Nontraumatic pedicle fracture is uncommon, with sparsely described cases of conservative management versus surgical treatment by open fusion or percutaneous fixation. ⋯ A trial of conservative management is typically warranted in most cases of nontraumatic pedicle fracture, but there is risk of refractory or progressive symptoms and subsequent fracture. Minimally invasive fixation is a viable surgical option that can be used in multilevel fractures.

Case Reports
A rare case of non-traumatic, multi-level, bilateral pedicle fractures of the lumbar spine in a 60-year-old patient.
We report a 60-year-old patient who sustained non-traumatic, multi-level, bilateral lumbar pedicle fractures in the setting of unilateral lumbar spondylolysis. A possible fracture mechanism is evaluated and a review of the literature is presented. Whereas contralateral pedicle fractures of lumbar vertebrae with unilateral spondylosis are well described in young athletes, there is only one case report of multi-level, bilateral pedicle fractures of the lumbar spine in a young patient who sustained a high-impact motorcycle accident. To our knowledge, this is the first report of multi-level, bilateral pedicular fractures of the lumbar spine without a history of trauma. ⋯ The presented fracture pattern has not been described to date. Because of multi-level involvement, instability requiring operative stabilisation was presumed and confirmed during surgery.

Case Reports Comparative Study
Surgical versus nonsurgical treatment of subaxial cervical pedicle fractures.
Pedicle fractures in the cervical spine are common. They may occur in isolation or in combination with other concomitant fractures. Multiple classification systems have been introduced to provide a clinical framework when approaching these types of fractures; however, these systems do not provide guidelines for optimal treatment. Data regarding decision making are limited. Conservative treatment with orthoses may result in subluxation and instability requiring further treatment. Surgery may not be required in all instances because many of these injuries may heal without surgical intervention. ⋯ This study describes and classifies unique cervical pedicle fractures and associated injuries. Our findings suggest that surgical treatment results in definitive stability for these injuries compared with conservative therapy, particularly for pedicle fractures associated with comminuted lateral mass or initially displaced fractures. However, nondisplaced vertical split pedicle fractures and isolated single line horizontal fractures may be treated nonsurgically without occurrence of further instability. A larger prospective study is required to confirm these findings.
