Primary sacral tumors are rare, representing fewer than 7% of spinal neoplasms. Following total sacrectomy, lumbopelvic instrumentation and fusion carries a high risk of non-union with no current consensus on fixation techniques to augment bony defects. We aim to describe the outcome of a reconstruction technique following total sacrectomy whereby lumbopelvic shortening is performed and the posterior pelvic ring is compressed to enable contact with the native L5 vertebra. ⋯ Primary lumbopelvic shortening represents an alternative local autograft reconstructive technique for management of large sacral defects following total sacrectomy. This technique obviates the additional morbidity and surgical cost associated with the use of previously described techniques.

Osteogenesis Imperfecta (OI) is a rare group of congenital genetic disorders that consists of a collagen synthesis defect. The most severe phenotype is type III OI. Characterized by progressive bone deformity, fragility and pulmonary impairment, causing significant morbidity and mortality. Also, multilevel spine deformities are observed, such as scoliosis. The literature on the pathophysiology of pulmonary impairment in relation to scoliosis in these patients is scarce and conflicting. This study aims to determine the prevalence of scoliosis and its relation to pulmonary function in type III OI patients. ⋯ Increasing thoracic scoliosis was correlated with decreased vital lung capacity in our study population of type III OI patients. High FEV1/FVC ratios found in this study population show restrictive lung pathophysiology. Therefore, it is plausible that the pulmonary impairment found in type III OI patients is a combined issue, partly associated to scoliosis and partly intrinsic to OI.

Review Meta Analysis
Meta-analysis of the efficacy of ketamine in postoperative pain control in adolescent idiopathic scoliosis patients undergoing spinal fusion.
In this meta-analysis, we aim to compare ketamine use versus a control group (saline solution) during induction of anesthesia in adolescent idiopathic scoliosis patients undergoing fusion surgery in terms of postoperative opioid consumption, pain control, and side effects. ⋯ The use intraoperative and postoperative continuous low doses of ketamine significantly reduces opioid use throughout the first 48 h in patients with AIS who undergo posterior spinal fusion.

Review Meta Analysis
Pulmonary function after thoracoplasty for adolescent idiopathic scoliosis: a systematic review and meta-analysis.
Thoracoplasty is a procedure which involves rib resection from the costovertebral junction to the apex of the rib hump deformity to address the cosmetic concerns of patients of scoliosis. There is conflicting literature on its effect on pulmonary function. The present meta-analysis was conducted to review and analyze the available literature and ascertain the effect of thoracoplasty on pulmonary function. ⋯ Overall decrease in pulmonary function after thoracoplasty necessitates the need of adequate preoperative pulmonary function to mitigate its effect on patient well-being. Use of a posterior approach for corrective surgery when thoracoplasty is planned might lead to better outcomes. More research is needed to study effect of preoperative Cobb's angle on pulmonary function.

Review Meta Analysis
Cervical immobilization in trauma patients: soft collars better than rigid collars? A systematic review and meta-analysis.
Rigid cervical spine following trauma immobilization is recommended to reduce neurological disability and provide spinal stability. Soft collars have been proposed as a good alternative because of the complications related to rigid collars. The purpose of this study was to perform a systematic review on soft and rigid collars in the prehospital management of cervical trauma. ⋯ II, Systematic Review.
