The tendon of the subscapularis muscle attaches both to the lesser tuberosity aswell as to the greater tuberosity giving support to the long head of the biceps in the bicipital groove. Subsequent techniques attempted to more accurately restore the anatomic footprint by utilizing an anterior incision to retrieve the tendon and a posterior incision to reattach the tendon to the biceps tuberosity. J. In the three year period, 12 cases of MRI shoulder (5 MRI and 7 MR arthrograms) containing bifurcate long head of the biceps tendon were identified. Biceps muscle resection may be necessary in these injuries because of delayed presentation and associated devascularization and denervation of the displaced muscle41,46. 41 Moorman III C, Silver S, Potter H, Warren R. Proximal Rupture of the Biceps Brachii with Slingshot Displacement into the Forearm. Treatment of partial tears often begins conservatively with splinting, non-steroidal therapy, and physical therapy25.

Repair of the lacertus fibrosus has been shown to strengthen the distal biceps tendon repair, but at present there is no proof of improved clinical results following lacertus fibrosus repair38. Pain in the shoulder and biceps is the main symptom. 16 Furlani J. Electromyographic study of the m. biceps brachii in movements at the glenohumeral joint. Found inside – Page iiFulfilling the need for an easy-to-use resource on managing musculoskeletal disorders and sports injuries, this book provides differential diagnostic workups with recommended gold standard evaluations that lead to a simple and accurate ... Medial dislocation of the biceps tendon remains deep to the subscapularis and enters the glenohumeral joint. Within the bicipital groove the deeper, sliding surface of the tendon is avascular and composed of fibrocartilage2. Acad. A recent randomized clinical trial demonstrated no significant differences in outcomes between single and double incision approaches with the exception being an approximate 10% greater flexion strength in the double incision group31. A thickened and edematous LBT (arrows) is identified anterior to the humerus at a level distal to the bicipital groove outlined by surrounding mild edema. 9 Gardner E, Gray D. Prenatal development of the human shoulder and acromioclavicular joints. Fat-suppressed axial proton density-weight images at the level of the bicipital groove (left) and distal to the bicipital groove (middle) and fat-suppressed T2-weighted coronal oblique view (right) in a 51 year-old male complaining of swelling and bruising in the upper arm after feeling a pop with heavy lifting 2 weeks prior. The dislocated tendon may be seen anterior to the subscapularis tendon (20a), within an intratendinous tear of the subscapularis tendon (21a), or deep to the subscapularis tendon in an intra-articular location (22a). Seiler III, J., Parker, L., Chamberland, P., Sherbourne, G. & Carpenter, W. The distal biceps tendon: two potential mechanisms involved in its rupture: arterial supply and mechanical impingement. In addition MRI provides information that helps differentiate other entities that may simulate distal biceps injury. 18 Yamaguchi K, Riew KD, Galatz LM, Syme JA, Neviaser RJ. The bicep muscle has two tendons. Available at: http://onlinelibrary.wiley.com/doi/10.1111/j.1600-0838.2004.00421.x/full. B, Probable mechanism of injury to the biceps … Orthop. What is your diagnosis? (A, From the Sixth Plate of Muscles.Possibly by Jan Stevenz van Calcar [Flemish ca. Fat-suppressed proton density-weighted (left) and T2-weighted (right) sagittal images that include the distal biceps demonstrated the normal fanned appearance as the tendon approaches the bicipital tuberosity. A complete rupture of any tendon in the body is rare. Traumatic closed transection of the biceps brachii in the military parachutist. Schwartz ML, Al-Zahrani S, Morwessel RM, Andrews JR. Ulnar collateral ligament injury in the throwing athlete: evaluation with saline-enhanced MR arthrography. Partial tears of the distal biceps tendon typically present with a more insidious onset with the patient complaining of chronic pain, often without significant loss of strength. Anterosuperior impingement has also been proposed as a mechanism of superior subscapularis and pulley mechanism injury32. There was mild fluid in the tendon sheath around each bifid branch of the long head of the biceps tendon, which made it easier to appreciate the split. The difficulties in categorizing LHBT injuries arise because more than one type of tendon lesion may be present at the same time and in more than one tendon location, and additional shoulder pathology is common. The common … Accessory heads of the biceps brachii are common, ranging from 9.1-22.9% depending on the ethnic group, being most common in the Asian population. The lateral limb of the coracohumeral ligament (blue arrowhead) is identified covering the LHBT. (Basel). A biceps tendon injury is a tear or rupture of connective tissue that connects the biceps muscle of the upper arm to bones at either the shoulder (proximal tendon) or elbow (distal tendon). Only 3% second most common lesion encountered in shoulder MRI, patients presented with isolated rotator interval involvement observed in 77.7% (n=63) cases with involvement of without involving cuff. Care must be taken to ensure that the MR image being evaluated is the superior-most cut through the lesser tuberosity demonstrating a convex contour. Radiology. 31 Baumann B, Genning K, Böhm D. Arthroscopic prevalence of pulley lesions in 1007 consecutive patients. Arai et al demonstrated a tendinous slip that extends superiorly from the insertion of the superior-most intramuscular tendon of the subscapularis which extends deep to the LHBT and inserts into the fovea capitis of the humerus, represented by a somewhat flattened region superior to the lesser tuberosity and deep to the path of the LHBT. The features of severe tendinosis may overlap with the appearance of low-grade partial tears18. Clin. 1997;13(4):499-501. In this case there is moderate tendinosis of the long biceps tendon at the insertion characterized by ill-defined increased intrinsic tendon signal. The tendon that attaches the biceps muscle to the forearm bones (radius and ulna) is called the distal biceps tendon. A highly illustrated account of modern radiology suitable for medical students and junior doctors. Intrasubstance delamination tears appear as longitudinally oriented intratendinous increased signal on fluid-sensitive sequences. While two tendons attach the biceps muscle to the bone at the shoulder, only one tendon attaches it to the elbow. 2012;57:76-89. Axial MR images demonstrate an empty bicipital groove. The Rotator Interval and Long Head Biceps Tendon: Anatomy, Function, Pathology, and Magnetic Resonance Imaging May 2012 Magnetic resonance imaging clinics of North America 20(2):229-59, x This can be accomplished with an intact distal biceps, but with a complete distal rupture there is no cord-like structure under which the examiner’s finger may be hooked14. The biceps muscle is located in the front of your upper arm. Noted experts who have developed or perfected these techniques guide the reader in stepwise detail through each procedure. Where appropriate, the book covers both open and arthroscopic techniques for each injury or problem. In addition SLAP tears are also associated with rotator interval lesions and medial biceps pulley lesions25,26. The thinner lateral structure maintains a more vertical orientation (red arrows). Axial proton density-weighted fat-suppressed image at the upper margin of the lesser tuberosity (left) and sagittal oblique T2-weighted FSE medial to the bicipital groove at the level of the lesser tuberosity (right) images demonstrate intratendinous dislocation of the LHBT. Not surprisingly, subscapularis tears are most commonly associated with LHBT instability. 15 Gheno R, Zoner CS, Buck FM, et al. 55 year-old female with chronic shoulder pain. Found insideThis book provides a broad overview of operative and non-operative treatments of various conditions affecting the shoulder. However, a more recent technique utilizes a single anterior incision with transosseous sutures to reattach the distal biceps tendon to its normal footprint in order to maximize supination29. This is … Am. The lacertus fibrosus extends over the proximal flexor muscles and is tethered by several strong fascial adhesions before inserting at the ulnar aspect of the proximal ulna2. 34 Schaeffeler C, Waldt S, Holzapfel K, et al. 43 Carter AN, Erickson SM. Lesions within the distal bicipital groove and beyond will not be seen. 2010;18:645–656. The popliteal tendon (PT) has its proximal attachment on the lateral femoral condyle, anteroinferiorly to the lateral collateral ligament. The dislocated tendon may also be palpable. The long biceps tendon makes a sharp turn at the humeral head and continues its course in the bicipital groove (intertubercular sulcus). Kibler et al. Although x-rays cannot show soft tissues like the biceps tendon, they can be useful in ruling out other problems that can cause shoulder and elbow pain. In addition, there was a significantly greater incidence of minor, transient complications such as transient neuropraxia of the lateral cutaneous nerve with the single incision approach31. 3 In addition, these images provide good visualization of the subscapularis muscle and tendon, the humeral head, and the glenoid . A 3D graphic view of the anterior shoulder with the coracohumeral ligament (CHL) largely resected to demonstrate the close proximity of the CHL and superior glenohumeral ligament (SGHL) to the long head of the biceps tendon (LHBT) as it traverses the rotator interval. Potapov, A., Laflamme, Y. G., Gagnon, S., Canet, F. & Rouleau, D. M. Progressive osteolysis of the radius after distal biceps tendon repair with the bioabsorbable screw. With tendon rupture, distal retraction of the long head of the biceps muscle and tendon result in the characteristic “Popeye” deformity with accompanying ecchymosis, if acute. 2007;89:1001-1009. Study Design: Descriptive laboratory study. MRI plays an important role in evaluating the LHBT and in identifying significant LHBT pathology. 47 Lo IKY, Burkhart SS. Variant anatomy. Partial tears of the biceps tendon are diagnosed by abnormal intra-tendinous fluid signal and alterations in tendon caliber (Figure 13). It is attached to the bones of the shoulder and elbow by tendons — strong cords of fibrous tissue that attach muscles to bones. Abduction and internal rotation of the arm allows visualization of the subscapularis insertion and footprint47. MRI readily demonstrates the condition in the acute phase. 2008;17(1):14-20. Extra-articular structures that contribute to LHBT stability include the transverse humeral ligament, the pectoralis major muscle and tendon, and the bicipital groove. Star: Radius. Available at: http://linkinghub.elsevier.com/retrieve/pii/S1058274603002568. Biceps Tendinitis. The MRI appearance of tendinosis is made on the basis of abnormal tendon diameter or increased tendon signal intensity that does not parallel fluid (Figure 14)3. & Moss, M. Optimal positioning for MRI of the distal biceps brachii tendon: flexed abducted supinated view. At arthroscopy, the hypertrophied tendon can be seen to buckle in the joint with forward elevation of the arm with the elbow extended39. Tenotomy can be performed arthroscopically by transecting the LHBT at the superior labrum or supraglenoid tubercle, allowing the tendon to retract distally and out of the glenohumeral joint and into the bicipital groove. J. J. Arthrosc. An MRI of the right elbow was performed for greater specificity. The anomalous course is confirmed on the sagittal T2-weighted (middle left) and coronal T1-weighted images (far left). Tendon thickening, flattening, and a reduced caliber are all reliably associated with tendon degeneration. However when we look at the insertion of the brachialis … Heinzelmann, A. D., Savoie, F. H., Ramsey, J. R., Field, L. D. & Mazzocca, A. D. A combined technique for distal biceps repair using a soft tissue button and biotenodesis interference screw. Biceps tendonitis is a well recognized source of anterior shoulder pain that may be associated with subscapularis tears and subacromial impingement. Knee Surgery, Sport. The initial findings of biceps instability are subtle, depicted by only minor displacement or shift of the LHBT within the bicipital groove and may be difficult to demonstrate by imaging or arthroscopy. The superior glenohumeral ligament fuses with the CHL laterally and forms a ligament layer between the biceps tendon (BT) and the superior-most inserting subscapularis tendon (SScT) at the lesser tuberosity (LT). Surg. Found insideEffectively perform and interpret musculoskeletal ultrasound with this concise, highly illustrated resource by Jon A. Jacobson, MD. Fully revised, this bestselling title covers all the essential details of musculoskeletal ultrasound imaging ... 22 Snyder GM, Mair SD, Lattermann C. Tendinopathy of the long head of the biceps. The length of the biceps tendon sheath was measured from the superior margin of the greater tuberosity to the inferior-most collection of contrast in the biceps tendon sheath on coronal images that best depicted the anatomy.Measurements from the inferior margin of the subscapularis tendon to the inferior margin of the biceps tendon sheath were also made on the coronal images, … Shoulder Elbow Surg. Type VI: Intra-articular tendon dislocation-tear of the medial limbs of the ligaments and detachment of the subscapularis from the lesser tuberosity. The Long Head of the Biceps Tendon: Normal Anatomy and Pathology on MRI Lynne S. Steinbach, M.D. Isolated tears of the long head component are less commonly seen. Found inside – Page iiiThis quick-reference guide is the first book written specifically for the many third- and fourth-year medical students rotating on an orthopedic surgery service. Eames, M. H. A., Bain, G. I., Fogg, Q. Distal biceps rupture most commonly affects the dominant arm of men from age 40 to 60. 48 Favorito PJ, Harding WG, Heidt RS. Evidence for dissection of muscle from the ulna is seen on the sagittal STIR series posteriorly with small suture artifacts abutting the posterior lateral ulna (arrowheads). Coronal oblique T2-weighted fat-suppressed (left), sagittal oblique T2-weighted FSE (middle), and axial proton density-weighted fat-suppressed (right) images depict a severely thickened intra-articular LHBT with heterogeneous increased signal typical for an "hour-glass biceps". 1953;92:219-76. The short head component is most commonly torn19 with variable involvement of the more proximally inserting component by tendinosis, partial tear, or complete tear3. 2005;235(1):21-30. From Andreas Vesalius: De Humani Corporis Fabrica. However when we look at the insertion of the brachialis tendon on the coronoid process, there is tearing of the tendon with a lot of bone marrow edema as … Alternatively, brachialis muscle strains may be an isolated finding with an intact distal biceps (Figure 16). The sagittal T2 FSE image on the left is centered over the course of the distal biceps tendon and demonstrates intact tendon fibers (red arrows) extending to the biceps tuberosity, but the fibers are too small to represent the entire distal biceps tendon suggesting that a portion of the tendon is absent at this level (arrowheads). O’Driscoll, S. W., Goncalves, L. B. J. The usual presentation is pain over the anterior shoulder and the bicipital groove. Correlation of the SLAP lesion with lesions of the medial sheath of the biceps tendon and intra-articular subscapularis tendon. Instead, partial and complete tears of the LHBT are usually associated with underlying tendon pathology such as tendon degeneration. Type II lesions consist of superior labral fraying with stripping of the labrum undermining the attached biceps tendon. Clin. The long head of the biceps arises from the supraglenoid tubercle and the short head of the biceps arises from the coracoid process. Vardakas, D. G., Musgrave, D. S., Varitimidis, S. E., Goebel, F. & Sotereanos, D. G. Partial rupture of the distal biceps tendon. accessory head of long head of biceps tendon, long head of biceps brachii tendon pathology, medial (ulna) collateral ligament complex, lateral (radial) collateral ligament complex, accessory flexor digitorum superficialis indicis, accessory head of the flexor pollicis longus, superficial palmar branch of the radial artery, long head: supraglenoid tubercle of the scapula, bifid/bifurcated insertion: anatomic variant that arises from persistent division between the short head and long head of the distal biceps brachii tendon. The primary medial stabilizers are the medial limbs of the superior glenohumeral and coracohumeral ligaments and the subscapularis tendon. Repair of concomitant impingement, rotator cuff tears, and labral pathology is performed in conjunction with a tenodesis or tenotomy of the LHBT. & Leslie, B. M. Effectiveness of magnetic resonance imaging in detecting partial and complete distal biceps tendon rupture. Because the LHBT sheath communicates with the glenohumeral joint, fluid surrounding the LHBT in the bicipital groove may reflect tenosynovitis or fluid extension from a glenohumeral joint effusion. Med. The tendon of the long head of the biceps is innervated by a network of sensory and sympathetic fibers that are asymmetrically distributed with a higher concentration of innervating fibers at the tendon origin. Complete tears of the biceps are indicated by absence of tendon within the bicipital groove (32a). in presence of increased signal within the tendons, was the 42% (n=34), amongst other RI pathologies. No associated tear of the subscapularis tendon was identified. The biceps tendon is indicated by the red arrow and demonstrates tendinosis and partial tearing. Although x-rays cannot show soft tissues like the biceps tendon, they can be useful in ruling out other problems that can cause elbow pain. 2010;26(5):578-86. Skeletal Radiol. The muscles forming the short and long heads of the biceps stay separate until just above the elbow, where they unite and connect to the distal biceps tendon. This video shows the MRI appearance of the long head of the biceps tendon and its tenuous course through the shoulder joint. Am. 25 Walch G, Nove-Josserand L, Levigne C, Renaud E. Tears of the supraspinatus tendon associated with “hidden” lesions of the rotator interval. 1993;24:33-43. The proximal biceps tendon is part of the rotator cuff. Pathogenesis of tendinopathies: inflammation or degeneration? Surg. Magnetic … Biceps activity during shoulder motion: an electromyographic analysis. Failure of the biceps tendon in young patients is rare. The medial structure (blue arrows) follows a more typical course for the long head of the biceps tendon toward the superior glenoid and appears thickened and increased in signal at the anterior superior aspect of the glenohumeral joint (upper blue arrow). The patient responded well following debridement and the biceps repair was confirmed to be intact. MRI. The tendons of the supraspinatus, infraspinatus, teres minor, and subscapularis blend with the capsule and form the cuff, which is incomplete below. Festa, A., Mulieri, P. J., Newman, J. S., Spitz, D. J. The biceps tendon has a fibrous covering (lacertus fibrosus) that can clinically feel similar to an intact tendon even though the distal biceps tendon has … A more recent modification of the Habermeyer system incorporates 6 patterns of tendon instability which can be grouped into the categories of tendon displacement or subluxation, extra-articular dislocation, and intra-articular dislocation24: (Adapted from Resnick24) Normal: Graphic depicting the biceps pulley region from an oblique axial perspective, perpendicular to the course of the LHBT just superior and medial to the bicipital groove. Distension of the bursa by simple or complex fluid, synovial proliferation, and synovial osteochondromatosis are readily demonstrated by MRI (Figure 15). The course of the LHBT moves from a dislocated intra-articular position superiorly to an extra-articular location anterior to the intact subscapularis fibers inferiorly. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Jones, J., Feger, J. Biceps Brachii Muscle. Laterally this fold of the SGHL attaches along with the superior subscapularis tendon under the LHBT at the upper margin of the lesser tuberosity (blue line) forming a layer between the LHBT (BT) and subscapularis (SScT). Available at: http://www.sciencedirect.com/science/article/pii/S1058274605800357. Although the classification of biceps instability provides valuable information regarding pathogenesis, at present this information results in little modification of the clinical decision-making and surgical approach to treating the unstable LHBT. 1. Several classifications have been proposed for patterns of biceps instability. Available at: http://radiology.rsna.org/content/235/1/21.short. The biceps tendon dislocates anteriorly becoming located anterior to the intact subscapularis tendon. Visualization of the subscapularis tendon and its footprint on the lesser tuberosity is best performed through a posterior viewing portal. Abnormalities of the rotator interval are increasingly being recognized as causes of shoulder pain and discomfort. The retracted irregular long biceps tendon is frequently identified in this region outlined by T2 hyperintense signal. 2005;87:1580-1583. Shoulder …. Type V: Intra-articular tendon dislocation-Tears of the medial and lateral limbs of the coracohumeral and superior glenohumeral ligaments with a full-thickness tear of the subscapularis allows medial dislocation of the LHBT into the joint. 2009;37(9):1840-7. Two Neviaser Awards will be presented annually at the ASES Annual Meeting. The width of the medial border and depth of the groove both affect the risk of subluxation of the long head of the biceps tendon … …. This conjoined structure is known as the bicipital-labral complex (BLC) or biceps anchor, where the fibrous tissue of the labrum blends with the biceps tendon.

Every healthcare provider dealing with musculoskeletal imaging should have this leading book. * Continues as the first authoritative and comprehensive reference on the applications of ultrasound to the musculoskeletal system. * Uses cross ... By MRI an accessory tendon is seen as an additional hypointense structure within the biceps groove that is often flattened and can be misinterpreted as a longitudinal tear of the LHBT without carefully tracing the accessory tendon to its origin (12a)15. Sports. alongside the brachialis, brachioradialis, and coracobrachialis muscles Rest the muscle in the event of a tear. In the event of a mild bicep tear, physical therapy can help heal it and restore the range of motion to the muscle. For more severe tears, surgery might be the only option to repair it fully. Proximal biceps tendinitis (tendonitis): Repeated use of the biceps or problems in the shoulder can irritate the proximal biceps tendon. Biceps tendinosis is … 3. Rupture at the LHBT musculotendinous junction has also been seen in weightlifters and correlated with anabolic steroid use24. A rare presentation of posterior dislocation of the LHBT (23a,24a) may be seen associated with anterior glenohumeral dislocations and with fractures of the greater tuberosity. J. Arthrosc. Objective: The objective of our study was to relate alterations in biceps tendon diameter and signal on MR images to gross anatomy and histology. MRI allows evaluation of the bifurcated distal biceps tendon and is able to assist in the differentiation of a complete from partial tendon ruptures. The normal tendon is low signal on all sequences. B. MRI offers the best imaging option for detecting the varied manifestations of biceps tendon pathology and helps to evaluate the adjacent frequently injured shoulder structures. Found inside – Page iiiThis book attempts to present information in an easily read, succinct way. In particular, this book tries to unpick and explain those concepts of shoulder disorders that may be difficult to understand. 2 Ahrens PM, Boileau P.

Permanent disabilities in the displaced muscle from rupture of the long head tendon of the biceps. Accessory head of the long biceps tendon arising from the anterior capsule. This axial fat-suppressed proton density-weighted image through the bicipital groove demonstrates focally increased signal involving the superiorly-most inserting subscapularis tendon (arrowhead) with a flattened and medially subluxed long head of the biceps tendon (blue arrow). Normal and Variant Anatomy of the Elbow on Magnetic Resonance Imaging. The MRI diagnosis of a dislocated long biceps tendon is typically straightforward. Gross anatomy. MRI Clin North Am 1999, 7:51-72. The axial image confirms a small articular-sided partial thickness tear of the supraspinatus at the far anterior insertion (arrow) with an adjacent tear of the lateral limb of the coracohumeral ligament (arrowheads) allowing contrast extension into the subdeltoid bursa. Because of frequent pre-existing LHBT pathology, complete rupture may occur from relatively minor trauma. A normal tendon (arrows) demonstrates low signal on T1-weighted (left) and fat-suppressed T2-weighted (right) images. Am Fam Physician. This issue reviews the use of MR imaging to rotator cuff disease and external impingement, Internal impingement syndromes, SLAP injuries and microinstability, and glenohumeral instability. 2001;10(3):250-5. Arthrosc. Nevertheless, a persistent blind spot for the arthroscopist is the LHBT within the bicipital groove. J. Tenodesis is recommended for young (<40 year-old) physically active patients with thin arms or for those with concern for cosmesis. Repetitive mechanical stresses associated with anatomic narrowing may be seen distally within the bicipital groove. The LHBT is medially subluxed with a thinned and flattened contour and subtle intrinsic linear signal consistent with a partial tear. 5 Cheng NM, Pan W-R, Vally F, Le Roux CM, Richardson MD. ISBN:0323081770. (2008) AJR. It is in this region however, that very small tears of the superior-most subscapularis tendon insertion may be seen.
