Correlation between preoperative CT scan of the paraspinal, psoas, and gluteus muscles and postoperative ambulatory status in patients with femoral neck fractures

Abstract

Abstract Background This study aimed to investigate the relationship between femoral neck fractures and sarcopenia. Methods This was a retrospective analysis of 92 patients with femoral neck fractures who were classified into high ambulatory status (HG) and low ambulatory status (LG) groups. Ambulatory status was assessed before surgery, one week after surgery, at discharge, and during the final follow-up. To evaluate sarcopenia, muscle mass and fatty degeneration of the gluteus medius, gluteus maximus, paraspinal, and psoas muscles were measured using preoperative CT. Results The mass of the gluteus medius and paraspinal muscles was significantly correlated with ambulatory status before the injury, at discharge, and during the final follow-up. Conclusions Measurement of the gluteus medius and paraspinal muscles has the potential to evaluate sarcopenia and predict ambulatory status after femoral neck fractures.
