Health-economic evaluation of orthogeriatric co-management for patients with forearm or humerus fractures: an analysis of insurance claims data from Germany.

Orthogeriatric co-management (OGCM) describes a collaboration of orthopedic surgeons and geriatricians for the treatment of fragility fractures in geriatric patients. While its cost-effectiveness for hip fractures has been widely investigated, research focusing on fractures of the upper extremities is lacking. Thus, we conducted a health economic evaluation of treatment in OGCM hospitals for forearm and humerus fractures.In a retrospective cohort study with nationwide health insurance claims data, we selected the first inpatient stay due to a forearm or humerus fracture in 2014-2018 either treated in hospitals that were able to offer OGCM (OGCM group) or not (non-OGCM group) and applied a 1-year follow-up. We included 31,557 cases with forearm (63.1% OGCM group) and 39,093 cases with humerus fractures (63.9% OGCM group) and balanced relevant covariates using entropy balancing. We investigated costs in different health sectors, length of stay, and cost-effectiveness regarding total cost per life year or fracture-free life year gained.In both fracture cohorts, initial hospital stay, inpatient stay, and total costs were higher in OGCM than in non-OGCM hospitals. For neither cohort nor effectiveness outcome, the probability that treatment in OGCM hospitals was cost-effective exceeded 95% for a willingness-to-pay of up to €150,000.We did not find distinct benefits of treatment in OGCM hospitals. Assigning cases to study groups on hospital-level and using life years and fracture-free life years, which might not adequately reflect the manifold ways these fractures affect the patients' health, as effectiveness outcomes, might have underestimated the effectiveness of treatment in OGCM hospitals.

Is casting of displaced paediatric distal forearm fractures non-inferior to reduction under general anaesthesia? Study protocol for a pragmatic, randomized, controlled non-inferiority multicentre trial (the casting trial).

BACKGROUND: Treatment of displaced distal forearm fractures in children has traditionally been closed reduction and pin fixation, although they might heal and remodel without surgery with no functional impairment. No randomized controlled trials have been published comparing the patient-reported functional outcome following non-surgical or surgical treatment of displaced paediatric distal forearm fractures. METHODS: A multicentre non-inferiority randomized controlled trial. Children aged 4-10 years with a displaced distal forearm fracture will be offered inclusion, if the on-duty orthopaedic surgeon finds indication for surgical intervention. They will be allocated equally to non-surgical treatment (intervention) or surgical treatment of surgeon's choice (comparator). Follow-up will be 4 weeks and 3, 6, and 12 months. The primary outcome is the between-group difference in 12 months QuickDASH score. We will need a sample of 40 patients to show a 15-point difference with 80% power. DISCUSSION: The results of this trial may change our understanding of the healing potential of paediatric distal forearm fractures. If non-inferiority of non-surgical treatment is shown, the results may contribute to a reduction in future surgeries on children, who in turn can be treated without the risks and psychological burdens associated with surgery.

The construct validity and internal consistency of QuickDASH in pediatric patients with upper extremity fractures.

BACKGROUND AND PURPOSE: Investigation of treatment options in the pediatric population necessitates the use of valid patient-reported outcome measures (PROMs). We aimed to assess the construct validity and internal consistency of the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) in the pediatric population with upper extremity fractures treated both operatively and conservatively. PATIENTS AND METHODS: QuickDASH, along with several reference PROMs and objective outcome measures, was obtained from 148 5- to 18-year-old patients with a humeral medial epicondyle fracture or a fracture of the distal forearm in a cross-sectional setting with a single follow-up visit. Spearman's rank correlation and linear regression models were used to assess convergent validity, exploratory factor analysis (EFA) to assess structural validity, and Cronbach's alpha to investigate internal consistency. RESULTS: The direction and magnitude of correlation showed by QuickDASH with reference outcome measures was consistent and demonstrated good convergent validity. EFA indicated a 3-factor model with poor fit indices and structural validity remained questionable. Construct validity was considered acceptable overall. QuickDASH demonstrated good internal consistency with an acceptable Cronbach's alpha (α = 0.75). CONCLUSION: QuickDASH demonstrated acceptable construct validity and good internal consistency and is thus a valid instrument, with some limitations, to assess disability and quality of life in pediatric patients with upper extremity fractures.

Regional Anesthesia as an Alternative to Procedural Sedation for Forearm Fracture Reductions in the Pediatric Emergency Department.

BACKGROUND: Pediatric forearm fractures are common injuries in the pediatric emergency department (PED). Pediatric procedural sedation (PPS) is often required for forearm fracture reductions and pain control for casting. Bier blocks and hematoma blocks are types of regional anesthesia (RA) procedures that can be performed as a potential alternative to PPS. OBJECTIVE: The objective of this study is to compare the safety of RA with that of PPS. We hypothesized that RA has a safety profile that is equal or superior to PPS as well as a shorter duration of treatment in the PED. METHODS: Pediatric emergency department encounters in patients presenting with a diagnosis of radius fracture, ulna fracture, distal "both-bone" fracture, Monteggia fracture, and/or Galeazzi fracture were included. Outcomes of interest included patient adverse events (AEs), sedation medications used, PED duration of treatment (arrival time to disposition time), sedation failures, and reduction failures. RESULTS: Propensity matching was performed resulting in 632 well-matched RA-PPS pairs. The PPS cohort had 13% of encounters with at least 1 AE compared with 0.2% in the RA cohort, P < 0.001. The most common AE in the PPS group was hypoxia (9.8%), and the only AE in the RA group was an intravenous infiltrate (0.16%). Within the matched cohorts, PPS required more medications than RA (100% vs 60%, P < 0.001). Ketamine alone was more commonly used in the PPS group than the RA group (86% vs 0.2%, P < 0.001). Propofol was used only in the PPS group. The average duration of treatment was 205 (SD, 81) minutes in the PPS group and 178 (SD, 75) minutes in the RA group ( P < 0.001). There were no reduction failures in either group. CONCLUSIONS: Bier blocks and hematoma blocks are an acceptable alternative to PPS for children requiring forearm reductions. The AE rate is low and the reduction success rate is high. Duration of treatment in the PED is shorter for patients receiving RA compared with PPS.

Treatment of delayed union of the forearm with extracorporeal shockwave therapy: a case report and literature review.

Compared to other long bones, forearm fractures are particularly challenging due to the high rate of complications. These include malunion, delayed/nonunion, wrist and elbow movement reduction, and pain. Surgical procedure is considered the gold standard for managing delayed union and nonunion of the long bones. However, in the last decades, extracorporeal shockwave therapy (ESWT) has emerged as an effective and less invasive approach to enhance bone regeneration and fracture healing, avoiding major complications of surgical procedures. In contrast to the broad literature reporting good clinical results of ESWT in the treatment of nonunions, there is currently limited evidence regarding the clinical application of shock waves on long bone delayed fractures, particularly those of the forearm. In the present paper, we report a case of delayed bone healing of the diaphyseal region of the ulna treated with focused ESWT. The successful case experienced bone healing at the fracture site in less than 3 months after initial ESWT treatment. Acknowledging the limitation of reporting a case report, however, the remarkable clinical results and the absence of side effects contribute valuable information in support of the use of ESWT as an effective alternative to standard surgery for forearm fractures.

Forearm fractures - are we counting them all? An attempt to identify and include the missing fractures treated in primary care.

OBJECTIVE: Norway has a high incidence of forearm fractures, however, the incidence rates based on secondary care registers can be underestimated, as some fractures are treated exclusively in primary care. We estimated the proportion of forearm fracture diagnoses registered exclusively in primary care and assessed the agreement between diagnosis for forearm fractures in primary and secondary care. DESIGN: Quality assurance study combining nationwide data from 2008 to 2019 on forearm fractures registered in primary care (Norwegian Control and Payment of Health Reimbursement) and secondary care (the Norwegian Patient Registry). SETTING AND PATIENTS: Forearm fracture diagnoses in patients aged ≥20 treated in primary care (n = 83,357) were combined with injury diagnoses for in- and outpatients in secondary care (n = 3,294,336). MAIN OUTCOME MEASURES: Proportion of forearm fractures registered exclusively in primary care, and corresponding injury diagnoses for those registered in both primary and secondary care. RESULTS: Of 189,105 forearm fracture registrations in primary and secondary care, 13,948 (7.4%) were registered exclusively in primary care. The proportion ranged from 4.9% to 13.5% on average between counties, but was higher in some municipalities (>30%). Of 66,747 primary care forearm fractures registered with a diagnosis in secondary care, 62% were incident forearm fractures, 28% follow-up controls, and 10% other fractures or non-fracture injuries. CONCLUSION: An overall small proportion of forearm fractures were registered only in primary care, but it was larger in some areas of Norway. Failing to include fractures exclusively treated in primary care could underestimate the incidence rates in these areas.

Norwegian forearm fracture incidence based on secondary care may be underestimated by not including fractures treated exclusively in primary care.The mean proportion of forearm fractures exclusively handled in primary care is 7% and varies from 5% to 14% between counties.Fractures treated in primary care can be considered for more accurate national incidence rates. Correct fracture diagnosis needs further investigation.

Prescribing braces after forearm fractures does not decrease refracture rate.

Refracture is one of the most common complications of pediatric forearm fractures. One way to decrease this risk is to extend immobilization with a brace after the cast has been removed to allow for a range of motion exercises. The purpose of this study was to examine whether prescribing a brace after casting was discontinued decreased the risk of refracture. A retrospective, cohort study was performed at one level I trauma center. Girls under 10 years and boys under 12 years who sustained a forearm fracture from January 2013 to December 2018 were included. Patients with open fractures, fractures that required operative intervention, fractures involving the physis, fracture-dislocations, floating elbows, fractures in children with endocrine abnormalities, and fractures in patients lost to follow-up were excluded. The primary endpoint was a refracture within 6 months of the original injury that extended through the original fracture site. In total 2093 patients met the inclusion criteria. There were 19 refractures (0.9%). There was no statistically significant difference in the refracture rate between the braced (11/1091) and unbraced (8/1002) cohorts (Fisher exact value 0.65 at P < 0.05). The most common fracture type that went on to refracture was greenstick fractures. This large, retrospective study aimed to examine whether prescribing a brace had any significant effect on the refracture rate. Bracing after the cast is removed may help ease family anxiety and extend the period of immobilization while allowing for hygiene and range of motion, but it does not significantly decrease the rate of refracture.

A Narrative Review of the Uses of Ultrasound in the Evaluation, Analgesia, and Treatment of Distal Forearm Fractures.

BACKGROUND: Distal forearm fractures are a commonly encountered injury in the emergency department (ED), accounting for 500,000 to 1.5 million visits and 17% of ED fractures. The evaluation and management of these fractures frequently employs x-ray studies, conscious sedation, closed reduction, and splinting. Point-of-care ultrasound (POCUS) can offer significant benefit in the diagnosis and management of these common injuries. OBJECTIVE OF THE REVIEW: To review the clinical utility of POCUS in the diagnosis of distal forearm fractures, as well as to demonstrate the performance of ultrasound-guided analgesia delivery and ultrasound-guided reduction technique. DISCUSSION: The initial evaluation of forearm injuries frequently includes x-ray studies. However, multiple studies have shown ultrasound to be sensitive and specific for distal radius fractures, with the added value of detecting soft tissue injuries missed by conventional radiography. POCUS may also facilitate analgesia through the use of ultrasound-guided hematoma blocks, which removes the need for conscious sedation prior to manipulation. Finally, POCUS can be used after manipulation to assess cortical realignment of the bone fragments and spare the patient multiple reduction attempts and repeat radiographs. CONCLUSION: Distal forearm fractures are common, and the emergency physician should be adept with the evaluation and management of these injuries. POCUS can be a reliable modality in the detection of these fractures and can be used to facilitate analgesia and augment success of reduction attempts. These techniques may decrease length of stay, improve patient pain, and decrease reduction attempts.

Paediatric forearm fractures: assessment and initial management.

The forearm is the most common site of fracture in children. At the time of initial assessment, a thorough examination and neurovascular assessment of the limb is necessary. X-rays allow evaluation of the fracture location and type, in addition to the degree of displacement. With the help of intranasal opiates, manipulation of fracture fragments can be performed in the emergency department. Immobilisation in plaster is the gold standard treatment for paediatric forearm fractures where the degree of displacement is within acceptable parameters. Manipulation and casting should be followed by orthogonal radiographs and a repeated neurovascular assessment of the limb. Oral analgesia and safety netting information should be provided on discharge and the child should be reviewed in fracture clinic within a week of the injury. This article reviews the British Orthopaedic Association Standards for Trauma and Orthopaedics for the early management of paediatric forearm fractures that do not require operative management.

Treatment Choice of Complete Distal Forearm Fractures in 8 to 14 Years Old Children.

BACKGROUND: New surgical techniques have challenged traditional guidelines for nonsurgical treatment in pediatric and adolescent distal forearm fractures. This study was performed to compare outcomes and costs between closed reduction with percutaneous pinning (CRPP) and closed reduction with casting in the treatment of complete distal forearm fractures in children 8 to 14 years old. METHODS: A retrospective cohort study was performed of 175 displaced distal forearm fractures treated with 2 different methods in the emergency department of a children's trauma center. One hundred and fourteen children were managed using CRPP. The remaining 61 were treated with closed reduction and casting. All patients had initial follow-up radiographs. The quality of reduction and the residual angulation in both the coronal and sagittal planes were recorded. Outcomes included the angulation after reduction, residual angulation at final follow-up, radiation exposure, total immobilization time, days absent from school, total costs, and postoperative complications. RESULTS: The postreduction sagittal plane angulation was significantly lower in the CRPP group (P=0.037). While residual deformity between the groups at the 6-month final follow-up was not significantly different in either the sagittal or coronal planes (P=0.486, 0.726), patients in the nonoperative group received greater radiation than those in the operative group (P<0.001). Patients in the nonoperative group missed fewer classes and sustained lower costs (P<0.001, <0.001). The mean immobilization time in each group was not significantly different (31.4±4.4 vs. 32.8±5.9 d; P=0.227). CONCLUSIONS: Although the postreduction quality was a little better and radiation exposure was less in the CRPP group, there was no difference between the 2 groups in angulation, total immobilization time, or complication rates after 6 months. The cost and time absent from school of patients in the nonoperative group was significantly lower than in the operative group. There is no clear advantage to CRPP treatment on outcomes. Therefore, closed reduction and casting is recommended in complete distal forearm fractures of children 8 to 14 years old. LEVEL OF EVIDENCE: Level III-therapeutic study.

Accuracy of point-of-care ultrasound for determining the adequacy of pediatric forearm fracture reductions.

BACKGROUND: The objective of the present study was to the determine the accuracy of point-of-care ultrasound (POCUS) in assessing closed reduction (CR) of pediatric forearm fractures in a pediatric emergency setting. METHODS: After determination of the need for CR using X-ray images by an orthopedic consultant, POCUS examinations were performed just before and after the reduction attempt. The transducer was positioned longitudinally over the dorsal, volar, and lateral surfaces of the radius and ulna to view the fracture site. The presence of angulation, displacement, or bayonetting of the fracture fragments was recorded. The adequacy of realignment according to the POCUS and the orthopedic consultant's final determination were recorded. RESULTS: Sixty-two patients were enrolled in the study and 96 bones were evaluated. The sensitivity and specificity of POCUS for adequacy of CR were 95.8% [95% confidence interval (CI): 88.3-99.1)] and 95.8% (95% CI: 78.8-99.8), the positive predictive value was 98.5% (95% CI: 91.0-99.7), and the negative predictive value was 88.4% (95% CI: 71.6-95.8). The corresponding positive and negative likelihood ratios were 23 (3.37-156.77) and 0.04 (0.01-0.12). There was high agreement between POCUS and X-ray images for predicting adequacy of CR [κ: 0.892 (±0.053)]. There was also a significant correlation between POCUS and X-ray measurements of angulation and displacement performed before and after CR, respectively (p < 0.001). CONCLUSION: Our study has reported the successful use of POCUS for the management of pediatric forearm fractures in a pediatric emergency department. Point-of-care ultrasound can minimize radiation exposure and appears to be an alternative and accurate tool for reduction attempts.

Traumatic Rupture of the Flexor Carpi Ulnaris Muscle Belly in a Circus Rigger.

Closed traumatic rupture of forearm flexor muscles has been reported rarely. Previous reports have included ruptures of the flexor digitorum profundus, flexor digitorum superficialis, flexor pollicis longus, flexor carpi radialis, pronator quadratus and the palmaris longus. We report a patient with a closed traumatic rupture through the muscle belly of the flexor carpi ulnaris and summarise the published literature on ruptures involving the forearm flexor muscles. Overall, conservative treatment can result in excellent outcomes. Early surgical intervention is recommended in patients with nerve involvement and compartment syndrome and delayed reconstruction may be considered for patients with functional deficits.

Below-elbow cast sufficient for treatment of minimally displaced metaphyseal both-bone fractures of the distal forearm in children: long-term results of a randomized controlled multicenter trial.

Background and purpose - We have previously shown that children with minimally displaced metaphyseal both-bone forearm fractures, who were treated with a below-elbow cast (BEC) instead of an above-elbow cast (AEC), experienced more comfort, less interference in daily activities, and similar functional outcomes at 7 months' follow-up (FU). This study evaluates outcomes at 7 years' follow-up.Patients and methods - A secondary analysis was performed of the 7 years' follow-up data from our RCT. Primary outcome was loss of forearm rotation compared with the contralateral forearm. Secondary outcomes were patient-reported outcome measures (PROMs) consisting of the ABILHAND-kids and the DASH questionnaire, grip strength, radiological assessment, and cosmetic appearance.Results - The mean length of FU was 7.3 years (5.9-8.7). Of the initial 66 children who were included in the RCT, 51 children were evaluated at long-term FU. Loss of forearm rotation and secondary outcomes were similar in the 2 treatment groups.Interpretation - We suggest that children with minimally displaced metaphyseal both-bone forearm fractures should be treated with a below-elbow cast.

Short and long-arm fiberglass cast immobilization for displaced distal forearm fractures in children: a randomized controlled trial.

PURPOSE: The aim of this study was to investigate whether short-arm fiberglass cast (SAC) immobilization provides fracture stabilization comparable to that of long-arm cast (LAC) treatment of displaced distal forearm fractures after closed reduction in paediatric patients. METHODS: A prospective, randomized, controlled trial of children aged four to 16 years (mean 9.9 years) was designed with a sample of 120 children, whose size was set a priori, with 60 treated with SAC and 60 with LAC. The primary outcome was fracture stability and rate of loss of reduction. The secondary outcome analysis evaluated duration of analgesic therapy, restriction in activities of daily life, and the duration until patients regained normal range of motion in the elbow. RESULTS: No statistically significant differences were found between the two groups in loss of reduction or duration of analgesic therapy. In contrast, the duration until normal range of motion in the elbow was regained was significantly longer in the LAC group (median 4.5 days, P < 0.001). Restriction in activities of daily life did not differ significantly between the two groups except for the item "help needed with showering in the first days after trauma" (SAC 60%, LAC 87%, P = 0.001). CONCLUSION: Fracture immobilization with short-arm fiberglass cast in reduced distal forearm fractures is not inferior to long-arm casts in children four years and older, excluding completely displaced fractures. Furthermore, short-arm casting reduces the need for assistance during showering. TRIAL REGISTRATION: NCT03297047, September 29, 2017.

Buckled, bent or broken? A guide to paediatric forearm fractures.

BACKGROUND: The radius and ulna are the most commonly fractured long bones in the school-aged population, accounting for 40% of all fractures. Management of individual fractures depends on the fracture pattern and age of the child. OBJECTIVE: The aim of this article is to provide an overview of the management concepts for specific fracture patterns and support general practitioners to confidently manage these fractures and refer to orthopaedic services when required. DISCUSSION: Orthopaedic advice and/or referral are recommended for unstable fracture types (greenstick and complete fractures), particularly in older children where remodelling potential is minimal. Early referral for growth plate injuries and suspected Monteggia and Galeazzi injuries is warranted to minimise long term complications.

The Management of Pediatric Open Forearm Fractures.

Open pediatric forearm fractures are common injuries that present to emergency departments across the United States. A total of 32% to 80% of all open pediatric fractures involve the forearm. Standard treatment for these injuries includes prompt intravenous antibiotic administration, tetanus prophylaxis, and usually bedside irrigation as a temporizing measure. Gustilo and Anderson type 2 and 3 open pediatric forearm fractures are generally managed with formal irrigation and debridement and fracture stabilization in the operating room. Management of Gustilo and Anderson type 1 open pediatric forearm fractures is not standardized, and level I evidence is currently lacking. Based on the existing data available, early antibiotic administration, bedside irrigation, and fracture stabilization in the emergency department may be a safe and effective initial treatment for these injuries, conferring a low risk for subsequent infection.

Utility of Postreduction Radiographs After Fluoroscopy-Guided Reduction and Casting of Uncomplicated Pediatric Forearm Fractures.

OBJECTIVE: The aim of the study was to determine efficacy of performing postreduction radiographs in managing uncomplicated pediatric forearm fractures after reduction and casting under fluoroscopic guidance. DESIGN: This is retrospective analysis of consecutive cases. SETTING: The study was conducted in a large urban hospital pediatric emergency department (ED). PARTICIPANTS: Pediatric patients presenting to the ED with a forearm fracture between the ages of 0 to 18 years. All received orthopedic manual reduction with fluoroscopic guidance and casting, then followed by performance of a dedicated 2-view radiographic series of postreduction forearm to document proper alignment and cast placement. MAIN OUTCOME(S) AND MEASURE(S): Of 236 consecutive cases studied, there were only 5 cases (2%) in which the managing orthopedist determined that a further reduction attempt was warranted based on the postreduction radiograph results. All were mid-shaft fractures of both radius and ulna, which were angulated and/or displaced. The remaining 231 patients with an uncomplicated forearm fracture received no further ED clinical orthopedic intervention after performing postreduction radiographs. The mean ED time to ultimate discharge was prolonged an average of 89 minutes per patient after reduction and casting while awaiting performance/orthopedic review of postreduction radiographs. A calculation of postreduction radiograph cost amounted to a total of nearly US $50,000. CONCLUSIONS: Performance of postreduction radiographs in children with uncomplicated pediatric forearm fractures that are reduced and casted under fluoroscopy has little clinical utility and contributes to increased radiation exposure, patient health care cost, and time spent in the ED. Patients with mid-shaft forearm fractures involving both radius and ulna (especially if angulated or displaced) are at risk for unacceptable reduction after casting and may be the target group in which performing post reduction radiographs has potential benefit.

A Biomechanical Comparison of Fiberglass Casts and 3-Dimensional-Printed, Open-Latticed, Ventilated Casts.

Background: The aim of this study was to quantify the stabilizing properties of a 3-dimensional (3D)-printed short-arm cast and compare those properties with traditional fiberglass casts in a cadaveric subacute distal radius fracture model. Methods: A cadaveric subacute fracture model was created in 8 pairs of forearms. The specimens were equally allocated to a fiberglass cast or 3D-printed cast group. All specimens were subjected to 3 biomechanical testing modalities simulating daily life use: flexion and extension of digits, pronation and supination of the hand, and 3-point bending. Between each loading modality, radiological evaluation of the specimens was performed to evaluate possible interval displacement. Interfragmentary motion was quantified using a 3D motion-tracking system. Results: Radiographic assessment did not reveal statistically significant differences in radiographic parameters between the 2 groups before and after biomechanical testing. A statistically significant difference in interfragmentary motion was calculated with the 3-point bending test, with a mean difference of 0.44 (±0.48) mm of motion. Conclusions: A statistically significant difference in interfragmentary motion between the 2 casting groups was only identified in 3-point bending. However, the clinical relevance of this motion remains unclear as the absolute motion is less than 1 mm. The results of this study show noninferiority of the 3D-printed casts compared with the traditional fiberglass casts in immobilizing a subacute distal radius fracture model. These results support the execution of a prospective randomized clinical trial comparing both casting techniques.

The Emergent Evaluation and Treatment of Elbow and Forearm Injuries.

This article provides an updated review of the emergent evalution and treatment of elbow and forearm injuries in the emergency department. Clinically necessary imaging is discussed. Common and uncommon injuries of the elbow and forearm are reviewed with an emphasis on early recognition, efficient management, and avoidance of complications. The astute emergency physician will rely on a focused history and precise examination, applied anatomic knowledge, and strong radiographic interpretative skills to avoid missed injuries and complications.
