Intended Use
The Equinoxe Shoulder System is indicated for use in skeletally mature individuals with degenerative diseases or fractures of the glenohumeral joint where total or hemiarthroplasty is determined by the surgeon to be the preferred method of treatment. The cemented primary humeral stem, long/revision stem, fracture stems and all Equinoxe glenoids are intended for cemented fixation. The press-fit humeral stems are intended for press-fit applications but may be used with bone cement at the discretion the surgeon. The reverse humeral components are intended to be used in cemented applications or in revision cases when the humeral component is well-fixed/stable, as deemed by the orthopaedic surgeon. Humeral Heads are intended for use in cemented and press-fit applications. Clinical indications for the PRIMARY (P), LONG/REVISION (L/R) and FRACTURE (F) humeral components are as follows: rheumatoid arthritis, osteoarthritis, osteonecrosis or post-traumatic degenerative problems congenital abnormalities in the skeletally mature primary and secondary necrosis of the humeral head. humeral head fracture with displacement of the tuberosities pathologies where arthrodesis or resectional arthroplasty of the humeral head are not acceptable revisions of humeral prostheses when other treatments or devices have failed (where adequate fixation can be achieved) displaced three-part and four-part upper humeral fractures spiral and other fractures of the mid-humerus (in combination with glenohumeral degenerative diseases) revision of failed previous reconstructions when distal anchorage is required to restore mobility from previous procedures (e.g. previous fusion) The Equinoxe Reverse Shoulder System is indicated for use in skeletally mature individuals with degenerative diseases of the glenohumeral joint and a grossly deficient, irreparable rotator cuff. The Equinoxe Reverse Shoulder is also indicated for a failed glenohumeral joint replacement with loss of rotator cuff function resulting in superior migration of the humeral head. The Equinoxe Platform Fracture Stem is indicated for use in skeletally mature individuals with acute fracture of the proximal humerus and displacement of the tuberosities, displaced 3- and 4-part fractures of the proximal humerus (hemi-arthroplasty), or acute fracture of the proximal humerus with failure of the glenohumeral joint (primary total shoulder arthroplasty). The Equinoxe Platform Fracture Stem is also indicated for acute fracture of the proximal humerus in combination with degenerative diseases of the glenohumeral joint and a grossly deficient, irreparable rotator cuff resulting in superior migration of the humeral head (reverse total shoulder arthroplasty). The Equinoxe Platform Fracture Stem is indicated for cemented use only.
Device Description
The Equinoxe Shoulder System is comprised of primary, fracture and reverse product lines for use in hemi- and total-shoulder joint replacement procedures. The Equinoxe Primary and Fracture system utilize both cemented and press-fit, semi-constrained glenohumeral prostheses for use in hemi-shoulder and totalshoulder joint replacement procedures, and a cemented semi-constrained glenohumeral fracture prosthesis for use in fractures of the proximal humerus. The Equinoxe Reverse Shoulder System includes a reverse semi-constrained prosthesis for use in total-shoulder joint replacement procedures in cases with an irreparable or nonfunctional rotator cuff. The Equinoxe Reverse Shoulder System is designed to function with the Equinoxe primary press-fit, primary cemented, and long/revision humeral stems. The proposed fixed angle replicator plates are manufactured from wrought titanium alloy (Ti-6Al-4V E.L.I) per ASTM F136 and connect to the humeral stem via a spherical bowl and are locked in place using the previously cleared primary torque-defining screw. The replicator plate attaches to the humeral head using a morse taper. The mating features on the proposed replicator plates (specifically the morse taper geometry and the spherical bowl geometry) are identical to the predicate part, only the offset and angular adjustability have been altered. The proposed humeral heads are manufactured from Cast Cobalt-Chrome Alloy (Co-28Cr-6Mo) per ASTM F75 and provide an articulating surface for hemi and total joint replacement. They feature female taper geometry for mating with proposed and predicate replicator plate designs. No design changes have been made to this device. It is a material change only. The proposed glenospheres are manufactured from Cast Cobalt-Chrome Alloy (Co-28Cr-6Mo) per ASTM F75and connect to the plate via an apical hole screw and slip fit with oval shaped plate. No design changes have been made to this device. It is a material change only.
More Information

Not Found

No
The description focuses on the mechanical components and materials of a shoulder implant system. There is no mention of software, algorithms, or any technology that would suggest the use of AI or ML.

Yes
The device is a shoulder system used for joint replacement procedures due to degenerative diseases or fractures, which aligns with the definition of a therapeutic device as it is intended to treat a medical condition.

No

The device is a shoulder implant system (prosthesis) designed for joint replacement procedures, not for diagnosing medical conditions.

No

The device description clearly outlines physical components like humeral stems, glenoids, humeral heads, replicator plates, and glenospheres, which are manufactured from materials like titanium alloy and cobalt-chrome alloy. This indicates a hardware-based medical device, not a software-only one.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly describes a surgical implant for replacing or repairing the glenohumeral joint due to degenerative diseases or fractures. This is a therapeutic device, not a diagnostic one.
  • Device Description: The description details the components of a shoulder prosthesis (stems, heads, glenoids, plates, glenospheres) which are surgically implanted. This is consistent with a medical device for treatment, not for testing biological samples.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing diagnostic information about a patient's condition based on such analysis.

The device is a medical device intended for surgical implantation to treat musculoskeletal conditions.
