After performing laparoscopic surgery, a 30-year-old nurse claimed that his hand extensor tendon ruptured while he was holding an endoscopic camera during the surgery. The injury was allegedly caused by a forceful grasp from a surgeon over 60 years old who suffered from carpal tunnel syndrome. The nurse was involved in a vehicle collision one week prior to the surgery, during which the air bags were deployed.
The plaintiff's mechanical engineering expert involved in the case opined the injury occurred from a localized force through a soft fiber optic cable passing through the dorsal side of the nurse's hand. The plaintiff's medical expert (hand surgeon) opined that the fiber optic cable had nothing to do with how the extensor tendon ruptured, but that the injury mechanism is possible, and compared it to a rugger jersey finger injury during flag football and to a bicep rupture during flexion.
