Purpose: To analyze the predictors for second-stage posterior direct decompression (PDD) after lateral lumbar interbody fusion (LLIF) procedure.
Methods: We studied patients who underwent LLIF for degenerative lumbar spinal stenosis in the last five years, from July 2016 to June 2021. All surgical levels were grouped according to Schizas' central canal stenosis (CCS) classification, Pathria's facet joint degeneration (FJD) classification, Bartynski's lateral recess stenosis (LRS) classification, and Lee's foraminal stenosis (FS) classification.
Article Synopsis
- The repair of large bone defects presents a significant challenge for orthopedic surgeons, especially with the rise of an aging population and various chronic diseases.
- 3D bioprinting emerges as a promising technology that combines biomaterials and living cells, offering innovative solutions for tissue engineering by replacing or repairing damaged tissues and organs.
- Despite its potential, challenges such as biosafety, immunogenicity, and high costs must be addressed, alongside ongoing research to improve materials, scaffold manufacturing, vascularization, and cell viability in orthopedic applications.
