[1] Indications for external hemipelvectomy include neoplastic extension into the sciatic nerve, where loss of function of the lower extremity is anticipated.
[1] As with any surgical procedure, risks include infection, blood loss, damage to surrounding structures, cardiac/pulmonary complications, and adverse reactions to anesthesia.
[1] Such techniques ensure that adequate resection margins are obtained at the time of surgery to minimize tumor recurrence.
[1][3] Resection of pelvic bone typically requires subsequent reconstruction to ensure stability of the hip joint, particularly in internal hemipelvectomy.
[1][4] Arthrodesis is a technique that can be used in internal hemipelvectomy to fix the proximal femur to a segment of pelvic bone for the purposes of stabilizing the lower extremity.
