Spinal transpedicular screw fixation is widely performed. Broken pedicle screw rates range from 3%-7.1%. Several techniques have been described for extraction of broken pedicle screws. However, most of these techniques require special instruments. We describe a simple, modified technique for management of broken pedicle screws without extraction. No special instruments or drilling in an adjacent pedicle are required. ⋯ We describe a simple, modified technique for management of broken pedicle screws without extraction. This technique is recommended in patients who require insertion of a new screw.

Previous studies have implicated traumatic brain injury (TBI) as a risk factor for Parkinson disease (PD). However, the incidence risk of new-onset TBI among patients with PD is not well established. This study investigated the contribution of PD to new-onset TBI associations. ⋯ This study shows that patients with PD have a high risk of TBI, and the major cause of TBI in patients with PD is fall.
