Spine surgery is complicated by an incidence of 1% to 9% of surgical site infection (SSI). The most common organisms are gram-positive bacteria and are endogenous, that is are brought to the hospital by the patient. Efforts to improve safety have been focused on reducing SSI using a bundle approach. The bundle approach applies many quality improvement efforts and has been shown to reduce SSI in other surgical procedures. ⋯ Significant reduction of SSIs is possible, but requires a systems approach involving all stakeholders. There are many simple and low-cost components that can be adjusted to reduce SSIs. Systematic efforts including understanding of pathophysiology, prevention strategies, and system-wide quality improvement programs demonstrate significant reduction of SSI.

Surgery for spinal metastases remains the mainstay treatment for pain, instability, and neurological deterioration due to tumor infiltration of the spine. However, several new therapies are emerging which may improve outcomes further, and in some cases even replace the need for surgery. We now have a better understanding of which factors influence survival and quality of life after surgery, and this underpins the development and application of new treatments, and assessment of outcome. ⋯ New surgical techniques allow smaller, quicker, and safer operations with less blood loss, pain, and quicker recovery after surgery. Radiation treatments have also leapt forward with the greater accuracy and higher doses possible from intensity-modulated photon radiation, stereotactic body radiation treatment, proton beam therapy, or carbon ion treatment. Combined with more advanced materials for vertebral body stabilization, computer navigation systems, and robotics, more can be done at earlier or later stages of the spinal disease than was previously possible, resulting in more options and improved outcomes for patients.

Intervertebral disk (IVD) degeneration is a natural progression of the aging process. Degenerative disk disease (DDD) is a pathologic condition associated with IVD that has been associated with chronic back pain. There are a variety of different mechanisms of DDD (genetic, mechanical, exposure). ⋯ Several of these modalities have been attempted in human trials, with early outcomes having promising results. Further, increasing our understanding of the degenerative process is essential to the development of new therapeutic interventions and the optimization of existing treatment protocols. Despite limited data, biological therapies are a promising treatment modality for DDD that could impact our future management of low back pain.

Over the last several decades, significant advances have occurred in the assessment and management of spinal deformity. ⋯ It is ultimately through the reviewed and other recent and ongoing advances that care for patients with spinal deformity will continue to evolve, enabling better informed treatment decisions, more meaningful patient counseling, reduced complications, and achievement of desired clinical outcomes.

Management of spinal trauma is a complex and rapidly evolving field. To optimize patient treatment algorithms, an understanding of and appreciation for current controversies and advancing technologies in the field of spinal trauma is necessary. Therefore, members of the AOSpine Knowledge Forum Trauma initiative used a modified Delphi method to compile a list of controversial issues and emerging technologies in the field of spinal trauma, and a list of the 14 most relevant topics was generated. ⋯ In summary, despite recent advances, the field of spinal trauma has many ongoing points of controversy. We must continue to refine our ability to care for this patient population through education, research, and development. It is anticipated that the new AOSpine fracture classification system will assist with prospective research efforts.
