  • safety and efficacy of one stage Spinal osteotomy for severe and rigid congenital scoliosis associated with split Spinal Cord Malformation
    Spine, 2015
    Co-Authors: Bo Chen, Zhi Yuan, Jinghui Huang, Michael S Chang, Huan Li, Weizhou Yang
    Abstract:

    STUDY DESIGN: Retrospective clinical study. OBJECTIVE: To retrospectively evaluate the safety and efficacy of one-stage Spinal osteotomy in the treatment of severe and progressive congenital scoliosis (CS) associated with split Spinal Cord Malformation (SSCM). SUMMARY OF BACKGROUND DATA: For severe and rigid Spinal deformity, Spinal osteotomies are often advocated for correcting the deformity. However, the safety and efficacy of one-stage Spinal osteotomy in the treatment of severe and rigid CS with SSCM have been unclear thus far. METHODS: Patients were treated by one-stage Spinal osteotomy between September 2007 and June 2011 in our hospital. The clinical reCords were reviewed for demographic and radiographical data, operative time, intraoperative blood loss, blood transfusion, perioperative complications, and functional outcomes. RESULTS: There were 18 females and 11 males with an average age of 15.5 ± 3.6 years (range, 12-28 yr). Spinal Cord was longitudinally split by a bony spur in 11 patients (type I SSCM) and by a fibrous band in 18 patients (type II SSCM). Patients were observed for a minimum of 24 months after initial surgical treatment with an average follow-up of 43.0 ± 17.1 months (range 24-68 mo) from September 2007 to June 2013. The mean operative time and average blood loss of type ISSCM was significantly greater than those of type II SSCM (P < 0.05). The major curve was corrected from an average of 97.2°± 17.8° to 35.7°± 15.9°, a mean correction rate of 64.3% ± 11.0%. The average loss of correction at final follow-up was 2.9% for major curves. The overall complication rate was 24.1%, including transient neurological deterioration in 3 patients, cerebroSpinal fluid leakage in 2 patients, urinary tract infection in 1 patient and pleural rupture in 1 patient. CONCLUSION: Relative to multistage corrective surgery, one-stage Spinal osteotomy is effective for the correction of severe CS and SSCM without increasing the rate of surgical complications. However, surgical treatment of type I SSCM does require more operating time and blood loss. LEVEL OF EVIDENCE: 4.

    Abstract:

    Objective To analyze the safety and efficacy of one stage Spinal osteotomy for patients who had progressive severe and rigid congenital scoliosis (CS) associated with split Spinal Cord Malformation (SSCM).Methods A total of 24 patients underwent one stage Spinal osteotomies for severe and rigid CS associated with SSCM from September 2007 to November 2010 in our hospital.11 of these patients were males and 13 were females with an average age of 15.6±3.3 years (range,12-28 years).There were 11 patients with Type Ⅰ SSCM and 13 patients with Type Ⅱ SSCM.The mean major coronal curve ranged from 80° to 135° (average,93.4°±13.9°) and the coronal flexibility ranged from 4.9％ to 28.3％ (average,13.9％±7.1％).Before the corrective stage of surgery,bony spurs were resected in patients of Type Ⅰ SSCM,while nothing was done to the Type Ⅱ SSCM.Then,posterior osteotomy and fusion was performed to correct the Spinal deformity.Results All patients were followed up for a minimum of 24 months after initial surgical treatment with an average follow-up of 44.5±17.4 months (range,24-68 months).The average operation time was 554.7±118.4 min (range,395-895 min) and the average blood loss was 3 741.7±2 260.0 ml (range,1 000-9 600 ml).The average amount of blood transfusion was 3 711.3±2 059.4 ml (range,800-8 850 ml).The immediate postoperative correction rate was 47.2％ to 96.7％ (average,65.9％± 11.3％).At the final follow-up,the final correction rate was 62.7％± 12.0％ (range,40.7％-94.5％),with a correction loss of 3.0％±2.4％ (range,0.3％-8.9％).The overall major surgical complications rate was 25.0％ (6/24),including neurological deterioration in 3 patients (12.5％,3/24),cerebroSpinal fluid leakage in 2 patients (8.3％,2/24) and pleural rupture in 1 patients (4.2％,1/24).The neurological deterioration recovered to the preoperative neurological status at 1 week,3 months and 6 months postoperatively and improved at the final follow-up,compared with the preoperative status.Conclusion One stage Spinal osteotomy is safe and effective for severe and rigid CS with SSCM without increasing the complication rate.However,it results in longer operative time and more blood loss.

  • one stage three column osteotomy for the treatment of scoliosis with split Spinal Cord Malformation
    China Journal of Orthopaedics and Traumatology, 2020
    Co-Authors: Xinhao Wang, Wei Zheng, Jianguang Chen, Jixian Miao, Fengchun Li
    Abstract:

    OBJECTIVE: To analyze the effectiveness and safety of one stage three column osteotomy in treatment of scoliosis with split Spinal Cord Malformation. METHODS: The clinical data of 41 patients with scoliosis and split Spinal Cord Malformation underwent one-stage three-column osteotomy from January 2015 to December 2017 were retrospectively analyzed. There were 17 males and 24 females with average age of (25.14±4.51) years old and the average weight of (65.14±9.11) kg. AcCording to the classification of longitudinal spina bifida, 15 cases of Pang typeⅠwere group A and 26 cases of Pang typeⅡwere group B. The general situations of two groups were reCorded ; preoperative and postoperative Cobb angle were observed and the correction rate of Cobb angle of coronal plane was calculated ; the coronal and sagittal torso offset distances were compared between two groups and the trunk balance was evaluated ; the complication of two groups was reCorded. RESULTS: All 41 patients were followed up for more than 12 months. The operation time, intraoperative blood loss, and perioperative blood transfusion volume in group A were (610.14±115.02) min, (4 001.12±1 014.33) ml, (3 951.14±1 021.55) ml, respectively, and group B were (520.12±101.14) min, (2 701.57±1 021.45) ml, (2 565.77±880.47) ml, the difference between the two groups was statistically significant (P 0.05). There was no significant difference in postoperative coronary Cobb angle and correction rate between two groups (P>0.05). Immediately after surgery and 12 months after surgery, there was no significant difference in the trunk displacement distance of coronal view and sagittal view between two groups (P>0.05). Six patients in group A had complications, which was higher than that in group B of 1 case (χ2=4.885, P< 0.05). CONCLUSION: One-stage three-column osteotomy in treatment of scoliosis with split Spinal Cord Malformation has high correction rate and good balance of the trunk. However, for patients with typeⅠsplit Spinal Cord Malformation, they will face longer operation time, more intraoperative bleeding volume, large amount of perioperative blood transfusion and higher risk of complications, and the safety is not as good as that of typeⅡpatients. Therefore, in the actual treatment of scoliosis, especially for those with typeⅠsplit Spinal Cord Malformation, a more reasonable surgical plan should be developed in combination with the actual situations of the patients, so as to improve the safety of the operation.
