Experimental Evaluation Of The Developmental Mechanism Underlying Fractures At The Adjacent Segment.
Compression fractures at adjacent mobile segments have been reported as adjacent segment disease under trauma in several studies. In this study, the occurrence of fractures at the adjacent segment was evaluated experimentally under trauma. ⋯ The dynamic system with a polyetheretherketone rod can better preserve both adjacent and fixed segments. However, because of the cantilever beam effect, the semirigid system exhibits a great disadvantage.

Case Reports
Primary intracranial sarcoma presenting as chronic subdural fluid collections in a child - report of a case.
Chronic subdural hematoma in the pediatric population often results from trauma. Asymptomatic and benign-appearing subdural collections are generally managed conservatively without operative intervention. Primary intracranial sarcomas are uncommon entities. Diagnosis of sarcoma can be difficult because these lesions often manifest as apparent hematoma. ⋯ Early contrasted magnetic resonance imaging should be obtained in patients with subdural fluid collections that appear asymmetric or do not resolve in the expected time course, despite having a normal neurologic examination result. Negative cytologic assessment does not exclude sarcoma diagnosis.

The role of the overall structural feature of facet joint in the development of lumbar disc herniation (LDH) is unclear. The present study aimed to investigate the role of irregular alteration of facet orientation (IAFO) in low lumbar segments in the pathology of LDH in adolescents. ⋯ The findings of this study suggest that the IAFO in the lumbar spine was associated with lumbar disc herniation in adolescents.

Case Reports
Transorbital Penetrating Intracranial Injury with an Umbrella Wire causing Cavernous ICA Injury and Thrombosis.
Transorbital penetrating intracranial injuries, though rare, can have serious consequences. Intracranial penetration can be present even if orbital trauma is trivial. ⋯ Trivial orbital injuries can be associated with significant intracranial injury in a neurologically intact patient. This case emphasizes the potentially injury-prone opening mechanism of conventional umbrellas. A high index of suspicion is important while evaluating such patients.

Symptomatic extensive spinal extradural meningeal cyst (SEMC) developing after traumatic brachial plexus injury (TBPI) is rare. We discuss the mechanism of extensive SEMC development, surgical strategies, and preventive measures against SEMC after TBPI. ⋯ For patients with TBPI, it is necessary to prevent greater CSF pressure and to perform long-term follow-up MRI after injury.
