BACKGROUND: Context: Degenerative changes in the cervical spine occur in an age-dependent manner. As the U.S. population continues to age, the incidence of age-dependent, multi-level, degenerative cervical pathologies is expected to increase. Similarly, the average age of patients with cervical spondylotic myelopathy (CSM) will likely trend upward. Posterior cervical fusion (PCF) is often the treatment modality of choice in the management of multi-level cervical spine disease. Although outcomes following anterior cervical fusion for degenerative disease have been studied among older patients (aged 80 years and older), it is unknown if these results extend to octogenarian patients undergoing PCF for the surgical management of CSM...

BACKGROUND: There is ongoing controversy about the routine use of magnetic resonance imaging (MRI) preoperatively in patients with presumed idiopathic scoliosis (IS). Routine MRI can help identify possible causes for the deformity and detect anomalies which could complicate deformity surgery. However, routine MRI increases health care costs significantly and may reveal mild variations from normal without clinical relevance, that can still lead to anxiety and influence decision making...

Li Yao, Nikol Flynn
BACKGROUND CONTEXT: Advances in the development of biomaterials and stem cell therapy provide a promising approach to regenerating degenerated discs. The normal nucleus pulposus (NP) cells exhibit the similar phenotype as chondrocytes. Because dental pulp stem cells (DPSCs) can be differentiated into chondrogenic cells, the DPSCs and DPSCs-derived chondrogenic cells encapsulated in type I and type II collagen hydrogels can potentially be transplanted into degenerated nucleus pulposus (NP) to repair damaged tissue...

M Farshad, D E Bauer, C Wechsler, C Gerber, A Aichmair
BACKGROUND CONTEXT: There is a broad spectrum of complications during or after surgical procedures, with differing incidences reported in the published literature. Heterogeneity can be explained by the lack of an established evidence-based classification system for documentation and classification of complications in a standardized manner. PURPOSE: To identify predictive risk factors for peri- and early post-operative morbidities in spine surgeries of different complexities in a large cohort of consecutive patients...

BACKGROUND: Endoscopy is increasingly being used for minimal invasiveness and panoramic visualization, with unclear efficacy and safety among spinal intradural lesions. OBJECTIVE: To compare micro-endoscopic and pure-endoscopic surgery for spinal intradural lesions. METHODS: Spinal intradural lesions operated by us using endoscopic/access ports were categorized 'micro-endoscopic' (predominant microscope use), or 'pure-endoscopic' (standalone endoscopy) surgery, and studied with respect to clinico-radiological features, techniques, peri-operative course, histopathology, clinical and radiological outcome at minimum of 3 months...

BACKGROUND: Context: Achieving a successful spinal fusion requires the proper biologic and biomechanical environment. Optimizing load-sharing in the interbody space can enhance bone formation. For anterior cervical discectomy and fusion (ACDF), loading and motion are largely dictated by the stiffness of the plate which can facilitate a balance between stability and load-sharing. The advantages of load-sharing may be substantial for patients with comorbidities and in multi-level procedures where pseudarthrosis rates are significant...

BACKGROUND CONTEXT: Postoperative Urinary Retention (POUR) is a very common post-operative complication of all surgeries (5 - 70%) that may lead to complications such as urinary tract infection (UTI), bladder over-distention, autonomic dysregulation, and increased postoperative length of stay (LOS). Within the field of spine surgery, the reported incidence of POUR is highly variable (5.6 - 38%). Lack of clear stratification of surgical level, spinal pathology, and inadequate sample size is a major limitation of available studies concerning POUR following spine surgery that may lead to inconsistency in the incidence of POUR and the ability to model its occurrence and consequences...

INTRODUCTION: Relative value units (RVUs) are a compensation model based on the effort required to provide a procedure or service to a patient. Thus, procedures that are more complex and require greater technical skill and aftercare, such as multi-level spine surgery, should provide greater physician compensation. However, there is limited data comparing RVUs to operative time. Therefore, the purpose of this study was to compare mean: 1) operative times; 2) RVUs; and 3) RVU/minute between posterior segmental instrumentation of 3 to 6, 7 to 12, and ≥13 vertebral segments, and 4) perform annual cost difference analysis...

BACKGROUND CONTEXT: Dysphagia has been recognized as one of the most serious complications after occipitocervical fusion (OCF) and the difference between postoperative and preoperative O-C2 angle (dO-C2A) was proposed to be an indicator in predicting and preventing dysphagia. Therefore, in order to prevent postoperative dysphagia, previous studies recommend surgeons should correct the O-C2 angle (O-C2A) during surgery if the occipitocervical alignment was in an excessively flexed position...
