Is there any way to speed up the healing of fracture of phalanx of foot?

Depends. Generally, no. Closed foot phalanx fractures heal in a relatively predictable manner. There are no proven medications or other measures that will speed this up. However, there are some especially severe fractures and open fractures that will heal faster with surgery. There are also a very small number that will go on to nonunion. Nonunions need investigation and tailored treatment.
No. But there are ways of slowing it down like smoking or being overly active on it a good vit d level of >35 will help with healing.
Fracture. Not really - but , as stated it can be slowed by bad habits like smoking and poor diet. Some fractures heal better with surgery and a pin , etc. See your treating physician for any and all questions.
