We present an elderly patient with unilateral foraminal stenosis treated by isthmus resection. An 83-year-old female could not walk due to severe leg pain along right L5 sensory dermatome. Despite the laminotomy for spinal stenosis on the right side at the L4-5 level, her leg pain did not improve. Careful review of computed tomography scans and coronal source images of magnetic resonance myelography revealed foraminal stenosis on the right side at the L5 vertebra. Because of medical problem, she underwent isthmus resection on the right side at the L5 level instead of total facetectomy and fusion. After surgery, her leg pain was markedly improved. Isthmus resection showed successful result for this medically compromised elderly patient with unilateral foraminal stenosis.

Vertebroplasty has drawn much attention as a medical treatment for the compression fracture of spine, which strengthens the vertebral body and corrects deformity, and relieves pain in patients by injecting bone cement. However vertebroplasty can cause fracture on adjacent vertebra due to relative stiffness change. This study involves the biomechanical evaluation of the vertebroplasty especially on adjacent vertebral body. The finite element method has been employed to analyze the patient who was treated vertebroplasty under static and dynamic loading. For this study, a three-dimentioal model of the three-level ligamentous lumbar segment ($L1{\sim}L3$)is created from medical image data (CT)and compared with the experimental results in vitro.

The presence of distant metastases from differentiated thyroid carcinoma decreases the 10-year survival rates of patients by 50%. This is a report of a 61-year-old female with follicular thyroid carcinoma who presented initially with low back pain. 2-deoxy-2-[18F] fluoro-D-glucose whole-body positron emission tomography/computed tomography (PET/CT) demonstrated a hypointensity lesion in the left thyroid gland with malignant uptake in L1 vertebra and magnetic resonance images revealed paravertebral and epidural extension of mass in L1 vertebra. After thyroidectomy, histopathological study showed a follicular carcinoma. We performed L1 total en bloc spondylectomy with expandable cage for long-term local control. The technical details of total en bloc spondylectomy in follicular carcinoma are described herein.

We propose an automatic vessel segmentation method of vertebral arteries in CT angiography using combined circular and cylindrical model fitting. First, to generate multi-segmented volumes, whole volume is automatically divided into four segments by anatomical properties of bone structures along z-axis of head and neck. To define an optimal volume circumscribing vertebral arteries, anterior-posterior bounding and side boundaries are defined as initial extracted vessel region. Second, the initial vessel candidates are tracked using circular model fitting. Since boundaries of the vertebral arteries are ambiguous in case the arteries pass through the transverse foramen in the cervical vertebra, the circle model is extended along z-axis to cylinder model for considering additional vessel information of neighboring slices. Finally, the boundaries of the vertebral arteries are detected using graph-cut optimization. From the experiments, the proposed method provides accurate results without bone artifacts and eroded vessels in the cervical vertebra.

Spondylolysis and spondylolisthesis are two conditions that directly involve changes in the vertebra. Spondylolysis is defined as a defect in the pars interarticularis, the region of the lamina between the superior and inferior articular facets. Progression of the defect can result in spondylolisthesis, which is defined as a subluxation or 'slippage' of two adjacent vertebrae. In the low back it occurs most commonly at the lumbosacral level; next in frequency is spondylolisthesis of the fourth lumbar vertebra on the fifth. To provide the reader with information about the aetiology and anatomical consideration of spondylolysis and spondylolisthesis type. Spondylolisthesis has recently been classified by Wiltse and others into five types based on the suspected aetiology; dysplastic, isthmic, degenerative, posttraumatic, pathologic and postsurgical. Of these five types, isthmic spondylolisthesi and degenerative spondylolisthesis, both of which are frequently associated with low back and lower limb pain.

These days, spinal interbody arthrodesis using fusion cage is very popular. The cage used for the spinal interbody arthrodesis is mainly inserted from the posterior of the spine. Accordingly, there could possibly occur damages at posterior and results in instability of structure. Moreover, one or two cages are inserted depending on the patients. In this study, it is attempted to evaluate the stability quantitatively by comparing two cases where one and two cages are inserted. For this purpose, a very fine 3-dimensional finite element model of vertebra is generated from the MRI data. From this vertebra model, two models are made: one with one cage and the other with two cages. Finally, finite element analys is performed for these two models and both of the mechanical behaviors are examined In addition, the effect on the stability is evaluated and compared quantitatively.

Stellate Ganglion (SG) of l0 cadavers were removed during autopsy at Saga Medical College. Length, width, thickness, shape and location of SG were measured before formalin fixation. The results are as follows; 1) Length, width, thickness of SG were 22.33+5.23mm, 9.34+2.23mm and 5.03+1.19mm in right respectively, and 29.67+10.56 mm, 11.29+3.20mm and 5.51+1.09mm respectively in left. 2) Weight of right SG is 0.69+0.25 gm and weight of left SG is 1.04+0.63 gm. 3) Shape of SG is oval and snowman type. 4) Location of SG is variably located from the base of 7th cervical vertebra to first thoracic vertebra.

We experienced a case of osteoid osteoma in thoracic vertebra accompanied with herniated nucleus pulposus during the management of back pain. A 32 year old male patient with herniated nucleus pulposus complained of back pain and radiation to right leg. Lumbar epidural block with 1% mepivacaine 5 ml was performed for pain control and it relieved the radiating pain. However patient continued to experience severe exacerated back pain at night which responded to aspirin. Therefore we performed further examination for existence of disease of the spine and diagnosed osteoid osteoma in the right pedicle of T12 vertebra. In conclusion, we recommend physicians when evaluating patients with back pain to be congnizant of possible existence of neoplastic disease of the spine and incorporate it in differential diagnosis.

To observe the anatomical structures which cause a cervicogenic headache it reports, from viewpoint of physical therapist in treatment multiple to observe method which approaches, the reporter it does. With the manipulation the vertebral manipulation effected an affirmative effect to cervicogenic headache(Niels Nilsson et al,1997). The manipulation, soft the tissue massage, postural education/advice, muscular elongation, the traction, and postural exercises initially came to be used with that technique which the upper cervical vertebra(0-C3) passive accessory intervertebral movement comes to be used with a cervicogenic headache treatment technique(Grant T & Niere K., 2000). Also, it relates with the diagnosis standard about a cervicogenic headache when the body function over of the cervical vertebra is discovered, the Muscle energy technique was proposed in the treatment which is safety and effect(Bogduk N,2001). The TENS and the Mange gave a reduction effect of pain often.

Craniovertebral junction (CVJ) tuberculosis is a rare disease, and potentially fatal due to the risk of atlantoaxial dislocation. The disease usually accompanies a retropharyngeal cold abscess, which can cause subsequential otolaryngologic symptoms such asdysphagia, odynophagia, or airway obstruction. Such a patient must be handled with great care to avoid a disaster. The disease is diagnosed with microbiological or other laboratory tests on the pus collected through puncture and aspiration, which will need otolaryngologic skills. For treatment, otolaryngologists play an important role by doing incision and drainage of the retropharyngeal abscess, or by attending the transoral vertebra surgery as partners with spine surgeons who will manage the CVJ lesions and ensure the craniocervical stability.
