Intended Use

The MPF Acetabular Cup Generation 2 is intended for uncemented use for all types of arthrosis, such as advanced destruction of the hip joint due to degenerative, post-traumatic or rheumatoid arthritis, fracture or avascular necrosis of the femoral head, sequelae of previous operations, such as internal fixation, joint reconstruction, arthrodesis, hemiarthroplasty or total hip replacement. The same considerations apply to acetabular revisions.

Device Story

The MPF Acetabular Cup Generation 2 is an orthopedic hip prosthesis component designed for uncemented fixation. It serves as a replacement for the acetabulum in total hip arthroplasty or revision procedures. The system includes standard cups (without screw holes) and revision cups (with screw holes), along with various polyethylene (PE) inserts for 28 mm and 32 mm ball heads. Sterile cancellous bone screws are provided for fixation. The device is implanted by orthopedic surgeons in an operating room setting. It functions by providing a stable, semi-constrained interface for the femoral head, restoring joint function and mobility in patients with advanced hip joint destruction. The modification expands the size range and insert options compared to the predicate device to accommodate a broader range of patient anatomies.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Acetabular cup prosthesis for uncemented use. Components include metal cups, polyethylene (PE) inserts, and cancellous bone screws. Available in multiple sizes (46-72 mm). Sterile packaging for screws. Design is semi-constrained.

Indications for Use

Indicated for patients requiring hip arthroplasty due to arthrosis (degenerative, post-traumatic, rheumatoid arthritis), femoral head fracture, avascular necrosis, or sequelae of prior hip surgeries (internal fixation, reconstruction, arthrodesis, hemiarthroplasty, total hip replacement). Also indicated for acetabular revisions.

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.
