Characteristics of Cervical Spine Motion in Different Types of Cervical Alignment: Kinematic MRI Study
Conclusion: Sagittal malalignment of the cervical spine affects all parts of the cervical motion complex. The global kyphotic alignment of subaxial cervical spine affects the kinematic properties of the occipito-atlanto-axial complex and upper thoracic spine to compensate for the alteration of cervical alignment. These differences are not seen in straight and segmental kyphosis. Level of Evidence: Level 3. (Source: Journal of Spinal Disorders and Techniques)

Hidden Blood Loss in Posterior Lumbar Fusion Surgery: An Analysis of Risk Factors
Conclusions: We conclude that a large amount of HBL may occur in patients who underwent PLF surgery for degenerative spine. In addition, significant hidden loss may have a correlation with postoperative mortality. Multilevel fused, surgical time, and fibrinogen level should be paid close attention when considering strategies of fluid infusion and blood transfusion.

The Influence of Geography, Time, and Payer Type on the Utilization of Bone Morphogenetic Protein (BMP) Between 2005 and 2015
Bone morphogenetic protein (BMP) is a critical compound for endochondral bone formation and is used as a bone graft substitute to promote spinal fusion and fracture healing. We sought to identify rate, type, and applications of use of BMP in spinal fusion surgery during 2005 to 2015. The Medicare 5% national sample (SAF5) database and the Humana Orthopaedics database (HORTHO) were searched for patients who underwent spinal fusion with BMP. Rate of use over time and influence of geographic region and payer type on utilization of BMP during 2005 to 2015 were analyzed. A total of 9879 and 12,598 patients were treated with BMP...

Efficacy of Conical Laminoplasty After Thoracic Laminectomy
Conclusions: Conical laminoplasty is particularly useful in a case in which T-saw laminoplasty cannot be performed due to tumor expansion in the canal and ossification of the ligamentum flavum. Conical laminoplasty also preserves the posterior elements, which reduces the risk of worsening of kyphosis postoperatively. (Source: Journal of Spinal Disorders and Techniques)

Thoracolumbar Burst Fractures
Thoracolumbar burst fractures are high-energy vertebral injuries, which commonly can be treated nonoperatively. Consideration of the injury pattern, extent of comminution, neurological status, and integrity of the posterior ligamentous complex may help determine whether operative management is appropriate. Several classification systems are contingent upon these factors to assist with clinical decision-making. A multitude of operative procedures have been shown to have good radiographic and clinical outcomes with extended follow-up, and treatment choice should be based on the individual’s clinical and radiographic pr...

Conclusions: Long-term outcomes, surgeon’s recommendation, and complication risk were the most important criteria identified by patients when choosing between open and MIS surgery. Patients also perceived MIS surgery to have advantages over open surgery with regard to postoperative pain, complication risk, recovery time, cost, and anesthesia requirement. Most patients seem to prefer a minimally invasive approach to their treatment. (Source: Journal of Spinal Disorders and Techniques)

Incidence and Risk Factors for Proximal Junctional Kyphosis: Results of a Multicentric Study of Adult Scoliosis
Conclusions: Increased age, as well as increased body mass index, is a risk factor for the development of PJK. The proximal extent of the construct is also shown to be a risk factor for PJK, but fusion to the sacrum is a risk factor only if fusion extends to the proximal TS. Moderate PJK was observed with undercorrection of the sagittal balance and severe PJKs with overcorrection of the sagittal balance. Level of Evidence: Level IV.

Microscope and Fiberscope-assisted Subarachnoid-Subarachnoid (S-S) Bypass: A Novel Surgical Technique to Reestablish Cerebrospinal Fluid Flow in Treating Dorsal Spinal Arachnoid Webs, Diagnosed by Cine-MRI
A “dorsal spinal arachnoid web” is the thickened arachnoid band on the surface of the spinal cord which disturbs the cerebrospinal fluid (CSF) flow, known as a rare cause of thoracic myelopathy. The ideal treatment is controversial because of the risk of readhesion after simple resection of the web. A subarachnoid-subarachnoid bypass is a method to reestablish CSF flow through a silicon tube between the cranial and caudal subarachnoid space.
