Surgical Treatment of Congenital and Obligatory Dislocation of the Patella in Children.

Background: Congenital (fixed) dislocations and obligatory (habitual) patellar dislocations represent a complex clinical and surgical challenge. Numerous treatment options, offering different perspectives, and surgical solutions are reported in the literature.We implemented the surgical technique principles, originally described by Stanisavljevic, for congenital (fixed) and obligatory (habitual) patellar dislocations, with slight modifications.

A new pelvic rod system for the surgical correction and fixation of pelvic obliquity in pediatric neuromuscular scoliosis.

Purpose: To describe surgical outcomes using the new device in pediatric neuromuscular scoliosis.

Methods: All patients with neuromuscular disorders requiring surgery with pelvic fixation for the correction of scoliosis in the period 2002-2009 were operated by the new pelvic rod fixation device. Coronal and sagittal alignment before and after surgery until the latest follow-up were evaluated by standard X-rays.

Intra- and interobserver reliability analysis of digital radiographic measurements for pediatric orthopedic parameters using a novel PACS integrated computer software program.

Background: The between-observer reliability of repeated anatomic assessments in pediatric orthopedics relies on the precise definition of bony landmarks for measuring angles, indexes, and lengths of joints, limbs, and spine. We have analyzed intra- and interobserver reliability with a new digital measurement system (TraumaCad Wizard™).

Methods: Five pediatric orthopedic surgeons measured 50 digital radiographs on three separate days using the TraumaCad system.

The contribution of an electronic conductivity device to the safety of pedicle screw insertion in scoliosis surgery.

Study Design: Retrospective, controlled clinical study.

Objective: To evaluate the contribution of an electronic conductivity device (ECD) to the safety of pedicle screw insertion in pediatric scoliosis surgery.

Summary Of Background Data: The implantation of pedicle screws in spinal deformity correction surgery has evolved into the currently predominant fixation technique.

[Practical significance of sonographic type IIa of dysplastic hip joint according to Graf's classifications].

Hip joint assessment in newborns and neonates is currently performed with ultrasonography due to the high degree of sensitivity and specificity of this technology as compared to the usual radiography. Measuring the alpha and beta angles is indicative in assessing the hip joint. The alpha angle represents the bony acetabular components and the beta angle represents the cartilaginous roof.
