These techniques were being alternative to the standard anterior approach with less morbidity and mortality. Patients and Methods: This study was performed between 2011 and 2014 on 100 patients with acute unstable thoracolumbar spine fractures which were divided into four groups: 30 patients underwent (TLIF), 28 patients underwent (PLIF), 28 patients underwent (PA) and 14 patients underwent (TPA). Neurological outcome, complications, operative times, kyphotic angle, vertebral height loss, spinal canal compromise, pulmonary functions, Denis pain and work scale, VAS score, ODI score, hospital stay, and estimated blood loss (EBL) were evaluated and compared in between the four groups. Results: There was a higher complication rate, increased EBL, and longer operative time with posteroanterior (PA) compared with PLIF, TLIF and (TPA). Patients undergoing PLIF, TLIF and TPA had a greater recovery of neurological function than those in whom PA were performed. Conclusion: TPA appeared to have more favorable results in improving the clinical and radiological outcome and no complications were reported apart from superficial wound infection which healed rapidly. The PLIF, TLIF and TPA appeared to have a comparable morbidity rate to PA. The different methods of anterior reconstruction from posterior approach are more favorable, applicable and convenient than PA approach.展开更多

The outcome of severely displaced supracondylar fracture of the humerus in children subjected to wide controversies in term of safety, functional and cosmetic outcome. Closed reduction and percutaneous pinning is now considered as the gold standard rule, but open reduction still applicable in certain cases where intraoperative imaging is not available, in comminuted lateral column fractures and uneducable fractures. Aim of the Study: To compare the outcome (functional and cosmetic) of anterior (Henry) approach with the posterior (Campbell) approach used in two groups of patients’ sustained displaced supracondylar fractures. Patients and Methods: This prospective study was performed on 48 pediatric patients who were been admitted to the Emergency Hospital in Sulaimani province sustained displaced supracondylar humeral fractures and treated during the period from the first of October 2009 to the thirty-one of January 2011. The study included 28 boys, 20 girls;their mean age was 7.5 years;their ages range 2 - 13 years. We used the modified Gartland classification to assess the fractures displacement and only Gartland type II B and III were included and managed operatively by open reduction and internal fixation with 2 crossed K-wires. Follow up continued for 6 months and the results finally assessed using Flynn’s criteria. Results: According to the criteria of Flynn et al., 20 patients (83.3%) treated by the anterior approach had excellent functional results while 4 patients (16.7%) had good functional results. While those treated by the posterior approach, 16 patients (66.6%) had excellent functional results, 6 patients (25%) had good results and 2 (8.3%) patients had fair outcome. Cosmetic results were excellent in 22 patients in the anterior approach group and 20 patients in the posterior approach group. Conclusion: Posterior Campbell approach is simpler than anterior Henry approach, but it creates additional soft tissue damage that can affect the circulatory status and hence possible osteonecrosis of the trochlea and a higher percentage of limitation in joint mobility. While the anterior approach is technically more demanding, but it gives better functional results.展开更多

However, its consequences can be severe. Because of the special anatomic location of the cervicothoracic junction, surgical treatment is difficult and rarely reported. The aim of this clinical study was to assess the effectiveness of combined anterior and posterior approaches for focal debridement, decompression, allografting and anterior instrumentation in the treatment of CJST in children. Methods Ten pediatric CJST patients underwent focal debridement and cord decompression through combined anterior and posterior approaches. Then an appropriate allograft and titanium plate were applied to reconstruct the spine. The patients were asked to wear head-neck-chest braces for six months and received regular anti-tubercular drugs therapy for 12 months. Results The patients were followed-up for an average of 26 months （range, 15-32 months）. There was no recurrent tuberculous infection. The bone grafts incorporated well and the instrumentation was stable. Cervical and thoracic kyphosis was successfully corrected from 40° （range, 30-52°） before the operation to 18° （range, 12-26°） post-operation. Neurological function was improved in all patients. Conclusions Combined anterior and posterior approaches for focal debridement, decompression, bone allografting and anterior instrumentation provided an effective means of treatment in children of CJST with a huge abscess in the posterior part of the vertebral body.展开更多
