The top photo is a picture of the spacer. Everytime I have an xray I ask then if I can photograph the image. Didn't post the whole of the last xray of my entire hips as it looked a bit too pornographic. Took a lovely outline of all my soft tissue but that shows the different lengths too. Screws again i presume is down to the surgeon. My L. hip (the good one) also has screws!
