Abstract
Background To determine differences in functional outcomes, return to work, and complications, in operatively vs. nonoperatively treated diaphyseal humeral shaft fractures. Methods 150 patients who presented to our center with a diaphyseal humeral shaft fracture (Orthopedic Trauma Association type 12) treated by open reduction internal fixation or closed reduction with bracing were retrospectively reviewed. Data collected included patient demographics, injury information, surgical details, and employment data. Clinical, radiographic, and patient-reported functional outcomes were recorded at routine standard-of-care follow-ups. Complications were recorded. Outcomes were analyzed using standard statistical methods and compared. Results 150 patients with a mean 24.4 months of follow-up (12 to 60 months) were included for analysis. 83 (55.3%) patients were treated with nonoperative care in a functional brace. The rest were treated surgically. The mean time to healing did not differ between the cohorts (P > .05). Patients treated operatively recovered faster with regards to functional elbow range of motion by 6 weeks (P = .039), were more likely to be back at work by 8 weeks after injury (P = .001), and demonstrated earlier mean time to return-to-daily activities (P = .005). Incidence of nonunion was higher in the nonoperative cohort (10.84% vs. 0%, P = .031). Three (4.5%) patients in the operative group developed iatrogenic, postoperative nerve palsy. Two patients in the operative group (4%) had a superficial surgical site infection. Conclusion More patients treated surgically had functional range of motion by 6 weeks. Functional gains should be weighed by the patient and surgeon against risk of surgery, nonunion, nerve injury, and infection when considering various treatment options to better accommodate patients' needs.

Abstract
INTRODUCTION Femoral shaft nonunion negatively affects patient quality of life. Although multiple risk factors have been identified for femoral shaft nonunion after intramedullary nail (IMN) fixation, there is no quantitative model for predicting nonunion. STUDY DESCRIPTION The study is a retrospective cohort study of patients with femoral shaft fractures treated at two level one trauma centers who were followed to fracture union or nonunion. Patient, injury, and surgical characteristics were analyzed to create a quantitative model for nonunion risk after intramedullary nailing. METHODS Eight hundred one patients aged 18 years and older with femoral shaft fractures treated with reamed, locked IMNs were identified. Risk factors including demographics, comorbidities, surgical variables, and injury-related characteristics were evaluated. Multivariate analysis was conducted, and several variables were included in a scoring system to predict nonunion risk. RESULTS The overall nonunion rate was 7.62% (61/801). Multivariate analysis showed significant association among pulmonary injury (odds ratio [OR] = 2.19, P = 0.022), open fracture (OR=2.36, P = 0.02), current smoking (OR=3.05, P < 0.001), postoperative infection (OR=12.1, P = 0.007), AO/OTA fracture pattern type A or B (OR=0.43, P = 0.014), and percent cortical contact obtained intraoperatively ≥25% (OR=0.41, P = 0.021) and nonunion. The scoring system created to quantitatively stratify nonunion risk showed that a score of 3 or more yielded an OR of 6.38 for nonunion (c-statistic = 0.693, P < 0.0001). CONCLUSIONS Femoral shaft nonunion risk is quantifiable based on several independent injury, patient, and surgical factors. This scoring system is an additional tool for clinical decision making when caring for patients with femoral shaft fractures treated with IMNs.

Abstract
OBJECTIVES To compare radiographic and clinical outcomes in nonoperative management of humeral shaft fractures treated initially with coaptation splinting (CS) followed by delayed functional bracing (FB) versus treatment with immediate FB. METHODS DESIGN Retrospective cohort study. SETTING Academic Level 1 Trauma Center. PATIENT SELECTION CRITERIA Patients with closed humeral shaft fractures managed nonoperatively with initial CS followed by delayed FB or with immediate FB from 2016 to 2022. Patients younger than 18 years and/or with less than 3 months of follow-up were excluded. OUTCOME MEASURES AND COMPARISONS The primary outcome was coronal and sagittal radiographic alignment assessed at the final follow-up. Secondary outcomes included rate of failure of nonoperative management (defined as surgical conversion and/or fracture nonunion), fracture union, and skin complications secondary to splint/brace wear. RESULTS Ninety-seven patients were managed nonoperatively with delayed FB (n = 58) or immediate FB (n = 39). Overall, the mean age was 49.9 years (range 18-94 years), and 64 (66%) patients were female. The immediate FB group had less smokers ( P = 0.003) and lower incidence of radial nerve palsy ( P = 0.025), with more proximal third humeral shaft fractures ( P = 0.001). There were no other significant differences in demographic or clinical characteristics ( P > 0.05). There were no significant differences in coronal ( P = 0.144) or sagittal ( P = 0.763) radiographic alignment between the groups. In total, 33 (34.0%) humeral shaft fractures failed nonoperative management, with 11 (28.2%) in the immediate FB group and 22 (37.9%) in the delayed FB group ( P = 0.322). There were no significant differences in fracture union ( P = 0.074) or skin complications ( P = 0.259) between the groups. CONCLUSIONS This study demonstrated that nonoperative treatment of humeral shaft fractures with immediate functional bracing did not result in significantly different radiographic or clinical outcomes compared to treatment with CS followed by delayed functional bracing. Future prospective studies assessing patient-reported outcomes will further guide clinical decision making. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
The tibia is the most common long bone at risk for nonunion with an annual incidence ranging from 12% to 19%. This topic continues to be an area of research as management techniques constantly evolve. A foundational knowledge of the fundamental concepts, etiology, and risk factors for nonunions is crucial for success. Treatment of tibial shaft nonunions often requires a multidisciplinary effort. This article provides guidance based on the most recent literature that can be used to aid the treating provider in the diagnosis, workup, and management of tibial shaft nonunions.

Abstract
PURPOSE To determine the feasibility and reliability of ultrasound in the assessment of humeral shaft fracture healing and estimate the accuracy of 6wk ultrasound in predicting nonunion. METHODS Twelve adults with a non-operatively managed humeral shaft fracture were prospectively recruited and underwent ultrasound scanning at 6wks and 12wks post-injury. Seven blinded observers evaluated sonographic callus appearance to determine intra- and inter-observer reliability. Nonunion prediction accuracy was estimated by comparing images for patients that united (n = 10/12) with those that developed a nonunion (n = 2/12). RESULTS The mean scan duration was 8 min (5-12) and all patients tolerated the procedure. At 6wks and 12wks, sonographic callus (SC) was present in 11 patients (10 united, one nonunion) and sonographic bridging callus (SBC) in seven (all united). Ultrasound had substantial intra- (weighted kappa: 6wk 0.75; 12wk 0.75) and inter-observer reliability (intraclass correlation coefficient: 6wk 0.60; 12wk 0.76). At 6wks, the absence of SC demonstrated sensitivity 50%, specificity 100%, positive predictive value (PPV) 100% and negative predictive value (NPV) 91% in nonunion prediction (overall accuracy 92%). The absence of SBC demonstrated sensitivity 100%, specificity 70%, PPV 40% and NPV 100% in nonunion prediction (overall accuracy 75%). Of three patients at risk of nonunion (Radiographic Union Score for HUmeral fractures < 8), one had SBC on 6wk ultrasound (that subsequently united) and the others had non-bridging/absent SC (both developed nonunion). CONCLUSIONS Ultrasound assessment of humeral shaft fracture healing was feasible, reliable and may predict nonunion. Ultrasound could be useful in defining nonunion risk among patients with reduced radiographic callus formation.

Abstract
BACKGROUND Fractures of the humerus diaphysis are common and often result from motor vehicle accidents (MVAs). Treatment methods range from nonoperative approaches to various operative techniques, including antegrade intramedullary nailing (AIMN) and dynamic compression plate (DCP) fixation. This study aimed to compare the cost effectiveness and outcomes of plating and nailing for humerus diaphyseal fractures. METHODS A retrospective cohort study involving 59 cases of humerus diaphyseal OTA/AO 12-A fractures was conducted at King Saud Medical City (KSMC), a level I trauma center located in the center region in Riyadh, Saudi Arabia. Patients treated with AIMN, anterolateral plating, or posterior plating were included. Data on demographics, clinical parameters, radiographic healing, and costs were collected and analyzed. RESULTS The average surgical duration was shorter in the AIMN group compared to the anterolateral and posterior plating groups but with no statistical significance (P > 0.05). The average length of stay (LOS) was shorter, and the change in hemoglobin levels was lower in the AIMN group when compared to other groups but without a statistically significant difference (P > 0.05). The average cost of AIMN was significantly higher than that of anterolateral and posterior plating groups (P < 0.0001). CONCLUSION While both nailing and plating procedures are options for treating OTA/AO 12-A fractures, AIMN carries a higher overall procedural cost. The practice of drain placement in our study population is likely the cause of the increased LOS in the plating groups. Relative additional analgesic requirements were associated with AIMN. Surgeons should consider meticulous hemostasis to avoid drain placement, which can decrease LOS, thus possibly decreasing unnecessary treatment costs of humerus shaft fractures.

Abstract
BACKGROUND Historically, humeral shaft fractures have been successfully treated with nonoperative management and functional bracing; however, various surgical options are also available. In the present study, we compared the outcomes of nonoperative versus operative interventions for the treatment of extra-articular humeral shaft fractures. METHODS This study was a network meta-analysis of prospective randomized controlled trials (RCTs) in which functional bracing was compared with surgical techniques (including open reduction and internal fixation [ORIF], minimally invasive plate osteosynthesis [MIPO], and intramedullary nailing in both antegrade [aIMN] and retrograde [rIMN] directions) for the treatment of humeral shaft fractures. The outcomes that were assessed included time to union and the rates of nonunion, malunion, delayed union, secondary surgical intervention, iatrogenic radial nerve palsy, and infection. Mean differences and log odds ratios (ORs) were used to analyze continuous and categorical data, respectively. RESULTS Twenty-one RCTs evaluating the outcomes for 1,203 patients who had been treated with functional bracing (n = 190), ORIF (n = 479), MIPO (n = 177), aIMN (n = 312), or rIMN (n = 45) were included. Functional bracing yielded significantly higher odds of nonunion and significantly longer time to union than ORIF, MIPO, and aIMN (p < 0.05). Comparison of surgical fixation techniques demonstrated significantly faster time to union with MIPO than with ORIF (p = 0.043). Significantly higher odds of malunion were observed with functional bracing than with ORIF (p = 0.047). Significantly higher odds of delayed union were observed with aIMN than with ORIF (p = 0.036). Significantly higher odds of secondary surgical intervention were observed with functional bracing than with ORIF (p = 0.001), MIPO (p = 0.007), and aIMN (p = 0.004). However, ORIF was associated with significantly higher odds of iatrogenic radial nerve injury and superficial infection than both functional bracing and MIPO (p < 0.05). CONCLUSIONS Compared with functional bracing, most operative interventions demonstrated lower rates of reoperation. MIPO demonstrated significantly faster time to union while limiting periosteal stripping, whereas ORIF was associated with significantly higher rates of radial nerve palsy. Nonoperative management with functional bracing demonstrated higher nonunion rates than most surgical techniques, often requiring conversion to surgical fixation.

Abstract
Current evidence suggests at least one-third of humeral shaft fractures initially managed nonoperatively will fail closed treatment, and this review highlights surgical considerations in those circumstances. Although operative indications are well-defined, certain fracture patterns and patient cohorts are at greater risk of failure. When operative intervention is necessary, internal fixation through an anterolateral approach is a safe and sensible alternative. Determining which patients will benefit most involves shared decision-making and careful patient selection. The fracture characteristics, bone quality, and adequacy of the reduction need to be carefully evaluated for the specific operative risks for individuals with certain comorbid conditions, inevitably balancing the patient's expectations and demands against the probability of infection, nerve injury, or nonunion. As our understanding of the etiology and risk of nonunion and symptomatic malunion of the humeral diaphysis matures, adhering to the principles of diagnosis and treatment becomes increasingly important. In the event of nonunion, respect for the various contributing biological and mechanical factors enhances the likelihood that all aspects will be addressed successfully through a comprehensive solution. This review further explores specific strategies to definitively restore function of the upper extremity with the ultimate objective of an uninfected, stable union.

Abstract
Introduction Humerus shaft nonunions are very disabling and challenging to treat. The current study aims to analyse the rate of union and the incidence of complications following a consistent protocol in treating humerus shaft nonunion. Methodology We did a retrospective analysis of 100 patients with humerus shaft nonunion treated over an eight-year period from 2014 to 2021. The mean age was 42 years (range 18-75 years). There were 53 male and 47 female patients. The average time interval from injury to nonunion surgery was 23 months (range 3 months to 23 years). The series included 12 recalcitrant nonunions and 12 patients with septic nonunion. All patients underwent freshening of fracture edges to increase the contact surface area, stable fixation with a locking plate and intramedullary iliac crest bone grafting. Infective nonunions were treated in a staged manner, following a similar treatment protocol after the elimination of infection in the first stage. Results Complete union was achieved in 97% of the patients with a single procedure. One patient achieved union after an additional procedure, while two patients were lost to further follow-up. The mean time to union was 5.7 months (range 3-10 months). Three patients (3%) had postoperative radial nerve palsy, which recovered completely within 6 months. Three patients (3%) had a superficial surgical site infection, while one patient (1%) developed a deep infection. Conclusion Intramedullary cancellous autologous grafts combined with stable fixation by compression plating achieve a high union rate with minimal complications. Level of Evidence III.

[PMID: 37035617 PMCID: PMC10078821 DOI: 10.1177/17585732211050224] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2021] [Revised: 09/12/2021] [Accepted: 09/13/2021] [Indexed: 11/15/2022]
Abstract
Background The aim of this study was to evaluate the use of patient reported experience measures (PREMs) in humeral shaft fractures managed with or without surgery against patient reported outcome measures (PROMs). Methods Adult patients treated for a humeral shaft fracture between June 2015 and August 2017 were included in non-surgery and surgery (early and late surgery) groups. The PREM questionnaire was based on patient and clinician feedback obtained during focus groups and was posted to patients. PROMs included the short form-12 (SF-12) and visual analogue scale (VAS) for pain, stiffness, function and satisfaction. Results Eighty-one patients responded, 54 patients were treated in a brace and 27 with surgery (13 early, 14 late). There was moderate positive correlation between PREM and VAS satisfaction and function and moderate negative correlation with VAS pain and stiffness. There was also moderate positive correlation between PREM and SF-12 mental and weak positive correlation with SF-12 physical. The late surgery group had poorer PREMs (expectations, p = 0.002 and friends & family test, p = 0.0001) and PROMs (VAS satisfaction, p = 0.005) compared to the early surgery group. Conclusions PREMs can be used in conjunction with PROMs to improve the patient's quality of care and as a means of identifying, at an early stage, those patients not doing well and to offer surgery.

Abstract
Aseptic humeral shaft nonunions are rare lesions, with less than 700 cases per year in France. This low frequency explains why they are difficult to manage. They can be hypertrophic or atrophic, with or without a defect. The diagnosis is made based on radiographs and/or CT scan images. Nonunion is suspected early on when a patient presents with abnormal motion at the fracture site 6 weeks after the initial injury event in the context of conservative treatment or has large residual displacement after initial treatment or an open fracture. The treatment for hypertrophic nonunion consists in applying stable, rigid fixation, most often using a large-fragment plate with 4.5 mm screws, combined with cancellous autograft. When combined with the osteoperiosteal decortication first described by Judet, it produces union in 98% of cases. Intramedullary (IM) nail fixation with an autograft is another possibility. In atrophic nonunions, resecting the ends and ensuring the soft tissues have good vitality will generally lead to fracture union. Nonunions with critical size defects (larger than 5 cm), which have a high risk of infection, are a treatment challenge that requires stable fixation and recourse to more complex treatments like the two-step induced membrane technique or vascularized fibular graft. In all cases, to avoid complex repeat revision, internal fixation with plate or IM nail must be combined with a bone graft in situ to maximize the chances of union.

Abstract
INTRODUCTION The aim was to compare surgical and nonsurgical management for adults with humeral shaft fractures in terms of patient-reported upper limb function, health-related quality of life, radiographic outcomes, and complications. METHODS MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, PubMed, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, International Clinical Trials Registry, and OpenGrey (Repository for Grey Literature in Europe) were searched in September 2021. All published prospective randomized trials comparing surgical and nonsurgical management of humeral shaft fractures in adults were included. Of 715 studies identified, five were included in the systematic review and four in the meta-analysis. Data were extracted by two independent reviewers according to the Preferred Reporting Items for Systematic Review and Meta-Analysis statement. Methodological quality was assessed using the revised Cochrane risk-of-bias tool for randomized trials. Pooled data were analyzed using a random-effects model. RESULTS The meta-analysis comprised 292 patients (mean age 41 [18 to 83] years, 67% male). Surgery was associated with superior Disabilities of the Arm, Shoulder and Hand (DASH) and Constant-Murley scores at 6 months (mean DASH difference 7.6, P = 0.01; mean Constant-Murley difference 8.0, P = 0.003), but there was no difference at 1 year (DASH, P = 0.30; Constant-Murley, P = 0.33). No differences in health-related quality of life or pain scores were found. Surgery was associated with a lower risk of nonunion (0.7% versus 15.7%; odds ratio [OR] 0.13, P = 0.004). The number needed to treat with surgery to avoid one nonunion was 7. Surgery was associated with a higher risk of transient radial nerve palsy (17.4% versus 0.7%; OR 8.23, P = 0.01) but not infection (OR 3.57, P = 0.13). Surgery was also associated with a lower risk of reintervention (1.4% versus 19.3%; OR 0.14, P = 0.04). CONCLUSIONS Surgery may confer an early functional advantage to adults with humeral shaft fractures, but this is not sustained beyond 6 months. The lower risk of nonunion should be balanced against the higher risk of transient radial nerve palsy. LEVEL OF EVIDENCE Level I.

Abstract
Background Humeral shaft fractures occur frequently in older patients. The more proximal end of the shaft is prone to non-union when compared with more distal fractures. We provide an overview of several key features of this significant patient group. Method Our institutional fracture database was searched for all cases of proximal third humeral shaft fractures in patients over 60 years of age. Retrospective evaluation of patient demographics, management, length of stay and incidence of non-union was performed. Results 75 patients (61 female) were analysed. 33 patients were 'frail' (Clinical Frailty Scores of >4). Non-union occurred in 19 of 45 non-surgically treated fractures and in 1 of 37 cases treated surgically. Mean length of stay was 5.9 days (non-operative) and 6.6 days (operative). Proximal extension into the humeral head is common. Conclusion Non-surgical management of proximal third humeral shaft fractures is associated with an increased risk of non-union. We detail an operative technique and case example supporting early fixation of displaced proximal third humeral shaft fractures in older patients that can be utilized for both primary and delayed fixation. In view of the significant association of non-union a well-constructed prospective cohort study with outcome assessment would be of value to further characterize this emerging injury population.Level of Evidence: Level IV, retrospective case series.

Abstract
PURPOSE OF REVIEW The purpose of this review is to summarize the clinical and basic science methods used to assess fracture healing and propose a framework to improve the translational possibilities. RECENT FINDINGS Mainstays of fracture healing assessment include clinical examination, various imaging modalities, and assessment of function. Pre-clinical studies have yielded insight into biomechanical progression as well as the genetic, molecular, and cellular processes of fracture healing. Efforts are emerging to identify early markers to predict impaired healing and possibly early intervention to alter these processes. Despite of the differences in clinical and preclinical research, opportunities exist to unify and improve the translational efforts between these arenas to develop and optimize our ability to assess and predict fracture healing, thereby improving the clinical care of these patients.

Abstract
BACKGROUND Humeral shaft fractures can be managed operatively or nonoperatively with functional bracing in the absence of neurovascular injury, open fracture, or polytrauma. A consensus on optimal management has not been reached, nor has the cost-effectiveness perspective been investigated. METHODS A decision tree was constructed describing the management of humeral shaft fractures with open reduction-internal fixation (ORIF), intramedullary nailing (IMN), and functional bracing in a non-elderly population. Probabilities were defined using weighted averages determined from systematic review of the literature. Cost-effectiveness was evaluated with incremental cost-effectiveness ratios, measured in cost per quality-adjusted life-year (QALY). Willingness-to-pay thresholds of $50,000/QALY and $100,000/QALY were evaluated. RESULTS Eighty-six studies were included. Using bracing as the referent in the health care model, we observed that bracing was the preferred strategy at both incremental cost-effectiveness ratio thresholds. ORIF and IMN had higher overall effectiveness (0.917 QALYs and 0.913 QALYs, respectively) compared with bracing (0.877 QALYs). The cost-effectiveness of bracing was driven by a substantially lower overall cost. In the societal model-accounting for both health care and societal costs-the cost difference narrowed between bracing, ORIF, and IMN. Bracing remained the preferred strategy at the $50,000/QALY threshold; ORIF was preferred at the $100,000/QALY threshold. ORIF and IMN were comparable strategies across a range of probability values in sensitivity analyses. CONCLUSIONS Functional bracing, with its low cost and satisfactory clinical outcomes, is often the most cost-effective strategy for humeral shaft fracture management. ORIF becomes preferable at the higher willingness-to-pay threshold when societal burden is considered. QALY values for ORIF and IMN were comparable.

Abstract
Aims The primary aim was to estimate the cost-effectiveness of routine operative fixation for all patients with humeral shaft fractures. The secondary aim was to estimate the health economic implications of using a Radiographic Union Score for HUmeral fractures (RUSHU) of < 8 to facilitate selective fixation for patients at risk of nonunion. Methods From 2008 to 2017, 215 patients (mean age 57 yrs (17 to 18), 61% female (n = 130/215)) with a nonoperatively managed humeral diaphyseal fracture were retrospectively identified. Union was achieved in 77% (n = 165/215) after initial nonoperative management, with 23% (n = 50/215) uniting after surgery for nonunion. The EuroQol five-dimension three-level health index (EQ-5D-3L) was obtained via postal survey. Multiple regression was used to determine the independent influence of patient, injury, and management factors upon the EQ-5D-3L. An incremental cost-effectiveness ratio (ICER) of < £20,000 per quality-adjusted life-year (QALY) gained was considered cost-effective. Results At a mean of 5.4 yrs (1.2 to 11.0), the mean EQ-5D-3L was 0.736 (95% confidence interval (CI) 0.697 to 0.775). Adjusted analysis demonstrated the EQ-5D-3L was inferior among patients who united after nonunion surgery (β = 0.103; p = 0.032). Offering routine fixation to all patients to reduce the rate of nonunion would be associated with increased treatment costs of £1,542/patient, but would confer a potential EQ-5D-3L benefit of 0.120/patient over the study period. The ICER of routine fixation was £12,850/QALY gained. Selective fixation based on a RUSHU < 8 at six weeks post-injury would be associated with reduced treatment costs (£415/patient), and would confer a potential EQ-5D-3L benefit of 0.335 per ‘at-risk patient’. Conclusion Routine fixation for patients with humeral shaft fractures to reduce the rate of nonunion observed after nonoperative management appears to be a cost-effective intervention at five years post-injury. Selective fixation for patients at risk of nonunion based on their RUSHU may confer even greater cost-effectiveness, given the potential savings and improvement in health-related quality of life.

Abstract
BACKGROUND The outcome of non-surgical treatment is generally good, but the treatment course can be long and painful with approximately a quarter of the patients acquiring a nonunion. Both surgical and non-surgical treatment can have disabling consequences such as nerve injury, infection, and nonunion. The purpose of the study is to compare patient-reported outcomes after surgical and non-surgical treatment for humeral shaft fractures. METHODS A pragmatic randomized controlled trial (RCT) is planned with two study groups (SHAFT-Young and SHAFT-Elderly). A total of 287 eligible acute humeral shaft fractures are scheduled to be recruited and randomly allocated to surgical or non-surgical treatment with the option of early crossover due to delayed union. The surgical method within the allocation is decided by the surgeon. The primary outcome is the Disability of Arm, Shoulder, and Hand (DASH) score at 52 weeks, and is assessor blinded. The secondary outcomes are DASH score, EQ-5D-5L, pain assessed by visual analog score, Constant-Murley score including elbow range of motion, and anchor questions collected at all timepoints throughout the trial. All complications will be reported including; infection, nerve or vascular injury, surgical revisions (implant malpositioning, hardware failure, aseptic loosening, and peri-implant fracture), major adverse cardiovascular events, and mortality. DISCUSSION The SHAFT trial is a pragmatic multicenter RCT, that will compare the effectiveness of the main strategies in humeral shaft fracture treatment. This will include a variety of fracture morphologies, while taking the dilemmas within the population into account by splitting the population by age and providing the orthopedic society with an interval for early crossover surgery.

Abstract
BACKGROUND Non-union in non-operatively managed humeral shaft fractures are associated with significant morbidity. Hence, developing a robust system that could help with early diagnosis is important. We aimed to evaluate the validity of the Radiographic Union Score for HUmeral fractures (RUSHU) at 6 weeks (RUSHU-6) and test whether a RUSHU at 12 weeks (RUSHU-12) would be a better predictor of non-union. METHODS We retrospectively reviewed all non-operatively managed humeral diaphyseal fractures from 2012 to 2018. Statistical analysis was used to determine the cut-off RUSHU-12 and evaluate the effect of RUSHU-6 and RUSHU-12 on non-union prediction. RESULTS In sum, 32 patients had radiographs at 6 weeks post-injury, 27 of which also had radiographs at 12 weeks. A RUSHU cut-off of 9 was the best predictor of non-union at 12 weeks. Only RUSHU-12 had a statistically significant influence predicting non-union (P = 0.011) and there was a significant correlation (P = 0.003) between score progression from RUSHU-6 to RUSHU-12 and the development of non-union. DISCUSSION A RUSHU-12 of <9 and a low score progression between 6 and 12 weeks suggest superior predictive value in determining the likelihood of non-union. Further validation in the form of a large multicentred study is however required.

Abstract
OBJECTIVES The primary aim was to assess patient-reported outcomes ≥1 year following a humeral diaphyseal fracture. The secondary aim was to compare outcomes of patients who united after initial management (operative/nonoperative) with those who united after nonunion fixation (NU-ORIF). DESIGN Retrospective. SETTING University teaching hospital. PATIENTS AND INTERVENTION From 2008 to 2017, 291 patients [mean age, 55 years (17-86 years), 58% (n = 168/291) female] were available to complete an outcomes survey. Sixty-four (22%) were initially managed operatively and 227 (78%) nonoperatively. After initial management, 227 (78%) united (n = 62 operative, n = 165 nonoperative), 2 had a delayed union (both nonoperative), and 62 (21%) had a nonunion (n = 2 operative, n = 60 nonoperative). Fifty-two patients (93%, n = 52/56) united after NU-ORIF. MAIN OUTCOME MEASURES QuickDASH, EuroQol-5 Dimension (EQ-5D)/EuroQol-Visual Analogue Scale (EQ-VAS), 12-item Short Form Physical (PCS) and Mental Component Summary (MCS). RESULTS At a mean of 5.5 years (range, 1.2-11.0 years) postinjury, the mean QuickDASH was 20.8, EQ-5D was 0.730, EQ-VAS was 74, PCS was 44.8 and MCS was 50.2. Patients who united after NU-ORIF reported worse function (QuickDASH, 27.9 vs. 17.6; P = 0.003) and health-related quality of life (HRQoL; EQ-5D, 0.639 vs. 0.766; P = 0.008; EQ-VAS, 66 vs. 76; P = 0.036; PCS, 41.8 vs. 46.1; P = 0.036) than those who united primarily. Adjusting for confounders, union after NU-ORIF was independently associated with a poorer QuickDASH (difference, 8.1; P = 0.019) and EQ-5D (difference, -0.102; P = 0.028). CONCLUSIONS Humeral diaphyseal union after NU-ORIF resulted in poorer patient-reported outcomes compared with union after initial management. Targeting early operative intervention to at-risk patients may mitigate the potential impact of nonunion on longer-term outcome. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
INTRODUCTION Fracture treatment has been documented since the times of ancient Egyptian and Greek civilization, with fracture reduction techniques and the apparatus for immobilization developed over three millennia. Over the last 150 years, aseptic technique, anesthesia, antibiotics, and internal implants have changed how orthopedic specialists approach fracture care. More recently, there has been an increased promotion in the medical literature to evaluate the clinical outcomes of nonsurgical treatment of common upper and lower extremity closed fractures. METHODS In this paper, the authors review the history of closed extremity fracture treatments, outline contemporary studies regarding treatments of non-displaced fractures, and discuss the recent literature that has informed orthopedic surgeon-patient decision-making discussions regarding closed fracture management. CONCLUSIONS Based on the results of this literature review, orthopedic providers should consider the preferable outcomes associated with nonoperative fracture management such as lower infection rates, the possibility of rapid functional improvements and lower healthcare costs. Nonoperative methods for closed fractures can sometimes be more safely delivered even with more difficult fractures. This may be of particular benefit to patients with higher surgical risks, minimizing exposure to treatments that are not only more invasive and expensive, but that can impose greater postoperative risks.

Approach to Humeral Shaft Nonunion: Evaluation and Surgical Techniques. J Am Acad Orthop Surg 2022; 30:50-59.

Abstract
Humeral shaft fractures account for 1% to 3% of all fractures. Traditional nonsurgical treatment with a functional brace is still the standard treatment of these fractures; however, modern studies have reported that nonunion rates may be as high as 33%. Recent information suggests that the development of nonunion after nonsurgical treatment may be identified as early as 6 to 8 weeks postinjury. Even with surgical treatment, nonunion rates as high as 10% have been reported. Regardless of the original treatment method, nonunion results in poor quality of life for the patient and therefore should be addressed. A thorough preoperative evaluation is important to identify any metabolic or infectious factors that may contribute to the nonunion. In most cases, surgical intervention should consist of compression plating with or without bone graft. Although most patients will achieve union with standard surgical intervention, some patients may require specialized techniques such as cortical struts or vascularized fibular grafts. Successful treatment of humeral shaft nonunion improves function, reduces disability, and improves the quality of life for patients. In this article, we outline our approach to the treatment of humeral shaft nonunion in a variety of clinical settings.

Abstract
Background Expandable magnetic rods and intramedullary nails are being used in a number of innovative ways, including limb length discrepancy and scoliosis correction. However, recently, the full complement of these devices has been further explored, with the utilization of their compressive capacity to improve fracture healing. The purpose of the present study was to report on early results of compressive magnetic intramedullary nailing for humeral shaft delayed unions and nonunions. Methods This retrospective case series was completed at a level 1 trauma center, with adult patients who underwent compressive intramedullary nailing from 2017 to 2021 for humeral shaft nonunion or delayed union. The primary indication for this procedure was nonunion in the setting of previous conventional fixation, but a subset of patients with atrophic nonunions and risk factors for recalcitrant nonunion were also included. Results Fourteen patients, with a mean age of 51 ± 17 years, underwent compressive magnetic intramedullary nailing. Nine patients had previously underwent surgery, 6 of which had undergone multiple prior procedures. Five others were initially treated nonoperatively and underwent surgery 4.1 ± 2.9 months out from injury. Ten patients went on to union at a mean of 2.9 ± 2.4 months. One patient experienced hardware failure with nail cut-out at 2 weeks, and one required revision surgery for a wound infection. Three other patients were lost to follow-up, one of which was deceased for reasons unrelated to surgery. Conclusion Compressive magnetic intramedullary nails are a viable solution for complex humeral shaft nonunions, particularly in the setting of previously well-fixed fractures and those at risk of recalcitrant nonunion. However, comparative and prospective studies looking at union rates and secondary procedures are needed to more clearly define their role in treatment and assure their safety, given recent concerns regarding osteolysis at the nail modular junction.

Risk Factors for Development of a Recalcitrant Femoral Nonunion: A Single Surgeon Experience in 122 Patients. J Orthop Trauma 2021; 35:619-625. [PMID: 34596060 DOI: 10.1097/bot.0000000000002276] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 09/15/2021] [Indexed: 02/02/2023]
Abstract
OBJECTIVES The goals of the study were (1) to document the healing rates of femoral nonunions stratified by those that healed as intended, healed after a subsequent intervention, and those that did not heal; (2) to report the prevalence of recalcitrant femoral nonunions and (3) to identify specific demographic, injury, and treatment-related risk factors for the development of a recalcitrant nonunion. DESIGN Longitudinal observational cohort study. SETTING Academic Level 1 trauma center. PATIENTS/PARTICIPANTS One hundred twenty-two femoral nonunions treated with either a plate or intramedullary nail by a single surgeon between 1991 and 2018. INTERVENTION Bivariate and multivariate regression analysis were performed to identify specific demographic, injury, and treatment factors in patients who developed a recalcitrant nonunion. RESULTS Although 83.6% of the femoral nonunions eventually healed, only 66% "healed as intended" with 17.2% requiring 1 or more additional procedures to consolidate and 16.4% of nonunions failing to unite. There were no statistically significant differences in the recalcitrance rate when we compared treatment with conventional versus locked plates or primary versus exchange nailing. Risk factors for developing a recalcitrant nonunion were deep infection, current smokers, metabolic bone disease, and patients who had undergone 3 or more prior surgical procedures. CONCLUSIONS The use of both intramedullary nails and modern plates were associated with a high rate of recalcitrance. Infection, current smokers, metabolic bone disease, and 3 or more prior surgical procedures were predictors for the development of a recalcitrant nonunion. LEVEL OF EVIDENCE Therapeutic Leve IV.

Predicting the Behavior of Humeral Shaft Fractures: An Independent Validation Study of the Radiographic Union Score for HUmeral Fractures and Value of Assessing Fracture Mobility. J Orthop Trauma 2021; 35:555-559.

Abstract
OBJECTIVES To externally validate the Radiographic Union Score for HUmeral fractures (RUSHU) and to quantify the predictive relationship of fracture motion on physical examination to nonunion. DESIGN Retrospective cohort study. SETTING Single institutional center (University teaching hospital). PATIENTS Ninety-two consecutive patients undergoing nonoperative treatment of a diaphyseal humeral shaft fracture were identified over a 4-year period. The average age of the population was 62 years and 42% of the cohort was men. INTERVENTION Clinical examination for fracture stability was routinely performed on patients by the treating physicians. Radiographic assessment of fracture callus (RUSHU score) at 6 weeks was retrospectively determined. Patients were followed up until union. MAIN OUTCOME MEASUREMENTS Stability was graded as motion at the fracture site or the humerus moving as a single functional unit. RESULTS Fractures with a RUSHU score ≤7 were 14 times more likely to proceed to nonunion at 6 months (78% sensitivity, 80% specificity). The time to union was 49 weeks for a RUSHU score of ≤7 versus 16 weeks for a RUSHU score of ≥8. The number of operations needed to avoid one nonunion was 1.7. Fractures mobile at 6 weeks were 6.5 times more likely to proceed to nonunion at 6 months (77% specificity, 67% sensitivity). Mobile fractures had a longer time to union (41 weeks) than nonmobile fractures (17 weeks). CONCLUSION The RUSHU score and clinical assessment of fracture mobility are effective and valid tools in identifying patients at risk of developing nonunion of humeral shaft fractures and can enhance early decision making in fracture management.

Abstract
BACKGROUND The primary aim was to identify patient and injury factors independently associated with humeral diaphyseal fracture nonunion after nonoperative management. The secondary aim was to determine the effect of management (operative/nonoperative) on nonunion. METHODS From 2008-2017, a total of 734 humeral shaft fractures (732 consecutive skeletally mature patients) were retrospectively identified from a trauma database. Follow-up was available for 663 fractures (662 patients, 90%) that formed the study cohort. Patient and injury characteristics were recorded. There were 523 patients (79%) managed nonoperatively and 139 (21%) managed operatively. Outcome (union/nonunion) was determined from medical records and radiographs. RESULTS The median age at injury was 57 (range 16-96) years and 54% (n = 359/662) were female. Median follow-up was 5 (1.2-74) months. Nonunion occurred in 22.7% (n = 119/524) of nonoperatively managed injuries. Multivariate analysis demonstrated preinjury nonsteroidal anti-inflammatory drugs (NSAIDs; odds ratio [OR] 20.58, 95% confidence interval [CI] 2.12-199.48; P = .009) and glenohumeral arthritis (OR 2.44, 95% CI 1.03-5.77; P = .043) were independently associated with an increased risk of nonunion. Operative fixation was independently associated with a lower risk of nonunion (2.9%, n = 4/139) compared with nonoperative management (OR for nonoperative/operative management 9.91, 95% CI 3.25-30.23; P < .001). Based on these findings, 5 patients would need to undergo primary operative fixation in order to avoid 1 nonunion. CONCLUSIONS Preinjury NSAIDs and glenohumeral arthritis were independently associated with nonunion following nonoperative management of a humeral diaphyseal fracture. Operative fixation was the independent factor most strongly associated with a lower risk of nonunion. Targeting early operative fixation to at-risk patients may reduce the rate of nonunion and the morbidity associated with delayed definitive management.

Abstract
Fracture non-union is a significant orthopaedic problem affecting a substantial number of patients yearly. Treatment of nonunions is devastating to patients and costly to the healthcare system. Unfortunately, the diagnosis of non-union is typically made in a reactionary fashion by an orthopaedic surgeon based on clinical assessment and radiographic features several months into treatment. For this reason, investigators have been trying to develop prediction algorithms; however, these have relied on population-based approaches and lack the predictive capability necessary to make individual treatment decisions. There is also a growing body of literature focussed on identifying blood biomarkers that are associated with non-union. This review describes the research that has been done in this area. Further studies of patient-centered, precision medicine approaches will likely improve fracture non-union diagnostic/prognostic capabilities.

Abstract
The human skeleton has remarkable regenerative properties, being one of the few structures in the body that can heal by recreating its normal cellular composition, orientation and mechanical strength. When the healing process of a fractured bone fails owing to inadequate immobilization, failed surgical intervention, insufficient biological response or infection, the outcome after a prolonged period of no healing is defined as non-union. Non-union represents a chronic medical condition not only affecting function but also potentially impacting the individual's psychosocial and economic well-being. This Primer provides the reader with an in-depth understanding of our contemporary knowledge regarding the important features to be considered when faced with non-union. The normal mechanisms involved in bone healing and the factors that disrupt the normal signalling mechanisms are addressed. Epidemiological considerations and advances in the diagnosis and surgical therapy of non-union are highlighted and the need for greater efforts in basic, translational and clinical research are identified.

Abstract
Nonunion following a long bone fracture causes considerable morbidity when it occurs. Risk factors depend on specific fractures but there is a complex interplay of injury severity, comorbidities, patient medication and infection. The majority of nonunions occur after long bone fractures with the tibia, femur, forearm, humerus and clavicle predominating. Despite interest in the biological augmentation of fracture healing, the majority of nonunions can be effectively managed with conventional surgical techniques. In this review we present a review of risk factors for nonunion and the outcome following surgical management.

Abstract
Fracture nonunion causes considerable patient morbidity and an associated burden to society. Traditional reliance on radiographs to monitor union has limitations as bridging callus of long bone fractures can take three or more months to occur. Computed Tomographic (CT) scanning is becoming increasingly popular and can evaluate bridging callus in the late stages of healing to confirm union. The use of dynamic contrast enhanced Magnetic Resonance Imaging (MRI) and advances in nuclear imaging may yield benefits in the assessment of the infected nonunion. Emerging evidence supports the use of ultrasound to detect bridging callus prior to radiographic confirmation and it may be of use to predict patients at high risk of nonunion. This paper is part of a Supplement supported by The Osteosynthesis and Trauma Care Foundation (OTCF).

Abstract
BACKGROUND Clavicle nonunions often result after nonoperative treatment for the acute fracture. Those that require >1 surgical procedure in order for a nonunion to heal are termed recalcitrant. The aims of the present study were to (1) determine healing rates of clavicle nonunions after plate osteosynthesis using either a conventional or locked plate, (2) compare iliac crest bone graft vs. bone morphogenetic protein on nonunion healing, and (3) identify risk factors for the development of a recalcitrant nonunion. METHODS We performed a retrospective analysis of a prospectively collected database of 78 clavicle nonunions treated with open reduction and plate fixation with or without graft augmentation by a single surgeon over 25 years. Seventy-one patients over the age of 18 with at least 12 months of follow-up comprised the study group. We analyzed healing rates after the index clavicle nonunion surgery comparing plate type and graft technique as well as identifying risk factors for developing a recalcitrant nonunion. RESULTS A total of 62 patients (87.3%) healed after their index nonunion surgery at our institution. Three patients (4.2%) required additional surgery but healed, and 6 patients (8.5%) remain un-united; these 9 patients (12.7%) were defined as recalcitrant. There was no statistically significant difference in healing rates between plate type (P = .633) or type of bone graft (P = .157). There were no identifiable risk factors for the development of a recalcitrant nonunion. CONCLUSIONS Plate fixation of clavicle nonunions remains a successful method of treatment. The type of plate or the method of bone graft did not produce different results. There were no demographic, patient, or injury characteristics associated with the development of a recalcitrant nonunion.

Abstract
OBJECTIVES To establish the reliability of 2 radiographic union scoring systems for nonoperative humeral shaft fractures. DESIGN Retrospective medical record review. Patients identified had humeral shaft fractures and radiographs at various follow-up time points, which were graded according to the both the standard (RUST) and modified radiographic union scoring systems (mRUST). SETTING A single North American Level-1 Trauma center in Connecticut, including emergency department and clinic follow-up visits. PATIENTS/PARTICIPANTS Forty-five adult patients (162 image sets) met the following inclusion criteria: diaphyseal humerus fracture, initial nonoperative management, and greater than 2 weeks of follow-up with imaging. INTERVENTION All 162 image sets of anterior-posterior and lateral radiographs were scored and divided into 4 tiers based on increasing score. Anterior-posterior and lateral image sets were randomly selected from each tier for a total of 50 that were then scored by 7 different reviewers using both the RUST and mRUST systems. MAIN OUTCOME MEASURES The intraclass correlation coefficients for the cortical and system scores for the RUST and mRUST systems. RESULTS Interobserver reliability was 0.795 for the RUST system and 0.801 for mRUST. Intraobserver reliability was 0.909 for RUST and 0.949 for mRUST. For mRUST, 92% of values were within ± 1 point from each other. CONCLUSIONS The RUST and mRUST systems can be applied to humeral shaft fractures with excellent reliability. They have the potential to assist in the diagnosis of humeral shaft union by providing an objective and standardized method to assess healing of bone over time.

J Shoulder Elbow Surg 2020; 29:2495-2504.

Abstract
BACKGROUND The humeral shaft fracture accounts for 1%-3% of all fractures and occurs in both the young and old population. However, the optimal treatment is still a matter of debate. Even though nonoperative treatment is commonly considered the gold standard, advantages have been described using operative stabilization. This systematic review aims to compare operative and nonoperative treatment in adult patients with humeral shaft fractures. METHOD We used the following databases: PubMed, Embase, Cochrane, and CINAHL on October 1, 2018, searching for randomized controlled trials (RCTs) and cohort studies. Two reviewers screened the studies using Covidence, followed by systematic data extraction. The primary outcome was defined as posttreatment complications such as nonunion, radial nerve palsy, malunion, and infections. The secondary outcomes were functional scores and patient-reported outcome measures (PROMs). To assess study quality, the risk of bias in nonrandomized studies of interventions and the Cochrane risk of bias tool were used. RESULTS Twelve studies were included: 1 RCT, 1 prospective cohort, and 10 retrospective cohorts with a total of 1406 patients, of whom 835 were treated operatively and 571 nonoperatively. Mean age ranged from 35 to 64, and 54% of the patients were male. The cohort studies had, in general, moderate bias, whereas the RCT had a low bias. There were statistically significant fewer nonunions in the operative treated group with a risk ratio of 0.49 (0.35-0.67), yielding a number needed to treat = 12. There were more deep infections in the operative group with a risk ratio of 2.76 (1.01-7.53) but otherwise no statistical differences concerning malunion or nerve damage. Only 1 study included PROM data. CONCLUSION There were fewer nonunions in the operative group but more deep infections. Because of the lack of studies reporting PROMs, the potential positive effect of operative therapy in early aftercare could not be evaluated. Therefore, PROMs should be mandatory in future comparative studies.

Abstract
CASE Two patients who developed radial nerve palsy at least 6 weeks after injury during nonoperative treatment of humeral shaft fractures. This complication was associated with external bracing, progressive varus angulation during treatment, and excess callus formation. CONCLUSION Delayed radial nerve palsy may develop during nonoperative treatment of humeral shaft fractures when functional bracing fails to maintain alignment and stability at the fracture site.

Abstract
BACKGROUND Humeral shaft fractures are common but debate still occurs as to whether these are best managed operatively or non-operatively. We sought to undertake a systematic review and meta-analysis of randomised and non-randomised studies to clarify the optimal treatment. METHODS We performed a search for all randomised and non-randomised comparative studies on humeral shaft fracture. We included only those with an operative and non-operative cohort in adult patients. We undertook a meta-analysis of the following outcome measures: nonunion, malunion, delayed union, iatrogenic nerve injury and infection. Non-operative management was with a functional brace. RESULTS Non-operative management resulted in a significantly higher nonunion rate of 17.6% compared to 6.3% with fixation. Operative management had a significantly higher iatrogenic nerve injury rate of 3.4% and infection rate of 3.7%. All nonunions within the included studies went on to union after plate fixation. There was no significant difference in delayed union or patient reported outcome measures. There was a significantly increased risk of malunion with non-operative treatment however this did not correlate with the outcome. DISCUSSION Our findings suggest that in the majority of cases, humeral shaft fractures can be managed with non-operative treatment, and any subsequent nonunion should be treated with plate fixation.

Abstract
PURPOSE The optimal treatment protocol for humeral shaft fractures at risk for nonunions is controversial. Here, we aim to describe magnetic intramedullary compression nailing as an option for these challenging scenarios and to evaluate its clinical and radiographic outcomes. METHODS This retrospective case series was performed at an urban university-based level-1 trauma center. Patients aged 18-65 who underwent fixation of their at-risk humerus shaft fracture using the PRECICE nail were included in this investigation. These fractures are characterized by a persistent distraction gap, minimal callous formation, or malalignment greater than 20 degrees. The study data were collected through a retrospective chart review and review of the radiographic studies. Primary outcome measure was radiographic union. Secondary outcome measures included mechanical failure, nonunion, malunion, medical, and surgical complications. Functional outcome was determined by range of motion and restoration of rotator cuff strength. RESULTS A total of six patients were included who underwent treatment of their humeral shaft fracture with a NuVasive PRECICE nail after failure of conservative management. After nail placement along with our compression protocol, all patients achieved bony union and experienced favorable outcomes with return to their previous working status. Two complications included a superficial incisional infection treated with antibiotics and a backing out of proximal screw which did not cause discomfort. No other mechanical failures, surgical complications, or medical complications occurred. CONCLUSIONS Early results of controlled compression nailing for humeral shaft fracture demonstrated favorable clinical outcomes. This technique may be utilized for these challenging situations.

Abstract
Nonoperative treatment has become the standard of care for the majority of humeral shaft fractures. Published studies have mainly come from trauma centers with a young cohort of patients. The purpose of this study was to determine the nonunion rate of humeral shaft fractures in patients older than 55 years. A retrospective study was performed on a group of orthopedic trauma group treated at a level I trauma center during a 10-year period (2007-2017). Patients 55 years or older and treated for a humeral shaft fracture nonoperatively, with or without manipulation, were identified. Nonunion was defined by no bridging callus radiographically or by gross motion at the fracture at least 12 weeks from injury. There were 31 patients identified with humeral shaft fractures who met the inclusion criteria. The cohort included 21 (67.7%) females and 10 (32.3%) males with a mean age of 72.5 years (range, 55-92 years). Twenty-one fractures went on to union, and there were 10 nonunions, with no significant differences in the demographics or comorbidities. There was no correlation between AO/OTA fracture classification or fracture location and union status. There was a tendency toward higher risk of nonunion in proximal third humeral shaft fractures (45%) compared with middle (26%) and distal third (20%) humeral shaft fractures, although this was not statistically significant. The overall nonunion rate for humeral shaft fractures was 32% for patients older than 55 years. The authors found a significant correlation between age and union rate: as age increased, union rate decreased (R=-0.9, P=.045). The incidence of humeral shaft nonunion in patients older than 55 years was significantly higher than that of younger adults. To the authors' knowledge, this study is the first to report a significant correlation between nonunion and increased age. [Orthopedics. 2020;43(3);168-172.].

Abstract
OBJECTIVES To evaluate the rate of, and reasons for, conversion of closed treatment of humeral shaft fractures using a fracture brace, to surgical intervention. DESIGN Multicenter, retrospective analysis. SETTING Nine Level 1 trauma centers across the United States. PATIENTS A total of 1182 patients with a closed humeral shaft fracture initially managed nonoperatively with a functional brace from 2005 to 2015 were reviewed retrospectively from 9 institutions. INTERVENTION Functional brace. MAIN OUTCOME MEASUREMENTS Conversion to surgery. RESULTS A total of 344 fractures (29%) ultimately underwent surgical intervention. Reasons for conversion included nonunion (60%), malalignment beyond acceptable parameters (24%), inability to tolerate functional bracing (12%), and persistent signs of radial nerve palsy requiring exploration (3.7%). Univariate comparisons showed that females and whites were significantly (P < 0.05) more likely to be converted to surgery. The multivariate logistic regression identified females as being 1.7 times more likely and alcoholics to be 1.4 times more likely to be converted to surgery (P < 0.05). Proximal shaft as well as comminuted, segmental, and butterfly fractures were also linked to a higher rate of conversion. CONCLUSIONS This large multicenter study identified a 29% surgical conversion rate, with nonunion as the most common reason for surgical intervention after the failure of functional brace. These results are markedly different than previously reported. These results may be helpful in the future when counseling patients on the choice between functional bracing and surgical intervention in managing humeral shaft fractures.

Abstract
BACKGROUND It is unclear if clinical recovery following a midshaft clavicle fracture can accurately predict fracture-healing. The additional information that can be assessed at 6 weeks after injury may have superior predictive value compared with information available at the time of the injury. METHODS A prospective study of all patients (≥16 years of age) who sustained a fully displaced midshaft clavicle fracture was performed. We assessed patient demographic characteristics, injury factors, functional scores, and radiographic predictors with a standardized protocol at 6 weeks. Conditional stepwise regression modeling was used to assess which factors independently predicted nonunion at 6 months after the injury as determined by computed tomography (CT). The nonunion predictor 6-week model was compared with a previously validated model based on factors available at the time of the injury, which included smoking, comminution, and fracture displacement. RESULTS At 6 months, 200 patients completed follow-up. The CT-defined nonunion rate was 14% (27 of 200). Of the functional scores, the QuickDASH (the abbreviated version of the Disabilities of the Arm, Shoulder and Hand questionnaire) had the highest accuracy on receiver operator characteristic (ROC) curve analysis with a 39.8-point threshold, above which was associated with nonunion (area under curve [AUC], 76.8%; p < 0.001). Sixty-nine percent of the cohort had a QuickDASH score of <40 points at 6 weeks, and 95% (131 of 138) of these patients had fracture union. On regression modeling, a QuickDASH score of ≥40 points (p = 0.001), no callus on radiographs (p = 0.004), and fracture movement on examination (p = 0.001) were significant predictors of nonunion. If none were present, the predicted nonunion risk was 3%, found in 40% (80 of 200) of the cohort. Conversely, if ≥2 of the predictors were present, found in 23.5% of the cohort, the predicted nonunion risk was 60%. The nonunion predictor model at 6 weeks appeared to have superior accuracy (AUC, 87.3%) when compared with the nonunion predictor model at the time of injury (AUC, 64.8%) for fracture-healing on ROC curve analysis. CONCLUSIONS Delayed assessment at 6 weeks following displaced midshaft clavicle fracture enables an accurate prediction of patients who are likely to have union with nonoperative management. One in 4 patients are at an increased risk of nonunion and may benefit from operative intervention. LEVEL OF EVIDENCE Prognostic Level I.

Abstract
BACKGROUND Humeral shaft nonunions are challenging to treat, and those that require >1 surgical procedure in order for a nonunion to heal are termed recalcitrant. Most studies on nonunion have evaluated the union rate independent of the number of procedures required to achieve union. The aims of the present study were (1) to compare the healing rates after the index operation for the treatment of a nonunion with conventional versus locked plating with or without graft augmentation, (2) to report the prevalence of recalcitrant nonunion, and (3) to identify risk factors that predict a recalcitrant nonunion. METHODS We performed a retrospective analysis of a prospectively collected database of 125 humeral shaft nonunions treated with open reduction and plate fixation by a single surgeon over 25 years. Univariate and multivariate regression analyses were performed to compare healing rates by type of plate fixation and biological augmentation and to identify demographic, injury, and treatment-related risk factors for the development of a recalcitrant nonunion. RESULTS One hundred and five patients (84%) had healing after the index procedure for the treatment of nonunion. Twenty patients (16.0%) required secondary procedures and were defined as having a recalcitrant nonunion. Eight of these patients (6.4% of the overall group) healed after the secondary interventions, and 12 (9.6% of the overall group) had a failure to unite. There were no significant differences in healing rates between conventional and locked plates or between the types of bone graft (autogenous or recombinant human bone morphogenetic protein). Risk factors for the development of a recalcitrant nonunion were plate fixation of the acute humeral fracture, a history of deep infection, and ≥2 prior procedures. CONCLUSIONS Plate fixation with bone graft augmentation remains a successful method for the treatment of humeral shaft nonunions. Neither plate type nor graft type reduced the risk of a recalcitrant nonunion. Factors that predicted a recalcitrant nonunion were operative fixation of the acute fracture with a plate, a history of deep infection, and ≥2 surgical procedures.

Scoring of radiographic cortical healing with the radiographic humerus union measurement predicts union in humeral shaft fractures. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2020; 30:835-838. [PMID: 32034464 DOI: 10.1007/s00590-020-02635-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/01/2019] [Accepted: 01/27/2020] [Indexed: 10/25/2022]
Abstract
PURPOSE The purpose of this study is to determine if the radiographic humerus union measurement (RHUM) is predictive of union in humeral shaft fractures treated nonoperatively. METHODS All patients with long bone fracture nonunion presenting to a single surgeon were enrolled in a prospective registry. This registry was queried to identify patients with humeral shaft fractures treated nonoperatively and developed nonunion. The nonunion cohort was matched to a three to one gender- and age-matched control group that were treated nonoperatively for a humeral shaft fracture and achieved union. Two fellowship-trained orthopedic traumatologists blinded to eventual union scored radiographs obtained 12 weeks after injury using the RHUM. A binomial logistic regression determined the effect of the RHUM on the likelihood of developing union. RESULTS Nine patients with humeral shaft fractures treated nonoperatively with radiographs 12 weeks after injury that developed nonunion were identified. These patients were matched to 27 controls. Logistic regression demonstrated the RHUM was a significant predictor of healing 12 weeks after humeral shaft fracture treated nonoperatively (p = 0.014, odds ratio 9.434, 95% CI for OR 1.586-56.098). All patients with RHUM below 7 went on to nonunion. All patients with RHUM above 8 healed. Three of seven patients (43%) with RHUM of 7 or 8 healed. CONCLUSION The RHUM demonstrated an increased likelihood of achieving union 12 weeks after injury. Orthopedic surgeons can counsel patients that fractures with RHUM scores of 6 or below are in danger of developing nonunion and can target interventions appropriately.
