Information was received based on review of a journal article titled, "elastic intramedullary nailing and dbm-bone marrow injection for the treatment of simple bone cysts" which aimed to describe the technique and present the results of demineralized bone matrix (dbm), and autologous bone marrow injection in addition to intramedullary cannulation and stabilization for the treatment of large and active simple bone cysts using the win flexible nails manufactured at (b)(4).The study consisted of 9 patients with large active long bone cysts, 6 patients with proximal humerus cysts and 3 with proximal femur cysts.All patients were treated with thin trocar used to perforate bone cortex and aspirate cyst.Bone marrow/dbm mixture was injected into the cyst.Six weeks post op, all patients were pain free and had full range of motion.The only complication was irritation at nail entry site.The conclusion was elastic intramedullary nailing has the two-fold benefits of continuous cyst decompression, and early immediate stability to the involved bone segment, which permits early mobilization and return to the normal activities of the pre-teen patients.
