Study Design: Retrospective review.
Objective: To evaluate how preoperative disability influences patient-reported outcomes (PROs) following primary surgical intervention for cervical herniated disc.
Summary Of Background Data: The effect of baseline disability has been evaluated for various spinal surgeries, but not specifically for primary cervical herniated disc.
Background: As lateral lumbar interbody fusions (LLIF) are increasingly performed, our understanding of postoperative clinical trajectories is important in informing preoperative patient expectations. While minimum clinically important difference (MCID) rates are widely utilized in spine surgery literature, there is less published on how long it takes for patients to achieve MCID following LLIF.
Objective: To evaluate the length of time it takes for patients to report MCID achievement for back pain, leg pain, disability, and physical function and evaluate predictors of time to achieve MCID.
Purpose: To evaluate the influence of preoperative VR-12 physical component scores (PCS) on outcomes following cervical disc replacement (CDR).
Methods: Patients undergoing elective CDR were retrospectively identified. Patient-reported outcomes (PROs) of interest included VR-12 PCS/VR-12 Mental Component Score (MCS)/9-Item Patient Health Questionnaire (PHQ-9)/Short Form-12 (SF-12) PCS and MCS/Patient-Reported Outcome Measurement Information System-Physical Function (PROMIS-PF)/Visual Analog Scale-Neck Pain (VAS-NP)/VAS-Arm Pain (VAS-AP)/Neck Disability Index (NDI).
Background: Prior literature has examined predictors of length of stay (LOS) for lumbar fusion broadly, grouping multiple surgical approaches into one sample. Evaluating minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) specifically can reduce variability introduced by other approaches to effectively identify predictors of LOS. The purpose of this study is to evaluate preoperative predictors of extended LOS in patients undergoing MIS-TLIF.

Objective: To examine the effect of preoperative motor weakness on clinical outcomes in patients undergoing cervical disk replacement (CDR).
Summary Of Background Data: Studies examining the effect of preoperative motor weakness on postoperative clinical outcomes in CDR are limited.
Article Synopsis
- - The study aimed to analyze how preoperative pain and disability affect patient-reported outcomes after minimally invasive lumbar fusion surgery for degenerative spondylolisthesis, focusing on symptom severity classifications: Mild, Moderate, and Severe.
- - A total of 177 patients were examined, revealing that those in the Severe group experienced the highest levels of postoperative pain and the worst pre- and post-operative outcomes, while all groups saw improvements over time.
- - The findings indicated that patients with more severe preoperative symptoms had greater improvements and better rates of achieving clinically significant outcomes compared to those with milder symptoms.
Study Design: Retrospective Review.
Objective: Evaluate the influence of the 12-Item veterans Rand (VR-12) physical component score (PCS) on patient-reported outcome measures (PROMs) in an outpatient lumbar decompression (LD) cohort.
Summary Of Background Data: The influence of baseline VR-12 PCS on postoperative clinical outcomes has not been evaluated in patients undergoing outpatient LD.
Study Design: Retrospective review.
Objective: To evaluate mental health influence on minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) patients.
Summary Of Background Data: Poor mental health has been postulated to indicate inferior patient perceptions of surgical outcomes in spine literature.
Background And Objectives: Severe facet arthropathy is generally a contraindication to undergoing cervical disc replacement (CDR) due to associated instability and potentially limited improvement in neck pain caused by arthropathy. This study evaluates the influence of facet arthropathy on radiographic/early clinical outcomes after CDR.
Methods: One/two-level CDR patients from a single surgeon's prospectively maintained database created 2 cohorts based on facet arthropathy: grade 0-1 or 2-3 (milder/moderate arthropathy).
Article Synopsis
- This study focuses on how preoperative motor weakness (MW) influences Patient-Reported Outcome Measures (PROMs) in patients undergoing lateral lumbar interbody fusion (LLIF).
- It includes data from 214 patients, with 149 experiencing MW, and analyzes various outcomes like physical function, pain levels, and quality of life before and after surgery.
- The findings indicate that while there were some demographic and perioperative differences between patients with and without MW, MW did not have a significant impact on overall PROM outcomes or minimum clinically important differences, except for one measure related to disability scores.
No study has examined the prognostic value of the Veterans RAND-12 (VR-12) Mental Component Score (MCS) on postoperative outcomes in minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) patients. This study examines the effect of preoperative VR-12 MCS on postoperative patient-reported outcome measures (PROMs) in MIS-TLIF patients. Patients were separated into 2 cohorts: VR-12 MCS < 50 and VR-12 MCS ≥ 50.

Comparison between anterior cervical diskectomy and fusion (ACDF) versus cervical disk arthroplasty (CDA) in this at-risk population has not yet been conducted.
Methods: Patients undergoing ACDF or CDA for DH with a PSD > 180 days were selected.
No study has evaluated the preoperative impact of Veterans RAND-12 Physical Composite Score (VR-12 PCS) on anterior lumbar interbody fusion (ALIF) patients. This study examines its influence on physical function, mental health, pain, and disability outcomes. Two cohorts of ALIF patients with preoperative VR-12 PCS scores were formed using a single-surgeon registry: VR-12 PCS < 30 and VR-12 PCS ≥ 30.

- Little research has explored how short-term postoperative patient-reported outcomes (PROs) predict long-term outcomes after lumbar decompression (LD), prompting a study to evaluate this relationship over two years.
- The study analyzed data from 277 patients, focusing on various PRO measures, such as pain scales and disability indexes, assessed at multiple time points, including 6 weeks, 6 months, 1 year, and 2 years post-surgery.
- Findings showed that 6-week PROs are strong predictors for outcomes at 6 months, with certain measures remaining predictive through 1 or even 2 years, aiding in understanding patient recovery trajectories and setting expectations.
The influence of Charlson Comorbidity Index (CCI) burden on Patient-Reported Outcomes Measurement Information System (PROMIS) outcomes following lumbar decompression (LD) is limited. The objective of this study is to evaluate CCI burden impact on PROMIS outcomes. Retrospective review of elective LD excluding revision or surgeries for infectious, malignant, or traumatic reasons.

Methods: DS patients who underwent surgical intervention were retrospectively identified from a single-surgeon spine registry. Cohorts based on Oswestry Disability Index (ODI) < 41 (milder disability) and ≥ 41 (severe disability) were created.
Objective: To evaluate the effect of Veterans RAND 12-item health survey mental composite score (VR-12 MCS) on postoperative patient-reported outcome measures (PROMs) after undergoing lateral lumbar interbody fusion.
Methods: Retrospective data from a single-surgeon database created 2 cohorts: patients with VR-12 MCS ≥ 50 or VR-12 MCS < 50. Preoperative, 6-week, and final follow-up (FF)- PROMs including VR-12 MCS/physical composite score (PCS), 12-item Short Form health survey (SF-12) MCS/PCS, Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS-PF), Patient Health Questionnaire-9 (PHQ-9), visual analogue scale (VAS)-back/leg pain (VAS-BP/LP), and Oswestry Disability Index (ODI) were collected.
Study Design: Retrospective review.
Objective: To assess the impact of Body Mass Index (BMI) on patient-reported outcome measures (PROMs) after cervical disc replacement (CDR).
Background: BMI may affect PROMs after spine surgery.
Study Design: Retrospective cohort study.
Objective: To assess the impact of preoperative symptom duration (PSD) on patient-reported outcome measures (PROMs) after minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) for degenerative spondylolisthesis (DSpond).
Background: A prolonged duration of preoperative symptoms may implicate inferior long-term outcomes postsurgery.
Article Synopsis
- The article talks about using antibiotics correctly during spine surgery to prevent infections and treat them.
- It suggests hospitals need to work together to choose the right antibiotics, how much to use, and how long to give them to help fight against antibiotic resistance.
- Lastly, the article encourages more research to find better ways to prevent and treat infections in spine surgery.
Objective: To determine prognostic value of preoperative Veterans RAND 12-Item Health Survey (VR-12) physical composite score (PCS) on outcomes in patients undergoing anterior cervical discectomy and fusion (ACDF).
Methods: ACDF patients with preoperative VR-12 PCS formed 2 cohorts: VR-12 PCS <35 and VR-12 PCS ≥35. The following patient-reported outcome measures (PROMs) were gathered preoperatively and postoperatively up to 2 years: VR-12 mental composite score (MCS)/PCS, Neck Disability Index (NDI), Patient-Reported Outcomes Measurement Information System (PROMIS) PF, 9-Item Patient Health Questionnaire (PHQ-9), visual analog scale (VAS) neck/arm pain, and 12-Item Short Form Health Survey (SF-12) PCS/MCS.
