Methods
Between March 2015 and June 2018 a total of 90 patients were included from lower amputees referred for bone anchoring surgery to the Radboud UniversityNijmegen in the Netherlands. 53 persons received a BADAL: X standard femur stem (OFI-C), 16 persons received a BADAL X short femur stem with collumscrew (OFI-Y) and 21 persons received a BADAL X tibia stem (OTI). The adverse events were recorded from the medical charts and Prosthetic Use Score (PUS)and the quality of life Global Score (GS) were assessed with the Questionnaire for Persons with a Transfemoral Amputation (Q-TFA).
Results
Implant survival was 94,2% (OFI-C = 93.8%, OFI-Y = 93.3%, OTI = 95.5%). Five implants were removed; one because of a periprosthetic fracture, two becauseof septic loosening and two because of unexplained pain. Periprosthetic fracture occurred in four patients and all were treated surgically, three with fixation,one with implant removal. Baseline Q-TFA-PUS and GS scores increased significantly in all patients. PUS improved with 58% (58 at baseline with socketattachment and 83 at 5 yrs FU with bone anchoring). GS improved with 68% (40 at baseline with socket attachment and 67 at 5 yrs FU with bone anchoring).
Conclusion
Contemporary BADAL X press-fit titanium bone anchoring system, when used in lower limb amputations, result in
acceptable rates of survival and safety, with considerable improvements in functional outcomes.
