Read the full statement (206 words)
The Equinoxe Humeral Reconstruction Prosthesis System is intended for use in hemi or total shoulder arthroplasty where proximal humeral resection is deemed necessary in cases of:
• Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis
• Rheumatoid arthritis
• Revision where other devices or treatments have failed
• Correction of functional deformity
• Treatment of acute or chronic fracture with humeral head involvement, which are unmanageable using other treatment
• Traumatic arthritis
• Oncology applications including bone loss due to tumor resection.
• Significant humeral resection which are unmanageable using other treatment methods
The Equinoxe Humeral Reconstruction Prosthesis System can be used in either primary or revision arthroplasty procedures.
The Equinoxe Humeral Reconstruction Prosthesis System is indicated for proximal humeral replacement in conjunction with reverse shoulder arthroplasty in which significant resection of the proximal humerus is necessary, the rotator cuff is irreplaceable and grossly deficient, and a functional deltoid muscle is present.
In the USA, the Equinoxe Humeral Reconstruction Prosthesis System is not indicated for use with the Equinoxe Reverse Shoulder System components in oncology applications.
The Equinoxe Humeral Reconstruction Prosthesis Distal Stems are for cemented use only, while the HA coated Equinoxe Humeral Reconstruction Prosthesis Distal Stem Collars are only for uncemented, press-fit use.
Indications for use as stated in the FDA summary.
