Serial elongation, derotation and flexion (EDF) casting under general anesthesia and neuromuscular blocking drugs improve outcome in patients with juvenile scoliosis: preliminary results.

Purpose: Juvenile scoliosis (JS), among different types of spinal deformity, remains still a challenge for orthopedic surgeons. Elongation, derotation and flexion (EDF) casting technique is a custom-made thoracolumbar cast based on a three-dimensional correction concept. The primary objective of the present study was to measure changes on plain radiographs of patients with JS treated with EDF plaster technique.

Dorsal arthrodesis in prepubertal New Zealand white rabbits followed to skeletal maturity: Effect on thoracic dimensions, spine growth and neural elements.

Background: Several studies have shown that severe spinal deformity and early arthrodesis can adversely affect the development of the spine and thorax by changing their shape and reducing their normal function. This article analyzes the consequences of posterior fusion on the growth of spine, thorax and neural elements in New Zealand white rabbits and compares with similar human data.

Materials And Methods: The first section of the article analyzes the consequences of T1-T6 dorsal arthrodesis on the growth of the spine, sternum, thorax volume and neural elements in 12 prepubertal female New Zealand white rabbits, through a study of CT scans and histology specimens.

Intranasal lidocaine plus naphazoline nitrate improves surgical conditions and perioperative analgesia in septorhinoplasty surgery.

Background: Septorhinoplasty is a traumatic procedure that is associated with epistaxis and postoperative pain. The primary objective of this randomized double-blind controlled trial was to determine whether intranasal 5% lidocaine plus naphazoline decreases postoperative pain and lessens the use of rescue analgesics.

Methods: After induction of general anesthesia and laryngeal topical anesthesia with 5% lidocaine, 28 adult patients, scheduled to undergo septorhinoplasty, were randomly assigned to one of two groups, either topical intranasal saline 20 ml (control group) or intranasal 5% lidocaine plus naphazoline solution 0.
