Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study's main purpose is the collection of clinical data on the patients benefit and safety of pedicle screw placement through an innovative minimally invasive surgical approach compared to the state of the art open surgical approach using the Ennovate® Cervical Spinal System.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Subjects will be randomly allocated to one of the two study groups in a 1:1 ratio.

In addition, stratification by clinical investigation sites is applied. Group 1: Patients treated with the Ennovate® Cervical system using an open surgical technique. Group 2: Patients treated with the Ennovate® Cervical system using a minimally invasive technique. Study is designed to provide a comparison of the both groups regarding the short-term pain outcome.
Primary Study Purpose

TREATMENT

Blinding Strategy

SINGLE

Participants
Block randomization with random block length will be used. The electronic data capture system will instruct the clinical investigator to use either the open or the minimally invasive surgical technique.

Study Groups

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* All patients with minimum 18 years of age receiving Ennovate® Cervical internal fixation device within the vertebral bodies C2-Th3 to ensure the restoration and stabilization of the cervical spine

Exclusion Criteria

* All patients not willing to sign the patient consent are excluded. Also, if it is clear from the beginning, that the patient will not be able to come to routine follow-up, the patient will also be excluded.

Absolute contraindications according to the IFU:

* Severe damage to the bone structures of the spine that could prevent the stable implantation of the implant components; for example, osteopenia, severe osteoporosis, Paget's disease, bone tumors etc.
* Metabolic or degenerative metabolic bone diseases that could compromise the stable anchoring of the implant system.
* Suspected allergy or sensitivity to the implant materials.
* Acute or chronic vertebral infections of a local or systemic nature.
* Poor patient compliance or limited ability to follow medical instructions, particularly in the postop phase, including with regard to the restrictions on range of movement in terms of physical exercise and occupational activity.
