Three projects

Project I title: Closed Reduction of Developmental Dislocation of the Hip: A Follow-Up Study

Human subjects IRB approved project number (where applicable): 0303-130

Animal subjects IRB approved project number (where applicable): N/A

Project Type: Patient-based Research

Brief Description of Project:

The purpose of this study is to identify factors which influence the outcome of developmentally dislocated hips (DDH) treated by closed reduction. Additionally, we will determine what, if any, affect age (presence of ossific nucleus), Tonnis stage, the use of preoperative traction or previous treatment have on radiographic outcome.

Charts and radiographs will be reviewed to determine demographic and clinical data as well as radiographic outcome. All patients who were not skeletally mature (Risser 4 or 5) at the time of their last radiograph and have not had x-rays in the last year, will be contacted and asked to return for a current AP pelvis radiograph.

Project II title: Outcome of Open Reduction for Treatment of Developmental Dislocation of the Hip in the Older Child

Human subjects IRB approved project number (where applicable): 12-02-694

Animal subjects IRB approved project number (where applicable): n/a

Project Type Patient based research

Brief Description of Project:

Purpose: To compare the outcome of primary open reduction of developmental dislocation of the hip performed in patients age four to six with those patients greater than six years of age.

The results of all patients greater than four years of age at the time of initial open reduction of the hip will be studied. Charts and radiographs will be reviewed to determine demographic and clinical data as well as radiographic outcome. An attempt will be made to contact all patients to return for repeat assessment including: a functional outcome questionnaire, physical exam and radiographs (ap pelvis, false profile and, if indicated, [clinical limb length inequality >1 cm] a scanogram). Informed Consent will be obtained on those patients who agree to return for the repeat assessment.

Project III title: Results of Spinal Osteotomies in Children and Adolescents

Human subjects IRB approved project number (where applicable): 1103-706

Animal subjects IRB approved project number (where applicable): n/a

Project Type: Patient based research

Brief Description of Project:

Purpose: The purpose of this study is to assess the clinical and radiographic results of spinal osteotomies in children and adolescents.

Medical records and radiographs will be reviewed on all patients treated at Texas Scottish Rite Hospital who have undergone a spinal osteotomy for correction of deformity following spinal fusion. Medical records will be reviewed to determine the surgical indications, as well as intra- and peri - operative complications (including spinal cord monitoring, blood loss, transfusion needs, length of ICU and overall hospital stay) and clinical outcomes (including neurologic changes). Pre- and Post- operative and Final Follow-up radiographs will be reviewed in the coronal and sagittal planes to determine the amount of correction obtained as well as changes in global spinal balance.
