Spica Brace for Hip Dysplasia
1 in 1,000 babies is born with developmental dysplasia of the hip that can range from a shallow socket, laxity, or dislocation. Initial treatment is with a Pavlik harness which positions the hip with flexion and abduction, which has 90% effectiveness for hips that are shallow or loose and 60-70% effectiveness for hips that are dislocated.   
Hip dysplasia that does not improve with bracing are often treated in the operating room with an arthrogram and placement in a spica cast, sometimes with adductor tendon lengthening. Following surgery, a CT scan or MRI is done to confirm the reduction.
A brace in the shape of a spica cast would reduce the time required for surgery and facilitate adjustments and better hygiene for cast treatment of hip dysplasia.
