Hello doctor, I had a Hawkins type 2 talus fracture to my talus bone 8 years back and I was operated with surgery by bringing the broken bone together with screws.. It took nearly 1 year for me to able to walk normally again after the fracture and they removed the screws later after 6 months But of late i feel that my bone is getting weaker when ever I climb stairs or do any physical activity other than normal walking.. Couple of years back i met the doctor who did my surgery and he suggested me an ankle fusion if it gets more worser I am curious to know what other options do i have i read there are methods like core decompression to regain the blood supply to talus but if there is arthritis will it work? Thank u
