Radiological evaluation of combined valgus extension osteotomy and tectoplasty for the treatment of Herring group C Perthes patients.

Objectives: In this study we evaluated the results of combined proximal femoral valgus extension osteotomy and tectoplasty in the treatment of Herring group C Perthes disease with hinge abduction.

Patients And Methods: This study was carried out in 11 male patients who underwent combined proximal femoral valgus extension osteotomy and tectoplasty for hinge abduction related to Perthes disease between January 2002 and February 2009. All patients were assessed as group C according to the Herring lateral pillar classification.

MDCT with multiplanar reconstruction in the preoperative local staging of rectal tumor.

Objective: To evaluate the accuracy of MDCT with multiplanar reconstruction in the preoperative local staging of rectal tumor.

Materials And Methods: Thirty-seven patients with rectal tumor underwent preoperative MDCT. Two radiologists evaluated the depth of tumor invasion (T staging), regional lymph node involvement (N staging) and mesorectal fascia involvement on axial, sagittal, and coronal multiplanar reconstruction images in consensus.
