Intended Use

The IntraBlock™ BioBall™ Hip System (IBS) is intended for use in total hip arthroplasty. The IBS is indicated for: - Patients suffering from severe hip pain and disability due to rheumatoid arthritis, osteoarthritis, traumatic arthritis, - Avascular necrosis of the femoral head, - Correction of functional deformity, - Treatment of non-union, femoral neck fracture and trochanteric fractures of the proximal femur with head involvement, unmanageable by other techniques, - Revision procedures where other treatment or devices have failed. The IBS is indicated for cementless use only.

Device Story

Total hip arthroplasty system comprising femoral stems, heads, taper adapter sleeves, and acetabular cups. Designed for cementless primary or revision hip replacement. Components include Biolox® delta ceramic heads and titanium alloy (Ti-6Al-4V ELI) acetabular cups with titanium plasma spray coating and UHMWPE inlays. Used by orthopedic surgeons in clinical settings to replace damaged hip joints. Provides structural support and articulation for the hip joint; restores mobility; reduces pain. Surgeon selects appropriate component sizes and secures the cup via press-fit, with optional locking screws for additional fixation.

Clinical Evidence

Bench testing only. Mechanical testing included modular connection analysis (fretting, corrosion, static compression/burst testing), wear testing, coating characterization, and range of motion analysis. Testing followed guidance for ceramic ball hip systems.

Technological Characteristics

System components: femoral stems, heads, taper adapter sleeves, acetabular cups. Materials: Biolox® delta (Alumina Matrix Composite ISO 6474-2) for heads; titanium alloy (Ti-6Al-4V ELI, ASTM F-136) for cups with titanium plasma spray coating; UHMWPE inlays. Cementless fixation. Modular design.

Indications for Use

Indicated for patients with severe hip pain/disability due to rheumatoid arthritis, osteoarthritis, traumatic arthritis, avascular necrosis, functional deformity, non-union, femoral neck/trochanteric fractures, or revision needs. For cementless use only.

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:

The IntraBlock™ BioBall™ Hip System (IBS) is composed of femoral stems, heads, taper adapter sleeves and acetabulum cups. The System is designed for uncemented use for either primary or revision hip arthroplasty.

The Ceramic Head is made of Biolox® delta (Alumina Matrix Composite ISO 6474-2) and available in diameters 28, 32 and 36 mm.

The cementless MultiCup Locking PressFit is manufactured from titanium alloy (Ti-6Al-4V ELI) conforming to ASTM F-136 with a titanium plasma spray (TPS) coating on the outer surface. It is used with a UHMWPE Inlay sized for Ø28, 32 and 36 mm heads. 5 holes with threaded plugs give the option for an additional fixation with locking screws. The MultiCup is available in 9 different sizes ranged from 46 mm, 48 mm up to 62 mm outer diameter.

### Legally marketed Devices to which substantial Equivalence is claimed

K123619 - IntraBlock™ BioBall™ Hip System (IBS) K073567 - Biolox® delta Option Ceramic Heads K001534 - Pinnacle™ Acetabular Cup K000306 - Pinnacle™ Acetabular Cup K093472 - Trinity Acetabular System

## Non-Clinical Performance Data:

Non-clinical testing and analysis were provided to support substantial equivalence. Mechanical testing included testing of the modular connection, wear testing and mechanical testing of the coating as well as coating characterization. Range of Motion analysis also was performed.

The modular connection analysis included fretting and corrosion as well as static compression testing (burst testing and post-fatigue burst testing) consistent with the "Guidance document for the preparation of premarket notifications for ceramic ball hip systems". Furthermore the connections between the stem, the adapter and the head, as well as the liner locking mechanism were tested in pull-off, rotation testing and cup/liner disassembly testing.
