When pathological fractures occur, the local thin bone cortex makes internal fixation very difficult. If clinicians are worried that the disease is too large or children have too much activity and lead to fracture, it is usually preventive aspiration and injection of methylprednisolone or surgical intervention. During this period, it is often necessary to restrict movement in order to avoid pathological fracture. All SBCs will heal by themselves, but they will not subside until the bone is mature. However, when the lesion is located in the non-bearing part (humerus) and the risk of pathological fracture is uncertain, there are many disputes about the timing of treatment ( 3, 4). Due to the high risk of pathological fractures and the persistent symptoms of pain and lameness, surgery is currently the first choice of clinical treatment for SBCs with lesions located in the weight-bearing part (femoral neck). Clinically, SBCs rarely achieves complete cure, except with wide excision which has a recurrence rate of 30%. The main indication for the treatment of SBCs is the risk of pathological fractures ( 1, 2). In approximately 80% of cases, the lesions occur in the proximal humerus and the proximal femur. Simple bone cysts (SBCs) are the most common osteolytic lesions in children, which usually occur in the long bones of the extremities.

The lesion is located at TEAL, so we should be alert to the risk of pathological fracture. Ĭonclusions: SBCs of humerus in children is often accompanied by pathological fracture. The results demonstrated that the TEAL was an independent risk factor for fractures. Results: Binary logistic regression analysis was performed on the age, gender, and cyst index, and whether the lesion was located in the TEAL. Perform binary logistic regression analysis. The presence of the pectoralis major and the link to the tendon insertion site of ectopectoralis and anconeus lateralis (TEAL) of the lesion were also examined. The relationship between pathological fractures and the children’s age, gender, and cyst index was analyzed. Patients were divided into a fracture group (35 cases) and a non-fracture group (10 cases). Methods: The medical records and plain films of patients with SBCs from January 2014 to December 2021 were retrospectively analyzed. The purpose of this study is to retrospectively analyze the risk factors of pathological fracture of simple bone cyst of humerus in children. Therefore, it is necessary to find a basic and simple imaging evaluation index in clinic. MRI can clearly show the cyst boundary, the appointment cycle is long, and children need to be examined under sedation, which cannot be judged by clinicians in time. Cyst index is a classic index to evaluate the risk of pathological fracture, but the reliability of this index is reduced due to the deviation of cyst area in the frontal and lateral position and the subjectivity of the determination of cyst area. Background: Simple bone cysts (SBCs) are common osteolytic lesions in children, which often lead to pathological fractures of the non-weight-bearing bone (humerus) in patients.
