We present here an operative method that uses the suture anchor technique in the case of a tiny avulsion fracture of the acetabulum along with a labral tear. Generally it is very difficult to determine how to treat patient with either the conservative method or the operative method because it is difficult to decide on the proper method to fix tiny avulsion fracture fragments to the acetabulum. Unstable hip dislocation was perceived in our case, so we tried to fix the fracture fragments to the acetabular rim&repair the labral tear that was seen on the operation field by using the sutue anchor technique. This is now a popular method to repair labral tear of the shoulder joint.
