Objectives: The aim of this study was to investigate the wholeness, thickness, and elastography measurements of the iliopsoas tendon using shear wave elastography who underwent open reduction surgery for unilateral developmental dysplasia of the hip. Patients and methods: Between January 2011 and December 2016, a total of 15 patients (2 males, 13 females; mean age: 24.6 +/- 26.3 months; range, 3 to 98 months) who underwent surgical treatment for unilateral DDH were retrospectively analyzed. In addition to demographic data, clinical findings such as muscle strength, range of motion, and the presence of limping were recorded. Ultrasound elastography was used to examine the thickness, shear wave velocity and elasticity of the iliopsoas tendons. Results: The mean follow-up was 92.6 +/- 30.2 (range, 44 to 120) months. Full range of motion of the hips was observed in all patients. Hip flexor muscles' strength was 5/5 in bilateral. No hip dislocation or limping was not detected in any of the patients. Ultrasound examinations revealed that tenotomized iliopsoas tendons were intact in all patients. The mean muscle thickness was lower in operated sides, indicating no statistically significant difference. The mean velocity and elasticity were statistically significantly higher in the operated sides. Conclusion: This is the first study using shear wave ultrasonography for iliopsoas tenotomy of the patients underwent open reduction for developmental hip dysplasia. Re-adhesion of the iliopsoas tendons provided wholeness while healing as a more rigid and thinner structure compared to the intact sides.
