Injection of demineralized bone matrix with bone marrow concentrate improves healing in unicameral bone cyst

Abstract

Background: Unicameral bone cysts are benign lesions that usually spontaneously regress with skeletal maturity; however, the high risk of pathologic fractures often justifies treatment that could reinforce a weakened bone cortex. Various treatments have been proposed but there is no consensus regarding the best procedure. Questions/purposes: We compared the healing rates and failures of two methods of cure based on multiple injections of corticosteroid or a single injection of demineralized bone matrix (DBM) in association with bone marrow concentrate (BMC). Methods: We retrospectively reviewed 184 patients who had one of the two treatments for unicameral bone cysts with cortical erosion. Cl..
