Abstract Background: The ideal surgical treatment for adult low-grade isthmic spondylolisthesis (ALIS) remains unknown. Isolated anterior and posterior procedures are popular but have resulted in equivocal outcomes, whereas combined anterior and posterior procedures are associated with higher complication rates despite improved outcome. Objective: To evaluate the clinical and radiographic outcomes following the treatment of ALIS using a 1-stage posterior approach with posterior decompression and posterolateral arthrodesis combined with an interbody fibular allograft strut. Methods: Fifteen patients underwent fusion by a single surgeon using our modified technique. Seven patients were female and 8 were male, with a mean age of 48 years. All patients were classified as Meyerding grade II slips and underwent a posterior approach only, a decompressive laminectomy, and a circumferential fusion with the use of a transsacral fibular allograft and a posterolateral instrumented fusion. Postoperative clinical and radiographic evaluations were performed at 3, 6, and 12 months, and then on an annual basis. Results: The average follow-up interval was 61 months. Three complications were seen: a single dural tear, an L5 radiculopathy secondary to a malpositioned pedicle screw, and one patient with urinary retention. The spines of all patients were determined to be fused by the 6-month postoperative visit. All patients returned to their normal activities of daily living. Significant improvements in the visual analog score were seen at all follow-up intervals. Conclusion: Transsacral interbody fibular allograft can be used successfully to supplement a posterolateral instrumented fusion in selected patients with low-grade ALIS.

Introduction: Cerebral vasospasm leading to delayed cerebral ischemia (DCI) is one of the most significant factors impacting functional outcome in patients diagnosed with non-traumatic subarachnoid hemorrhage (SAH). Effective treatment in this setting is lacking. We now report a single center retrospective cohort experience with intrathecal (IT) Nicardipine for this indication. Methods: All patients discharged between 2013-2017 diagnosed with non-traumatic SAH, either aneurysmal or idiopathic, were included in the analysis. Demographics, risk factors, clinical courses, radiological DCI, and functional outcomes were analyzed. Results: 1,085 patients were admitted with aneurysmal (n=796) or idiopathic (n=289) SAH. The mean age was 54.5±14.1 and 67.7% were women. Low grade hemorrhage (WFNS 1) was found in 42.4%, medium (WFNS 2-3) in 26.9%, and high grade (WFNS 4-5) in 30.7%. Cerebral vasospasm was diagnosed in 36.6% of the patients, and 85.4% of those received IT Nicardipine (n=339). Only 8.4% of all patients required angiography to treat vasospasm. TCD data was available for 159 patients who received IT Nicardipine. Treatment reduced mean velocities in all arteries within one day by 15.4% on average (p<0.01). This reduction was sustained for the duration of treatment. Nineteen patients (1.8%) suffered from bacterial ventriculitis, and no statistically significant correlation was noted between IT treatment and infection (OR 1.06 95%CI[0.42-2.7]). The incidence of radiological DCI, identified by blinded assement of imaging, was 9.4% and clinical DCI was 5.7%. In this cohort, 65.5% had a favorable functional outcome (mRS≤2) at 90 days. Conclusions: In a retrospective analysis, off-label IT Nicardipine is a safe and potentially effective treatment for cerebral vasospasm and prevention of the subsequent cerebral ischemia. Being the largest of its kind, this cohort could serve as a baseline for future clinical trial designs assessing IT Nicardipine safety and efficacy in a prospective, controlled fashion.
