Cement augmentation techniques are standard treatments for osteoporotic vertebral fractures. Compared with vertebroplasty, kyphoplasty is associated with lower rates of cement leak and better deformity correction; however, posterior wall fractures are relative, but not absolute; contraindications for both techniques and hence treatment practices vary among spine centers. ⋯ Balloon kyphoplasty is a viable option for the treatment of osteoporotic vertebral fractures even with posterior wall involvement.

Traumatic spinal injuries are often associated with both long-term disability, higher frequency of hospital readmissions, and high medical costs for individuals of all ages. Age differences in terms of injury profile and health outcomes among those who sustain a spinal cord injury have been identified. However, factors that may influence health outcomes among those with a spinal injury have not been extensively examined at a population level. ⋯ Spinal injury represents a substantial cost and results in debilitating injuries, particularly for older individuals. Spinal injury prevention efforts for older people should focus on the implementation of fall injury prevention, whereas for younger individuals, prevention measures should target road safety.

Research shows the progression of ossification of the posterior longitudinal ligament (OPLL) following decompressive surgery for cervical myelopathy, particularly in cases presenting with continuous or mixed radiographic types. To date, no study has investigated OPLL progression within each motion segment. ⋯ Type 2 or 3 disc involvement and segmental ROM>5° were risk factors for OPLL progression. Classification of cervical OPLL according to disc involvement may help predict OPLL progression following laminoplasty. Close follow-up is warranted in cases of type 2 or 3 with greater segmental motion.

Fusion typically consists of joint preparation, grafting, and rigid fixation. Fusion has been successfully used to treat symptomatic disruptions of the sacroiliac joint (SIJ) and degenerative sacroiliitis using purpose-specific, threaded implants. The biomechanical performance of these systems is important but has not been studied. ⋯ Fixation with two threaded rods significantly reduces SIJ motion even in the presence of joint preparation and after initial loading. The location of the secondary 8.5-mm implant does not affect construct performance. Low bone density significantly affects fixation and should be considered when planning fusion constructs. Findings should be interpreted in the context of ongoing clinical studies.

The Rothman Index (RI) is a comprehensive rating of overall patient condition in the hospital setting. It is used at many medical centers and calculated based on vital signs, laboratory values, and nursing assessments in the electronic medical record. Previous research has demonstrated an association with adverse events, readmission, and mortality in other fields, but it has not been investigated in spine surgery. ⋯ The RI is a tool that can be used to predict postdischarge adverse events after elective spine surgery that adds value to commonly used indices such as patient demographics and ASA. It is found that this can help physicians identify high-risk patients before discharge and should be able to better inform clinical decisions.
