This past year has seen an increase in the quality of studies in pediatric orthopaedics, and the completion of BrAIST demonstrated that high-level studies of important questions can be addressed in pediatric orthopaedics. The current commitment of improving quality of care for children promises a healthy future for pediatric orthopaedics.
BACKGROUND Questions remain as to the effect of pedicle screws on spinal canal development in young children. The purpose of this study was to determine the effects of unilateral placement of dual screws across the neurocentral synchondrosis on spinal canal development as assessed with histological analysis and measurement of the canal dimensions in an… (More)
Anterior spinal instrumentation is an alternative option to posterior instrumentation for surgical treatment of adolescent idiopathic scoliosis (AIS). However, optimal instrumentation configuration and strategies are not yet clearly defined. A biomechanical kinematic model using flexible mechanism was developed to study instrumentation strategies.… (More)
BACKGROUND The reported prevalence of non-neurologic complications following corrective surgery for adolescent idiopathic scoliosis ranges from 0% to 10%. However, most studies were retrospective evaluations of treatment techniques and did not focus solely on complications. The purpose of this study was to determine the prevalence of non-neurologic… (More)
STUDY DESIGN A retrospective analysis of patients who had magnetic resonance imaging (MRI) of the thoracic spine, comparing those with a normal straight spine and those with a right thoracic adolescent idiopathic scoliosis (AIS). OBJECTIVE To analyze the position of the rib head with respect to the spinal canal and vertebral body in normal patients and… (More)
STUDY DESIGN Manual digital measurements, in a porcine model of thoracoscopic anterior instrumentation, divided into two studies: 1) comparing the actual screw position within each vertebra with the perceived ideal screw position and correlation with the learning curve of the surgeon; and 2) a quantitative analysis of the vertebral bodies from T3 to T12 to… (More)
BACKGROUND A congruent hip frequently is cited in the literature as a prerequisite for performing a reconstructive pelvic osteotomy for hip dysplasia. The designation as congruent is important as incongruent joints generally are regarded as requiring a salvage-type procedure. Several measures of congruency are described in the literature, but it is unclear… (More)
Corrective forces during spine deformity surgery, including distraction, impart significant stresses to the spinal cord that may result in permanent injury. Intraoperative neuromonitoring is commonly used by surgeons to recognize possible damage to the spinal cord in cases of evident traumatic or vascular damage to the spinal cord. However, mild insult to… (More)
