About this study

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.

Treatment and study plan

U shaped capsular incision during capsulorrhaphy

Procedure

Incision of the capsule of the hip during open reduction of Developmental Dysplasia of the Hip,Incision is done with its base proximally. The transverse limb is 1 cm proximal to femoral neck base

Other names: U-shaped Capsulotomy

T-shaped capsular incision diuring capsulorraphy

Procedure

Incision of the capsule of the hip during open reduction of Developmental Dysplasia of the Hip done by two incisions: Vertical limb parallel to femoral neck axis and a transverse one parallel to the inguinal ligament resulting into two flabs.

Other names: T-shaped Capsulotomy

Primary outcomes

  1. Operative time of capsulorrhaphy

    Time frame: 1 year

    calculate the time needed to close the capsule of the hip

  2. Number of stitches taken during capsulorrhaphy

    Time frame: 1 year

Secondary outcomes

  1. Modified Mackay's criteria as a clinical evaluation method

    Time frame: 1 year

    Postoperative clinical evaluation Grade 1(Excellent):Painless,stable hip,no limp,more than 15 degrees of internal rotation Grade 2(Good):Painless,stable hip,slight limp or decreased motion;negative trendelenburg's sign Grade 3(Fair):Minimum pain,moderate stiffness;Positive trendelenburg sign Grade 4(Poor):Significant pain
