Comparison of integrated dual-lag screw versus single lag screw cephalomedullary nails for intertrochanteric femoral fractures: a systematic review and meta-analysis.

ABSTRACT:

Background

To determine whether an integrated dual-lag-screw (IDLS) cephalomedullary nail (CMN) confers superior clinical and mechanical outcomes compared with single-lag-screw (SLS) designs in the fixation of intertrochanteric femoral fractures.

Methods

Seven databases (MEDLINE, Embase, Cochrane CENTRAL, Web of Science, Google Scholar, ClinicalTrials.gov) were searched from inception through 20 January 2025 following PRISMA guidelines. Randomized trials and comparative observational studies of adult intertrochanteric or subtrochanteric extension fractures treated with IDLS versus SLS nailing and ≥ 6 months follow-up were eligible. Twenty-nine studies met all criteria. Three reviewers independently screened studies, extracted data, and graded quality (ROB-2 for randomized co
