The Shoulder Innovations Total Shoulder System with Humeral Stemless is intended for use as an orthopedic implant for total shoulder arthroplasty to treat severely painful and/or disabled joint resulting from osteoarthritis or traumatic arthritis.
The Shoulder Innovations Total Shoulder System components are intended for single use only.
The Humeral Stemless components are indicated for press-fit, un-cemented use. The glenoid component is intended for cemented fixation only.
The Shoulder Innovations Total Shoulder System consists of modular humeral stems and heads that articulate with a glenoid component. The humeral stems are collarless, as the humeral head acts as the collar, and manufactured from Titanium Alloy (Ti-GAL-4V) conforming to ASTM F136 with fins to provide rotational stability and are coated with a rough, porous coating. The stems have a female Morse-type taper to interface with the modular humeral heads. The humeral heads are manufactured from CoCr and are available in standard and offset configurations. The heads have a male Morse-type taper to interface with the humeral stems.
The glenoid components of the Total Shoulder System are manufactured from Ultra High Molecular Weight Polyethylene (UHMWPE) with a pegged design intended for cemented fixation.
This submission adds Humeral Stemless Implants to the Shoulder Innovations Total Shoulder System. The Humeral Stemless Implants are similar to the previously cleared humeral short stems (K173824), except that the Humeral Stemless Implants do not include the stem. The Humeral Stemless Implants have fins to provide rotational stability and a female Morse-type taper to interface with modular humeral heads, identical to the humeral short stems (K173824). The Humeral Stemless Implants are manufactured from Titanium Alloy (Ti-6Al-4V) conforming to ASTM F136 with a proximal porous coating of commercially pure titanium according to ASTM F67.
The Humeral Stemless Implants are for press-fit, uncemented use. All Humeral Stemless Implants are compatible with the previously cleared Total Shoulder System humeral heads (K173824) and previously cleared Total Shoulder System glenoid components (K111596 and K192365).
The provided text is a 510(k) premarket notification for a medical device (Shoulder Innovations Total Shoulder System with Humeral Stemless). It outlines the device description, indications for use, and a summary of non-clinical testing and substantial equivalence to predicate and reference devices.
Crucially, it clearly states that "Clinical testing was not necessary to demonstrate substantial equivalence" for this device. This implies that the device's acceptance was based on non-clinical testing and a comparison to already cleared devices, rather than a clinical study evaluating its performance against specific clinical acceptance criteria.
Therefore, I cannot fulfill your request to describe acceptance criteria and a study proving the device meets those criteria, as the document explicitly states no clinical study was performed for this specific submission to demonstrate substantial equivalence.
The provided text does not contain the information requested regarding acceptance criteria related to a clinical study proving device performance. There is no information about:
- A table of acceptance criteria and reported device performance: No clinical performance metrics or predefined acceptance thresholds are mentioned.
- Sample size used for the test set and data provenance: No clinical test set.
- Number of experts used to establish ground truth and their qualifications: Not applicable, as no clinical ground truth was established from expert readings.
- Adjudication method: Not applicable.
- Multi Reader Multi Case (MRMC) comparative effectiveness study: No such study was conducted.
- Standalone (algorithm only) performance: Not applicable, as this is a physical medical device, not an AI algorithm.
- Type of ground truth used: No clinical ground truth was used.
- Sample size for the training set: Not applicable, as this is not an AI/ML device requiring a training set.
- How ground truth for the training set was established: Not applicable.
The document focuses on non-clinical testing (lever out, pull out, torque out, and fatigue testing) to demonstrate substantial equivalence based on mechanical properties and design similarity to predicate devices, rather than clinical efficacy or diagnostic performance.
§ 888.3660 Shoulder joint metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A shoulder joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a shoulder joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a humeral resurfacing component made of alloys, such as cobalt-chromium-molybdenum, and a glenoid resurfacing component made of ultra-high molecular weight polyethylene, and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
