INTRODUCTION: The stability of the glenohumeral joint (GHJ) is dependent upon passive stabilizing mechanisms such as the glenoid labrum and long head of the biceps (LHB) tendon. The labrum improves GHJ stability by increasing the glenoid concavity, and the contiguous structure of the labrum and LHB tendon may increase tension on the labrum during superior humeral translations which may contribu...

BACKGROUND The prevalence of rotator cuff tears increases with age and several studies have shown that diabetes is associated with symptomatic shoulder pathologies. Aim of our research was to evaluate the prevalence of shoulder lesions in a population of asymptomatic elderly subjects, normal and with non insulin - dependent diabetes mellitus. METHODS The study was performed on 48 subjects wit...

Ganglion cysts commonly occur around the shoulder, mostly in the spinoglenoid and suprascapular notches. We report a very rare case of intra articular Ganglion cyst of the long head of the biceps tendon that originated from the bicipital groove as a rare cause of shoulder pain.

INTRODUCTION/PURPOSE Characterization of hamstring mechanics during sprinting is fundamental to understanding musculotendon injury mechanisms. The objective of this study was to use muscle-actuated forward dynamic simulations to investigate musculotendon mechanics of the biceps femoris long head during the swing phase of sprinting. METHODS We used a three-dimensional linked segment model with...

Introduction Biceps brachii is described as a superficial muscle in the anterior compartment of the arm. It is a flexor of the elbow joint and a powerful supinator of the forearm. Standard anatomical textbooks describe the muscle as arising by two heads, a long and a short head arising from the supraglenoid tubercle and coracoid process of scapula, respectively. The two heads form a common bell...

Diagnostic ultrasound (US) is noninvasive, non-ionisating and cost-effective imaging diagnostic technique. It has emerged as a useful imaging modality for the diagnosis of joint and soft tissue pathology. The shoulder is probably the most frequently analyzed joint. Diagnostic US can be considered as an extension of physical examination and has better sensitivity and specificity for the detectio...

A unilateral four-headed pectoralis major muscle was observed on the left side of an 83 year-old Caucasian male cadaver. The accessory tendon arises from the lateral aspect of the pectoralis major muscle, travels along with the tendon of the long head of the biceps brachii and blends into the capsule of the shoulder joint. This anomaly is rare. A complete or partial absence of pectoralis major ...

Calcifying tendinitis is a common disorder related to deposition of hidroxyapatite crystals, which is most common around the shoulder joint, involving the supraespinosus tendon. It can however, affect almost any tendon at its insertion. Clinical features are variable and include pain and inflammation that often resolves spontaneously. We present a case of bilateral calcifying tendinitis of the ...
