Early Postoperative Increase in Procollagen Type 1 N-Propeptide (P1NP) Predicts One-Year Pseudarthrosis Following Anterior Cervical Discectomy and Fusion

Francis Lovecchio, Annika Bay, Joshua Zhang, Luis Felipe Colón et autres

STUDY DESIGN: Prospective cohort study. OBJECTIVE: To evaluate whether bone turnover markers (BTMs) predict pseudarthrosis after cervical spine surgery. SUMMARY OF BACKGROUND DATA: Pseudarthrosis is a major reason for reoperation after ACDF. However, prediction of pseudarthrosis remains elusive. Patient-level factors have proven …

Latent profile analysis of multidimensional muscle profiles versus traditional sarcopenia metrics for capturing sagittal malalignment in adult spinal deformity: a retrospective study

Donghua Huang, Zhan Wang, Mihir S. Dekhne, Michael Jian-Wen Chen et autres

STUDY DESIGN: Retrospective cohort study. PURPOSE: Using latent profile analysis (LPA) to multidimensionally profile trunk muscles, we aimed to identify muscle phenotypes, compare LPA-based classification with sarcopenia definitions for explaining sagittal alignment, and examine malalignment patterns across LPA-derived subtypes. OVERVIEW OF LITERATURE: …

The Spine–Foot Connection: Investigating Compensatory Mechanisms in Degenerative Spine Disease Through Foot Deformity Patterns

Sereen Halayqeh, Austin C. Kaidi, Tomoyuki Asada, Quante Singleton et autres

Background and Objectives: In degenerative spine disease, compensatory mechanisms are activated to maintain upright posture, extending beyond the spine to involve the pelvis, lower limbs, and feet. These adaptations may be accompanied by differences in foot alignment, which could be associated with …
