Abstract
In order to achieve good results following Total hip replacement , proper and reproducible acetabular cup placement is of paramount importance. The safe zone described by Lewwinick is still considered to be the target cup position. Various techniques have been used to improve the precision and accuracy of cup placement including the use of computer navigation which is often prohibitively expensive for developing countries. We present a ‘No touch smartphone technique’ to check positioning of acetabular cup intra operatively, without compromising the sterility of the operative field which we have found to be simple, quick, inexpensive and reproducible.
