The Aequalis Glenoid Guides are patient-specific drill guides. They have been specially designed to assist in the intraoperative positioning of glenoid components used with total anatomic shoulder arthroplasty procedures using anatomic landmarks that are identifiable on patient-specific preoperative CT-scans. Aequalis PerFORM Anatomic Glenoid Guide is used by surgeons to facilitate the placement of the Aequalis PerFORM glenoids. The software The BLUEPRINT 3D planning software is a medical device for surgeon composed of one software component. It is intended to be used as a pre-surgical planner for shoulder orthopedic surgery. BLUEPRINT 3D planning software runs on standard personal and business computers running Microsoft Windows or Mac OS operating systems. The software supports DICOM standard to import the CT-Scan (Computed Tomography) images of the patient. Only CT-Scan modality can be loaded with BLUEPRINT3D planning software. BLUEPRINT 3D planning software allows surgeon to visualize, measure, reconstruct, and annotate anatomic data. It allows surgeon to design patient specific guides based on the presurgical plan. This device is intended for use provided anatomic reference points necessary for positioning of the guide are present on the CT scan. The software leads to the generation of a surgery report along with a 3D file of the patient-specific guide. BLUEPRINT 3D planning software does not include any system to manufacture the guide. BLUEPRINT 3D planning software is to be used for adult patients only and should not be used for Diagnostic purpose.

BLUEPRINT™ Patient Specific Instrumentation is composed of two components: Aequalis Glenoid Guides (hardware) and BLUEPRINT 3D planning software (software). BLUEPRINT™ Patient Specific Instrumentation is the responsibility of Tornier including the Aequalis Glenoid Guides and BLUEPRINT 3D planning software. Tornier is the legal manufacturer for the hardware and the software. The hardware The Aequalis Glenoid Guides are patient-specific instruments specially designed to facilitate the implantation of the Aequalis PerFORM shoulder prostheses and are exclusively reserved for this use. The Aequalis Glenoid Guides are designed and manufactured based on a pre-operative plan generated only by the software BLUEPRINT™ 3D planning software. The software BluePrint 3D Planning software is composed of one software component connected to an Online Management System (OMS). The software installed on a computer is intended to be used by orthopedic surgeons, as a preoperative planning software for shoulder arthroplasty surgery (= total anatomic shoulder replacement). It is intended to help to plan an operation by allowing surgeons to: - position and to select the glenoid implant, ● - design a patient specific pin guide.

Cemented Aequalis Reversed prosthesis: It is indicated for patients with a functional deltoid muscle as a total shoulder replacement for the relief of pain and significant disability following arthropathy associated with the massive and non repairable rotator cuff-tear. This device is also indicated for the prosthetic revisions with massive and non repairable rotator cuff-tear. Only the humeral components are for cemented use. The glenoid implant is anchored to the bone with 4 screws and is for non-cemented fixation. When during the primary surgery the glenoid bone stock appears to be insufficient to bear the reversed glenoid components or when glenoid bone fracture occurs during the surgical procedures, the hemi-prosthesis adaptor and the union screw can be adapted to the humeral components in order to transform the Aequalis Reversed prosthesis into a non reversed hemi-prosthesis. When, in case of revision of a Aequalis Reversed prosthesis, the glenoid bone stock appears to be insufficient to again implant a base plate and a sphere of Aequalis Reversed range, the use of the hemi-prosthesis adaptor and the union screw allows for the transformation of the Aequalis Reversed prosthesis in to a non reversed hemi-prosthesis in order to avoid the revision of the humeral components. Uncemented Aequalis Reversed prosthesis: It is indicated for patients with a functional deltoid muscle as a total shoulder replacement for the relief of pain and significant disability following arthropathy associated to massive and non repairable rotator cuff-tear.

The Aegualis Reversed Shoulder Prosthesis is intended to relieve pain and significant disability following massive and non repairable cuff-tear associated to arthropathy and following massive cuff-tear arthropathy. In this case, the rotator muscles of the shoulder (supraspinatus, teres minor and long head of the biceps) are no more useful for mobility, and only the deltoid (for abduction and external rotation) and the subscapularis (for internal rotation) are functional. Therefore, the usual goal of such surgery is to restore the shoulder joint to facilitate its working condition and to relieve pain. The reversed design allows to medialize the center of rotation of the shoulder, lengthening the deltoid muscle lever arm. The Aequalis Reversed Shoulder Prosthesis is a semi-constrained system composed of a humeral and a glenoid parts. The present device modification consists in the addition of glenoid base plates with central threaded post and a new coating.
