Application of hip herringbone plaster supporting device in treatment of developmental dysplasia of the hip by plaster immobilization

Objective To explore the application of hip herringbone plaster supporting device in treatment of developmental dysplasia of the hip by plaster immobilization. Methods From January to December 2015, 120 children patients to whom hip herringbone plaster immobilization was implemented with hip plaster supporting device were designated as the observation group, while another 98 fixed by hip herringbone plaster with conventional method from January to December 2014 were retrospectively designated as control group. Operating time was compared between the two groups, with treatment effects compared by Mckay Scores. Results Operating time in the observation group was (22.8±9.0) min, while in the control group, (27.0±13.8) min (t=-2.704, P<0.05) ; excellent/fine rate in the observation group was 96.67% (116/120) , while in the control group, 89.90% (89/98) (χ2=4.238, P<0.05) . Conclusions Implementing plaster immobilization by hip herringbone plaster supporting device can shorten operating time and improve treatment effect.
