Background: The aim of the study was to compare the short-term outcome of SuperPATH, direct anterior (DAA) and conventional approach (CA) hemiarthroplasty (HA) in patients with femoral neck fractures using a network meta-analysis., Methods: PubMed, China National Knowledge Infrastructure, Epistemonikos, and Embase were searched until May 31, 2024. In a network meta-analysis, mean differences with 95% confidence intervals were calculated using the Hartung-Knapp-Sidik-Jonkman method and a fixed/random effects model for continuous outcomes, and odds ratios with 95% confidence intervals were calculated using the Mantel-Haenszel method and a fixed/random effects model for dichotomous outcomes., Results: The literature search identified a total of 9 randomized controlled trials on SuperPATH with 762 patients and 8 randomized controlled trials on DAA with 641 patients. In the overall ranking, SuperPATH was placed first, DAA second and CA third. SuperPATH HA was best in 7, second best in 2 and third best in 1 of the 10 outcome parameters. DAA HA was best in 2 and second best in 8 of the 10 outcome parameters. CA HA was best in 1 and third best in 9 of the 10 outcome parameters. In the indirect comparison between SuperPATH HA and DAA HA, SuperPATH HA had a 1.36 point lower visual analog scale at 2 to 7 days postoperatively and a 0.17 lower overall complication rate compared to DAA., Conclusion: For the treatment of patients with femoral neck fractures, SuperPATH HA ranked first, DAA HA ranked second and CA HA ranked third. Based on the results, we recommend that trauma surgeons increase their use of minimally invasive hip HA techniques. It should be noted that SuperPATH HA had a significantly lower overall complication rate compared to DAA HA when the minimally invasive technique was chosen., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

The aim was to conduct a systematic review of literature and meta-analysis of randomized controlled trials (RCTs) comparing short-term outcomes of bipolar hemiarthroplasty (HA) through SuperPATH and bipolar HA through conventional approaches (CAs) in patients with femoral neck fractures. The following PICO question was formulated: In human participants with femoral neck fractures, are the short-term outcomes of SuperPATH HA better than the short-term outcomes of CAs HA? The following databases were searched until 25 August 2023: PubMed, CNKI, CENTRAL of The Cochrane Library, Clinical trials, and Google Scholar. Quality assessment of the RCTs was performed, according to the Cochrane's Risk of Bias 2 tool and the recommendations of the GRADE system. Furthermore, we evaluated publication bias with funnel plots. Mean differences (MDs) with 95% confidence intervals (CIs) were calculated for continuous variables using the Hartung-Knapp-Sidik-Jonkman method and a random effects model. Nine RCTs with overall 762 patients were included in this meta-analysis. All 9 RCTs were rated with a moderate risk of bias. The quality of evidence of the outcome parameters was rated moderate to very low. The funnel plots were overall broadly symmetrical, possibly indicating low to moderate publication bias. SuperPATH had a longer operation time compared to CAs (MD = 21.79, 95% CI 12.57 to 31.02). SuperPATH decreased incision length (MD = - 4.50; 95% CI - 5.80 to - 3.20), intraoperative blood loss (MD = - 103.96, 95% CI - 150.27 to - 55.66), postoperative drainage volume (MD = - 137.30, 95% CI - 178.74 to - 95.86), time to mobilization (MD = - 3.86; 95% CI - 5.96 to - 1.76), pain VAS ≤ 1 week postoperatively (MD = - 1.81; 95% CI - 2.17 to - 1.45), and hospitalization time (MD = - 4.05; 95% CI - 4.96 to - 3.15). SuperPATH improved HHS ≤ 1 week postoperatively (MD = 11.10; 95% CI 1.65 to 20.54) and HHS 3 months postoperatively (MD = 6.33; 95% CI 3.97 to 8.69). There was no difference in pain VAS 1-3 months postoperatively (MD = - 0.08; 95% CI - 0.22 to 0.05) and HHS 6 months postoperatively (MD = 0.44; 95% CI - 0.11 to 1.00). This is the first meta-analysis comparing SuperPATH HA with CAs HA in patients with femoral neck fractures. SuperPATH HA was superior in the early short-term functional outcome (HHS) compared to CAs HA, reaching minimal clinically important differences. Furthermore, SuperPATH HA showed significantly better results in incision length, blood loss, time to mobilization, pain intensity (VAS), and hospitalization time than CAs HA., (© 2023.
