  • Objective : To analyze the relationship of concomitant foraminallumbar disc herniation (FLDH) with postoperative leg pain after microdecompression for extraforaminallumbar disc herniation (EFLDH) at the L5-S1 level. Methods : Sixty-five patients who underwent microdecompression for symptomatic EFLDH at the L5-S1 level were enrolled, According to the severity of accompanying FLDH, EFLDH was classified into four categories (Class I : no FLDH; Class II : mild to moderate FLDH confined within a lateral foraminal zone; Class III : severe FLDH extending to a medial foraminal zone; Class IV : Class III with intracanalicular disc herniation). The incidence of postoperative leg pain, dysesthesia, analgesic medication, epidural block, and requirement for revision surgery due to leg pain were evaluated and compared at three months after initial surgery. Results : The incidences of postoperative leg pain and dysesthesia were 36.9% and 26.1%, respectively. Pain medication and epidural block was performed on 40% and 41.5%, respectively, Revision surgery was recommended in six patients (9.2%) due to persistent leg pain, The incidences of leg pain, dysesthesia, and requirement for epidural block were higher in Class III/IV, compared with Class I/II. The incidence of requirement for analgesic medication was significantly higher in Class III/IV, compared with Class I/II (p=0,02, odds ratio=9,82). All patients who required revision surgery due to persistent leg pain were included in Class III/IV. Conclusion : Concomitant FLDH seems related to postoperative residual leg pain after microdecompression for EFLDH at the L5-S1 level.

  • Cauda equina syndrome (CES) associated with dural ectasia is a rare neurologic complication in patients with longstanding ankylosing spondylitis (AS). We report a 68-year-old male with a 30-year history of AS who presented a typical symptom and signs of progressive CES, urinary incontinence and neuropathic pain of the lumbosacral radiculopathy. Computed tomography (CT) and magnetic resonance imaging (MRI) findings showed the unique appearances of dural ectasia, multiple dural diverticula, erosion of posterior element of the lumbar spine, tethering of the conus medullaris and adhesion of the lumbosacral nerve roots to the posterior aspect of the dural ectasia. Considering the progressive worsening of the clinical signs, detethering of the conus medullaris through resection of the filum terminale was performed through a limited laminectomy. However, the urinary incontinence did not improve and there was a partial relief of the neuropathic leg pain only. The possible pathogenetic mechanism of CES-AS and the dural ectasia in this patient with longstanding AS are discussed with a literature review.

  • 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.

  • This study was to investigate the effectiveness of combined Korean medicine treatment on a patient who was diagnosed on lumbosacral transitional vertebra (LSTV) with localized bone marrow edema. The patient was treated with acupuncture, pharmacopucture, cupping and herbal medicine. We evaluated patient's progress using range of motion (ROM), EuroQol-5 dimensions (EQ-5D), Oswestry disability index (ODI), numerical rating scale (NRS), patient global impression of change, self-walkable distance. NRS of back pain decreased from 7 to 5, at the same time NRS of lower limb decreased from 4 to 3. EQ-5D score increased from 0.24 to 0.646. ODI score improved 80 to 62. Self-walkable distance and lumbar spine ROM also increased. As a result, clinical improvements were found in a patient. In conclusion, this study shows that Korean medicine treatment can be considered as effective conservative care for LSTV with localized bone marrow edema.

  • Objective: To compare two testing protocols for evaluating range of motion (ROM) changes in the preloaded cadaveric spines implanted with a mobile core type Charite$^{TM}$ lumbar artificial disc. Methods: Using five human cadaveric lumbosacral spines (L2-S2), baseline ROMs were measured with a bending moment of 8 Nm for all motion modes (flexion/extension, lateral bending, and axial rotation) in intact spine. The ROM was tracked using a video-based motion-capturing system. After the Charite$^{TM}$ disc was implanted at the L4-L5 level, the measurement was repeated using two different methods: 1) loading up to 8 Nm with the compressive follower preload as in testing the intact spine (Load control protocol), 2) loading in displacement control until the total ROM of L2-S2 matches that when the intact spine was loaded under load control (Hybrid protocol). The comparison between the data of each protocol was performed. Results: The ROMs of the L4-L5 arthroplasty level were increased in all test modalities (p < 0.05 in bending and rotation) under both load and hybrid protocols. At the adjacent segments, the ROMs were increased in all modes except flexion under load control protocol. Under hybrid protocol, the adjacent segments demonstrated decreased ROMs in all modalities except extension at the inferior segment. Statistical significance between load and hybrid protocols was observed during bending and rotation at the operative and adjacent levels (p< 0.05). Conclusion: In hybrid protocol, the Charite$^{TM}$ disc provided a relatively better restoration of ROM, than in the load control protocol, reproducing clinical observations in terms of motion following surgery.

  • Objectives : The lumbosacral joint is unstable area from an anatomical viewpoint, while it is also a very mobile area in ordinary life, so that clinically major causes of low back pain originate in this joint. The purpose of this study is to assess the difference of the Ferguson's angles, Lumbar gravity lines, Lumbar lordotic angles among Herniated of Intervertebral Disc(HIVD) patients. Methods : We analyzed the lateral view of lumbar spine checked at erect position on 88 patients who had been diagnosed as HIVD by Magnetic Resonance Imaging(MRI). We investigated the Ferguson's angle, Lumbar gravity line, Lumbar lordotic angle on X-ray film. Results and Conclusions : In the acute lumbago group the Ferguson's angle had a tendency to decrease, while in the chronic group it had a tendency to increase. In the acute lumbago group the Lumbar gravity line fell in front of the normal range(sacrum), while in the chronic group it fell behind the normal range(sacrum). In the acute lumbago group the Lumbar lordotic angle usually decreased, while in the chronic group it increased. The Ferguson's angle and the Lumbar gravity line, the Ferguson's angle and the Lumbar lordotic angle, the Lumbar gravity line and Lumbar lordotic angle each had a positive realtionship. The Ferguson's angle, the Lumbar gravity line and the Lumbar lordotic angle was less influenced by the level of HIVD and was more influenced by how long the patient had the pain. The correlationship between each factor was less in the chronic lumbago group than the acute group. In the chronic lumbago group the instability of the lumbosacral joint increased, while in the acute group the compression of the weight on the sacrum increased.

  • It is well known that the lifetime incidence of low back pain is extraordinarily high, but those who incur the majority of the cost, both personally and financially, are the chronic pain. Stabilization programmers attracted our interest, with their aims of using the muscle system to protect spinal joint structures from further repetitive microtrauma, recurrent pain and degerative change. In overviewing the stabilizing role of the trunk and back mucles our attention became focused on muscles which controlled the lumbar and lumbosacral joints rather than on muscles which span the spine from the thorax to pelvis. It was considered that muscles such as the lumbar multifidus, transversus abdominis, and possibly also parts of the obliquus internus abdominis, would most likely function to stabilize the segments of the lumbar spine. In order to check if these muscles were functioning in low back pain patients, it was necessary to devise specific muscle tests. The new concept involves exercises using only relatively low activity levels in the muscles. More emphasis is placed on a motor skill which has to be relearned, practised and then gradully incorporated back into functional movement.

  • Chloroma is a localized myeloblastic tumor which may develop during the course of myelogenous leukemia or as a presenting sign of the disease. A 47-year-old female diagnosed as chronic myelogenous leukemia in her hematologic remission period complained of left lower leg pain. The lumbar-spine series showed multiple osteolytic changes in the left lateral border of the lumbar spine. An inhomogenous soft tissue mass involving left lateral aspects of lumbar vertebrae was identified by CT-scanning. At the first pain attack, lumbar epidural steroid and local anesthetic injection could abolish her pain and the patient could go a few days without pain. The following radiation therapy could also improve the symptom and retain the pain free interval. One month later, a second pain attack occurred and lumbar and caudal epidural steroid and local anesthetic injections could result only in an incidental relief of pain. Radiation and chemotherapy were started but failed to relieve pain. A neurolytic block was considered but the patient's general condition was aggravated and even verbal communication with her became impossible.

  • Foraminal decompression using a minimally invasive technique to preserve facet joint stability and function without fusion reportedly improves the radicular symptoms in approximately 80% of patients and is considered one of the good surgical treatment choices for lumbar foraminal or extraforaminal stenosis. However, proper decompression was not possible because of the inability to access the foramen at the L5-S1 level due to prominence of the iliac crest. To overcome this challenge, endoscopy-based minimally invasive spine surgery has recently gained attention. Here, we report the technical skills required in unilateral extraforaminal biportal endoscopic spinal surgery using a $30^{\circ}$ arthroscope to enable foraminal decompression at the L5-S1 level. Two 0.8-cm portals were created 2 cm lateral from the lateral border of the pedicles at the L5-S1 level. After sufficient working space was made, half of the superior articular process (SAP) in the hypertrophied facet joint was removed using a high-speed burr and a 5-mm wide osteotome, whereas the remaining inside part of the SAP was removed using a Kerrison punch and pituitary punch. The foraminal ligamentum flavum should be removed to inspect the conditions of the L5 exiting root and disc. Removing of the extruded disc could decompress the L5 root. The extraforaminal approach using a $30^{\circ}$ arthroscope is considered a minimally invasive alternative technique for decompressing foraminal stenosis at the L5-S1 level that preserves facet stability and provides symptomatic relief.

  • Objective : The goal of this study was to evaluate the biomechanical features of human cadaveric spines implanted with the Activ L prosthesis. Methods : Five cadaveric human lumbosacral spines (L2-S2) were tested for different motion modes, i.e. extension and flexion, right and left lateral bending and rotation. Baseline measurements of the range of motion (ROM), disc pressure (DP), and facet strain (FS) were performed in six modes of motion by applying loads up to 8 Nm, with a loading rate of 0.3 Nm/second. A constant 400 N axial follower preload was applied throughout the loading. After the Activ L was implanted at the L4-L5 disc space, measurements were repeated in the same manner. Results : The Activ L arthroplasty showed statistically significant decrease of ROM during rotation, increase of ROM during flexion and lateral bending at the operative segment and increase of ROM at the inferior segment during flexion. The DP of the superior disc of the operative site was comparable to those of intact spine and the DP of the inferior disc decreased in all motion modes, but these were not statistically significant. For FS, statistically significant decrease was detected at the operative facet during flexion and at the inferior facet during rotation. Conclusion : In vitro physiologic preload setting, the Activ L arthroplasty showed less restoration of ROM at the operative and adjacent levels as compared with intact spine. However, results of this study revealed that there are several possible theoretical useful results to reduce the incidence of adjacent segment disease.
