  • Effect of Preservation of the C-6 Spinous Process and Its Paraspinal Muscular Attachment on the Prevention of Postoperative Axial Neck Pain in C3–6 Laminoplasty
    SPINE CLINICAL ARTICLE J Neurosurg Spine 22:221–229, 2015 Effect of preservation of the C-6 spinous process and its paraspinal muscular attachment on the prevention of postoperative axial neck pain in C3–6 laminoplasty Eiji Mori, MD, Takayoshi Ueta, MD, PhD, Takeshi Maeda, MD, PhD, Itaru Yugué, MD, PhD, Osamu Kawano, MD, PhD, and Keiichiro Shiba, MD, PhD Department of Orthopaedic Surgery, Spinal Injuries Center, Iizuka, Fukuoka, Japan OBJECT Axial neck pain after C3–6 laminoplasty has been reported to be significantly lesser than that after C3–7 laminoplasty because of the preservation of the C-7 spinous process and the attachment of nuchal muscles such as the trapezius and rhomboideus minor, which are connected to the scapula. The C-6 spinous process is the second longest spinous process after that of C-7, and it serves as an attachment point for these muscles. The effect of preserving the C-6 spinous process and its muscular attachment, in addition to preservation of the C-7 spinous process, on the preven- tion of axial neck pain is not well understood. The purpose of the current study was to clarify whether preservation of the paraspinal muscles of the C-6 spinous process reduces postoperative axial neck pain compared to that after using nonpreservation techniques. METHODs The authors studied 60 patients who underwent C3–6 double-door laminoplasty for the treatment of cervi- cal spondylotic myelopathy or cervical ossification of the posterior longitudinal ligament; the minimum follow-up period was 1 year. Twenty-five patients underwent a C-6 paraspinal muscle preservation technique, and 35 underwent a C-6 nonpreservation technique.

  • Analysis of Isometric Cervical Strength with a Nonlinear Musculoskeletal Model with 48 Degrees of Freedom
    Multibody Syst Dyn (2016) 36:339–362 DOI 10.1007/s11044-015-9461-z Analysis of isometric cervical strength with a nonlinear musculoskeletal model with 48 degrees of freedom E. de Bruijn1 · F.C.T. van der Helm 1 · R. Happee1 Received: 15 May 2014 / Accepted: 8 May 2015 / Published online: 2 June 2015 © The Author(s) 2015. This article is published with open access at Springerlink.com Abstract Background: Musculoskeletal models served to analyze head–neck motion and injury during automotive impact. Although muscle activation is known to affect the kine- matic response, a model with properly validated muscle contributions does not exist to date. The goal of this study was to enhance a musculoskeletal neck model and to validate passive properties, muscle moment arms, maximum isometric strength, and muscle activity. Methods: A dynamic nonlinear musculoskeletal model of the cervical spine with 48 de- grees of freedom was extended with 129 bilateral muscle segments. The stiffness of the passive ligamentous spine was validated in flexion/extension, lateral bending, and axial ro- tation. Instantaneous joint centers of rotation were validated in flexion/extension, and mus- cle moment arms were validated in flexion/extension and lateral bending. A linearized static model was derived to predict isometric strength and muscle activation in horizontal head force and axial rotation tasks. Results: The ligamentous spine stiffness, instantaneous joint centers of rotation, muscle moment arms, cervical isometric strength, and muscle activation patterns were in general agreement with biomechanical data. Taking into account equilibrium of all neck joints, iso- metric strength was strongly reduced in flexion (46 %) and axial rotation (81 %) compared to a simplified solution only considering equilibrium around T1–C7, while effects were marginal in extension (3 %).

  • Scapular Winging Is a Rare Disorder Often Caused by Neuromuscular Imbalance in the Scapulothoracic Stabilizer Muscles
    SCAPULAR WINGING Scapular winging is a rare disorder often caused by neuromuscular imbalance in the scapulothoracic stabilizer muscles. Lesions of the long thoracic nerve and spinal accessory nerves are the most common cause. Patients report diffuse neck, shoulder girdle, and upper back pain, which may be debilitating, associated with abduction and overhead activities. Accurate diagnosis and detection depend on appreciation on comprehensive physical examination. Although most cases resolve nonsurgically, surgical treatment of scapular winging has been met with success. True incidence is largely unknown because of under diagnosis. Most commonly it is categorized anatomically as medial or lateral shift of the inferior angle of the scapula. Primary winging occurs when muscular weakness disrupts the normal balance of the scapulothoracic complex. Secondary winging occurs when pathology of the shoulder joint pathology. Delay in diagnosis may lead to traction brachial plexopathy, periscapular muscle spasm, frozen shoulder, subacromial impingement, and thoracic outlet syndrome. Anatomy and Biomechanics Scapula is rotated 30° anterior on the chest wall; 20° forward in the sagittal plane; the inferior angle is tilted 3° upward. It serves as the attachment site for 17 muscles. The trapezius muscle accomplishes elevation of the scapula in the cranio-caudal axis and upward rotation. The serratus anterior and pectoralis major and minor muscles produce anterior and lateral motion, described as scapular protraction. Normal Scapulothoracic abduction: As the limb is elevated, the effect is an upward and lateral rotation of the inferior pole of scapula. Periscapular weakness resulting from overuse may manifest as scapular dysfunction (ie, winging). Serratus Anterior Muscle Origin From the first 9 ribs Insert The medial border of the scapula.

ISSN 2321-4287 Original Research Article DOI: https://dx.doi.org/10.16965/ijar.2019.335 THE LEVATOR SCAPULAE MUSCLE – MORPHOLOGICAL VARIATIONS K. Satheesh Naik 1, Sadhu Lokanadham 2. *1 Assistant Professor, Department of Anatomy, Viswabharathi Medical College & General Hospital, Penchikalapadu, Kurnool, Andhrapradesh, India. 2 Associate Professor, Department of Anatomy, Santhiram Medical College and General Hospital, Nandyal, Andhrapradesh, India. ABSTRACT Introduction: Anatomical variations of the levator scapulae are important and therefore clinically relevant. The levator scapulae are now believed to be the leading cause of discomfort in patients with chronic tension-type neck and shoulder pain and a link between anatomical variants of the muscle and increased risk of developing pain has been speculated. The results obtained were compared with previous studies. Materials and methods: The study was conducted on 32 levator scapulae muscle of 16 cadavers over a period of 3 years. The dissection of head and neck was done carefully to preserve all minute details, observing the morphological variations of the muscle in the department of Anatomy, Viswabharathi Medical College, Penchikalapadu, and Kurnool. Results: Total 32 levator scapulae muscles were used. All the sample values were measured to 2 decimal places. The average age of the cadavers in the sample was 82.87 years. The oldest cadaver in the sample was 100 years old and the youngest 61 years. Measurements of the proximal and distal attachments and the total length of the muscles were taken. Between 3 and 6 muscle slips were reported at the proximal attachment.

Herein, absence INTRODUCTION he levator scapulae muscle (LSM) is a bilaterally symmetric muscle that Toriginates from the transverse processes of the first through fourth cervical vertebrae and inserts onto the superior angle of medial border of the scapula [1]. The LSM is in contact anteriorly with the middle scalene muscle, laterally with the sternocleidomastoid and trapezius muscles, posteriorly with the splenius cervicis muscle and medially with the posterior scalene muscle [2]. The LSM is innervated by the dorsal scapular nerve, as well as the anterior rami of the C3 and C4 spinal nerves. The primary function of the levator scapulae is elevating the scapula [1], however it has been suggested that it also assists in downward rotation of the scapula [2].

  • Levator Scapulae Muscle Asymmetry Presenting As a Palpable Neck Mass: CT Evaluation
    Levator Scapulae Muscle Asymmetry Presenting as a Palpable Neck Mass: CT Evaluation Barry A. Shpizner1 and Roy A . Hollida/ PURPOSE: To define the normal CT anatomy of the levator scapulae muscle and to report on a series of five patients who presented with a palpable mass in the posterior triangle due to asymmetry of the levator scapulae muscles. PATIENTS AND METHODS: The contrast-enhanced CT examinations of the neck in 25 patients without palpable masses were reviewed to es tablish the normal CT appearance of the levator scapulae muscle. We retrospectively reviewed the contrast-enhanced CT examinations of the neck in five patients who presented with a palpable mass secondary to asymmetric levator scapulae muscles . RESULTS: In three patients who had undergone unilateral radical neck dissection, hypertrophy of the ipsi lateral levator scapulae muscle was found. In one patient, the normal levator scapulae muscle produced a fa ctitious "mass" due to atrophy of the contralateral levator scapulae muscle. One patient had an intramuscular neoplasm of the levator scapulae. CONCLUSION: Asymmetry of the levator scapulae muscles , an unusual cause of a posterior triangle mass, can be diagnosed using CT.
