Periprosthetic Fracture is a complex condition that is attached with multiple classifications. The type of implant that will be organized for the condition depends on the pattern of the fracture. The classifications are critically differing from stability to instability as the condition of bones often arouses risks and chronicity of implantation. In today’s time, surgeons are quite fallen into dilemma due to inside fractures after the surgery.


The classifications are also dependent on the location, displacement, and implant stability. Although, the classifications label location proximal to distal and complexity increases as fractures move distally. Most classification systems subclassify “A” as nondisplaced and “B” as displaced fractures.


The type 1 fractures are defined to the proximal femur, whereas the type 2 fractures are defined around the stem. There is one more type that is type 3 which occurs below the tip of the prosthesis.

After the diagnosis is conducted, the procedure for treatment is figured out. Usually, the people suffering from this fatal condition are elderlies and fragile individuals who require intensive care as the rate of mortality increases. Hence, the doctor focuses on nonoperative as well as operative interventions. Another, the latest procedure is TKA which allows firm fixation in the majority of cases.





The Periprosthetic Fracture is a rapidly growing condition that is acquired by 26 people out of 10,000 persons.
