After 11 years, the right hip was very mobile and without any pain, and radiographic follow-up was within normal limits (Fig. 1).

However, antero-posterior and lateral radiographs revealed a bone density reduction in the left greater trochanter and mild bone rarefaction of the acetabular cup on the medial side (Fig. 2).
(A) Creamy lead grey material spurted out from the hip articulation, occupying most part of trochanteric area. (B) The lytic area was filled with demineralized bone matrix (DBX).

Creamy lead gray material spurted out from the hip articulation, occupying most part of trochanteric area (Fig. 3A). The remaining lytic area was filled with 11 cc of demineralized bone matrix (DBX by Synthes) and closed with the residual thin trochanteric wall (Fig. 3B).
30 months X-ray follow-up.

At radiographic control (2 months after surgery), trochanteric lysis was no more visible and periarticular ossifications were evident (Fig. 4). Radiographic control did not show any variation from the post-operative one, as was the case after 30 months (Fig. 4).
