Function
The solitary function of this bone is to increase torque (ability to overcome resistance) and aid rotation of the wrist and hand. Generally, while twisting and turning, the thing falls on the side. The pisiform bone creates torsion in the wrist and prevents the complete turning of the hand during twist and turn movements.
Disease/ Injury/ Fracture
This bone is fractured very rarely. Bone gets fractured along with other hand injuries or other bone fractures in the region of hand and wrist. Fracture of this bone may damage the nerve in the area resulting in reduced grip strength.
