CONTEXT: Surgical cuff repair is indicated in full-thickness rotator cuff tear when non-operative treatment fails. Surgical cuff repair can comprehend surgery of long head of the biceps when concomitant biceps pathology is present. However, the studies executed up to now do not have yet clearly defined if additional biceps surgery affects the shoulder functionality in patients who underwent rotator cuff repair. OBJECTIVE: The aim of this study is to verify if the concomitant biceps surgery prejudices the shoulder functionality during the short-term period in rotator cuff repair patients...

OBJECTIVES: To evaluate the diagnostic value of MR arthrography (MRA) in diagnosing instability of the LHBT in patients with rotator cuff tendon tear. MATERIALS AND METHODS: The MR arthrograms of 101 patients were retrospectively reviewed and correlated with arthroscopic findings as the standard reference. Images were evaluated for (1) the integrity of the LHBT, (2) the position of the LHBT (subluxation/dislocation on axial images, inferior displacement on oblique sagittal image) and (3) the integrity of the biceps pulley (SGHL, supraspinatus and subscapularis tendon adjacent to the rotator interval)...

The Nordic hamstring exercise (NHE) is a field-based exercise designed for knee-flexor eccentric strengthening, aimed at muscle strains prevention. However, possible effects of NHE programmes on other hamstring injury risk factors remain unclear. The purpose of this study was to investigate the effects of a NHE training programme on multiple hamstring injury risk factors. Twenty physically active young adults were allocated into two equal sized groups: control group (CG) and training group (TG). The TG was engaged in a 4-week NHE programme, twice a week, 3 sets of 6-10 repetitions; while CG received no exercise intervention...

The neural command from motor neurons to muscles - sometimes referred to as the neural drive to muscle - can be identified by decomposition of electromyographic (EMG) signals. This approach can be used for inferring the voluntary commands in neural interfaces in patients with limb amputations. This paper proposes for the first time an innovative method for fully automatic and real-time intramuscular EMG (iEMG) decomposition. The method is based on online single-pass density-based clustering and adaptive classification of bivariate features, using the concept of potential measure...

INTRODUCTION: Several studies have dealt with the issue of professional risk factors and onset of knee osteoarthritis (OA). In particular, occupational epidemiological studies have provided evidence that activities resulting in biomechanical overload may be linked with an increased risk of knee OA - also among farmers. To our knowledge, no cases of knee OA among chestnut farmers have been reported in the literature. CASE REPORT: We report the case of a 70-year-old Caucasian male who has worked for more than 50 years on a chestnut farm...

PURPOSE: Several techniques for performing a tenodesis of the long head of biceps (LHB) are described. Only few outcome studies are published. This note describes a unicortical fixation via a suture plate-comparable to a distal biceps refixation-performed arthroscopically or mini-open via standard suprapectoral approach. The aim of this study is to show the clinical outcome after 6, 12, and 24 months. MATERIALS AND METHODS: A consecutive series of 50 (35 male, 15 female) patients at the mean age of 49 years (range 23-75) who underwent tenodesis of the LHB were followed for 2 years...

BACKGROUND: Arthroscopic examination of the tendon has been described as the "gold standard" for diagnosis of tendinitis of the long head of the biceps (LHB). An arthroscopic finding of an inflamed and hyperemic LHB within the bicipital groove has been described as the "lipstick sign." Studies evaluating direct visualization in diagnosis of LHB tendinitis are lacking. METHODS: During a 1-year period, 363 arthroscopic shoulder procedures were performed, with 16 and 39 patients prospectively selected as positive cases and negative controls, respectively...

Eccentric strength training alters muscle architecture, but it is also an important factor for the prevention of hamstring injuries. The purpose was to determine the architectural adaptations of the biceps femoris long head (BFlh) after eccentric strength training with nordic hamstring exercise (NHE), followed by a subsequent detraining period. The participants in this intervention (n=23) completed a period of 13 weeks consisting of a first week of control and prior training, followed by 8 weeks of eccentric strength training with NHE, and concluding with a 4-week period of detraining...

The posterior thigh muscles on the right side of an 81-year-old male cadaver had multiple variations, denoted muscles I-IV. Muscle I originated from the posteromedial surface of the greater trochanter and divided into two muscle bellies. These muscle bellies fused with the long head of the biceps femoris and were innervated by two branches from muscular branches of the semitendinosus and the long head of the biceps. Muscle II separated from the medial surface of the long head of the biceps in the proximal third and fused with the semitendinosus in the distal fourth...

INTRODUCTION: Calcifying tendinitis of the shoulder is characterized with the formation of the calcium deposits in tendon, which mostly involves supraspinatus. The formation of the calcium deposits may be related to the excessive mechanical stimulation and non-tenocytes generation from tendon stem cell. The disease is usually associated with pain, especially when activating the shoulder. MATERIALS AND METHODS: We describe one case of calcifying tendinitis involving the long head of the biceps brachii and superior labrum...

BACKGROUND: There is no univocal consensus regarding Long Head of the Biceps (LHB) best treatment between tenotomy and tenodesis. There is no consensus regarding the best location to perform the tenodesis. The LHB tenodesis performed by the proximal tendon excision as first step can miss the proper tension to the muscle belly. Fixations proximal to the pectoralis major can lead to groove pain. This study aims to test the efficacy of a new LHB tenodesis technique by comparing its results with the tenotomy...

BACKGROUND: Arthroscopic repair of large to massive rotator cuff tears commonly retear. To improve healing rates, a number of different approaches have been utilized, including the use of grafts, which may enhance the biomechanical and biologic aspects of the repair construct. However, the outcomes after the use of grafts are diverse. PURPOSE: To systematically review the literature for large to massive rotator cuff tears to determine whether the use of grafts generally provides superior tendon healing and clinical outcomes to the repairs without grafts...
