Total Cervical Immobilization. Rigid SOMI Design.
The Prim E45 I.M.O. SOMI Collar is a high-level cervical-thoracic orthosis designed for complete immobilization of the cervical spine. Standing for Sternal Occipital Mandibular Immobilizer, this collar utilizes a rigid thoracic plate that rests on the chest like a vest, connected to adjustable chin and occipital supports. This advanced system is specifically engineered to prevent flexion, extension, and rotation of the neck, making it the clinical gold standard for severe trauma and postoperative recovery. Despite its rigid protection, the back-less design allows patients to lie down comfortably without compromising the alignment of the spine.

Frequently Asked Questions
Can I eat while wearing the SOMI collar?
Yes. One of the unique benefits of the Prim E45 is that the mandibular (chin) support can be temporarily removed and replaced with a frontal head support. This frees the jaw for eating and talking while maintaining full cervical immobilization.
Is this collar comfortable for sleeping?
Unlike standard rigid collars that have bulky plastic at the back of the neck, the SOMI collar uses thin metal bars behind the head. This allows the patient to lie flat on a pillow comfortably while the device continues to provide 100% stabilization.
How is this better than a standard rigid collar?
A standard collar relies on the neck's soft tissue for support. The SOMI collar anchors to the sternum (chest), providing a much more rigid and stable base that prevents even the smallest micro-movements, which is essential for healing cervical fractures.
