Clinical efficacy of manual reverse closed reduction and robot-assisted cannulated screw fixation for valgus-impacted osteoporotic femoral neck fractures in the elderly: a retrospective cohort study
Clinical Report: Efficacy of Manual Reverse Closed Reduction with Robotics
Overview
This study evaluates the efficacy of a dual-optimization strategy combining manual reverse closed reduction with robotic-assisted fixation for osteoporotic femoral neck fractures in elderly patients.
Background
Hip fractures, particularly femoral neck fractures, are a significant concern in the aging population, with increasing incidence rates. Valgus-impacted fractures pose unique challenges due to their complex malalignments, which can lead to complications such as avascular necrosis and impaired mobility.

Key Findings
The RA group required longer operative times compared to the IF group (1.74 vs. 1.29 hours).
Significantly fewer fluoroscopy sessions were needed in the RA group (33.28 vs. 56.56).
Guide-pin adjustments were markedly lower in the RA group (0.17 vs. 1.89).
Femoral neck shortening was significantly less in the RA group (2.5 mm vs. 9.1 mm).
The RA group achieved higher Harris Hip Scores (82.00 vs. 73.61).
Lower incidences of femoral head necrosis, non-union, and fixation failure were observed in the RA group.
Clinical Implications
The integration of manual reverse reduction with robotic assistance may enhance surgical precision and reduce complications in elderly patients with valgus-impacted femoral neck fractures.
Conclusion
Combining manual reverse reduction with robotic-assisted fixation shows potential in improving surgical outcomes for osteoporotic femoral neck fractures in the elderly.
