  • The fused lumbar vertebrae (L) of the female Cheju native horse were observed macroscopically. The 5th L and 6th L were partially fused. They were composed of four parts between the spinous process of the 5th L and 6th L, left and right transverse process of the 5th L and 6th L, caudal articular process of the 5th L and cranial articular process of the 6th L, and fossa of vertebra of the 5th L and head of vertebra of the 6th L. The dorsal lumbar foramen and ventral lumbar foramen were formed each at left and right of medial parts in the fused transverse processes of the 5th and 6th lumbar vertebrae.

  • Two species of mantid shrimps were collected from southern part of Korea and identified as Kempella mikado and Squilloides leptosquilla of the Squillidae. The former species is characterized by having a dactylus of the raptorial claw with six teeth, only the fifth thoracic somite with a single spinous lateral process, and the fifth abdominal somite with a pair of black dorsal patches. However, the latter species is characterized by having a dactylus of the raptorial claw with four teeth, and the fifth to seventh thoracic somites each with a single lateral process. Both species are described with figures and photographs. The present records are extensions of their geographical distributions and new records in Korea. Hence, a total of six species of the stomatopods have been recorded in Korea up to date: Oratosquilla oratoria, Faughnia formosae, Taku spinosocarinatus, Chorisquilla spinosissima, Kempella mikado, and Squilloides leptosquilla.

  • A three specimen of Icelus toyamensis, belonging to Cottidae, Scorpaeniformes, was firstly collected from the East Sea, Korea during 2007-2009. We herein described the species as the first record from Korea on the basis of these specimens. Icelus toyamensis is characterized by the following morphological combinations: spinous scales absent on the base of dorsal fin; small ctenoid scales scattered on body sides; gill rakers are short, tubular, and relatively broad; the uppermost preopercular spine is sharp and simple; dorsal fin rays VIII-IX, 20-21; anal fin soft rays 18-19; pectoral fin rays 18, and vertebrae 40-41. New Korean name of I. toyamensis is proposed as "Min-jul-ga-si-hoet-dae."

  • Existing orthopedic implants such as pedicle screw and spinal cage were designed to fix the spinal structure. But, nowadays, physicians want to rehabilitate there original functions. To achieve this request, we studied micro-movable structure for interspinous. As a first step, we designed interspinous structure by 3D CAD to join each spinous processes. Next, we simulate it with various factors such as the thickness of micro-movement structure and the design of clip. At last, we performed static compressive test to satisfy the failure load of 339N and dynamic endurance test of 1.2M cycle. As a result, we developed interspinous implant and did several surgery to evaluated its satisfaction.

  • We report the first occurrence of a tailless Girella leonina, collected from Jeju Island, Korea, in July 2016. This specimen has 10 scales below the median spinous portion of the dorsal fin, a black posterior margin of the operculum, and no pale vertical band on the body, and is therefore similar to the normal species, except that it has no caudal peduncle or caudal fin. The posterior parts of the dorsal and anal fins are gathered vertically at the posterior end of the body. A radiograph indicates that this abnormal specimen is lacking the vertebrae after vertebra 20.

  • A 55-year-old woman was seen in the emergency department with posterior neck pain and a headache after a traffic accident. Physical examination revealed tenderness on palpation over the posterior skull and a midline spinous process of the cervical spine without neurologic deficit. A plain radiograph of the cervical spine demonstrated the absence of the lateral portion of the posterior arch of the atlas and very lucent shadowing of the anterior midline of the atlas, suggesting a fracture of the anterior arch. On three-dimensional computed tomography (CT) of the cervical spine, anterior and posterior bony defects of the atlas were noted. Well-corticated defects were noted with sclerotic change and with no evidence of soft tissue swelling adjacent to the bony discontinuities, consistent with a congenital abnormality. With conservative therapy, the patient gradually showed a lessening of the midline tenderness. Careful investigation with radiography or CT is needed for these patients to avoid confusion with a fracture, because these patients seldom need surgical treatment.

  • Eight specimens (330.2~431.3 mm TL) of the family Zoarcidae were collected from the costal waters of the Byeonsanbando, Yellow Sea, Korea. They were identified as a Zoarces elongatus Kner based on the following characters: a dorsal fin with 14~16 notch-shaped spinous rays, irregular 13~16 dark spots in a row along the median body and 126~132 vertebrae. We proposed a new Korean name, 'Mu-jeom-deung-ga-si-chi', for the species.

  • Paravertebral anesthesia for operation of abdominal wall in Korean cattle were effectively accomplished with the following technique. Any problems in surgical procedure were not observed under the block of ventral branches of the last thoracic nerve and the first and second lumbar nerves with the administration of preanesthetic. The site of injection for blocking of ventral branches of the thirteenth thoracic nerve were approximately 5cm lateral to the midline from the posterior edge of spinous process of the 13th thoracic vertebra and about 10ml of local anesthetic was injected immediately anterior to the transverse process of the first lumbar vertebra through thin site. The block of ventral branches of the first and second lumbar nerves were obtained by injecting 10ml of local anesthetic immediately below the posterior edge of transverse process of the 2nd and 4th lumbar vertebra, respectively.

  • The crossing laminar screw fixation might be the most recently developed approach among various fixation techniques for C2. The new construct has stability comparable to transarticular or transpedicular screw fixation without risk of vertebral artery injury. Quantitative anatomical studies about C2 vertebra suggest significant variation in the thickness of C2 lamina as well as cross sectional area of junction of lamina and spinous process. We present an elderly patient who underwent an occipito-cervical stabilization incorporating crossed C2 laminar screw fixation. We preoperatively recognized that she had low profiles of C2 lamina, and thus made a modification of trajectory for the inferiorly crossing screw. We introduce a simple modification of crossing C2 laminar screw technique to improve stability in patients with low laminar profiles.

  • The current case report describes an uncommon insertion of the levator scapulae (LS), which broadly attaches to multiple structures, including the serratus posterior superior, ligamentum nuchae, and the 6th and 7th spinous processes of the cervical vertebrae. The most superior portion of this aponeurosis merged with the ligamentum nuchae at the C7 level. The middle and inferior portions of the head were inserted (or fused) into the tendon of the rhomboid minor as well as the fibers of the serratus posterior superior muscle. Consequently, recognizing this anatomical variation, characterized by an additional slip of the LS attaching to the 7th vertebra and other muscular structures, is crucial not only for anatomists but also for surgeons performing procedures on the posterior neck related to cervical or shoulder pain and cervical dystonia.
