Surgical treatment options for aggressive XXXX in the mobile spine.

@entity5 @entity1 @entity13626
PURPOSE: @entity13626 ( @entity13626 ) is a benign bone @entity5 with considerable recurrence potential. Resection is the mainstay for the treatment of Enneking stage 3 (st. 3) @entity13626 . This retrospective study aimed to verify the appropriate surgical strategy for st. 3 lesions in the mobile spine. METHODS: 19 cases of st. 3 @entity13626 was diagnosed between 2001 and 2011. Clinical, radiological, surgical, and follow-up data were analyzed. This series included 14 @entity1 and 5 @entity1 and the mean age at diagnosis was 30.4  years. The lesions were located in the cervical spine in ten cases, in the thoracic spine in eight, and in the lumbar spine in one. Fourteen @entity1 were surgically treated for the first time (intact cases), and five were referred to us after previous unsuccessful treatments (non-intact cases). RESULTS: Before 2008, 11 @entity1 underwent curettage followed by radiotherapy, including 5 non-intact cases and 6 intact cases. @entity5 recurrence was observed in all five non-intact cases and four of the six intact cases. After 2008, eight intact @entity1 underwent intralesional vertebrectomy, including six who underwent piecemeal total vertebrectomy and two who underwent intralesional en bloc vertebrectomy. All  the eight @entity1  had  embolization  before  surgery. 18 @entity1 had an average 67.3  months (range 36-148  months) of follow-up. Recurrence was not observed in any of these eight cases with intralesional vertebrectomy. CONCLUSION: Intralesional total vertebrectomy might be an appropriate choice for intact st. 3 @entity13626 spine lesions. More cases with longer follow-up periods should be recruited in the future to better understand the treatment options available for this disease.
