Bilateral dislocation of the long head of biceps tendon with intact rotator cuff tendon: A case report.

Background: Dislocation of the long head of biceps tendon (LHBT) usually involves rotator cuff injury, and isolated dislocation with an intact rotator cuff is rare. Some cases of isolated dislocation have been reported. However, to the best of our knowledge, there has been no report of bilateral dislocation of the LHBT without rotator cuff pathology.

Arthroscopic suprapectoral biceps tenodesis provided earlier shoulder function restoration compared with open subpectoral biceps tenodesis during the recovery phase.

Background: This study compared the clinical outcomes of open subpectoral biceps tenodesis and arthroscopic suprapectoral biceps tenodesis for symptomatic biceps tenosynovitis. Although both techniques have pros and cons, no studies have compared clinical and functional outcomes during the recovery phase. Previous studies show that suprapectoral tenodesis has a higher probability of Popeye deformity and postoperative bicipital pain and stiffness, whereas subpectoral tenodesis has a higher risk of nerve complications and wound infections.

Partial infraspinatus tear with bursitis following an mRNA vaccination: a case report.

Unlabelled: We report a case of a shoulder injury related to vaccine administration (SIRVA) that developed symptoms 2 weeks following a coronavirus disease 2019 (COVID-19) vaccination and improved after receiving both intraarticular and subacromial corticosteroid injections.

Presentation Of Case: A 52-year-old Thai female without preexisting shoulder pathology and symptom had developed left shoulder pain for 3 days. Two weeks prior to shoulder pain, she received an mRNA COVID-19 vaccination.

The effectiveness of a Botulinum Toxin A infiltration in the management of bicipital cramps after arthroscopic biceps tenotomy.

A challenging complication of arthroscopic biceps surgery is the persistent painful cramping of the biceps. There is a paucity of data upon nonsurgical treatment of this debilitating complication. We pro- pose an intramuscular injection of botulinum toxin A (BTX-A) for painful bicipital cramping after tenotomy of the long head of the biceps brachii tendon (LHBT).

Long Head of the Biceps Tendon Ruptures: Biomechanics, Clinical Ramifications, and Management.

»: Pathology of the long head of the biceps tendon is a common source of shoulder pain and often occurs in combination with other shoulder disorders.

»: Nonsurgical management, including rest and activity modification, use of nonsteroidal anti-inflammatory drugs, physical therapy, and corticosteroid injections, is usually the first line of treatment.

»: Patients with symptoms that are refractory to nonsurgical management are indicated for biceps tenotomy or various tenodesis procedures.

Anatomical variations of the superficial ulnar artery: case series observed on historical specimens prepared by Ludwik Karol Teichmann.

Background: This report presents a series of cases representing variant origin and course of the ulnar artery, namely the superficial ulnar artery (SUA), observed during the review of collection of historical specimens prepared in the 19th century by the prominent Polish anatomist Ludwik Karol Teichmann and his collaborators, exhibited in the Anatomy Museum of Jagiellonian University Medical College.

Results: Three distinct variants of the SUA were found on anatomical specimens of the upper limb with arteries injected by using Teichmann's method. In case no.

Ultrasound-Guided Biceps Tendon Sheath Injections Frequently Extravasate Into the Glenohumeral Joint.

Purpose: To evaluate the frequency of glenohumeral joint extravasation of ultrasound (US)-guided biceps tendon sheath injections.

Methods: Fifty shoulders with a clinical diagnosis of bicipital tenosynovitis pain received a US-guided biceps sheath injection with anesthetic, steroid, and contrast (5.0 mL mixture) followed immediately by orthogonal radiographs to localize the anatomic distribution of the injection.

Characterization of Differences in the Time Course of Reflex and Voluntary Responses Following Botulinum Toxin Injections in Chronic Stroke Survivors.

Spasticity is a major impairment that can occur following a hemispheric stroke and is often treated with injections of botulinum toxin, a neurotoxin that impairs transmission at the neuromuscular junction. Hyperreflexia is a defining feature of spasticity. Our main objective here was to quantify the time course of changes in the deep tendon reflex (DTR) responses and voluntary activation capacity following BT injection as well as to track changes in a clinical assessment of spasticity.

An anatomical investigation into the blood supply of the proximal humerus: surgical considerations for rotator cuff repair.

Background: The purpose of this study was to investigate the blood supply of the humeral head (HH) originating from the anterior (ACHA) and posterior circumflex humeral arteries (PCHA).

Methods: Formalin preserved specimens were used to measure ACHA length, ACHA length in the bicipital groove (BG), the length of the ascending branch of the ACHA, the penetration point of the ascending branch of the ACHA at the greater tuberosity (GT), and the penetration point of the ascending branch PCHA at the GT. Fresh specimens were used to identify the intraosseous vascular network by both the ACHA and PCHA by injecting a contrast medium using a high-resolution microfocus computed tomography.

Ultrasound-guided versus palpation-guided corticosteroid injections for tendinosis of the long head of the biceps: A randomized comparative study.

Purpose: To compare accuracy, patient discomfort, and clinical outcome of ultrasound-guided versus palpation-guided corticosteroid injections to the bicipital groove in patients with long head of biceps (LHB) tendinosis.

Materials And Methods: Forty-four patients with primary LHB tendinosis were randomized into two groups (group A, n = 22; group B, n = 22). All patients underwent treatment with a single corticosteroid injection to the bicipital groove.

Ultrasound Visualization of Torsional Anatomic Changes From External Rotation of the Anterior Shoulder.

Unlabelled: The sonographic appearance of soft tissue can be altered with movement. This can be related to both position change as well as torsional stress. The objective of this article is to demonstrate sonographic anatomy of the anterior shoulder as it moves into full external rotation.

Atypical calcific tendinitis involving the long biceps tendon: A rare cause of hemiplegic shoulder pain.

Background And Objective: Calcific tendinitis is commonly found in the rotator cuff; however, it is very rare in the long biceps tendon (LBT). Furthermore, calcific tendinitis involving the LBT in the hemiplegic shoulder after a stroke has not been previously reported.

Materials And Method: We present a case of a 63-year-old man who suffers from a stroke and atypical calcific tendinitis involving the LBT as a rare cause of hemiplegic shoulder pain.

Biceps Tendon Sheath Injection: An Anatomical Conundrum.

Objective: Long head biceps tendon peritendinous or sheath injections are routinely administered at or immediately distally to the bicipital groove. The main indication for injection remains the clinical diagnosis or treatment of biceps tendinopathy, although true inflammation of the tendon within the bicipital groove is rare. Because the tendon sheath is merely an extension of the joint cavity, it is plausible to assume that an injection into the sheath would result in intraarticular spread.

Anatomic landmarks for arthroscopic suprapectoral biceps tenodesis: a cadaveric study.

Background: Biceps tenodesis reduces the incidence of Popeye deformity occurring with tenotomy, but pain may occur with tenodesis superior to or within the bicipital groove. Arthroscopic suprapectoral tenodesis is an attractive alternative. The purpose of this study was to establish landmarks for arthroscopic suprapectoral tenodesis and determine the appropriate fixation point to optimize muscle tension.

Point-of-Care Ultrasonography Findings and Care Use Among Patients Undergoing Ultrasound-Guided Shoulder Injections.

Objective: The aims of the study were to assess the overall reduction of pain in patients undergoing ultrasound-guided shoulder injections and to characterize the preinjection point-of-care ultrasound findings and use of clinical services postinjection including the use of magnetic resonance imaging and surgeries.

Design: Data of 172 patients who underwent ultrasound-guided subacromial subdeltoid injection or glenohumeral joint injection were reviewed for preinjection point-of-care ultrasound findings, change in pain intensity at 2 mos from baseline, and use of care at 6 mos' postinjection. Pain intensity was measured by the numeric rating scale and a dichotomous report of global impression of significant improvement in pain.

Arthrographic Anatomy of the Biceps Tendon Sheath: Potential Implications for Selective Injection.

The purpose of this investigation was to better define the anatomical features of the biceps tendon sheath, including the distance the sheath extends below the inferior margin of the subscapularis tendon and below the termination of the bony bicipital groove. A total of 110 magnetic resonance and computed tomography arthrograms performed during 1-year period at our institution were retrospectively reviewed, and the length of the biceps tendon sheath and distances from the inferior margin of the subscapularis tendon and from the termination of the bicipital groove to the inferior margin of the biceps tendon sheath were measured by 3 radiologists. The mean length of the biceps tendon sheath was 47.

Refuting the lipstick sign.

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.

Objective: To describe the volume and dimensions of the bicipital bursa and its position in relation to bony and soft tissue structures, in order to develop a novel medial synoviocentesis approach to the bicipital bursa.

Study Design: Cadaveric study.

Animals: Adult equine cadaver limbs (n=19).

Anatomical study of fibrous structures of the medial aspect of the canine elbow joint.

Forces exerted by fibrous structures on the medial aspect of the canine elbow joint have been reported to be involved in elbow pathology. The purpose of this paper is to assess the relationships of the ligamentous and muscular structures of this region of the canine elbow joint, and how they relate to the medial coronoid process. Six cadavers of adult German shepherd cross-breed dogs were used in this study to make intra-articular and vascular injections of this region.

Use of platelet rich plasma for the treatment of bicipital tendinopathy in spinal cord injury:: a pilot study.

The purpose of study is to explore the efficacy and safety of platelet rich plasma (PRP) in the nonoperative management of shoulder tendinopathy amongst individuals with spinal cord injury. This objective was met by completing a pilot study on the effectiveness and safety of a PRP injection into the biceps tendon demonstrating clinical and ultrasonagraphic pathology. Recent analysis of the preliminary pilot data has demonstrated remarkably convincing results demonstrating both the safety and efficacy of this novel intervention.

Accuracy of palpating the long head of the biceps tendon: an ultrasonographic study.

Objective: To determine the accuracy of palpating the long head of the biceps tendon (LHBT) within the intertubercular groove with the use of ultrasonographic localization as a gold standard.

Design: Prospective, single-blinded pilot study.

Setting: Sports medicine clinic at a tertiary care academic institution.

Fluoroscopically guided supraglenoid tubercle steroid injections for the management of biceps tendonitis.

Background: The management of bicipital tendonitis can be challenging to the clinician. Traditionally, blind injections near the bicipital groove have been performed by clinicians with risk of bicipital tendon rupture or atrophy. Because of the inaccuracy and risk associated with blind bicipital tendon steroid injections, we sought to ascertain whether a fluoroscopically guided steroid injection into the region of the origin of the long head of the bicipital tendon (supraglenoid tubercle) was efficacious.
