The Identity™ Shoulder System gives surgeons the ability to adapt to patient needs - both present and future - with confidence.
Identity offers an innovative solution to personalize humeral head inclination, version and offset in-situ. Proprietary technologies expand on traditional inlay/onlay philosophies, enabling surgeons to alter humeral lateralization / medialization independently of arm lengthening.
Adaptability for the Patient
Proprietary technologies give surgeons the power to "dial in" to patient's natural anatomy, along with ability for surgeon to convert from TSA to RSA in-situ.
Adaptability for the Surgeon
Surgeons can align the patient’s anatomical needs to surgical techniques, converting from TSA to RSA in-situ if needed.
In RSA procedures, Identity expands on traditional inlay and onlay philosophies with humeral trays that empower surgeons to locate the optimal dwell point for the implant, allowing for medialization and distalization without lengthening the arm.
Adaptability for the Future
The system design allows for stem preservation and TSA with an extra 5mm of joint space* in the patient, facilitating future revision if needed
Anatomic adaptability with Versa-Dial® technology to promote soft tissue balancing, a broad implant scope for sizing and dedicated instruments for in-situ conversion.
Reverse adaptability with onlay and inset humeral trays in one system, plus standard and extended humeral trays for more sizing and placement options
Anatomic stability with Versa-Dial® Technology, featuring a minimized gap stem and head design that allows the humeral head to be rotated eccentrically for optimal coverage and soft tissue tensioning.
Reverse stability with humeral trays and bearings in extended sizes that enable surgeons to decouple medialization and/or lateralization from arm lengthening. This facilitates soft tissue tensioning by allowing for titrate deltoid tensioning in a single direction with respect to the acromion.
Convert from anatomic to reverse without disturbing a well-fixed stem.
The Identity stem sits below the resection, enabling a bearing construct designed to help save time, preserve bone, and minimize trauma to the patient that would otherwise be required with stem removal systems.
Identity Humeral Trays expand on traditional inlay/ onlay concepts to help surgeons optimize deltoid tensioning during reverse. Trays feature Vivacit-E® Vitamin E Highly Crosslinked Polyethylene in humeral head bearings for exceptional wear resistance9, long-term oxidative stability10,11, and improved strength12 as compared to conventional polyethylene**.
Alliance® Glenoid allow seamless transition between standard and augmented glenoids when addressing posterior erosion, and features a Trabecular Metal® center post to foster biologic in-growth fixation1-8 inside the glenoid vault.
Versa-Dial® Humeral Heads allows surgeon to tailor humeral head offset for each patient to help optimize soft tissue balancing.
