Official title
Function of Ligamentum Teres in Management of Developmental Hip Dysplasia (DDH)
Overview
Treatment of developmental dysplasia of the hip (DDH) is still challenging, till now there is no any recent advances have refined our understanding of how best to survey for the condition during infancy and refine the selection of patients who can best benefit from hip preservation surgery.
Detailed description
Concentric positioning of femoral head into the acetabular cavity and adequate balance in growth between tri-radiate and acetabular cartilage are leading to adequate growth and development of the hip. Any alteration in these two conditions leads to a hip dysplasia \& dislocation .
Treatment of developmental dysplasia of the hip (DDH) is still challenging, till now there is no any recent advances have refined our understanding of how best to survey for the condition during infancy and refine the selection of patients who can best benefit from hip preservation surgery.
The ideal continued target would be to prevent missed hip dislocations or dysplasia during the infant period, decrease the incidence of total hip arthroplasty in adulthood related to undertreat DDH and prevent avascular necrosis (AVN).
The goal of the treatment is to achieve a concentric reduction of the femoral head into the acetabulum.
Interventions
- Procedure ligamentum teres tenodesis
* Creating a tract or tunnel: from acetabulum cavity to intra pelvic cavity using bit (3.5mm or 4.5mm according to the size of the ligament) or k wire (3mm) from the site of the ligamentum attached at the acetabulum guided with passer * Passing of the sutured ligamentum teres through the tunnel * Tighting of the passed sutured ligamentum teres
Primary outcome measures
- modified Harris Hip Score [Time frame: 6 months]
