Freehand technique for C2 pedicle and pars screw placement: is it safe?
During placement of C2 pedicle and pars screws, intraoperative fluoroscopy is used so that neurovascular complications can be avoided, and screws can be placed in the proper position. However, this method is time consuming and increases radiation exposure. Furthermore, it does not guarantee a completely safe and accurate screw placement. ⋯ Although even in experienced hands up to 23% of C2 pedicle screws and 11% of C2 pars screws placed using a freehand technique without guidance may be malpositioned, a clear majority of malpositioned screws demonstrated a low-grade breach, and only 2 of 198 patients (1%) experienced complications related to screw placement.

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.

Aggressive (Enneking stage 3, S3) vertebral hemangiomas (VHs) are rare, which might require surgery. However, the choice of surgery for S3 VHs remains controversial because of the rarity of these lesions. ⋯ Our results suggest that posterior decompression effectively provides symptom relief in patients with aggressive (S3) VHs with severe spinal cord compression. Intraoperative vertebroplasty is a safe and effective method for minimizing blood loss during surgery, whereas adjuvant radiotherapy or vertebroplasty helps in minimizing recurrence after decompression.

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.

Increasing bone ongrowth and ingrowth of polyether ether ketone (PEEK) interbody fusion devices has the potential to improve clinical outcomes. ⋯ Micro-CT and histology demonstrated bone ongrowth to the surfaces coated with NM where the newly formed bone tracked along the thin titanium-coated surfaces. Polyether ether ketone surfaces presented the nonreactive fibrous tissue at the interface as previously reported in preclinical scenarios.
