Unwinding of a 4.5 mm partially threaded cannulated screw in an elderly patient: A case report
Author(s): Michael Booth MD and George Bal MD
Abstract: Case: An elderly patient sustained a base of the coracoid fracture with superior clavicle migration requiring open reduction internal fixation. When inserting our 4.5 mm partially threaded cannulated screw, it began to unravel revealing an underlying screw defect. Conclusion: There may be a biomechanical defect with the partially threaded cannulated screws which may require pre-drilling prior to insertion.
