• Device Name: ALUMINA HEAD
• Applicant: Fournitures Hospitalieres Industrie
• Product Code: LZO · Orthopedic
• Decision Date: Nov 17, 2004
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 888.3353
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

Prosthetic replacement of the femoral head associated with a hip prosthesis having a taper compatible with the head taper, and with a prosthetic acetabulum having an inside diameter compatible with that of the head. The alumina head can only be used with polyethylene inserts. This prothesis may be used for degenerative joint disease such as osteoarthritis and avascular necrosis, correction of functional deformity, rheumatoid arthritis, revision procedure where other devices or treatments have failed, congenital dislocation, femoral neck fractures, traumatic arthritis, fused hip, diastrophic variant, slipped capital femoral epiphysis, non-union.

Device Story

Alumina femoral heads serve as prosthetic replacements for the femoral head in hip arthroplasty. Fabricated from Biolox forte alumina, these heads feature a 12/14 cone taper and are available in 28mm and 32mm diameters with varying offsets (-3.5, 0, +3.5). The device is intended for use by orthopedic surgeons in clinical settings during hip replacement or revision surgeries. The head articulates with a compatible prosthetic acetabulum containing a polyethylene insert. By providing a durable, biocompatible bearing surface, the device restores hip joint function and mobility for patients suffering from degenerative or traumatic joint conditions.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included fatigue testing and static compression testing to rupture, as well as static compression testing at 2000 N and measurement of head extraction force. All results met FDA requirements.

Technological Characteristics

Material: Biolox forte alumina (ASTM F 6474). Geometry: 12/14 cone taper, 28mm and 32mm diameters, offsets of -3.5, 0, +3.5. Energy source: None (mechanical). Connectivity: None. Sterilization: Not specified.

Indications for Use

Indicated for patients requiring prosthetic femoral head replacement due to degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, congenital dislocation, femoral neck fractures, traumatic arthritis, fused hip, diastrophic variant, slipped capital femoral epiphysis, non-union, or revision procedures where prior treatments failed. For use with compatible hip prosthesis tapers and acetabular components with polyethylene inserts.

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.

## DEVICE DESCRIPTION:

Image /page/0/Picture/18 description: The image shows a logo with the word "SHITEM" written in a bold, sans-serif font. Above the word, there is a stylized graphic that resembles a distorted or abstract letter "S" or a pair of curved shapes facing each other. The graphic is enclosed within a square border, giving the logo a structured and contained appearance. The overall design is simple, yet distinctive, suggesting a modern and potentially corporate identity.

Alumina heads are made of Biolox forte alumina (trademark of CERAMTEC) according to ASTM F 6474 standard.

Alumina heads have a 12/14 cone and are available in two diameters: 28mm and 32mm, with three offsets: -3.5; 0; +3.5.

## INDICATIONS FOR USE:

Prosthetic replacement of the femoral head associated with a hip prosthesis having a taper compatible with the head taper, and with a prosthetic acetabulum having an inside diameter compatible with that of the head.
