It depends on angle
If it was a simple fracture
and the bone was in good alignment, let it heal on its own.
If it was significantly displaced or angulated, a surgical reduction may be needed..But it is now 13 wks out, it is certainly healed/sealed back. So, if xray shows good angle/alignment, you are set, especially if no pain and doing well.
Follow up with your ortho for consult if need be..
