Brief Summary

comparison of the outcome between using U-shaped incision and T-shaped incision for capsulorrhaphy in management of Developmental dysplasia of the hip

Detailed Description

Developmental dysplasia of the hip: Developmental dysplasia of the hip is a spectrum of abnormalities of the developing hip joint that ranges from shallowness of the acetabulum to capsular laxity and instability to frank dislocation . Developmental dysplasia of the hip is relatively common, occurring in 1 of 1000 live births.

When surgical intervention is decided, open reduction is needed to remove any obstacle that hinders hip reduction. Capsulorrhaphy is an essential step for minimizing instability of the hip after reduction The classic T-shaped capsular incision is done by two incisions: Vertical limb parallel to femoral neck axis and a transverse one parallel to the inguinal ligament resulting into two layers . Suturing them back is somewhat cumbersome after femoral head reduction. Therefore, the suggested technique utilizes a U-shaped incision to make re-suturing of the capsule easier with multiple stitches, and this study compares the outcome between using T-shaped incision and U-shaped incision for capsulorrhaphy after open reduction Femoral osteotomy or Pelvic osteotomy can be used in certain circumstances.
