Recent studies suggest region-specific metabolic activity in hamstring muscles during injury prevention exercises, but the neural representation of this phenomenon is unknown. The aim of this study was to examine whether regional differences are evident in the activity of biceps femoris long head (BFlh) and semitendinosus (ST) muscles during two common injury prevention exercises. Twelve male participants without a history of hamstring injury performed the Nordic hamstring exercise (NHE) and stiff-leg deadlift (SDL) while BFlh and ST activity were recorded with high-density electromyography (HD-EMG)...

BACKGROUND: The ultrastructural alterations related to tendinopathy have not been well described. Most studies on this subject have been conducted many years ago and focused on material from the Achilles tendon. It was demonstrated that various comorbidities can affect ultrastructural alterations in the advanced tendinopathy, however there is very little data on ultrastructural morphology in tendinopathies related to mechanical overload as in case of the long head of the biceps brachii tendon (LHBT)...

Strength training is a valuable component of hamstring strain injury prevention programmes; however, in recent years a significant body of work has emerged to suggest that the acute responses and chronic adaptations to training with different exercises are heterogeneous. Unfortunately, these research findings do not appear to have uniformly influenced clinical guidelines for exercise selection in hamstring injury prevention or rehabilitation programmes. The purpose of this review was to provide the practitioner with an evidence-base from which to prescribe strengthening exercises to mitigate the risk of hamstring injury...

BACKGROUND: Long head biceps tendon pathology is a common cause of anterior shoulder pain and is often associated with other shoulder conditions, such as rotator cuff tears and osteoarthritis. It is well accepted that older patients are at increased risk for major and minor peri- and postoperative complications. The purpose of this study is to investigate patients over 65 years old who underwent subpectoral biceps tenodesis and compare the complication rates of this group to those of patients younger than 65 years old...

INTRODUCTION: The purpose of this study was to investigate donor site morbidity after reconstruction of defects in the head and neck region with an anterolateral thigh (ALT) flap. METHODS: From 07/2006 to 12/2015 the anterolateral thigh flap was used for reconstruction of large intra- or extraoral defects in 138 patients. The donor sites were available to examine for morbidity in 51 patients (36.7%). All patients completed a standardized questionnaire, received a physical examination, and underwent isokinetic muscle exercises of the lower extremity with a Dynamometer...

We report a case of a 15-year-old boy with chronic intermittent left shoulder pain due to an undiagnosed lesser tuberosity avulsion fracture, an associated biceps pulley injury and intra-articular dislocation of the long head of the biceps tendon. Lesser tuberosity avulsion fractures are rare injuries that are difficult to detect on clinical exam and radiographically, which may lead to delayed diagnosis and chronic shoulder instability. Few reports describe dislocations or subluxations of the biceps tendon in association with lesser tuberosity avulsions in children...

The shoulder can humble you. It is often challenging in determining the extent of pathology even when there is an adequate magnetic resonance imaging performed preoperatively and even during the so-called diagnostic portion of the arthroscopy. Abnormalities of the long head of the biceps tendon and the rotator cuff especially the subscapularis can be difficult to diagnose definitively. Experience can be very helpful in predicting pathology based on patterns seen before and knowing certain pearls that can make diagnosis and ultimately treatment more accurate...

The long head of the biceps tendon can be a significant pain generator in the setting of rotator cuff tearing. Surgeons who encounter long head of biceps tendon pathology at the time of rotator cuff repair can be confident in a high likelihood of statistically significant clinical improvement with concomitant long head of biceps surgery. Patients can be reliably counseled preoperatively that if they have both clinically apparent long head of biceps tendon pathology and rotator cuff tearing, and if they undergo long head of biceps tendon surgery with rotator cuff repair, they can expect comparable or better outcomes than isolated rotator cuff repair...

OBJECTIVE: We designed this study using super-selective intraoperative cervical nerve root stimulation aiming to support decision making about complete or partial contralateral C7 (cC7) nerve root transfer in patients with multiple cervical root avulsion injury. METHODS: Super-selective intraoperative stimulations of anterior, lateral, medial and posterior aspect of C5-C8 nerve roots were performed. Compound muscle action potentials (CMAP) were recorded in the lateral part of the deltoid (DM), long head of biceps brachii (BCM), brachioradial (BRM), long head of triceps brachii (TCM), and extensor digitorum communis (EDC) muscle...

Superior labral anterior and posterior lesions and long head biceps injury are 2 common sources of shoulder pain. The presenting complaints and physical examination findings for these etiologies are often nonspecific, making diagnosis challenging. Further complicating their diagnoses, these 2 pathologies often cooccur together or with other shoulder pathologies such as subacromial bursitis, rotator cuff tear, and shoulder instability. However, with advancement in magnetic resonance imaging and shoulder arthroscopy techniques the ability to diagnose and treat these pathologies has vastly improved over the past 30 years...

BACKGROUND: Tendinopathy of the long head of the biceps brachii tendon is one of the most common, painful conditions of the anterior part of the shoulder and often coexists with rotator cuff tears. Multifactorial etiopathology of tendinopathy is poorly understood, however, several studies indicated that it is seen predominantly in areas with decreased vascularity of the tissue; the pathology is also characterized by expansive and abundant neovascular in-growth. The aim of the study was to investigate the relationship between the neovascularization of proximal part of the long head of the biceps brachii tendon and pain along the bicipital groove...

X Clement, F Baldairon, P Clavert, J-F Kempf
INTRODUCTION: Treatment of long head of the biceps lesions is controversial. A new technique of self-locking "T" tenotomy was developed in our department in 2013. HYPOTHESIS: The main objective of the present study was to assess onset of Popeye sign after "T" tenotomy, with comparison to long head of the biceps tenodesis. MATERIAL AND METHODS: A continuous retrospective study included 180 patients with long head of the biceps lesion, either isolated or associated with rotator cuff tear...

INTRODUCTION: The Cunningham technique has been shown to be an effective and simple method to reduce a dislocated shoulder. It is based on the theory that the humeral head remains outside the glenoid fossa due to tension in the long biceps tendon. In the beginning of 2013 doctors at the emergency department in Landspitali University Hospital (LUH) in Reykjavik were instructed in the Cunningham method for reduction of anterior dislocation without sedation. The goal of this retrospective study was to evaluate the impact of its induction with regards to number of attempts, successful relocations, sedation, use of analgesics and length of stay in the ED...

INTRODUCTION: "Fosbury flop" tear is an avulsion of the posterosuperior rotator cuff from the bone with reversal healing on its medial bursal-side. This case report describes a unique variant of Fosbury flop tear with a lesion of the musculotendinous junction that healed, for its tendon part, on the anterior humerus and coracoid process. CASE PRESENTATION: A 62-year-old man developed a posttraumatic painful shoulder with active loss of range of motion. Magnetic resonance arthrography demonstrated a lesion of the musculotendinous junction of the supraspinatus with healing of the tendon on the above-mentioned structures (reverse Fosbury flop)...

OBJECTIVES: Biceps femoris long-head architectural assessment using ultrasonography (US) has not been previously described in detail for both acquisition (image capture) and digitization (image measurement) processes, and the effect of the US window width is unknown. This study aimed to describe the reliability and test-retest minimum detectable difference of US-based biceps femoris architectural measurements. METHODS: Muscle length was determined by marking the muscle-tendon junction distances...

BACKGROUND: Waterpolo consists of a combination of swimming and throwing with close contact between players. The shoulder is the most frequently injured joint, with a combination of rotator cuff tear and tendinopathy, long head biceps tendinopathy, superior labral lesions and shoulder impingement. This unique combination is a challenge for the clinician who must determine which of these shoulder pathologies is responsible for the onset of pain and the best strategy to rehabilitate the joint and prevent recurrence...

PURPOSE: The purpose of this meta-analysis was to assess whether there were differences in the outcomes between tenotomy and tenodesis in treating LHBT lesions combined with rotator cuff repairs. METHODS: Using Medline, Embase, and Cochrane, we searched for articles comparing tenotomy and tenodesis combined with rotator cuff repair which were published before April 2016 with the terms "biceps", "tenotomy", "tenodesis", and "rotator cuff". The controlled clinical studies that met the inclusion and exclusion criteria were assessed for quality of methodology by utilizing the Coleman score...

Tenodesis of the long head of the biceps (LHB) tendon has long been recognized as a valid alternative to address pathologic conditions of this tendon. However, the location and type of fixation is still a matter of discussion, because common complications associated with this procedure include failure of the repair, persistent pain, reaction to the fixation device, cosmetic deformity, and fracture. The authors describe a method of subpectoral LHB tenodesis that aims to preserve bone stock and allows a strong, easy, and reproducible type of fixation with a minimal approach...
