Constructing an Osseointegrated Prosthetic Leg

Area of Science:

• Orthopedic Surgery
• Prosthetics and Orthotics
• Biomedical Engineering

Background:

• Osseointegrated prosthetic leg construction follows surgical implantation of a bone-anchored transcutaneous implant.
• This procedure is considered for patients with poor outcomes or dissatisfaction with socket prostheses.

Purpose of the Study:

• To describe the techniques and principles for constructing osseointegrated prosthetic legs for transfemoral and transtibial amputees.
• To outline preoperative, postoperative, and long-term patient care protocols.

Main Methods:

• Preoperative patient evaluation by a prosthetist within a multidisciplinary team.
• Postoperative implant inspection, measurements, and temporary loading implant placement.
• Evaluation of implant and prosthetic quality, including alignment and dynamic function, before full weight-bearing.

Main Results:

• Osseointegration provides superior mobility and quality of life compared to socket prostheses.
• Allows function for patients with short residual limbs unsuitable for sockets.
• Potential complications include infection and periprosthetic fractures, generally manageable with established treatments.

Conclusions:

• Osseointegration offers significant advantages in prosthesis wear time, mobility, and quality of life.
• Proper prosthetic design and alignment are crucial for optimal outcomes and injury prevention.
• Long-term patient care and prosthetic maintenance are essential for sustained function.
