The Surgical Technique for Hindquarter Amputation:A Report of 19 Cases

Abstract

The surgical technique for hindquarter amputation is described in a step-by-step manner. Since 1955 we have performed 19 such operations for eradication of malignant bone and soft tissue tumors in the pelvic, hip and upper thigh regions. Three hindquarter amputations were performed for local recurrence following initial wide excision. The overall 5-year survival rate for our 19 patients was 42.1 per cent. Malignant soft tissue tumors appear to have a much better 5-year survival rate than malignant bone tumors (60 per cent vs. 22.2 percent). We feel that surgery is still the treatment of choice. However, in the presence of proper indications, chemotherapy and radiotherapy should be added to surgery in order to prolong survival time and save lives.

Left Hindquarter Amputation due to High-Grade Pleomorphic Sarcoma of the Groin: A Case Report

“…Occasionally, hindquarter amputation has been employed in the treatment of severe trauma, metastases, and infection. One of which is soft tissue sarcomas of the groin [2,5]. examination, the lump was 30 x 30 x 30 cm (Figure 1B).…”

“…To improve patients' long-term survival rates, adjuvant chemotherapy is now routinely employed in treating certain malignant tumors, such as osteogenic sarcoma, Ewing's sarcoma, embryonal rhabdomyosarcoma, etc. Furthermore, in addition to surgery, radiotherapy, and chemotherapy; it's believed that immunotherapy effectiveness has been unequivocally proven [5,7,13].…”

“…Due to the extremely mutilating nature of this operation, it is primarily used for the eradication of malignant primary soft tissue and bone tumors of the pelvis, hip, and upper thigh regions [5]. This technique is usually performed for malignant tumors located in the proximal higher near the level of the inguinal ligament or in the iliac fossa, or tumors infiltrating the wall of the lesser pelvis that are so extensive in terms of soft tissue and osseous involvement that they cannot be conservatively removed completely with preservation of the extremity.…”
