Curved periacetabular osteotomy via a novel intermuscular approach between the sartorius and iliac muscles.

Introduction: Herein, we describe and evaluate a curved periacetabular osteotomy (CPO) via an intermuscular approach (IM-CPO) between the sartorius and iliac muscles.

Methods: Between January 2009 and January 2016, IM-CPO was performed in 17 joints (16 patients), and a traditional CPO was performed in 17 joints. The length of incision at wound closure, operative time, intraoperative blood loss, serum creatinine kinase (CK) level the day after surgery, correctional angle, walking ability assessed using the gait items of the Harris Hip Score (at 3 and 6 months after surgery), and perioperative complications were evaluated.

Computed tomography-guided resection of osteoid osteoma of the sacrum: a case report.

Introduction: Osteoid osteoma is a benign tumor that usually occurs in the long bones of young adults. Its symptoms can be diverse depending on the location of the tumor and especially difficult to diagnose when occurring in an atypical location. Osteoid osteoma arising in the sacrum is extremely rare, and here, we present a case that was treated successfully in a minimally invasive fashion under computed tomography guidance.
