Objectives: This study was carried out to investigate the relationship of leg length analysis and X-ray finding according to positions and valuation bases on diagnosis of pelvic malpositions. Methods: Twenty-two people who get 33.09±10.73 as average were evaluated by leg length analysis and X-ray findings. After measuring innominate measurement(IM), femur head line. distance between S2 and posterior superior iliac spine(PSIS). ilium shadow measurement(ISM), major axis of obturator foramen(MaF), minor axis of obturator foramen(MiF) and distance between off centering measurement and symphysis pubis, those were analyzed. Results: 1. In assessment of posterior rotation malposition ilium(PI), it was showed the best coincidence between leg length analysis and X-ray analyzed by 1M in supine position(11 cases, 50.5%). 2. In assessment of inflare, coincidence index between leg length analysis and X-ray were not good(4.00±3.03 cases, 18.15±13.82%). And leg length analysis were not sensitive. 3. On the whole, coincidence index between leg length analysis and X-ray were not good(best: 1 case, 45.5%; worst: 11 cases, 50.0%). Conclusions: Results form this investigation showed the relationship of leg length analysis and X-ray according 10 positions and valuation bases on diagnosis of pelvic malpositions. This results are expected to contribute to establish method of assessment in diagnosis of pelvic malpositions.
