Comparison of the surgical efficacy of robot-assisted and freehand nail placement in the treatment of sarcopenia combined with femoral neck fractures younger than 65 years

A total of 127 participants were enrolled in this study, with 46 individuals in the RG group and 81 in the FG group. Across both groups, factors such as gender, age, SMI, injury sides, Garden classifications, intraoperative blood loss, preoperative CRP, and VAS scores at 6 months post-surgery did not show statistically significant differences (p > 0.05). The RA group exhibited shorter operation time, fewer intraoperative X-ray shots, less needle drilling, and lower postoperative CRP levels compared to the FH group. The VAS score of the RA group was lower one month after surgery, whereas the Harris score was higher six months post-surgery (p < 0.05). The parallel angle of the hollow screws in the RA group was superior to that in the FH screw placement group, with an earlier time to bear weight on the ground post-surgery (p < 0.05). There were no statistically significant differences in incision infection, femoral neck nonunion (within 9 months after surgery), and patient satisfaction between the two groups (p > 0.05). Furthermore, the rate of femoral head necrosis after fracture within 2 years in the RA group was lower compared to the FH screw placement group, with statistically significant differences (p < 0.05).
