The purpose of this study is to evaluate the fluid volume required for a saline load test to detect intra-articular involvement of the glenohumeral joint after penetrating trauma. A human cadaver study was conducted with 22 thawed, fresh-frozen forequarter amputations. A standard posterior shoulder portal was made with an 11-blade scalpel. ⋯ Injection volume required for extravasation was recorded. A logarithmic distribution of the volumes was then calculated in order to obtain estimated sensitivity ranges. Using a logarithmic distribution, 90%, 95% and 99% of simulated glenohumeral arthrotomies could be detected using injections of: 62 ml [41-96], 81 ml [50-133] and 136 ml [72-252], respectively.
