Intended Use

The RHS is intended for: 1) Replacement of the radial head for degenerative or post-traumatic disabilities presenting pain, crepitation and decreased motion at the radio-humeral and/or proximal radio-ulnar joint with: a. Joint destruction and/or subluxation visible on x-ray b. Resistance to conservative treatment 2) Primary replacement after fracture of the radial head 3) Symptomatic sequelae after radial head resection 4) Revision following failed radial head arthroplasty The long stem is for single cemented use only. The short stem coated with titanium plasma-spray is for single use with or without cement.

Device Story

RHS is a radial head prosthesis designed to restore elbow joint function and relieve pain. Device consists of a metal radial stem and a metal-polyethylene radial head. Implanted by surgeons to replace damaged radial head tissue. Long stem requires cement; short stem (titanium plasma-spray coated) used with or without cement. Anatomical design mimics radial joint kinematics. Benefits include improved joint motion and pain reduction for patients with degenerative or post-traumatic conditions.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Radial head prosthesis consisting of a chromium-cobalt (CoCr) alloy stem and a CoCr shell with ultra-high molecular weight polyethylene (UHMWPE) head. Some stems feature titanium plasma-spray coating. Designed for cemented or cementless fixation depending on stem type. Class II device.

Indications for Use

Indicated for patients requiring radial head replacement due to degenerative or post-traumatic disabilities (pain, crepitation, decreased motion), joint destruction/subluxation, primary radial head fractures, symptomatic sequelae post-resection, or failed prior arthroplasty.

Regulatory Classification

Identification

An elbow joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace an elbow 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 consist of a humeral resurfacing component made of alloys, such as cobalt-chromium-molybdenum, and a radial resurfacing component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).

#### 6) Device description

The RHS has been designed in order to provide surgeons and patients with a joint prosthesis to restore function and relieve pain of the radial part of the elbow joint. The RHS has an anatomical design, which reproduces the kinematics of the radial joint. The RHS consists of two components: a metal radial stern and a metal-polyethylene radial head.

#### 7) Materials

The radial head is made of ultra high molecular weight polyethylene (UHMWPE), with a chromium-cobalt alloy (CoCr) shell. The stem is made of chromium-cobalt alloy. Some stems are plasma-spray coated with titanium.

### 8) Indications

The RHS is intended for:

- 1) Replacement of the radial head for degenerative or post-traumatic disabilities presenting pain, crepitation and decreased motion at the radio-humeral and/or proximal radio-ulnsor joint with:
- a. Joint destruction and/or subluxation visible on x-ray
- Resistance to conservative treatment b.
- 2) Primary replacement after fracture of the radial head
- 3) Symptomatic sequelae after radial head resection
- 4) Revision following failed radial head arthroplasty

The long stem is for single cemented use only. The short stem coated with titanium plasma-spray is for single use with or without cement.

The 'T' is bold and has a unique design, with a smaller hexagon shape incorporated within its structure. The logo is simple, using only black lines on a white background, giving it a clean and modern appearance.
