Osteochondromas are common, benign tumors in the long bones, but osteochondromas are rare in the vertebrae. Most vertebral osteochondromas arise from the cervical or upper thoracic spine. However, lumbar osteochondromas have rarely been reported. In this report, a rare case of a lumbar osteochondroma arising from the spondylolytic L3 lamina in a 57-year-old woman is presented. She also had a ruptured disc and lumbar canal stenosis at L4-5-S1. The osteochondroma was completely removed and a posterior lumbar interbody fusion and instrumentation were performed. Considering the rarity of osteochondromas in the lumbar vertebrae, especially the L3 vertebra, it is possible that the pre-existing lumbar spondylolysis or spondylolisthesis was one of the factors affecting the occurrence or progression of the osteochondroma.

Eighteen specimens of juvenile Mugilidae were collected in October 2012 from the southern coastal waters of Jeju Island, and identified based on analysis of their mitochondrial DNA16S rRNA sequences. Seventeen specimens of Oedalechilus labiosus and a single specimen of Ellochelon vaigiensis were found, constituting a new record for these species among Korean ichthyofauna. O. labiosus is identified by the angle at the posterior end of its mouth, which contains a round notch, a darkish dorsal margin of the pectoral fin, the presence of 33-36 lateral line scales, and 23-24 vertebrae. E. vaigiensis is identified by dark dorsal and pectoral fins, the presence of 26 lateral line scales, and 25 vertebrae. The proposed Korean name for Oedalechilus is 'Sol-ip-sung-eo-sok' and that for Ellochelon is 'Nup-jeok-ggo-ri-sung-eo-sok'. The proposed Korean names for the species are 'Sol-ip-sung-eo' and 'Nup-jeok-ggo-ri-sung-eo' for O. labiosus and E. vaigiensis, respectively. We present a key for identification of the Mugilidae family of species from Korea, and include these two newly recorded species.

The purpose of this study was to determine the changes of skin temperature and subjective fatigue of the thoracic vertebrae by the chiropractic adjustments. Stimulation of the sympathetic nervous system will cause the changes in the skin blood flow which can be detected by measuring the skin surface temperature. This study was to see whether chiropractic adjustments could affect the activity of the sympathetic nervous system as reflected by changes in skin temperature of the thoracic. Skin temperature and subjective fatigue on 16 subjects was measured before, within 10 sec, 10min, 20min and 30 min after a thoracic adjustment with Digital Infrared Thermal Imaging(DITI) and Visual Analogue Scale(VAS). The adjustments consisted of a straight posterior-to-anterior high-speed, low-amplitude thrust to the transverse process of T3-T10 using a reinforced hypothenar contact. The average temperature and fatigue changed when the spine was considered as an entire unit. These results illustrate that the blood flow through the soft tissue can be affected by specific adjustments to the spine. This study might be served as an useful baseline data for the changes of the circulation and fatigue after the chiropractic adjustments.

The purpose of this study is to clarify the mechanical behavior of human lumbar vertebrae (L3/L4) with and without fusion bone under physiological axial compression. The author has developed the program code to build the patient specific three-dimensional geometric model from the computed tomography (CT) images. The developed three-dimensional model provides the necessary information to the physicians and surgeons to visually interact with the model and if needed, plan the way of surgery in advance. The processed data of the model is versatile and compatible with the commercial computer aided design (CAD), finite element analysis (FEA) software and rapid prototyping technology. The actual physical model is manufactured using rapid prototyping technique to confirm the executable competence of the processed data from the developed program code. The patient specific model of L3/L4 vertebrae is analyzed under compressive loading condition by the FEA approach. By varying the spacer position and fusion bone with and without pedicle instrumentation, simulations were carried out to find the increasing axial stiffness so as to ensure the success of fusion technique. The finding was helpful in positioning the fusion bone graft and to predict the mechanical stress and deformation of body organ indicating the critical section.

Vertebroplasty (VP) can effectively treat pain and immobility caused by vertebral compression fracture. Because of complications such as extravasation of bone cement (polymethylmethacrylate, PMMA) and adjacent vertebral fractures, some practitioners prefer to inject a small volume of PMMA. In that case, however, insufficient augmentation or a subsequent refracture of the treated vertebrae can occur. A 65-year-old woman visited our clinic complaining of unrelieved severe low back and bilateral flank pain even after she had undergone VP on the $1^{st}$ and $4^{th}$ (L1 and L4) lumbar vertebrae a month earlier. Radiologic findings showed the refracture of L1. We successfully performed the repeat VP by filling the vertebra with a sufficient volume of PMMA, and no complications occurred. The patient's pain and immobility resolved completely three days after the procedure and she remained symptom-free a month later. In conclusion, VP with small volume cement impaction may fail to relieve fracture-induced symptoms, and the refracture of an augmented vertebral body may occur. In this case, repeat VP can effectively resolve both the persistent symptoms and problems of new onset resulting from refracture of the augmented vertebral body due to insufficient volume of bone cement.

Objective : Percutaneous vertebroplasty (PV) is a minimally invasive procedure designed to treat various spinal pathologies. The maximum number of levels to be injected at one setting is still debatable. This study was done to evaluate the usefulness and safety of multilevel PV (more than three vertebrae) in management of osteoporotic fractures. Methods : This prospective study was carried out on consecutive 40 patients with osteoporotic fractures who had been operated for multilevel PV (more than three levels). There were 28 females and 12 males and their ages ranged from 60 to 85 years with mean age of 72.5 years. We had injected 194 vertebrae in those 40 patients (four levels in 16 patients, five levels in 14 patients, and six levels in 10 patients). Visual analogue scale (VAS) was used for pain intensity measurement and plain X-ray films and computed tomography scan were used for radiological assessment. The mean follow-up period was 21.7 months (range, 12-40). Results : Asymptomatic bone cement leakage has occurred in 12 patients (30%) in the present study. Symptomatic pulmonary embolism was observed in one patient. Significant improvement of pain was recorded immediate postoperative in 36 patients (90%). Conclusion : Multilevel PV for the treatment of osteoporotic fractures is a safe and successful procedure that can significantly reduce pain and improve patient's condition without a significant morbidity. It is considered a cost effective procedure allowing a rapid restoration of patient mobility.

The determination of Sr-90 in 93 Korean vertebrae was carried out using modified method of tri-n-butyl phosphate extraction. As a result, the average content of Sr-90 in Korean vertebrae was 2.29 pCi/g Ca in the female and 1.73 pCi/g Ca in the male and the average level of both sexes was 2.01 pCi/g Ca, which was slightly higher than those of other countries. On the other hand, the Sr-90 injected into intraperitonal cavity of rat was accumulated in bones mostly and distributed evenly to various types of hones. The rate of accumulation and removal was not dependent on the amount of Sr-90 injected and over one half Sr-90 injected was accumulated in bones within one day and then it was removed gradually after two days from the injection.

This case report relates to a 40-year old male patient diagnosed with ankylosing spondylitis who was treated with acupotomy and traditional Korean medicine. He showed a significant improvement in joint range of motion (ROM) in cervical and lumbar vertebrae, and in pain and functional disorder symptoms. The patient received acupotomy, acupuncture, pharmacopuncture, herbal medicine and physical therapy (November 26, 2018 to December 17, 2018). Joint ROM for cervical and lumbar vertebrae was measured, and the pain level was assessed using a numerical rating scale. The functional disorder and quality of life scales were also assessed using the Bath Ankylosing Spondylitis Functional Index, Bath Ankylosing Spondylitis Disease Activity Index, Korean Health Assessment Questionnaire, and Modified Health Assessment Questionnaire. After applying acupotomy and traditional Korean medicine, the patient exhibited increased joint ROM and reduced pain, also in conjunction with improved responses in functional disorder and quality of life.

This study was carried out to observe the development of the autonomous skeletal development of the Favonigobius gymnauchen. Total length (TL) of larvae 3 days after hatching (DAH) were mean TL of 3.34 mm, with a line-shaped parasphenoid ossification in the cranium and basioccipital ossification in the back. The 10 DAH larvae had a mean TL of 5.20 mm, with the number of caudal vertebrae increasing to 15. The urostyle and two hypural bones in the lower part also began to ossify. The 23 DAH juveniles had a mean TL of 8.47 mm. The pectoral girdle's skeleton was completed as the scapula and coracoid were ossified. The pelvic girdle also fully supported the ventral fin as its ossification was completed. Favonigobius gymnauchen and Tridentiger obscurus showed similar characteristics in terms of the anus location of hatched larvae, number of myotomes, and melanophore distribution during the morphological development of the larvae and juveniles. However, this study confirmed differences in the development of the vertebrae and urostyle bone.

The butterfly vertebra is a rare congenital anomaly of the spine, which arises from an asymmetric fusion defect in the embryonic vertebral column. This report delineates an integrative Korean medicine treatment administered to two patients who presented with low back pain associated with asymptomatic butterfly vertebrae. The patients received comprehensive treatment comprising acupuncture, Chuna therapy, pharmacopuncture, herbal medicine, and cupping therapy. The efficacy of the treatments was assessed utilizing diverse parameters, including a numerical rating scale, range of motion of the lumbar spine, Oswestry Disability Index, EuroQoL 5-Dimension 5-Level, and patient global impression of change. After the treatment, a notable improvement was noted in the evaluated indicators. These positive outcomes suggest that integrative Korean medicine treatment is suitable for patients experiencing low back pain associated with asymptomatic butterfly vertebrae.
