About

The goal of this clinical trial is to compare the postoperative clinical outcome of iliopsoas tenotomy in open reduction operation for developmental dysplasia of the hip. The main aim is to compare the postoperative clinical outcome of division of iliopsoas tendon at two levels, proximally at the pelvic brim and distally just above the lesser trochanter.

Full description

All the patients with DDH included in the current study underwent open reduction of their dislocated hip through the anterior approach. None of the included patients underwent hip surgery through the medial approach.

For the proximal level of psoas tenotomy at the pelvic brim, the hip was slightly flexed to relax the iliopsoas muscle; the iliacus muscle fibers were retracted anteriorly until the deeply seated posteromedially psoas tendon was isolated and transected. For the distal level of iliopsoas tenotomy just above the lesser trochanter, the thigh was put in the position of FABER (flexion, abduction, and external rotation). A curved right-angle hemostatic clamp was used to retract and bring the iliopsoas tendon into the field. Then, the tendinous fibers were transected.

Enrollment: 54 patients

Sex: All

Ages: 1 to 8 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Children with DDH.
• Required open reduction of their hip problem.

Exclusion criteria

• Patients who underwent hip surgery without the need for sectioning the iliopsoas tendon.
• Children with mental retardation who were not cooperative in the assessment of the hip flexion strength.

Group 1

Experimental group

Description:

For the proximal level of psoas tenotomy at the pelvic brim, the hip was slightly flexed to relax the iliopsoas muscle; the iliacus muscle fibers were retracted anteriorly until the deeply seated posteromedially psoas tendon was isolated and transected

Treatment:

Procedure: Proximal level

Group 2

Active Comparator group

Description:

. For the distal level of iliopsoas tenotomy just above the lesser trochanter, the thigh was put in the position of FABER (flexion, abduction, and external rotation). A curved right-angle hemostatic clamp was used to retract and bring the iliopsoas tendon into the field. Then, the tendinous fibers were transected.

Treatment:

Procedure: Distal level
