Meta-Analysis
OBJECTIVES
The objective of this Health Technology Assessment was to evaluate effectiveness, complications and cost-effectiveness of surgical or non-surgical treatment for proximal, diaphyseal or distal fractures of the humerus in elderly patients. Secondary objectives were to evaluate the intervention costs per treatment of proximal humerus fractures (PHF) and to investigate treatment traditions of PHF in Sweden.
METHODS AND FINDINGS
The assessment contains a systematic review of clinical and health economic studies comparing treatment options for humerus fractures in elderly patients. The results regarding the effectiveness of treatments are summarized in meta-analyses. The assessment also includes a cost analysis for treatment options and an analysis of registry data of PHF. For hemiarthroplasty (HA) and non-operative treatment, there was no clinically important difference for moderately displaced PHF at one-year follow-up regarding patient rated outcomes, (standardized mean difference [SMD]) -0.17 (95% CI: -0.56; 0.23). The intervention cost for HA was at least USD 5500 higher than non-surgical treatment. The trend in Sweden is that surgical treatment of PHF is increasing. When functional outcome of percutaneous fixation/plate fixation/prosthesis surgery and non-surgical treatment was compared for PHF there were no clinically relevant differences, SMD -0.05 (95% CI: -0.26; 0.15). There was not enough data for interpretation of quality of life or complications. Evidence was scarce regarding comparisons of different surgical options for humerus fracture treatment. The cost of plate fixation of a PHF was at least USD 3900 higher than non-surgical treatment, costs for complications excluded. In Sweden the incidence of plate fixation of PHF increased between 2005 and 2011.
CONCLUSIONS
There is moderate/low certainty of evidence that surgical treatment of moderately displaced PHF in elderly patients has not been proven to be superior to less costly non-surgical treatment options. Further research of humerus fractures is likely to have an important impact.

Review
BACKGROUND
This is the first systematic review of the relationship between humeral shaft fractures and radial nerve palsy in children. The present comprehensive review is aimed at identifying important clinical findings between humeral diaphysis fractures and radial nerve injuries and assessing the effects of treatment.
METHODS
We searched electronic bibliographic databases, including PubMed, the Cochrane Library, Scopus, and Web of Knowledge, until March 2022. This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the patients, interventions, comparisons, outcomes guidelines.
RESULTS
We identified 23 original papers, of which 10 were eligible for further analysis. Cases of 32 young patients with radial nerve palsy were identified and analyzed. The prevalence of radial nerve palsy was 4.34% (eight cases out of 184 patients with humeral shaft fractures). The radial nerve was most often associated with a simple transverse fracture (12A3, 17 cases (65.4%)).
CONCLUSIONS
Radial nerve injury in humeral shaft fractures in children is rare, with a frequency of 4.34%. We highly recommend early surgical nerve exploration with transverse fractures in the distal third segment combined with primary radial palsy. Furthermore, we recommend making thoughtful decisions regarding early nerve exploration in the Holstein-Lewis fractures. In addition, consideration of early surgical nerve exploration in fractures resulting from high-energy trauma and open fractures despite their morphology is recommended.

Review
BACKGROUND
The two techniques most utilized in the surgical treatment of humeral shaft fractures are open reduction internal fixation (ORIF) and intramedullary nailing (IMN). Although there have been multiple comparative clinical studies comparing outcomes for these two treatments, studies have not suggested one approach to be superior to the other. The purpose of this study is to perform a systematic literature review and meta-analysis of studies that evaluated the treatment of humeral shaft fractures with either ORIF or intramedullary nail.
METHODS
We conducted this meta-analysis utilizing stricter inclusion and broader exclusion criteria to examine these two common approaches. We examined those articles which have compared first-time, closed fractures of the humeral diaphysis in adults in fracture patterns that could be treated equivalently by intramedullary nail or plate fixation. The primary outcome of interest was nonunion, and studies that did not report nonunion rates were excluded.
RESULTS
There were a total of 1,926 abstracts reviewed and a total of three articles were included in the final analysis after screening. There was no significant difference in the incidence of nonunion between plating (2/111, 1.8%) and nailing (4/104, 3.9%) (). The mean difference in average time to union for plated fractures and nailed fractures was 1.11 weeks (95% CI 0.82 to 1.40) which was statistically significant (). There was a significant difference in the incidence of radial nerve palsy (12/111, 10.8%) for plating compared to nailing (0/104, 0%) (). There was no difference in incidence of post-operative infection between the two groups intramedullary nailing ().
CONCLUSION
The results of this analysis demonstrate an increased risk of iatrogenic radial nerve injury, and a significantly shorter time to union when treating humeral shaft fractures with plating as compared to intramedullary nailing. There was no difference in the rates of nonunion or delayed union. Based on the evidence, both plating and nailing can achieve a similar treatment effect on humeral shaft fractures.

Review
(1) Background: Avascular necrosis (AVN) may affect every part of the bone. Epiphyseal infarcts are likely to be treated early because most are symptomatic. However, meta- and diaphyseal infarcts are silent and are diagnosed incidentally. Sarcomas developing in the necrotic bone are extremely rare, but they have been reported in the literature. (2) Methods: We conducted a mapping review of recent evidence regarding these malignancies. Methods: A mapping review using a systematic search strategy was conducted to answer research questions. We limited our research to the last ten years (2012-2022). (3) Results: A total of 11 papers were identified, including 9 case reports and 3 case series. The pathomechanism of carcinogenesis in AVN was not investigated to date. Histologically, most tumors were malignant fibrous histiocytoma. The prognosis is relatively poor, especially for patients with metastases, but adjuvant chemotherapy may increase short- and long-term survival. (4) Conclusions: Since AVN-related malignancies are sporadic, no prospective studies have been conducted. The majority of evidence comes from small case series. More research is needed to identify the risk factors that would justify follow-up of patients after bone infarcts at higher risk of developing a malignancy.

Meta-Analysis Review
PURPOSE
Early weight bearing (EWB) is often recommended after intramedullary nailing of tibial shaft fractures, however, the risks and benefits have not been critically evaluated in a systematic review or meta-analysis. Therefore, the aims of this study were to perform a systematic review and meta-analysis comparing EWB and delayed weight-bearing (DWB) after intramedullary nailing of tibial shaft fractures and assess the relationship between weight-bearing, fracture union and healing.
METHOD
This review included studies comparing the effects of EWB, defined as weight-bearing before 6 weeks, and DWB on fracture union and healing. PubMed, Embase, CINAHL, and the Cochrane Library were searched from inception to 9 May 2021. Risk of bias was assessed using the Down's and Black Checklist and Cochrane Risk of Bias Tool 2.0. Data were synthesised in a meta-analysis, as well as narrative and tabular synthesis.
RESULTS
Eight studies were included for data extraction and meta-analysis. The analysis produced mixed results and found a significant decrease in mean union time (-2.41 weeks, 95% confidence interval: -4.77, -0.05) with EWB and a significant Odd's Ratio (OR) for complications with DWB (OR: 2.93, 95% CI: 1.40, 6.16). There was no significant difference in rates of delayed union, non-union, re-operation and malunion.
CONCLUSION
The included studies were of moderate risk of bias and demonstrated shorter union time and fewer complications with EWB. However, current evidence is minimal and has significant limitations. The role of EWB in high-risk patients is yet to be examined. Further well-designed, randomised studies are required on the topic.

Review
BACKGROUND
Atypical femoral fractures are the femoral fractures located anywhere between the lesser trochanter and the supracondylar flare of the femur. Long-term bisphosphonates, as the most common preventive and treatment medications for osteoporosis, are thought to have an important role in these fractures. Most of the fractures should be treated surgically, and the complications are considerable.
METHODS
We searched Medline, CENTRAL, Embase, and DART on February 26, 2020. One author reviewed and retrieved citations from these four databases for irrelevant and duplicate studies, and two other authors independently extracted data from the studies and rated their quality.Patients with surgical treatment of bisphosphonate-related atypical femoral fracture, according to the American Society for Bone and Mineral Research definition, were included. Animal studies, case reports, studies with high-energy trauma, pathological fracture, or malignancy-related fractures were excluded.
RESULTS
In total, 316 patients (348 fractures) were included in this study. Mean age of patients was 70.47 years, and 97.5% of them were female. Duration of using bisphosphonates was 4.04 to 8.8 years, and Alendronate was the most common type. Moreover, 65.27% and 34.72% of the reported fractures were in diaphyseal and subtrochanteric, respectively. Moreover, the most common fixation type was intramedullary. Rate of complication was 17.52%, and the most frequent one was non-union, followed by implant failure. The main limitation of this research was that most of the studies did not have a high level of evidence.
CONCLUSION
An increase in the rate of atypical femoral fracture with its challenging management makes it an important issue to be noted by orthopedic surgeons. Based on the results of this study, subtrochanteric fractures might have more complications post-operatively and are suggested to be operated on by more experienced surgeons. It was also found that extra-medullary fixation increases the risk of complications. Future studies on union time, outcomes of different surgical methods, and teriparatide therapy may help shed more light on the surgical management of these fractures.

Meta-Analysis
To understand the potential and limitations of the different available surgical techniques used to treat large, long-bone diaphyseal defects by focusing on union, complication, re-intervention, and failure rates, summarizing the pros and cons of each technique. A literature search was performed on PubMed, Web of Science, and Cochrane databases up to March 16th, 2022; Inclusion criteria were clinical studies written in English, of any level of evidence, with more than five patients, describing the treatment of diaphyseal bone defects. The primary outcome was the analysis of results in terms of primary union, complication, reintervention, and failure rate of the four major groups of techniques: bone allograft and autograft, bone transport, vascularized and non-vascularized fibular graft, and endoprosthesis. The statistical analysis was carried out according to Neyeloff et al., and the Mantel-Haenszel method was used to provide pooled rates across the studies. The influence of the various techniques on union rates, complication rates, and reintervention rates was assessed by a z test on the pooled rates with their corresponding 95% CIs. Assessment of risk of bias and quality of evidence was based on Downs and Black's "Checklist for Measuring Quality" and Rob 2.0 tool. Certainty of yielded evidence was evaluated with the GRADE system. Seventy-four articles were included on 1781 patients treated for the reconstruction of diaphyseal bone defects, 1496 cases in the inferior limb, and 285 in the upper limb, with trauma being the main cause of bone defect. The meta-analysis identified different outcomes in terms of results and risks. Primary union, complications, and reinterventions were 75%, 26% and 23% for bone allografts and autografts, 91%, 62% and 19% for the bone transport group, and 78%, 38% and 23% for fibular grafts; mean time to union was between 7.8 and 8.9 months in all these groups. Results varied according to the different aetiologies, endoprosthesis was the best solution for tumour, although with a 22% failure rate, while trauma presented a more composite outcome, with fibular grafts providing a faster time to union (6.9 months), while cancellous and cortical-cancellous grafts caused less complications, reinterventions, and failures. The literature about this topic has overall limited quality. However, important conclusions can be made: Many options are available to treat critical-size defects of the diaphysis, but no one appears to be an optimal solution in terms of a safe, satisfactory, and long-lasting outcome. Regardless of the bone defect cause, bone transport techniques showed a better primary union rate, but bone allograft and autograft had fewer complication, reintervention, and failure rates than the other techniques. The specific lesion aetiology represents a critical aspect influencing potential and limitations and therefore the choice of the most suitable technique to address the challenging large diaphyseal defects.

Background Ribbing disease, or multiple diaphyseal sclerosis, is a rare benign bone dysplasia. Purpose To systematically review the literature to determine the clinical and radiological presentation of patients with Ribbing disease as well as the effects of attempted treatments. Material and Methods We considered individual patient data of patients diagnosed with Ribbing disease derived from patient reports and patient series. All stages of the review were performed by two reviewers independently. Standard descriptive statistics were used for quantitative analyses and mixed model analyses were used when appropriate Results The literature search yielded 420 unique hits of which 23 studies were included, covering a total of 40 patients of whom 29 had bilateral involvement. The mean age at diagnosis was 35 years and the mean time between diagnosis and onset of symptoms, mostly pain, was five years (range = 1-16 years). The tibial diaphysis was the most commonly involved bone in 35 of 36 patients. Non-surgical treatment consisted of non-steroidal anti-inflammatory drugs (NSAIDs), prednisone, and bisphophonates with mixed results. Surgical treatment consisted of intramedullary reaming and fenestration and was very effective to reduce pain. Conclusion The clinical presentation and imaging findings of patients with Ribbing disease are becoming more apparent. However, there is paucity of evidence on the natural disease progression and effectiveness of treatment modalities.

Review
Is Minimally Invasive Plating Osteosynthesis Better Than Conventional Open Plating for Humeral Shaft Fractures? A Systematic Review and Meta-Analysis of Comparative Studies.
INTRODUCTION
The aim of systematic review and meta-analysis was to find out whether minimally invasive plate osteosynthesis (MIPO) is better than open reduction and internal plate fixation (ORIF) in terms of functional outcome, achieving union (union time and incidence of non-union), intraoperative parameters (surgical duration, blood loss, and radiation exposure), and complications (iatrogenic radial nerve palsy and infection) for humeral shaft fractures.
MATERIALS AND METHODS
We searched online databases (Pubmed, Embase, Scopus, and The Cochrane Library) from inception till 3rd September 2020 for articles comparing MIPO with ORIF for humeral shaft fractures. The methodological quality of randomized controlled trials (RCTs) was done by Cochrane Risk of Bias assessment tool 2 (RoB2) and of non-randomized studies (case-control and cohort studies) by Methodological Index for non-randomized studies (MINORS). Meta-analysis was performed using Review Manager 5.4 software.
RESULTS
11 studies (5 RCTs and 6 non-randomized comparative studies) involving a total of 582 patients (MIPO-290, ORIF-292) meeting our inclusion criteria were included in the study. There was no statistically significant difference in pooled analysis of functional outcome scores between MIPO and ORIF. Union time was significantly lesser (mean difference = 3.12 weeks) and incidence of non-union lower (odd's ratio = 0.27) in MIPO group. Surgical duration and intraoperative blood loss were significantly lesser in MIPO group. Iatrogenic radial nerve palsy and infection were higher in ORIF group.
CONCLUSIONS
This study showed that MIPO gives similar functional outcomes as compared to ORIF but causes significantly lesser blood loss, requires lesser operative duration and has a lesser incidence of major complications.

Review
BACKGROUND
There are several studies on nonunion, but there are no systematic overviews of the current evidence of risk factors for nonunion. The aim of this study was to systematically review risk factors for nonunion following surgically managed, traumatic, diaphyseal fractures.
METHODS
Medline, Embase, Scopus, and Cochrane were searched using a search string developed with aid from a scientific librarian. The studies were screened independently by two authors using Covidence. We solely included studies with at least ten nonunions. Eligible study data were extracted, and the studies were critically appraised. We performed random-effects meta-analyses for those risk factors included in five or more studies. PROSPERO registration number: CRD42021235213.
RESULTS
Of 11,738 records screened, 30 were eligible, and these included 38,465 patients. Twenty-five studies were eligible for meta-analyses. Nonunion was associated with smoking (odds ratio (OR): 1.7, 95% CI: 1.2-2.4), open fractures (OR: 2.6, 95% CI: 1.8-3.9), diabetes (OR: 1.6, 95% CI: 1.3-2.0), infection (OR: 7.0, 95% CI: 3.2-15.0), obesity (OR: 1.5, 95% CI: 1.1-1.9), increasing Gustilo classification (OR: 2.2, 95% CI: 1.4-3.7), and AO classification (OR: 2.4, 95% CI: 1.5-3.7). The studies were generally assessed to be of poor quality, mainly because of the possible risk of bias due to confounding, unclear outcome measurements, and missing data.
CONCLUSION
Establishing compelling evidence is challenging because the current studies are observational and at risk of bias. We conclude that several risk factors are associated with nonunion following surgically managed, traumatic, diaphyseal fractures and should be included as confounders in future studies.
