Risk factors for fracture redisplacement after reduction and cast immobilization of displaced distal radius fractures in children: a meta-analysis

Antegrade ESIN technique via the Kocher interval reduces radiation exposure and accelerates recovery in pediatric DRDMJ fractures: A comparative study with cadaveric validation

BACKGROUND

Distal radius diaphyseal-metaphyseal junction (DRDMJ) fractures in children often require surgical intervention due to the unique anatomical characteristics and high failure rate of nonoperative treatment. However, the choice of internal fixation remains a challenge for pediatric orthopedic surgeons. Traditional fixation methods, including plate and screw fixation, crossed Kirschner wires (K-wires), and external fixators, have drawbacks such as extensive local trauma and the risk of physeal injury. This study evaluates the clinical efficacy of antegrade elastic stable intramedullary nailing (ESIN) for DRDMJ fractures in children, comparing it with the crossed K-wire technique.

METHODS

A retrospective analysis was conducted on 47 pediatric patients with DRDMJ fractures treated between June 2018 and January 2023. Patients were divided into an antegrade ESIN group (n = 20) and a crossed K-wire group (n = 27). Demographic data, perioperative parameters (operative time, radiation exposure), and postoperative recovery indicators (duration of internal/external fixation, radiographic healing time, wrist function recovery) were collected. All patients were followed up for at least 12 months, and complications were recorded. The Garland-Werley score was used to assess wrist function. Additionally, a cadaveric study was performed to validate the neurovascular safety of antegrade ESIN insertion via the middle third of the radial head-radial tuberosity axis within the Kocher interval.

RESULTS

All patients achieved radiographic union, with no cases of dorsal interosseous nerve injury, tendon rupture, or refracture. There were no significant differences between the two groups in terms of radiographic healing time or wrist function scores at 12 months postoperatively (P > 0.05). However, compared to the crossed K-wire group, the antegrade ESIN group demonstrated a significantly shorter operative time by 10.71 min (P = 0.002), reduced fluoroscopy use by 2.74 exposures (P = 0.001), and a shorter postoperative cast immobilization duration by 9.11 days (P < 0.001). Additionally, the antegrade ESIN group exhibited a higher rate of excellent wrist function scores at the 3-month follow-up. The cadaveric study confirmed that needle insertion through the middle third of the Kocher interval safely avoided the dorsal interosseous nerve, with no risk of nerve injury in either pronation or supination positions.

CONCLUSION

Antegrade ESIN and crossed K-wire fixation provide comparable long-term functional and radiographic outcomes for pediatric DRDMJ fractures. The antegrade ESIN technique, performed through the middle third of the radial head-radial tuberosity axis within the Kocher interval, effectively avoids dorsal interosseous nerve injury while significantly reducing operative time, minimizing intraoperative radiation exposure, and promoting early functional recovery. This technique may serve as a valuable surgical option for treating DRDMJ fractures in children.

[Upper extremity immobilization techniques in children]

OBJECTIVE

Conservative treatment of stable fractures of the upper extremity in children.

INDICATIONS

Undisplaced and age-tolerable displaced fractures of the hand, forearm, and elbow.

CONTRAINDICATIONS

Open fractures.

TREATMENT OPTIONS

Forearm splint/forearm cast for stable injuries to the radius or ulna. Long arm splint/long arm cast for injuries to the radius and ulna and after reduction of the forearm, as well as for stable, undisplaced injuries to the elbow. Intrinsic plus splint for injuries to the four fingers (excluding the thumb) and metacarpus.

FURTHER TREATMENT

For stable injuries, immobilization for analgesia for 3-4 weeks. Clinical check after treatment. In the case of repositioned fractures or fractures displaced within the spontaneous correction limits, clinical-radiological control (if necessary, with cast wedging) after 1 week. Immobilization for 4 weeks (prepubertal children) or 5 weeks (pubertal children).

RESULTS

Conservative treatment of fractures of the upper extremity is still the gold standard today. In pediatric patients in particular, but also in adult patients, correct healing of the fracture with good analgesia can be achieved with manageable effort and a good cost-benefit ratio through correct cast immobilization. A measurable parameter for monitoring a good cast is the cast index.

Metaphyseal distal radius fractures in adolescents: is closed reduction and casting sufficient for most?

PURPOSE

There is limited evidence to support decision-making in adolescents with metaphyseal distal radius fractures. This study aims to review injury patterns, treatments, and clinical outcomes in this age group.

METHODS

Patients aged 11-16 years presenting with metaphyseal distal radius fractures were obtained from our institutional trauma database. Radiographs and records were reviewed to obtain injury details, management, complications, and long-term sequelae.

RESULTS

One hundred and five fractures were included. Mean age was 12.6 years and 79% occurred in males. 75.2% were angulated and 24.8% off-ended. The median initial angulation was 22.1° (2.3-46.7), and the majority were dorsally displaced (74.3%). Emergent management for 91 (86.7%) patients was surgical with either manipulation under anaesthesia (MUA) and cast in theatre (59.3%), Kirschner wire (K-wire) fixation (35.8%), or open reduction internal fixation (ORIF) (3.3%). Fourteen patients were initially managed non-operatively, and 71.4% of these re-displaced requiring surgery. There was no statistical difference in final angulation of fractures managed with MUA and cast or fixation (5.35 vs. 5.5°, respectively). Complications occurred in 14.3%, including two cases of osteomyelitis. Twenty cases had final angulation of greater than 9°, but none underwent corrective osteotomy.

CONCLUSION

In adolescents, metaphyseal distal radius fractures have a higher risk of early re-displacement when not reduced in theatre; however, both casting and fixation resulted in similar final angulation. Complications were common at 14.3%, but only occurred in those that underwent fixation. Few long-term issues were observed in those treated in cast, even with up to 20° of residual angulation.

Safety and reliability of ultrasound-assisted reduction in the conservative management of completely displaced paediatric distal radius fractures

PURPOSE

To assess the efficacy of ultrasound-assisted reduction in the conservative management of completely displaced pediatric distal radius fractures.

METHODS

The efficacy of ultrasound-assisted reduction versus conventional reduction was compared in a single-centre, retrospective, cross-sectional study involving 51 consecutive paediatric patients with completely displaced distal radius fractures, following manual reduction, from May 2021 to May 2023. The study group received ultrasound-assisted reduction (n = 24), while the control group underwent conventional blind manual reduction (n = 27). Comparative analysis included general clinical data, initial reduction success rates, frequency of exposure to radiation during reduction, post-reduction alignment rates, post-reduction angulation, re-displacement rates, conservative treatment failure rates, pain scores, and wrist joint scores at the last follow-up.

RESULTS

All enrolled cases underwent manual reduction and conservative management. In the study group, all 24 patients underwent successful initial reduction procedures, with only one exposure to radiation during the entire process. Notably, no patient experienced re-displacement while in plaster, and the conservative treatment proved effective. The reduction and positioning rates were impressive, with success rates of 86.63 ± 3.65% in the coronal plane and 94.79 ± 3.06% in the sagittal plane. Furthermore, the post-reduction angulation was only 3.58 ± 0.65 degrees in the coronal plane and 8.70 ± 1.45 degrees in the sagittal plane. By contrast, within the control group comprising 27 patients, only 15 achieved successful initial reductions. Unfortunately, 12 patients required multiple exposure to radiation throughout the procedure. Furthermore, nine patients underwent re-displacement while in plaster and seven did not achieve successful conservative treatment. The alignment rates of the control group were similar to those of the study group (84.67 ± 4.35% in the coronal plane and 82.56 ± 5.45% in the sagittal plane). Similarly, the post-reduction angulation remained consistent, measuring 3.93 ± 0.87 degrees in the coronal plane and 12.03 ± 1.32 degrees in the sagittal plane. There were no statistically significant differences in pain scores during the process of fracture reduction and in wrist joint function scores at the final follow-up (P > 0.05).

CONCLUSION

Ultrasound-assisted reduction in the conservative management of completely displaced paediatric distal radius fractures can enhance the initial reduction success rate, decrease the risk of subsequent redisplacement, minimize patient exposure to radiation, and yield favorable clinical outcomes. It is a safe and reliable approach.

Pediatric Type I Open Both Bone Forearm Fractures: Predicting Failure of Nonoperative Management

BACKGROUND

In recent years, nonoperative treatment of pediatric type I open both bone forearm fractures (OBBFFs) with bedside irrigation, antibiotics, closed reduction, and casting has yielded low infection rates. However, risk factors for failure of type I OBBFF closed reduction have not been well described. Our purpose was to describe management of patients with type I OBBFFs at our institution and determine what factors are associated with failure of closed reduction in this population.

METHODS

This was a review of patients between 5 and 15 years of age who received initial nonoperative management for type I OBBFFs at one institution between 2015 and 2021. Primary outcome was success or failure of nonoperative management (defined as progression to surgical management). Secondary outcomes included infections, compartment syndromes, and neuropraxias. Other variables of interest were demographic information, prereduction and postreduction translation and angulation of the radius and ulna, cast index, and antibiotic administration.

RESULTS

Sixty-one patients (67.7% male) with 62 type I OBBFFs were included in this study. Following initial nonoperative management, 55 injuries (88.7%) were successfully treated in casts, while the remaining 7 (11.3%) required surgical intervention following loss of acceptable reduction in cast. Median cast index (0.84, IQR 0.8 to 0.9 vs. 0.75, IQR 0.7-0.8, P =0.020) and postreduction radius translation on anteroposterior films (32.0%, IQR 17.0% to 40.0% vs. 5.0%, IQR 0.0% to 26.0%, P =0.020) were higher among those who failed nonoperative management. Multivariable logistic regression models identified increased odds of failure for every SD (0.7) increase in cast index (OR 3.78, P =0.023, 95% CI: 1.4-14.3) and 25% increase in postreduction radius translation on anteroposterior films (OR 7.39, P =0.044, 95% CI 1.2-70.4). No infections or compartment syndromes and 2 transient ulnar neuropraxias occurred.

CONCLUSIONS

Closed reduction of type I OBBFFs was successful in 88.7% of cases. There were no infections after nonoperative management. Increases in cast index of 0.7 and postreduction radius translation on anteroposterior radiographs of 25% were associated with increased likelihood of failure, thus requiring surgery; age was not.

Is reduction necessary in overriding metaphyseal distal radius fractures in children under 11 years: a systematic review and meta-analysis of comparative studies

OBJECTIVE

To determine the necessity of reduction in the treatment of overriding metaphyseal distal radius fractures (DRF) in children under 11 years.

METHODS

In this systematic review and meta-analysis, PubMed, Embase, and Cochrane databases were searched to retrieve studies published from inception to 2023. Two reviewers independently screened for studies with observational or randomized control design comparing two treatments for overriding metaphyseal DRF in patients under 11 years: simple casting without reduction (SC group) versus closed reduction plus casting or pin fixation (CRC/F group); with varying outcomes reported (CRD471761). The risk of bias was assessed using the ROBINS-I tool.

RESULTS

Out of 3,024 screened studies, three met the inclusion criteria, 180 children (mean age 7.1 ± 0.9 years) with overriding metaphyseal DRF: SC-group (n = 79) versus CRC/F-group (n = 101). Both treatment groups achieved 100% fracture consolidation without requiring further manipulation. The SC-group showed significantly fewer complications (mean difference [MD] 0.08; 95% CI [0.01, 0.53]; I2 = 22%; P < 0.009) and trends towards better sagittal alignment (MD 5.11; 95% CI [11.92, 1.71]; I2 = 94%; P < 0.14), less reinterventions (MD 0.31; 95% CI [0.01, 8.31]; P < 0.48), and fewer patients with motion limitation at the end of follow-up (MD 0.23; 95% CI [0.03,  1.98]; P < 0.18), although these findings were not statistically significant.

CONCLUSIONS

Despite a limited number of studies comparing SC versus CRC/F in overriding DRF in children under 11 years, this study suggests that anatomical reduction is not necessary. Treating these fractures with SC, even when presenting with an overriding position, leads to reduced complications, shows a trend towards fewer reinterventions, improved sagittal alignment, and less limitation in patient motion.

Closed reduction and cast immobilization of overriding distal forearm fractures under nitrous oxide as conscious sedation without the use of imaging control

PURPOSE

The management of overriding distal forearm fractures is still controversial. This study aimed to evaluate the efficacy of immediate closed reduction and cast immobilization (CRCI) at the emergency department (ED) using equimolar nitrous oxide (eN2O2) as conscious sedation, and without the use fluoroscopic assistance.

METHODS

Sixty patients with overriding distal forearm fracture were included in the study. All procedures were performed in the ED without fluoroscopic assistance. Antero-posterior and lateral wrist radiographs were taken after CRCI. Follow-up radiographs were taken 7 and 15 days post-reduction, and at cast removal to evaluate callus formation. Depending on the radiological outcome, two groups of patients could be identified: Group 1 (satisfactory reduction and maintenance of alignment) and Group 2 (poor reduction or secondary displacement requiring further manipulation and surgical fixation). Group 2 was additionally divided into Group 2A (poor reduction) and Group 2B (secondary displacement). Pain was assessed using Numeric Pain Intensity (NPI) score, while functional outcome was measured according to Quick DASH questionnaire.

RESULTS

Mean age at the time of injury was 9.2 ± 2.4 years (range, 5-14). Twenty-three (38%) patients were aged between 4 and 9 years old, 20 (33%) patients between 9 and 11, 11 (18%) patients between 11 and 13, and 6 (10%) patients between 13 and 14. The mean follow-up time was 45.6 ± 12 months (range, 24-63). Satisfactory reduction with maintenance of alignment was achieved in 30 (50%) patients (Group 1). Re-reduction was performed in the remaining 30 (50%) patients (Group 2) due to poor reduction (Group 2A) or secondary displacement (Group 2B). No complications related to the administration of eN2O were recorded. No statistically significant difference could be identified between the three groups for any clinical variable (Quick DASH and NPI).

CONCLUSION

Overriding distal forearm fractures may be safely treated with CRCI at ED using eN2O2 as conscious sedation. However, fluoroscopic assistance during CRCI might significantly improve the quality of reduction thus avoiding further treatment as the lack of relaxed muscle can restrain reduction.

Increase in gap index over time after reduction of unstable paediatric both-bone forearm fracture does not cause displacement

This study investigated the effects of changes in the gap index on fracture displacement during follow-up. Patients who underwent closed reduction and casting with a diagnosis of unstable paediatric both-bone forearm fractures and a cast index < 0.8 were retrospectively evaluated. Patients were divided into Groups 1 and 2 based on their gap index (<0.15 and >0.15, respectively). Anteroposterior and lateral displacements of the radius and ulna and the gap index of the cast were measured on the X-ray after the first reduction and on the last X-ray before plaster removal. The mean patient age (n = 94, 74 boys and 20 girls; 51 in Group 1 and 43 in Group 2) was 7.09 ± 2.66 years. Fracture union times (plaster removal) were 38.8 ± 7.1 days. The mean cast index was 0.76 ± 0.05 (0.59-0.8). Both groups had similar distributions in terms of age, sex, fracture side, anatomic location and plaster removal time (p > 0.05). No significant differences were observed in either group in any radial or ulnar angulation values at any time point or the difference between the first and last values (all p > 0.05). Moreover, the gap index difference between the first and last measurements was significantly different in both groups (p = 0.002). If the cast index remains <0.8, despite the increase in the gap index in both groups, the amount of fracture displacement was small and acceptable.

Predictors requiring special attention to prevent clavicle fracture nonunion: a systematic review of literature

Background

Clavicle fracture (CF) is the tenth most prevalent fracture, accounting for an annual incidence of 37/10,000. This systematic review highlights the factors contributing to the nonunion union of the clavicular fracture.

Method

A systematic search was conducted using three web-based databases up to August 12, 2022, for conducting qualitative analysis. Articles were screened for relevance, and only studies that met inclusion criteria based on PECOS; P (patients): participants diagnosed with clavicular fracture; E (exposure): nonunion, C (control): not applicable; O (outcomes): factors contributing to nonunion or delayed union; S (studies): trials and observational studies. The Newcastle-Ottawa Scale was used to assess the quality of the cohort studies. The Cochrane risk of bias tool was used to assess the bias in randomized control trials.

Results

Ten studies were selected after the final literature search. Two thousand seven hundred and sixty-six adult participants who were radiologically and clinically diagnosed with nonunion clavicular fracture were included to pool the qualitative results. Fall was the most dominant cause of clavicular fracture, followed by road traffic collisions. Open reduction was widely used to treat nonunion correction. The qualitative results suggested a prominent correlation of nonunion with advancing age, female gender, high energy trauma, high Disabilities of the Arm, Shoulder, and Hand Score, smoking, fracture displacement, clavicular shortening, the callus on radiography, and fracture movement. The mid-shaft fracture was the most dominant type of fracture in the included studies; highly associated with nonunion in comparison to medial or lateral CF. The previous history of operation was an independent factor contributing to nonunion.

Conclusion

The results of this systematic review suggested the predictors contributing to nonunion in the CF. Demographic factors such as advancing age with female gender are at higher risk of developing clavicular nonunion. Smoking was the most dominantly highlighted environmental factor contributing to nonunion. Diaphyseal or midshaft fracture was the most common site for nonunion. Therefore, we suggested that patients with the predictors mentioned above require special attention to prevent nonunion of the CFs. More studies should be conducted on this subject to assess the factors that pose a risk associated with the nonunion of the bone for better clinical management and outcomes of the fracture.

Intramedullary Kirschner wire fixation of displaced distal forearm fractures in children

AIM OF THE WORK

This study was designed to highlight internal fixation by intramedullary K-wires for displaced distal forearm fractures among children and analyze the results of this technique. We hypothesize that physis-sparing intramedullary fixation prevents displacement with a lower complication rate.

METHODS

This prospective case series involving 47 patients was conducted between February 2018 and December 2019. All patients with open physis presented with recent displaced distal forearm fractures were included, and all of them were treated with an intramedullary k-wire fixation for both bones with the assessment of the union rate, union time, suspected complication, radiographic evaluation, and functional outcome.

RESULTS

The study population consisted of 31 boys (66%) and 16 girls (34%). The mean age of the patients was 10.68 ± 2.728 years (range, 7-15 years). All fractures were united in a median of 6 weeks (range, 4-8 weeks), The functional outcome after 12 months was normal in 42 patients (89.4%), whereas, in five patients (10.6%), the functional parameters were minimally reduced. The median preoperative angulation improved from 36° (range, 24°-52°) preoperatively to 4° (range, 0°-10°) on immediate postoperative radiographs. After 12 months, the median angulation was 2° (range, 0°-7°) (p < 0.001). The angulation of the distal radius immediately after surgery and at the final follow-up was statistically correlated with the functional outcome (p < 0.001 and 0.002, respectively).

CONCLUSION

This technique provides a good result with less susceptibility to re-displacement and low complication rates.

Clinical observation on the treatment of displaced distal radial and ulnar fractures in children by closed manipulation combined with splinting

Objective

The aim of this study was to investigate the clinical efficacy of closed manipulation combined with splinting in the treatment of displaced distal radial and ulnar fractures in children.

Methods

A total of 82 children with displaced fractures of the distal radial and ulnar segment who met the inclusion criteria and were treated as outpatients or inpatients in the orthopedic department of Guangzhou Orthopedic Hospital, from January 2016 to June 2022 were randomly divided into an observation group and a control group: 41 children in the observation group were treated with closed manipulation combined with splint fixation; 41 children in the control group were fixed with incisional repositioning elastic nails combined with internal plates. The Anderson efficacy grading, visual analog scale (VAS) score, fracture healing time, treatment cost, hospital days, and complications were observed and compared between the two groups.

Result

The efficacy was evaluated according to the Anderson forearm fracture efficacy evaluation criteria, and the results of statistical analysis showed no statistically significant differences between the two groups (P > 0.05). At 3 and 7 weeks after treatment, the VAS scores of children in both groups decreased (P < 0.05), and the VAS scores in the observation group were significantly lower than those in the control group (P < 0.05), indicating that the observation group had a significant advantage in the relief of pain after treatment. The fractures healed in both groups after treatment with the two different methods, and the difference in healing time between the two groups was not statistically significant (P > 0.05). The length of hospital stay, treatment cost, and complication ratio were significantly lower in the observation group than in the control group (P < 0.05).

Conclusion

In children with displaced fractures of the distal radial and ulnar segments, treatment by manual repositioning with external splinting can achieve satisfactory results with simple operation, low cost, short hospital stay, and few complications, which is especially suitable to be promoted in primary hospitals and has good social benefits.

Distal radius fractures in children aged 5-12 years: a Swedish nationwide register-based study of 25 777 patients

BACKGROUND

Distal radius fracture (DRF) is the most common type of fracture in children. There is no clear consensus on primary treatment for complete DRFs. Kirschner wire (K-wire) fixation has been recommended, to avoid the risk of redislocation. However, recent studies have indicated that casting can be sufficient, at least for children with two or more years left to grow. There is no recent study regarding pediatric DRFs and the extent of K-wire fixations in the Swedish population. The purpose of this study was to investigate epidemiology and treatment of pediatric DRFs registered in the Swedish Fracture Register (SFR).

METHODS

In this retrospective study, based on data from SFR for children aged 5-12 years with DRF between January 2015 and October 2022, we investigated epidemiology and choice of treatment. Sex, age, type of DRF, treatment, cause and mechanism of injury, were analyzed.

RESULTS

In total, 25,777 patients were included, 7,173 (27%) with complete fractures. Number and peak age of girls vs. boys with fractures were 11,742 (46%), 10 years, and 14,035 (54%), 12 years, respectively. Odds ratio (OR) for a K-wire fixation in girls vs. boys was 0.81 (95% confidence interval (CI) 0.74-0.89, p < .001). With age 5 -7 years as reference, OR for age group 8-10 years was 0.88 (95% CI 0.80-0.98 p = .019) and OR for age group 11-12 years was 0.81 (95% CI 0.73-0.91 p =  < .001.

CONCLUSION

Casting only was the preferred treatment for all fractures (76%). Boys acquired DRFs more often than girls, with a peak age of 12 years. Younger children and boys with a complete fracture were more likely than older children and girls to receive a K-wire. Further research regarding indications for K-wiring of DRFs in the pediatric population is needed.

Clinical Follow-Up without Radiographs Is Sufficient after Most Nonoperatively Treated Distal Radius Fractures in Children

Distal forearm fractures are common in children and are usually treated nonoperatively. No consensus has been reached on how to perform clinical and radiographic follow-up of these fractures. Our aim was to study whether radiographic and clinical follow-up is justified. We included 100 consecutive patients with non-operatively treated distal forearm fractures who were treated at Oulu University Hospital in 2010-2011. The natural history of the fractures during the nonoperative treatment was analyzed by measuring the potential worsening of the alignment during the follow-up period. The limits of acceptable fracture position were set according to the current literature using "strict" or "wide" criteria for alignment. We determined the rate of worsening fracture position (i.e., patients who reached the threshold of unacceptable alignment). In relation to splinting, we evaluated how many patients benefited from clinical follow-up. Most of the fractures (98%) preserved acceptable alignment during the entire follow-up period when wide criteria were used. The application of stricter criteria for alignment in radiographs showed loss of reduction in 19% of the fractures. Worsening of the alignment was recognized at a mean of 13 days (range 5-29) after the injury. One in three (32%) patients needed some intervention due to splint loosening or failure. Radiographic follow-up of nonoperatively treated distal forearm fractures remains questionable. Instead, clinical follow-up is important, as 32% of patients needed their splints fixed.

Pediatric Radial Neck Fractures: A Systematic Review Regarding the Influence of Fracture Treatment on Elbow Function

Background: This review aims to identify what angulation may be accepted for the conservative treatment of pediatric radial neck fractures and how the range of motion (ROM) at follow-up is influenced by the type of fracture treatment. Patients and Methods: A PRISMA-guided systematic search was performed for studies that reported on fracture angulation, treatment details, and ROM on a minimum of five children with radial neck fractures that were followed for at least one year. Data on fracture classification, treatment, and ROM were analyzed. Results: In total, 52 studies (2420 children) were included. Sufficient patient data could be extracted from 26 publications (551 children), of which 352 children had at least one year of follow-up. ROM following the closed reduction (CR) of fractures with <30 degrees angulation was impaired in only one case. In fractures angulated over 60 degrees, K-wire fixation (Kw) resulted in a significantly better ROM than intramedullary fixation (CIMP; Kw 9.7% impaired vs. CIMP 32.6% impaired, p = 0.01). In more than 50% of cases that required open reduction (OR), a loss of motion occurred. Conclusions: CR is effective in fractures angulated up to 30 degrees. There may be an advantage of Kw compared to CIMP fixation in fractures angulated over 60 degrees. OR should only be attempted if CR and CRIF have failed.

Outcomes and Cost of Reduction of Overriding Pediatric Distal Radius Fractures

BACKGROUND

This study compared radiographic outcomes of pediatric patients undergoing closed reduction of 100% displaced distal radius fractures to a historical, published cohort treated with casting alone. We also examined the expense associated with sedated reduction.

METHODS

Single-center, retrospective cohort study examining radiographic outcomes following reduction of 100% translated distal radius fractures in 50 consecutive pediatric patients. Radiographic outcomes were compared with a historical cohort published by Crawford and colleagues. Charges associated with emergency department (ED) and clinic visits were compared between the reduction cohort and a comparison cohort of 13 patients with fractures not requiring reduction.

RESULTS

Forty-nine children (mean age 4.7 y) were included in this study. Duration of casting averaged 51 days and ED visit duration was 6.6±2.5 hours. Mean sagittal and coronal angulation at time of injury were 16.4 and 15.6 degrees, respectively, and were 13.2 and 9.4 degrees at the time of final follow-up. All fractures achieved radiographic union. Eighteen patients underwent a total of 21 unexpected cast changes. No patients required repeat sedation or surgical management.Angulation after casting was significantly better in the reduction cohort compared with the casting-only cohort initially, however, at final follow-up, both coronal and sagittal angulation were significantly worse in the reduction cohort compared with the casting-only cohort (coronal angulation 8.59 vs. 0.75, P<0.0001; sagittal angulation 13.49 vs. 2.2, P<0.0001).Charge analysis compared 46 patients in the reduction cohort to 13 patients with unreduced fractures from the same institution during the same time period. Mean clinic charges were similar ($1957 vs. $2240, P=0.3008). ED charges were higher in the reduction cohort compared with the nonreduction cohort ($7331 vs. $3501, P<0.001), resulting in higher total charges in the reduction cohort ($9245.04 vs. $5740.99, P<0.001).

CONCLUSIONS

While closed reduction of 100% translated distal radius fractures in the pediatric population improves angulation initially, casting alone may provide similar or better radiographic outcomes, expedited care, reduced patient exposure to the risks of procedural sedation, and avoidance of ED charges associated with procedural sedation.

Bioresorbable implants vs. Kirschner-wires in the treatment of severely displaced distal paediatric radius and forearm fractures - a retrospective multicentre study

BACKGROUND

Distal radius fractures are very common in paediatric patients. Severely displaced fractures may require surgical intervention. The gold standard surgical method is percutaneous K-wire osteosynthesis followed by immobilisation. Metal implants can be removed with a second intervention; however, these extra procedures can cause further complications. Several studies confirm the benefits of bioabsorbable implants for paediatric patients. The aim of this retrospective study was to compare the complication rates of displaced distal metaphyseal radius (AO 23r-M/3.1) and forearm (AO 23-M/3.1) fractures in children operated on with K-wires versus a novel technique with bioresorbable implants.

METHODS

We retrospectively reviewed 94 patients in three paediatric trauma centres who underwent operations due to severely displaced distal forearm or metaphyseal radial fractures between January 2019 and January 2020. The mean age was 8.23 (ranging from 5-12). 30 patients (bioresorbable group, BR-group) were treated with biodegradable PLGA implants (Bioretec®, ActivaPin®), 40 patients with one or two stainless steel Kirschner-wires (K-wires, Sanatmetal®) which were buried under the skin (KW I-group) and 24 children with K-wires left outside the skin. (KWII. Group). We examined the number of minor and major complications as well as the need for repeated interventions. Follow-up was at least one and half year.

RESULTS

There was no significant difference between the complication rates at the two KW groups (p = 0.241; Cramer's V = 0.211), while the complication rate of the BR group was significantly lower. (p = 0.049; Cramer's V = 0.293 and p = 0.002; Cramer's V = 0.418 respectively). No later than half a year after the injury, no difference was observed between the functional outcomes of the patients in each group. One and a half years after the injury, no signs of growth disturbance were found in any of the children. No second surgical intervention was required in the BR group.

CONCLUSIONS

Surgeries with bioresorbable intramedullary implants may have fewer complications than K- wire osteosynthesis in the treatment of severely displaced distal forearm fractures. The benefits are most pronounced in the first six weeks after surgery, reducing the number of outpatient visits and increasing the child's sense of comfort. As no second intervention is required, this can lead to significant cost savings. After half a year, there is no difference in the outcomes between the different surgical treatment strategies.

Pediatric fracture reduction in the emergency department

Limb fractures are a large part of pediatric trauma activity. Conservative treatment is possible because of children's bone remodeling potential. In case of displaced fractures, when a closed reduction can be done in the emergency room (ER), this avoids general anesthesia, hospitalization and the associated costs. In well-defined situations, there is a consensus about the indication for fracture reduction in the ER. Some complex fracture cases require immediate treatment in the operating room: intra-articular fractures, pathological fractures, fractures with associated skin, nerve or vascular injuries and/or early signs of compartment syndrome. And last, there is another set of fractures where the indication is not so clear. To specify the indications and technical implementation of these treatments in ER, we did a non-systematic narrative review of literature in the MEDLINE® database using the PubMed search engine to query "emergency room AND children AND fracture AND reduction". We retained the most recent articles addressing the questions related to indications and their care, sedation protocol and complications. The sedation protocol for the ER is established collaboratively by surgical, ER and anesthesia teams. The residual angulation that can be tolerated after reduction depends on the patient's age, remaining growth potential and location of the fracture line. When reduction is done in the ER, the complication and secondary displacement rates are not higher, although surgeon experience and specific procedural training appear to be crucial.

Assessing Compliance to National Guidelines for Pediatric Wrist and Ankle Fractures in a District General Hospital

Pediatric ankle and wrist fractures are very common injuries encountered by orthopedic departments. The National Institute of Clinical Excellence has published guidelines that should be adhered to when treating these common fractures. This audit included 560 patients that have sustained wrist and ankle fractures between 2008 and 2019 at Queen Elizabeth Hospital Burton (QHB) that required surgical management. The results show that 99.7% (478/479) wrist fractures and 70.8% (57/81) of ankle fractures received surgical management within the timeframe outlined by NICE. This audit has shown that QHB has been successfully treating wrist fractures within the guidelines set by NICE but has failed to meet the standards for ankle fractures.

Analysis of Postoperative Complications and Related Factors Affecting Prognosis in 50 Patients with Distal Radius Fractures

Objective

To explore the postoperative complications of distal radius fractures and analyze the related factors that affect its prognosis.

Methods

The clinical data of 50 patients with distal radius fractures admitted to our hospital from October 2016 to September 2019 were retrospectively analyzed. All patients were followed up for 6–12 months, and their postoperative complications were recorded. Collect general patient information and related clinical data. During the follow-up process, Gartland and Werley wrist function scoring system was used to evaluate the prognosis of patients' joint function. Univariate analysis and multiple logistic regression models were used to analyze the related factors that affected the prognosis of patients.

Results

15 patients with postoperative complications were found during the follow-up period, with an incidence rate of 30.00%. Univariate analysis showed that the patient's age, cause of injury, AO classification, shortened deformity, whether it was osteoporosis, surgical method, whether it was combined with other fractures on the same side, whether it was comminuted fracture, and the time to start postoperative exercise were all related to the distal radius. The prognosis of fractures is related (P < 0.05). Multivariate logistic analysis showed that age, AO classification, surgical method, whether it was combined with other fractures on the same side, whether it was comminuted fracture, and the time to start postoperative exercise were the independent factors affecting the prognosis of distal radius fractures (P < 0.05).

Conclusion

The postoperative complications of distal radius fractures are higher. The prognosis is related to the patient's age, AO classification, surgical method, whether it is combined with other fractures on the same side, whether it is comminuted fracture, and the time to start postoperative exercise. Therefore, choosing an appropriate surgical method and starting exercise in time can effectively improve the recovery of the patient's wrist function and reduce the occurrence of complications.

[Typical liability damages of the upper extremities in childhood and their evaluation]

Legal appraisals of possible treatment errors in childhood and adolescence are rare, often refer to the treatment of trauma of the upper limbs and are frequently recognized. From the activity of the first author as an expert witness 31 expert opinions (25%) referred to the upper limbs. Supracondylar humeral fractures, radius neck fractures, radial condyle fractures and distal radius fractures were predominant. A primary treatment error was determined in 14 patients and a secondary error in 7 patients. This corresponds to a recognition rate of 68%. The aim of this study was the reflection and the development of a prevention strategy. Insufficient recognition of instability (radial condyle), inadequate reduction and inadequate stabilization (radius neck, supracondylar) as well as untreated malalignments and secondary dislocations (wrist) were the main reproaches. Poor communication and deficient documentation often aggravate the situation. Working along clear algorithms can help to avoid legal proceedings and assignment of guilt.

Ultrasound in forearm fractures: a pragmatic study assessing the utility of Point of Care Ultrasound (PoCUS) in identifying and managing distal radius fractures

BACKGROUND

Point of Care Ultrasound (PoCUS) is a safe, non-invasive tool for identifying distal radius fractures and can potentially be utilised to assist clinicians to reduce displaced fractures. We aim to test whether PoCUS is accurate to identify distal radius fractures and to determine how PoCUS performs as a tool to confirm a successful fracture reduction.

METHODS

A pragmatic prospective observational study was done in adult patients presenting with forearm injuries resulting in Colle's type distal radius fractures. Adults who presented to the emergency department (ED) with a suspected distal forearm fracture from August 2018 to July 2019 were conveniently sampled for inclusion into the study when a trained ED ultra-sonographer was available. PoCUS scans over the point of maximal tenderness were done using a high frequency linear transducer (7.5-10 mHz) prior to X-ray. Patients who required a manipulation of the fracture had a second ultrasound scan immediately after the procedure before the second X-ray was ordered. PoCUS scans were compared to X-rays for accuracy in both groups.

RESULTS

Fractures were identified in 44 out of 47 included patients using both PoCUS and X-ray modalities. This showed a sensitivity of 100% (95% CI: 90-100%) and specificity of 100% (95% CI: 31-100%). Fracture manipulation was required in 35 out of 44 patients. The sensitivity and specificity of PoCUS in determining alignment accuracy when compared to X-ray were 100% (95% CI: 83-100%) and 64% (95% CI: 32-88%) respectively. The PPV and NPV were 86% (95% CI: 66-95%) and 100% (95% CI: 56-100%) respectively. Ten out of 44 (23%) patients with distal radius fractures ultimately required an Open Reduction and Internal Fixation (ORIF).

CONCLUSION

Our study supports the use of PoCUS for identifying distal radius forearm fractures and may have some value in assisting clinicians to determine post reduction success. We still advocate using standard X-ray radiographs to confirm successful or adequate cortical alignment following a manipulation.

Management of Distal Radius Fractures in Adolescent Patients

BACKGROUND

While management recommendations for distal radius fractures in both young and skeletally mature patients have been generally well-established, controversy still exists regarding optimal management in adolescent patients approaching skeletal maturity. Thus, the goal of this review is to analyze relevant literature and provide expert recommendations regarding the management of distal radius fractures in this patient population.

METHODS

A PubMed search was performed to identify literature pertaining to distal radius fractures in adolescent patients, defined as 11 to 14 years in girls and 13 to 15 years in boys. Relevant articles were selected and summarized.

RESULTS

Distal radius fractures demonstrate significant potential for remodeling of angular deformity and bayonet apposition, even in patients older than 12 years of age. Rotational forearm range of motion and functional outcomes are acceptable with up to 15 degrees of residual angulation. Closed reduction and percutaneous pinning reduces fracture redisplacement but has a high associated complication rate. There is no literature comparing plate versus pin fixation of distal radius fractures in the pediatric population, but in adults plate fixation is associated with higher cost with no improvement in long-term functional outcomes.

CONCLUSIONS

Remodeling can still be expected to occur in adolescent patients, and even with residual deformity functional outcomes after distal radius fractures are excellent. Up to 15 degrees of residual angulation can be accepted before considering operative management. Smooth pins should be considered over plates as first-line operative management for unstable fractures that fail nonoperative treatment.

Kirschner Wire Fixation of Distal Radius Fractures, Indication, Technique and Outcomes

Distal radius fractures are the most common upper extremity fracture that present to US emergency departments. Given the variable presentation, including age and fracture pattern, there are many techniques that have been utilized to treat them. Closed reduction and percutaneous pin (CRPP) fixation remains a viable option in extra-articular and simple intra-articular fracture patterns. CRPP techniques flourished in the mid-twentieth century until the treatment patterns shifted to primarily volar-locked plating in the twenty-first century. Although several meta-analyses have been performed comparing outcomes and complications of CRPP versus alternative methods, controversy remains over which treatments are superior.

Cast immobilization in bayonet position versus reduction and pin fixation of overriding distal metaphyseal radius fractures in children under ten years of age: a case control study

PURPOSE

Completely displaced distal radius fractures in children have been traditionally reduced and immobilized with a cast or pin fixed. Cast immobilization leaving the fracture displaced in the bayonet position has been recently suggested as a non-invasive and effective treatment alternative. This is a pilot comparative study between reduction and no reduction.

METHODS

We assessed subjective, functional and radiographic outcome after a minimum 2.5-year follow-up in 12 children under ten years of age who had sustained a completely displaced metaphyseal radius fracture, which had been immobilized leaving the fracture in an overriding position (shortening 3 mm to 9 mm). A total of 12 age-matched patients, whose similar fractures were reduced and pin fixed, were chosen for controls.

RESULTS

At follow-up none of the 24 patients had visible forearm deformity and the maximal angulation in radiographs was 5° Forearm and wrist movement was restored (< 10° of discrepancy) in all 24 patients. Grip strength ratio was normal in all but three surgically treated patients. All patients had returned to their previous activities. One operatively treated boy who was re-operated on reported of pain (visual analogue scale 2).

CONCLUSION

The results of this study do not demonstrate the superiority of reduction and pin fixation over cast immobilization in the bayonet position of closed overriding distal metaphyseal radius fractures in children under ten years with normal neurovascular findings.
