Abstract:
Objective:To investigate the clinical effectiveness of tumor lesion curettage and allogeneic bone grafting via the fovea of femoral head through the surgical hip dislocation approach in children and adolescents with femoral head chondroblastoma (FHCB).Methods:Case series study.The clinical data of 7 FHCB patients [3 males and 4 females with a mean age of 13.7 years (11-19 years)] treated at the Department of Pediatric Orthopedics, Zhengzhou Orthopedic Hospital from January 2016 to March 2023 were retrospectively analyzed.All patients underwent lesion curettage and allogeneic bone grafting via the fovea of femoral head through the surgical hip dislocation approach.The healing, local recurrence and complications were assessed via clinical and radiological tests.Functional outcomes were evaluated using the Musculoskeletal Tumour Society (MSTS) scoring system.A paired t-test was used to compare the MSTS scores before the operation and at the final follow-up. Results:All patients were followed up for 30 months on average (18-48 months).The average healing time for bone grafting was 4.9 (3-8) months.Local recurrence and serious postoperative complications such as avascular necrosis of femoral head, secondary osteoarthritis, ectopic ossification and nonunion of greater trochanter osteotomy end were not observed in all patients up to the last follow-up.The average MSTS score at the last follow-up was (29.14±0.45) points.Conclusions:Curettage and bone grafting via the fovea of femoral head through the surgical hip dislocation approach is effective and safe in the treatment of FHCB in children and adolescents.This method can maintain the integrity of the articular surface and growth plate, and also preserve the blood supply of the femoral head and the normal function of the hip joint, with satisfactory short-term effects.
