I'm sorry to have to tell you that you're unlikely be able to anything for your betta at this point. Once fish have developed a bent body like that, they're beyond help, tbh
 
You could try; doing a large water change, lowering the water level (you might have to move the filter down, or put it on it's side so it still works), raising the oxygen levels (either by adding an air stone or by raising the filter slightly so it creates a lot more movement at the water surface) and raising the temperature to around 27°C/80°F, if it's lower.

Thank you for your answer.I tried everything you said.Unfortunately it was too late.Larry the betta passed away an hour after i read your answer.We put him in mini wooden casket and cremated him in a fire.R.I.P Larry.
