Bicep tendon

BACKGROUND: Transfer of the anterior latissimus dorsi and teres major (LDTM) tendons has demonstrated favorable outcomes in patients with irreparable anterosuperior rotator cuff tears1 . The objective of this procedure is to restore internal rotation strength, enhance active range of motion, and provide pain relief while preserving the glenohumeral joint. DESCRIPTION: The incision extended from the coracoid to the inferior border of the pectoralis major tendon, following the deltopectoral interval located laterally to the coracoid...

INTRODUCTION: Pathologies of the shoulder, i.e. rotator cuff tears and labral injuries are very common. Most patients receive MRI examination prior to surgery. A correct assessment of pathologies is significant for a detailed patient education and planning of surgery. MATERIALS AND METHODS: Sixty-nine patients were identified, who underwent both, a standardised shoulder MRI and following arthroscopic shoulder surgery in our hospital. For this retrospective comparative study, the MRIs were pseudonymised and evaluated separately by an orthopaedic surgeon and a radiologist...

The subject-specific range of motion (RoM) of a musculoskeletal joint system is balanced by pre-tension levels of individual muscles, which affects their contraction capability. Such an inherent pre-tension or pre-stretch of muscles is not measureable with in vivo experiments. Using a 3D continuum mechanical forward simulation approach for motion analysis of the musculoskeletal system of the forearm with 3 flexor and 2 extensor muscles, we developed an optimization process to determine the muscle fibre pre-stretches for an initial arm position, which is given human dataset...

Background Arthroscopy in diagnosing a rotator cuff injury has surgical and anaesthesia-related risks. Magnetic resonance imaging (MRI), a non-invasive procedure, is expensive, and lacks dynamic components making it less favourable. Clinical examination narrows the diagnosis, but lacks diagnostic accuracy due to overlap of clinical signs and symptoms. We aimed to determine the diagnostic accuracy of clinical examination and MRI in rotator cuff tears by correlating it with arthroscopy. Methods This prospective, cross-sectional validation study included patients (N=28) with shoulder pain with clinical characteristics suggestive of rotator cuff tears...

The present case report investigates the effectiveness of a progressive physiotherapy rehabilitation program in aiding the recovery of a patient who underwent biceps tenodesis. It is a surgical procedure involving the reattachment or relocation of the biceps tendon to alleviate pain and enhance function in conditions, like tendinitis or tears. The rehabilitation program is specifically tailored to address the distinct challenges associated with biceps tenodesis recovery, focusing on gradual exercises aimed at improving strength, range of motion (ROM), and functional capacity...

The purpose of this review is to provide a comprehensive resource for shoulder proprioception assessment and its integration into clinical decision making as well as targeted rehabilitation protocols. Data for this review were acquired from peer-reviewed articles from computerized online databases, namely PubMed and Medline, published between 1906 and 2021. The development of digital/smart phone goniometers can improve shoulder joint range of motion (ROM) measurements and demonstrate comparable measurement accuracy to the universal standard goniometer...

Tendon properties impact human locomotion, influencing sports performance, and injury prevention. Hamstrings play a crucial role in sprinting, particularly the biceps femoris long head (BFlh), which is prone to frequent injuries. It remains uncertain if BFlh exhibits distinct mechanical properties compared to other hamstring muscles. This study utilized free-hand three-dimensional ultrasound to assess morphological and mechanical properties of distal hamstrings tendons in 15 men. Scans were taken in prone position, with hip and knee extended, at rest and during 20%, 40%, 60%, and 80% of maximal voluntary isometric contraction of the knee flexors...

BACKGROUND: Hamstring strain injuries are associated with significant time away from sport and high reinjury rates. Recent evidence suggests that hamstring injuries often occur during accelerative running, but investigations of hamstring mechanics have primarily examined constant speed running on a treadmill. To help fill this gap in knowledge, this study compares hamstring lengths and lengthening velocities between accelerative running and constant speed overground running. METHODS: We recorded 2 synchronized videos of 10 participants (5 female, 5 male) during 6 accelerative running trials and 6 constant speed running trials...

Tendinopathy and partial tears of the long head of the biceps tendon are a common cause of anterior shoulder pain and are often associated with many other shoulder pathologies. Multiple open and arthroscopic tenodesis techniques exist in the literature, with varying locations along the proximal humerus and a multitude of different implants. This article describes a cost-effective, implant-free, subpectoral biceps tenodesis technique that can be used as open or in conjunction with arthroscopy. Our technique differs from other tunnel techniques in its modified docking configuration into the intraosseous canal, decreasing stresses at the bone-tendon interface...

BACKGROUND: The long head of the biceps tendon (LHBT) is a well-known source of pain in the shoulder, especially in active patients. PURPOSE: To evaluate the outcomes and return-to-sports rate after all-arthroscopic suprapectoral tenodesis of the LHBT using a small knotless anchor. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: In this retrospective study, 27 patients-who underwent all-arthroscopic tenodesis of the LHBT using a 2...

BACKGROUND: To compare the histopathological results of biceps tenodesis (BT) performed with normal, low, and high pressures for superior capsule reconstruction (SCR) in rabbits with massive rotator cuff tears. MATERIALS AND METHODS: Thirty rabbits were divided into three groups. Rabbits 1-10 underwent SCR with BT at the same pressure (Group 1), value measured in the groove; 50% lower (Group 2); 50% higher (Group 3). After the 4-week follow-up, shoulder were en-bloc excised and histopathological evaluation was performed with modified Bonar's scale...

OBJECTIVES: Hamstring strain injuries (HSIs) commonly affect the proximal biceps femoris long head (BFlh) musculotendinous junction. Biomechanical modeling suggests narrow proximal BFlh aponeuroses and large muscle-to-aponeurosis width ratios increase localized tissue strains and presumably risk of HSI. This study aimed to determine if BFlh muscle and proximal aponeurosis geometry differed between limbs with and without a history of HSI. METHODS: Twenty-six recreationally active males with (n = 13) and without (n = 13) a history of unilateral HSI in the last 24 months underwent magnetic resonance imaging of both thighs...

For most shoulder surgeons, addressing massive rotator cuff tears that have retracted ends poses a significant challenge. This study introduces a technique, termed the "sandwich augmentation technique," which incorporates the long head of the biceps tendon (LHBT) into a single-row rotator cuff repair. The procedure, performed arthroscopically with the patient in the lateral decubitus position, involves attaching the LHBT and rotator cuff tissues together to the greater tuberosity. This effectively sandwiches them within the rotator cuff footprint...

PURPOSE: To evaluate the 1-year clinical outcomes of patients treated with combined proximal biceps tenodesis and repair of type II to III subscapularis tendon (SST) injuries according to Lafosse et al., using the Loop 'N' Tack (LNT) technique. METHODS: All patients undergoing proximal biceps tenodesis and rotator cuff repair between March 1, 2020, and January 30, 2022, were retrospectively identified. Only patients undergoing combined proximal biceps tenodesis and repair of grade II or III SST injuries with a minimum follow-up of 1 year were included...

BACKGROUND: Vibration of one limb affects motor performance of the contralateral limb, and this may have clinical implications for people with lateralized motor impairments through vibration-induced increase in cortical activation, descending neural drive, or spinal excitability. OBJECTIVE: The objective of this study was to evaluate the effects of acute biceps brachii tendon vibration on force steadiness and motor unit activity in the contralateral limb of persons with Parkinson's disease...

BACKGROUND: Both inlay and onlay arthroscopic biceps tenodesis (ABT) are common procedures performed during rotator cuff repair. The inlay method involves creating a bone socket in the bicipital groove to secure the long head of the biceps tendon (LHBT) using an interference screw. The onlay method utilizes a suture anchor to secure the LHBT on the surface of the bicipital groove. Little is known on the long-term differences in patient reported outcomes (PROs) between these two techniques...

Previous training studies with comprehensive stretching durations have reported that an increase in range of motion (ROM) can be related to decreases in muscle stiffness. Therefore, the purpose of this study was to analyze the association between the passive muscle stiffness of three muscle groups (triceps surae, quadriceps, hamstrings) to the respective joint ROM. Thirty-six healthy male soccer players volunteered in this study. After a standardized warm-up, the muscle stiffness was tested via shear wave elastography in six muscles (gastrocnemius medialis and lateralis, rectus femoris, semitendinosus, semimembranosus, and biceps femoris long head)...

PURPOSE: The aim of this study was to determine whether a 9-week resistance training program based on high load (HL) versus low load combined with blood flow restriction (LL-BFR) induced a similar (i) distribution of muscle hypertrophy among hamstring heads (semimembranosus, SM; semitendinosus, ST; and biceps femoris long head, BF) and (ii) magnitude of tendon hypertrophy of ST, using a parallel randomized controlled trial. METHODS: A total of 45 participants were randomly allocated to one of three groups: HL, LL-BFR, and control (CON)...

The distal rupture of the biceps brachii muscle tendon (DBT) accounts for 3% of biceps ruptures. Diagnosis typically relies on high clinical suspicion and complementary imaging studies, with >90% of cases documented in males between the fourth and sixth decades of life. Reports of DBT ruptures in females are scarce, mostly involving partial and degenerative injuries. Here, we present an unprecedented case of a 28-year-old female professional mixed martial arts athlete with a total traumatic DBT rupture. The athlete underwent surgical repair using anchor reattachment technique...
