Background:We assess Google Glass (“Glass”) in improving postoperative review (“debriefing”) and augmenting education in Neurological Surgery at a tertiary academic medical center.Methods:This was a prospective study. Participants were patients of Neurological Surgery physicians at a Tertiary Care Level 1 Academic Trauma Center. Resident physicians received a pre-questionnaire immediately following surgery. Next, the resident and attending physicians debriefed by reviewing the Glass operative recording. Then, residents completed a 4-part post-questionnaire. Questions 1–3 assessed: (1) the residents’ comfort level with the procedure, (2) the quality of education provided by their superiors, and (3) their comfort level in repeating the operation. Question 4 assessed: (4) the perceived benefit of debriefing using Glass.Results:Twelve surveys were collected. Scores were based on a 5-point Likert scale, with a higher score corresponding to a more positive response. For Questions 1–3, the average pre- and post-questionnaire scores were 3.75 and 4.42, respectively (P <.05). For Question 4, the average post-questionnaire score was 4.63, suggesting that postoperative Glass review improved their technical understanding of the procedure.Conclusions:Glass significantly improved neurosurgery residents’ comfort level and quality of training, and provided a high fidelity, reliable, and modifiable tool that enhanced residents’ understanding, expertise, and educational experience. Of note, certain limitations such as variable battery life, variable image quality, and subpar compatibility with surgeon loupes must still be overcome for Glass to become a realistic addition to neurosurgical education.
The surgical repair of atlantoaxial instabilities (AAI) presents complex and unique challenges, originating from abnormalities and/or trauma within the junction regions of the C1-C2 atlas-axis, to surgeons. When this region is destabilized, surgical fusion becomes of key importance in order to prevent spinal cord injury. Several techniques can be utilized to provide for the adequate fusion of the atlantoaxial construct. Nevertheless, many individuals have less than ideal rates of fusion, below 35%-40%, which also involves the C2 nerve root being sacrificed. This suboptimal and unavoidable iatrogenic complication results in the elevated probability of complications typically composed of vertebral artery injury. This review is a retrospective analysis of 87 patients from Cedars Sinai Medical Center in Los Angeles, California, who had the C1-C2 surgical fusion procedure performed within the time frame from 2001 to 2008, with a mean follow-up period of three years. These patients had presented with typical AAI symptoms of fatigability, limited mobility, and clumsiness. Diagnosis of C1-C2 instability was documented via radiographic studies, typically utilizing computed tomography (CT) scans or x-rays. All patients had bilateral C1 lateral masses and C2 pedicle screws. In addition, the C1-C2 joint was accessed by retracting the C2 nerve root superiorly and exposing the joint by utilizing a high-speed burr. The cavity that is developed within the joint is packed with local autologous bone from the cephalad resection of the C2 laminae. Fusion of the C1-C2 joint was achieved in all patients and a final follow-up was conducted approximately three years postoperative. Of the 87 patients, two presented with occipital headaches resulting from the C1 screws impinging on the C2 nerve root. The issue was rectified by removing instrumentation in both patients after documenting complete fusion via radiographic studies, with complete resolution of symptoms. No vertebral artery or spinal cord injuries were reported as a result of the minor complication. Overall, we aim to describe a safe and reliable alternative technique to fuse C1-C2 instability by focusing on intra-articular arthrodesis complementing instrumentation fixation. This methodology is advantageous from a biomechanical standpoint secondary to axial loading, as well as the large surface area available for arthrodesis. Additionally, this technique does not involve the resection of the C2 nerve root, resulting in low risk for vertebral artery or spinal cord injury.
Traumatic brain injury (TBI) is a major public health problem worldwide that affects all age groups. In the United States alone, there are approximately 50,000 deaths from severe traumatic brain injuries each year. In most studies, about 40 % of severe TBI have associated traumatic intracerebral hemorrhages (tICHs). The surgical treatment of tICH is debated largely because of its invasive nature, particularly in reaching deep tICHs. tICHs have a clear contribution to mass effect and exacerbate cerebral edema and ICP because of the break-down products of hemorrhage. We introduce a modification of the Mi SPACE technique (Minimally Invasive Subcortical Parafascicular Transsulcal Access for Clot Evacuation) that is applicable to tICH. In brief, this technique utilizes a trans-sulcal, stereotactic-guided technique in which a specially designed cannula is used to introduce a 13.5-mm-diameter tube into the epicenter of the tICH. We identified eight tICHs that were treated entirely or in part with the modified Mi SPACE technique during the time period from August 15, 2014 to December 15, 2014. This modified technique was readily deployed safely and efficaciously with significant removal of the tICH as demonstrated by postoperative CT scans. The removal of tICH using this minimally invasive technique may help with the control of ICP and cerebral edema.
