Meta-Analysis
PURPOSE
The objective of this systematic review and meta-analysis was to assess the efficacy of the Ilizarov method in the treatment of radius and ulna bone defects.
METHODS
The PubMed, Embase, Web of Science, Cochrane Library, Ovid MEDLINE, and Scopus databases were searched for articles published up to May 2023. The quality of the studies was evaluated using a modified version of the Newcastle-Ottawa scale. The effect size and confidence intervals at 95% for the main results were calculated. The heterogeneity was evaluated. The demographic data, defect size (DS), external fixation time (EFT), external fixation index (EFI), and complications were extracted and analyzed using the Stata version 16.
RESULTS
This meta-analysis identified and included seven studies involving 98 patients. The union rate of 100% was reported in all studies. According to the findings of the single-arm meta-analysis, the pooled DS was 3.42 cm (95% CI [2.64, 4.21], I = 53.5%, P = 0.045), EFT was 148.43 days (95% CI [97.49, 199.38], I = 91.9%, P = 0.000), and EFI was 41.32 days/cm (95% CI [35.72, 46.91], I = 62.2%, P = 0.021). Pin tract infection was the most common complication, as reported in six studies.
CONCLUSION
The findings of the present meta-analysis indicate that the Ilizarov technique is a successful treatment option for bone defects in the radius and ulna. This method has demonstrated efficacy in achieving expected clinical outcomes.

Meta-Analysis
BACKGROUND
Internal fixation with cephalomedullary nails has been widely used in the treatment of intertrochanteric femoral fractures (IFF). Yet, the difference in efficacy and safety between the commonly used integrated dual-screw cephalomedullary nail (InterTAN) and single-screw cephalomedullary nail remains inconclusive. Thus we performed the present systematic review and meta-analysis.
METHODS
Randomized controlled trials (RCTs) or observational studies comparing InterTAN with proximal femoral nail anti-rotation (PFNA), the Asian PFNA (PFNA-II), or the Gamma3 nail in treating IFF were searched on PubMed, EMBASE, Web of Science and Cochrane Library from inception to April 30, 2023. The differences in perioperative parameters and clinical and radiological outcomes were evaluated by mean difference (MD) with 95% confidence interval (95%CI). The risks of various complications and mortality were assessed by risk ratio (RR) with 95%CI.
RESULTS
Twenty-three studies comprising 3566 patients were included. Compared with single-screw cephalomedullary nails (PFNA/PFNA-II, Gamma3), InterTAN conferred significantly reduced risk of implant failures (RR = 0.37, 95%CI 0.26 to 0.51, P < 0.001), hip and thigh pain (RR = 0.70, 95%CI 0.55 to 0.90, P = 0.006) and all-cause revision/reoperation (RR = 0.38, 95%CI 0.26 to 0.57, P < 0.001). Moreover, patients treated with InterTAN had significantly higher 1-year Harris Hip Score (MD = 0.82, 95%CI 0.20-1.44, P = 0.010) and shorter time to union/healing (MD = - 0.66 days, 95%CI - 1.16 to - 0.16, P = 0.009). Femoral neck shortening, time to full bearing, and incidences of non-union, infection, deep venous thrombosis, and mortality were comparable between both groups.
CONCLUSIONS
The integrated dual-screw InterTAN construct has superior performance in reducing risks of complications and improving clinical and functional outcomes in the treatment of IFF. More well-designed, high-quality RCTs are warranted to confirm these findings.

Review
Nonunion (NU) is one of the most feared complications of femoral shaft fracture treatment. Femoral shaft fracture treatment is often linked with poor bone stock and reduced bone metabolism. In this paper, the goal is to carefully analyze the best treatment options for patients who developed nonunion after the intramedullary nailing of a femoral shaft fracture. A systematic review of the literature available in the PubMed, EMBASE and Cochran library databases was carried out, and 16 studies were included. Exclusion criteria included case reports and case series that do not have data about clinical outcomes or functional outcomes and included fewer than 10 patients. The reviewed data provide evidence for very good results about the treatment of this pathology with exchanging intramedullary nails or the implantation of a plate and screws (general healing rate of 96.3%). Moreover, the data support the utilization of autologous bone graft in order to stimulate the healing process. In conclusion, the choice between these two types of treatment must be guided by the type of pseudarthrosis that the patient presents. Additionally, bone grafting or growth factors promote bone regenerative processes, especially in patients with oligo-atrophic pseudoarthrosis.

Meta-Analysis
AIM
Tibial shaft fractures are the most common type of long-bone fractures. External fixation (EF) and intramedullary nailing (IMN) are widely used surgical techniques for the definitive fixation of open tibial shaft fractures. The aim of this systematic review and meta-analysis was to compare EF to IMN for the definitive fixation of open tibial fractures.
METHODS
Medline, Embase, and CENTRAL databases were searched for eligible studies. We included randomized controlled trials (RCTs) that compared EF to IMN for skeletally mature adults with open tibial fracture (Gustilo I, II, and III). We evaluated the following outcomes: superficial infection, pin-track infection, deep infection, malunion, nonunion, delayed union, and implant/hardware failure. The risk ratio (RR) was used to represent the desired outcomes. The statistical analysis was performed using the random-effects model.
RESULTS
A total of 12 RCTs that enrolled 1090 participants were deemed eligible for the analysis. EF showed a significantly higher rate of superficial infection, pin track infection, and malunion compared to IMN (RR = 2.30, 95% confidence interval (CI): 1.34 to 3.95; RR = 13.52, 95% CI: 6.16 to 29.66; RR = 2.29, 95% CI 1.41 to 3.73, respectively). No substantial difference was found between EF and IMN in terms of deep infection, nonunion, delayed union, or implant/hardware failure (RR = 1.15, 95% CI 0.67 to 1.98; RR = 0.92, 95% CI 0.77 to 1.10; RR = 1.50, 95% CI 0.98 to 3.33; RR = 0.96, 95% CI 0.36 to 2.60, respectively).
DISCUSSION
The findings of our meta-analysis are consistent with the previous systematic reviews excepts for the implant/hardware failure which was found to be significant in favour of IMN by one of the previous reviews.
CONCLUSION
This meta-analysis confirms that IMN is better than EF with respect to clinical outcomes and complication rate for the definitive fixation of open tibial fracture.

INTRODUCTION
Fractures of the proximal femur accompanied by a fracture of the femoral shaft are relatively rare, with a reported prevalence between 1 and 12%. Multiple surgical options are available, consisting of treatment with a single implant or with double implants. Controversy exists about the optimal management. A systematic review and pooled analysis were performed to assess the most reliable treatment for bifocal femoral fractures of the femur.
MATERIALS AND METHODS
A literature search was conducted on July 15, 2022. Selected studies were screened on title and abstract by two researchers independently, and full texts were read by both authors. Emphasis was put on adverse events such as postoperative infection, healing complications, malalignment, and functional outcome using either a single implant or double implants.
RESULTS
For the proximal femoral fractures, no significant difference could be confirmed for avascular necrosis of the femoral neck (5.1% for single implant and 3.8% for double implants), nonunion (6.4% for single implant and 7.8% for double implants), or varus malalignment (6.6% for single implant and 10.9% for double implants). This study also suggests that the number of implants is irrelevant for complications of the femoral shaft regarding the rates of postoperative infection and healing complications. Pooled rates of bone healing complications were 1.6-2.7-fold higher when patients were treated with a single implant, but statistical significance could not be confirmed. For hardware failure, revision surgery, leg length discrepancy, and functional outcome, no difference between the two groups was found either.
CONCLUSIONS
The pooled proportions of all postoperative complications had overlapping confidence intervals; thus, no inference about a statistically significant difference on the number of implants used for treating ipsilateral fractures of the femur can be made. Both treatment groups showed a similar functional outcome at the last moment of follow-up, with more than 75% of the patients reporting a good outcome.

INTRODUCTION
Nonunion of long bones is a major complication following fractures that requires a substantial amount of investment both monetary and time from patients and surgeons. The need to comprehensively understand the complications, outcomes and distraction capability is profound, which necessitates a review of current evidence on special fixators used for distraction. The current systematic review aims to study the available literature on distraction osteogenesis using special fixators (Ilizarov and Limb Reconstruction System) in the management of nonunion (infected and non-infected).
METHODS
Cochrane Library, PubMed, Scopus were searched until January 2022. The review included all original studies which used Ilizarov or Monorail Fixators/LRS in the treatment of nonunion of long bones. The quality of studies was assessed using the Modified Coleman Methodology Score.
RESULTS
A total of 35 original studies with Ilizarov (n = 29) and LRS (n = 8) were selected including two comparative studies. The pooled data meta-analysis and the subgroup analysis of these studies found both Ilizarov and LRS fixator yield similar functional outcomes for the treatment of long bones nonunion.
CONCLUSION
The review was conducted to understand the scenario of nonunion in long bones. Pin tract infection is found to be the most common complication followed by adjacent joint stiffness and deformity. In our review we observed that both external fixator time and index were lower in LRS compared to Ilizarov group. Further RCT are required comparing Ilizarov and LRS fixators to effectively comment upon the superiority of the implants.

PURPOSE
Ototoxicity is one of the major adverse effects of cisplatin therapy which restrict its clinical application. Alpha-lipoic acid administration may mitigate cisplatin-induced ototoxicity. In the present study, we reviewed the protective potentials of alpha-lipoic acid against the cisplatin-mediated ototoxic adverse effects.
METHODS
Based on the PRISMA guideline, we performed a systematic search for the identification of all relevant studies in various electronic databases up to June 2022. According to the inclusion and exclusion criteria, the obtained articles (n=59) were screened and 13 eligible articles were finally included in the present study.
RESULTS
The findings of in-vitro experiments showed that cisplatin treatment significantly reduced the auditory cell viability in comparison with the control group; nevertheless, the alpha-lipoic acid co-administration protected the cells against the reduction of cell viability induced by cisplatin treatment. Moreover, the in-vivo results of the auditory brainstem response (ABR) and distortion product otoacoustic emission (DPOAE) tests revealed a decrease in DPOAE and an increase in ABR threshold of cisplatin-injected animals; however, it was shown that alpha-lipoic acid co-treatment had an opposite pattern on the evaluated parameters. Other findings demonstrated that cisplatin treatment could significantly induce the biochemical and histopathological alterations in inner ear cells/tissue; in contrast, alpha-lipoic acid co-treatment ameliorated the cisplatin-mediated biochemical and histological changes.
CONCLUSION
The findings of audiometry, biochemical parameters, and histological evaluation showed that alpha-lipoic acid co-administration alleviates the cisplatin-induced ototoxicity. The protective role of alpha-lipoic acid against the cisplatin-induced ototoxicity can be due to different mechanisms of anti-oxidant, anti-apoptotic, anti-inflammatory activities, and regulation of cell cycle progression.

BACKGROUND
Although chemotherapy and radiotherapy are effective in cancer treatment, different adverse effects induced by these therapeutic modalities (such as ototoxicity) restrict their clinical use. Co-treatment of melatonin may alleviate the chemotherapy/radiotherapy-induced ototoxicity.
OBJECTIVE
In the present study, the otoprotective potentials of melatonin against the ototoxicity induced by chemotherapy and radiotherapy were reviewed.
METHODS
According to the PRISMA guideline, a systematic search was carried out to identify all relevant studies on "the role of melatonin against ototoxic damage associated with chemotherapy and radiotherapy" in the different electronic databases up to September 2022. Sixty-seven articles were screened based on a predefined set of inclusion and exclusion criteria. Seven eligible studies were finally included in this review.
RESULTS
The in vitro findings showed that cisplatin chemotherapy significantly decreased the auditory cell viability compared to the control group; in contrast, the melatonin co-administration increased the cell viability of cisplatin-treated cells. The results obtained from the distortion product otoacoustic emission (DPOAE) and auditory brainstem response (ABR) tests demonstrated a decreased amplitude of DPOAE and increased values of ABR I-IV interval and ABR threshold in mice/rats receiving radiotherapy and cisplatin; nevertheless, melatonin co-treatment indicated an opposite pattern on these evaluated parameters. It was also found that cisplatin and radiotherapy could significantly induce the histological and biochemical changes in the auditory cells/tissue. However, melatonin co-treatment resulted in alleviating the cisplatin/radiotherapy-induced biochemical and histological changes.
CONCLUSION
According to the findings, it was shown that melatonin co-treatment alleviates the ototoxic damage induced by chemotherapy and radiotherapy. Mechanically, melatonin may exert its otoprotective effects via its anti-oxidant, anti-apoptotic, and anti-inflammatory activities and other mechanisms.

Meta-Analysis Review
OBJECTIVE
This systematic review and meta-analysis compared extramedullary fixation and intramedullary fixation for stable two-part trochanteric femoral fractures (AO type 31-A1) with regards to functional outcomes, complications, and surgical outcomes.
METHODS
Embase, Medline, Web of Science, Cochrane Central Register of Controlled Trials, and Google Scholar were searched for randomized controlled trials (RCTs) and observational studies. Effect estimates were pooled across studies using random effects models. Results were presented as weighted risk ratio (RR) or weighted mean difference (MD) with corresponding 95% confidence interval (95% CI).
RESULTS
Five RCTs (397 patients) and 14 observational studies (21,396 patients) were included. No significant differences in functional outcomes, complications, or surgical outcomes were found between extramedullary and intramedullary fixation devices, except for a difference in duration of surgery (MD 14.1 min, CI 5.76-22.33, p < 0.001) and intra-operative blood loss (MD 92.30 mL, CI 13.49-171.12, p = 0.02), favoring intramedullary fixation.
CONCLUSION
Current literature shows no meaningful differences in complications, surgical, or functional outcomes between extramedullary and intramedullary fixation of stable two-part trochanteric femoral fractures. Both treatment options result in good outcomes. This study implicates that, costs should be taken into account when considering implants or comparing fixation methods in future research.
