The goal of modern orthopedic is to obtain the anatomical union of fracture and give a good functional return of the patient. To obtain this, it requires rigid internal fixation by using an appropriate implant. The success of internal fixation depends on multiple factors. Implant failure often lengthens the healing process, leads to re-fractures and increase the cost for the patients. It often requires additional complicated surgeries. This shows the importance of exploring causes of implant failure.1
Implant failure can result from faulty implants or external factors such as surgeons experience and adherence to AO principles, improper type of implant for particular fracture type and non-compliance of the patients with post-operative instructions, particularly weight bearing in lower limbs surgery.2, 3 Patients with implant failure usually present with pain and deformity of the operated limb. It may or may not be related to a recent trauma.4
Revision surgery is always challenging to an orthopedic surgeon because the tissues are scared and removal of broken implants are always difficult. Also, there is a high chance of neurovascular injury and post-operative infection.5, 6 Few studies have demonstrated that quality of implant as the main cause of implant failure.7, 8 Other studies have shown that early weight bearing may be the cause of early implant failure.9
In our study, we have focused on mechanical and biological causes i.e., the pattern of fracture, proper used of the implant, adherence to AO trauma surgery principles and post-operative weight bearing. We are of the opinion that combination of two or more than two of these causes leads to early implant failure. Hence this study was designed.
The purpose of this study was to identify a possible cause of implant failure, which is being used in our setup for fixation of different fractures. The intent of this research was to determine the reasons for implant failures and prevent the failures.
