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.

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).

Role of closed drain after multi-level posterior spinal surgery in adults: a randomised open-label superiority trial.

Purpose: To explore the role of closed suction drain in multi-level posterior spinal surgery.

Methods: We performed prospective, open-label, randomised control, superiority trial with parallel design and 1:1 allocation. A total of 161 patients undergoing posterior spinal surgery involving more than one motion segment at a dedicated spine surgery department were randomly allocated into "drain" or "no-drain" groups, based on which surgical drain was employed at the end of surgery.

Surgical Management of Myelomeningocele-Related Spinal Deformities.

Objective: To evaluate the optimal timing and type of surgical treatment of myelomeningocele (MMC)-related spinal deformities and long-term follow-up of surgical treatment.

Methods: We reviewed and presented clinical pictures, treatment strategies and results of 20 patients with MMC-related spinal deformities treated at our center between 2010 and 2017.

Results: The average patient age was 6.

Spectroscopic and theoretical study of the dimeric dicationic fullerene complex [(C70)2]2+ (Ti3Cl13)(-)2.

The first spectroscopic characterization of the dimeric dicationic fullerene complex [(C(70))(2)](2+)(Ti(3)Cl(13))(-)(2) is reported and supported by DFT calculations. The IR spectrum of the dimer is interpreted in terms of the normal modes of the pristine C(70), and the effects of charging C(70) and the intercage bond formation between C(70) units on the IR spectrum are discussed. Analysis of the vibrational spectrum of the anion, Ti(3)Cl(13)(-), is also provided.
