Supplementary Material

Computer software (Excel, Microsoft Office, version 2003,Microsoft, USA) spread sheet that can be used to calculate the allowance angles corresponding to variable retroacetabular angles and tangents for every one mm of medialization distance of screw site. It can be used by any surgeon pre or intraoperatively to determine proper angles for screw trajectory in the posterior acetabular wall.
