![]() ![]() ![]() ![]() Press-fit osseointegration usually provides superior mobility and quality of life compared with nonoperative and other operative options for patients expressing dissatisfaction for reasons such as those mentioned above, including poor fit, compromised energy transfer, skin pinching, compression, and abrasions. Press-fit osseointegration can be provided for amputees having difficulty with socket wear 5. An alternative design is a screw-type osseointegration implant 1. Non-osseointegration surgical options to try to improve socket fit include bone lengthening and/or soft-tissue contouring. Alternatives:Īmputees who are dissatisfied with their quality of life or mobility when using a socket prosthesis can attempt to modify their socket or activity level or accept their situation. The preoperative evaluation is summarized and the specific surgical steps are described: exposure, osteotomy, canal preparation, implant insertion, (optional) targeted muscle reinnervation, muscle closure, soft-tissue contouring and stoma creation, and abutment insertion. We demonstrate the fundamentals of a single-stage procedure involving an impacted press-fit porous-coated titanium osseointegration implant. Amputees with osseointegrated prostheses typically wear their prosthesis more and experience better mobility, quality of life, and extremity proprioception compared to those with socket prostheses 2 - 4. This allows the prosthesis to be skeletally anchored, eliminating socket-related problems such as tissue compression that can provoke neurogenic pain, skin abrasion, and fitting problems resulting from residual limb size fluctuation 1. Press-fit transfemoral osseointegration is the technique of inserting an intramedullary metal implant into the residual femur of an amputee the implant is passed transcutaneously to attach to a standard prosthesis that includes a knee, tibia, ankle, and foot. ![]()
