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.

Association of spinal cord abnormalities with vertebral anomalies: an embryological perspective.

Purpose: To analyze the relationship between spinal cord and vertebral abnormalities from the point of view of embryology.

Methods: We analyzed the clinical and radiological data of 260 children with different types of spinal cord malformations in combination with vertebral abnormalities.

Results: Among 260 individuals, approximately 109 presented with open neural tube defects (ONTDs), 83 with split cord malformations (SCMs), and 83 with different types of spinal lipomas.

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.

An alternative way of C1 screwing: Supralaminar C1 lateral mass screws.

Study Design: This study involves literature review, technical note, and case series.

Objectives: The objectives were to analyze indications and contraindications, advantages, and disadvantages for C1 lateral mass screw (LMS) insertion above or partially above the arch, to descript technical features, and to give examples of the practical application of this technique and investigated its safety.

Methods: A literature review was carried out in English and Russian in PubMed, Google Scholar, and eLibrary databases.

Atlantoaxial dislocation due to os odontoideum in patients with Down's syndrome: literature review and case reports.

Purpose: To clarify etiology, clinical features, and diagnostic and treatment options of atlantoaxial dislocation (AAD) due to os odontoideum (OsO) in patients with Down's syndrome (DS).

Methods: We described and analyzed three clinical cases of AAD due to OsO in DS patients and reviewed descriptions of similar cases in the scientific sources.

Results: According to literature review, more than 80% of DS patients with odontoid ossicles had atlantoaxial instability (AAI).
