简要总结

Prestige artificial disc replacement is an alternative treatment option with 16 years of experience addressing the unmet needs of surgical fusion interventions. Previous studies on the PRESTIGE® cervical disc have proven the safety and effectiveness of artificial disc surgery with level I evidence.

The PRESTIGE Observational Study is intended to collect prospectively observational data primarily on the Quality of Life (QoL).

详细描述

Degenerative cervical disc disease is associated with a very high burden to the patient and the society. If conservative treatment options fail, surgical interventions are the last treatment option.

Symptomatic disc degeneration leads to neck pain, which can radiate to the scapula and arm, with dumbness and tingling, and sometimes grasping and walking difficulties. At an advanced stage, muscle weakness can be observed in the nerve territory.

The quality of life and functionality of patients with therapy-resistant (conservatively treated) severe degeneration of the disc is greatly impaired, as they suffer from intense pain and thus disability. Patients of working age were significantly more impacted by their symptoms than older patients. They are no longer able to fully participate in everyday activities.

Cervical neck pain resulting from degenerative disc disease is associated with a major economic burden for payers.

Traditional cervical surgical decompressions and fusions are currently the most common treatment option. Despite good treatment success rates, fusions are associated with a negative impact on the normal kinematics of the spine, long recuperation times and long absence from work. Prestige artificial disc replacement is an alternative treatment option.

结局指标

主要结局

Neck Disability Index (NDI) Score

时间窗: 2 years

The primary objective is the documentation of QoL before and after cervical disc surgery using the PRESTIGE® Cervical Disc System. The QoL will be determined using the EQ-5D questionnaire and the Neck Disability Index (NDI). The NDI is a self-reported questionnaire designed to provide information on how neck pain affects the patient's ability to manage in everyday life. It contains questions on 10 items including pain, personal care, lifting, reading, headaches, concentration, work, driving, sleeping and recreation. NDI results can be presented as a raw score or as a percent. When presenting it as a raw score, each section is scored on a 0 to 5 rating scale and the result is summarized to a total score with a maximum score of 50. This raw score can also be doubled and expressed as a percentage. Zero points or 0% means no activity limitations and 50 points or 100% means complete activity limitation.

EQ-5D

时间窗: 2 years

The primary objective is the documentation of QoL before and after cervical disc surgery using the PRESTIGE® Cervical Disc System. The QoL will be determined using the EQ-5D questionnaire and the Neck Disability Index (NDI). EQ-5D is an instrument for measuring health outcome and consists of five dimensions: mobility, selfcare, usual activities, pain/discomfort, and anxiety/depression and a Visual Analog Scale that can be used as a quantitative measure of health as judged by the patient. Each dimension has 3 levels (no problems = 1, some problems = 2, and extreme problems = 3). The EQ-5D index has an upper limit of 1 that indicates full health (indicated by "no problem" in all domains), whereas 0 represents death. Scores worst than 0 are possible, implying that some health states may be worse than death.
