Abstract

Background: Microdiscectomy for patients with chronic lumbar radiculopathy refractory to conservative therapy has significantly better outcomes than continued nonoperative management. The North American Spine Society (NASS) outlined specific criteria to establish medical necessity for elective lumbar microdiscectomy. We hypothesized that insurance providers have substantial variability among one another and from the NASS guidelines. Methods: A cross-sectional analysis of US national and local insurance companies was conducted to assess policies on coverage recommendations for lumbar microdiscectomy. Insurers were selected based on their enrollment data and market share of direct written premiums. The top 4 national insurance providers and the top 3 state-specific providers in New Jersey, New York, and Pennsylvania were selected. Insurance coverage guidelines were accessed through a web-based search, provider account, or telephone call to the specific provider. If no policy was provided, it was documented as such. Preapproval criteria were entered as categorical variables and consolidated into 4 main categories: symptom criteria, examination criteria, imaging criteria, and conservative treatment. Results: The 13 selected insurers composed roughly 31% of the market share in the United States and approximately 82%, 62%, and 76% of the market share for New Jersey, New York, and Pennsylvania, respectively. Insurance descriptions of symptom criteria, imaging criteria, and the definition of conservative treatment had substantial differences as compared with those defined by NASS. Conclusion: Although a guideline to establish medical necessity was developed by NASS, many insurance companies have created their own guidelines, which have resulted in inconsistent management based on geographic location and selected provider. Clinical Relevance: Providers must be cognizant of the differing preapproval criteria needed for each in-network insurance company in order to provide effective and efficient care for patients with lumbar radiculopathy. Level of Evidence: 5 Lumbar Spine. [ABSTRACT FROM AUTHOR]

Abstract

Study Design: Retrospective cohort study Objectives: The purpose of this study is to compare patient-reported outcome measures (PROMs) for patients undergoing one-to three-level lumbar fusion using robotically assisted vs freehand pedicle screw placement. Methods: Patients who underwent either robotically assisted or freehand pedicle screw placement for one-to three-level lumbar fusion surgery from January 1, 2014 to August 31, 2020 at a single academic institution were identified. Propensity score matching was performed based on demographic variables. Clinical and surgical outcomes were compared between groups. Recovery Ratios (RR) and the proportion of patients achieving the minimally clinically important difference (%MCID) were calculated for Oswestry Disability Index, PCS-12, MCS-12, VAS Back, and VAS Leg at 1 year. Surgical outcomes included complication and revision rates. Results: A total of 262 patients were included in the study (85 robotic and 177 freehand). No significant differences were found in ΔPROM scores, RR, or MCID between patients who underwent robotically assisted vs freehand screw placement. The rates of revision (1.70% freehand vs 1.18% robotic, P = 1.000) and complications (.57% freehand vs 1.18% robotic, P =.546) were not found to be statically different between the 2 groups. Controlling for demographic factors, procedure type (robotic vs freehand) did not emerge as a significant predictor of ΔPROM scores on multivariate linear regression analysis. Conclusions: Robotically assisted pedicle screw placement did not result in significantly improved clinical or surgical outcomes compared to conventional freehand screw placement for patients undergoing one-to three-level lumbar fusion.

Abstract

Study Design: This study is a retrospective case control. Objectives: This study aims to determine whether cervical degenerative spondylolisthesis (DS) is associated with increased baseline neck/arm pain and inferior health quality states compared to a similar population without DS. Methods: Patient demographics, pre-operative radiographs, and baseline PROMs were reviewed for 315 patients undergoing anterior cervical decompression and fusion (ACDF) with at least 1 year of follow-up. Patients were categorized based on the presence (S) or absence of a spondylolisthesis (NS). Statistically significant variables were further explored using multiple linear regression analysis. Results: 49/242 (20%) patients were diagnosed with DS, most commonly at the C4–5 level (27/49). The S group was significantly older than the NS group (58.0 ± 10.7 vs 51.9 ± 9.81, P =.001), but otherwise, no demographic differences were identified. Although a higher degree of C2 slope was found among the S cohort (22.5 ± 8.63 vs 19.8 ± 7.78, P =.044), no differences were identified in terms of preoperative visual analogue scale (VAS) neck pain or NDI. In the univariate analysis, the NS group had significantly increased VAS arm pain relative to the S group (4.93 ± 3.16 vs 3.86 ± 3.30, P =.045), which was no longer significant in the multivariate analysis. Conclusions: Although previous reports have suggested an association between cervical DS and neck pain, we could not associate the presence of DS with increased baseline neck or arm pain. Instead, DS appears to be a relatively frequent (20% in this series) age-related condition reflecting radiographic, rather than necessarily clinical, disease. [ABSTRACT FROM AUTHOR]
