Do We Need to Change Hip Spica Halfway Through Immobilization Following Closed Reduction for Developmental Dysplasia of the Hip

Objectives: Closed reduction (CR) is a well-established method for treating developmental dysplasia of the hip (DDH). Traditionally, child placed in spica cast after DDH CR three to four months and it common practice change under general anesthesia 6–8 weeks. To our knowledge, no previous studies have shown that changing necessary. We hypothesize there need can be safely retained without any significant complications.
 Methods: used department database find all children who had minimum 90 days over one-year period (March 2018 March 2019) at least one year follow up removal cast. retrospectively reviewed medical notes radiographs, looking complications may attributed prolonged use spica.
 Results: Thirty-nine patients (48 hips) met criteria. None developed cast-related during or No abdominal, joint skin were reported throughout treatment. At up, could using months. 
 Conclusion: Changing every weeks benefit exposes infant an unnecessary anesthesia, with risk losing reduction. conclude very safe keep on CR. recommend reflect findings.
