ABSTRACT
Introduction: Simple bone cyst or unicameral bone cysts are benign osteolytic lesions seen in metadiaphysis of long bones in growing children. Various treatment modalities with variable outcomes has been described in the literature. Case report show novel surgical technique of minimally invasive method of treatment with better outcome. Case study: A 14-year-old boy diagnosed as active simple bone cyst proximal humerus with pathological fracture. Patient was treated by minimally invasive percutaneous curettage with curved titanium elastic nail (TENS) and allogenic bone grafting mixed with bone marrow under image intensifier guidance. Results: Pathological fracture was healed and allograft filled in the cavity well taken-up. Patient achieved full range of motion with successful outcome. Conclusion: Minimally invasive percutaneous method using elastic intramedullary nail give benefit of curettage cyst decompression and stabilization of fracture. Allogenic bone graft fills the cavity and healing of lesion occurs by osteointegration. This method may be considered with advantage of minimally invasive technique in treatment of benign cystic lesions of bone. Level of evidence: Therapeutic level IV.
