Cervical spondylolysis with spondylolisthesis is a complex abnormality involving the posterior elements of the cervical vertebra, and anterolisthesis of the same vertebra. Cervical spondylolysis is defined as a corticated cleft between the superior and inferior articular facets of the articular "pillar", the cervical equivalent of the pars intraarticularis in the lumbar spine. The typical radiological features of this condition are as follows: 1. Spondylolysis (a break in the "pillar" on one or both sides) 2. Spina bifida of dysplastic vertebra 3. Affection of posterior intervertebral joints (abnormal inclination of the superior and inferior articular facets of the affected bones may present) Recognition of this congenital disorder and its differentiation from traumatic injury is extremely important in patients who have a history of recent cervical trauma.

Kinematic status of Bryan and Mobi-C artificial cervical discs post cervical hybrid surgery: a retrospective study.
J Orthop Surg Res
December 2024
Dongzhimen Hospital Afliated to Beijing University of Chinese Medicine, Beijing, 100700, China.
Objective: To examine the mid-term efficacy and imaging results of using the Mobi-C and Bryan implants after cervical hybrid surgery for 2-level cervical spondylolisthesis, and to observe their postoperative changes and differences in the flexion-extension center of rotation (FE-COR) for the anterior cervical disc replacement (ACDR) segment.
Methods: Patients who underwent cervical hybrid surgery between June 2014 and June 2019 were included in this study. The mJOA, NDI, and VAS scores were used to assess clinical outcomes, and the FE-COR of the ACDR segment was measured.
Characteristics of Lumbar Pars Interarticularis and Pedicle Stress Injuries by Sport in 902 Pediatric and Adolescent Athletes: A Retrospective Study.
Am J Sports Med

Division of Sports Medicine, Department of Orthopedics and Sports Medicine, Boston Children's Hospital, Harvard Medical School, Boston, Massachusetts, USA.
Article Synopsis
- Research indicates a higher prevalence of upper lumbar spondylolysis in young athletes than previously thought, highlighting a lack of sport-specific studies on this condition.
- The study aimed to identify risk factors associated with upper lumbar stress injuries in pediatric and adolescent athletes by reviewing medical records from two academic centers.
- Results showed that the majority of diagnosed athletes had lower level injuries, while a smaller percentage experienced upper level injuries, which were linked to being older at diagnosis and shorter durations of low back pain.
Successful Conservative Treatment of Cervical Spondylolysis in a 2-year-old Patient.
J Orthop Case Rep

Musculoskeletal Oncology Pathology Unit, Traumatology and Orthopedics Clinic of UdelaR at the National Institute of Orthopedics and Traumatology, Montevideo, Uruguay.
Introduction: Cervical spondylosis is a rare condition in pediatric patients with currently scarce cases in the literature. The C2 location is particularly uncommon with only a small number of case reports describing this condition. Given its limited evidence in the literature, its etiology and standard of care treatment persist obscure.

- About one-third of cervical spine injuries happen in the upper section, specifically between the base of the skull (occiput) and the second cervical vertebra, with 70% of injuries occurring at this location.
- Types of injuries in this area include atlas fractures, occipital condyle fractures, and injuries to ligaments associated with the upper cervical spine.
- Treatment options range from conservative therapy for stable injuries to surgical intervention for unstable cases, with the article covering details on injury frequency, diagnosis, classification, and standard treatment methods.

Background Context: Prior studies have hypothesized that degenerative cervical spondylolisthesis (DCS) may be influenced by loss of stability due to disc, facet joint or cervical alignment. Meanwhile, it is commonly believed that the facet joints and paraspinal muscles participate in maintaining cervical spine stability. However, the impact of paraspinal muscle morphology and detailed facet joint features on DCS requires further investigation.
