Intended Use

Biolox® delta Ceramic Heads are indicated for use in total hip replacement with cemented or non-cemented femoral and acetabular components in cases of 1) Non-inflammatory degenerative joint disease including osteoarthritis and avascular necrosis 2) Rheumatoid arthritis 3) Correction of functional deformity 4) Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement, unmanageable by other techniques. 5) Revision procedures where other treatment or devices have failed. Specific indications for compatible components that can be used with the above modular heads include: Salvage/Oncology Hip and Total Femur System components are also indicated for cases of ligament deficiency, tumor resection, trauma and revision of unsuccessful osteotomy or arthrosis. Interlocking hip stems are indicated for non-cemented application in cases of revision, trauma, fracture, oncology or other situations where severe proximal bone loss may compromise the fixation and stability of a standard type hip replacement prosthesis.

Device Story

Modular ceramic femoral head for total hip arthroplasty; highly polished spherical bearing surface articulates with polyethylene acetabular liner; attaches to metallic femoral stem via Type I taper. Used in surgical settings by orthopedic surgeons. Provides stable articulation for hip joint replacement; restores joint function; addresses degenerative disease, fractures, and revision needs. Device benefits include wear resistance and biocompatibility of ceramic material.

Clinical Evidence

No clinical data provided. Substantial equivalence supported by non-clinical bench testing in accordance with the 'Guidance Document for the Preparation of PreMarket Notifications for Ceramic Ball Hip Systems'.

Technological Characteristics

Modular ceramic femoral head; spherical bearing surface; Type I taper connection to metallic femoral stem. Available in 28mm and 32mm diameters with varying neck lengths. Materials and design meet FDA guidance for ceramic ball hip systems.

Indications for Use

Indicated for patients requiring total hip replacement due to non-inflammatory degenerative joint disease (osteoarthritis, avascular necrosis), rheumatoid arthritis, functional deformity, non-union, femoral neck/trochanteric fractures, or revision procedures. Compatible with specific Salvage/Oncology and Interlocking hip systems for ligament deficiency, tumor resection, trauma, or severe proximal bone loss.

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.
