Object Cervical spine osteotomies are powerful techniques to correct rigid cervical spine deformity. Many variations exist, however, and there is no current standardized system with which to describe and classify cervical osteotomies. This complicates the ability to compare outcomes across procedures and studies. The authors' objective was to establish a universal nomenclature for cervical spine osteotomies to provide a common language among spine surgeons. Methods A proposed nomenclature with 7 anatomical grades of increasing extent of bone/soft tissue resection and destabilization was designed. The highest grade of resection is termed the major osteotomy, and an approach modifier is used to denote the surgical approach(es), including anterior (A), posterior (P), anterior-posterior (AP), posterior-anterior (PA), anterior-posterior-anterior (APA), and posterior-anterior-posterior (PAP). For cases in which multiple grades of osteotomies were performed, the highest grade is termed the major osteotomy, and lower-grade osteotomies are termed minor osteotomies. The nomenclature was evaluated by 11 reviewers through 25 different radiographic clinical cases. The review was performed twice, separated by a minimum 1-week interval. Reliability was assessed using Fleiss kappa coefficients. Results The average intrarater reliability was classified as “almost perfect agreement” for the major osteotomy (0.89 [range 0.60–1.00]) and approach modifier (0.99 [0.95–1.00]); it was classified as “moderate agreement” for the minor osteotomy (0.73 [range 0.41–1.00]). The average interrater reliability for the 2 readings was the following: major osteotomy, 0.87 (“almost perfect agreement”); approach modifier, 0.99 (“almost perfect agreement”); and minor osteotomy, 0.55 (“moderate agreement”). Analysis of only major osteotomy plus approach modifier yielded a classification that was “almost perfect” with an average intrarater reliability of 0.90 (0.63–1.00) and an interrater reliability of 0.88 and 0.86 for the two reviews. Conclusions The proposed cervical spine osteotomy nomenclature provides the surgeon with a simple, standard description of the various cervical osteotomies. The reliability analysis demonstrated that this system is consistent and directly applicable. Future work will evaluate the relationship between this system and health-related quality of life metrics.

Objective. To analyze the results of surgical treatment of chronic infectious cervical spondylitis and literature data.Material and Methods. Design: retrospective monocentric cohort study for 2017–2020. The study included medical history and clinical and instrumental data of 25 patients who underwent 28 reconstructive surgeries on the suboccipital (n1 = 3) and subaxial (n2 = 25) spine. The average follow-up period was 1 year 2 months ± 4 months. Statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS), version 22.0.Results. The effect of the duration of the therapeutic pause (p = 0.043) and the T1 slope (T1S) (p = 0.022) on the intensity of vertebrogenic pain syndrome was established. When assessing the parameters of the sagittal balance a direct relationship between the age of patients and the value of cervical sagittal vertical axis (CSVA) (p = 0.035) was revealed, while CSVA (p = 0.514) and neck tilt angle (NTA) (p = 0.617) did not significantly affect the intensity of vertebral pain syndrome. The extent of vertebral destruction did not affect either the intensity of vertebral pain (p = 0.872) or the indices of the sagittal balance: CSVA (p = 0.116), T1S (p = 0.154), and NTA (p = 0.562). A significant predictor of postoperative complications is the level of comorbidity with an index of 7 or more (p = 0.027) according to the Charlson scale.Conclusion. The leading predictors of complications of surgical treatment of cervical infectious spondylitis are the Charlson comorbidity index (7 points or more) and the variant of anterior reconstruction (the use of a blocked extraspinal plate). The factors influencing the intensity of vertebrogenic pain syndrome in this pathology are the duration of the therapeutic pause and the magnitude of T1S compensation. Anterior reconstruction of the cervical spine in the presence of infectious spondylitis provides a correction of the sagittal balance parameters, with the possibility of long-term maintaining the achieved values.

Unilateral facet dislocation at the subaxial cervical spine (C3–7) in children younger than 8 years of age is rare. The authors describe a surgical approach for irreducible subaxial cervical unilateral facet dislocation (SCUFD) at C3–4 in a 5-year-old boy and present a literature review. A dorsal unilateral approach was applied, and a biodegradable plate was used for postreduction fixation without fusion after failed conservative treatment. There was complete resolution of symptoms and restored cervical stability. Two years after surgery, the patient had recovered range of motion in C3–4. In selected cases of cervical spine injury in young children, a biodegradable plate can maintain reduction until healing occurs, obviate the need to remove an implant, and recover the motion of the injured segment.
