OBJECTIVE: In this current study, radiographs were taken to determine whether pelvic distortions could be demonstrated on x-ray when pelvic blocks were placed under the patient in the prone position. METHODS: One patient was placed prone in a neutral position and radiographs were taken in a neutral position, and then with a pair of pelvic blocks placed under the subject in each of 4 different positions: (Right Short Leg - Category One) left iliac crest, right greater trochanter; (Left short Leg - Category One) right iliac crest, left greater trochanter; (SB+) left and right iliac crests; and (SB-) left and right greater trochanters. RESULTS: Findings indicated that pelvic block placement could create or affect distortions of the pelvis. CONCLUSION: Further studies are indicated correlating radiographic analysis, pain provocation, and muscle strength to determine if a clear pelvic block preference can be determined definitively.
