The unique distribution of calcium salt throughout the Little Grafter provides strength and bone bonding to ensure effective integration with surrounding bone. A patented process ensures HA particles are on the surface of the device for early cellular attachment
The first Bioactive Mini Screw
Osteoblast bone forming cells attach directly to the HA within the LG screw providing immediate
biological fixation.
Direct bone apposition increases fixation strength and reduces the risk of implant migration, especially in a cyclically loaded environment
The bioactive nature of the material provides an osteoconductive scaffoid for bone cell proliferation and migration across the
fracture site to facilitate healing.
Proven Material that is modulus matched
The calcuim throght the LG screw provides a pH buffer against the acidic degradation of the polymer preventing the risk of acidosis.
To date Biosteon, the material from which Little Grafter is manufactured, has been implanted in over 100 000 patients in the form of an ACL Screw, without a single reported case of an adverse tissue response.
The composite nature of Biosteon provides the Little Grafter close modulus matching to bone. Non-modulus matched metals may cause stress
shielding within the bone, leading to loosening of the implant and a reduction of local bone
density which can be problematic in fracture fixation
Indications:
Scaphoid, Carpal fractures and fusions
