Aberrant origin of the long head of the biceps: a case series. The acromioclavicular joint (ACJ)is a planar diarthrodial synovial jointof the pectoral girdle. 2001;17(4):430-432. As in the test case, LHBT injuries are rarely an isolated injury and are frequently accompanied by significant shoulder pathology. The issue when pulling is that the biceps generally fatigue faster than the lats, so the lats will get a better workout if the biceps last longer. 14 Nakatani T, Tanaka S, Mizukami S. Bilateral four-headed biceps brachii muscles: The median nerve and brachial artery passing through a tunnel formed by a muscle slip from the accessory head. Damage of the supporting biceps pulley mechanism leads to LHBT instability and is most closely associated with subscapularis tendon tears. MR arthrography of rotator interval, long head of the biceps brachii, and biceps pulley of the shoulder. The hallmark of strain is a lot of edema around the myotendinous juntion because that is where the tearing takes place. N. Am. Repetitive mechanical stresses associated with anatomic narrowing may be seen distally within the bicipital groove. Axial images are best for evaluating the LHBT at the level of the bicipital groove (9a). The remaining intact fibers of the subscapularis tendon (asterisk) prevent intra-articular dislocation of the LHBT. MRI plays an important role in evaluating the LHBT and in identifying significant LHBT pathology. Axial proton density-weighted fat-suppressed images at the upper (left) and mid (right) bicipital groove demonstrate extra-articular dislocation of the LHBT(arrow) anterior to the subscapularis(SScT) which remains attached at the lesser tuberosity associated with tear of the supraspinatus extending into the coracohumeral ligament at the lateral aspect of the biceps pulley(arrowheads). In rare cases, the long head can originate from the lateral margin of the scapula and from the capsule of the shoulder joint. The intervening rotator interval ligamentous structures are less well delineated7. Case 4: minor distal biceps tendon injury. The rotator interval structures including the biceps pulley and traversing long head of the biceps tendon are best evaluated with sagittal oblique images (8a). 4 Denard PJ, Dai X, Hanypsiak BT, Burkhart SS. 10 Franco JC, Knapp TP, Mandelbaum BR.

Repair of concomitant impingement, rotator cuff tears, and labral pathology is performed in conjunction with a tenodesis or tenotomy of the LHBT. 17 Levy AS, Kelly BT, Lintner S a, Osbahr DC, Speer KP. These signal changes are often subtle and may be mimicked by partial volume averaging and magic-angle artifacts. A small tear of the superior most inserting subscapularis tendon (arrows) allows mild intratendinous subluxation of the LHBT (arrowheads). ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Some tears are partial or isolated and affect either the more proximally located long head biceps tendon or the more distally inserting short head biceps tendon 3.

Shoulder Elb. The subcoracoid bursa is located anterior to subscapularis and beneath the coracoid process and extends caudal to the conjoined tendons of coracobrachialis and short head of biceps brachii.. Fluid in the subcoracoid bursa does not normally communicate with the glenohumeral joint but may communicate with the subacromial bursa.. Distal biceps tendon injuries are far less common than injuries to the proximal biceps tendon with an incidence of approximately 1.2/100000 1,2.They typically occur in middle-aged men with a peak at around 50 years of age 1-3.. Risk factors Other authors have classified biceps lesions based on the underlying pathologic process and the status of the biceps tendon. 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). Drake R, Vogl AW, Mitchell AWM. 55 year-old female with chronic shoulder pain. Shoulder Elbow Surg. 3-5 cm of the LHBT can be pulled into the joint and inspected during arthroscopy, allowing only partial visualization of the tendon in the groove48. Bone Joint Surg. Open Orthop J. Various schemes have been proposed to classify LHBT injuries with no clearly unified classification system. J. Arthrosc. Axial proton density-weighted fat-suppressed images at the inferior bicipital groove (far left)and superior to the bicipital groove (middle left) demonstrate the LHBT within the bicipital groove (arrow) which can be followed superiorly to the anterior supraspinatus and capsular region. A case report. 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. CHURCHILL LIVINGSTONE. Res. The LHBT (arrowhead) is medially dislocated into an intrasubstance tear of the superiorly inserting subscapularis tendon (arrow). They can be also subdivided into major and minor injuries based upon whether they require surgical management or not 6: complete tear or tendon rupture (with or without rupture of the lacertus fibrosus). They typically occur in middle-aged men with a peak at around 50 years of age 1-3. (2003) ISBN:B0084AQDG8. In: Internal Derangement of Joints. J Am Acad Orthop Surg. 2007;89:1001-1009. 2.

J. MRI arthrography is better suited for directly visualizing the biceps pulley anatomy and structures of the rotator interval because of the ability to distend and displace the rotator interval structures away from the glenohumeral joint. 3. Shoulder . J. Distal biceps tendon injuries are best evaluated with ultrasound and/or MRI and coverage of the whole distal biceps tendon from the musculotendinous junction to its distal insertion at the radial tuberosity is important 2. Long term follow-up in these patients revealed decreased elbow flexion strength of 8-29% and a decrease in forearm supination strength of 21-23% with continued complaints of pain or disability51,52. 2012;20(2):229-59, x.

Initially, microscopic tears of the tendon occur, and the healing response results in disorganization of collagen fibers and an increase in ground substance. Accessory head of the biceps brachii in a 25 year-old female with work-related shoulder injury. The coronal oblique T2-weighted fat-suppressed image through the anterior humerus demonstrates a bursal sided fluid-signal discontinuity of the anterior supraspinatus tendon (arrowhead). An abnormal test indicates a distal biceps tendon injury 1,2. MRI with or without intra-articular contrast is the preferred imaging modality for evaluating the intra-articular and extra-articular LHBT and the adjacent structures of the shoulder7. Pain may occur at rest or be worse at night, and may radiate into the biceps muscle and distally into the radial aspect of the hand. Movement of biceps and triceps when arm is flexing. 44 year-old male with chronic shoulder pain. Other reported abnormalities in patients with congenital absence of the LHBT include VATER syndrome11, congenital limb abnormalities, multidirectional instability, and glenoid dysplasia with posterior instability.

The tendon is intra-articular but extrasynovial, with a surrounding synovial-lined sheath that communicates with the glenohumeral joint and extends into the bicipital groove. Transection of the long and short head muscle bellies has been reported in military parachutists resulting from forced abduction of the arm against a static line45. 51 Mariani E, Cofield R, Askew L. Rupture of the tendon of the long head of the biceps brachii surgical versus nonsurgical treatment. Br. 5. Additional studies demonstrate an increased role for the LHBT as a glenohumeral joint stabilizer in the presence of rotator cuff tears and in the presence of glenohumeral instability20,21. Available at: http://www.arthroscopyjournal.org/scripts/om.dll/serve?action=searchDB&searchDBfor=art&artType=abs&id=a0170864. Anterosuperior impingement has also been proposed as a mechanism of superior subscapularis and pulley mechanism injury32. 2020;20(81):e129-34. The long biceps tendon arises from the supraglenoid tubercle and partly from the superior glenoid labrum (7a). Sports. 2. Bone Joint Surg. The articular surfaces are lined with fibrocartilage (like the sternoclavicular joint, it is an atypical synovial joint).. Although a full-thickness tear of the subscapularis is not required for this pattern, partial articular-sided, bursal-sided, and interstitial tears may be seen. 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. It is a boat-shaped bone that is oriented obliquely with its long axis aligned from the medial portion of the distal radius proximally to the articulation of the 1 st and 2 nd metacarpals distally.. Bennett proposed 5 patterns of biceps instability33, and Habermeyer1 described 4 types of biceps pulley lesions leading to subluxation and dislocation of the LHBT. 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. The biceps tendon dislocates anteriorly becoming located anterior to the intact subscapularis tendon. 11. Distal biceps tendon injuries usually occur in a weakened tendon during eccentric loading with the elbow in flexion and full supination 1. Radiology. Greif D, Huntley S, Alidina S et al. 24 Resnick D, Kang HS, Pretterklieber M. Shoulder. AJR. On the sagittal oblique view, the subscapularis tendon tear is seen as a lack of tendon inserting at the upper margin of the lesser tuberosity(blue line). {"url":"/signup-modal-props.json?lang=us\u0026email="}, Goel A, Rasuli B, Bell D, et al. 1. 1998;11:209-212. Imaging of the biceps anchor relies primarily on coronal oblique images. Estimate an approximate systolic blood pressure. If left untreated a distal biceps tendon injury can lead to atrophy and fatty degeneration of the biceps muscle with a reduction in elbow flexion and/or forearm supination strength 1. Available at: http://journals.lww.com/corr/Abstract/1988/03000/Rupture_of_the_Tendon_of_the_Long_Head_of_the.36.aspx. An accompanying tenosynovitis representing peritendinous inflammation may be seen. The lateral limb of the coracohumeral ligament (blue arrow) is identified covering the LHBT. 2010;23(6):683-692. Nevertheless, a persistent blind spot for the arthroscopist is the LHBT within the bicipital groove. A proximal biceps tendon tear is more common. Muscle bulk: note any asymmetry in upper and lower limb muscle bulk (e.g. Moderate tendinosis at the level of the bicipital groove with frayed tissue (middle), Severe diffuse tendinosis (right). Tenosynovitis typically demonstrates a fluid distended tendon sheath that is out of proportion to the amount of fluid in the glenohumeral joint and is best depicted on axial proton density or T2-weighted sequences. The bicipital groove is empty with no biceps tendon (arrowhead). Lesions within the distal bicipital groove and beyond will not be seen. The spinoglenoid notch lies posteriorly behind the neck. Within the bicipital groove the deeper, sliding surface of the tendon is avascular and composed of fibrocartilage2. Many mammals, such as dogs, cattle, and pigs, have a fourth head, the accessory head. 2014;2(2):87-92. Type I: Tendon displacement-subscapularis tendon (SScT) tear alone. The intra-articular portion of the long biceps tendon has a flattened and slightly larger cross-sectional contour and transitions to a more rounded and smaller cross-section as it passes into the bicipital groove (9a)2. (2003) ISBN: 9780729537520 -. The CHL and SGHL join with fibers from the subscapularis tendon (SScT) and supraspinatus tendon (SST) to form the biceps pulley, stabilizing the LHBT as it enters the bicipital groove where it continues deep to the transverse humeral ligament (THL). Heers G, Gtz J, Schubert T et al. The scaphoid is the largest of the proximal row of carpal bones and sits on the radial side of the lunate. 1. A complete rupture of the LHBT is commonly accompanied by a Popeye deformity, a characteristic bulge over the anterior lateral aspect of the proximal arm that results from distal retraction of the LHB tendon and muscle. Clin. A rim rent tear of the rotator cuff, also known as partial articular surface tendon avulsion (PASTA), is a specific subtype of partial-thickness rotator cuff tear that involves the articular surface footprint at the site of tendon attachment into the greater tubercle 2.Such small tears can extend along the tendon fibers, causing tendon delamination, which corresponds to The LHBT is 5-6 mm in diameter and approximately 10 cm in length with the musculotendinous junction found deep to the pectoralis major tendon4. 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". 2018;47(4):519-32.

J Bone Joint Surg Am. Richard L. Angelo, James Esch, Richard K. N. Ryu. Kim SJ, Kim JS, Kim HJ, Yu HW. Kibler et al. Treatment options include non-operative, conservative or surgical management with distal biceps tendon repair or reconstruction. Surgical treatment is necessary for patients with LHBT pathology that remain symptomatic after nonoperative therapeutic measures. Normal LHBT (left). Though a similarly named muscle, the triceps surae, is found on the lower leg, the triceps brachii is commonly called the triceps. 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. 2001;17(8):864-868. 1999;27(6):95-101. J. Med. fluid in the axillary pouch and posterior recess. Sequential axial images help confirm the structure as the LHBT, and utilizing the orthogonal sagittal oblique or coronal oblique views, the descending portion of the displaced LHBT can frequently be identified.

It originates directly from the superior labrum adjacent to the bicipital labral complex and inserts onto the articular surface of the subscapularis tendon. Am. J. 1995;4(6):436-440. 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. 1953;92:219-76. A fibrocartilaginous wedge-shaped articular disc,measuring between 1.5-4.0 mm 8, separates the two articular surfaces, but its function is unknown 2,6. Check for errors and try again.

The long head of the biceps femoris is a weaker knee flexor when the hip is extended (because of active insufficiency). Scand. The Long head of the biceps tendon (LHBT) arising near the SGHL at the supraglenoid tubercle and superior labrum and curves anterolaterally over the humeral head (HH) to the bicipital groove. Subluxation and dislocation of the LHBT occur with damage to the biceps pulley, and are most commonly associated with tears of the subscapularis and supraspinatus tendons. Radiology. 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. 10. 2004;13(3):249-257. Historically, the plural form of triceps was tricipites, a form not in general use today; instead, triceps is both singular and plural (i.e., when referring to both arms). The lateral radiograph of the elbow might show abnormal soft tissue shadowing with Popeye deformity 3. Case Connect. Type II lesions consist of superior labral fraying with stripping of the labrum undermining the attached biceps tendon. J. Tendon thickening, flattening, and a reduced caliber are all reliably associated with tendon degeneration. A dramatic presentation of displacement of the proximal biceps muscle has been reported in wakeboarders when a slackened towrope suddenly becomes taut while being gripped with flexed elbows. MR arthrography of rotator interval, long head of the biceps brachii, and biceps pulley of the shoulder. 1997;25 (2): 112-7. 28 Arai R, Sugaya H, Mochizuki T, Nimura A, Moriishi J, Akita K. Subscapularis tendon tear: an anatomic and clinical investigation. Ultrasound Classification of Traumatic Distal Biceps Brachii Tendon Injuries. It has been suggested that the long head fascicle is employed when sustained force generation is demanded, or when there is a need for a synergistic control of the shoulder and elbow or both. 9. The scapula is surrounded by an arterial anastomosis, the scapular anastomosis which aims to ensure an adequate supply of blood to the upper limb, but has the added benefit of adequate supply to the bone itself. Skeletal Radiol. The " neutral " grip is just somewhere in between. Interruption and irregularity of the superior glenohumeral ligament, coracohumeral ligament and subtle alterations in the position of the LHBT on sagittal images are helpful in identifying subtle biceps pulley tears (26a). 6.
