Because pitch counts do not exist for softball, pitchers may throw between 1200 and 1500 pitches over 3-day tournaments. With this workload, a common symptom among softball pitchers is anterior shoulder pain. The purpose of this study was to examine long-head biceps tendon (LHBT) changes in youth softball pitchers following an acute bout of pitching. Nineteen softball pitchers (11.89±1.2 years; 158.23±9.71 cm; 61.59±14.76 kg) participated. Images of the LHBT were obtained prior to and immediately following a simulated game protocol...

We present a case of a post-surgical complete dislocation after excessive proximal humeral shortening osteotomy performed in a patient operated on for atrophic non-union of a proximal humeral fracture. This complication has not been previously reported. The dislocation occurred due to extensive laxity of the soft tissue envelope, predominantly the deltoid muscle, as well as rotator cuff tear. The reconstructive procedurę consisted of vertical duplication of the capsule, reinforcement of the repair with coracoacromial ligament, tenodesis of the long head of the biceps tendon to the conjoined tendon and distal transfer of the deltoid muscle...

INTRODUCTION: Examination of the mechanical behavior of the hamstrings when acting as antagonists provides information about loading of this muscle group and its role for joint stability during forceful quadriceps contractions. The aim of this study was to quantify biceps femoris long head fascicle length (FL), angle of pennation (PA) and distal tendon/aponeurosis strain during maximum voluntary contraction efforts of the knee extensors using real-time ultrasound. METHODS: Fourteen participants performed passive joint movements and maximum voluntary knee extension and flexion efforts of the knee flexors at 0°, 45° and 90° of knee flexion...

The purpose of this study was to investigate the influence of exercise order on volume load (VL) and myoelectric activation (EMG) during the bench press (BP), military press (MP) and close-grip bench press (CGBP) exercises executed with a barbell and Smith machine. Twelve men experienced in resistance training performed four different exercise sessions in randomised order. Each session consisted of four sets of a given exercise order: O1 = CGBP + MP + BP with barbell; O2 = inverse O1 with barbell, O3 = same O1 with Smith Machine; O4 = same O2 with Smith machine...

Purpose. Pathologies of the long head of the biceps tendon (LHBT) are frequently recognized in cases of rotator cuff tear. Recommendations for managing such pathologies remain debatable, and distal migration of tenotomized biceps is always a concern when only tenotomy is performed. Methods. Seventy patients of mean age 60.4 ± 6.9 years (range: 44 to 82 years) were included in this retrospective study. During subpectoral tenodesis in rotator cuff repair, pullout tensions were measured using a digital tensiometer...

Tendonosis is characterized by an increase in collagen type III relative to collagen type I, but the precise ratio of collagen type I to collagen type III in pathologic shoulder tendons has not been reported. A tendon continuously bathed in an OA synovial environment may exhibit histomorphologic differences as compared to those from shoulders with a preserved articular surface. The purpose of this study was to evaluate the biochemical and histological differences in the proximal portion of the long head of the biceps tendon (LHBT) from a non-arthritic versus an arthritic glenohumeral joint...

PURPOSE: This study aimed to assess muscle coactivation in quadriceps and hamstring muscles using ultrasound shear wave elastography. METHODS: During maximal voluntary isometric contractions (MVC), both myoelectrical activity and shear modulus of antagonist muscles were measured (i.e., rectus femoris, vastus lateralis and vastus medialis during knee flexions and semitendinosus, semimembranosus and biceps femoris long head during knee extensions). To account for changes induced by inevitable joint rotation during MVC, the shear modulus values were compared to those measured at the same knee angle during a passive cycle...

BACKGROUND: No consensus exists about the management of massive and symptomatic rotator cuff tears (RCTs). The objective of this study was to compare the 12-month clinical outcomes of various treatment options for massive RCTs. HYPOTHESIS: Arthroscopic surgery has a role to play in the treatment of massive and apparently irreparable RCTs. MATERIAL AND METHODS: A prospective multicentre non-randomised study was performed in patients with massive RCTs managed non-operatively (NONOP) or by arthroscopic tenotomy/tenodesis of the long head of biceps (aTLB), arthroscopic partial tendon repair (aPTR), arthroscopic latissimus dorsi transfer (aLDT), or reverse shoulder arthroplasty (RSA)...

Distal biceps injuries, which usually occur in active middle-aged men, can result in chronic pain and loss of supination and flexion strength3 ,4 . Surgical repair of a ruptured distal biceps tendon can reliably decrease pain and improve strength compared with nonoperative management3 ,4 . However, even following successful healing and rehabilitation of a surgically repaired biceps tendon, full supination strength is rarely restored5 -7 . The expected outcome following distal biceps repair using a traditional anterior approach is a measurable loss of rotational strength, especially from neutral to supinated positions5 ,7 ...

Lesions of the long head of the biceps brachii tendon (LHBT) are a common source of shoulder pain and dysfunction. Although the exact role of the LHBT in shoulder biomechanics is not clearly understood, pathological involvement of this tendon is a well-known pain generator and frequently the clinical presentation consists of both anterior pain and flexion loss. The initial treatment for lesions of the LHBT should be nonoperative, but if that fails or if the LHBT lesion is combined with rotator cuff lesions or other lesions that need to be repaired surgically, surgical intervention is indicated...

Proximal-distal differences in muscle activity are rarely considered when defining the activity level of hamstring muscles. The aim of this study was to determine the inter-muscular and proximal-distal electromyography (EMG) activity patterns of hamstring muscles during common hamstring exercises. Nineteen amateur athletes without a history of hamstring injury performed 9 exercises, while EMG activity was recorded along the biceps femoris long head (BFlh) and semitendinosus (ST) muscles using 15-channel high-density electromyography (HD-EMG) electrodes...

AIM: To determine whether magnetic resonance imaging (MRI) signs of subscapularis (SBT), supraspinatus (SST), or superior labral tearing predict long head of biceps (LHB) tendon tearing at arthroscopy. MATERIALS AND METHODS: Subjects with MRI studies followed by arthroscopy were collected. Radiologists graded rotator cuff (RC) tendons and the superior labrum using three grade classifications and blinded to arthroscopy. Correlation between imaging variables and surgical outcome was expressed in terms of odds ratios and determined using a stepwise logistic regression model...

RATIONALE: Venlafaxine is an antidepressant and anxiolytic agent that functions by inhibiting central serotonin and norepinephrine reuptake, and it is a relatively recently introduced drug. In particular, overdose of venlafaxine has been reported to cause severe cardiac toxicity including ventricular tachycardia, prolongation of QT interval, and seizure or severe muscular injury. However, reports describing venlafaxine-induced rhabdomyolysis with neuropathy remain scarce. Accordingly, we report such a case involving a 49-year-old woman with bilateral sciatic neuropathy combined with rhabdomyolysis following venlafaxine overdose...

Background: Poor results after repair of type 2 SLAP tears are relatively common and some have reported better results after biceps tenodesis or tenotomy than repair. In addition, some believe that the long head of the biceps is expendable. Therefore, many now favor biceps tenotomy or tenodesis over biceps anchor repair either in all patients or in older patients, reserving SLAP lesion repair only for young athletes. Hypothesis: We hypothesized that repair of the biceps anchor of the labrum would be effective in all patients regardless of age provided that care was taken not to overtighten the labrum and that rotator cuff pain as the primary pain generator had been ruled out...

Background: The surgical treatment of a Superior Labrum Anterior and Posterior (SLAP) lesion becomes more and more frequent as the surgical techniques, the implants and the postoperative rehabilitation of the patient are improved and provide in most cases an excellent outcome. Objective: However, a standard therapy of SLAP lesions in the shoulder surgery has not been established yet. An algorithm on how to treat SLAP lesions according to their type and data on the factors that influence the surgical outcome is essential for the everyday clinical practice...

Massive irreparable rotator cuff tears without glenohumeral degeneration in young and active patients remain a challenging clinical problem for shoulder surgeons. Superior capsular reconstruction with fascia lata autograft or dermal allograft has recently become a popular treatment option. The long head of the biceps tendon, which has otherwise widely fallen into disfavor with shoulder surgeons, has recently emerged as an interesting alternative graft choice for superior capsular reconstruction because of its local availability...

BACKGROUND: Hemiplegic shoulder pain (HSP) is one common complication after stroke. The interferes with the functionality of the affected shoulder in patients with stroke during rehabilitation. Hyaluronic acid (HA) could have positive effects on pain relief and shoulder motion in stroke patients with hemiplegic shoulders. We investigated long-term benefits of HA injection in stroke patients with HSP and rotator cuff injury. METHODS: A randomized, double-blinded controlled trial was conducted in one medical center...

Tenodesis of the long head of the biceps tendon is a frequently performed procedure during shoulder arthroscopy. Various open and arthroscopic techniques have been described with comparable outcomes and complication rates. We describe a simple, knotless, arthroscopic extra-articular biceps tenodesis technique using a 4.5-mm knotless anchor. This technique avoids the complications associated with open tenodesis surgery while still removing the diseased biceps tendon from the bicipital groove. The benefits from knotless suture anchor include no requirement of arthroscopic knot tying and no risk of the knot irritation under the coracoid and coracoacromial ligament...
