Abstract
To solve the distal locking difficulty arising from the bending and twisting of the intramedullary nail axis while the nail implanting in long bone fracture therapy, an image-guided computer-assisted orthopaedic surgery system was introduced. To evaluate the error distribution of the system, a special error analysis method was designed based on the character of the system structure and its geometric model. The concrete calculation and statistics of error distribution were embodied by the assistance of the Monte-Carlo method. The system performance was also evaluated in order to derive the theoretical guarantees for further optimizing the system. This error analysis method can be used for the similar systems with complicated mathematical models.
