放射性股骨颈骨折已有较多报道,而放射性肋骨、锁骨骨折报道较少。在高能射线应用后放射野的设置已改进,避免了直接照射股骨颈,因此放射性股骨颈骨折已很少发生。但肋骨、锁骨在放疗时不能避免直按照射,随着肺癌治疗后生存期的延长,乳癌应用放疗增多,预期肋骨、锁骨的放射性骨折将会增多。放射性骨折可能误诊为肿瘤侵犯而给以不必要的放疗使放射损伤更为加重,故应鉴 Radioactive femoral neck fractures have been reported in many cases, and radioactive ribs and clavicle fractures are rarely reported. The setting of the radiation field after the application of high-energy radiation has been improved to avoid the direct irradiation of the femoral neck, so that radioactive femoral neck fractures have rarely occurred. However, ribs and clavicle can not avoid direct radiation during radiotherapy. With the prolongation of survival after lung cancer treatment, the use of radiotherapy for breast cancer increases, and it is expected that radiological fractures of ribs and clavicle will increase. Radiological fractures may be misdiagnosed as tumor invasion and given unnecessary radiotherapy to aggravate radiation damage.
