• Bone-anchored prostheses are transcutaneous osseointegrated implant systems designed for amputees who have major functional problems with conventional socket prostheses. — Non-infectious skeletal complications in the lower extremity after treatment with a transfemoral bone-anchored prosthesis: a retrospective observational study
• The OPRA system has been in use since the 1990s and is considered a stable, well-fixated implant system. — Non-infectious skeletal complications in the lower extremity after treatment with a transfemoral bone-anchored prosthesis: a retrospective observational study
• The OPRA procedure requires two surgical stages: Stage 1 places the fixture, and Stage 2 inserts the abutment 3–6 months later after bone integration. — Non-infectious skeletal complications in the lower extremity after treatment with a transfemoral bone-anchored prosthesis: a retrospective observational study
• The Axor II safety device is designed to protect the osseointegrated implant parts when excessive forces act on the external prosthesis. — Non-infectious skeletal complications in the lower extremity after treatment with a transfemoral bone-anchored prosthesis: a retrospective observational study
• The OPRA system is designed so that excessive loading preferentially damages exchangeable abutment components rather than the osseointegrated fixture itself. — Non-infectious skeletal complications in the lower extremity after treatment with a transfemoral bone-anchored prosthesis: a retrospective observational study
• BAPs can improve physical function, prosthetic use, and quality of life by avoiding socket-related pain and skin problems. — Non-infectious skeletal complications in the lower extremity after treatment with a transfemoral bone-anchored prosthesis: a retrospective observational study
• Earlier OPRA research found that 29% of patients required abutment or abutment screw exchange within 5 years due to implant fractures. — Non-infectious skeletal complications in the lower extremity after treatment with a transfemoral bone-anchored prosthesis: a retrospective observational study
• Prospective studies of transfemoral OPRA implants reported only 17% revision-free survival for mechanical complications after 10 years. — Non-infectious skeletal complications in the lower extremity after treatment with a transfemoral bone-anchored prosthesis: a retrospective observational study
