Intended Use
The ATLAS® III Acetabular Cup is intended for use in degenerative and inflammatory arthritis of the hip joint, trauma, and revision of previously failed hip arthroplasties. The device is designed for cementless application.
Device Story
ATLAS® III Acetabular Cup; cementless hip prosthesis. Features 8 axial screw holes, 4 locking pegs for impaction anchoring, 1 dome hole for impaction verification, 2mm slot for stability. Available in 12 outer diameters (46-68mm); polyethylene inserts in 4 inner diameters (22.2-32mm). Used in orthopedic surgery; implanted by surgeon. Optional screw fixation determined intraoperatively. Polyethylene insert placed into shell post-impaction. Provides stable acetabular component for hip arthroplasty; restores joint function.
Clinical Evidence
Bench testing only. Data provided to characterize materials, hydroxylapatite coating, and performance characteristics under defined laboratory conditions.

Indications for Use
Indicated for patients with degenerative or inflammatory hip arthritis, trauma, or requiring revision of failed hip arthroplasties.
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.
