Non-cemented femoral stem revision with OssGro® granules and Ossfinity®
A 16 year old patient underwent total hip arthroplasty following epiphyseal slippage. Eight years after the primary surgery, doctors observed a gradual loosening of the femoral stem.
Diagnosis and treatment
During the revision surgery a trochanteric osteotomy was performed to increase the stability of the new implant. OssGro® granules were used to ﬁll the space between the residual bone and the revision stem with Ossﬁnity® putty securing the granules in place. The use of Ossﬁnity® ensured proper bone regeneration in the femoral metaphysis.
After ﬁve months, the patient had fully recovered and was pain free. As shown in the post-operative X- ray, the new revision stem was stable and regenerated bone can be observed in the remodeled implant area. The OssGro® granules and Ossﬁnity® putty ﬁlled the spaces between the bone and implant perfectly, providing stability.
