Clinical outcomes of non-COVID-19 orthopaedic patients admitted during the COVID-19 pandemic: a multi-centre interrupted time series analysis across hospitals in six different countries. BMJ Open 2023; 13:e073276. [PMID: 37666551 PMCID: PMC10481718 DOI: 10.1136/bmjopen-2023-073276] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Accepted: 08/16/2023] [Indexed: 09/06/2023] Open
Abstract
OBJECTIVES To assess across seven hospitals from six different countries the extent to which the COVID-19 pandemic affected the volumes of orthopaedic hospital admissions and patient outcomes for non-COVID-19 patients admitted for orthopaedic care. DESIGN A multi-centre interrupted time series (ITS) analysis. SETTING Seven hospitals from six countries who collaborated within the Global Health Data@Work collaborative. PARTICIPANTS Non-COVID-19 patients admitted for orthopaedic care during the pre-pandemic (January/2018-February/2020) and COVID-19 pandemic (March/2020-June/2021) period. Admissions were categorised as: (1) acute admissions (lower limb fractures/neck of femur fractures/pathological fractures/joint dislocations/upper limb fractures); (2) subacute admissions (bone cancer); (3) elective admissions (osteoarthritis). OUTCOME MEASURES Monthly observed versus expected ratios (O/E) were calculated for in-hospital mortality, long (upper-decile) length-of-stay and hospital readmissions, with expected rates calculated based on case-mix. An ITS design was used to estimate the change in level and/or trend of the monthly O/E ratio by comparing the COVID-19 pandemic with the pre-pandemic period. RESULTS 69 221 (pre-pandemic) and 22 940 (COVID-19 pandemic) non-COVID-19 orthopaedic patient admissions were included. Admission volumes were reduced during the COVID-19 pandemic for all admission categories (range: 33%-45%), with more complex patients treated as shown by higher percentages of patients admitted with ≥1 comorbidity (53.8% versus 49.8%, p<0.001). The COVID-19 pandemic was not associated with significant changes in patient outcomes for most diagnostic groups. Only for patients diagnosed with pathological fractures (pre-pandemic n=1671 and pandemic n=749), the COVID-19 pandemic was significantly associated with an immediate mortality reduction (level change of -77.7%, 95% CI -127.9% to -25.7%) and for lower limb fracture patients (pre-pandemic n=9898 and pandemic n=3307) with a significantly reduced trend in readmissions (trend change of -6.3% per month, 95% CI -11.0% to -1.6%). CONCLUSIONS Acute, subacute, as well as elective orthopaedic hospital admissions volumes were reduced in all global participating hospitals during the COVID-19 pandemic, while overall patient outcomes for most admitted non-COVID-19 patients remained the same despite the strain caused by the surge of COVID-19 patients.

Abstract
BACKGROUND Clavicle fractures are traditionally treated non-operatively. This study determines the functional outcome of midshaft clavicle fractures treated non-operatively, the factors influencing it, and the incidence of acromioclavicular joint (ACJ) arthrosis. METHODS Patients with midshaft clavicular fractures treated non-operatively between 16 and 50 years old with no prior AC joint problems were assessed. Demographics, hand dominance, type of occupation, and smoking status were documented. Functional scoring using DASH score, CM score, and radiological evaluation was done with special tests to diagnose AC joint arthrosis. Two or more positive special tests were considered significant for this study. RESULTS 101 patients were recruited, 83 male and 18 female patients. The average age of 34.7 ± 13.93 years. The average follow-up was 32.7 months (range: 24-75; SD ± 9.9 months). 48.5% were blue-collar workers, and 60.4% involved the dominant upper limb. 44.6% were cigarette smokers. There was 20 mm and more shortening in 21.8% of subjects. 40.6% had a significant special test, and 36.6% had radiological changes of AC joint osteoarthritis. Positive two or more special tests were significantly associated with radiological evidence of arthrosis (p = .00). The mean DASH score was 28.28 ± 17.4, and the mean CM score was 27.58 ± 14.34. Most have satisfactory to excellent scores. Hand dominance, smoking, and blue-collar work were significantly associated with poorer CM scores, and hand dominance was significant for Dash scores. CONCLUSION There is an equal distribution poor, satisfactory and excellent functional outcomes in patients with midshaft clavicle fractures treated non-operatively. The poor outcomes may be attributed to ACJ arthrosis. Hand dominance, smoking and blue-collar work affected the functional outcome. Shortening of the clavicle had no bearing on the clinical and radiological findings of osteoarthritis and functional scores. The presence of two or more positive special tests is an accurate predictor of AC joint arthritis.

Abstract
OBJECTIVE To provide an overview and approach to common nail bed injuries seen by primary care practitioners. SOURCES OF INFORMATION An Ovid MEDLINE literature search was performed using search terms and studies were graded based on level of evidence. MAIN MESSAGE Nail trauma is common in primary care practice and requires proper and prompt treatment to avoid lasting effects on finger function and cosmesis. When presented with a fingernail injury, primary care physicians should perform a thorough physical examination to determine extent of injury; take a history to rule out notable risk factors; perform a comprehensive neurovascular examination to assess pulp capillary refill, to do a 2-point discrimination, and to compare with an uninjured digit; and evaluate range of motion. Clinical evaluation may require local anesthesia and a tourniquet. Nail bed trauma can present in different ways and includes subungual hematomas, distal phalanx fractures, Seymour fractures, and-in more severe cases-fragmentation or avulsion of the nail bed. Treatment for subungual hematomas where the nail plate is intact does not require nail plate removal and nail bed exploration; however, exploration and repair are indicated for a nail plate injury, a proximal fracture involving the germinal matrix, and a distal phalanx fracture requiring stabilization. CONCLUSION Fingertips are essential to normal hand function. Nail trauma is common and can be managed by primary care physicians. Shared decision making concerning management is based on the mechanism and extent of the injury and aims to prevent secondary deformities.

Abstract
OBJECTIVES Falls with fracture in hospitalised patients remain a common occurrence with significant morbidity and mortality. Our objectives were to determine the characteristics of patients who suffer falls with fractures in hospital, and to examine whether outcomes in this cohort differ from those of patients who fall without sustaining a fracture. METHODS Coding data pertaining to a 6-year period (2012-2017) were interrogated. Patients coded as having suffered a fall in hospital during this period were identified and divided into those who did and those who did not suffer fractures due to their fall. Patient demographics and comorbidities were compared between groups and outcome measures examined with descriptive statistics and binary logistic regression. RESULTS From 236,720 inpatient admissions, 721 falls were recorded, 128 of which were associated with a fracture. Delirium (30% in those who suffered a fracture vs. 21% in those who did not, p < 0.040), dementia (23% vs. 13%, p < 0.004), female sex (53% vs. 44%, p < 0.020) and older age (76.8 vs. 72.8 years, p < 0.010) were associated with falls with fractures in hospital. Falls with fractures were associated with a longer length of inpatient stay by 9.2 days (95% CI 5.5-12.9, p < 0.001) and were an independent predictor of inpatient mortality. CONCLUSIONS Greater understanding of characteristics of patients at risk of falls with fractures, as well as knowledge of the considerable associated morbidity and mortality, will help to prognosticate when these events occur and, potentially, to put preventative measures in place.

A Delphi consensus on the management of Spanish patients with osteoporosis at high risk of fracture: OSARIDELPHI study. Arch Osteoporos 2023; 18:110. [PMID: 37610481 PMCID: PMC10447260 DOI: 10.1007/s11657-023-01318-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Accepted: 08/07/2023] [Indexed: 08/24/2023]
Abstract
The OSARIDELPHI study evaluated the level of agreement between specialists in osteoporosis regarding the management of patients with high-risk fractures in Spain. The results provide expert-based recommendations for prevention, diagnosis, and treatment related to fracture risk. Therefore, the study facilitates clinical decision-making for managing this patient's profile. PURPOSE To evaluate the level of agreement between specialists in osteoporosis regarding the management of patients with high-risk fractures in Spain. METHODS A two-round Delphi study was performed using an online survey. In round 1, panel members rated their level of agreement with assessments on a 9-point Likert scale. Item selection was based on acceptance by ≥ 66.6% of panel experts and the agreement of the scientific committee. In round 2, the same panelists evaluated non-consensus items in round 1. RESULTS A total of 80 panelists participated in round 1; of these, 78 completed the round 2 survey. In round 1, 122 items from 4 dimensions (definition of fracture risk: 11 items, prevention and diagnosis: 38 items, choice of treatment: 24 items, and treatment-associated quality of life: 49 items) were evaluated. The consensus was reached for 90 items (73.8%). Panelists agreed that categorizing high risk, very high risk, or imminent risk determines secondary prevention actions (97.5%). Experts agreed that treatment with bone-forming drugs should be considered in case of a very high risk of fracture, and a sequential change to antiresorptive drugs should be made after 1-2 years (97.5%). Panelists also recommended corrective action plans for non-adherent patients to improve adherence (97.5%). A total of 131 items were finally accepted after round 2. CONCLUSION This Delphi study provides expert-based recommendations on clinical decision-making for managing patients with osteoporosis at high risk of fracture.

Abstract
Fracture-related infection is a serious complication which can occur following musculoskeletal injury and is associated with significant morbidity. These complications can be challenging to recognise, and experts have provided a clearer definition of fracture-related infection to help with the diagnosis and detection of these infections. This system includes clinical, radiological and laboratory-based diagnostic features which are either confirmatory or suggestive of fracture-related infection. Treatment requires a multifaceted approach with multidisciplinary involvement, and generally a combination of surgical techniques and prolonged antibiotics, the timing and choice of which should be optimised. This article provides an evidence-based review of the British Orthopaedic Association Standards for Trauma for the diagnosis and management of fracture-related infections.

Abstract
Low-intensity pulsed ultrasound treatment is known to shorten the healing period of bone fractures by 30%-40%, but the initial mechanism of the healing process remains unknown. One possible mechanism is related to the piezoelectricity of bone. However, the complex geometry of bones results in inherent challenges to evaluating electric fields induced therein. Therefore, in this study, we investigate the piezoelectric responses of bones by using simulations to study the wave propagation and induced potentials in bone, according to the piezoelectric finite-difference time-domain (PE-FDTD) method. First, we verify the suitability of the PE-FDTD method by comparing the simulated electric field results with the experimental data obtained by an ultrasound receiver using bone as the piezoelectric element. Next, ultrasound irradiation into a real bone model (the radius of a 66-year-old woman) is simulated at different incident angles. At normal incidence and off-axis incidence (45°), the maximum electric field strength was 4.3 and 5.6 mV/cm, respectively. We also present evidence of significant shear wave contribution to the induced potential. The results of this study confirm the existence of ultrasonically induced potentials in heterogenous bones with complex shapes, equal in magnitude to potentials generated in electrically stimulated bone healing.

Abstract
BACKGROUND San Diego County hospitals commonly care for patients injured by falls from the United States-Mexico border. From 2018 to 2019, the height of >400 miles of an existing border wall was raised. Prior work has demonstrated a 5-fold increase in traumatic border wall fall injuries after barrier expansion. We aimed to examine the impact of a barrier height increase on fracture burden and resource use. METHODS We performed a retrospective review of patients admitted to a level 1 trauma center from 2016 to 2021 with lower extremity or pelvic fractures sustained from a border wall fall. We defined the pre-wall group as patients admitted from 2016 to 2018 and the post-wall group as those admitted from 2019 to 2021. We collected demographic and treatment data, hospital charges, weight-bearing status at discharge, and follow-up. RESULTS A total of 320 patients (pre-wall: 45; post-wall: 275) were admitted with 951 lower extremity fractures (pre-wall: 101; post-wall: 850) due to border wall fall. Hospital resources were utilized to a greater extent post-wall: a 537% increase in hospital days, a 776% increase in intensive care unit days, and a 468% increase in operative procedures. Overall, 86% of patients were non-weight-bearing on at least 1 lower extremity at discharge; 82% were lost to follow-up. CONCLUSION Traumatic lower extremity fractures sustained from border wall fall rapidly rose after the wall height increase. Hospital resources were used to a greater extent. Patients were frequently discharged with weight-bearing limitations and rarely received scheduled follow-up care. Policymakers should consider the costs of caring for border fall patients, and access to follow-up should be expanded.

Abstract
BACKGROUND There is a lack of detailed epidemiological studies of finger fractures, the most common fracture of the upper extremity. METHODS Based on data of 21 341 finger fractures in the Swedish Fracture register, a national quality registry that collects data on all fractures, this study describes anatomical distribution, cause, treatment, age distribution, and result in terms of patient related outcome measures (PROMs). RESULTS The most common finger fracture was of the base of the 5th finger, followed by the distal phalanx in the 4th finger. Open fractures were most common in the distal phalanges, especially in the 3rd finger. Intraarticular fractures were most frequent in the middle phalanges. Fall accidents was the most common cause of a fracture. The mean age at injury was 40 years (38 for men, 43 for women). 86% of finger fractures in adults were treated non-operatively. Men were more frequently operated than women. Finger fractures did not affect hand function or quality of life and there were no relevant differences in PROMs between fracture type, treatment, or sex. CONCLUSION This study presents detailed information about the various types of finger fractures which can be used as point of reference in clinical work and for future studies.

Abstract
We present an unusual case of ruptured subclavian artery pseudoaneurysm following hydrotherapy and shoulder massage session on a background of clavicle non-union.Following a clavicle fracture 16 years ago, which was managed conservatively, a woman in her 30s presents over a decade later with a ruptured subclavian artery pseudoaneurysm.The original midshaft clavicle fracture was sustained 16 years ago. Conservative management was agreed, and she was discharged. Six years ago, she developed a small subclavian artery pseudoaneurysm which was kept under surveillance for 12 months with no active intervention required.Over the following years, she continued to have intermittent shoulder girdle discomfort and neuropathic symptoms. On this presentation, after a sports massage, she presented with rapid-onset supraclavicular and axillary swelling. This was diagnosed as a ruptured subclavian artery pseudoaneurysm and was treated with emergency radiological-guided stenting and subsequent internal fixation of the clavicle non-union.The patient then attended regular orthopaedic and vascular follow-up to ensure her clavicle fracture unites and the graft remains patent.We discuss the case presentation and management of this unusual injury.

Abstract
CASE Distal phalangeal fractures are often treated conservatively. However, some patients experience residual pain. We report 2 cases of patients who underwent low-intensity pulsed ultrasound (LIPUS) therapy for pseudarthrosis after fracture of the distal phalanx of the fifth toe with symphalangism. Both patients (female, 63 and 33-year-old, respectively) underwent conservative treatment with buddy-taping fixation; however, bone union failed, and LIPUS therapy was initiated. In both cases, bone union was achieved and pain resolved after 3 months. CONCLUSION Bone union occasionally fails after conservative treatment of distal phalangeal fractures. LIPUS is a useful treatment of symptomatic pseudarthrosis after such fractures.

Abstract
BACKGROUND Reasonable functional outcomes for nonoperative management of isolated, closed fifth metacarpal neck fractures with up to 70° angulation have been reported; however, reported outcomes for fractures with greater than 70° angulation are limited. This study describes clinical outcomes of nonsurgically treated fifth metacarpal neck fractures with angulation of greater than 70°. METHODS A retrospective review of patients treated between May 1, 2016, and May 1, 2020, included: (1) patients aged 18 years and above with an isolated, closed, fifth metacarpal neck fracture; (2) nonsurgical treatment; (3) healed fractures with angulation greater than 70° measured on oblique radiographs; and (4) minimum 6-month follow-up after injury. Photographic hand motion and patient-rated outcomes (Functional Hand Scale, Quick Disabilities of the Arm, Shoulder, and Hand [QuickDASH], 12-item Short-Form Health Survey [SF-12]) were collected and reported. RESULTS A total of 364 fractures were identified; 11% (40/364) demonstrated angulation of greater than 70° (range: 71°-82°); and 15 patients (inclusion rate: 38%, 15/40) with mean fracture angulation of 73° (range: 71°-77°) participated in the study. Mean follow-up was 32 months (range: 8-120 months), the dominant hand was injured in 87% (13/15) of patients, and 47% (7/15) of patients worked in manual labor. All patients scored the highest rating of "very good" (range: 26-30 of 30 points) on the functional hand scale. A QuickDASH score of zero (no morbidity) was reported in 80% (12/15) of patients. About 87% (13/15) of patients had average or above-average scores on the SF-12 (mean = 109, range: 84-115). CONCLUSIONS Patients with healed, isolated, closed fifth metacarpal neck malunions with severe angulation greater than 70° demonstrated acceptable functional outcomes based on patient-rated outcomes scoring.

Abstract
The clinical efficacy of ESWT in treating bone non union has been widely recognized, but the biological mechanism of ESWT promoting bone non union healing is still unclear. ESWT can make old callus micro fracture through mechanical conduction, form subperiosteal hematoma, promote the release of bioactive factors, reactivate the fracture healing mechanism, rebalance the activities of osteoblasts and osteoclast, promote the angiogenesis of fracture site, and accelerate the healing of bone nonunion.Over recent years, great efforts have been made by both scientists and clinicians to explore the underlying mechanism behind the healing effect of ESWT on bone fractures. In this review, we introduced the growth factors during osteogenesis induced by ESWT hoping to provide new insights in the clinical use of ESWT.

Abstract
Pelvic-acetabular fractures lead to high mortality in elders and their association between different groups is not known. Our results indicate that older age with pelvic-acetabular fracture was significantly associated with mortality. This finding may help planning and allocating healthcare resources, risk stratification, and optimizing the treatment of pelvic fractures. PURPOSE Pelvic or acetabular fractures are among main outcomes of low-energy trauma such as falls, especially in older adults. They represent approximately 3-8% of all fractures and are associated with a high mortality rate ranging from 4 to 28%. This study is aimed at comparing the incidence and trends of hip fractures and pelvic-acetabular fractures in the Taiwanese general population, gender differences in adults aged over 65 years, and mortality risk between pelvic or acetabular fractures and hip fractures and surgery trends in patients with these fractures. METHODS A retrospective study was conducted extracting data from the National Health Insurance Research Database of patients diagnosed with hip fracture and pelvic acetabular fracture between 2000 and 2018. RESULTS Older age with pelvic-acetabular fracture was significantly associated with increased mortality. No significant differences were found in comorbidities between the two fracture groups. Results provide clear epidemiological evidence for trends in pelvic-acetabular fractures in Taiwan and demonstrate the need for better strategies to manage these fractures and comorbidities, particularly in older adults. CONCLUSION Findings of this study may aid in planning and allocating healthcare resources, risk stratification, and optimizing the treatment of pelvic fractures among older adults in Taiwan.

Abstract
Immune cells play an important functional role in bone fracture healing. Fracture repair is a well-choreographed process that takes approximately 21 days in healthy mice. While the process is complex, conceptually it can be divided into four overlapping stages: inflammation, cartilaginous callus formation, bony callus formation, and remodeling. T cells play a key role in both the cartilaginous and bony callus phases by producing IL-17A. In this issue of the JCI, Dar et al. showed that T cells were recruited from the gut, where the gut microbiota determined the pool of T cells that expressed IL-17A. Treatment with antibiotics and dysbiosis reduced the expansion of IL-17-expressing CD4+ T cells (Th17) and impaired callus formation. These findings demonstrate crosstalk among the gut microbiota, the adaptive immune system, and bone that has clinical implications for fracture healing.

Abstract
OBJECTIVES To compare hospital outcomes and late displacement between stress-positive minimally displaced lateral compression type 1 (LC1) pelvic ring injuries treated with combined anterior-posterior versus posterior-only fixation. DESIGN Retrospective comparative cohort. SETTING Urban level-one trauma center. PATIENTS/PARTICIPANTS LC1 injuries managed operatively. INTERVENTION Anterior-posterior versus posterior-only fixation. MAIN OUTCOME MEASUREMENTS Physical therapy (PT) clearance, discharge location, hospital length of stay (LOS), inpatient morphine equivalent doses (MED), and fracture displacement at follow-up. RESULTS Groups were similar in demographic and injury characteristics (age, high energy mechanism, ASA score, stress displacement, and rami/sacral fracture classifications). Anterior-posterior fixation resulted in longer operative times (median difference (MD): 27.0 minutes, 95% confidence interval (CI): 17.0 to 40.0, P < 0.0001) and had a trend of increased estimated blood loss (MD: 10 mL, CI: 0 to 30, P = 0.07). Patients with anterior-posterior fixation required less inpatient MEDs (MD: -180.0, CI: -341.2 to -15.0, P = 0.02), were more likely to clear PT by discharge (100% vs. 70%, proportional difference (PD): 30%, CI: 2.0%-57.2%, P = 0.02), were less likely to discharge to rehabilitation facilities (0% vs. 30%, PD: 30%, CI: 2.0%-57.2%, P = 0.02), and had a trend of less days to clear PT after surgery (MD: -1, CI: -2 to 0, P = 0.09) and decreased LOS (MD: -1, CI: -4 to 1, P = 0.17). Late fracture displacement did not differ between groups. CONCLUSION Anterior-posterior fixation of LC1 injuries was associated with an improved early hospital course-specifically, reduced inpatient opioid use and an increased number of patients who could clear PT and discharge home. LEVEL OF EVIDENCE Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
BACKGROUND This study aimed to review level I and II therapeutic studies on boxer's fractures to measure variation in quality among the highest level study designs. METHODS We used quantitative measures of study quality to evaluate prospective randomized controlled trials (RCTs) of treatments of boxer's fractures. A search of PubMed, using terms "boxer's fracture" and "fifth metacarpal neck fracture" identified 164 articles from 1961 to 2019. From this list, we identified 6 RCTs. Two observers classified each trial according to 3 systems: the Oxford Levels of Evidence, the modified Coleman Methodology Score, and the revised Consolidated Standards of Reporting Trials (CONSORT) score. RESULTS The 2 reviewers were consistent in their use of the Oxford Levels of Evidence (100% agreement). The differences between the average modified Coleman Methodology scores and the average CONSORT scores assigned by the 2 observers were not significant (46.2 vs 45.3 points, κ = 0) and (13.7 vs 14.3 points, κ = 0.33), respectively. Both observers rated all the studies as level I and as unsatisfactory according to the Coleman Methodology Score (100% and 100%), and less than half as unsatisfactory according to the CONSORT score (50% and 17%). Areas of deficiency included randomization, blinding, group comparability, clinical effect measurements, and allocation into treatment arms. CONCLUSION Classifying orthopedic scientific reports according to the levels of evidence implies a degree of respect for level I and II studies that may not always be merited. Our data suggest that the quality of higher level studies, namely those involving boxer's fractures, varies and may often be unsatisfactory when critically evaluated.

Abstract
BACKGROUND Bony remodeling of displaced clavicle fractures in adolescents remains poorly understood. PURPOSE To evaluate and quantify clavicle remodeling in a large population of adolescents with completely displaced fractures, which were treated nonoperatively, to better understand the factors that may influence this process. STUDY DESIGN Case series; Level of evidence, 4. METHODS Patients were identified from the databases of a multicenter study group investigating the functional outcomes of adolescent clavicle fractures. Patients between the ages of 10 and 19 years with completely displaced middiaphyseal clavicle fractures that were treated nonoperatively and who had further radiographic imaging of the affected clavicle at a minimum of 9 months from initial injury were included. Fracture shortening, superior displacement, and angulation were measured on the injury and final follow-up radiographs using previously validated techniques. Furthermore, fracture remodeling was classified as complete/near complete, moderate, or minimal, using an original classification system found to have good to excellent reliability (interobserver reliability = 0.78, intraobserver reliability = 0.90). Classifications were subsequently analyzed quantitatively and qualitatively to determine the factors associated with deformity correction. RESULTS Ninety-eight patients (mean age, 14.4 ± 2.0 years) were analyzed at a mean radiographic follow-up of 3.4 ± 2.3 years. Fracture shortening, superior displacement, and angulation significantly improved during the follow-up period by 61%, 61%, and 31%, respectively (P < .001). Furthermore, while 41% of the population had initial fracture shortening >20 mm at final follow-up, only 3% of the cohort had residual shortening >20 mm. Fracture remodeling was found to be associated with follow-up time; those with longer follow-up time demonstrated more remodeling (P = .001). Eighty-five percent of patients aged <14 years and 54% of patients aged ≥14 years at time of injury with a minimum follow-up of 4 years underwent complete/near-complete remodeling. CONCLUSION Significant bony remodeling occurs in adolescent patients with completely displaced clavicle fractures, including older adolescents, and appears to continue over longer time intervals, even beyond the adolescent years. This finding may help explain the low rate of symptomatic malunions in adolescents, even in severely displaced fractures, and particularly when compared with rates reported in adult studies.

Abstract
BACKGROUND Although pediatric hand fractures are common and generally have good outcomes, they remain a considerable source of anxiety for non-hand surgeons, who are less familiar with these injuries. We hypothesized that this anxiety may manifest as inefficiency in referral patterns. METHODS The records of pediatric patients with isolated, closed hand fractures without concurrent trauma seen at our institution by a hand surgeon between January 2017 and December 2018 were retrospectively reviewed. RESULTS There were 454 patients included; 62.1% were men, and the mean age was 9.6 years at initial encounter. Most patients (89.6%) were treated nonoperatively and incurred few complications (0.5%). Roughly half of all cases (n = 262) initially presented to an outside provider. Of these, 24.0% (n = 64 of 262) were evaluated by 2+ providers before a hand surgeon. Most commonly, these patients were referred from an outside emergency department (ED) to our ED before hand surgeon evaluation (n = 45 of 64). Forty-seven patients required surgery; however, none were performed urgently. Although a greater proportion of 7- to 11-year-old patients saw 2+ providers prior to a hand surgeon (P = .007), fewer required surgery (P < .001). CONCLUSIONS Pediatric closed hand fractures are mainly treated nonoperatively and nonemergently with generally excellent outcomes. Our data suggest that many patients continue to be referred through the ED or multiple EDs/providers for treatment. These inefficient referral patterns demonstrate the need for better education for ED and primary care providers, as well as better communication between these providers and local pediatric hand surgeons. Advancements in these areas are likely to improve efficiency of care and decrease costs.

Abstract
Treating osteoporosis and associated bone fractures remains challenging for drug development in part due to potential off-target side effects and the requirement for long-term treatment. Here, we identify recombinant adeno-associated virus (rAAV)-mediated gene therapy as a complementary approach to existing osteoporosis therapies, offering long-lasting targeting of multiple targets and/or previously undruggable intracellular non-enzymatic targets. Treatment with a bone-targeted rAAV carrying artificial microRNAs (miRNAs) silenced the expression of WNT antagonists, schnurri-3 (SHN3), and sclerostin (SOST), and enhanced WNT/β-catenin signaling, osteoblast function, and bone formation. A single systemic administration of rAAVs effectively reversed bone loss in both postmenopausal and senile osteoporosis. Moreover, the healing of bone fracture and critical-sized bone defects was also markedly improved by systemic injection or transplantation of AAV-bound allograft bone to the osteotomy sites. Collectively, our data demonstrate the clinical potential of bone-specific gene silencers to treat skeletal disorders of low bone mass and impaired fracture repair.

Abstract
INTRODUCTION Redeployment of orthopaedic consultants to a minor injuries unit (MIU) during the COVID-19 pandemic provided a unique opportunity to assess the impact of early senior specialist input on patient management. METHODS Patient demographics, diagnosis, location of injury and disposal method were compared between three 7-day periods: during the April 2020 COVID-19 lockdown (period A), one month prior to period A (period B) and one year prior to period A (period C). Orthopaedic consultants staffed the MIU during period A, and emergency nurse practitioners staffed the MIU during periods B and C. RESULTS Period A witnessed higher injury severity either due to modified activities or altered healthcare-seeking behaviour during lockdown. For fractures, compared with periods B and C, period A saw a lower rate of referral to fracture clinic (41% vs 100% vs 86%, p<0.001) and higher rate of discharge (38% vs 0% vs 9%, p<0.001). The median time to fracture clinic was also longer (15 days vs 6 days vs 10 days, p<0.001), indicating earlier institution of definitive care. There were no other significant differences between periods with radiology alerts and complaints received remaining largely unchanged. CONCLUSION Early senior orthopaedic input in the patient journey from MIU had clear benefits, this being most true for fracture diagnoses. Earlier definitive management planning was observed as lower rates of fracture clinic referral, higher rates of discharge and deferred first fracture clinic reviews. This study highlights the benefits of greater partnership between MIU and orthopaedics. As the pandemic subsides and redeployed staff return to normal duties, a modification of this model could be utilised to ensure this partnership is sustainable.
