Arthrodesis versus dynamic neutralization: A short/mid- and long-term retrospective evaluation in degenerative disk disease treatment.

Study Design: This was a retrospective comparative study.

Objectives: The aim of this study was to perform a clinical and radiological retrospective evaluation of the most used techniques for the lumbar degenerative disk disease (DDD) treatment: arthrodesis versus dynamic neutralization (DN)-Dynesys dynamic stabilization system.

Methods: The study included 58 consecutive patients affected by lumbar DDD, 28 treated with rigid stabilization and 30 with DN at our department between 2003 and 2013.

Posterior spinal fusion in patients with spinal muscular atrophy: a surgical technique to allow intrathecally inject nusinersen.

Background: Nusinersen, the recently approved medical therapy in the treatment of spinal muscular atrophy (SMA), has revolutionized the natural history of this disease. Until now, surgical treatment of scoliosis in SMA patients was an exclusion criterion for drug therapy. In fact, the bone graft positioned posteriorly during surgery, in order to obtain a solid fusion, prevented the lumbar puncture necessary for the intrathecal administration of the drug.

Case series of four complex spinal deformities: new frontiers in pre-operative planning.

Background And Aim: Osseous and medullar anomalies constitute a hard challenge for interpretation of complex vertebral deformities anatomy. To better frame these deformities three-Dimensional (3D) printing represents a new frontier in this field. The aim of this brief report is describing the use of 3D printed models for surgical planning in four complex vertebral deformity cases treatment.

Arthroscopic surgery or exercise therapy for degenerative meniscal lesions: a systematic review of systematic reviews.

Background: Arthroscopic partial meniscectomy (APM) is widely applied for the treatment of degenerative meniscal lesions in middle-aged patients; however, such injury is often associated with mild or moderate osteoarthritis and has been reported by MRI in asymptomatic knees. Previous studies suggested, in most patients, a lack of benefit of surgical approach over conservative treatment, yet many controversies remain in clinical practice. Our aims were to assess the functional and pain scores between exercise therapy and arthroscopic surgery for degenerative meniscal lesions and to evaluate the methodological quality of the most recent systematic reviews (SRs).
