The relationship between pelvic block placement and radiographic pelvic analysis

Area of Science:

• Radiological imaging
• Anatomical studies
• Biomechanical analysis

Background:

• Pelvic distortions can impact patient biomechanics and pain.
• Understanding the effects of external supports on pelvic alignment is crucial.

Purpose of the Study:

• To investigate if pelvic blocks, when positioned under a patient in the prone position, can induce measurable pelvic distortions on radiographs.
• To explore the potential of radiographic analysis in detecting block-induced pelvic changes.

Main Methods:

• Radiographs were obtained from a single patient in a neutral prone position.
• Pelvic blocks were applied in four distinct configurations: Right Short Leg (Category One), Left Short Leg (Category One), SB+, and SB-.
• Radiographs were taken with each pelvic block configuration to assess changes.

Main Results:

• Pelvic block placement was found to create or influence distortions in the pelvic structure.
• Radiographic findings demonstrated a correlation between pelvic block application and pelvic alignment changes.

Conclusions:

• Pelvic block placement can demonstrably alter pelvic alignment as visualized on radiographs.
• Further investigation is warranted to correlate radiographic findings with pain provocation and muscle strength to determine optimal pelvic block usage.
