Indications for Use
The Taper 2™ Porous Femoral Stem is indicated for use in patients requiring total hip replacement due to the following: Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis; Rheumatoid arthritis; Correction of functional deformity; Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement, unmanageable by other techniques; Revision of previously failed femoral head resurfacing component. Taper 2™ Porous Femoral Stems are intended for uncemented use only.
Device Story
Taper 2™ Porous Femoral Stem is a short, tapered femoral component for total hip arthroplasty. Device is implanted into the femur during hip replacement surgery to restore joint function. It is designed for uncemented fixation. The stem is used in conjunction with modular heads and acetabular components. It is intended for use by orthopedic surgeons in a clinical/hospital setting. The device provides structural support and stability for the hip joint, aiming to alleviate pain and restore mobility in patients with degenerative joint disease, arthritis, or fractures. Clinical benefit is derived from the restoration of hip joint function and stability.
Clinical Evidence
No clinical data provided. Substantial equivalence is supported by bench testing and reference to performance data of predicate femoral hip stems.
Technological Characteristics
Short, tapered femoral stem designed for uncemented fixation. Materials and manufacturing processes are consistent with predicate devices. The device is a component of a modular hip prosthesis system.
Indications for Use
Indicated for patients requiring total hip replacement due to non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, or proximal femur fractures/non-union unmanageable by other techniques. Intended for uncemented use in skeletally mature individuals.
Regulatory Classification
Identification
A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).
