    Changsu Kim , Young-Ho Kwon , So Hak Chung and 1 other persons | 2016, 23(4) | pp.207~215 | number of Cited : 0
    Study Design: Retrospective study. Objectives: To evaluate the clinical efficacy and safety of radiofrequency (RF) ablation therapy followed by a bone cement augmentation procedure in treating and managing pain among metastatic spine tumor patients. Summary of Literature Review: As a metastatic spine tumor is unresectable, this procedure was performed. Results showed an increase in the necrosis rate, and a decrease in local recurrence and secondary vertebral stability. Materials and Methods: From March 2007 to April 2016, 26 patients who were treated with RF ablation with a bone cement augmentation procedure and the same number of patients treated with radiotherapy for metastatic spine lesions were included in this study. Pain relief and functional quality of life were evaluated using a visual analogue scale (VAS) and Roland Morris Questionnaire (RMQ). Results: VAS scores preoperatively and at 1, 4, and 12 weeks follow-up were 7.45, 3.01, 3.78, and 2.97 in the procedure group, and 7.04, 6.65, 5.87, and 3.03 in the radiotherapy group. The procedure group had significantly better average outcomes than the radiotherapy group for pain relief at 4 weeks but showed no difference at 12 weeks. The RMQ score improved from 13.92 to 7.21 in the procedure group, and from 15.33 to 9.75 in the radiotherapy group. Two patients who had a metastatic tumor near the vertebral body posterior cortex showed cement leakage into the disc space, that is, intraforaminal and intracanal space; therefore, operations were performed (7.69% nerve injury). Conclusions: RF ablation therapy with cement augmentation in treatment of metastatic spine tumor shows effectiveness in early pain relief and brings immediate vertebral stability, helping patients return to normal life. However, it carries a risk of nerve injury due to cement leakage.

    Kim Young Yul , 박찬주 , Kee-Won Rhyu | 2016, 23(4) | pp.216~222 | number of Cited : 0
    Study Design: Retrospective clinical study. Objectives: To assess the efficacy of a cortical bone trajectory pedicle screw (CBT-PS) for the treatment of lumbar pyogenic spondylodiscitis. Summary of Literature Review: Pedicle screws were used for surgical treatment of pyogenic spondylodiscitis to prevent instability and deformity. CTB-PS are typically inserted from the inferomedial to superolateral direction of the pedicle and have yielded satisfactory results in degenerative or osteoporotic spinal disorders. Materials and Methods: Eight patients with single segment lumbar pyogenic spondylodiscitis were analyzed. At first, anterior debridements and interbody fusions were perfomed with autogenous strut bone grafts, followed by posterior fixations and fusions with CBT-PS. The lordotic angles of operated levels were checked at the preoperative, postoperative, and final follow-ups. Visual analogue scales (VAS) were checked at the preoperative and final follow-ups. Results: Lesion sites were found at four L3-4, three L4-5, and one L2-3. Follow-ups were held at 26.13±8.23 months. The lordotic angles at preoperative, postoperative, and final follow-ups were 12.13±3.09°, 14.63±3.16°, and 12.75±3.99°, retrospectively. There were significant differences between results from the preoperative-postoperative and postoperative-final follow ups. There was no difference in the preoperative-final follow up. There was a significant difference between the VAS at the preoperative and final follow-ups (8.13±0.83 and 2.38±0.92, retrospectively). Complete bony unions of were observed at the final follow-up in all cases. Conclusions: The advantages of using a CBT-PS for lumbar pyogenic spondylodiscitis included the ability to minimize damage from the screw for both the posterior structure damage and the operated anterior area to prevent instability and deformity, and to achieve rigid bone union. CBT-PS is a potential surgical option for pyogenic spondylodiscitis.

    Jaeyoung Lee , 정승재 , 김윤수 | 2016, 23(4) | pp.223~226 | number of Cited : 0
    Study Design: A case report. Objectives: To report a rare case of intractable psoas abscess due to delayed diagnosis of colon tuberculosis. Summary of Literature Review: Most psoas abscesses occur primarily or secondarily due to infection of the vertebral body or discs; however, in rare cases, the etiology is not musculoskeletal in nature. In such cases, since diagnosis and treatment of the causal factor can be delayed, the psoas abscess may recur multiple times and eventually become difficult to treat. Materials and Methods: An 18-year-old female patient visited our institution complaining of right lower quadrant abdominal pain and right hip pain. On abdominal computed tomography (CT), a psoas abscess was observed and colon tuberculosis was suspected. She was treated with a ultrasonographically guided percutaneous drainage procedure. Considering the possibility of colon tuberculosis and related fistulae, a barium enema was performed; nonetheless, no fistula was found. After 2 months, the psoas abscess recurred, and thus incision and drainage were performed. Symptoms redeveloped 4 months after the incision and drainage; the patient was further evaluated with magnetic resonance imaging and recurrence of psoas abscess was again observed; incision and drainage were performed once again. A gross draining sinus developed on the right lower abdomen 11 months after the last procedure. On barium enema and abdominal CT scan, an enterocutaneous draining sinus was spotted at the right ascending colon, and right hemicolectomy was thus performed. Results: The psoas abscess did not recur during an 8-year follow-up period after right hemicolectomy. Conclusions: In treatment of secondary psoas abscess, diagnosis and treatment of the etiology is crucial.

    KIM JUN YOUNG , Woo-Kie Min , 김주은 and 2 other persons | 2016, 23(4) | pp.227~233 | number of Cited : 0
    Study design: Case Report. Objectives: The aim of this study was to report 2 cases of calcified spinal meningioma that displayed differences in appearance during resection, and to review the current literature on calcified and ossified spinal meningiomas. Summary of Literature Review: Calcified and ossified spinal meningiomas are rare, and tumor calcification is a risk factor for poor neurological outcomes resulting from the additional manipulations required to dissect the tumor. Materials and Methods: We describe the clinical course and intraoperative findings of 2 female patients who presented with symptoms of myelopathy. Magnetic resonance imaging showed calcified spinal meningiomas of the thoracic spine. The type of tumor resection performed was dependent on the solidity and texture of the individual tumors. Results: Pathologic evaluation revealed psammoma bodies, which suggested calcified meningioma. The patients’ neurologic symptoms resolved with no neurologic sequelae. Conclusions: Although there are a few pathologic differences regarding the main type and pathogenesis of ossified and calcified meningioma, both are thought to have a poor prognosis. For these tumors, adequately accounting for the expected poor prognosis and performing a wide laminectomy in order to ensure an adequate surgical margin are important factors for achieving a favorable outcome.

    The Co - occurance of Meningitis and Para - spinal Infection after Repetitive Procedural Treatment of the Spine - A Case Report -

    문종욱 , Suk-Joong Lee | 2016, 23(4) | pp.234~238 | number of Cited : 0
    Study Design: Case report. Objectives: We report a case of meningitis combined with paraspinal infection in a patients who underwent numerous surgeries for and repetitive procedural treatment of the spine. Summary of Literature Review: In patients with a history surgical and repetitive procedural treatment of the spine, one symptom of infection may be a fever with localized pain or tenderness along the spine. Materials and Methods: A 69-year-old man was hospitalized due to pyrexia and myalgia. Eight years ago, he underwented spine surgery. After that, the patient underwent spinal intervention more than once per week in another hospital due to remaining pain. One week before his visit to the emergency room, myalgia and aggravation in the lower back arose. However, a paraspinal infection was not detected in a non-enhanced MRI. One day after admission, the patient showed signs of meningeal irritation signs and the the patient’s mental state suddenly deteriorated. An emergency cerebrospinal fluid analysis showed typical findings of bacterial meningitis. An enhanced MRI of the brain showed pachymeningeal enhancement. An enhanced MRI of the spine showed a small abscess formation on the left paravertebral back muscle, and bilateral psoas muscle. Results: Serrtia marcescens was identified on blood cultures obtained upon admission. Since antibiotics were used to treat Serratia marcescens, the fever subsided, and the patient’s mental status returned to normal. Conclusions: For patients with a history of repetitive procedural treatments of the spine, a fever should be acknowledged as a symptom in meningitis or other infectious conditions.

    Basic Pelvic Parameters Associated with Lumbar Degenerative Disease - Review Article -

    주윤석 , 조재환 | 2016, 23(4) | pp.239~245 | number of Cited : 1
    Study Design: Literature review. Objectives: The aim of this study was to present updated information on the basic pelvic parameters associated with lumbar degenerative disease. Summary of Literature Review: Sagittal imbalance has been known to be related to a poor prognosis in almost all adult spine problems, including lumbar degenerative disease. Materials and Methods: Review of the relevant literature. Results: Pelvic incidence is a morphologic parameter of the pelvis. It influences lumbar lordosis and thoracic kyphosis, and determines the limitations of pelvic retroversion in sagittal imbalance. Pelvic tilt is a positional parameter of the pelvis, indicating the degree of compensation for sagittal imbalance. A C7-sagittal vertical axis >5 cm, pelvic tilt >20°, and pelvic incidence-lumbar lordosis mismatch are known to be independent factors predictive of poor outcomes. Conclusions: The C7-sagittal vertical axis, pelvic tilt, and pelvic incidence-lumbar lordosis mismatch should be considered when surgery is planned for a patient with degenerative lumbar disease.

    Yung Park , PARK, SE JUN , Jae-Young Hong and 1 other persons | 2016, 23(4) | pp.251~261 | number of Cited : 0
    Study Design: Literature review. Objectives: The aim of this study was to demonstrate surgical strategies for successful minimally invasive transforaminal lumbar interbody fusion (TLIF). Summary of Literature Review: Although many studies have reported the benefits and disadvantages of minimally invasive TLIF, few have described surgical strategies to improve the success rate or to reduce complications. Materials and Methods: We searched for studies reporting the clinical and radiological outcomes of minimally invasive TLIF, and analyzed the optimal indications, technical pitfalls, and tips for successful surgical outcomes. Results: The ideal candidate for minimally invasive TLIF is a patient with single or 2-level low-grade adult degenerative or isthmic spondylolisthesis. Incomplete decompression, dura tearing, nerve root injury, and implant-related complications were found to be the most commonly reported adverse events, especially in the early periods of a surgeon’s experience. Precise positioning for skin incision and tube insertion, complete neural decompression, proper interbody preparation for bone graft and cage insertion, and the correct placement of percutaneous pedicle screws are critical strategies for successful surgical outcomes. Fully understanding the surgical pitfalls and tips described in this review is also important to avoid potential complications. Conclusions: It is imperative not only to carry out a comprehensive preoperative evaluation and proper patient selection, but also to perform meticulous surgical procedures with thoughtful considerations of potential pitfalls, in order to improve the success rate and to reduce the complications of minimally invasive TLIF.

    Minimally Invasive Lateral Lumbar Interbody Fusion: Surgical Technique and Review

    Jaewan Soh , Jae Chul Lee | 2016, 23(4) | pp.262~269 | number of Cited : 0
    Study Design: Review of the current surgical technique and literature. Objectives: The aim of this study was to review the surgical technique and the current evidence on minimally invasive lateral lumbar interbody fusion (LLIF). Summary of Literature Review: Spinal fusion is a useful method in the treatment of various degenerative lumbar diseases. Recently, minimally invasive LLIF has been developed, enabling spine surgeons to perform anterior interbody fusion in a minimally invasive manner. Materials and Methods: Review of the surgical technique and the literature. Results: Minimally invasive LLIF may reduce the incidence of complications of anterior lumbar interbody fusion. LLIF may restore disc height more effectively than posterior lumbar interbody fusion and indirectly decompress the neural canal without nerve root or dural retraction or perineural scaring. The current indications for LLIF are almost equivalent to those of anterior and posterior lumbar interbody fusion. Recent studies have reported no differences in the fusion rate or clinical outcomes between LLIF and the conventional anterior or posterior interbody fusion techniques. However, LLIF has nonspecific complications, such as anterior thigh pain and hip flexor weakness. Conclusions: Minimally invasive LLIF is a promising surgical alternative to the conventional anterior or posterior fusion techniques. LLIF has the advantages of less intraoperative bleeding and soft tissue injury, and a faster return to work. However, postoperative nonspecific complications are problems that need to be addressed.
