How long it takes for a thumb fracture to be able to flex and extend depends on the location of the finger and the fracture, as well as the healing time of the fracture. If the fracture is only to the distal end of the thumb, it can be rested for another 3-4 weeks, and the local joint can be moved. If the fracture involves the base of the thumb or the proximal phalanx, it is recommended to wait until the fracture has healed before flexion and extension activities can be performed. Fractures of the thumb should take about 6 weeks to heal, and if the fracture does not involve the stopping point of the tendon, the joint can be functionally trained in 3-4 weeks, but it is not possible to work or to hold heavy objects. If the fracture involves the bone affected by the flexor and extensor tendons along the way, it is necessary to wait until the fracture has completely healed, and then carry out the corresponding flexion and extension activities, the time is about 6 weeks.
