Intended Use / Indications for Use
Components of the Inter-Op HA Porous Acetabular System are intended to replace the acetabulum during total hip arthroplasty. The four metallic shell styles are porous coated and used in conjunction with a snap-in polyethylene liner. The acetabular components of this system are intended to achieve biological fixation to bone without the use of bone cement.
While three of the shell styles are hemispherical, the Protrusio HA Porous Shell is designed to compensate for protrusio defects where there has been thinning of the medial and superior walls of the acetabulum. The inner diameter is hemispherical while the outer shell has a 10mm build up, thus maintaining the anatomical hip center and avoiding the medialization of the femoral component.
Diagnostic indications for use of components of the Inter-Op HA Porous Acetabular System include:
- revision of a previously implanted acetabular prosthesis;
- patient conditions of noninflammatory degenerative joint disease; e.g., avascular necrosis, osteoarthritis, or arthritis secondary to a variety of diseases and anomalies; and,
- inflammatory joint disease; e.g., rheumatoid arthritis.

Device Description
The Inter-Op™ HA Porous Acetabular System consists of a Ti-6Al-4V alloy (ASTM F136) shell which utilizes a polyethylene snap-in liner. Hydroxylapatite (HA) coated Cancellous Structured Titanium™ (CSTi™) porous coating provides biological fixation in a cementless application. The shells are available in a variety of sizes and designs to address different clinical situations in both primary and revision arthroplasties. Inter-Op HA Porous Acetabular Components are recommended for use with all Sulzer Orthopedics total hip replacement devices.
The system includes two primary designs: (1) a hemispherical shell with an offset outer radius in the rim region, which permits the loads to be transmitted to the periphery of the outer surface; and (2) a hemispherical shell with two plugged screwholes. The plugs may be removed intraoperatively for additional screw fixation, if desired. A dome hole plug is also provided.
Two multi-holed shells designed for screw application are provided for those clinical situations in which deficient bone stock exists in the acetabulum. Those screwholes that are not utilized may be plugged after implantation. This shell is available in two designs: (1) a standard hemispherical cup, and (2) a protrusio cup which adds 10mm of thickness of the medial wall over a standard hemispherical cup to address protrusio deficiencies in the acetabulum. A dome hole plug is also provided.
All the shell designs share identical internal geometry and locking mechanism thereby accepting any of the acetabular liners designed for this system. The acetabular liner is manufactured from Ultra-High Molecular Weight Polyethylene, or UHMWPE (ASTM F648) and is offered in various configurations in order to address different clinical situations. The liners are also available in a variety of sizes to accommodate available femoral head components.

(a)
Identification. A hip joint metal/polymer/metal semi-constrained porous-coated uncemented 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 has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy or a titanium-aluminum-vanadium (Ti-6Al-4V) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The femoral stem and acetabular shell have a porous coating made of, in the case of Co-Cr-Mo substrates, beads of the same alloy, and in the case of Ti-6Al-4V substrates, fibers of commercially pure titanium or Ti-6Al-4V alloy. The porous coating has a volume porosity between 30 and 70 percent, an average pore size between 100 and 1,000 microns, interconnecting porosity, and a porous coating thickness between 500 and 1,500 microns. The generic type of device has a design to achieve biological fixation to bone without the use of bone cement.(b)
