Understanding The Causes Of Implant Failure

The success of an orthopedic implant depends on multiple factors, such as surgical technique, implant (mechanical properties of implant material, shape, and size), and patient factors (such as adjacent bone quality).1 However, some patients may encounter implant failure.2 Orthopedic implant failure occurs when the implant bonds poorly to the bone cells.2 Implant failure can potentially increase the morbidity rate, delay the healing process, and increase the hospital stay and health-cost burden.3

Your orthopedic surgeon will inform you about the possible implant-related complications before you undergo the procedure.  

The demand for better orthopedic implants has caused significant advances in the field, resulting in implants with better performance and novel properties.8

Some of the common challenges include:

Implant Infection:

Implant infections are a major concern in orthopedic surgery. The bacteria residing on the skin and inside the body can lead to infection after implant surgery.4

Implant Breakage:

Implant breakage or fracture can be caused due to non-union of a fractured bone, failure to comply with prescribed post-operative instructions, recurring trauma, and bacterial infections at the surgical site.5

Implant Loosening:

Implant loosening can be caused due to bearing of excessive weight before the fracture has healed completely.6 The other causes include surgical technique, lower bone quality, lesser biocompatibility of implant, inadequate bone remodeling, and infection.7
