## Indications for use
The Humelock II Reversible Shoulder is indicated for primary, fracture or revision total shoulder arthroplasty for the relief of pain and to improve function in patients with a massive and non-repairable rotator cuff tear. The patient’s joint must be anatomically and structurally suited to receive the selected implants and a functional deltoid muscle is necessary to use the device. The humeral stems are intended for cemented or cementless use. The metaglene baseplate is intended for cementless use with the addition of screws for fixation. The Humelock Reversed Shoulder is indicated for primary, fracture or revision total shoulder arthroplasty for the relief of pain and to improve function in patients with a massive and non-repairable cuff tear. The patient’s joint must be anatomically and structurally suited to receive the selected implants and a functional deltoid muscle is necessary to use the device. During primary or revision surgery, if the glenoid bone stock appears to be insufficient to bear the reversed glenoid components or the glenoid bone fractures during the procedure, a taper adapter can be used to convert the Humelock Reversed Shoulder to an anatomic hemi-shoulder prosthesis. The humeral stem of the Humelock Reversed Cemented Shoulder Prothesis is intended for cemented use only. The humeral stem of the Humelock Reversed Cementless Shoulder Prothesis is lockable with two cortical bone screws and is intended for cementless use only. An optional anti-rotational spoiler can be used with either the cementless or the cemented stems. The glenoid baseplate and post extension are intended for cementless use with the addition of screws for fixation. In an anatomic shoulder configuration, the Humeris Shoulder System is indicated for use in total and hemi-shoulder replacement to treat: - A severely painful and/or disabled joint resulting from osteoarthritis or rheumatoid arthritis; - Other difficult clinical problems where shoulder arthrodesis or resection arthroplasty are not acceptable (e.g. revision of a previously implanted primary component, a humeral plate or a humeral nail). In a reverse shoulder configuration, the Humeris Shoulder is indicated for primary or revision total shoulder arthroplasty for the relief of pain and to improve function in patients with a massive and non-repairable rotator cuff tear. The patient’s joint must be anatomically and structurally suited to receive the selected implants and a functional deltoid muscle is necessary to use the device. The humeral stem of the Humeris Cementless Shoulder is intended for cementless use only. The humeral stem of the Humeris Cemented Shoulder is intended for cemented use only. The glenoid components of the Humeris Shoulder System are intended for cemented use only. The glenoid baseplate component is intended for cementless use with the addition of screws for fixation.
