Abstract
Background Arthroplasty has been proven to be a safe and effective treatment for patients with cervical degenerative disk disease (DDD). Dynamic Cervical Implant (DCI) has emerged as a novel implantation device for cervical DDD. This study aimed to compare the outcomes of these procedures after 5 years of follow-up in the DCI and arthroplasty groups.
Methods This study retrospectively enrolled 79 consecutive cervical DDD patients with 41 DCI and 47 prostheses implanted. Radiographs were analyzed for intervertebral height and range of motion (ROM). Neural function of the patients was assessed using the Neck Disability Index score, visual analog scale, Japanese Orthopaedic Association score and 36-Item Short Form Survey.
Results The DCI group had statistically lesser flexion/extension and bilateral bending ROM than the arthroplasty group at the operated level(s) (p < 0.05). The DCI group but not the orthoplast group showed improved lordotic alignment of C2–C7 and operated functional spinal unit (p < 0.05). No statistical difference was observed in the neural function of the two groups. Heterotopic ossification was found in 7 and 14 patients in the DCI and arthroplasty groups, respectively.
Conclusion The 5-year follow-up results were comparable between the two groups. We believe that DCI implantation is a safe and effective procedure and could possibly become an alternative treatment for cervical DDD.

BACKGROUND: Patient compliance is essential to the effectiveness of brace treatment for adolescent idiopathic scoliosis (AIS) patients. Subjective measurements like questionnaires and inquiries proved to be arguably inaccurate. Although some scholars have applied temperature/force monitors to measuring patient compliance objectively, few studies to date could monitor patient compliance in real time. The objective of this study is to describe and evaluate a compliance real-time monitoring system of the brace usage in AIS patients. METHODS: A compliance real-time monitoring system (specifically consisting of a compliance monitor, a WeChat Mini Program, a cloud-based storage system and a website backstage management system) was designed to manage the brace treatment. Thirty patients receiving brace treatment were enrolled. They were told to upload the data at least once a day. Clinicians downloaded the compliance data and communicated with the patients online based on their analysis of data at least once every 3 months. The measured force, quality compliance (measured force / baseline force), measured time, and quantity compliance (measured time/ prescribed time) were used to evaluate patient compliance. Patients were also asked to rate their satisfaction at the final follow-up. RESULTS: Twenty-eight patients were included in the final analysis. The mean baseline force was 1.23 ± 0.28 N. The mean measured force was 0.79 ± 0.29 N. The mean quality compliance was 64.8 ± 22.2%. The prescribed time of all patients was 23 h. The mean measured time was 14.1 ± 2.9 h. The mean quantity compliance was 61.3 ± 12.6%. Both the quality and quantity compliance during the first 3 months of treatment was significantly lower than the latter 3 months. In this study, 96.4% (27/28) patients were satisfied with the use of the monitoring system, among whom 21.4% (6/28) are very satisfied and 75.0% (21/28) are somewhat satisfied. CONCLUSIONS: The compliance real-time monitoring system, without evaluating the clinical and radiographic ...
