Intended Use

The Type 3 Femoral Components are intended to be used in primary or revision total hip arthroplasty, specifically in the presence of severe proximal bone loss. These stems are intended to be used with Howmedica V40™ femoral heads, Howmedica Unipolar and Bipolar components, and Howmedica acetabular components. These femoral stems are designed to be press fit into the proximal femur.

Device Story

Type 3 Femoral Components are modular titanium alloy femoral stems designed for primary or revision total hip arthroplasty in cases of severe proximal bone loss. Stems are press-fit into the proximal femur. Device is used in clinical/surgical settings by orthopedic surgeons. Components are modular, featuring varying proximal body and distal stem sizes to accommodate anatomical requirements. Stems are intended for use with Howmedica V40 femoral heads, Unipolar/Bipolar components, and acetabular components. The device provides structural support for the hip joint, aiming to restore function in patients with significant bone loss.

Clinical Evidence

Bench testing only. Fatigue load carrying capacity testing was performed and demonstrated that the device exceeds minimum ISO load requirements.

Technological Characteristics

Material: Titanium alloy (Ti-6Al-4V) conforming to ASTM F 136. Design: Modular femoral stems with varying proximal body and distal stem sizes. Fixation: Press-fit. Energy source: None (mechanical). Connectivity: None.

Indications for Use

Indicated for patients undergoing primary or revision total hip arthroplasty, specifically those with severe proximal bone loss.

Regulatory Classification

Identification

A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.

K983404

Proprietary Name: Type 3 Femoral Components

Common Name: Hip Prosthesis

21 CFR 888.3353 Classification Name and Reference:

Hip Joint Metal/Ceramic/Polymer semi-constrained cemented or nonporous uncemented prosthesis.

Proposed Regulatory Class: Class II

Device Product Code: LZO

For information contact: Frank Maas Manager, Regulatory Affairs Howmedica Inc. 359 Veterans Boulevard Rutherford, NJ 07070 Telephone: [phone] [phone] Fax: Date Summary Prepared: 9-25-98

The Type 3 Femoral Components are a series of Titanium femoral stems intended to be used for primary or revision total hip arthroplasty, specifically in the presence of severe proximal bone loss. The stems are intended to be used with Howmedica V40™ femoral heads, Howmedica Unipolar and Bipolar components, and Howmedica acetabular components. These stems are modular, with varying proximal body and distal stem sizes to accommodate various anatomical requirements. These femoral stems are designed to be press fit into the proximal femur.

These femoral components are manufactured from Titanium alloy, Ti-6Al-4V, which conforms to the requirements of ASTM specification F 136.

The substantial equivalence of these Femoral components is based on an equivalence in intended use, materials, design, and relative indications and contraindications to Howmedica's Partnership™ Revision Femoral Components (K972893) and Modular Replacement System (K954559), Intermedics Orthopedics' Wagner Revision Stem (K960588) and Link's MP Reconstruction Hip System.

Testing has demonstrated that the fatigue load carrying capacity of the Type 3 Femoral stems exceeds the minimum ISO load requirements.
