title: The greater trochanter located in the acetabulum in a girl with developmental dysplasia of the hip: an unusual complication after redislocation.
abstract: Unstable closed reduction often leads to unsatisfied function. Abnormal force transmission after unstable closed reduction can cause pain, episodes of instability and restriction of range of movement. There is a limited number of literature data which suggests overgrown greater trochanteric located in the acetabulum as a false femoral head without any functional deterioration. In this article, we reported a five-year-old girl with developmental dysplasia of the left hip redislocated following closed reduction. After five-years of follow-up, overgrown greater trochanter was located in the left acetabulum and it unexpectedly resulted in a satisfied function. The unforeseen overgrown greater trochanteric as a false femoral head may lead to a satisfactory function at five-years after reduction. However, long-term follow is required, as its role in early-onset degenerative osteoarthritis remains inconclusive.
