## Intended Use

EXPRT™ Revision Hip System is indicated for patients whose bone stock is of poor quality or inadequate for other reconstruction techniques as indicated by deficiencies of the femoral head, neck or portions of the proximal femur. It is intended for cementless revision hip arthroplasty on both uncemented and cemented femoral implants.

## Device Story

EXPRT™ Revision Hip System consists of non-porous distal femoral stem implants, proximal body implants, and capture bolts; all manufactured from titanium alloy (Ti6Al4V). Used by orthopedic surgeons in clinical settings for revision hip arthroplasty. System includes specialized instrumentation for bone preparation. Device provides structural support for patients with compromised femoral bone stock. Subject device expands compatibility to include all DJO Surgical femoral head configurations, unlike the predicate which was limited to -4 offset heads.

## Clinical Evidence

No clinical data. Substantial equivalence supported by non-clinical fatigue testing and endotoxin assessment.

## Technological Characteristics

Materials: Titanium alloy (Ti6Al4V) per ASTM F1472. Components: Non-porous distal femoral stem, proximal body implants, capture bolt. System is a modular hip prosthesis for revision arthroplasty.

## Regulatory Identification

A hip joint metal/polymer constrained cemented or uncemented prosthesis is a device intended to be implanted to replace a hip joint. The device prevents dislocation in more than one anatomic plane and has components that are linked together. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular component made of ultra-high-molecular-weight polyethylene with or without a metal shell, made of alloys, such as cobalt-chromium-molybdenum and titanium alloys. This generic type of device is intended for use with or without bone cement (§ 888.3027).

## Special Controls

*Classification.* Class II (special controls). The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance: Hip Joint Metal/Polymer Constrained Cemented or Uncemented Prosthesis.”

## Predicate Devices

## Description:

The EXPRT™ Revision Hip System includes non-porous distal femoral stem implants and nonporous proximal body implants, with bolt, all made from titanium alloy (Ti6Al4V) per ASTM F1472. System specific instrumentation allows the surgeon to prepare the bone to accept the EXPRT™ Revision Hip System implants.

## Indications for Use:

EXPRT™ Revision Hip System is indicated for patients whose bone stock is of poor quality or inadequate for other reconstruction techniques as indicated by deficiencies of the femoral head, neck or portions of the proximal femur. It is intended for cementless revision hip arthroplasty on both uncemented and cemented femoral implants.

EXPRT Revision Hip System – K161610 Predicate Devices:

Comparable Features to Predicate Device is comparable to the predicate devices in indications, material, design features, dimensions, surgical implantation technique, intended use, packaging, and sterilization.

{4}------------------------------------------------

Key Differences in Subject Device to Predicate: The key difference between the subject device and the predicate device is the use of compatible components. The predicate device only allowed use with -4 offset femoral heads. The subject device will allow all configurations of DJO Surgical femoral heads.

Non-Clinical Testing: Fatigue testing. All testing has determined that the device is substantially equivalent to the predicate devices.

Endotoxin Assessment: Bacterial endotoxin testing is equivalent to the previously cleared system.

Clinical Testing: Clinical testing was not required

Conclusion: All testing and evaluations demonstrate that the device is substantially equivalent to the predicates identified.
