Posterior cervical foraminotomy is an attractive therapeutic option in selected cases of cervical radiculopathy that maintains cervical range of motion and minimize adjacent-segment degeneration. The focus of this procedure is to preserve as much of the facet as possible with decompression. Posterior cervical inclinatory foraminotomy (PCIF) is a new technique developed to offer excellent results by inclinatory decompression with minimal facet resection. The highlight of our PCIF technique is the use of inclinatory drilling out for preserving more of facet joint. The operative indications are radiculopathy from cervical foraminal stenosis (single or multilevel) with persistent or recurrent root symptoms. The PCIFs were performed between April 2007 and December 2009 on 26 male and 8 female patients with a total of 55 spinal levels. Complete and partial improvement in radiculopathic pain were seen in 26 patients (76%), and 8 patients (24%), respectively, with preserving more of facet joint. We believe that PCIF allows for preserving more of the facet joint and capsule when decompressing cervical foraminal stenosis due to spondylosis. We suggest that our PCIF technique can be an effective alternative surgical approach in the management of cervical spondylotic radiculopathy.

Purpose: Traumatic cervical SCI is frequently accompanied by dural tear and the resulting cerebrospinal fluid (CSF) leak after surgery can be troublesome and delay rehabilitation with increasing morbidity. This study evaluated the incidence of intraoperative CSF leaks in patients with traumatic cervical spinal cord injury (SCI) who underwent anterior cervical surgery and described the reliable management of CSF leaks during the perioperative period. Methods: A retrospective study of medical records and radiological images was done on patients with CSF leaks after cervical spine trauma. Results: Seven patients(13.2%) were identified with CSF leaks during the intraoperative period. All patients were severely injured and showed structural abnormalities on the initial magnetic resonance image (MRI) of the cervical spine. Intraoperatively, no primary repair of dural tear was attempted because of a wide, rough defect size. Therefore, fibrin glue was applied to the operated site in all cases. Although a wound drainage was inserted, it was stopped within the first 24 hours after the operation. No lumbar drainage was performed. Postoperatively, the patients should kept their heads in an elevated position and early ambulation and rehabilitation were encouraged. None of the patients developed complications related to CSF leaks during admission. Conclusion: The incidence of CSF leaks after surgery for cervical spinal trauma is relatively higher than that of cervical spinal stenosis. Therefore, one should expect the possibility of a dural tear and have a simple and effective management protocol for CSF leaks in trauma cases established.

Cervical foraminal stenosis is a disease in which the nerves that pass from the spinal canal to the limbs are narrowed and the nerves are compressed or damaged. Due to the lack of an imaging method that provides quantitatively stenosis, this study attempted to evaluate the area of the cervical vertebrae by reconstructing a three-dimensional computed tomography image, and to determine the area of the neural foramen in normal adults to calculate the stenosis rate. Using a three-dimensional image processing program, the surrounding bones including the posterior spinous process, lateral process, and lamellar bones of the cervical vertebra were removed so that the neural foramen could be observed well. A region of interest including the neural foraminal area of the three-dimensional image was set using ImageJ, and the number of pixels in the neural foraminal area was measured. The neural foraminal area was calculated by multiplying the number of measured pixels by the pixel size. To measure the largest neural foraminal area, it was measured between 40~50 degrees in the opposite direction and 15~20 degrees toward the head. The average area of the right C2-3 foramen was 44.32 mm², C3-4 area was 34.69 mm², C4-5 area was 36.41 mm², C5-6 area was 35.22 mm², C6-7 area was 36.03 mm². The average area of the left C2-3 foramen was 42.71 mm², C3-4 area was 32.23 mm², C5-6 area was 34.56 mm², and C6-7 area was 31.89 mm². By creating a reference table based on the neural foramen area of normal adults, the stenosis rate of patients with neural foraminal stenosis could be quantitatively calculated. It is expected that this method can be used as basic data for the diagnosis of cervical vertebral foraminal stenosis.

경추 신경공 협착은 모든 연령대의 비교적 많은 수의 사람들에게 침범하는 매우 흔한 척추 질환이다. 그러나 신경공 협착을 정량적으로 제공하는 영상검사법이 부족하므로, 본 연구는 3차원 전산화단층촬영상을 재구성하여 정량적인 측정방법을 제시하고자 한다. 3차원 영상처리 프로그램을 이용하여 경추의 후극돌기와 측돌기, 층뼈를 포함하여 신경공이 잘 관찰되도록 주변 뼈를 제거하였다. Image J를 이용하여 3차원 영상의 신경공 면적을 포함하는 관심영역을 설정하고, 신경공 면적의 화소수를 측정하였다. 측정 화소수에 화소크기를 곱하여 신경공 면적을 산출하였다. 가장 넓은 신경공 면적을 측정하기 위하여 측정 반대쪽 방향으로 40~50도 사이와, 머리쪽으로 15~20도 사이에서 측정하였다. 측정한 경추 신경공의 면적은 일관된 측정값을 보였다. 가장 크게 측정한 우측 신경공 C5-6 면적은 12.21 ㎟에서, 2년 후에 9.95 ㎟으로 18% 협착이 진행된 것을 알 수 있었다. 기존에 CT 검사 영상을 이용하여 3차원 재구성하므로 추가적인 방사선 피폭을 받지 않으며 신경공 협착 면적을 객관적으로 제시할 수 있다. 또한 3차원 영상을 보면서 신경공 협착 환자에게 설명하기 좋으며, 협착의 진행정도와 수술 후 평가에서도 사용하기 좋은 방법이라 사료된다.

A 66 year-old woman was admitted to our hospital for progressive weakness of both lower extremities since a month ago. Imaging study, based on plain X-ray, computed tomography and magnetic resonance image revealed spinal stenosis owing to anterior slipping of T10/11 segment. Degenerative spondylolisthesis is common in the lumbar spine and rarely occurs in the cervical spine. But there was no report of degenerative spondylolisthesis in thoracic spine. The authors experienced a case of degenerative spondylolisthesis in the thoracic spine. And we achieved a satisfactory result with posterior decompressive laminectomy alone.

A 14-month-old Thoroughbred colt with hind limbs lameness was referred to Equine Hospital of Jeju National University. During physical examination, the patient could not walk in a straight line but wobbled especially with hind limbs. He hesitated when backing and crossed hind limbs while circling tightly by protracting the outer hind limb keeping the inner hind limb stationed. Stenosis was observed between the 2nd (C2) and 3rd (C3), and the C3 and 4th (C4) cervical vertebrae on radiographs. The colt diagnosed as cervical stenotic myelopathy (CSM) based on the clinical signs and radiological findings. To confirm the diagnosis, postmortem computed tomography (CT) and histopathologic examination were performed after the euthanasia. The CT images revealed severe compression of the spinal cavity and cord between C3 and C4 cervical vertebrae. Grossly, there was compression of the spinal cord between the C3 and C4 cervical vertebrae. Histopathologically, severe axonal swelling and demyelination characterized by vacuolation and cavity formation were observed in the white matter of the spinal cord, especially in C3 and C4. CSM is problematic in the horse racing industry because of abnormal walking. This case report of CSM may offer information for diagnosis of the disease in the equine veterinary fields in the Republic of Korea.

Tubular retractor system as a minimally invasive surgery (MIS) technique has many advantages over other conventional MIS techniques. It offers direct visualization of the operative field, anatomical familiarity to spine surgeons, and minimizing tissue trauma. With technical advancement, many spinal pathologies are being treated using this system. Namely, herniated discs, lumbar and cervical stenosis, synovial cysts, lumbar instability, trauma, and even some intraspinal tumors have all been treated through tubular retractor system. Flexible arm and easy change of the tube direction are particularly useful in contralateral spinal decompression from an ipsilateral approach. Careful attention to surgical technique through narrow space will ensure that complications are minimized and will provide improved outcomes. However, understanding detailed anatomies and keeping precise surgical orientation are essential for this technique. Authors present the technical feasibility and initial results of use a tubular retractor system as a minimally invasive technique for variaties of spinal disorders with a review of literature.

Traction has been used since ancient times in the treatment of painfull spinal conditions, but the literature on traction and its clinical effectiveness Is limited. Traction can be defined as a drawing or pulling tension applied to a body segment. Cervical traction is a technique that applies a longitudinal force of the cervical spine and associated structures. Goals of traction include reduction of radicular signs and symptoms associated with conditions such as disk protrusion, degenerative disk disease, lateral stenosis, muscle spasm, and subluxations. The various mechanical factors most relevant to cervical traction are organized and discussed. The factors presented are 1) angle of pull, 2) Traction force, 3) duration of traction, 4) neck position and clinical application, and 5) frequency of treatment. It should allow physical therapists to adjust traction protocol to match the patient's symptoms and diagnosis. The purpose of this study is to provide a comprehensive overview of the cervical traction and treatment guidelines.

Synovial cysts are recognized as an uncommon cause of radicular and myelopathic symptoms. They are most frequently found in the lumbar region. The cervical spine or cervicothoracic junction is a rare location for a degenerative intraspinal synovial cyst as compared with the lumbar spine. At given cervical spinal levels, synovial cysts probably share clinical features with disc herniation and stenosis. However, the pathogenesis of synovial cysts remains still controversial. Here, we report a rare case of a synovial cyst in the lower cervical spine presented as Brown-Sequard syndrome and include a brief review of the literature. To the best of our knowledge, no previous report has been issued in the English literature on a synovial cyst presenting with Brown-Sequard syndrome. Neurologic function recovered completely after complete removal of the cyst and expansive laminoplasty.
