Background: Excessive pronation of the feet can cause excessive inner rotation of the femur, followed by increased stress in the gluteus maximum, increased front slope of the pelvis, and lumbar lordosis, which leads to lumbar pain. The aim of the present study was to use the navicular drop test to examine foot pronation that can cause lumbar lordosis and to determine whether the navicular drop is lower in patients diagnosed with lumbar disc than in patients without this diagnosis. Methods: The Navicular Drop score was set by subtracting the navicular height at a standing position from the navicular height in a sitting position. The Navicular Drop measurements for college student with and without Lumbar Herniated Intervertebral Disc were compared using an independent t-test. Results: The control group were measured right $7.44{\pm}2.96$ and left $8.04{\pm}3.23$. The experimental group were measured right $2.12{\pm}1.33$ and left $2.80{\pm}1.29$. Therefore significant difference was found between the two groups (p<0.05). Conclusions: The navicular drop affected lumbar herniated intervertebral disc.

A four-year-old female Pekingese dog was presented with intermittent ambulatory hindlimb lameness and severe back pain. The course of the disease was acute and static and 5 days passed by until presentation. In neurological examination, severe back pain and slightly decreased proprioception in right hindlimb were shown. In radiographic examination, radiopacity was increased at T10-11 intervertebral disc space. According to the history taking, neurological examination and radiographic examination, it was tentatively diagnosed as intervertebral disc disease (IVDD). Conservative treatment was performed including cage rest, medication with prednisolone and traditional acupuncture. Acupoints were GV-6, GV-7, BL-18, BL-19. BL-40 and GB-34. Dry needlings rested for 20 minutes. Just after the first acupuncture treatment back pain was significantly decreased. With additional acupuncture treatment, all the clinical signs were not observed. It is considered that conservative therapy including traditional acupuncture, medication and cage rest might be the first choice of therapeutic method for Grade I or II IVDD in dogs.

Purpose: The pelvic tilting exercise is a well recognized rehabilitation maneuver. However, little information is available on the changes of lumbar segmental motion during pelvic tilting. This study was conducted to measure the kinematics of the pelvic tilting exercise on the supine and prone positions via fluoroscopy. Methods: A total of 10 female subjects were enrolled. During anterior, neutral, and posterior pelvic tilting, radiographs were taken in each exercise via fluoroscopy (ARCADIS Orbic, Siemens, USA). Images were sent to the picture archiving communication system (PACS), and the digitized images were analyzed using LabVIEW software (National Instruments, USA). Lumbosacral lordosis and the intervertebral body angle, intervertebral disc angle, and intervertebral displacement were analyzed. Results: The results of lumbar kinematic analysis during three tilting postures in the supine and prone positions demonstrated that lumbosacral lordosis and the intervertebral body angle and intervertebral disc angle were significantly higher when the pelvis was tilted anteriorly (p>0.05). However, there was no significant difference between anterior and neutral tilting in the intervertebral disc angle at the L3/4 level in the prone position (p>0.05), and there was no significant difference among tilting positions in intervertebral body displacement in the prone position (p>0.05). Conclusion: This study provides scientific evidence about the pelvic tilting exercise in lumbosacral segmental motion. Depending on the pelvic tilting exercise, kinematic changes were demonstrated in both positions, especially in the supine position. It is suggested that the supine position is effective for mobility, but it should be used carefully for the LBP (Low back pain) patient with hypermobility.

Objective : Morphometric data for the lumbar posterior longitudinal ligament (PLL) was investigated to identify whether there is a difference in the morphometry of the PLL of the lumbar spine at each level with respect to the pattern of intervertebral disc displacement. Methods : In 14 formalin-fixed adult cadavers (12 males and 2 females), from L1 to L5, the authors measured the width and height of the PLL and compared them with other landmarks such as the disc and the pedicle. Results : Horizontally, at the upper margin of the disc, the central portion of the superficial PLL covered 17.8-36.9% of the disc width and the fan-like portion of the PLL covered 63.9-76.7% of the disc width. At the level of the median portion of the disc, the PLL covered 69.1-74.5% of the disc width. Vertically, at the level of the medial margin of the pedicle, the fan-like portion of the PLL covered 23.5-29.9% of the disc height. In general, a significant difference in length was not found in the right-left and male-female comparisons. Conclusion : This study presents the morphometric data on the pattern of intervertebral disc displacement and helps to improve the knowledge of the surgical anatomy of the lumbar PLL.

척추사이구멍은 인접한 두 척추뼈와 그 사이의 척추사이원반으로 구성된다. 이전의 척추사이구멍에 대한 연구들은 다양한 방법으로 수행이 되었다. 이번 연구에서는 실리콘 주형을 이용해서 척추사이구멍의 특징을 알아보았다. 시신18구를 해부하여 허리의 척추사이구멍을 해부하였다. 첫째로는 척수신경의 위치를 측정하였다. 둘째로는 척추사이구멍을 덮고있는 모든 조직을 제거하여 척추사이구멍 단면의 가장 좁은 부위를 측정하였다. 조직이 제거된 척추사이구멍은 실리콘주형으로 채워졌다. 실리콘주형이 굳어진 다음에는 구멍에서 분리되었다. 단면으로 잘린 실리콘주형을 종이 위에 도장처럼 찍고, 그것을 컴퓨터에 저장하였다. 척추사이구멍의 주형의 면적, 둘레, 높이, 폭이 컴퓨터에서 분석되었다. 허리의 다섯 개 척추사이구멍에서 면적과 둘레는 통계학적인 차이를 보이지 않았다. 하지만 둘째에서 다섯째 허리뼈에 걸쳐서 높이는 낮아지는 경향, 폭은 넓어지는 경향을 보였다. 또한 높이와 폭은 다섯째 구멍에서 유의미한 차이가 있었다. 높이는 다른 구멍들 중에서 가장 낮았고, 폭은 가장 넓었다. 척수신경은 첫째에서 넷째허리뼈에서는 척추사이원반 근처를 지나갔고, 다섯째허리뼈에서는 척추사이원반 아래쪽으로 지나갔다. 이번 연구는 척추사이구멍의 3차원적 입체 구조를 실리콘주형으로 확인하였다. 기존의 평면적 연구에서 관찰되지 않았던 다른 성질들을 확인할 수 있었다. 즉, 허리척추뼈에서 척추사이구멍의 면적과 둘레는 일정하였으나 높이와 폭은 전체적으로 변화하는 양상을 보였다.

The purpose of this study is to investigate the potential of a novel tissue engineering approach to regenerate intervertebral disc. In this study, thermosensitive scaffold (chitosan-Pluronic hydrogel) and nanofiber were used to replace the nucleus pulposus (NP) and annulus fibrosus of a degenerated intervertebral disc, leading to an eventual regeneration of the disc using the minimally invasive surgical procedure and organ culture. In preliminary study, disc cells were seeded into the scaffolds and cellular responses were assessed by MTT assay and scanning electron microscopy (SEM). Based on these results, we could know that tissue engineered scaffolds might provide favorable environments for the regeneration of tissues. Organ culture was performed in fresh porcine spinal motion segments with endplates on both sides. These spinal motion segments were classified into three groups: control (Intact), injured NP (Defect), and inserting tissue engineered scaffolds (Insert). The specimens were cultivated for 7 days, subsequently structural stability, cell proliferation and morphological changes were evaluated by the relaxation time, quantity of DNA, GAG and histological examination. In these results, inserting group showed higher relaxation time, reduced decrement of DNA contents, and accumulated GAG amount. Consequently, the tissue engineered scaffolds used in this study seen to be a promising base scaffolds for regenerative intervertebral disc due to its capacity to absorb external dynamic loading and the possible ideal environment provided for disc cell growing.

Purpose: The majority of patients with radiculopathy caused by a herniated nucleus pulposus (HNP) heal spontaneously without surgery. The aim of this report is to describe the spontaneous regression of lumbar disc herniation and the results of clinical follow-up. Methods: Three patients with radiating low back pain presented with an extruded intervertebral disc on magnetic resonance imaging (MRI). We performed follow-up with conservative treatment (epidural injection, medication, physical therapy, exercise) and clinical assessments on the 6th, 10th and 22nd months. Results: The extruded intervertebral disc almost complete regressed, and correlated with clinical improvement and follow-up MRI. Conclusion: Conservative treatment can be an effective approach for a herniated lumbar discs if no neurological deficits are present.

Objectives : The purpose of this study is to find out the relationship between hip internal rotation angle and the level of herniation of lumbar intervertebral disc(HIVD) in single-segment. Methods : We investigated 314 patients (158 male, 156 female) who were diagnosed as herniation of lumbar intervertebral disc(HIVD) in single-segment. We measured 314 patients' hip internal rotation angle and analysed the relationship between the hip internal rotation angle and the level of herniation of lumbar intervertebral disc(HIVD). Results : 1. Among 314 cases, the hip internal rotation angle was different between male and female. Hip internal rotation angle of male was mainly limited and that of female was mainly excessive. 2. Among 314 cases, the normal group, defined as patients who have specific range of hip internal rotation angle(male : $35^{\circ}{\pm}10^{\circ}$, female : $45^{\circ}{\pm}10^{\circ}$), tends to be occurred HIVD at L4/5 level. The limited group, defined as patients who have less angle than normal group, the excessive group, defined as patients who have more angle than normal group, and the complex group, defined as patients who have more angle of one leg and less angle of the other leg than normal group, tend to be occurred HIVD at L5/S1 level(p<0.05). Conclusions : In single-segment lumbar HIVD patients, The normal hip internal rotation angle mainly leads to L4/5 HIVD, while the limited and excessive hip internal rotation angle mainly lead to L5/S1 HIVD.
