Do u have any problem with implant

Is there any problem associated with this implant now??

For an accurate diagnosis, a detailed assessment with clinical examination and proper history followed by appropriate investigations is needed.

If u want, u can go for that screw removal.once seek the opinion from surgeon who did it.

You have one of the fracture which is known to go in to Nonunion. Fortunately your orthopaedic surgeon had done commendable job and fracture is healing but Not consolidated enough to take out implant. If it really troubling you like skin irritation or tingling down inner aspect of forearm/or infection then only think of implant removals otherwise follow the advise given by operating surgeon
