Brief Summary

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.

Conditions

Orthopaedic Surgery

Outcome Measures

Primary Outcomes (1)

• modified Harris Hip Score

  6 months

Interventions

ligamentum teres tenodesis PROCEDURE

* 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

Eligibility Criteria

• Age: 9 Months - 5 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17)
• Sampling Method: Non-Probability Sample

Study Population

Operation was done under general anesthesia and patient in supine position. Sterilization was done. Incision was made from anterior half of iliac crest to ASIS (the anterior or anterolateral Smith-Petersen approach with a modified "bikini" incision) .Superficial dissection was done by identify gap between sartorius and tensor fasciae latae, dissect through subcutaneous fat (avoid lateral femoral cutaneous n.), incise fascia on medial side of tensor fascia latae and detach origin of tensor fasciae latae of iliac to develop internervous plane. Deep dissection was done by identify plane between rectus femoris and gluteus medius and detaches rectus femoris from both its origins.

You may qualify if:

• Virgin developmental dysplasia of the hip (DDH)
• failed closed reduction in the management of DDH and failed open reduction through medial approach in the management of DDH

You may not qualify if:

• cases that managed previously through anterior approach
• old neglected cases above 5 years old children
