主要发生于长管状骨干骺端部的巨细胞瘤,虽然组织学上是良性肿瘤,但采用通常的搔爬、骨移植术治疗时,局部复发率高达50%,且由于多数肿瘤浸润达关节软骨,所以有时不得不进行使关节功能残废的手术。最近,外科用超声波吸引装置(CUSA)已用于肝肿瘤、脊髓肿瘤的切除。这种装置是通过尖端喷嘴的震动产生超声波,通过超声波打碎瘤组织,同时进行冲洗、吸引。其对于骨作用十分锋利。即使对肿瘤广泛浸润软骨的病例,也可用这种 CUSA 行彻底搔爬,再通过软骨下支柱骨移植,防止复发和保存关节功能。使用 CUSA 进行搔爬的病例共12例,其中巨细胞
Occurred mainly in the long tubular metaphyseal bone giant cell tumor, although histologically benign tumors, but the usual scratching, bone graft treatment, the local recurrence rate as high as 50%, and because most of the tumor invasion of articular cartilage , So sometimes have to make the operation of handicapped joint function. Recently, surgical ultrasound aspiration device (CUSA) has been used for resection of liver tumors and spinal tumors. This device is through the tip of the nozzle vibration ultrasonic waves, broken by ultrasound tumor tissue, flushing at the same time, to attract. Its effect on the bone is very sharp. Even in cases of widespread infiltration of cartilage tumors, this CUSA line can be used to thoroughly scratch and then through the subchondral bone graft to prevent recurrence and preserve joint function. A total of 12 cases were screened using CUSA, including giant cells
