我们报告了我们在7例股骨远端骨肉瘤患者中使用非侵入性股骨远端可膨胀内假体的早期经验。手术时患者的平均年龄为12.1岁（9 - 15岁）。假体在门诊诊所以适当的时间间隔延长，没有麻醉，使用电磁感应原理。使用肌肉骨骼肿瘤协会评分系统对患者进行功能评估。平均随访20.2个月（14 ~ 30）。假体平均延长25 mm（4.25 ~ 55 mm），平均膝关节屈曲度保持110 °（100 ° ~ 120 °）。平均肌肉骨骼肿瘤协会评分为68%（11 - 29）。2例患者出现并发症; 1例膝关节屈曲畸形25度，随后克服，1例死于播散性疾病。使用该设备治疗的患者的早期结果令人鼓舞。该植入物避免了多次外科手术，全身麻醉，并有助于保持腿长的平等。
We report our early experience with the use of a non-invasive distal femoral expandable endoprosthesis in seven skeletally immature patients with osteosarcoma of the distal femur. The patients had a mean age of 12.1 years (9 to 15) at the time of surgery. The prosthesis was lengthened at appropriate intervals in outpatient clinics, without anaesthesia, using the principle of electromagnetic induction. The patients were functionally evaluated using the Musculoskeletal Tumour Society scoring system. The mean follow-up was 20.2 months (14 to 30). The prostheses were lengthened by a mean of 25 mm (4.25 to 55) and maintained a mean knee flexion of 110 degrees (100 degrees to 120 degrees). The mean Musculoskeletal Tumour Society score was 68% (11 to 29). Complications developed in two patients; one developed a flexion deformity of 25 degrees at the knee joint, which was subsequently overcome and one died of disseminated disease. The early results from patients treated with this device have been encouraging. The implant avoids multiple surgical procedures, general anaesthesia and assists in maintaining leg-length equality.
