Case History and Examination
The patient was a 22-year-old female Caucasian (height 160cm, weight 70kg) living in the United Kingdom (UK) with bilateral Developmental Dysplasia of the Hip (DDH) with a radiographic Lateral Centre Edge Angle (LCEA) of 15º on the right and 17º. A LCEA of < 20º is considered to be dysplastic [26]. She had been referred for pre-operative physiotherapy by her hip surgeon, in preparation for a right hip peri-acetabular osteotomy [27]. The right hip operation was scheduled in 16 weeks’ time and the left hip operation a year later; providing surgical outcomes were satisfactory on the right side. The patient has formally consented to her case being published, having considered and approved this manuscript.
