Cannulated screws versus dynamic hip screw versus hemiarthroplasty versus total hip arthroplasty in patients with displaced and non-displaced femoral neck fractures: a systematic review and frequentist network meta-analysis of 5703 patients.
Our aim was to determine the best operative procedure in human participants with a displaced or non-displaced femoral neck fracture comparing cannulated screw (CS) fixation, dynamic hip screw (DHS) fixation, hemiarthroplasty (HA), and total hip arthroplasty (THA) in terms of surgical and functional outcomes, reoperation and postoperative complications.
We searched PubMed, The Cochrane Library, Clinical trials, CINAHL, and Embase for randomized controlled trials (RCTs) or quasi-RCTs up to 31 July 2022. A frequentist network meta-analysis was performed to assess the comparative effects of the four operative procedures, using fixed-effects and random-effects models. Mean differences (MDs) with 95% confidence intervals (CIs) were estimated for continuous variables and odds ratios (ORs) with 95% CIs were estimated for binary variables.
A total of 33 RCTs with 5703 patients were included in our network meta-analysis. CS fixation was best in terms of operation time (CS: MD = - 57.70, 95% CI - 72.78; - 42.62; DHS: MD = - 53.56, 95% CI - 76.17; - 30.95; HA: MD = - 20.90, 95% CI - 30.65; - 11.15; THA: MD = 1.00 reference) and intraoperative blood loss (CS: MD = - 3.67, 95% CI - 4.44; - 2.90; DHS: MD = - 3.20, 95% CI - 4.97; - 1.43; HA: MD = - 1.20, 95% CI - 1.73; - 0.67; THA: MD = 1.00 reference). In life quality and functional outcome, measured at different time points with EQ-5D and the Harris Hip Score (HHS), THA ranked first and HA second (e.g. EQ-5D 2 years postoperatively: CS: MD = - 0.20, 95% CI - 0.29; - 0.11; HA: MD = - 0.09, 95% CI - 0.17; - 0.02; THA: MD = 1.00 reference; HHS 2 years postoperatively: CS: MD = - 5.50, 95% CI - 9.98; - 1.03; DHS: MD = - 8.93, 95% CI - 15.08; - 2.78; HA: MD = - 3.65, 95% CI - 6.74; - 0.57; THA: MD = 1.00 reference). CS fixation had the highest reoperation risk, followed by DHS fixation, HA, and THA (CS: OR = 9.98, 95% CI 4.60; 21.63; DHS: OR = 5.07, 95% CI 2.15; 11.96; HA: OR = 1.60, 95% CI 0.89; 2.89; THA: OR = 1.00 reference).
In our cohort of patients with displaced and non-displaced femoral neck fractures, HHS, EQ-5D, and reoperation risk showed an advantage of THA and HA compared with CS and DHS fixation. Based on these findings, we recommend that hip arthroplasty should be preferred and internal fixation of femoral neck fractures should only be considered in individual cases.

Total Hip Arthroplasty Leads to Better Results After Low-Energy Displaced Femoral Neck Fracture in Patients Aged 55 to 70 Years: A Randomized Controlled Multicenter Trial Comparing Internal Fixation and Total Hip Arthroplasty.
The optimal treatment of displaced femoral neck fractures in patients 55 to 70 years old remains controversial. The aim of the present study was to assess the effect of closed reduction and internal fixation with cannulated screws (IF) compared with total hip arthroplasty (THA) on hip pain and function, with use of data for outcome measures, complications, and reoperations.
This multicenter randomized controlled trial included all patients 55 to 70 years old who presented with a low-energy displaced femoral neck fracture between December 2013 and December 2018. Patients were randomly allocated to undergo either IF or THA. The primary outcome was the Harris Hip Score (HHS) at 12 months postoperatively. Secondary outcomes were the HHS at 4 and 24 months postoperatively, Oxford Hip Score (OHS), Hip Disability and Osteoarthritis Outcome Score (HOOS), health-related quality of life (EQ-5D-3L [EuroQol 5 Dimensions 3 Levels] index score and EQ-VAS [visual analogue scale]), VAS for pain, and VAS for patient satisfaction at 4, 12, and 24 months postoperatively. Complications and reoperations were continuously monitored. The primary analyses were performed according to the intention-to-treat principle.
A total of 102 patients with a mean (± standard deviation) age of 63.7 ± 4.2 years were allocated to IF (n = 51) or THA (n = 51). The mean difference in the primary outcome, the HHS at 12 months postoperatively (5.3; 95% confidence interval, 0.9 to 9.7; p = 0.017), was below the predefined minimal clinically important difference of 10 points. However, patients who underwent THA had a significantly higher HHS at 4 and 12 months, better OHS at 4 and 12 months, and better HOOS at 4, 12, and 24 months postoperatively. Patients who underwent THA also reported better health-related quality of life at 4 months postoperatively and reported greater satisfaction and less pain at 4 and 12 months postoperatively. A total of 26 patients in the IF group (51%; 95% confidence interval, 37% to 65%) and 2 patients in the THA group (4%; 95% confidence interval, 0.5% to 13%) underwent a major reoperation.
In this randomized controlled trial, we showed that patients between 55 and 70 years old who underwent THA for a low-energy displaced femoral neck fracture experienced better outcomes than those who underwent closed reduction and internal fixation.
