the healing of a fractured bone depends on many factors. 1. type of fracture - compound fractures - take much longer to heal. 2. displaced bone fragments - if the bone edges and parts have been displaced then the risk of delayed union and nonunion increase. 3. infection - increases the healing time. 4. disruption of the blood flow to the fracture site - also hampers healing 5. malnutrition bone disorders also prolong the healing time. 6. early mobilization of the joint - before complete healing. in your case you have 2 or more factors which have caused the delay in your recovery. without first hand knowledge of your current condition examination of your xrays and a physical examination it would not be possible to give exact possibility of your prognosis. i am sorry about that. but platelet rich plasma (prp) does contain important cytokines and growth factors which when injected into a injured area helps to improve the rate of healing (bone formation in your case) and hence your recovery. as mentioned in your history you may already might have had some progress. hence if the fractured bone site heals completely (which will eventually happen in due time) - there is no doubt that you will be able to walk normally on the affected foot. i hope this helps.
i am 26 years old. i had met an motor-bike accident 1 year ago where i fracture my right leg. it was a kind of simple open compound fracture. surgery was done & nail/ rod were placed there. i have followed the doctor & do every things he said but bone healing doesn't occur. instead the nail start breaking after i start walking without crutches. the doctor added extra calcium supplements & waited further. but no changes. then i move to next hospital. after 8 month a prp injection was given saying it was a non-union & waited to see the reaction. no good changes. then after 11 month again surgery was done replacing the broken nail with another long & wider nail/rod. some changes were observed within 4 months. then dynamization of nailing along with prp inject was made recently. will it solve the problem? what are the chances? how long it will take to heal? can i walk without support as it has been 4 month already(except recent dynamization)?
