ABSTRACT
Patients with Turner syndrome (TS) frequently show short stature and skeletal deformities, such as kyphosis and scoliosis. However, to the best of our knowledge, limb length discrepancy (LLD) has not yet been reported in patients with TS. The case of a 12-yr-old girl with 45,X/47,XXX mosaic TS showing LLD is herein presented. She was on GH therapy for short stature and was noted to have scoliosis in the standing position at a regular examination; however, the scoliosis became less evident in the supine position, which is indicative of LLD. The length of the left leg was 5.0 cm shorter than that of the right leg when measured. She was referred to orthopedics and underwent right distal femoral and right proximal tibial staple epiphysiodesis to shorten the abnormally long limb at 10 yr 6 mo of age. One year after the operation, the LLD decreased from 5.0 to 1.5 cm. During this period, GH was continued. LLD is a rare complication in TS, but when patients with TS show scoliosis in the standing position, re-evaluation for scoliosis in the supine position should be performed and the lengths of both legs should be measured.
