Clinical Trial Summary

The annual number of live births in Türkiye is 1,112,859 in 2020 and the estimated incidence of developmental dysplasia of the hip (DDH) is between 5 and 15 per 1000 live births. The implementation of the National DDH Early Diagnosis and Treatment Program by the Türkiye Republic of the Ministry of Health in 2010 significantly reduced the number of patients with DDH diagnosed more than 6 months later. If not appropriately treated, DDH can cause a decrease in the number of healthy life years, and workforce losses, which consequently burdens the social security system and government budget. The vast majority of clinical trials comprise risk factors associated with complications after treatment of DDH. Moreover, studies involving functional assessments are generally focused on adult DDH patients with surgical indications. To the best of the investigators' knowledge, mid-term patient-reported and performance-based functionality has not been examined in conservatively treated patients. In addition, it is not known whether the diagnosis of unilateral and bilateral DDH in these patients will make a difference in daily activities which require bilateral functionality of the lower limbs. Therefore, in this study, the investigators examined and compared the mid-term patient-reported and performance-based functional outcomes in patients with unilateral and bilateral DDH treated with a hip abduction brace. This study provides new data on mid-term functionality in children with unilateral and bilateral DDH. It can guide determining the lower extremity functional levels of school-age children with DDH, regular follow-up, early diagnosis, and treatment planning for problems.

Moreover, studies involving functional assessments are generally focused on adult DDH patients with surgical indications. To the best of the investigators' knowledge, mid-term patient-reported and performance-based functionality has not been examined in conservatively treated patients. In addition, it is not known whether the diagnosis of unilateral and bilateral DDH in these patients will make a difference in activities such as jumping rope, double-leg jumping, walking, and dynamic balance, which require bilateral functionality of the lower limbs. Therefore, the aim of this study is to examine and compare the mid-term patient-reported and performance-based functional outcomes in patients with unilateral and bilateral DDH treated with a hip abduction brace.

Outcome

Type Measure Description Time frame Safety issue
Primary Radiographs Standard pelvic AP radiographs taken at the first and last admission of the patients were used for radiological evaluation. The acetabular index angle of Hilgenreiner and the centeredge angle of Wiberg were measured. The Tönnis radiographic classification was used for patients with ossified femoral head, and the IHDI classification was used for other patients. 2 hours
Primary Lower Extremity Functional Scale Lower Extremity Functional Scale was used for assess functional status in musculoskeletal dysfunction affecting the lower extremities. The scale mainly consists of 20-items and is a 5-point Likert type (0 = extreme difficulty or or unable to perform activity and 4 = no difficulty). Total score ranged from 0 to 80 points, with higher scores indicating better functional status. 30 minutes
Primary 10 meters walking test 10 meters walking test was used for assessing the walking speed over a distance of 10 meters 10 minutes
Primary Double-leg vertical jump test The double-leg vertical jump test was used to determine the strength and functional characteristics of the lower extremity extensor muscles. Participants stood upright with feet positioned shoulder width apart, and hands at their hips (to reduce the impact of arm movement). Patients were instructed to jump as high as possible with both legs. 15 minutes
Primary Jump rope Jump rope assesses the strength of the lower extremity muscles. Patients were asked to jump rope for 60 seconds and the number of repetitions was recorded 10 minutes
Primary STAR excursion balance test STAR excursion balance test was used to measure dynamic balance in children. The test was performed with both extremities. In order to reduce the time required to perform the test, reach in 3 directions was measured anterior, posteromedial, and posterolateral, respectively. To normalize the distances reached, the reach distance was divided by the leg length and multiplied by 100. 10 minutes
