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

Conditions

Developmental Dysplasia of the Hip

Outcome Measures

Primary Outcomes (2)

• Operative time of capsulorrhaphy

  calculate the time needed to close the capsule of the hip

  1 year

• Number of stitches taken during capsulorrhaphy

  1 year

Secondary Outcomes (2)

• Modified Mackay's criteria as a clinical evaluation method

  1 year

• any complication detected

  1 year

Study Arms (2)

U-shaped group

ACTIVE COMPARATOR

Participants on which U shaped capsular incision will be used during capsulorrhaphy

Procedure: U shaped capsular incision during capsulorrhaphy

T-shaped group

ACTIVE COMPARATOR

Participants on which T shaped incision will be used during capsulorrhaphy

Procedure: T-shaped capsular incision diuring capsulorraphy

Interventions

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

Also known as: U-shaped Capsulotomy

U-shaped group

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.

Also known as: T-shaped Capsulotomy

T-shaped group
