Comparative Study
Mini-thoracotomy or thoracoscopic treatment for medially located thoracic herniated disc?
A retrospective cohort study. ⋯ The mini-TTA has some theoretical advantages over a thoracoscopy. It is also a minimally invasive approach. The thoracoscopy has a steep learning curve, whereas the mini-TTA is simple to apply. Classic microsurgical bimanual techniques can be used.

Retrospective comparison study of patients who had a delayed infection following a posterior spinal fusion and instrumentation (PSFI) for adolescent idiopathic scoliosis (AIS). ⋯ The occurrence of a delayed infection is most likely multifactorial and is related to a positive past medical history and the use of blood transfusions. Postoperative use of a drain may be important to avoid delayed infection.

A prospective study using computed tomography (CT) scans. ⋯ The safety zone was wider at the distal level (C5-C6, C6-C7) than at the proximal level (C3-C4, C4-C5). The safest needle entry point should be between the pushing point of the airway and the pulsating point of the carotid artery. In addition, the needle should be approached toward the center of the disc. A percutaneous cervical approach allows a low risk of pharyngoesophageal structure injury and is considered a safe diagnostic technique in dynamic imaging studies.

Matched cohort comparison. ⋯ In long spinal arthrodesis for complex adult spinal deformity surgery, aprotinin does reduce intraoperative blood loss, but may increase the risk of acute renal failure, especially in women over the age of 60.

Clinical study. ⋯ The oblique corpectomy is a surgical option in patients with asymptomatic OALL in the setting of progressive myelopathy due to OPLL with intrinsic stability as a result of their OALL. This technique avoids a multilevel central corpectomy that is associated with significant instability often requiring reconstructive procedures.
