Osseoscopy: Direct Visualization to Assist Core Decompression and Debridement of Necrotic Bone Defects.

Free vascularized fibular grafting after core decompression and debridement of necrotic lesions is an effective surgical treatment of avascular necrosis of the femoral head. A technical challenge encountered in performing this procedure is ensuring adequate debridement of necrotic parts while preserving healthy bone. A previously described method accomplishes this indirectly using radioactive contrast media and fluoroscopy, increasing the risk of radiation exposure.

Sex disparities in postoperative outcomes after neurosurgical intervention: findings from the UMEND project.

Background: Little is known about the relationship between sex and the risk of complications after neurosurgical intervention. Improved understanding of this relationship may assist clinicians in advising patients of the risks and benefits of neurosurgical intervention and managing their patients after surgery.

Objective: To determine the independent relationship between sex and morbidity after neurosurgical intervention.
