Arthroscopically Assisted Versus Open Surgical Reduction of the Hip in Patients With Irreducible DDH Before the Walking Age

Not Applicable
Not yet recruiting
Conditions
Developmental Dysplasia of the Hip
Interventions
Procedure: open surgical reduction
Procedure: arthroscopically assisted
Registration Number
NCT06408987
Lead Sponsor
Assiut University
Brief Summary

To determine the role of arthroscopy in treatment of the DDH.

Detailed Description

* The term developmental dysplasia of the hip (DDH) is composed of a spectrum of pathologies from stable acetabular dysplasia (femoral head centered in acetabulum but acetabulum is shallow) to concentric hips that are unstable (femoral head can be moved in and out of the confines of the acetabulum) and frankly dislocated hips in which there is a complete loss of contact between the femoral head and acetabulum.

* Open reduction , traditionally through a Smith - Peterson approach should be considered only if closed reduction cannot be performed.

* Medial open surgical reduction is a choice for the management of patients younger than 18 months with DDH. The minimal incision and minimal blood loss are advantages of this approach. Limited exposure of the hip joint is a disadvantage.

* The arthroscopic procedure was reported to represent a meaningful alternative to the open procedure due to a lower complication rate, a safe setting, a lower rate of residual dysplasia, no observed redislocation and low rate occurrence of osteonecrosis.

* All the intra-articular structures (hypertrophic ligamentum teres, transverse acetabular ligament, and pulvinar tissue) in the acetabulum that impede the reduction of the femoral head could be eliminated by using the arthroscopic technique.
