Inion OTPS™ implants are manufactured from Inion® Polymer blends and have optimized handling properties, strength and degradation characteristics that support a more natural healing process. The Inion OTPS™ implants retain their strength while bone healing occurs and then gradually lose their strength between 18 and 36 weeks to progressively load the bone. Complete mass loss will occur within 2-4 years. The Inion OTPS™ implants degrade by hydrolysis and over a period of time are metabolised through natural processes in the body into carbon dioxide and water which are then exhaled and excreted.
Clinical benefits
The bioabsorbable Inion OTPS™ implants provide several clinical benefits to trauma and reconstructive orthopaedic procedures:
- Bone healing: maintenance of accurate alignment of
- bone fractures
- osteotomies
- arthrodesis
- bone grafts
with appropriate additional immobilization
- Avoidance of removal surgery, reducing patient trauma and cost
- No permanent implant left in the body reducing risk of implant migration and stress shielding
Additional benefits
The bioabsorbable Inion OTPS™ implants provide additional benefits due to their technical features and material composition:
- Resorbs in 2–4 years
- Predictable degradation progressively loads the bone to aid bone regeneration. The Inion OTPS™ implants maintain adequate strength during the healing period of fracture, osteotomy or other indicated procedure
- No long-term implant palpation, visibility, temperature sensitivity
- No imaging interference: no artifact is created on X-ray, computer tomography (CT) and magnetic resonance imaging (MRI) by the material
- No release or accumulation of metal debris, nor metal-induced allergies/sensitization
- Sterile-packaged implants reduce the risk of cross-contamination and overall infection risk
- Easier revision procedures: if re-operation is needed, the previously inserted Inion OTPS™ implants have either absorbed, or can simply be drilled through
- Inion OTPS™ pins have improved intraoperative visibility due to coloured implants
- Anatomic plate-screw construct: the Inion OTPS™ plates/meshes can be cut and contoured to any desired shape after water bath treatment during the operation
- The fully-threaded Inion OTPS™ screws can be trimmed to length
