More info needed: Hand fractures that heal in a less than optimal position can result in poor function, pain and arthritis.

If you are not sure what you doctor wants to do and why, ask more questions. Also consider getting a second opinion from a board certified hand surgeon.

Most likely: Sounds like you have a fracture that hasn't healed properly. In such a case it can be fixed by re-cutting the bone, positioning it correctly and inserting new bone if needed. The hip area is the best place to get the new bone.

It depends: Limited motion after hand fracture can result from joint contracture (stiffness), tendon adhesions, or the position in which the fracture healed. Even if if the bone healed in a bad position, function may be restored by hand therapy alone. If surgery is necessary to correct the bone alignment (osteotomy), bone graft from the wrist, elbow or hip can be used to facilitate healing. Synthetic also.
