PURPOSE Past epidemiological studies demonstrated a nearly fivefold lower incidence of slipped capital femoral epiphysis (SCFE) in New Mexico compared with Connecticut. A recent study demonstrated some regional variability but did not address this earlier finding. We sought to reexamine the incidence of SCFE in New Mexico to improve the understanding of the(More)
BACKGROUND Closed reduction and percutaneous pin fixation is the recommended treatment of displaced (Gartland types 2 and 3) supracondylar humerus fractures. The need for a medial pin for maximal stability remains controversial. The purpose of this study was to develop a model of supracondylar humerus fractures simulating medial column comminution and to(More)
STUDY DESIGN A retrospective review of medical records and imaging studies of children diagnosed with spinal cord injury without radiographic abnormality (SCIWORA) or SCIWORA-like symptoms at Children's Hospital of Pittsburgh between 1965 and 1999 was undertaken. OBJECTIVES To evaluate the existence of occult segmental spinal instability and a role for(More)
BACKGROUND Nonoperative management of clubfoot with the Ponseti method has proven to be effective, and it is the accepted initial form of treatment. Although several studies have shown that problems with compliance with the brace protocol are principally responsible for recurrence, no distinction has been made with regard to whether the distance from the(More)
STUDY DESIGN Case controlled study. OBJECTIVE To explore the relative effects of body mass index (BMI) and the presence or absence of adolescent idiopathic scoliosis (AIS) on bone mineral density (BMD) as evidenced by Z-scores in adolescents. SUMMARY OF BACKGROUND DATA Prior studies have identified adolescents with idiopathic scoliosis as having(More)
Controversy exists concerning pin placement for supracondylar humerus fractures in children. Both crossed pin and lateral only pin configurations have shown good results; however, prospective studies are lacking. We present a prospective, surgeon-randomized study comparing crossed pin (group A, n = 20) versus preferential lateral only pin (group B, n = 20)(More)
STUDY DESIGN Retrospective case series. OBJECTIVE This study evaluated the incidence of postoperative neurological symptoms after a freehand pedicle screw insertion technique in idiopathic posterior scoliosis surgery. SUMMARY OF BACKGROUND DATA It is generally accepted that pedicle screws can be inserted by a freehand technique in the thoracic and(More)
PURPOSE Posterior only approaches for spinal deformity are increasingly popular and posterior spinal release is utilized to gain flexibility for correctional maneuvers. Prior biomechanical data support the use of facetectomy and rib head resection for gaining flexibility in the sagittal and coronal planes but to date there has been no quantification of(More)
STUDY DESIGN Biomechanical cadaver study. OBJECTIVE To evaluate the relative effectiveness of Ponte osteotomies for spinal release in deformity correction. SUMMARY OF BACKGROUND DATA Controversy exists as to the role of Ponte osteotomy in deformity correction surgery. Very little has been written about the biomechanical effects of Ponte osteotomy.
