Abstract
Background: Long bone fractures, especially in the lower limbs, are highly prevalent in orthopedic practice. These fractures can significantly impair patients' mobility and quality of life. Intramedullary nails are a mainstay treatment, offering reliable fracture fixation. However, the addition of blocking screws has introduced an element of uncertainty regarding surgical outcomes. This meta-analysis evaluated the efficacy and complications of blocking screw fixation for lower limb long bone fractures (LLLBF).
Methods: A comprehensive and systematic search was conducted across eight databases, namely the Cochrane Library, PubMed, EMbase, Web of Science, CNKI, China Biomedical Literature Database (CBM), VIP, and WanFang, to identify relevant controlled trials. Before data analysis, the quality of each study was rigorously assessed. Subsequently, the data were analyzed using the Review Manager 5.3 (RevMan 5.3) software to ensure a reliable and accurate synthesis of the evidence.
Results: A total of 15 studies were incorporated into the analysis. Compared with the control group, the experimental group demonstrated a significantly shorter fracture healing time (standardized mean difference, SMD = -2.18; 95% confidence interval, CI: -3.17 to -1.20; P < 0.001), suggesting a substantial effect in favor of the intervention. Additionally, the experimental group had a longer operation time (SMD = 15.81, 95% CI: 4.28, 27.34, P = 0.007), less intraoperative bleeding (SMD = -75.60, 95% CI: -127.93, -23.27, P = 0.005), and fewer complications (odds ratio, OR = 0.51, 95% CI: 0.31, 0.84, P = 0.008). However, no significant difference was observed in the fracture healing rates between the two groups (OR = 1.09, 95% CI: 0.98, 1.20, P = 0.098).
Conclusion: The findings of this study suggest that the use of intramedullary nails in conjunction with blocking screws could potentially be an effective treatment option for patients with lower limb long bone fractures. However, to confirm this efficacy, additional high - quality research, preferably well-designed randomized controlled trials with large sample sizes and long-term follow - up, is warranted.
期刊介绍:
Evidence of surgical interventions go back to prehistoric times. Since then, the field of surgery has developed into a complex array of specialties and procedures, particularly with the advent of microsurgery, lasers and minimally invasive techniques. The advanced skills now required from surgeons has led to ever increasing specialization, though these still share important fundamental principles.
Frontiers in Surgery is the umbrella journal representing the publication interests of all surgical specialties. It is divided into several “Specialty Sections” listed below. All these sections have their own Specialty Chief Editor, Editorial Board and homepage, but all articles carry the citation Frontiers in Surgery.
Frontiers in Surgery calls upon medical professionals and scientists from all surgical specialties to publish their experimental and clinical studies in this journal. By assembling all surgical specialties, which nonetheless retain their independence, under the common umbrella of Frontiers in Surgery, a powerful publication venue is created. Since there is often overlap and common ground between the different surgical specialties, assembly of all surgical disciplines into a single journal will foster a collaborative dialogue amongst the surgical community. This means that publications, which are also of interest to other surgical specialties, will reach a wider audience and have greater impact.
The aim of this multidisciplinary journal is to create a discussion and knowledge platform of advances and research findings in surgical practice today to continuously improve clinical management of patients and foster innovation in this field.
