Fusion success with rhBMP-2 and autograft in titanium or PEEK corpectomy devices was evaluated in a sheep lumbar corpectomy model. The 6 treatment groups included titanium mesh or PEEK corpectomy devices filled with rhBMP-2 on a compression-resistant matrix (CRM) carrier; rhBMP-2 in a morselized absorbable collagen sponge (ACS) carrier combined with resorbable ceramic granules; and autograft. ⋯ Both of the rhBMP-2 formulations have the potential to effect bony fusion and vertebral reconstruction within the corpectomy devices.

Case report. ⋯ Primary epidural Ewing sarcoma is extremely rare. The detection of the EWSR1 gene rearrangement can help to diagnose these tumors. The decision on how to treat these patients is difficult and can hardly be based on data from the current literature because of the small number of patients. The laminoplasty procedure can be safely performed in the setting of sarcoma of the epidural space.

Modified-Delphi expert consensus method. ⋯ Through a consensus-building approach, the study authors have developed a competence-based curriculum set of learning objectives anticipated to be of educational value to spine surgery fellowship educators and trainees. To our knowledge, this is one of the first nationally based efforts of its kind that is also anticipated to be of interest by international colleagues.
