Between 1992 and 1996, 5 patients with the giant-cell tumor of the spine were treated. Four were female and one was male. The mean age was 34 years old, and the mean follow-up time was 36 months. The locations of the lesions were the cervical spine in 1, the thoracic spine in 3, and the lumbar spine in 1. Pain was the predominant presenting symptom in all cases and four had a neurological deficit. A combined anterior and posterior surgical approach wds as performed in all cases, which were also treated with AIF(anterior interbody fusion) and anterior and/or posterior instrumentation. Adjuvant radiation therapy was performed in 1 case of cervical spine. At the final follow-up, the pain and neurologic symptoms were improved. Radiologic examination showed no evidence of local recurrence and no failure of instrumentation of the spine.

Purpose: Pedicle screw fixation provides 3-column stabilization, multidimensional control, and a higher rate of interbody fusion. Although computed tomography (CT) is recommended for the postoperative assessment of pedicle screw fixation, its use is limited due to the radiation exposure dose. The purpose of this preliminary retrospective study was to assess the clinical usefulness of low-dose mobile cone-beam CT (CBCT) for the postoperative evaluation of pedicle screw fixation. Methods: The author retrospectively reviewed postoperative mobile CBCT images of 15 patients who underwent posterior pedicle screw fixation for spinal disease from November 2019 to April 2020. Pedicle screw placement was assessed for breaches of the bony structures. The breaches were graded based on the Heary classification. Results: The patients included 11 men and four women, and their mean age was 66±12 years. Of the 122 pedicle screws, 34 (27.9%) were inserted in the thoracic segment (from T7 to T12), 82 (67.2%) in the lumbar segment (from L1 to L5), and six (4.9%) in the first sacral segment. Although there were metal-related artifacts, the image of the screw position (according to Heary classification) after surgery could be assessed using mobile CBCT at all levels (T7-S1). Conclusions: Mobile CBCT was accurate in determining the location and integrity of the pedicle screw and identifying the surrounding bony structures. In the postoperative setting, mobile CBCT can be used as a primary modality for assessing the accuracy of pedicle screw fixation and detecting postoperative complications.

This study was conducted to identify the effect of meridian acupressure on defecation of patients with post spinal operation. The nonequivalent control group posttest only design was used. The data were obtained from 77 post spinal operative patients, 34 in the experimental 43 in control group in Y Hospital, Seoul, Korea. The neurosurgical unit A and B ward, assigned by matched sample by the name of operation such as laminectomy and posterior lumbar interbody fusion are performed. Meridian acupressure meant the method that an examiner presses response points distributed in the pass of energy vessel. In this study, meridian acupressure program was performed on as points in order of Hegue (LI-4), Zhigou (TE-6), Zusanli (S-36), Shangjuxu (S-37), Xiajuxu (S-39), Tianshu (S-25), Taichong (L-3) which was known to be related to large intestine. Data were collected from 1, July 2003 to 1, September 2003. Meridian acupressure program was carried out for 20 minutes 4 hours after operation twice daily. In order to evaluate the effect of meridian acupressure intervention, they were asked time of bowel recovery, gas passing, and defecation though questionnaire method. Data were analyzed by the SPSS/ WIN 11.0 program. The results of this study were summarized as follows; 1. Homogeneity tests of general characteristics and operation related characteristics of the experimental group and the control group were performed. General characteristics included age, sex, defecation habit, eating pattern, fluid intake, life style, activity, usage of laxative and etc. 2. Hypotheses were verification as follows; 1) Recovery of bowel sound of the experimental group who received meridian acupressure intervention was faster than that of the control group after spinal operation (t=-6.770,P=.000). 2) Time of gas passing of the experimental group who received meridian acupressure program was faster than that of the control group after spinal operation (t=-8.003, P=.000). 3) Time to defecation of the experimental group who received meridian acupressure program was faster than that of the control group after spinal operation (t=-9.026, P=.000). 4) Abdominal discomfort due to defecation of the experimental group who received meridian acupressure program was lesser than that of the control group after spinal operation (t=-3.431, P=.001). From these results, meridian acupressure intervention was effective for recovery of bowel sound, reduce time to gas passing, time to defecation and lessen abdominal discomfort due to defecation on post spinal operative patients. And therefore this intervention can probably considered on clinical practice.

Objective : Both the paraspinal muscle sparing approach and percutaneous screw fixation are less traumatic procedures in comparison with the conventional midline approach. These techniques have been used with the goal of reducing muscle injury. The purpose of this study was to evaluate and to compare the safety and efficacy of the paraspinal muscle sparing technique and percutaneous screw fixation for the treatment of L5-S1 spondylolisthesis. Methods : Twenty patients who had undergone posterior lumbar interbody fusion (PLIF) at the L5-S1 segment for spondylolisthesis were prospectively studied. They were divided into two groups by screw fixation technique (Group I : paraspinal muscle sparing approach and Group II: percutaneous screw fixation). Clinical outcomes were assessed by Low Back Outcome Score (LBOS) and Visual Analogue Scale (VAS) for back and leg pain at different times after surgery. In addition, modified MacNab's grading criteria were used to assess subjective patients' outcomes 6 months after surgery. Postoperative midline surgical scarring, intraoperative blood loss, mean operation time, and procedure-related complications were analyzed. Results : Excellent or good results were observed in all patients in both groups 6 months after surgery. Patients in both groups showed marked improvement in terms of LBOSs all over time intervals. Postoperative midline surgical scarring and intraoperative blood loss were lower in Group II compared to Group I although these differences were not statistically significant. Low back pain (LBP) and leg pain in both groups also showed significant improvement when compared to preoperative scores. However, at 7 days and 1 month after surgery, patients in Group II had significantly better LBP scores compared to Group I. Conclusion : In terms of LBP during the early postoperative period, patients who underwent percutaneous screw fixation showed better results compared to ones who underwent screw fixation via the paraspinal muscle sparing approach. Our results indicate that the percutaneous screw fixation procedure is the preferable minimally invasive technique for reducing LBP associated with L5-S1 spondylolisthesis.

Objective : C-reactive protein (CRP) level, erythrocyte sedimentation rate (ESR), and white blood cell (WBC) count are inflammatory markers used to evaluate postoperative infections. Although these markers are non-specific, understanding their normal kinetics after surgery may be helpful in the early detection of postoperative infections. To compliment the recent trend of reducing the duration of antibiotic use, this retrospective study investigated the inflammatory markers of patients who had received antibiotics within 24 hours after surgery according to the Health Insurance Review & Assessment Service guidelines and compared them with those of patients who had received antibiotics for 5 days, which was proven to be non-infectious. Methods : We enrolled 74 patients, divided into two groups. Patients underwent posterior lumbar interbody fusion (PLIF) at a single institution between 2019 and 2020. Group A included 37 patients who received antibiotics within 24 hours after the PLIF procedure, and group B comprised 37 patients who had used antibiotics for 5 days. A 1 : 1 nearest-neighbor propensity-matched analysis was used. The clinical variables included age, sex, medical history, body mass index, estimated blood loss, and operation time. Laboratory data included CRP, ESR, and WBC, which were measured preoperatively and on postoperative days (POD) 1, 3, 5, and 7. Results : CRP dynamics tended to decrease after peaking on POD 3, with a similar trend in both groups. The average CRP level in group B was slightly higher than that in group A; however, the difference was not statistically significant. Multiple linear regression analysis revealed operation time, number of fused levels, and estimated blood loss as significant predictors of a greater CRP peak value (r²=0.473, p<0.001) in patients. No trend (a tendency to decrease from the peak value) could be determined for ESR and WBC count on POD 7. Conclusion : Although slight differences were observed in numerical values and kinetics, sequential changes in inflammatory markers according to the duration of antibiotic administration showed similar patterns. Knowledge of CRP kinetics allows the assessment of the degree of difference between the clinical and expected values.
