Results: 305 Revision were total hip arthroplasty replacement surgeries between the years 2006 2013. Endoscopic visualization and pneumatically-powered ballistic chisels in 45 cases were used. Average age of these patients was 67.4 and most of the femoral bone defects were scored as Paprosky type 1,2a (45%). It was able to use primary stem even for revision purposes in 45% of patients, thanks to minimal bone damage. Transfemoral approach had to be used only in two cases.

Ballistic-powered chisels can effectively remove femoral components in 45% of total hip arthroplasty revision cases, allowing minimal bone damage and allowing primary stem use in 45% of patients.

Femoral component removal with the assistance of ballistic powered chisel, 9-years experiences

Key Takeaway: Ballistic-powered chisels can effectively remove femoral components in 45% of total hip arthroplasty revision cases, allowing minimal bone damage and allowing primary stem use in 45% of patients.
