H emicorporectomy (also known as translumbar amputation, halfectomy) is an operation of amputation of the pelvis and lower extremities by disarticulation through the lumbar spine, as well as creation of conduits for diversion of urinary and fecal tracts. 1 Originally, hemicorporectomy was performed in cases with locally aggressive cancers confined to the pelvis. However, it was also claimed to be beneficial in patients with severe trauma to the pelvis and lower extremities, 2 vascular malformations, acute aortic occlusion, recurrent perianal and scrotal fistulas and terminal pelvic osteomyelitis (this term represents pelvic osteomyelitis with chronic decubitus ulcers which is refractory to treatment with antibiotics and standard surgical treatments). 1,3,4 Hemicorporectomy is not a common operation due to its invasive procedure. However, it can be a life-saving operation with good co-operation among the multi-disciplinary team.The life-threatening intra-operative complication was hypotension, while post-operative wound complications were experienced by all cases. The term 'wound complications' refers to superficial wound dehiscence, delayed wound healing, and osteomyelitis of distal lumbar spine. Genitourinary complications (including recurrent urinary tract infection, pyelonephritis, renal calculi and urosepsis) are also found in many cases. 1 This case report illustrates two cases of patients suffering from malignancy in pelvis and lower extremities. The first case was diagnosed high grade osteosarcoma at sacrum, while the other was recurrent giant cell tumor at left proximal femur.
Case reportTwo cases are described in this study. The first case is an 18-year-old female with high grade osteosarcoma at sacrum presented with chronic pelvic pain unalleviated by analgesic drugs. Pathologic examination showed high grade osteosarcoma stage IIB at sacrum. After receiving neoadjuvant chemotherapy, the tumor was not decreased in size and still did not present metastasis. MRI revealed that the tumor had invaded the entire sacrum and all sacral nerve roots with severe soft tissue extension and bony margin surrounding the 5 th lumbar vertebra, shown in Figure 1.
AbstractA case report of two successful cases who underwent hemicorporectomy, previously known as translumbar amputation. The first patient was diagnosed high grade osteosarcoma at sacrum. The other was recurrent giant cell tumor at left proximal femur.
