Post-Market Clinical Follow-Up Study on the Safety and Performance of Ennovate® Complex

Recruiting

• Conditions: Neuromuscular Scoliosis; Hyperlordosis; Hyperkyphosis; Congenital Scoliosis; Idiopathic Scoliosis
• Interventions: Device: posterior stabilization for the cervical spine

• Registration Number: NCT05281757
• Lead Sponsor: Aesculap AG

Brief Summary

Multicenter, multinational Post-Market Clinical Follow-Up (PMCF) study on the safety and performance of Ennovate® Complex - A prospective, pure data collection of all Ennovate® scoliosis patients in selected centers (not interventional, multicentric)

Detailed Description

This clinical study is one of the Post-Market Clinical Follow-Up (PMCF) measures that enables the manufacturer to monitor the clinical safety and performance of the Ennovate® Complex system.

The study enables a quick, but detailed implant documentation, which is of great interest for the current and future users of the internal fixation system targeted in this study. It includes the relevant outcomes to evaluate safety and efficacy of the implant system for various indications in deformity disorders.

Arm && Interventions

Group	Intervention	Description
Ennovate® Complex	posterior stabilization for the cervical spine	All patients who are treated with the Ennovate® Complex system in accordance with indications given in the instructions for use (IFU)

Primary Outcome Measures

Name	Time	Method
Change of Pain	preoperatively, at 3-4 months postoperatively and at approximately 12 and 24 months postoperatively	ain will be assessed by the patient using the Visual Analogue Scale (VAS) which state "0" at one end representing "no pain" and "100" at the opposite end representing "maximal / worst pain".

Secondary Outcome Measures

Name	Time	Method
Change of Quality of Life	preoperatively, at 3-4 months postoperatively and at approximately 12 and 24 months postoperatively	In order to analyze the quality of life of the patients, the most current questionnaire of the Scoliosis Research Society (SRS), the "SRS-30" is used. The SRS-30 demonstrates how spinal conditions impact quality of life and facilitate comparisons of the quality of life before and after surgical intervention. It is widely used in the evaluation of the treatment of idiopathic scoliosis patients. SRS-30 is a patient self administered questionnaire and has a minimum score of 30 and a maximum score of 150 including postsurgery questions. Each question is scored on 1-5 scale. Questions are sorted into different domains and total and mean scores for each domain are calculated. A total score for the entire questionnaire is also calculated.
Bone Fusion	at final follow-up approximately 24 months after surgery	After Complex stabilization fusion of the treated segment is aspired in most cases. The fusion status can be determined from radiographs (static or dynamic). Bony fusion can be characterized quantitatively by the fusion rate.
Cumulative number of Side effects	throughout the follow-up up to 24 months postoperatively	Occurrence of complications potentially associated with the implanted devices can never be fully excluded during spinal surgery. In order to monitor potential complication and to identify so far unknown complications Adverse Events and Serious Adverse Events deemed related to the investigational device are recorded.
Change of Every day life	preoperatively, at 3-4 months postoperatively and at approximately 12 and 24 months postoperatively	Clinical Results measured by Oswestry Disability Index (ODI). ODI contains ten topics concerning intensity of pain, lifting, ability to care for oneself, ability to walk, ability to sit, sexual function, ability to stand, social life, sleep quality, and ability to travel, each topic category is followed by 6 statements describing different potential scenarios in the patient's life relating to the topic. Each question is scored on a scale of 0 (indicating the least amount of disability) to 5 5 (indicating most severe disability). The scores for all questions answered are summed, then multiplied by two to obtain the index (range 0 to 100). Zero is equated with no disability and 100 is the maximum disability possible.
