ABSTRACT
STUDY DESIGN: Longitudinal cohort study. PURPOSE: To determine the effect of change in interspace height on fusion and postoperative neck pain. OVERVIEW OF LITERATURE: The optimal height of a cervical interbody device (cage) in anterior cervical discectomy and fusion (ACDF) is not well defined. In addition, the effect of interspace distraction on fusion and postoperative neck pain remains unclear. METHODS: We retrospectively reviewed the charts of consecutive patients who underwent one- or two-level ACDF using polyetheretherketone cages by multiple surgeons from January 2015 to June 2016. We excluded patients younger than 18 years old, patients who had prior surgery at the same level (s), those with two-stage procedures, and those with less than 3 months of followup. Fusion was determined using the "Song" criteria. Ordinal regression was used to determine predictors of fusion. Patient-reported outcomes (PRO) were analyzed. RESULTS: We identified 323 consecutive patients. Twenty-two patients met the exclusion criteria. A total of 435 operative levels were included in the 301 remaining patients. Interspace fusion did not significantly vary by increasing interspace height with fusion rates between 76.2% and 82.8% at a mean follow-up of 17.9±12.6 months. The effect of an increase in interspace height and neck pain PRO was available for 163 patients who underwent one-level ACDF at a mean follow-up period of 16.2±13.1 months. We found no significant difference in fusion rate or neck pain score with increasing interspace height from 1 to 8 mm. Ordinal regression demonstrated no significant predictors of fusion. CONCLUSIONS: Interspace distraction from 1 to 8 mm did not result in significantly different pseudarthrosis rates or postoperative neck pain.
ABSTRACT
BACKGROUND: Telemedicine refers to various modalities for remote care, including telephone calls, imaging review, and real-time video teleconferencing visits. Although it has not been widely used in outpatient neurosurgery settings, the COVID-19 (coronavirus disease 2019) pandemic has necessitated a broader adoption. Our goal is to show the level of patient satisfaction with their telemedicine care. METHODS: We prospectively studied consecutive telemedicine patients who scheduled outpatient neurosurgery visits from May 15 to June 8, 2020. Patients were seen by the surgeon via real-time video conferencing using Google Meet, and then completed a telemedicine satisfaction survey. Our primary outcome was telemedicine satisfaction scores. We compared satisfaction scores between new and established patients and between patients within and outside of a 15-mile radius of the nearest clinic location. Sensitivity analyses were performed to account for the nonrespondents. Descriptive and univariate analyses were performed. A P value of <0.05 was considered significant. RESULTS: Five-hundred and ninety patients completed a telemedicine visit during the study period. One patient from out of state was excluded. Three-hundred and ten patients (52.6%) responded. The average age was 60.9 ± 13.60 years; 59% were female, 20.6% were new patients; the average distance to the clinic was 28.03 ± 36.09 km (17.42 ± 22.43 miles). The mean overall satisfaction score was 6.32 ± 1.27. Subgroup analyses by new/established patient status and distance from their home to the clinic showed no significant difference in mean satisfaction scores between groups. CONCLUSIONS: Telemedicine provided a viable and satisfactory option for neurosurgical patients in the outpatient setting during the COVID-19 pandemic.
