There is currently little information on the positioning of reference electrode (RE). It is generally accepted that it must be positioned on electrically neutral tissues, such as tendons or bony prominences. The objective of this study is to analyze the characteristics of the electromyographic signal (EMG) for different positions of RE as well as at different levels of muscle contraction. Signals from the brachial biceps and triceps were recorded from 18 healthy women (BMI: 21.20 kg/m2  ± 1.72; mean age: 21...

The treatment of massive rotator cuff tears (MRCT) is challenging. Insufficient tissue quality, size, and retraction of the cuff often lead to failures of repair. Different techniques like direct repair, partial repair, and graft applications have been developed, but results are not yet predictable. In this arthroscopic technique the objective is not to reconstruct the rotator cuff as a tissue layer but to restore the biomechanical function of the rotator cable with an autograft of the long head of the biceps tendon...

PURPOSE: To assess an anterior cable reconstruction (ACR) using autologous proximal biceps tendon for large to massive rotator cuff tears. METHODS: Nine cadaveric shoulders (mean age, 58 years) were tested with a custom testing system. Range of motion, superior translation of the humeral head, and subacromial contact pressure were measured at 0°, 30°, 60°, and 90° of external rotation (ER) with 0°, 20°, and 40° of glenohumeral abduction. Five conditions were tested: intact, stage II tear (supraspinatus), stage II tear + ACR, stage III tear (supraspinatus + anterior half of infraspinatus), and stage III tear + ACR...

A 23-year-old male active duty soldier presented with a biceps femoris tendon snapping over the fibular head with flexion of the knee beyond 90°. Surgical release of anomalous anterolateral tibial and lateral fibular insertions provided relief of snapping with no other repair or reconstruction required. The soldier quickly returned to full running and active duty. Snapping biceps femoris tendon is a rare but potential cause of pain and dysfunction in the lateral knee. The possible anatomical variations and the cause of snapping must be considered when determining the operative approaches to this condition...

Background: Several procedures have been proposed to address irreparable rotator cuff (RC) tears with pseudoparalysis. One recently proposed procedure is superior capsular reconstruction (SCR) using a tensor fasciae latae (TFL) autograft. Hypothesis: SCR with a locally available long head of the biceps tendon (LHB) autograft is biomechanically equivalent to SCR using TFL autograft for preventing superior humeral migration and the development of RC arthropathy in patients with irreparable RC tears...

INTRODUCTION: There remains as of yet no consensus on the optimal treatment for total or partial distal biceps tendon repairs. As such, the purpose of this study was to assess functional outcome, the impact of complications and cost effectiveness, in patients undergoing primary distal biceps tendon repair by either cortical button (CB), transosseous suture (TO) or suture anchor (SA). HYPOTHESIS: There is no difference in functional outcome and cost effectiveness, in patients undergoing distal biceps tendon repair...

BACKGROUND: The purpose of the study was to evaluate the relationship of implant-related injuries to the adjacent anatomical structures in a newer generation straight proximal humeral nail (PHN) regarding different entry points. The proximity of the proximal lateral locking-screws of the MultiLoc proximal humeral nail (ML PHN) may cause iatrogenic tendon injuries to the lateral edge of the bicipital humeral groove (BG) as reference point for the tendon of the long head of biceps brachii (LBT) as well as the lateral insertion of the infraspinatus tendon (IST)...

Most research considering biarticular muscle function has tended to focus on the sagittal plane. Instead, the purpose of this study was to evaluate the internal/external rotation moment arms of the biarticular muscles of the knee, and then to explore their function. The FreeBody musculoskeletal model of the lower limb was used to calculate the moment arms and moments that each of the muscles of the knee exerted on the proximal tibia of 12 athletic males during vertical jumping. Biceps femoris and tensor fascia latae were external rotators of the tibia, whereas semimembranosus, semitendinosus, sartorius, gracilis, popliteus and the patellar tendon were internal rotators...

BACKGROUND: Although various surgical techniques have been used to treat irreparable rotator cuff tears (RCTs), debate remains regarding which treatment is most effective. The purpose of our study was to compare the outcomes of partial rotator cuff repair versus repair with augmentation of the tenotomized long head of the biceps tendon (LHBT). METHODS: This study included 76 patients with large to massive RCTs. Arthroscopic rotator cuff repair with LHBT augmentation was performed in 39 patients (group I), while partial repair was performed in 37 patients (group II)...

Hypermobility spectrum disorders (HSDs) are conditions associated with chronic joint pain and laxity. HSD's diagnostic approach is highly subjective, its validity is not well studied, and it does not consider many of the most commonly affected joints. Strain elastography (SEL) reflects musculoskeletal elasticity with sonographic images. The study explored the impact of HSD on musculoskeletal elasticity using SEL. A cross-sectional design compared 21 participants with HSD against 22 controls. SEL was used to assess the elasticity of the deltoid, biceps brachii, brachioradialis, rectus femoris, and gastrocnemius muscles, and the patellar and Achilles tendon...

Achilles tendon mechanics influence plantar flexion force steadiness (FS) and balance. In the upper limb, elbow flexor FS is greater in supinated and neutral forearm orientations compared to pronated, with contributions of tendon mechanics remaining unknown in position-dependent FS. This study investigated whether distal biceps brachii (BB) tendon mechanics across supinated, neutral and pronated forearm orientations influence position-dependent FS of the elbow flexors. Eleven males (23 ± 3 years) performed submaximal isometric elbow flexion tasks at low (5, 10% maximal voluntary contraction (MVC)) and high (25, 50, 75% MVC) force levels in supinated, neutral and pronated forearm orientations...

Congenital absence of the long head of the biceps (LHB) tendon is a rare variation in shoulder anatomy. The authors present a case of congenital absence of the long head of the biceps tendon associated with a large insertion of the subscapularis muscle. The patient initially presented with shoulder pain on overhead activity. Shoulder examination was negative for signs of a torn biceps tendon. MRI revealed congenital absence of the LHB tendon, a rim rent tear of the supraspinatus, and a large insertion of the subscapularis muscle...

PURPOSE: The aim of this study is to evaluate the biomechanical parameters of biceps fatigue (time to claudication during elbow flexion) and strength between the shoulder where the tenotomy has been performed and the healthy arm. The hypothesis of this study was that measuring biceps fatigue may be more useful for determining functionality after tenotomy. METHODS: 52 patients from 2 hospitals were selected to undergo biomechanical tests of healthy and pathological arms, before and 12 months after surgery...
