INTRODUCTION: In general, the long head of the biceps brachii (LHB) tendon arises from the supraglenoid tubercle in the shoulder joint, and it has an important stabilizing mechanism for the humeral head in the shoulder joint. This case demonstrates that even if the LHB tendon can be palpated outside of the shoulder joint, it may disappear in the intertubercular sulcus (IS) and in the glenohumeral (GH) joint because of abnormal articulation. PATIENT CONCERNS: This case involved the cadaver of an 82-year-old Japanese man (number 1936, cause of death: hepatocellular tumor), who was selected from the bodies used for gross anatomy practice at the Tokai University School of Medicine in 2017...

AIM: To investigate strain (SE) and shear wave elastography (SWE) characteristics of the long head of the biceps tendon (LHBT) tendinosis in comparison with magnetic resonance imaging (MRI) findings. MATERIAL AND METHODS: Twenty patients with a MRI diagnosis of tendinosis and twenty healthy subjects with normal LHBT in MRI were prospectively examined by SE and SWE. SE color mapping was divided into four types in accordance with elasticity designs: type I predominantly blue (hardest tissue), type II predominantly blue-green (hard tissue), type III predominantly green (intermediate tissue), type IV predominantly green-yellow-red (soft tissue)...

The anatomical variations of the proximal portion of the long head of the biceps brachii tendon (LHBT) are rarely observed in clinical practice. However, an increase in the rate of shoulder arthroscopic surgery has led to an increase in the observation of anatomical variations of this region. The aim of this work was to analyze the development of the LHBT in 23 human embryos ranging from the 6th to 8th weeks of development. The LHBT develops from the glenohumeral interzonal mesenchyme in the 6th week. By week 7, the myotendinous junction of the LHBT develops...

Sonography of the shoulder is widely used to assess various disorders, including tendinous diseases of the rotator cuff and the long head of the biceps brachii muscle. The shoulder is commonly explored through anterior, superior, and posterior approaches, but the inferior axillary approach is rarely considered in the literature. However, this technique allows the direct visualization of relevant anatomic structures. The aim of this pictorial essay is, first, to technically describe this approach and the normal musculoskeletal sonographic anatomy of the region and, second, to present the sonographic findings of shoulder disorders that may be helpfully explored this technique...

BACKGROUND: In the glenohumeral joint, the long head of biceps brachii (LHBB) is exposed to tension and compression loading. The short head of biceps brachii (SHBB) works only in tension. It is known that tendon under compression might develop fibrocartilaginous metaplasia that improves the resistance to compression but reduces the resistance to tension. This study evaluated the presence of cartilage in LHBB and SHBB samples, supporting its possible role in tendon tear. METHODS: Between 2014 and 2016, 13 samples of LHBB and SHBB were collected during surgery for shoulder instability, glenohumeral arthritis, and massive rotator cuff tears...

Superior capsular reconstruction (SCR) demonstrated its efficacy as a treatment option available in patients affected with irreparable posterosuperior rotator cuff tears without any signs of arthritis. Originally, the fascia lata autograft was fixed medially to the glenoid (with two or more anchors) and laterally to the greater tuberosity (with a compression double-row technique using four anchors or three transosseous tunnels). Additionally, side-to-side sutures were used to anteriorly and posteriorly connect the graft to the native residual rotator cuff tissue...

BACKGROUND: A rare form of rotator cuff tear (RCT) is observed secondary to glenohumeral dislocation, followed by immediate repositioning, as well as formation of scar tissue between tendons and tuberosities. Radiographic diagnosis of such "degloving" tears is problematic because they are obscured by scar tissue. We aimed to describe characteristics of degloving tears and report outcomes following their arthroscopic repair. METHODS: Among 67 patients who underwent arthroscopic repair of RCTs secondary to shoulder dislocation, we identified 8 patients (12%) (7 anterior dislocations and 1 posterior dislocation), aged 54...

Large to massive rotator cuff tears are challenging to repair, although there are several options for dealing with them. Among them, superior capsular reconstruction was recently introduced as an effective procedure for retaining the static stability of the shoulder joint and preventing the progression to cuff tear arthropathy. The purpose of this technique-based article is to describe a surgical option, called arthroscopic in situ superior capsular reconstruction, for large to massive rotator cuff tears using the long head of the biceps tendon...

Anterosuperior rotator cuff tears involve the subscapularis tendon, supraspinatus tendon, and rotator interval. The long head of the biceps is usually affected and unstable in these complex lesions. Arthroscopic repair of anterosuperior rotator cuff tears often consists of 2 different procedures. Whereas the subscapularis tendon is reconstructed under intra-articular visualization, the supraspinatus tendon is reconstructed under extra-articular visualization. The rotator interval is often sacrificed to improve visualization and instrumentation...

Philippe Collin, Alexandre Lädermann
Anteroinferior glenohumeral instability can be treated by variants of the Bankart repair, remplissage , and the Latarjet procedure, although all options remain associated with complications, including recurrence, stiffness, persistent pain, apprehension, and dislocation arthropathy. The authors therefore thought of a concept of dynamic anterior stabilization to treat anteroinferior glenohumeral instability by transferring the long head of the biceps within a subscapularis split to the anterior glenoid margin, thereby creating a "sling effect" by using a conservative technique...

BACKGROUND: Biceps tenodesis reduces the incidence of Popeye deformity occurring with tenotomy, but pain may occur with tenodesis superior to or within the bicipital groove. Arthroscopic suprapectoral tenodesis is an attractive alternative. The purpose of this study was to establish landmarks for arthroscopic suprapectoral tenodesis and determine the appropriate fixation point to optimize muscle tension. METHODS: Twelve fresh cadaveric shoulders were dissected. Urethane polymer was injected into the axillary artery...

We sought to identify changes in individual muscle hardness after a full marathon and to track time-dependent changes using ultrasound strain elastography (SE). Twenty-one collegiate marathon runners were recruited. Muscle hardness (i.e., strain ratio, SR) was measured using SE for the rectus femoris (RF), vastus lateralis (VL), biceps femoris long head (BF), tibialis anterior (TA), gastrocnemius medial head (GM), and soleus (SOL) muscles at the following time points: pre (PRE), immediately post (POST), day-1 (D1), day-3 (D3), and day-8 (D8), after a full marathon...

BACKGROUND: The prevalence and severity of concomitant rotator cuff pathology in the setting of proximal biceps tendon ruptures are poorly understood. Concomitant rotator cuff disease may have important implications in the prognosis and natural history of this shoulder condition. Therefore, an observational cohort of patients with an acute rupture of the long head of the biceps tendon (LHBT) was evaluated to determine the prevalence and severity of concomitant rotator cuff disease. METHODS: Thirty consecutive patients diagnosed with acute proximal biceps tendon rupture were prospectively enrolled...
