Biomechanical Assessment of Level Gait in Patient's Status Post Bladder Exstrophy

• Demographic Data:age;GA at birth; Prenatal DX;closure age;Pelvic osteotomies;Perioperative and late complications;Successful initial closure;Continence; Additional surgeries w/age [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]
• Pediatric Outcomes Data Collection Instrument (PODCI) [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]

The purpose of this study is to determine whether patients who have undergone exstrophy closure may be at risk for long-term orthopedic issues manifest by gait abnormalities. This study is a descriptive analysis of the study cohort's gait patterns and pelvic structure.

Specific Aim 1: to determine whether patients with classic bladder exstrophy who underwent closure demonstrate gait abnormalities.

Hypothesis 1: Patients undergoing closure of bladder exstrophy (with or without pelvic osteotomy) demonstrate gait abnormalities compared with a reference population.

Hypothesis 2: Patients undergoing closure of bladder exstrophy (with or without pelvic osteotomy) will have below normal functional survey scores.
