Reconstruction using a constrained-type hip tumor prosthesis after resection of malignant periacetabular tumors: A study by the Japanese Musculoskeletal Oncology Group (JMOG).

We analyzed the outcome of 80 patients with periacetabular tumors undergoing C-THA reconstruction. The rates of postoperative complication were still high, but comparable to those in previous studies. Our results suggest wound management using a RAM flap is useful for reducing wound complications.
