Intended Use

BonOs® HV Genta, BonOs® MV Genta and BonOs® LV Genta are intended for the fixation of prothesis to living bone in the second stage of a two-stage revision for total joint arthroplasty after the initial infection has been cleared.

Device Story

BonOs® HV/MV/LV Genta are radiopaque PMMA bone cements containing gentamicin; designed for fixation of prostheses to living bone. Device consists of two sterile components: powder (polymer, initiator, radiopacifier, antibiotic) and liquid (monomer, activator). Components are mixed intraoperatively to create a self-hardening cement that fixes implants and transfers stresses to bone. Used by orthopedic surgeons in clinical settings during revision arthroplasty. Output is a hardened cement structure providing mechanical fixation. Benefits include stable implant fixation and localized antibiotic delivery to aid in managing post-infection revision scenarios.

Clinical Evidence

Bench testing only. No clinical data provided. Performance testing included mixing/application characteristics, chemical composition, molecular weight, physical/thermal properties, and mechanical testing (cyclic fatigue, bending, compression, tension, fracture toughness). Results demonstrate compliance with ASTM F451-16, ISO 5833:2002, ISO 527:1/2, ASTM F2118-14, ASTM D2990-17, ASTM D732-17, and ASTM E399-20. Biocompatibility evaluated per ISO 10993-1. Bacterial endotoxin testing met USP <161> limits.

Technological Characteristics

PMMA bone cement; two-component system (powder/liquid). Powder: polymer, benzoyl peroxide initiator, zirconium dioxide radiopacifier, gentamicin sulfate. Liquid: methylmethacrylate monomer, N,N-Dimethyl-p-toluidine activator. Sterilization: Ethylene oxide. Complies with ASTM F451-16, ISO 5833:2002, ISO 527:1/2, ASTM F2118-14, ASTM D2990-17, ASTM D732-17, ASTM E399-20, and ISO 10993-1.

Indications for Use

Indicated for patients undergoing the second stage of a two-stage revision for total joint arthroplasty following the clearance of an initial infection.

The predicate devices are as follows:

- Rally™ HV AB Bone Cement (510(k) application K143100)
- Palacos® R+G (510(k) application K031673)

### 4. Device Description

BonOs® HV Genta, BonOs® MV Genta and BonOs® LV Genta are PMMA, radiopaque bone cements, containing gentamicin, designed for the fixation of prothesis to the living bone. BonOs® HV Genta, BonOs® MV Genta and BonOs® LV Genta are traditional bone cement products. The bone cement is made of two separate sterile components. When both components are mixed together, they become a self-hardening, radiopaque bone cement which fixes the implant and transfer stresses evenly to the bone. The liquid is contained in a vial and the powder in a pouch; these components are packed in blister with Tyvek lid or an aluminium pouch. The devices are sold disposable, singleuse and sterile.

### 5. Indication for Use

Below is the indication for use:

BonOs® HV Genta, BonOs® MV Genta and BonOs® LV Genta are intended for the fixation of prothesis to living bone in the second stage of a two-stage revision for total joint arthroplasty after the initial infection has been cleared.

### 6. Comparison of the technological Characteristics with the Predicate Device

BonOs® HV Genta, BonOs® MV Genta and BonOs® LV Genta share many of the same technological characteristics compared to the predicate Rally™ HV AB Bone Cement, including important considerations such as materials, mechanical performance and chemical-physical performances, for this reason, a second predicate (Palacos® R+G) was included.
