Hello and thanks for the query
of the bone take about 4-6 weeks to heal properly. Callus
formation starts after 3 weeks of injury
. In case of wrist the cast can be removed as early as after 4 weeks by reviewing the X-ray. 11 days are too short to remove the cast. You have to wait for another 2 weeks for that. A sprain
cast can be removed after 2 weeks but sometimes we have to keep it for 3 weeks also. Your doctor can explain you better as he/she knows well about your injury.
