Pelvic ring reconstruction with segmental spinal instrumentation after complete type I pelvic resection. Issue 8 (25th August 2020) - Tepper, Sarah C.
Abstract: Background and Objectives: Internal hemipelvectomy is a complex procedure used to treat malignancy that involves the pelvis. Reconstruction of the pelvis after type I or type I/IV resection remains controversial due to high complication rates and debatable functional benefit. Modern reconstruction options may provide a rapid, intuitive, and reliable way to reconstitute the pelvic ring. Methods: This is a retrospective case series of four patients who underwent a novel reconstruction method involving computer navigation and segmental spinal instrumentation applied to the pelvis after type I or type I/IV pelvic resection for malignancy between 2015 and 2020. Results: Time to ambulation postoperatively ranged from 1 to 7 days, and median length of hospital stay was 8.5 (7.5, 10.5) days. Complications included wound necrosis in two patients that did not require reoperation and wound infection in one patient that required irrigation and debridement. There was no radiographic evidence of hardware loosening or failure on follow‐up. Three patients remain alive and two remain disease‐free. At most recent follow‐up, all patients were able to ambulate and perform activities of daily living. Conclusions: The technique for pelvic reconstruction described allows for rapid fixation intraoperatively with few complications and satisfactory functional results in this limited series.
