Efficacy of naproxen prophylaxis for the prevention of heterotopic ossification after hip surgery: a meta-analysis.

BACKGROUND: This meta-analysis aimed to assess whether the specific nonsteroidal anti-inflammatory drug (NSAID) naproxen has a role in reducing the occurrence of heterotopic ossification after hip surgery. METHODS: Potential studies were identified in the following electronic databases: PubMed, EMBASE, Web of Science, Cochrane Library, and Google. We included studies involving hip surgery patients in which the intervention group received naproxen and the control group received placebo. The occurrence of heterotopic ossification and complications were the final outcomes. Stata 13.0 was used for the meta-analysis. RESULTS: Four randomized controlled trials (RCTs) involving 269 patients were ultimately included in this meta-analysis. The use of naproxen was associated with a significant reduction in the occurrence of heterotopic ossification at 1.5-, 3-, 6-, and 12-month follow-ups (P < 0.05). There was no significant difference in the occurrence of complications between treatment and control groups (P > 0.05). CONCLUSION: Our analysis indicates that naproxen can decrease the occurrence of heterotopic ossification without increasing complications in hip surgery patients. Due to the limited number of studies included, more high-quality RCTs are needed to identify the optimal dose of naproxen.

Topical use of topical fibrin sealant can reduce the need for transfusion, total blood loss and the volume of drainage in total knee and hip arthroplasty: A systematic review and meta-analysis of 1489 patients.

OBJECTIVE: To evaluate the efficacy and safety of fibrin sealant for the reduction of postoperative blood loss and transfusion requirements in patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA). METHODS: Electronic databases including PubMed, Embase, CENTRAL (Cochrane Controlled Trials Register), Web of Science and Google Scholar were searched from database inception to February 2016. All randomized controlled trials evaluating the efficacy and safety of topical administration of fibrin glue during primary THA or TKA were included in our meta-analysis. Transfusion requirements, total blood loss, length of hospital stay and the occurrence of infection were calculated using Stata 12.0 software. RESULTS: A total of nineteen clinical trials with 1489 patients (405 hips and 1084 knees) were finally included for meta-analysis. The results indicated that the topical administration of fibrin sealant can decrease the need for transfusion (RR = 0.33, 95%CI 0.28-0.40, P < 0.001), total blood loss (MD = -138.25, 95% CI -203.49 to -75.00), blood loss in drainage (MD -321.44, 95% CI -351.96 to -290.92, P < 0.001) and hospital stay length (MD -0.98, 95% CI -1.35 to -0.62, P < 0.001) without increasing the occurrence of infection (RR = 0.87, 95% CI 0.33 to 2.27, P = 0.775). CONCLUSION: The topical use of fibrin sealant can effectively reduce the need for transfusion, total blood loss and the volume of drainage without increasing the rate of infection.
