Revision surgery in distal junctional kyphosis.

Background: Opposed to proximal junctional kyphosis and proximal junctional failure, their distal equivalents, distal junctional kyphosis and failure (DJK/DJF) have received less attention in the literature. The aim of this article is to provide an overview of the problem of DJK-DJF in different clinical scenarios such as adolescent idiopathic scoliosis (AIS), Scheuermann's kyphosis (SK) and adult deformity surgery and to suggest a strategy for prevention and treatment.

Methods: A narrative review of the literature was conducted to identify the best evidence on the risk factors of the problem.

Does specialty matter? A survey on 176 Italian neurosurgeons and orthopedic spine surgeons confirms similar competency for common spinal conditions and supports multidisciplinary teams in comprehensive and complex spinal care.

Background Context: Spine surgery is a multifaceted subspeciality requiring a breadth of knowledge and skill from different branches of medicine for the treatment of pathologies varying from degenerative to deformity, oncological, and trauma.

Purpose: The aim of the study was to investigate the self-perceived competency of spine surgeons in relation to different types of spinal procedures.

Study Design/setting: This is a survey study.

Predictive Accuracy of Surgimap Surgical Planning for Sagittal Imbalance: A Cohort Study.

Unlabelled: MINI: Surgical planning in sagittal imbalance is recognized as a key step of treatment to ensure good clinical results. Surgimap is a reliable tool to predict satisfactory postoperative sagittal alignment. Setting by default pelvic tilt to 20° improves predictive value during surgical planning.

Fusion rate following extreme lateral lumbar interbody fusion.

Introduction: Lumbar fusion has been found to be a clinically effective procedure in adult patients. The lateral transpsoas approach allows for direct visualization of the intervertebral space, significant support of the vertebral anterior column, while avoiding the complications associated with the posterior procedures. The aim of this study is to determine the fusion rate of inter body fusion using computed tomography in patients treated by extreme lateral intersomatic fusion (XLIF) technique.

Corner osteotomy: a modified pedicle subtraction osteotomy for increased sagittal correction in the lumbar spine.

Introduction: Sagittal imbalance is a spine deformity with multifactorial etiology, associated with severe low back pain and gait disturbance that worsen deeply patients' quality of life. The amount of correction achievable through PSO is limited by the height of the resection of the posterior wall, causing a ceiling of segmental correction of 30-35°. The aim of this study is to describe and preliminarily evaluate the results of an alternative technique, corner osteotomy (CO), that can increase the amount of correction.

Pelvic parameters and global spine balance for spine degenerative disease: the importance of containing for the well being of content.

Purpose: Spinal deformities and pathologies of the spinopelvic junction are conditions affecting up to 60-70 % of the general aging population. In this review, we discuss the more recent knowledge on sagittal balance and its clinical implications.

Methods: Review of the literature regarding global spine balance.
