However, the efficacy of drains used for this purpose in adolescent idiopathic scoliosis is controversial. The purpose of this study is to evaluate outcomes of patients after posterior spinal fusion with instrumentation for adolescent idiopathic scoliosis without wound suction drainage. Methods: A total of 66 Patients who underwent posterior spinal fusion and instrumentation for the correction of Adolescent idiopathic scoliosis without the use of drain from January 2012 to January 2021 were included. Wound dehiscence, wound hematoma, infection, preoperative and postoperative hemoglobin levels and need for transfusion were described as frequency and mean values. Results: The average age was 15.06 years. Hospital stay was 2.2 days. Patients were followed-up over 50.21 months. There was no deep infection, wound hematoma. The difference between just postoperative and three days after operation hemoglobin levels was not significant and no need for transfusion. Only 3 (4.5%) cases with superficial skin infection and 4 (6%) cases with skin and Wound dehiscence were treated with dressing and antibiotics with full recovery. Conclusion: Without using drain for patients with idiopathic scoliosis who underwent posterior spinal fusion and instrumentation, no increase in blood loss, transfusion requirements, wound infection, skin dehiscence, and wound hematoma was observed.展开更多

It has been reported to be an effective treatment modality in well selected patients. This procedure is however not without possible complications which can adversely affect the outcome of treatment in the affected patients. This prospective study was therefore undertaken to evaluate the early functional outcome of posterior spinal decompression for lumbar spinal stenosis at our health institution. Method: All patients with symptomatic lumbar spinal stenosis admitted for posterior spinal decompression and who met the inclusion criteria were recruited with their written informed consent. The patients’ pain severity and functional disability were assessed preoperatively with visual analogue scale (VAS) and Oswestry Disability Index (ODI). The VAS and ODI were also used to reassess the patients postoperatively, at 2 weeks, 6 weeks and 12 weeks respectively. All intraoperative and/or postoperative complications were documented and the results were analyzed. Results: The patients’ mean preoperative lower back pain and leg pain VAS score was 8.26 ± 1.46 while the mean preoperative ODI was 62.4% ±13.56. The commonest combination of spinal decompressive procedure done in the patients was laminectomy + foraminotomy in 10 (25% patients). The most common decompressed spinal level was L4/L5 (89.7%);while almost equal number of patients had either one spinal level or two-spinal level decompression (43.6% and 46.1% respectively). Postoperative pain assessment showed a mean VAS of 3.79 ± 1.15, 2.55 ± 1.27 and 2.00 ± 1.41 at 2 weeks, 6 weeks and 12 weeks respectively (p = 0.000). Functional outcome assessment with ODI was 34% ± 11.79%, 24% ± 10.75% and 18.12% ± 10.61% at 2 weeks, 6 weeks and 12 weeks respectively (p = 0.000). The commonest surgical complication seen was dura tear which occurred in nine patients (23.1%). Conclusion: There was significant reduction in low back and radicular pains with consequent functional improvement in majority of the patients who had posterior spinal decompression for lumbar spinal stenosis at our health institution. There were few complications of which dura tear was the commonest.展开更多

But the anterior operations often induce severe complications. Some surgeons choose posterior-only surgery with halo-femoral traction, posterior wide release and correction. But to the best of our knowledge, there are only rare prospective studies on these posterior-only surgeries for AIS patients who have a rigid curve more than 80~ and flexibility less than 35%. Methods Sixty-four AIS patients were recruited from September 2006 to June 2009. All patients had rigid curves and underwent spinal correction. They were randomly divided into group A （combined anteroposterior surgery） and group B （posterior-only surgery）. Images and scoliosis research society-22 questionnaire （SRS-22） scores were performed pre- and post-operation and during follow-up visits. The operation time, blood loss, hospital days, and hospital charges were compared between the two groups. Results These patients were followed for an average of 37.5 months （range, 24-65 months）. No serious complications were observed. There were no significant differences between the two groups in gender, age, preoperative radiographic data, or preoperative SRS-22 score. The average operation time, blood loss, hospital days and hospital charges in group B were less than those in group A. The SRS-22 score in group B was better than in group A at post-operation and at final follow-up. Conclusions In AIS with a rigid curve more than 80~ and flexibility less than 35%, strong halo-femoral traction with wide posterior spinal release and three dimensional spinal correction can provide better SRS-22 scores, comparable curve correction, shorter operation time, less blood loss, shorter hospital stays and lower charges when compared to combined anterior and posterior surgery.展开更多

Twenty-four patients with thoracic or lumbar spinal tuberculosis whose lesions were confined to adjacent segments were admitted to our hospital and treated. The American Spinal Injury Association（ASIA） impairment scale was used to assess the neurological function. All patients were treated with one-stage surgical treatment via a posterior-only approach. The clinical efficacy was evaluated by the Japanese Orthopaedic Association（JOA） scores and oswestry disability index（ODI） of nerve function. Patients were evaluated preoperatively and postoperatively by measurement of spinal deformity using Cobb angle and radiological examination. All the patients were followed up for 13 to 27 months. They had significantly postoperative improvement in JOA score, ODI and ASIA classification scores. The kyphotic angles were significantly corrected and maintained at the final follow-up. Bone fusion was achieved within 4–12 months. It was concluded that one-stage surgical treatment via a posterior-only approach is effective and feasible for the treatment of spinal tuberculosis.展开更多

There are v...Congenital pure kyphosis due to failure of vertebral body segmentation is a relatively rare entity, and surgical intervention is infrequent compared to that for failure of vertebral body formation [1] [2]. There are very few reports of long-term follow-up of surgical treatment in patients with congenital pure kyphosis, and all the reported cases were diagnosed as failure of formation and had an age at the time of surgery of less than 18 years. It is important for orthopedic surgeons to follow the postoperative course of rare cases over 30 years. Here, we present a surgically treated case with ultra-long term follow-up of a 50-year-old patient with congenital pure kyphosis of the lumbar spine. Imaging of the lumbar spine showed six vertebrae and an unsegmented bar at L3-4 causing a pure kyphosis of 54°. The wedge-shaped block vertebra had 4 pedicles with the neural foramen between the pedicles without concomitant disc space, with compensatory thoracic hypokyphosis and lower lumbar hyperlordosis. One-stage correction and fusion surgery using anterior opening and posterior closing osteotomy was successfully performed. Both clinical and radiographic results were excellent and have been maintained for over 30 years postoperatively. The basic principle in the surgical treatment of adult spinal deformity is to achieve and maintain a good global sagittal balance over time. This case reaffirms the importance of spinopelvic harmony.展开更多

But the anterior operations often induce severe complications. Some surgeons choose posterior-only surgery with halo-femoral traction, posterior wide release and correction. But to the best of our knowledge, there are only rare prospective studies on these posterior-only surgeries for AIS patients who have a rigid curve more than 80~ and flexibility less than 35%.
