CASE: A 37-year-old man with scapular winging, caused by combined palsy of the spinal accessory nerve and the long thoracic nerve, was successfully treated with a pectoralis major transfer to substitute for the serratus anterior muscle, and with levator scapulae and rhomboid muscle transfers to substitute for the trapezius muscle. CONCLUSION: The serratus anterior paralysis was thought to have occurred secondary to traction of the long thoracic nerve by the unsupported scapula following the spinal accessory nerve palsy...

OBJECTIVE: Head and neck (H&N) reconstruction after cancer resection is challenging. Myocutaneous trapezius flaps provide an alternative reconstruction for patients not suitable for microvascular free tissue transfer. METHODS: A systematic review was performed on studies involving trapezius flaps for H&N reconstruction post oncological resection between the years 1985-2015. Data extracted included patient numbers and demographics, operative technique and complications...

BACKGROUND: Brachial plexus injury is a complex entity that often results in partial recovery. Most studies to date have focused on improving shoulder abduction. However, a recent technique has been outlined-one that transfers the lower trapezius to improve the external rotation of the shoulder. The primary objective of this study was to evaluate the gains in external rotation of the shoulder in patients who have undergone transfer of the lower trapezius; secondarily, we assessed the range of motion in the elbow and shoulder joints, as well as the muscle strength and quality of life...

Management of failed rotator cuff repair may be difficult, especially in young patients. Various nonmodifiable and modifiable patient factors, including age, tendon quality, rotator cuff tear characteristics, acute or chronic rotator cuff tear, bone quality, tobacco use, and medications, affect rotator cuff repair healing. Surgical variables, such as the technique, timing, tension on the repair, the biomechanical construct, and fixation, as well as the postoperative rehabilitation strategy also affect rotator cuff repair healing...

BACKGROUND: Injury to long thoracic and the spinal accessory nerves can cause winging scapula as a result of weakness and paralysis of the trapezius and serratus anterior muscles. Although these nerve and muscle operations have been reported to correct winging scapula due to various causes, there is no report on comparing the outcomes of these procedures in peer-reviewed Pubmed-indexed literature. In this article, we compared the improvements in the restoration of shoulder functions in winging scapula patients after long thoracic nerve decompression (LTND) in our present study with outcomes of muscle and tendon transfer operations published in the literature (Aetna cited articles)...

Strengthening muscles of the back may have various implications for improving functions of daily living, aiding in the transfer of power in throwing, and assist in injury prevention of the shoulder complex. While several versions of the pull-up exist, there is currently no literature comparing their differences. The purpose of this investigation was to compare the electromyographical activity of the latissimus dorsi, posterior deltoid, middle trapezius, and biceps brachii while performing three variations of the pull-up...

Amyoplasia congenita, or "classic distal arthrogryposis," is the most common disorder among the congenital, non-progressive, multiple joint contractural conditions named arthrogryposis. The cause remains unknown, and it occurs sporadically. Abnormal neurological examination indicates that movement in utero was diminished as a result of an abnormality of the central or peripheral nervous system, the motor end plate, or muscle. The absence of central neural pathology indicates the origin in akinetic fetal condition...

BACKGROUND: Throwing requires proper stability and orientation of the pelvis and scapula for efficient energy transfer during pitching. Fatigue of the pelvis and scapular musculature throughout the course of a game can impair pitching performance, and place excessive demands on the throwing arm leading to injury. The purpose of this study was to examine differences in pelvis, torso, and upper extremity pitching mechanics and muscle activations between the fastball, change-up, and curveball pitches in youth baseball pitchers following a simulated game...

Tendon transfer options to reconstruct a massive irreparable posterior-superior rotator cuff tear include latissimus dorsi, teres major, or lower trapezius transfer. We previously described the lower trapezius transfer using a 2-incision approach, which includes a medial incision to harvest the lower trapezius and lateral transacromial incision to expose the rotator cuff and then perform the transfer through a deep tunnel connecting these 2 sites. In this report, we describe an arthroscopic-assisted technique of lower trapezius transfer augmented with an Achilles tendon allograft to reconstruct an irreparable posterior-superior rotator cuff tear...

INTRODUCTION: Facial reanimation surgery is performed in severe cases of facial palsy to restore facial function. In a 1-stage procedure, the spinal accessory nerve can be used as a donor nerve to power a free gracilis muscle transplant for the reanimation of the mouth. The aim of this study was to describe the surgical anatomy of the spinal accessory nerve, provide a guide for reliable donor nerve dissection, and analyze the available donor axon counts. METHODS: Dissections were performed on 10 nonembalmed cadavers (measurements of 20 nerves)...

Spinal accessory nerve (SAN) injury results in loss of motor function of the trapezius muscle and leads to severe shoulder problems. Primary end-to-end or graft repair is usually the standard treatment. The authors present 2 patients who presented late (8 and 10 months) after their SAN injuries, in whom a lateral pectoral nerve transfer to the SAN was performed successfully using a supraclavicular approach.

RANDOMIZED CONTROLLED TRIAL
Yin-Liang Lin, Andrew Karduna
Rotator cuff and scapular muscle strengthening exercises are an essential part of shoulder rehabilitation and sports training. Although the effect of exercise training on pain and function have been widely investigated, few studies have focused on the changes in shoulder kinematics and muscle activity after exercise training. Therefore, the purpose of the present study was to investigate the effect of rotator cuff and scapular strengthening exercises on shoulder kinematics and the activation of rotator cuff and scapular muscles in healthy subjects...

In-gyu Yoo, Won-gyu Yoo
BACKGROUND: Previous research has suggested eliminating certain types of manual material handling (MMH) work by recommending specific arm angles and postures to avoid, such as arm flexion or abduction over 90°. MMH with arm flexion over 90° can require lifting objects as well as lowering objects. However, few studies have evaluated MMH work while lowering objects in detail. OBJECTIVE: This study investigated the effects of different lifting and lowering heights on upper arm, shoulder, and back muscle activity during a MMH task...
