Summary
Posteromedial soft tissue release, including adductor longus and iliopsoas tendons, in developmental dysplasia of the hip (DDH) patients did not cause major gait changes. Gait analysis showed minor differences, but no significant clinical alterations were observed.
Area of Science:
- Orthopedic surgery
- Pediatric orthopedics
- Biomechanical analysis
Background:
- Soft tissue release, including iliopsoas and adductor tendons, is common in treating developmental dysplasia of the hip (DDH).
- These tendons can obstruct femoral head relocation into the acetabulum.
Purpose of the Study:
- To evaluate the impact of posteromedial soft tissue release (adductor longus and iliopsoas tendons) on hip joint biomechanics and gait patterns in DDH patients.
- To determine if surgical release leads to significant gait alterations.
Main Methods:
- 3-D quantitative gait analysis was performed on 10 patients (mean age, 8.1 years) who underwent unilateral surgical treatment for DDH before 18 months of age.
- Gait parameters, including joint angles and moments, were compared to a healthy control group.
Main Results:
- Patients showed a shorter single support time on the unaffected side compared to controls.
- Increased pelvic excursions (frontal and sagittal planes) and knee extension were observed in patients.
- Minor reductions in peak hip flexion moment and a delayed moment crossover point were noted, but without clear explanation from limited data.
Conclusions:
- Sectioning of the adductor longus and iliopsoas tendons in DDH patients treated before 18 months of age did not result in major objective clinical gait alterations.
- While some minor deviations in gait parameters were detected, they did not appear to be clinically significant.
