Introduction: The ductal syndromes of the shoulder combine all the compressive processes of the suprascapular nerve at the level of its passage in the spinoglenoid notch and this for several causes. The most common is a lesion of the labrum resulting in the formation of a cyst. These cysts are rare and often underestimated. Provoking a compression of the suprascapular nerve, they are likely to cause an atrophy of the external rotator muscles of the cuff. Case Report: We present a rare case of a paraglenoid cyst resulting in a ductal syndrome by suprascapular nerve compression...

Introduction: Entrapment of the suprascapular nerve is an uncommon but important differential in patients who present with posterior shoulder pain. Frequently misdiagnosed as rotator cuff or cervical disc disease, this increasingly recognized entity can result from traction-related or compression-related etiology. Two sites of compression include the suprascapular and spinoglenoid notches with the latter less commonly encountered. Case Report: In our study, we describe a case of arthroscopic decompression of suprascapular nerve entrapment at the spinoglenoid notch due to hypertrophied spinoglenoid ligament using an improvised arthroscopic technique...

Push-ups are regularly adapted for specific muscular demands. The push-up plus (PUP) has been used to emphasize serratus anterior activation. Alterations in body posture have been suggested for targeted activation of muscles surrounding the shoulder and rotator cuff, but little data exists to inform these changes. The purpose of this research was to examine upper extremity muscle activity changes when varying aspects of the PUP. Healthy male participants (n = 20) performed PUP trials using combinations of hand contact area (knuckles/palms), humeral rotation (neutral/60° internal/60° external) and hand location (shoulder height/±30% arm length superior/inferior) at a fixed cadence...

CONTEXT: Whereas alterations in scapular kinematics, scapulothoracic muscle activity, and pain sensitivity have been described in adult swimmers, no researchers have examined these outcomes in young swimmers. OBJECTIVES: To compare scapular kinematics, scapulothoracic muscle activation, and the pressure-pain threshold (PPT) of the shoulder muscles among young nonpractitioners (those who were not involved in sports involving the upper limbs), amateur swimmers, and competitive swimmers...

Dry needling is a widely used alternative therapy for musculoskeletal disorders, such as myofascial pain. The procedure involves placing a solid monofilament needle into myofascial trigger points or connective tissue to relieve pain. Some of the complications secondary to this procedure include cardiac tamponade, hematoma, infection, nerve injury, and pneumothorax. Although the incidence is low, the complications can be potentially life threatening. We present the case of a 44-year-old man who had dry needling of the infraspinatus, supraspinatus, rhomboid, and paraspinal muscles with subsequent development of a left apical pneumothorax...

AIM: To examine humeral retroversion in infants who sustained brachial plexus birth palsy (BPBI) and suffered from an internal rotation contracture. Additionally, the role of the infraspinatus (IS) and subscapularis (SSc) muscles in the genesis of this bony deformation is explored. METHODS: Bilateral magnetic resonance imaging (MRI) scans of 35 infants (age range: 2-7 mo old) with BPBI were retrospectively analyzed. Retroversion was measured according to two proximal axes and one distal axis (transepicondylar axis)...

BACKGROUND: Retear of repaired rotator cuff tendons worsens patient outcome and decreases patient satisfaction. Superior capsule reconstruction (SCR) was developed to center the humeral head and thus restore the force couple for patients with rotator cuff tears. PURPOSE: To evaluate whether SCR for reinforcement before arthroscopic rotator cuff repair (ARCR) improves cuff integrity. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Thirty-four consecutive patients (mean age, 69...

Paralabral cysts are an increasingly recognized cause of suprascapular nerve (SSN) impingement, often causing insidious weakness in the rotator cuff. Compression at the suprascapular notch is often due to the presence of a SLAP tear and leads to pain, weakness, and atrophy of both the supraspinatus and infraspinatus muscles. Compression of the SSN at the spinoglenoid notch leads to weakness and atrophy of the infraspinatus only. Arthroscopic decompression of cysts with repair of labral pathology is typically performed in a sublabral fashion, which may make visualization of the extent of the cyst difficult and places the SSN at increased risk...

INTRODUCTION: The manner in which imaging patterns change over the disease course and with increasing disability in dysferlinopathy is not fully understood. METHODS: Fibroadipose infiltration of 61 muscles was scored based on whole-body MRI of 33 patients with dysferlinopathy and represented in a heatmap. We trained random forests to predict disease duration, motor function measure dimension 1 (MFM-D1) and modified Rankin scale (mRS) based on muscle scoring and selected the most important muscle for predictions...

BACKGROUND: Axillary nerve injuries are uncommon, although the incidence is higher in athletes, both related to direct contusion or quadrilateral space syndrome. While few studies have investigated conservative strategies that could be proposed to avoid surgery, no previous case report documented the possible role of rehabilitation in axillary nerve re- injuries. CASE REPORT: Our patient is a 27-year-old male professional rugby player who experienced a recurrent episode of deltoid strength loss, after a previous axillary nerve injury...
