All of the following are principles of tendon transfers except: (A) There should be no contracture at the joint, (B) The line of pull must be straight, (C) One tendon must do one function only, (D) A muscle power less than 3 can also be used
Answer is B. Answer- B. The line of pull must be straightAdequate strengthThe tendon chosen as a donor for transfer must be strong enough to perform its new function in its altered position.Selecting an appropriate motor is impoant because a muscle will lose one grade of strength following transfer. Do not transfer muscle that has been reinnervated or muscle that was paralyzed and has returned to function.
