Abstract

Simple bone cyst is a pseudotumor lesion of the bone, common in children and often appears in the metaphysis of the proximal humerus and femur. Although benign, simple bone cyst in the femoral neck-trochanter area of children often cause complications of pathological fractures, affecting the child's motor function. In addition, because this is a load-bearing area, lesion in this area, whether broken or not pathologically broken, requires treatment intervention to prevent complications that cause disability for the patient. We performed a retrospective study describing clinical characteristics, treatment methods and treatment outcomes in pediatric patients under 16 years old, from 2016 to 2023.

Result: 16 patients, including 10 men and 6 women, average age 11.6 years, average follow-up time 52.1 months. There were 11 patients hospitalized for pathological fractures, 3 patients due to accidental discovery and 2 patients due to pain symptoms. Regarding treatment: (1) Group of 5 patients without pathological fractures, of which 4 had curettage + bone graft + hip-spica cast, 1 had only biopsy + hip-spica cast, all had good bone healing results; (2) Group of 11 patients with pathological fractures, of which 5 patients were in a hip-spica cast for 1-2 months, waiting for the broken bone to heal and then curettage + bone grafting for fair bone healing results; 4 patients of curettage + bone grafting + immediate fracture fixation resulted in 2 fair and 2 good bone healing results; 1 patient of continuous decompression and 1 patient of conservative hip-spica cast both resulted in good bone healing.

Conclusion: Although easy to heal, simple bone cyst in the femoral neck-trochanter area in children require appropriate treatment, especially in cases of pathological fractures, to achieve good bone healing results.
