Introduction/Cases. Two pediatric patients presenting with benign bone tumors of the distal femur at the level of the suprapatellar fat pad developed late onset recurrent knee hemarthrosis following surgical treatment of the lesions. A sinus tract from the intramedullary bone to the knee capsule was discovered in both patients during surgical exploration. Resection of the sinus tract and full closure of the knee capsule resulted in no further recurrence. Conclusion. Postoperative knee effusions in patients following resection near the distal femur could represent hemarthrosis that require additional workup and treatment. Resection of the sinus tract successfully treats the hemarthrosis.

Introduction The chondromas are a cartilaginous proliferation of mature appearance and moderate size, reason why these tumors are regarded more like hamartomas than real benign tumor. Chondromas represent 10 to 12 % of benign bone tumors. Any bone of an enchondral ossification may be involved. Several bones can be involved, and the disease is called “chondromatosis”. In the review we describe clinical and radiological findings of this pathology as well as indications for reconstructive surgery. Material and methods The review is dedicated to isolated chondromas, periosteal and extraskeletal chondromas, chondromatosis. Results The aspects of epidemiology, clinical presentation, radiology, MRI, prognosis, indications and methods of surgical treatment have been described in the article for each types of chondroma and enchondromatosis. Conclusion Chondromas are benign bone tumors which may be responsible of pathologic fractures. Their surgical treatment consists in curettage and bone grafting or bone-cement filling with or without osteosynthesis. Multiple enchondromatosis should be considered as an osteochondrodysplasia. Its treatment is not the treatment of the multiple chondromas themselves, but of the bone deformities and length discrepancy induced by the disorder. The transformation of some tumors in chondrosarcomas in adolescence or adulthood needs a strict follow up of these patients.

Benign bone tumors in the pediatric population can have varied clinical presentations ranging from asymptomatic to nonspecific pain, swelling, or pathological fracture. A systemic imaging approach should be utilized to evaluate for focal bone abnormalities. Radiologists must be aware of salient imaging features of pediatric benign bone tumors, as it helps to guide clinicians for further management and help decreasing patient anxiety and unnecessary medical intervention.

Objective. To determine the interobserver and intraobserver reliabilities of the Enneking Classification system in staging benign bone tumors. Methods. Photographs of traditional plain radiographs of 65 histologically benign tumors from the PGH Department of Orthopedics Tumor Registry were used in the study. Nine Orthopedic surgeons (three consultants, one fellow, and five senior residents) staged the tumors using the Enneking Classification based on radiographic tumor-host margins. The photographs were sent to the surgeons twice (batch 1 and 2), three months apart, for staging. The Fleiss and Cohen kappa statistics were used to determine interobserver and intraobserver reliabilities, respectively. This is a pilot study. Results. There was only fair interobserver reliability of the Enneking Classification staging with Fleiss kappa of 0.38 and 0.26 for batches 1 and 2, respectively. Also, there was only moderate intraobserver reliability (Cohen kappa 0.48) for the staging. Moreover, there was also a relatively low intraobserver percent agreement (67%) among raters. In both reliabilities, the consultants/fellow group consistently showed better interobserver and intraobserver reliabilities compared to the residents. Conclusion. The Enneking Classification in staging benign bone tumors had relatively low interobserver and intraobserver reliabilities. There was also a tendency of experienced orthopedic tumor consultants and senior residents to stage the same radiograph differently upon repeat testing.
