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. -
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. -

S. CAVDAR and U. SEHIRLI the Extensor Indicis (Proprius)
Okajimas Folia Anat. Jpn. , 73(2-3): 139-142, August, 1996 The Accessory Tendon of the Extensor Indicis Muscle By S. CAVDAR and U. SEHIRLI Marmara University, Faculty of Medicine, Department of Anatomy, Haydarpasa 81326, Istanbul-Turkiye -Received for Publication, August 9, 1995- Key Words: Accessory tendon, Extensor Indicis Muscle, Variation Summary: The extensor indicis and the extensor pollicis longus muscles differentiates from the extensor digitorum profundus muscle. The extensor indicis musde is an unstable muscle concerning its variations. Kosugi (1989) found the frequency of variations of this muscle to be 20% and described 18 different types of variations of this muscle. This study describes a rare case of the extensor indicis muscle. The extensor indicis muscle develops an accessory tendon in between the extensor indicis and extensor pollicis longus muscle. It passes under the extensor retinaculum. At the level of 2nd metacarpal bone, the accessory extensor indicis tendon is connected to the tendon of the extensor pollicis longus muscle by a intertendinous connection. The extensor indicis (proprius) is a narrow quadrupeds have been classified by Straus (1941) elongated muscle located in the deep extensor group into three groups. of the forearm. It arises from the posterior surface of 1. Brachio-antebrachial group the ulna distal to the extensor pollicis longus and 2. Antebrachio-manual group from the interosseus membrane. Its tendon passes 3. Manual group under the extensor retinaculum in company with the The brachio-antebrachial group basically takes its tendons of extensor digitorum communis. At the origin from the dorsal aspect of the brachial bone level of the second metacarpal bone it joins the ulnar and inserts onto the antebrachial bones. -
7 the Soft-Tissue Anatomy of the Highly Derived Hand of Perodicticus Relative to the More Generalised Nycticebus
7 The Soft-Tissue Anatomy of the Highly Derived Hand of Perodicticus Relative to the More Generalised Nycticebus Marissa Boettcher, Kaitlyn C. Leonard, Anthony Herrel and Adam Hartstone-Rose 7.1 Introduction 7.1.1 Characteristics of Perodicticus The African lorisid subfamily Perodicticinae includes the slow-moving angwantibos (Arctocebus) and the pottos (Perodicticus) (Lambert, 2014), the focal taxon of this chapter. The distinguishing physical features of this subfamily include their short tails and vestigial manual second digit (Charles-Dominique, 1977a). Perodicticus potto, first described by Bosman in 1704 and further characterised by Müller in 1776 (Bosman, 1705; Müller, 1773; Smeenk et al., 2006), was originally placed in the genus Nycticebus by Geoffroy, but the subsequent rediscovery of the animal in Sierra Leone by Bennett in the early nineteenth century became the basis for his naming the genus Perodicticus (Bennett, 1831; Hill, 1953a; Smeenk et al., 2006). Perodicticus is the largest of the African lorisids and has a geographical distribution that includes West and Central Africa, extending from Liberia to Kenya (Chiarelli, 1972; Fleagle, 1999; Nekaris and Bearder, 2007; Poindexter and Nekaris, 2017a). On average, across the three known species, the males have an average body length of 337–406 mm and tail length of 50–81 mm, while the females are slightly smaller, with an average body and tail length of 355–417 mm and 56–72 mm, respectively (Chiarelli, 1972). Like most primates, they are arboreal and often main- tain a height of 30 m above the ground in the canopy (Lambert, 2014). 7.1.2 Locomotion and Limb Anatomy The locomotion of Perodicticus is highly characteristic of the species. -

Methods A total 80 forearms of 40 healthy volunteers were recruited. We identified midpoint (MP) of EI using ultrasound and set MP as optimal needle insertion point. The location of MP was suggested using distances from landmarks. Distance from MP to medial border of ulna (MP-X) and to lower margin of ulnar head (MP-Y) were measured. Ratios of MP-X to Forearm circumference (X ratio) and MP-Y to forearm length (Y ratio) were calculated. In cross-sectional view, depth of MP (Dmp), defined as middle value of superficial depth (Ds) and deep depth (Dd) was measured and suggested as proper depth of needle insertion. Results Mean MP-X was 1.37±0.14 cm and mean MP-Y was 5.50±0.46 cm. Mean X ratio was 8.10±0.53 and mean Y ratio was 22.15±0.47. Mean Dmp was 7.63±0.96 mm. Conclusion We suggested that novel optimal needle insertion point of the EI. -

Ahmed Farid Al-Neklawy, M.D. Anatomy and Embryology Department, Faculty of Medicine, Ain Shams University, Cairo, Egypt E-mail: [email protected], Tel: 00201001850336 Running title: Two extra muscles for thumb and index fingers Abstract Background: Variations of anomalies of hand extensors have been described by many authors. These anomalies are often discovered during routine surgical procedures and cadaveric dissections. Being aware of such anomalies is important to the physician in order to avoid unintentional damage to healthy tendons during surgical procedures. In addition, accessory tendons have the potential to be used in the surgical repair or replacement of damaged tendons. We reported a cadaveric case with bilateral two additional superficial extensors to the thumb and index fingers with unique features. The names of extensor pollicis longus superficialis (EPL-S) and extensor indicis superficialis(EI-S) were proposed. Methods: A female cadaver was used in this study. Bilateral dissection of the forearm and wrist was done. Results: Two extra muscles were observed in the superficial group of the extensors of the forearm. They were situated between extensor carpi radialis brevis and extensor digitorum muscles. Both muscles originated from the common extensor origin. -
