How to proceed with a displaced hip prosthesis at 67?

Hello doctor,

My mother, aged 67, got her hip joint fractured. She got operated on and an InterTan nail was implanted. But the nail part got displaced from the hip side and is now touching the hip bone, causing pain. She is weak, has low bone density, and suffers from other diseases as well (rheumatoid arthritis, glaucoma, hypothyroidism, hypertension, and asthma). What should be the next course of action? Will new bone formation occur if plaster is used, or does she need joint replacement? Will plaster worsen her situation? How safe will a joint replacement be at her age, and what will be the implications in the future? Which one will be beneficial for her, considering her overall health status? Please suggest the best way forward.

Thank you, doctor,

The hip joint replacement has been performed by the doctor here, but we could see a fracture in the X-ray report. We are clueless now about what to do next. Does she require bed rest now and to wait for the fracture to heal? Is she able to start with minor load-bearing physiotherapy? Please advise the best possible next action for her. How to proceed with her treatment now? I am attaching her latest X-rays.

Hello doctor,

Thank you a lot for answering my queries. A few more things I would like to understand here. Is there any possibility for the fracture to heal if we go for bed rest for a month, or if we start with partial load bearing? Should we wait for a month and let the bone adjust to the current implant and strengthen the bone with a calcium-rich diet so that further complications can be avoided? What will happen to fracture if it will not heal, will that remain like that forever? Will it create any discomfort or pain for my mother in the long run or any future complications at any level (nerve damage) due to this fracture?
