This book serves as a practical text on the subject of hand surgery that covers all of the practical mechanical principles in a nonthreatening way. The book covers all of the basic elements of the forces that result in movement of the hand, and all the forces that hinder its movement. The authors quantify those elements in manner in which surgeons and therapists can judge their own measure of success or failure as they try to repair and restore movement to damaged hands.* This newest edition seeks to improve upon this source of information by increasing the amount of material covering applications to trauma, arthritis, Dupuytren's disease, spasticity, and overuse syndromes. * New sections also cover extensor mechanisms, wrist, forearm, and outcome studies.
