is the main static stabilizer of the elbow against valgus and internal rotation stress. Use the information in this article to help you with the answers. The muscles that cross the elbow joint also contribute to the stability of the joint. All authors have read and approved the final manuscript. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community. A study in cadavera J Bone Joint Surg Am 1998; 80(6): 879-8. reported 178 elbow dislocations (simple and complex) in a population of approximately 243,000 persons, making the annual incidence of elbow dislocations in children and adults 6.1 per 100,000 [2Josefsson PO, Nilsson BE. 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. Assessment of elbow stability. Capitellum. The elbow and its disorders. Dr. Ebraheim’s educational animated video describes ligaments of the elbow and stability of the elbow. Open access journals are very helpful for students, researchers and the general public including people from institutions which do not have library or cannot afford to subscribe scientific journals. Left elbow joint with medial collateral ligaments [20Gray H. Anatomy of the human body. It is classed as a hinge-type synovial joint. Fuss also examined the MCL by visual inspection for the presence of taut fibre bundles [17Fuss FK. Schwab GH, Bennett JB, Woods GW, Tullos HS. Golfers experience pain in the medial epicondyle from the common flexor origin. Most of the flexor and extensor muscles in the forearm have a common tendinous origin. The humeroulnar joint provides most of the structural stability to the elbow as a whole. Closkey RF, Goode JR, Kirschenbaum D, Cody RP. Another study with a laterally applied hinged external fixator (Dynamic Joint Distractor II, Stryker Howmedica, Rutherford, New Jersey) was performed by Kamineni et al.

Its nerve supply is provided by the median, musculocutaneous and radial nerves anteriorly, and the ulnar nerve posteriorly. 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.]. Biomechanics of elbow instability: the role of the medial collateral ligament Clin Orthop Relat Res 1980; 146: 42-52.]. [26Imatani J, Ogura T, Morito Y, Hashizume H, Inoue H. Anatomic and histologic studies of lateral collateral ligament complex of the elbow joint J Shoulder Elbow Surg 1999; 8(6): 625-7.]. Gross instability was present after LCL transection during passive elbow flexion, with the arm in the varus orientation. Halls AA, Travill A. The muscles that cross the elbow joint also contribute to the stability of the joint. These in vitro biomechanical studies also have important consequences for diagnosis, treatment and rehabilitation of (post)-traumatic injuries of the elbow joint. The secondary constraints are the radiohumeral articulation, the common flexor-pronator tendon, the common extensor tendon and the capsule. Soft tissue attachments of the ulnar coronoid process. 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 articles are of high quality and broad scope. The elbow was rated as slightly instable in case of less than 10° joint angulation on the medial and/or lateral side (group 1) and as moderate instable in case of more than 10° of joint angulation (group 2). investigated 20 elbows of human anatomic specimens to identify the soft tissue attachments of the coronoid process and correlated this anatomy with the radiographic classification of Regan and Morrey [30Cage DJ, Abrams RA, Callahan JJ, Botte MJ. Soft tissue attachments of the ulnar coronoid process. Therefore splinting and passive mobilisation for the MCL-deficient elbow should be done with the forearm in supination. Because this bursa lies relatively superficially, it can also become infected (e.g cut from a fall on the elbow) The MCL consists of an anterior bundle, AMCL, posterior bundle or PMCL and a transverse ligament; the last structure does not span the joint and therefore does not contribute to stability. Surgeons treating elbow dislocation are concerned about two complications: stiffness and instability of the elbow joint. The accessory collateral ligament of the LCLC was already described in the study by Martin and the study by Morrey and An as the “accessory posterior ligament” [16Morrey BF, An KN. The articles are high standard and cover a wide area. In three studies analysing patients with simple elbow dislocations, all (n=123) were evaluated and classified as unstable for valgus stress, when compared to the uninjured side examined under anaesthesia [9Josefsson PO, Gentz CF, Johnell O, Wendeberg B. Surgical versus non-surgical treatment of ligamentous injuries following dislocation of the elbow joint. Elbow stability results primarily from the integrity of relevant anatomical structures which maintain physiological laxity of the joint. Clinical Relevance: Injuries to the Elbow Joint. 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. Functional anatomy of the ligaments of the elbow Clin Orthop Relat Res 1985; 201: 84-90. Ultrasound imaging can be used to assess medial elbow stability. Note - pronation and supination do not occur at the elbow - they are produced at the nearby radioulnar joints. ], 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. Abnormal If ; Increased laxity of the joint. The two important ligaments are the lateral (outside) ligament and ulnar (inside) collateral ligament. Kinematics of the ligamentous unstable elbow joint after application of a hinged external fixation device: a cadaveric study J Shoulder Elbow Surg 2007; 16(4): 491-6. This option opens several quite interesting possibilities to disseminate openly and freely new knowledge and even to facilitate interpersonal communication among scientists. The elbow joint consists of three separate bones: the humerus (in the upper arm) and the radius and ulna (in the forearm). This study determined the effect of the elbow flexion angle on the medial elbow joint space during clinical tests of medial elbow stability. 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.) Typically, tennis players experience pain in the lateral epicondyle from the common extensor origin. 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. Varus displacements could be prevented with the external fixator. The effect of coronoid fractures on elbow kinematics and stability Clin Biomech 2007; 22(2): 183-90.]. The results for the pivot shift test according to different studies were: supination of the forearm; application of valgus stress and an axial compression force to the elbow while it was flexed from full extension [45O'Driscoll SW, Bell DF, Morrey BF. Share. 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. Group MCLC 4 (15%) exhibited a pattern that was a combination of that exhibited in groups 2 and 3. Isometric fibres are found between the anterior and posterior bands of the AMCL (Fig. Takigawa N, Ryu J, Kish VL, Kinoshita M, Abe M. Functional anatomy of the lateral collateral ligament complex of the elbow: morphology and strain J Hand Surg Br 2005; 30(2): 143-7. The optimal positions for valgus testing in different studies were diverse. 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. Armstrong et al. 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.]. Share. Biomechanical study of ligaments around the elbow joint Clin Orthop Relat Res 1991; 271: 170-9. 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. The dynamic part includes the muscles that cross the elbow joint. The authors advise active motion for the MCL-deficient elbow during the early stages of healing because active motion provides stability similar to that of an intact joint. Anatomy, function and biomechanics J Anat 1991; 175: 203-12. After elbow fracture-dislocation, surgeons confront numerous treatment options in pursuing a stable joint for early motion. Indeed, the research articles span a wide range of area and of high quality. ", "It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. 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). Group MCLC 3 (8%) resembled the normal group but had an additional band passing from the posterior capsule to the oblique or transverse band. Cage DJ, Abrams RA, Callahan JJ, Botte MJ. The anatomy and role of the lateral stabilizers, Cohen MS and Hastings H, 225-233, with permission from Rockwater and Journal of Bone and Joint Surgery. This is in contrast with the physiology of the joint, in which the flexion-extension axis of the elbow joint is not constant during motion. Sportspersons can develop an overuse strain of the common tendon – which results in pain and inflammation around the area of the affected epicondyle. Following transection of the MCL, the elbow was more stable in supination than pronation during passive flexion. N-m across the elbow joint. Biomechanical evaluation of the medial collateral ligament of the elbow J Bone Joint Surg Am 1997; 79(8): 1223-31.]. Because this bundle guides the joint’s movements, Fuss called these fibres “the guiding bundle.”. Ligaments & Stability of Elbow: Primary static stabilizers . The ulnar collateral ligament of the human elbow joint. Transmission of pressures acroos the elbow joint Anat Rec 1964; 150: 243-7.]. recommended that posterior elbow dislocations should be reduced in supination [8O'Driscoll SW, Morrey BF, Korinek S, An KN. Flexion and pronation increase the contact between the radial head and capitellum. ", "Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets. 2. Assessment of elbow stability. The elbow joint consists of two types of articulations and thus allows two types of motion. In a review of simple elbow dislocation, including eight studies with a total of 342 patients, only one recurrent dislocation was mentioned [5de Haan J, Schep NW, Tuinebreijer WE, Patka P, den Hartog D. Simple elbow dislocations: a systematic review of the literature Arch Orthop Trauma Surg 2010; 130(2): 241-9.]. Golfers experience pain in the medial epicondyle from the common flexor origin. A definition of primary and secondary constraints. 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. A biomechanical analysis of axial loading J Bone Joint Surg Am 2000; 82-A(12): 1749-53. ", "Open access journals are probably one of the most important contributions to promote and diffuse science worldwide. One hand is just above the elbow joint and other hand is placed on the wrist. origin. Biomechanical study of ligaments around the elbow joint Clin Orthop Relat Res 1991; 271: 170-9.] The AMCL and LCL were taut throughout almost the entire range of flexion. The joint capsule is thickened medially and laterally to form collateral ligaments, which stabilise the flexing and extending motion of the arm. A kinematic study Acta Orthop Scand 1999; 70(1): 6-8.]. 1. When treating an isolated coronoid process fracture type I or II, early motion may be allowed, as there appears little risk of posterior subluxation. Share. 20. examined the anatomy of the AMCL in 18 osteoligamentous elbow joint specimens [27Floris S, Olsen BS, Dalstra M, Sojbjerg JO, Sneppen O. The anatomy and role of the lateral stabilizers J Bone Joint Surg Am 1997; 79(2): 225-33.]. This hinge-like joint limits the motion of the elbow to flexion and extension. Ligamentous stabilizers against posterolateral rotatory instability of the elbow J Bone Joint Surg Am 2001; 83-A(12): 1823-8. Simple dislocations are dislocations without fractures. Morrey BF, An KN, Stormont TJ. There are a collection of ligaments that connect the bones forming the elbow joint to each other, contributing to the stability of the joint. Apply valgus stress while going from flexion to extension and back. Researchers, faculty members, and students will be greatly benefited by the new journals of Bentham Science Publishers Ltd. in this category.". 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. The weakest ligament was the PMCL. The elbow is the joint connecting the upper arm to the forearm. The three joints of the elbow complex work together, to allow bending (flexion) and straightening (extension). Morrey BF, Askew LJ, Chao EY. Simulation of elbow and forearm motion, Armstrong AD, Dunning CE, Faber KJ, Duck TR, Johnson JA, King GJ. It is important that the testing apparatus is able to measure the dynamic muscular aspect of joint stability. It consists of two separate articulations: Note: The proximal radioulnar joint is found within same joint capsule of the elbow, but most resources consider it as a separate articulation. ", "Open access journals have become a fundamental tool for students, researchers, patients and the general public. Articles are of uniformly high quality and written by the world's leading authorities. The AMCL is a stronger ligament than the PMCL and acts as the major medial ligamentous joint stabiliser. The anatomy and role of the lateral stabilizers J Bone Joint Surg Am 1997; 79(2): 225-33.]. 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. [caption id="attachment_5050" align="aligncenter" width="480"], [caption id="attachment_33074" align="aligncenter" width="829"], [caption id="attachment_10458" align="alignright" width="283"]. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. Reprinted from Journal of Bone and Joint Surgery American, 1997, volume 79, 8, Biomechanical evaluation of the medial collateral ligament of the elbow, Callaway GH, Field LD, Deng XH, et al. The MCLC and LCLC were divided in four distinct groups. In five of the ten specimens, the LUCL runs from the lateral epicondyle to the crista m. supinatoris of the ulna. Reduction of a posterior elbow dislocation should be carried out with a lax LCLC and therefore with a supinated forearm. By visiting this site you agree to the foregoing terms and conditions. You can see more about how the ligaments help control shoulder stability in activities such as the baseball pitch. 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. This conjoined tendon became taut with the forearm upon supination. The elbow joint is the synovial hinge joint between the humerus in the upper arm and the radius and ulna of the forearm which allows the hand to be moved toward and away from the body. Open reduction and internal fixation of coronoid fracture type II and III in combination with LCLC repair is advisable. Beingessner DM, Dunning CE, Stacpoole RA, Johnson JA, King GJW. The clinical consequences of this literature review are described and recommendations are given for the treatment of elbow joint dislocation. The elbow is considered a complex joint, and thus the elements contributing to stability of the elbow are no less intricate. A bursa is a membranous sac filled with synovial fluid. The role of the coronoid process in elbow stability. Callaway et al. Ligamentous stabilizers against posterolateral rotatory instability of the elbow J Bone Joint Surg Am 2001; 83-A(12): 1823-8.]. It can be concluded that muscle activity is an important posterolateral stabiliser of the elbow; strengthening of these muscles might reduce symptoms of chronic posterolateral rotatory instability. Acute elbow dislocations: simple and complex Orthop Clin North Am 1999; 30(1): 63-79.]. Simulated motion revealed less variability in measurements in comparison with manual passive motion [36Dunning CE, Duck TR, King GJ, Johnson JA. The elbow is a hinge joint allowing flexion and extension. The medial collateral ligament of the elbow is not isometric: an in vitro biomechanical study Am J Sports Med 2004; 32(1): 85-90.]. Biomechanical aspects of the elbow are considered in the context of motion, function, and stability. Josefsson PO, Nilsson BE. A surgical approach to the lateral side of the elbow should protect either the LUCL or the LCL. 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. On the inside (medial side) of the elbow nearest the hip the medial collateral ligaments are important primary stabilisers that act like guy ropes to hold the ulna in place. Schneeberger and co-workers recommend coronoid reconstruction and radial head replacement with a rigid implant for the elbow in cases of coronoid process/radial head fracture [57Schneeberger AG, Sadowski MM, Jacob HA. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. 4). Group MCLC 2 was the strong oblique group (28%), with a broad fan-shaped insertion of the transverse or oblique band not only at the coronoid process but also in the anterior band. The PMCL was taut only when the elbow was in a flexed position. 3) [16Morrey BF, An KN. With the elbow in 90° of flexion, hold the distal forearm with one hand and gently stress the lateral aspect of the elbow joint with the other. The LCL and AL became confluent with the overlying supinator tendon and so the supinator tendon reinforced the LCL and AL. Joint stability can be functionally divided in static and dynamic aspects. The authors suggest that this constraint to extension may result from the constant and fixed flexion-extension axis in the external fixator tested. Maximal internal and external rotation of the ulnohumeral joint (5.3°) was observed during flexion of the elbow joint. Functional anatomy of the ligaments of the elbow Clin Orthop Relat Res 1985; 201: 84-90.]. The LUCL was found in all 26 specimens and was thin and slender. After reducing the dislocation, the elbow should be tested for valgus stability in pronation. The literature search retrieved 108 studies. Jensen SL, Olsen BS, Tyrdal S, Sojbjerg JO, Sneppen O. Elbow joint laxity after experimental radial head excision and lateral collateral ligament rupture: efficacy of prosthetic replacement and ligament repair J Shoulder Elbow Surg 2005; 14(1): 78-84. The humeroulnar and the humeroradial joints each have a ligament connecting the two bones involved at the articulation: the ulnar collateral and the radial collateral ligaments. 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. The joint capsule is a fluid filled sac that surrounds and lubricates the joint. Fig 3 – X-ray of a posterior dislocation of the elbow. The elbow joint sacrifices mobility in order to gain stability, in contrast to the glenohumeral joint. Bookmark. The tone of the surrounding muscles contributes greatly to the stability of a joint. Usually flexion is more painful as more pressure is put on the bursa. Range of motion can be measured reliably with a standard goniometer for assessing stiffness [4Armstrong AD, MacDermid JC, Chinchalkar S, Stevens RS, King GJ. The elbow is considered a complex joint, and thus the elements contributing to stability of the elbow are no less intricate. Humeral head. Chicago 1965. An extensive network of ligaments surrounding the joint capsule helps the elbow joint maintain its stability and resist mechanical stresses. A biomechanical analysis of axial loading J Bone Joint Surg Am 2000; 82-A(12): 1749-53.]. Gray H. Anatomy of the human body. This rotatory instability with the forearm in supination was reduced significantly when active flexion was simulated. If you do not agree to the foregoing terms and conditions, you should not enter this site. 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. With the elbow in valgus alignment, defined as contact between the radial head and the capitellum, the load was transferred to the ulnohumeral joint in 3% of patients [34Markolf KL, Lamey D, Yang S, Meals R, Hotchkiss R.
