## Indications for use
SYSTEM INTENDED USE: The Aequalis Ascend Flex Shoulder System is intended for use as: • A replacement of shoulder joints in primary anatomic or in primary reverse. • A replacement of other shoulder joints devices in case of revisions if sufficient bone stock remains. • The Aequalis Ascend Flex Shoulder System also allows for conversions from anatomic to reverse shoulder prosthesis in case of revision. IN ANATOMIC: The stem and head may be used by themselves, as a hemiarthroplasty, if the natural glenoid provides a sufficient bearing surface, or in conjunction with the glenoid, as a total replacement. The Aequalis Ascend Flex Shoulder System is to be used only in patients with an intact or reconstructable rotator cuff, where it is intended to provide increased mobility and stability and to relieve pain. The Aequalis Ascend Flex Shoulder System is indicated for use as a replacement of shoulder joints disabled by: * Rheumatoid arthritis with pain * Non-inflammatory degenerative joint disease (i.e. osteoarthritis and avascular necrosis) * Correction of functional deformity * Fractures of the humeral head * Traumatic arthritis • Revision of other devices if sufficient bone stock remains IN REVERSE: The Aequalis Ascend Flex Shoulder System is indicated for use as a replacement of shoulder joints for patients with a functional deltoid muscle and with massive and non-repairable rotator cuff-tear with pain disabled by: Rheumatoid arthritis; Non-inflammatory degenerative joint disease (i.e. osteoarthritis and avascular necrosis); Correction of functional deformity; Fractures of the humeral head; Traumatic arthritis; Revision of the devices if sufficient bone stock remains. The reversed adapter is indicated for use as components of the Aequalis Ascend Flex Shoulder System total shoulder replacement and for transformation of the Aequalis Ascend Flex Shoulder System into a reverse shoulder prosthesis without the removal of the humeral stem during revision surgery for patients with a functional deltoid muscle. The components are permitted to be used in the transformation from anatomic to reverse if the humeral stem is well fixed, the patient has a functional deltoid muscle; the arthropathy is associated with a massive and non-repairable rotator cuff-tear. Notes: All components are single use; The coated humeral stem is intended for cemented or cementless use; The non-coated humeral stem is intended for cemented use only; All poly glenoid components are intended for cemented use only; The glenoid sphere implant is anchored to the bone with screws and is for non-cemented fixation.; Titanium humeral heads are intended for patients with suspected cobalt alloy material sensitivity. The wear properties of Titanium and Titanium alloys are inferior to that of cobalt alloy. A titanium humeral head is not recommended for patients who lack a suspected material sensitivity to cobalt alloy.
