Multiple treatment modalities exist for unicameral bone cysts (UBC), including steroid injection, autologous marrow mechanical decompression, intramedullary fixation, curettage, and grafting. All have their own potential limitations such as high recurrence rates, cyst persistence, need multiple procedures, prolonged immobilization. A minimally invasive regimen consisting of injection a calcium sulfate-calcium phosphate (CaSO4-CaPO4) composite has been utilized at our institution in an attempt to obtain optimal results the UBCs pediatric population.We retrospectively evaluated 16 patients with pathologically confirmed UBC who were treated between April 2006 August 2010 single institution. The average age time surgical intervention was 9.4 years (range, 3 y). Average follow-up months 6 36 mo). Radiographic healing, clinical outcomes, complications evaluated.Final radiographs demonstrated healing 93.7% (15 16) after procedure. Complete observed 14 partially healed defect 1 patients. One patient had persistent but did not wish receive further treatment. returned full activities sports on 3.1 mo) asymptomatic most recent follow-up. No postoperative complications, refracture, observed.Curettage, population demonstrates encouraging low rates compared conventional methods.Case series, Level Evidence IV.
