Google's People Also Ask feature uses various machine learning algorithms to distill the most frequently asked questions and link users to potential answers. The aim of this study is to investigate the most frequently asked questions related to commonly performed spine surgeries. This is an observational study utilizing Google's People Also Ask feature. A variety of search terms were entered into Google for anterior cervical discectomy and fusion (ACDF), discectomy, and lumbar fusion. Frequently asked questions and linked websites were extracted. Questions were categorized by topic based on Rothwell's Classification system, and websites were categorized by type. Pearson's chi-squared and Student t tests were performed as appropriate. A total of 576 unique questions (181 ACDF, 148 discectomy, 309 lumbar fusion) were extracted with 372 unique websites and 177 domains. The most common website types were medical practice (41%), social media (22%), and academic (15%). The most popular question topics were specific activities & restrictions (22%), technical details (23%), and evaluation of surgery (17%). Questions related to technical details were more common in discectomy vs lumbar fusion (33% vs 24%, p=.03) and lumbar fusion vs ACDF (24% vs 14%, p=.01). Questions related to specific activities & restrictions were more common in ACDF vs discectomy (17% vs 8%, p=.02) and ACDF vs lumbar fusion (28% vs 19%, p=.016). Questions related to risks & complications were more common in ACDF vs lumbar fusion (10% vs 4%, p=.01). The most frequently asked questions on Google regarding spine surgery are related to technical details and activity restrictions. Surgeons may emphasize these domains in consultations and direct patients to reputable sources of further information. Much of the linked information provided originates from nonacademic and nongovernment sources (72%), with 22% from social media websites.

Understanding global body balance can optimize the postoperative course for patients undergoing spinal or lower limb surgical realignment. This observational cohort study aimed to characterize patients with reported imbalance and identify predictors. The CDC establishes a representative sample annually via the NHANES. All participants who said “yes” (Imbalanced) or “no” (Balanced) to the following question were identified from 1999–2004: “During the past 12 months, have you had dizziness, difficulty with balance or difficulty with falling?” Univariate analyses compared Imbalanced versus Balanced subjects and binary logistic regression modeling predicted for Imbalance. Of 9964 patients, imbalanced (26.5%) were older (65.4 vs. 60.6 years), with more females (60% vs. 48%). Imbalanced subjects reported higher rates of comorbidities, including osteoporosis (14.4% vs. 6.6%), arthritis (51.6% vs. 31.9%), and low back pain (54.4% vs 32.7%). Imbalanced patients had more difficulty with activities, including climbing 10 steps (43.8% vs. 21%) and stooping/crouching/kneeling (74.3% vs. 44.7%), and they needed greater time to walk 20 feet (9.5 vs. 7.1 s). Imbalanced subjects had significantly lower caloric and dietary intake. Regression revealed that difficulties using fingers to grasp small objects (OR: 1.73), female gender (OR: 1.43), difficulties with prolonged standing (OR: 1.29), difficulties stooping/crouching/kneeling (OR: 1.28), and increased time to walk 20 feet (OR: 1.06) were independent predictors of Imbalance (all p < 0.05). Imbalanced patients were found to have identifiable comorbidities and were detectable using simple functional assessments. Structured tests that assess dynamic functional status may be useful for preoperative optimization and risk-stratification for patients undergoing spinal or lower limb surgical realignment.

Systematic review and meta-analysis. To perform a comprehensive meta-analysis comparing clinical outcomes of uniportal versus biportal endoscopic spine surgery across decompression procedures in patients with lumbar degenerative disease (LDD). Uniportal endoscopic spine surgery has been a widely adopted minimally invasive technique, whereas biportal endoscopy has recently emerged as a promising alternative with potential advantages in surgical outcomes. A systematic review and meta-analysis of comparative studies was conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. PubMed, Embase, and Scopus databases were searched to identify relevant studies. Eleven studies encompassing 374 uniportal and 368 biportal patients were included. Outcomes analyzed were Oswestry Disability Index (ODI), Visual Analog Scale (VAS) scores for back and leg pain, complication rates, operative time, and length of hospital stay. Biportal endoscopic surgery was associated with a significantly lower ODI at 1-3 months and at final follow-up compared with uniportal surgery. However, uniportal discectomy demonstrated significantly shorter operative time and length of hospital stay than biportal discectomy. No significant differences were observed between approaches in terms of VAS scores, complication rates, or ODI at other time points. Both uniportal and biportal endoscopic spine surgeries yield comparable postoperative outcomes in LDD. Although biportal surgery showed a modest advantage in ODI improvement, it did not reach the minimal clinically important difference. Uniportal surgery demonstrated greater efficiency in terms of operative time and recovery, particularly for discectomy procedures.

» Lateral decubitus positioning is a nonanatomical position used for multiple orthopaedic procedures to obtain adequate surgical exposure. » Unique ophthalmologic, musculoskeletal, neurovascular, and hemodynamic complications may arise inadvertently from positioning. » Orthopaedic surgeons should be aware of the possible complications that may manifest from placing patients in the lateral decubitus position to adequately prevent and to properly manage them.
