The computed tomographic (CT) examinations of 17 patients undergoing evaluation for limb-sparing treatment of osteosarcoma were evaluated. In all cases information from CT directly affected the operative approach. The CT findings that helped in planning the operative approach included determination of intramedullary extent and evidence of "skip" metastases, direct extension into an adjacent joint, and neurovascular compromise. Performing CT of the affected bone at 1-cm intervals from the joint above through the joint below and including the contralateral side in the field of view allow precise localization of findings that can direct the operative approach. Close and contiguous scanning intervals allow identification of small intramedullary "skip" metastases that affect the resection margins.
对17例接受骨肉瘤保肢治疗评估的患者的计算机断层扫描（CT）检查进行了评估。在所有病例中，CT提供的信息直接影响手术入路。有助于规划手术入路的CT表现包括确定髓内范围及“跳跃”转移灶的证据、直接延伸至相邻关节以及神经血管受压情况。从上方关节至下方关节以1厘米的间隔对患骨进行CT扫描，并在视野中包括对侧，这样可以精确地定位能够指导手术入路的发现。紧密相邻的扫描间隔能够识别影响切除边缘的小的髓内“跳跃”转移灶。
