Intended Use

The Excia Hip System is intended to replace a hip joint. The device is intended for: Patients suffering from severe hip and disability due to rheumatoid arthritis, traumatic arthritis, polyarthritis, collagen disorders, avascular necrosis of the femoral head and nonunion of previous fractures of the femur. Patients with congenital hip dysplasia, protrusion acetabuli, or slipped capital femoral epiphysis Patients suffering from disability due previous fusion Patients with acute femoral neck fractures The Excia Hip System is available with two femoral stems. One is manufactured from CoCrMo and is intended for cemented fixation. The other femoral stem is for uncemented fixation and manufactured from Ti with Plasmapore with or without u-CaP®.

Device Story

BIOLOX® delta Ceramic Femoral Head; alumina matrix composite ceramic component for total hip arthroplasty. Used as modular head option for Excia and Metha Hip Systems. Available in 28, 32, 36 mm diameters with various neck lengths. Implanted by orthopedic surgeons in clinical/hospital settings. Provides alternative to metal or alumina ceramic heads; improves wear characteristics and biocompatibility. Surgeon selects appropriate head size/neck length during surgery to restore joint function and stability.

Clinical Evidence

Bench testing only. Testing performed per FDA guidance documents for orthopedic implants, including metallic plasma sprayed coatings, non-articulating modular components, acetabular cup prostheses, femoral stem prostheses, ceramic ball hip systems, and UHMWPE data requirements.

Technological Characteristics

Material: Alumina matrix composite. Form factor: Modular femoral head, 28/32/36 mm diameters. Application: Total hip arthroplasty. Connectivity: None (mechanical implant). Sterilization: Not specified.

Indications for Use

Indicated for skeletally mature patients undergoing primary total hip replacement due to rheumatoid arthritis, traumatic arthritis, polyarthritis, collagen disorders, avascular necrosis, nonunion of femoral fractures, congenital hip dysplasia, protrusion acetabuli, slipped capital femoral epiphysis, previous fusion, or acute femoral neck fractures.

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.

## SUBSTANTIAL EQUIVALENCE

Aesculab Implant Systems, Inc. believes that the BIOLOX® delta Ceramic Femoral Head is a line extension of Aesculap Implant Systems Excia (K042344, K060918, and K062684) - Hip Systems and Metha Short Stem Hip System (K080584) that were previously cleared. It is also substantially equivalent to the Zimmer BIOLOX detta Ceramic Femoral Head (K071535).

## DEVICE DESCRIPTION

The Aesculap Implant Systems BIOLOX® delta Ceramic Femoral Heads are manufactured from an alumina matrix composite. The ceramic femoral head is offered in thee diameters of 28, 32, and 36 mm with a range of neck lengths. The BIOLOX® delta Ceramic head provides the surgeon another option to both the metal and alumina ceramic femoral heads for use in total hip arthroplasty.
