Balloon kyphoplasty: an experience of 38 patients with painful osteoporotic vertebral compressive fractures / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of percutaneous balloon kyphoplasty as a new therapy for patients with painful osteoporotic vertebral compressive fractures of the lumbar and thoracic spine.</p><p><b>METHODS</b>A retrospective analysis was conducted in 38 consecutive patients (28 females, 10 males), whose ages ranged from 56 to 82 years (mean age 72 years). The symptom- and sign-positive spinal segment was identified by MRI. The time between onset of symptoms and surgical intervention ranged from 2 days to 1 year. 62 segments (36 thoracic, 26 lumbar) were treated in this cohort. The pain score estimated by Visual Analog Scale and activity degree were assessed immediately after operation and at 1-, 6-, and 12-month postoperative follow-up. Preoperative and postoperative anterior, midline vertebral heights in fractured vertebrae were measured on lateral radiographs to evaluate the effect of the procedure.</p><p><b>RESULTS</b>The method achieved a swift pain relief associated with an evidently increased weight-bearing ability. The pain score was reduced from 8.2 to 2.4 points. The anterior and midline vertebral heights in 62 fractured vertebral bodies increased up to 82.76%+/-26.84%, 88.82%+/-21.75% and the wedge decreased from 15 to 8 degrees. This effect persisted at least over a period of two years. The procedure did not induce narrowing of the spinal canal and no severe complications occurred.</p><p><b>CONCLUSIONS</b>Balloon kyphoplasty can result in immediate clinical improvement of mobility and pain relief, increase vertebral body height, and quickly return patient's activity. The short-term results are approved excellent, and the long-term results need further judgment.</p>

Selection of surgical procedure for the treatment of idiopathic scoliosis / 中华外科杂志

<p><b>OBJECTIVES</b>To discuss and evaluate the selection of surgical procedure for the treatment of idiopathic scoliosis according to the location and degree of the deformity.</p><p><b>METHODS</b>175 patients with idiopathic scoliosis underwent surgical treatment with correction and fusion. The patients were divided into four groups according to the location and degree of the deformity and four different procedures were used for each group. For each group, the blood loss, surgery time, correction rate, loss of correction at final follow up and complications were compared and analyzed.</p><p><b>RESULTS</b>All patients underwent surgery safely and no neurological complication occurred. The correction rate was 81% for Group I, 86% for Group II, 68% for Group III and 72% for Group IV. All patients were followed up at least 2 years and the average time was 38 months (24 approximately 52).</p><p><b>CONCLUSION</b>Proper selection of surgical procedure according to the location and degree of the scoliotic deformity, satisfactory results can be achieved in the treatment of idiopathic scoliosis.</p>
