Abstract

PURPOSE: To evaluate the results of operative treatment for metaphyseal pathologic fracture of long bone in children using Locking Compression Plate (LCP).
MATERIALS AND METHODS
Six children were enrolled in this study. The locations of fracture were proximal femur in five children and distal femur in one child. Pathologic diagnosis was aneurysmal bone cyst, in three children and simple bone cyst, enchondroma, and nonossifying fibroma, in other three children. All six children were underwent curettage of bone lesion and bone grafting, then the fractures were internally fixed using LCP.
RESULTS
All fractures were united at six to ten weeks after operation. Healing of bone lesions except one case was observed. There were no mechanical complications, no loss of reduction and malunion. Also, we couldn't find any complication associated with physeal injury, such as leg length discrepancy of lower extremities.
CONCLUSION
Internal fixation of metaphyseal pathologic fracture of long bone using LCP in children is technically easy and offers secure fixation despite anatomic and biologic characteristics of this type of fracture due to biologic and biomechanical advantages of LCP.

  Fig. 1 (A) Preoperative plain radiograph of 9-year-old boy shows expansile radiolucent lesion and associated fracture in left proximal femur. (B) Immediately postoperative radiograph shows curettage and autologous fibula and calcium sulfate (osteoset®) graft for the aneurismal bone cyst and internal fixation of fracture using LCP. (C) Plain radiograph taken 14 months after surgery shows solid fracture union and healing of underlying aneurismal bone cyst.

  Fig. 2 (A) Preoperative plain radiographs of 16-year-old boy show large radiolucent cystic lesion and associated comminuted fracture in left proximal femur. (B) Immediately postoperative plain radiographs shows curettage and autologous fibular and calcium sulfate (osteoset®) graft for the simple bone cyst and internal fixation of fracture using LCP. (C) Plain radiograph taken 8 months after surgery shows healing of cystic lesion and solid union of fracture without complications.
