Note:
The losses in volume for individual thigh muscles from pre-operative to post-operative assessments. The average loss is measured in cubic centimeters (cm3), with adjusted muscle volumes normalized by the square of the patient’s height (volume/height2). The ratio values provide a comparative analysis of muscle volume losses between different types of hip fractures. To discern which hip fracture type corresponds to greater muscle volume disparities, the percentage differences for each individual muscle relative to the alternate fracture type are calculated and presented.
