Unexpected radiographic lucency following grafting of XXXX with @entity77 / @entity9039 bone substitute.

OBJECTIVE: To report the development of unexpected radiographic lucency (URL) corresponding to the use of a commercially available @entity77 / @entity9039 composite used to treat @entity75 . MATERIALS AND METHODS: This is a retrospective comparative study of @entity1 with and without URL after treatment with curettage and grafting with @entity77 / @entity9039 . The charts of 87 @entity1 meeting the inclusion criteria were reviewed for demographic, clinical, and radiographic data. The group with URL was compared to those with more typical patterns of graft incorporation. RESULTS: Thirteen of 87 cases (15  %) showed URL. There was no difference with respect to the pathologic subtype, anatomic location, or specific bone for the presence of URL. Of @entity1 with URL, one (7.7  %) required reoperation and regrafting, whereas among @entity1 without URL, five (6.7  %) had clinical complications, with one requiring reoperation and regrafting, and one requiring radiofrequency ablation. CONCLUSIONS: The majority of @entity1 treated with @entity77 / @entity9039 cementing after curettage of low-grade @entity79 go on to uneventful healing in our series. In a minority of @entity1 , URL occurs in lieu of the more typical pattern of centripetal incorporation. However, there is no increase in complications associated with URL. Based on these findings, @entity1 should be informed of the possibility of this risk, although there appears to be little risk of clinically relevant adverse consequences. Physicians should be aware of this complication in order to avoid mistaking it for recurrence of the @entity75 .
