[Therapeutic and diagnostic classification of degenerative spondylolisthesis: validation and multiple-center inter-observer agreement].

Object: To evaluate inter- and intra-observer agreement of the proposed diagnostic and treatment classification of degenerative spondylolisthesis.

Material And Methods: The proposed diagnostic and treatment classification of degenerative spondylolisthesis was validated according to the GRRAS protocol. For this purpose, we retrospectively analyzed MRI, CT and spinal radiography data in 20 patients.

Optimizing sacral screw fixation in patients with caudal regression syndrome.

Purpose: The aim of this study is to evaluate and compare techniques and outcomes associated with two different technique of pelvic screw insertion in patients with caudal spine absence.

Methods: A cohort of patients with varying degrees of caudal structural regression, serves as the focal point of this investigation. Pelvic configurations were classified based on established criteria to facilitate comparative analysis.

Reliability and validity of the pediatric adaptation of the mJOA scale for evaluating cervical spine disorders.

Purpose: The study aimed to evaluate the validity and reliability of the pediatric adaptation of the Japanese Orthopedic Association (mJOA) scale in pediatric patients with various cervical spine pathologies.

Methods: Initial assessments were performed by a neurosurgeon, followed by an independent evaluation by a neurologist within 1-2 days to test inter-rater reliability. The same clinician assessed the same group of children using the adapted mJOA scale at different point in time (between 1 month and 1 year after the initial assessment) to test intra-rater reliability.

Segmental Spinal Aplasia: Anatomical Variations and Treatment Insights.

Study Design: Retrospective Cohort Study.

Objective: The study aimed to analyze anatomical variants of segmental spinal aplasia (SSA) and investigate factors influencing surgical treatment outcomes, with a specific focus on the incidence of complications.

Methods: The study focused on patients with SSA treated at a single medical center, with over two years of follow-up.

Cervicothoracic dislocation due to congenital and bone-dysplasia-related vertebral malformations.

Purpose: To evaluate the approaches to treatment of congenital and bone-dysplasia-related pediatric cervicothoracic dislocations and define the optimal treatment method.

Methods: The publications available in PubMed and Google Scholar data bases were selected following such criteria as the disease in question, pediatric age, the treatment description, and follow-up results. The paper also includes the descriptions of our own six cases of the cervicothoracic dislocations detected in children with different vertebral malformations.
