Comparative Study
Comparison of sacroiliac joint degeneration between patients with sagittal imbalance and lumbar spinal stenosis.
The purpose of this study was to compare the degeneration of sacroiliac joints (SIJs) between adult spinal deformity (ASD) patients with sagittal imbalance and an age- and sex-matched lumbar spinal stenosis (LSS) patients without sagittal imbalance. ⋯ ASD patients with sagittal imbalance demonstrated more severe SIJ degeneration compared to the age- and sex-matched LSS group. PI was significantly correlated with both SIJ degeneration and SVA only in the ASD group.

Most spinal metastases are detected late, and thus, the impact of treatment on the health-related quality of life (HRQOL) is an important consideration. This study investigated the HRQOL following surgery for spinal metastases. ⋯ This large prospective study showed that surgical treatment for spinal metastases significantly improved the HRQOL.

This in vitro biomechanical study compares residual lumbar range of motion (ROM) and rod strain after lumbopelvic instrumentation using 2 rods, 4 rods and interbody cages. ⋯ Double rods and interbody cages decrease residual ROM in FE and AT. Double rods seem efficient in limiting strain in principal rods. The use of single rods with cages at the lumbosacral junction increases strain at the first adjacent level without cage.

A major challenge in metastatic spinal disease is timely identification of patients. Left untreated, spinal metastases may lead to gross mechanical instability and/or neurological deficits, often requiring extensive invasive surgical treatment. The aim of this cohort study was to assess the correlation between delayed treatment of patients with spinal metastases and functional performance, quality of life and survival. ⋯ The results from the present study show delayed treatment of patients with symptomatic spinal metastases has both direct and indirect adverse consequences for functional performance status, quality of life and survival. Optimization of referral pattern may accelerate the time to surgical treatment, potentially leading to better quality of life and survival.

Dislocation is one of the remaining challenges after total hip arthroplasty. The spinopelvic mobility is considered to be the key to solve this problem and is of interest both to arthroplasty and spine surgeons. The purpose of this letter is to discuss the spinopelvic mobility and spinal stiffness described in the paper titled "Impact of spinal alignment and stiffness on impingement after total hip arthroplasty: a radiographic study of pre‑ and post‑operative spinopelvic alignment." by Hagiwara S, et al. METHODS: Examining the consistency between this paper and previously published papers on spinopelvic mobility. ⋯ The conclusions and titles are overstated from the results, but this paper is highly valuable in reminding spinal surgeons of the importance of spinopelvic alignment and mobility in THA.
