The Importance of Allis Maneuver in the Management of Traumatic Posterior Hip Dislocation in Children: A Report of Two Cases

Abstract

Background: Traumatic hip dislocation happens infrequently in children. Prompt diagnosis and management are crucial to prevent complications such as osteonecrosis, osteoarthritis, and recurrent dislocation. Case presentation:In this report, we have presented two pediatric cases of posterior traumatic hip dislocation with 5 and 6 years of age. The diagnoses were made based on the history of trauma, symptoms, and anteroposterior hip radiographs. The closed reduction in both cases was achieved with the Allis maneuver. There was no sign of joint widening in post-reduction radiographs. A 4-week Spica cast was used for immobilization and an immediate weight-bearing was advised after the cast removal. During the two-year follow-up period, the patients regained full recovery without any complications. Conclusion:The Allis maneuver can be used as a reliable alternative for joint reduction when the gentle traction method is not successful. To exclude incomplete reduction, a post-reduction radiograph is needed, followed by a CT or MRI in the presence of any joint widening.

Rupture of External Iliac Artery during Total Hip Arthroplasty after Rotational Acetabular Osteotomy: A Case Report

“…The reduction generally is a closed procedure, but if irreducible or incongruently reduced warrants an open procedure [ 10 ]. Reduction maneuver for pediatric dislocation involves a gentle traction, but in few reported cases, Allis maneuver was needed [ 11 ]. We in our case also performed Allis maneuver to reduce the hip, as it was not reducible with traction.…”
