Welcome to the forum.
Some injuries of the wrist can severely impact the ligamentous structures and lead to injury
of these structures. This would impair the grip strength which is again aggravated by the presence of edema or swelling in the hand. The situation becomes even more complicated if there is injury to the tendons in addition. Also, necessary physiotherapy
has to be instituted by a hand therapist as soon as possible. With appropriate physiotherapy you would regain your strength slowly over weeks.
I hope this is helpful to you.
