BACKGROUND: This study investigated the morphologic changes in the biceps tendon using ultrasonography before and after successful arthroscopic posterosuperior rotator cuff repair. METHODS: Forty-four patients (44 shoulders) underwent arthroscopic posterosuperior rotator cuff repair with 1-year postoperative magnetic resonance imaging (MRI) follow-up. The patients comprised 22 men and 22 women with an average age of 61 years. The cross-sectional area (CSA) of the biceps tendon in the bicipital groove was measured, and the vascularity in the bicipital groove was graded as 0 to 3, based on the signal density of the anterior circumflex artery, using power Doppler ultrasonography...

OBJECTIVES: To investigate outcomes after surgical repair of distal biceps tendon rupture and the influence of arm dominance on isokinetic flexion and supination results. BACKGROUND/PURPOSE: While relatively uncommon, rupture of the distal biceps tendon can result in significant strength deficits, for which surgical repair is recommended. The purpose of this study was to assess patient reported functional outcomes and muscle performance following surgery. METHODS: A sample of 23 participants (22 males, 1 female), who had previously undergone surgical repair of the distal biceps tendon, were re-examined at a minimum of one year after surgery...

BACKGROUND: Repair of distal biceps tendon ruptures has become widely accepted. Unfortunately, care of retracted-degenerated injuries remains a challenge for orthopedic surgeons. Complication rates appear to increase when surgery is performed in chronic cases compared to those operated acutely. Multiple techniques for chronic reconstruction with the use of grafts have been described. Recently Morrey, from the Mayo Clinic, proposed a direct anatomic repair of retracted distal biceps tendon ruptures in extreme flexion (60°-90°) to avoid grafting...

REVIEW
Jared R Thomas, Jeffrey Nathan Lawton
Although rare, biceps and triceps tendon ruptures constitute significant injuries that can lead to profound disability if left untreated, especially in the athletic population. Biceps rupture is more common than triceps rupture, with both resulting from a forceful eccentric load. Surgical repair is the treatment method of choice for tendinous ruptures in athletes. Nonoperative management is rarely indicated in this population and is typically reserved for individuals with partial ruptures that quickly regain strength and function...

OBJECTIVES: To determine whether detection of the detour sign via magnetic resonance imaging (MRI) indicates of subluxation of the long head of the biceps tendon (SLBT) in the shoulder joint and to investigate the association of SLBT with the degeneration of the long head of the biceps tendon (LBT) and rotator cuff tears. METHODS: This retrospective study included 65 patients with shoulder pain who underwent shoulder MRI and arthroscopic surgery. When axial images revealed that the LBT was displaced over the inner rim of the bicipital groove with some remaining contact with the groove (criterion 1), or demonstrated a "detour sign" of the biceps tendon (criterion 2), the lesion was diagnosed an SLBT...

BACKGROUND: Pathologic conditions of the long biceps tendon can be found within treatment of proximal humeral fractures or as a source of pain after surgery. However, simultaneous surgical treatment at the index surgical intervention is so far not well established. The purpose of this study is to evaluate the results of a simultaneous biceps treatment during plate osteosynthesis of proximal humeral fractures. MATERIALS AND METHODS: Twenty-seven patients were included into this study...

PURPOSE: The purpose of this study was to analyse the relationship between long head of the biceps brachii (LHBT) lesions and subscapularis tears. The hypothesis was that a bicipital pulley might remain intact, even in the case of a subscapularis tear. METHODS: Between 2010 and 2011, all patients who had a primary arthroscopic repair of a subscapularis tear were potentially included in this prospective study. The outcome of interest was the prevalence and type of arthroscopic lesions of the LHBT and bicipital pulley...

This study examines the electromyogram (EMG) - torque relation for chronic stroke survivors using a novel EMG complexity representation. Ten stroke subjects performed a series of submaximal isometric elbow flexion tasks using their affected and contralateral arms, respectively, while a 20-channel linear electrode array was used to record surface EMG from the biceps brachii muscles. The sample entropy (SampEn) of surface EMG signals was calculated with both global and local tolerance schemes. A regression analysis was performed between SampEn of each channel's surface EMG and elbow flexion torque...

By following the common definition of forward-dynamics simulations, i.e. predicting movement based on (neural) muscle activity, this work describes, for the first time, a forward-dynamics simulation framework of a musculoskeletal system, in which all components are represented as continuous, three-dimensional, volumetric objects. Within this framework, the mechanical behaviour of the entire muscle-tendon complex is modelled as a nonlinear hyperelastic material undergoing finite deformations. The feasibility and the full potential of the proposed forward-dynamics simulation framework is demonstrated on a two-muscle, three-dimensional, continuum-mechanical model of the upper limb...

BACKGROUND: Limited research suggests elite athletes may differ from non-athletes in clinical tendon tap reflex responses. METHODS: In this matched cohort study, 25 elite rugby league athletes were compared with 29 non-athletes to examine differences in tendon reflex responses. Relationships between reflex responses and lengths of players' careers were also examined. Biceps, triceps, patellar and Achilles tendon reflexes were clinically assessed. RESULTS: Right and left reflexes were well correlated for each tendon (rS = 0...

Rotator cuff injury (RCI) is a major musculoskeletal disorder in the adult population where inflammation and pain are major contributing factors. Coincidence of other clinical conditions like glenohumeral arthritis aggravates inflammation and delays the healing response. The mechanism and signaling factors underlying the sustenance of inflammation in the rotator cuff joint are largely unknown. The present article aims to elucidate the involvement of inflammatory molecule, TREM-1 (Triggering Receptors Expressed on Myeloid cells-1), and danger-associated molecular patterns (DAMPs), including high mobility group protein 1 (HMGB-1) and RAGE (receptor for advanced glycation end products), in the setting of RCI with respect to the severity of glenohumeral arthritis...

INTRODUCTION: Clinically, subcoracoid impingement is characterized by pain at the anterior aspect of the shoulder that is induced by adduction, internal rotation and forward flexion. This position leads to narrowing of the Coraco-Humeral Interval (CHI)-that is, the space between the coracoid process and the lesser tuberosity of the humerus. Structures in the rotator interval are at greatest risk for impingement which includes the Subscorapularis tendon, tendon of the long head of the biceps, and the middle gleno-humeral ligament...

PURPOSE: To report the clinical and radiological outcomes of arthroscopic suture bridge repair for the GT fractures of the shoulder joint. METHODS: From March 2008 to July 2013, we performed arthroscopic suture bridge repair of the GT fractures displaced more than 5 mm superiorly or posteriorly, but less than 2 cm in 40 cases [20 men, 20 women; mean age, 56 (27-80) years] with the average 32 (24-48) months follow-up. At the final follow-up, clinical (ASES, UCLA, SST, KSS score and range of motions) and radiological outcomes using post-operative MRI or CT scan were evaluated...

BACKGROUND: Anatomic reinsertion of the distal biceps is critical for restoring flexion and supination strength. Single- and double-incision surgical techniques have been reported, analyzing complications and outcomes measures. Which technique results in superior clinical outcomes and the lowest associated complications remains unclear. HYPOTHESIS: We hypothesized that rerupture rates would be similar between the 2 techniques, while nerve complications would be higher for the single-incision technique and heterotopic ossification would be more frequent with the double-incision technique...

: The subscapularis (SSC) muscle is the most powerful of the rotator cuff muscles, and plays an important role in shoulder motion and stabilization. SSC tendon tear is quite uncommon, compared to the supraspinatus (SSP) tendon, and, most of the time, part of a large rupture of the rotator cuff. Various complementary imaging techniques can be used to obtain an accurate diagnosis of SSC tendon lesions, as well as their extension and muscular impact. Pre-operative diagnosis by imaging is a key issue, since a lesion of the SSC tendon impacts on treatment, surgical approach, and post-operative functional prognosis of rotator cuff injuries...

REVIEW
Deepak N Bhatia
Distal biceps tendon (DBT) ruptures are infrequent injuries that result in pain, weakness, and cosmetic deformity. Severe retraction of the ruptured DBT can occur at the time of injury, or in chronic neglected ruptures, and surgical exposure is performed using a single incision or a 2-incision technique. The technique presented here describes an endoscopic approach using 3 portals that provide access to the retracted DBT, biceps sheath, and radial tuberosity. Preoperative sonographic localization of the retracted DBT and neurovascular structures is used to guide portal placement...
