AbstractTraumatic dislocation of the hip is rare in children. Complications occur in cases with associated injuries and delayed treatment. Treatment options are limited in case of avascular necrosis. We report a case of 6 year old girl who presented with stiffness and deformity of left hip with increased lumbar lordosis and inability to walk due to a post traumatic AVN that happened after a traumatic hip dislocation at the age of 18 months. She successfully underwent head reduction osteotomy, utilizing pre-op 3D-printed models. The procedure was successful in terms of correcting her deformities, relieving pain and her ability to ambulate after 3 years of follow up. This case suggests that femoral head reduction osteotomy, with minimal modifications, can be performed in children as young as 6-years old. 3D-modeling is a great addition to the tools a surgeon can use, in the preoperative planning of difficult osteotomies, as well as education of the residents and fellows. Level of Evidence: Therapeutic Level V – Case reportFunding: No funding was received for this study.

Background: Dislocation of total hip arthroplasty may happen for different reasons. Abnormal acetabular orientation is a common reason for such occurance. We would like to report the effect of acetabular inclination on incidence of dislocation.Methods: In a cross-sectional study all cases of total hip arthroplasty performed in a 2-yaer interval in one educational hospital in Tehran, were followed and assessed for possible dislocation in a 18.1 months (3-25 months) of follow-up. The inclination angles of acetabular components were measured, and the relationship of dislocation with gender, age and this angle was evaluated.Results: 132 cases entered the study. 4 patients (3%) encountered dislocation and all 4 had inclination angles of over 50 degrees. Gerder did not seem to play an important role. Older age, however, was probably contributing to risk of dislocation.Conclusion: Inclination angle of over 50 degree in acetabular component position is one of the factors making it more likely for the hip arthroplasty to dislocate.
