Background To date, there are just several studies comparing distal locked nails with distal unlocked nails in treating intertrochanteric fractures. We report the first meta‐analysis about this issue. Methods Systematic search was conducted for studies in PubMed, Embase and Cochrane Library. Meta‐analyses were performed regarding intra operative outcomes, complications and functional outcomes. Results Pooled results showed insignificant difference between distal locking group and distal unlocking group in hip pain (relative risk (RR) 1.14, 95% confidence interval (CI) 0.59–2.19), distal tip fracture (RR 1.08, 95% CI 0.37–3.11), lag screw cut‐out (RR 1.60, 95% CI 0.54–4.78), delayed or nonunion (RR 1.32, 95% CI 0.25–7.06), deep vein thrombosis (RR 1.06, 95% CI 0.23–4.84), wound infection (RR 0.58, 95% CI 0.28–1.22), Harris hip score (standard mean deviation (SMD) 0.03, 95% CI −0.15 to 0.21) and walking ability. However, significant difference was detected in operation time (SMD 0.77, 95% CI 0.36–1.17), fluoroscopy exposure time (SMD 1.02, 95% CI 0.52–1.52), blood loss (SMD 0.80, 95% CI 0.62–0.99) and total incision length (SMD 1.16, 95% CI 0.86–1.47). Result of trial sequential analysis indicated conclusive evidence. Conclusion Current evidence indicates that the distal locked intramedullary nails should not be recommended as routine choice for stable intertrochanteric fractures.
