Introduction: Increased fatty infiltration of the paraspinal muscles (PM) has been recognized as a sign of decreased muscle quality in patients with degenerative disc disease. However, whether fatty infiltration is a consequence of a neurogenic process due to spinal nerve root compression has not yet been determined.
Objective: To investigate the correlation between fatty infiltration of the paraspinal muscles (PM) and neurogenic remodeling of motor unit action potentials (MUAPs) in patients with lumbar radiculopathy.
Background: Navigation surgical systems have been widely used in spinal fusion to ensure accuracy and safety during pedicle screw insertion.
Methods: The research was performed under laboratory conditions, using stereotactic navigation, surgical instruments for spinal fusion, development of additional devices and software. During the experiments, all stages of the computed tomography-guided navigation system use were performed-preoperative preparation of patient data and planning to provide visual control of the navigation of surgical instruments during the insertion of screws.
Objectives: To conduct a systematic review and single-arm meta-analysis to evaluate and compare radiological indicators, as well as short-term and long-term outcomes, in patients with neurologically intact thoracolumbar burst fractures (TLBF) who underwent anterior fusion, combined anterior-posterior procedure, or short-segment pedicle screw fixation (PSF).
Methods: A systematic review following PRISMA guidelines was conducted. Inclusion criteria comprised articles published between 2004 and 2023, full-text availability in English, burst fractures without spinal cord or nerve root injuries at admission, short-segment PSF without fusion, anterior or combined fusion methods, patients aged 18 or older, and a minimum 12-month follow-up.
Objective: To conduct a systematic review of studies on various posterior pedicle screw fixation (PSF) methods used for treating neurologically intact thoracolumbar burst fractures and to identify the most effective and safe approaches.
Methods: We conducted a systematic review adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, with the study registered in PROSPERO (CRD42024531093). The inclusion criteria were: (1) publication dates from January 1, 2004, to December 31, 2023; (2) availability of full-text articles in English; (3) thoracolumbar burst fractures without neurological deficits; (4) patients aged over 18; (5) reports on treatment outcomes or complications; (6) a mean follow-up period of at least 12 months.
Short-term and long-term results of odontoid screw fixation in patients with Type II and rostral Type III dens fractures.

Article Synopsis
- - The study assessed the short-term and long-term outcomes of odontoid screw fixation (OSF) for Type II and rostral Type III odontoid fractures in patients over 15 years old, excluding those with certain other injuries and osteoporosis.
- - A total of 56 patients were analyzed for short-term results while 26 were evaluated for long-term outcomes, revealing a 95.7% bone fusion rate and noting that screw cut-out correlates with fragment displacement.
- - The research concluded that OSF is a reliable treatment for specific odontoid fractures, especially those with fragment displacement of 4 mm or less, showing overall favorable patient outcomes reflected in quality-of-life measures.
