The ulcerated recurrent clear cell sarcoma of the forearm with bony invasion of the radius needed an uncontaminated resection and control of infection. A mold was printed based on CT-reconstructed 3D models of the patient's anatomy to create an antibiotic-loaded cement spacer as endoprosthetic replacement used in combination with soft-tissue reconstruction and systemic antibiotics.
This then undescribed novel technique allowed for fast local recovery of the patient's hand function and return to work. In selected cases, such an anatomically formed spacer may be preferred for faster functional recovery and longer intervals before definitive reconstruction is possible.
前臂溃疡复发性透明细胞肉瘤伴桡骨骨侵袭，需要进行无污染的切除和感染控制。根据患者解剖结构的 CT 重建 3D 模型打印出一个模具，以创建载抗生素的水泥间隔物作为假体替代物，与软组织重建和全身抗生素联合使用。
这种新颖的技术可以使患者手部功能快速恢复，并尽快返回工作岗位。在某些特定情况下，这种解剖成型的间隔物可能更有助于更快地恢复功能，并且在可行的确定性重建之前可以有更长的间隔时间。
