Physeal Distraction During Surgical Treatment of Osteosarcoma of the Femury

Introduction First report of an actuate physeal distraction in preseaving the unvolved metaphysis in osteosarcoma patient. Case presentation We treated a 9-year-old female, Asian heritage patient with osteosaccoma of the diaphysis and metaphysis of her left femur which left an intact epiphysis and growth plate and was not suit for the Cañadell technique of physeal distraction. After neoadjuvant chemotherapy, she received tumor resection, actuate physeal distraction (1-2mm/min), the involved femur inactivation and re-implantation sequencely. 4 cycles of adjuvant chemotherapy was taken in this patient. The whole surgery lasted for about 3 hours, with a totle blood loss of less than 600 ml. The epiphysis was separated at 35 minutes.The wound healed well. During the following up of 38 months, her limb discrepency reached 10 cm with no tumor relapse or metastasis. The revised Musculoskeletal Tumor Society score increased from 8 of preoperative value to 23 postoperatively. The main problum is bone healing, limtation of knee joint function and involved limb shortage. Conclusion Physeal distraction during surgery is an alternative treatment of Cañadell technique in given patients with satisfied clinical result except for markable limb discrepancy .
