Team management in complex posterior spinal surgery allows blood loss limitation.

Purpose: The objective is to analyse peri-operative blood loss (BL) and hidden blood loss (HBL) rates in spinal deformity complex cases surgery, with a focus on the strategies to prevent major bleeding.

Methods: We retrospectively analysed surgical and anaesthesiologic data of patients who had been operated for adolescent idiopathic scoliosis (AIS) or adult spinal deformities (ASD) with a minimum of five levels fused. A statistical comparison among AIS, ASD without a pedicle subtraction osteotomy (PSO) (ASD-PSO( -)) and ASD with PSO (ASD-PSO( +)) procedures was performed with a view to identifying patient- and/or surgical-related factors affecting peri-operative BL and HBL.

What determines immediate postoperative coronal balance and delayed global coronal balance after anterior spinal fusion for Lenke 5C curves?

Purpose: To determine the factors associated with 6-week postoperative global coronal balance and delayed global coronal balance at 2-year follow-up after anterior spinal fusion for Lenke 5C curves.

Methods: A total of 124 consecutive Lenke 5C curves with minimum 2-year follow-up was studied. Radiographic parameters were studied preoperatively, 6 weeks postoperatively, and 2 years postoperatively.

Ligamentum Flavum Cyst With Acute Onset Motor Deficit: A Literature Review and Case Series.

Background: Ligamentum flavum cysts have been rarely described in the literature and are one of the rare causes of neural compression and canal stenosis. Very few cases of their association with neurologic deficits are reported to date, and association with acute onset weakness is even rarer.

Clinical Presentation: We report our experience with 3 cases of ligamentum flavum cyst that presented with acute onset weakness and also present a comprehensive literature review on lumbar ligamentum flavum cysts reported to date.

Prediction of Final Body Height for Female Patients With Adolescent Idiopathic Scoliosis.

Study Design: Retrospective cohort study.

Objectives: To explore the possibility of predicting final body height at maturity based on associating parameters at the time of diagnosing adolescent idiopathic scoliosis (AIS), while examining the effect of curve magnitude and deterioration.

Methods: A total of 284 female patients with AIS (mean age 12.

Cauda equina syndrome: false-positive diagnosis of neurogenic bladder can be reduced by multichannel urodynamic study.

Background: The present consensus suggests urgent surgical decompression if clinical features of cauda equina syndrome (CES) are supported by MRI evidence of pressure on cauda equina. However, clinical diagnosis has a high false-positive rate and MRI is a poor indicator. Though urodynamic studies (UDS) provide objective information about the lower urinary tract symptoms experienced by patients including neurogenic bladder, its role in the diagnosis of CES is not established.

Role of lordotic rod contouring in thoracic myelopathy: a technical note.

Introduction: Decompressive surgery for thoracic myelopathy due to anterior pathology can be challenging. Direct decompression through anterior approaches is associated with approach-related complications, whereas anterior decompression through posterior approaches is technically demanding and may result in neurological deterioration. We present a simple and effective surgical technique of indirect decompression through lordotic rod contouring to reduce such complications.

Conservative Management for Late Presenting Dural Tears After Spine Surgery: An Institutional Experience and Literature Review.

Background: Symptoms and evidence of cerebrospinal fluid (CSF) leak after an uneventful intraoperative and immediate postoperative course are a rare entity in spine surgery. The literature is sparse on the description of such late presenting dural tears (LPDTs). They may need further admissions, wound management, and additional surgical procedures that add to the morbidity of the patient.
