A surgical approach for treating patients with resected, recurrent, posterior pelvic visceral tumors involving the sacrum is detailed. Of 11 patients, 9 had rectal cancers, 1 had chordoma, and 1 had cancer of the cervix. Five total pelvic exenterations and five posterior exenterations were performed en bloc with involved sacrum. One patient had a sacral resection only. Surgical mortality was 9%, and the average hospital stay was 1 month. Mean disease-free survival was 1 year, and mean survival was 3 years. Absolute cure rate was 18% with a complete 5-year follow-up. This experience confirms the value of this procedure in selected patients.

Background: Open pelvic fractures are rare but represent a serious clinical problem with high mortality rates. Acute mortality is often associated with hemorrhage, whereas delayed mortality is most often associated with sepsis and multiple organ failure. We report a case of Wang's classification of type II open pelvic ring fracture with hemorrhagic shock and septic shock from gas gangrene.

Objective: Determining the optimal osteotomy length for patients with unilateral Crowe-IV developmental dysplasia of the hip undergoing subtrochanteric osteotomy remains challenging due to the significant variability in pelvic and spinal alignment. Incorrect osteotomy length, compounded by pelvic or spinal tilt, can adversely affect postoperative gait and long-term outcomes. Therefore, this study could introduce a method to calculate the osteotomy length for patients with unilateral Crowe-IV developmental dysplasia of the hip, correcting spinal and pelvic tilt, and improving patient gait.

Background: Electromagnetic navigation (EMN) is an advanced technology increasingly utilized in orthopedic surgery for its ability to provide real-time intraoperative guidance. Its application in spinal surgery is evolving rapidly, particularly for complex cases like tumor lesions. Spinal osteoblastomas, characterized by their benign nature, primarily affect the posterior elements of the spine.
