Objective To explore some operative problems of correcting paralytic scoliosis(PS) by using vertebral pedicle screwsrods system. Methods From May 2000 to May 2005, 18 patients with PS were corrected by screwsrods system which were made of titanium alloy.There were 10 males and 8 females, aging from 11 to 26 years. The primary disease included poliomyelitis in 13 patients and myelodysplasia (MS) in 5 patients (2 cases for second correction) with scoliosis of an average 85° Cobb angle (55-125°). The pelvic obliquity was found in all patients with an average 24° angle (355°).Of the 18 patients,3 cases were given perioperative halo-pelvic traction, 2 cases were given vertebral wedge osteotomy and correction and fixation, the other patients were purely underwent the treatment of pedicle screwrods system implants. Fusion segment at operation ranged from 6 to 15 sections, applied screws the most was 16,the fewest was 6. Results There were no wound infections and neurologic complications, all wounds healed by the first intention. Allscoliosis obtained obvious correction (P＜0.001), the correction rate averaged 52.95% (44%-81%); the majority of lumbar kyphosis and pelvic obliquity were apparently corrected. The average clinical follow-up (16 cases) was 21 months(6-36 months),there was no implants failure. One patient with MS had a worse Cobb magnitude, the other patients had no curve progression (P＞0.05). Conclusion The use of vertebral pedicle screwsrods fixation to multiple vertebral bodys and short segment fusion for PS, the treatment method is reliable and the outcome is satisfactory. While performing the correcting operative procedures, the spinal, pelvic and lower extremity deformities and functions should be all considered as a whole.
ObjectiveTo observe the medium-term clinical and radiological outcomes of anterior release internal distraction in treatment of severe and rigid scoliosis. MethodsBetween March 2009 and March 2012, 26 patients with severe and rigid scoliosis were treated with anterior release, posterior internal distraction, and two stage posterior spinal fusion. There were 11 males and 15 females with an average age of 19.6 years (range, 14-25 years). The average disease duration was 13.6 years (range, 3-24 years). All cases were idiopathic scoliosis. Of 26 cases, 2 cases were rated as Lenke type I, 8 as type Ⅱ, 13 as type IV, 1 as type V, and 2 as type VI. The apical vertebrae located at T6 in 1 case, at T7 in 3 cases, at T8 in 7 cases, at T9 in 13 cases, and at T10 in 2 cases. The average 4 vertebral bodies were released by anterior approach, and average 14 vertebral bodies were fused after posterior surgery. Fourteen patients received 2 times distraction. Scoliosis Research Society-22 (SRS-22) questionnaire was used to access health-related quality of life. The radiological parameters were measured, including coronal plane Cobb angel of major curve, apical vertebral translation (AVT), C7 plumb line-center sacral vertical line (C7PL-CSVL), sagittal vertical axis (SVA), and thoracic kyphosis (TK) at pre-and post-operation. ResultsThe average total operation time was 592.7 minutes; the average total blood loss volume was 1 311.2 mL; and total hospitalization cost was (14.7±1.4)×104 yuan RMB. The coronal plane Cobb angle of major curve was (55.7±16.5)°, and the TK was (43.2±16.2)° after first distraction. The patients were followed up 2-5 years (mean, 3.8 years). Temporary dyspnea and pleural effusion occurred in 1 case respectively after distraction, and symptoms disappeared after symptomatic treatment. Screw loosening and pseudoarthrosis formation was observed in 1 case at 6 months after fusion, good recovery was achieved after revision. No infection or neurological complication was found. The coronal plane Cobb angel of major curve, TK, and AVT after fusion and at last follow-up were significantly lower than preoperative ones (P<0.05), but no significant difference was found between at post-fusion and last follow-up (P>0.05). There was no significant difference in C7PL-CSVL and SVA between at pre-and post-operation (P>0.05). At last follow-up, SRS-22 questionnaire scores were 4.32±0.42 for active degree, 4.54±0.58 for mental health, 3.97±0.76 for self-image, 4.09±0.64 for pain, and 4.03±0.83 for satisfaction degree. ConclusionAnterior release internal distraction can provide satisfactory correction results for severe and rigid scoliosis with higher safety and lower incidence of complication.
Adolescent idiopathic scoliosis refers to a three-dimensional spinal deformity or structural change that occurs in adolescence. The rotation of the vertebral body is greater than or equal to 10°. In order to avoid affecting the physical and mental health of patients, appropriate intervention and treatment of adolescent idiopathic scoliosis should be carried out as soon as possible. Based on the summary of non-surgical treatment of adolescent idiopathic scoliosis at home and abroad, this paper systematically introduces the mainstream early non-surgical treatment of adolescent idiopathic scoliosis, including observation and follow-up, electrical stimulation therapy, Chinese traditional chiropractic techniques, massage and manual reduction, functional training and exercise therapy, traction therapy and brace therapy, in order to provide a reference for the possible treatment research direction of adolescent idiopathic scoliosis in the future.
ObjectiveTo summarize the progress of the surgical selection of fusion levels for degenerative scoliosis. MethodsThe domestic and foreign related literature about degenerative scoliosis, including clinical features, classification, surgical treatment, and the fused segment, was summarized. ResultsDegenerative scoliosis is very complicated. Short segment fusion and long segment fusion are the main surgical types. The long segment fusion is better in terms of reconstructing the stability of spine; however, it has more related complications. The short segment fusion has been used widely in clinical, but it causes degenerative disease easily. W/AL value can be used to direct the selection of short or long segment fusion for degenerative scoliosis. ConclusionThe key to success surgery is choosing reasonable fused segment. Now there is no unified selection standard. With more knowledge about degenerative scoliosis, greater development can be expected in the future.

Congenital scoliosis is the presence of a sideways curvature of the spine caused by the failure of normal vertebral development. Congenital scoliosis is usually progressive, and surgical treatment is crucial for the treatment of congenital scoliosis. Surgical treatments of congenital scoliosis mainly include simple fusion surgery, hemivertebrae excision, growing rods technique, and vertical expandable prosthetic titanium rib. However, there is no uniform standard for the selection of surgical techniques and surgical timing. This article reviews the progress of different surgical treatments for congenital scoliosis, introduces the classification of congenital scoliosis, and clarifies the timing, pros and cons of different surgical techniques, aiming to provide a reference for the development of individualized optimal surgical plans for patients with congenital scoliosis.
