Intended Use

The Reverse Humeral Socket Shell is indicated for revision surgeries in patients with a grossly rotator cuff deficient shoulder joint with severe arthropathy or a previously failed joint replacement with a grossly rotator cuff deficient shoulder joint. The patient's joint must be anatomically and structurally suited to receive the selected implant(s), and a functional deltoid muscle is necessary to use the device. The socket shell is only indicated for use with a well fixed Turon Humeral Stem.

Device Story

Reverse Humeral Socket Shell; orthopedic implant used in revision shoulder arthroplasty. Device mates with existing well-fixed Turon Humeral Stem to convert system to reverse shoulder configuration. Used by orthopedic surgeons in clinical/hospital settings. Provides structural support for reverse shoulder joint replacement in patients with rotator cuff deficiency. Benefits include enabling revision of failed shoulder replacements or severe arthropathy without requiring full stem removal. Operates as mechanical prosthesis; no electronic or software components.

Clinical Evidence

No clinical data provided. Equivalence established via non-clinical bench testing, including fatigue testing of the socket shell/stem assembly and mechanical strength testing (torsional, lever-out, push-out, pull-out) based on predicate geometry.

Technological Characteristics

Metal/polymer semi-constrained cemented shoulder prosthesis. Features morse taper connection for mating with Turon Humeral Stem. Mechanical design utilizes same locking feature geometry as predicate RSP socket shells. Fatigue testing performed per ASTM standards.

Indications for Use

Indicated for revision surgeries in patients with grossly rotator cuff deficient shoulder joint with severe arthropathy or failed joint replacement. Requires anatomically/structurally suited joint and functional deltoid muscle. Contraindicated if joint not suited or deltoid non-functional.

Regulatory Classification

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).

Dear Ms. Hutto:

This letter corrects our substantially equivalent letter of September 16, 2011.

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

KWS Shoulder joint metal/polymer semi-constrained prosthesis per 21 CFR 888.3660

Description: In cases of revision surgeries to a well fixed Turon Humeral socket shell ! can be mated with the Turon stem to convert to a reverse shoulder application.

There is no change to the intended use or fundamental scientific technology. This includes no changes to currently cleared devices, packaging or sterilization.

### Indications for Use:

The Turon to RSP Conversion Shell is indicated for revision surgeries in patients with a grossly rotator cuff deficient shoulder joint with severe arthropathy or a previously failed joint replacement with a grossly rotator cuff deficient shoulder joint. The patient's joint must be anatomically and structurally suited to receive the selected implant(s), and a functional deltoid muscle is necessary to use the device. The socket shell is only indicated for use with a well fixed Turon Humeral Stem.

# Predicate Device:

- DJO Surgical Reverse® Shoulder Prosthesis K041066 ●
- Turon Shoulder System K080402 ●

Comparable Features to Predicate Device(s): Features comparable to predicate devices include the same design features, indications, sterilization, and intended use.

# Non-Clinical Testing:

- Fatigue Testing was performed on the socket shell assembled with the Turon stem to demonstrate that . the component would withstand minimum load conditions per ASTM standards. The results of the testing determined that the socket shell could withstand the load conditions showing equivalence to the cleared Turon socket and stem interface.
- Because the locking feature geometry of the Reverse Humeral Socket Shell is the same as the . predicate RSP socket shells, Torsional Strength, Lever out Strength, and Push Out Strength performed against the RSP socket shell can be applied to the Reverse Humeral Socket Shell.
- Because the mating geometry of the morse taper connection is the same as the predicate Turon ● Humeral Neck, Pull-out Testing conducted with the cleared Turon stem can be applied.

The above testing demonstrated the device's ability to perform under expected conditions and is equivalent to the predicate devices.

Clinical Testing: None provided.
