Intended Use

All Exactech Hip Systems are indicated for use in skeletally mature individuals undergoing primary surgery for hip replacement due to osteoarthritis, rheumatoid arthritis, osteonecrosis, post-traumatic degenerative problems of the hip, and for treatment of proximal femoral fractures where prosthetic replacement is determined by the surgeon as the preferred treatment. Components of Exactech Hip Systems are also potentially indicated for ankylosing spondylitis, congenital hip dysplasia, revision of failed previous reconstructions where sufficient bone stock is present, and to restore mobility resulting from previous fusion. Cemented femoral stems and cemented acetabular cups are intended for cemented fixation only. Press-fit femoral stems and acetabular cups are intended for press-fit fixation. Press-fit components without hydroxyapatite (HA) coating may also be used with bone cement at the discretion of the surgeon. Femoral heads and endoprostheses are intended for use in cemented and press-fit applications.

Device Story

AcuMatch and Novation Cemented Femoral Stems are orthopedic implants for hip arthroplasty. These devices replace the femoral head and neck to restore joint function. Modifications include transition to '12/14 Euro-Style' threadform tapers, adjusted neck lengths/geometry, and updated insertion hole features. L-Series stems transitioned from cast to forged Co-28Cr-6Mo. Novation stems feature modified cross-sectional geometry. Used by orthopedic surgeons in clinical settings for hip replacement procedures. Implants provide structural support and articulation for the hip joint, aiming to restore patient mobility and reduce pain. Performance verified via empirical testing and engineering analysis.

Clinical Evidence

Bench testing only. Engineering evaluations and empirical testing were conducted to verify that the performance of the modified femoral stems is adequate for anticipated in vivo use.

Technological Characteristics

Materials: Co-28Cr-6Mo (ASTM F75 cast or ASTM F799 forged). Design: Cemented femoral stems with 12/14 Euro-Style threadform taper. Features: Oblong insertion slot, laser-etched taper face, circulo-trapezoidal cross-section (Novation). Sterilization: Not specified.

Indications for Use

Indicated for skeletally mature individuals requiring primary hip replacement due to osteoarthritis, rheumatoid arthritis, osteonecrosis, post-traumatic degeneration, or proximal femoral fractures. Also indicated for ankylosing spondylitis, congenital hip dysplasia, and revision of failed reconstructions with sufficient bone stock. Contraindicated in patients with active infection, insufficient bone stock, neuromuscular disorders preventing joint control, or conditions expected to cause early implant failure.

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.
