Introduction:
Simple bone cyst (SBC) is the most common cause of pathological fracture in children. The most common sites are proximal humerus and proximal femur. There is no specific protocol in the management of pathological fractures with SBC. Treatment options include intralesional injection of steroids and bone marrow aspirate, percutaneous or open curettage of the lesion with or without bone grafting.
Case report:
We report a case of pathological fracture of distal humerus due to SBC in a 16-year-old male. The fracture was treated surgically. Open reduction was done; curettage of cyst wall followed by non-vascularized fibula strut grafting was done and fixed with bicolumnar plating. Early post-operativemobilization was started. The patient had good outcome with incorporation of graft and healing of fracture and lesion.
Conclusion:
Unstable pathological fractures due to SBC require osteosynthesis and curettage of lesion with bone grafting. Stable fractures can be managed conservatively.
