A more than 20-year follow-up of pain and disability after anterior cervical decompression and fusion surgery for degenerative disc disease and comparisons between two surgical techniques.

Background: Follow-ups more than 20 years after neck surgery are extremely rare. No previous randomized studies have investigated differences in pain and disability more than 20 years after ACDF surgery using different techniques. The purpose of this study was to describe pain and functioning more than 20 years after anterior cervical decompression and fusion surgery, and to compare outcomes between the Cloward Procedure and the carbon fiber fusion cage (CIFC).

[The outcome of surgery for spinal stenosis in Swedish hospitals].

In a local and national quality control study based on Swespine the rate of satisfied patients and the rate of patients with reduced leg pain after surgery for spinal stenosis at Nacka Hospital was 70,5 % and 62,3 %, respectively, compared to 67,8 % and 60,5 % nationally. The rate was unchanged locally as well as nationally 2009-2019. Controlling for mix of patients by multiple regression analysis greatly reduced all differences between Swedish clinics with no statistically significant differences between them.

Clinical appearance and reliability in visual assessment after in situ fusion for high-grade isthmic spondylolisthesis.

Purpose: The current literature on clinical appearance after surgery for high-grade spondylolisthesis is inconclusive. The few long-term comparative studies on surgical reduction versus in situ fusion report contradictory findings concerning appearance-related issues. The purpose of the current study was to evaluate and quantify clinical appearance three decades after in situ fusion for high-grade isthmic spondylolisthesis.

The latitude hypothesis, vitamin D, and SARS-Co-V2.

The Latitude Hypothesis may explain seasonal variation in occurrence of flu and influenza-like illness, including SARS-CoV-2. We focus on one variable, vitamin D adequacy in the general population, and consider statistics of two sub-populations to propose a possible treatment to improve outcomes.Communicated by Ramaswamy H.

Adjacent segment disk degeneration three decades after fusion without attempted reduction for high-grade isthmic spondylolisthesis.

Study Design: Observational study.

Objectives: To evaluate adjacent segment disk degeneration (ASD) after fusion without attempted reduction at a young age for high-grade isthmic spondylolisthesis. The clinical relevance of ASD remains unclear.
