Intended Use
The APR® Fully Textured Hip Stem is intended for prosthetic replacement of the proximal portion of the femur in a hip replacement.
Device Story
Nonporous, anatomic femoral component for hip arthroplasty; replaces proximal femur. Manufactured from Ti-6Al-4V alloy; features full-length surface texturing for cemented or press-fit fixation. Design includes anterior angulation, double-wedge proximal body, 12/14 Morse taper for modular heads, and circular distal cross-section. Larger sizes include distal cylindrical hole for increased flexibility. Used by orthopedic surgeons in clinical/OR settings. Provides stable femoral fixation; facilitates joint reconstruction; restores hip function.
Clinical Evidence
Bench testing only.
Technological Characteristics
Material: Wrought Ti-6Al-4V alloy (ASTM F 136). Design: Nonporous, anatomic femoral stem with full-length surface texturing. Features: 12/14 Morse taper, anterior angulation, double-wedge proximal body, circular distal cross-section, distal cylindrical hole for flexibility. Configuration: Left and right versions in multiple sizes. Energy source: None (mechanical).
Indications for Use
Indicated for patients requiring prosthetic replacement of the proximal femur during hip replacement surgery.
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.
