In patients with scoliosis, the morphology of the pedicles differs from those in normal spines. Preoperative three-dimensional information of these complex anatomic situations means a great advantage for the surgeon in order to assess which pedicles can be instrumented safely avoiding screw misplacement and for the decisions in choosing the appropriate screw size. The objective of this study was to measure pedicle dimensions in scoliotic spines on three-dimensional computed tomographic (CT) scans and to determine the intra- and interobserver reliability of the method. Additionally, the pedicles that cannot be instrumented safely by available screws were identified. ⋯ Measurement of pedicle dimensions on three-dimensional CT scans is a reliable but time-consuming procedure to assess pedicle dimensions. CT measuring should be reserved for special cases, where the anatomic situation remains unclear despite X-ray. In scoliotic spines, one-third of the mid-thoracic pedicles cannot be instrumented safely with pedicle screws.

We evaluated the reliability and validity of an adapted Korean version of the Scoliosis Research Society-22 (SRS-22) questionnaire. ⋯ The adapted Korean version of the SRS-22 questionnaire was successfully translated and showed acceptable measurement properties, and as such, is considered suitable for treatment outcome assessments in the Korean-speaking patients with idiopathic scoliosis.

A total of 16 patients with severe and rigid idiopathic scoliosis treated by anterior and posterior vertebral column resection (APVCR) were retrospectively reviewed after a minimum follow-up of 2 years. The indication for APVCR was scoliosis more than 90° with flexibility less than 20%. The radiographic parameters were evaluated, and clinical records were reviewed. ⋯ Malposition of titanium mesh cage happened to two patients. There were no neurological complications, deep wound infections or pseudarthrosis. APVCR is an effective alternative for severe and rigid idiopathic scoliosis.

The aim of the article is fourfold; firstly, to detect the aetiology of torticollis in patients with Müllerian duct/renal aplasia-cervicothoracic somite dysplasia syndrome; secondly, spine pathology in Müllerian duct/renal aplasia-cervicothoracic somite dysplasia syndrome varies considerably from one patient to another and there are remarkable differences in severity and localization; thirdly, mismanagement of congenital spine pathology is a frequent cause of morbid/fatal outcome; and fourthly, the application of prophylactic surgical treatment to balance the growth of the spine at an early stage is mandatory. Reformatted CT scans helped in exploring the craniocervical and the entire spine in these patients. ⋯ Pelvic ultrasound showed the classical renal agenesis in four patients; whereas in one patient, the MRI showed pelvic cake kidney (renal fused ectopia) associated with ovarian, uterine and vaginal abnormalities. This is the first exploratory study on the craniocervical and the entire spine in a group of patients with MURCS association.
