  • Post-operative nerve injuries after cervical spine surgery Although relatively rare, post-operative nerve injuries may occur after cervical spine procedures. The most common post-operative neural disorder is C5 nerve palsy. The risk factors for C5 nerve palsy are male gender, OPLL, and posterior cervical approaches. It generally presents with deltoid and/or biceps weakness, and may present immediately or several days after surgery. Treatment is generally conservative due to transient duration of symptoms, but evaluation of residual compression at C4-5 is essential.
  • Cervical disc arthroplasty: tips and tricks Cervical disc arthroplasty (CDA) is a powerful, motion-sparing treatment option for managing cervical radiculopathy or myelopathy. While CDA can be an excellent surgery for properly indicated patients, it is also less forgiving than cervical fusion. Optimally resolving patient symptoms while maintaining range of motion relies on near perfection in the surgical technique.
  • Restoration of Sagittal Balance in Spinal Deformity Surgery The prevalence of patients with adult spinal deformity (ASD) has been reported as high as 68%. ASD often leads to significant pain and disability. Recent emphasis has been placed on sagittal plane balance and restoring normal sagittal alignment with regards to the three dimensional deformity of ASD. Optimal sagittal alignment has been known to increase spinal biomechanical efficiency, reduce energy expenditure by maintaining a stable posture with improved load absorption, influence better bony union, and help to decelerate adjacent segment deterioration.
  • Evidence-based use of arthroplasty in cervical degenerative disc disease The objectives of this paper are to provide criteria for proper patient selection as well as to present a comprehensive literature review of the current evidence for CDA, including randomized studies, the most recent meta-analysis findings, and long-term follow-up clinical trials as well.
  • The "kickstand rod" technique for correction of coronal imbalance in patients with adult spinal deformity: initial case series The authors analyzed the records of 24 consecutive patients with pediatric and adult spinal deformity and CI treated between July 2015 and October 2017 with a long-segment fusion and a kickstand rod. For the kickstand rod technique, an iliac screw was placed on the ipsilateral side of the trunk shift and connected proximally through a side-by-side domino link to the thoracolumbar junction; this rod was distracted to promote coronal plane balancing.
  • No Clear Benefit of Chlorhexidine Use at Home Before Surgical Preparation Several studies have evaluated the efficacy of home use of chlorhexidine before surgery to reduce bacterial colonization. However, these studies have provided conflicting evidence about the potential efficacy of this strategy in decreasing bacterial loads and infection rates across surgical populations, and no prior study has analyzed the benefit of this intervention before spine surgery. We prospectively analyzed the effectiveness of chlorhexidine gluconate wipes for decreasing bacterial counts on the posterior neck.
  • Consortium of Orthopaedic Academic Traumatologists: A Model for Collaboration in Orthopaedic Surgery In March 2016, North American academic leaders with an interest in and commitment to the field of global orthopaedics met in Orlando, Florida, to gauge each institution's clinical, research, and educational programs in developing countries, establish the main limitations to participating in global health efforts, and assess areas of need for both the participating institutions and their international partners. After this inaugural meeting, a needs assessment survey was distributed to the group to better understand how to organize and unify the individual institutional global efforts.
  • The medicolegal landscape of spine surgery: how do surgeons fare? Because of the limited and confidential nature of most legal data, scarce literature is available to physicians about reasons for litigation in spine surgery. To optimally compensate patients while protecting physicians, further understanding of the medicolegal landscape is needed for high-risk procedures such as spine surgery. Based on these, surgeons can explore ways to better protect both their patients and themselves.
