The morphometrical and topographical evaluation of the superior gluteal nerve in the prenatal period.

Introduction: Advances in medical science are helping to break down the barriers to surgery. In the near future, neonatal or in utero operations will become the standard for the treatment of defects in the human motor system. In order to carry out such procedures properly, detailed knowledge of fetal anatomy is necessary.

Partial breakage of a tunneled dialysis catheter: An uncommon finding.

Infections and dysfunction are the most common complications related to catheter use. Here we describe a case of catheter rupture on the course of subcutaneous channel. Catheter fractures are relatively rare, but potentially hazardous complications.

Diffusion tensor imaging of normal-appearing cervical spinal cords in patients with multiple sclerosis: Correlations with clinical evaluation and cerebral diffusion tensor imaging changes. Preliminary experience.

Background: Several studies have identified changes in the spinal cord DTI measurements in patients with multiple sclerosis (MS). However, correlations between changes in DTI parameters in normal appearing cervical spine and neurological findings have not been clearly established.

Objectives: To determine whether diffusion tensor imaging (DTI) measurements such as fractional anisotropy (FA) and apparent diffusion coefficient (ADC) are sufficiently sensitive in detecting microstructure alterations in normal-appearing spinal cords in patients with MS and whether they reflect these patients' clinical disability.

Functional recovery after surgical stabilization and postoperative radiotherapy due to metastases of long bones.

Purpose: To reinvestigate the functional recovery after combined treatment with surgery and postoperative irradiation of complete or impending pathologic fractures of long bones.

Methods: We retrospectively evaluated the results of external beam radiation therapy (EBRT) carried out after 68 orthopedic stabilization procedures (femur, n = 55, 80.8%; humerus, n = 13, 19.

Increased Radiation but No Benefits in Pedicle Screw Accuracy With Navigation versus a Freehand Technique in Scoliosis Surgery.

Background: The clinical value of pedicle screws in spinal deformity surgery is well known; however, screw insertion is demanding and sometimes associated with complications. Navigation systems based on intraoperatively obtained three-dimensional (3-D) images were developed to minimize pedicle screw misplacements. However, there is a lack of data confirming superiority of navigation above other techniques.

The impact of direct vertebral rotation (DVR) on radiographic outcome in surgical correction of idiopathic scoliosis.

Introduction: Recent developments of spinal instruments allow to address nearly all components of idiopathic scoliosis. Direct vertebral rotation (DVR) maneuver was introduced to correct apical axial vertebral rotation. It is however still not well established how efficiently DVR affects results of scoliosis correction.

Radiotherapy, Bisphosphonates and Surgical Stabilization of Complete or Impending Pathologic Fractures in Patients with Metastatic Bone Disease.

Purpose: To report the treatment outcomes of patients with metastatic bone disease with complete or impending pathologic fractures, who were treated with postoperative radiotherapy (RT), bisphosphonates or both after orthopedic stabilization.

Material And Methods: We retrospectively evaluated the results of RT, bisphosphonates or both after orthopedic stabilization for complete or impending pathologic fractures in 72 patients with skeletal metastases. After surgery, 32 patients (44%) were treated with RT alone (group 1), 31 patients (43%) were treated with RT and bisphosphonates (group 2) and 9 (13%) patients were treated with bisphosphonates (group 3), respectively.
