RESUMO

BACKGROUND: Femoral neck fractures (FNFs) in young adults are usually caused by high-energy trauma, and their treatment remains a challenging issue for orthopedic surgeons. The quality of reduction is considered an important factor in improving the poor prognosis of patients with FNFs. In recent years, positive buttress closed reduction technique has received widespread attention in the treatment of FNFs. This comprehensive literature review is designed to encapsulate the impacts of both non-anatomic and anatomic reduction on the biomechanical stability, clinical outcomes, and postoperative complications in the management of FNFs, conjecture the efficacy of positively braced reduction techniques and provide a thorough summarization of the clinical outcomes. METHODS: In this literature review, we have examined all clinical and biomechanical studies related to the treatment of FNFs using non-anatomical reduction or positive and negative buttress reduction. PubMed, Web of Science, Google Scholar and Embase Library databases were searched systematically for studies published before September 1, 2023. Published literature on fracture reduction techniques for treating FNFs was reviewed. In addition, we evaluated the included literature using the MINORs tool. RESULTS: Although the "arch bridge" structure formed by the positive buttress reduction technique improved the support to the cortical bone and provided a more stable biomechanical structure, no significant differences were noted in the clinical efficacy and incidence of postoperative complications between the positive buttress reduction and anatomical reduction. CONCLUSION: Positive buttress reduction is an effective treatment method for young patients with FNFs. When facing difficult-to-reduce FNF, positive buttress reduction should be considered first, followed by anatomical reduction. However, negative buttress reduction should be avoided.

RESUMO

Introducción y objetivo: La fractura nasal es la lesión facial más común y más del 50 % de todas las fracturas faciales en adultos. Debido a que en muchas ocasiones no es diagnosticada y tratada oportunamente, puede generar diferentes grados de limitación funcional y resultados estéticos indeseables. Pocos estudios evalúan la satisfacción de los pacientes tratados con técnica cerrada de reducción de fractura nasal. Nuestro objetivo es valorar la satisfacción funcional y estética posterior a reducción cerrada de fractura de huesos nasales en un hospital de Colombia, mediante la escala de evaluación de síntomas de obstrucción nasal (NOSE, por sus siglas en inglés - nasal obstruction symptom evaluation) y la escala estética subjetiva. Material y método: Estudio observacional analítico prospectivo de pacientes con fractura nasal llevados a reducción cerrada en el Hospital Universitario de Santander, Colombia. Se registraron las puntuaciones de las escalas NOSE y estética subjetiva, antes y 2 meses después de la cirugía. Resultados: Evaluamos 55 pacientes, 90.9% hombres. La mediana de edad fue de 31 años (RIC 24-48). El contexto de lesión principal fue violencia física (40%), seguido de accidente de tránsito (32.7%). Tras el procedimiento, los pacientes presentaron mejoría de obstrucción nasal medida con la escala NOSE (p<0.001); antes de la cirugía el 89% presentaba obstrucción nasal moderada-severa, posteriormente descendió a 14.5%. La escala NOSE mostró fabilidad por consistencia interna con alfa de Cronbach de 0.8317. Tras la cirugía hubo aumento de la satisfacción respecto al aspecto nasal (p<0.001). Conclusiones: En nuestro estudio, el cuestionario NOSE permitió cuantificar la mejora de síntomas de obstrucción nasal en pacientes con reducción cerrada por fractura de huesos nasales. Observamos mejoría de síntomas obstructivos nasales y aumento de satisfacción estética.Nivel de evidencia científica 4c Terapéutico.(AU)


Background and objective: Nasal fracture is the most common facial injury, accounting for more than 50% of all facial fractures in adults. Because it is often not diagnosed and treated promptly, it can generate different degrees of functional limitation and undesirable aesthetic results. Few studies evaluate the satisfaction of patients treated with the closed nasal fracture reduction technique. Our objective is to evaluate functional and aesthetic satisfaction after closed reduction of a nasal bone fracture in a hospital in Colombia, using the nasal obstruction symptom evaluation (NOSE) and subjective aesthetic scales. Methods: Prospective analytical observational study of patients with nasal fractures undergoing closed reduction at the University Hospital of Santander, Colombia. The scores of the NOSE scales and subjective aesthetics were recorded, before and 2 months after surgery. Results: We evaluated 55 patients, 90.9% men. Median age 31 years (IQR 24-48). The main injury context was physical violence (40%), followed by traffic accident (32.7%). After the procedure, the patients presented improvement in nasal obstruction measured with the NOSE scale (p<0.001); before surgery, 89% had moderate-severe nasal obstruction, later it decreased to 14.5%. The NOSE scale showed reliability due to internal consistency with Cronbach's alpha of 0.8317. After surgery, there was an increase in satisfaction regarding the nasal appearance (p<0.001). Conclusions: The NOSE questionnaire allows us to quantify the improvement of nasal obstruction symptoms in patients with closed reduction due to nasal bone fracture. Improvement of nasal obstructive symptoms and increased aesthetic satisfaction was observed.Level of evidence 4c Terapeutic.(AU)

RESUMO

Aims: There is no level I evidence dealing with the optimal period of immobilization for patients with a displaced distal radial fracture following closed reduction. A shorter period might lead to a better functional outcome due to less stiffness and pain. The aim of this study was to investigate whether this period could be safely reduced from six to four weeks. Methods: This multicentre randomized controlled trial (RCT) included adult patients with a displaced distal radial fracture, who were randomized to be treated with immobilization in a cast for four or six weeks following closed reduction. The primary outcome measure was the Patient-Rated Wrist Evaluation (PRWE) score after follow-up at one year. Secondary outcomes were the abbreviated version of the Disability of Arm, Shoulder and Hand (QuickDASH) score after one year, the functional outcome at six weeks, 12 weeks, and six months, range of motion (ROM), the level of pain after removal of the cast, and complications. Results: A total of 100 patients (15 male, 85 female) were randomized, with 49 being treated with four weeks of immobilization in a cast. A total of 93 completed follow-up. The mean PRWE score after one year was 6.9 (SD 8.3) in the four-week group compared with 11.6 (SD 14.3) in the six-week group. However, this difference of -4.7 (95% confidence interval -9.29 to 0.14) was not clinically relevant as the minimal clinically important difference of 11.5 was not reached. There was no significant difference in the ROM, radiological outcome, level of pain, or complications. Conclusion: In adult patients with a displaced and adequately reduced distal radial fracture, immobilization in a cast for four weeks is safe, and the results are similar to those after a period of immobilization of six weeks.

RESUMO

Abstract Objective The present study compares the analgesic efficacy of two techniques to perform non-surgical reduction: fracture hematoma block and radial nerve supracondylar block. Methods Forty patients with fractures of the distal third of the radius, who required reduction, were selected in a quasi-randomized clinical trial to receive one of the anesthetic techniques. All patients signed the informed consent form, except for those who did not wish to participate in the study, had neurological injury, had contraindication to the procedure in the emergency room, or with contraindication to the use of lidocaine. To measure analgesia, the numerical pain rate scale was used at four different moments: preblock, postblock, during reduction, and after reduction; then three differences were calculated: the first between before and after blocking; the second between during reduction and after blockade; and the third between before blocking and after reduction. Results The fracture hematoma and supracondylar block groups showed the following mean values, respectively: 3.90 (1-10) and 3.50 (-6-10) in difference 1; 4.35 (-5-10) and 5.00 (-3-10) in difference 2; and 4.65 (1-10) and 3.80 (-3-10) in difference 3. Conclusion Both techniques proved to be efficient for analgesia, with mild superiority of hematoma block, but without statistical significance.


Resumo Objetivo O estudo compara a eficácia analgésica de duas técnicas para realizar redução incruenta: o bloqueio de hematoma da fratura e o bloqueio supracondilar de nervo radial. Métodos Quarenta pacientes com fraturas do terço distal do rádio, que necessitassem redução, foram selecionados em um ensaio clínico quasi-randomizado, para receber uma das técnicas anestésicas. Todos os pacientes assinaram o termo de consentimento ou assentimento, com exceção daqueles que não desejassem participar do estudo, tivessem lesão neurológica, com contraindicação ao procedimento na sala de emergências, ou com contraindicação ao uso da lidocaína. Para aferir a analgesia foi utilizada a escala numérica da dor em quatro momentos distintos: pré-bloqueio, pós-bloqueio, durante a redução e após a redução; em seguida, foram calculadas três diferenças: a primeira entre antes e após o bloqueio; a segunda entre durante a redução e após o bloqueio; e a terceira entre antes do bloqueio e após a redução. Resultados Os grupos do bloqueio de hematoma de fratura e bloqueio supracondilar apresentaram respectivamente os seguintes valores médios: 3.90 (1-10) e 3.50 (-6-10) na diferença 1; 4.35 (-5-10) e 5.00 (-3-10) na diferença 2; e 4.65 (1-10) e 3.80 (-3-10) na diferença 3. Conclusão As duas técnicas se provaram eficientes para analgesia, com discreta superioridade do bloqueio de hematoma, mas sem significância estatística.

Se incluyeron 30 pacientes. La edad promedio fue 6,3±2,2(3-10) años. La causa más frecuente del traumatismo fue la precipitación de altura en 63,3% de los casos. La posición del codo al momento del accidente fue en extensión en 90%. Todas las fracturas fueron cerradas. El tiempo promedio desde el accidente hasta su atención en emergencia fue de 8,5±13,4(2-72) horas. Los signos clínicos más frecuentes fueron dolor en 100,0%, limitación funcional en 96,7%, aumento de volumen 73,3% y deformidad 50,0%. Según la clasificación AO la más frecuente fue del tipo 13-M/3. 1 III en el 50% de los casos y según Gartland, las tipo IIIA en 53,3%. A las 4 semanas, 100,0% de las fracturas consolidaron, 13,3% presentó valgo y 6,7% varo en la radiografía anteroposterior. Mientras que, en la lateral, 33,3% antecurvatum. La media del ángulo de Baumann fue de 20,27±1,39 grados. La tasa de complicaciones fue de 16,66%, 2(6,7%) casos presentaron neuropraxia y 3(10,0%) granuloma. En conclusión, la Técnica Cruzada es segura en términos de reducción, funcionalidad y tasas de complicaciones en el seguimiento a medio plazo(AU)


Supracondylar fractures in children are associated with some complications. Its standard treatment is closed reduction and fixation with wires in different configurations. An observational, analytical, prospective and longitudinal study was made, with pediatric patients admitted with supracondylar humeral fractures surgically treated with Kirschner wires with the "Cross Technique" at the Hospital Central San Cristóbal from January to June 2022. 30 patients were included. The mean age was 6,3±2,2(3-10) years. The most frequent cause of trauma was high altitude precipitation in 63,3% of the cases. The position of the elbow at the time of the accident was 90% extended. All fractures were closed. The mean time from the accident to emergency care was 8,5±13,4(2-72) hours. The most frequent clinical signs were pain in 100,0%, functional limitation in 96.7%, volume increase in 73,3%, and deformity in 50,0%. According to the AO classification, the most frequent was type 13-M/3. 1 III in 50% of cases and according to Gartland, type IIIA in 53,3%.

RESUMO

BACKGROUND: Ultrasound has been used previously in fracture identification, analgesia delivery, and fracture reduction for patients in the emergency department. It has not been previously described as a tool for the guidance of closed fracture reduction in fifth metacarpal neck fractures ("boxer's fractures"). CASE REPORT: A 28-year-old man presented with hand pain and swelling after punching a wall. Point-of-care ultrasound revealed a significantly angulated fifth metacarpal fracture, which was confirmed with a subsequent hand x-ray study. After an ultrasound-guided ulnar nerve block, closed reduction was performed. Ultrasound was used to assess reduction and ensure improvement in bony angulation during the closed reduction attempts. Post-reduction x-ray study confirmed improved angulation and adequate alignment. Why Should an Emergency Physician Be Aware of This? Point-of-care ultrasound has previously had efficacy in fracture diagnosis and anesthesia delivery for fifth metacarpal fractures. Ultrasound can also be used at the bedside to assist in the determination of adequate fracture reduction when performing closed reduction of a boxer's fracture.

RESUMO

OBJECTIVES: To assess factors affecting the loss of reduction (LOR) in a large cohort of children with Salter-Harris Type II (SH II) distal radius physeal fractures treated with closed reduction. DESIGN: Retrospective chart review. SETTING: Pediatric Level I Trauma Center. PATIENTS/PARTICIPANTS: A total of 141 pediatric patients (73% male, average age: 12.15 ± 2.55 years) that had undergone closed reduction and casting for distal radius physeal fractures from 2006 to 2019 were included in this study. INTERVENTION: Closed reduction and casting. MAIN OUTCOME MEASUREMENTS: Five different radiographic measurements were analyzed at 4 different time points. Follow-up radiographs were assessed in relation to initial reduction. LOR was defined as >5 degrees change of angulation on PA radiographs, >10 degrees change of angulation on lateral radiographs, and/or >25% translation on PA or lateral radiographs. RESULTS: LOR was seen in 28.4% of the patients, most often (68%) in the first 2 weeks after initial reduction. Seven (17.5%) of these patients (average age: 15.2 ± 2.0 years) were treated surgically with closed reduction and percutaneous pinning (CRPP). Patients undergoing CRPP for LOR were an average of 3.4 years older ( P < 0.001) than those who underwent nonoperative treatment of LOR. Patients with initial angulation more than 5 degrees on the PA view to be twice as likely to have LOR ( P = 0.03). CONCLUSIONS: LOR was seen in nearly 1/3 of these patients. Patients with initial higher degree of angulation on the coronal plane are at higher risk for LOR. Age, not the degree of angulation, is the main predictor for potential surgical treatment. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

Closed reduction (CR) as an initial treatment for developmental hip dysplasia of the hip (DDH) in children aged 24 to 36 months is debatable; however, it could have better results than open reduction (OR) or osteotomies, because it is minimally invasive. The purpose of this study was to evaluate the radiological results in children (24-36 months) with DDH initially treated with CR. Initial, subsequent, final anteroposterior pelvic radiological records were retrospectively analyzed. The International Hip Dysplasia Institute was used to classify the initial dislocations. To evaluate the final radiological results after CR (initial treatment) or additional treatment (CR failed), the Ömeroglu system was used (6 points excellent, 5 good, 4 fair-plus, 3 fair-minus, and ≤2 poor). The degree of acetabular dysplasia was estimated using the initial acetabular index and the final acetabular index, Buchholz-Ogden classification was used to measure avascular necrosis (AVN). A total of 98 radiological records were eligible, including 53 patients (65 hips). Fifteen hips (23.1%) were redislocated, OR with femoral osteotomy and pelvic osteotomy was the preferred surgical treatment 9 (13.8%). The initial acetabular index versus final acetabular index in total population was (38.9º ± 6.8º) and (31.9º ± 6.8º), respectively (t = 6.5, P < .001). The prevalence of AVN was 40%. Overall AVN in OR, femoral osteotomy and pelvic osteotomy were 73.3% versus CR 30%, P = .003. Unsatisfactory results ≤ 4 points on the Ömeroglu system were observed in hips that required OR with femoral and pelvic osteotomy. Hips with DDH treated with CR initially might had better radiological results than those treated with OR and femoral and pelvic osteotomies. Regular, good, and excellent results, ≥4 points on the Ömeroglu system, could be estimated in 57% of the cases, in whom CR was successful. AVN is frequently observed in hips with failed CR.

RESUMO

PURPOSES: This study aimed to evaluate the clinical effect of the unlocking closed reduction technique (UCRT) for the displaced posterior pelvic ring fractures and to analyze the factors associated with failure of closed reduction and fixation. PATIENTS AND METHODS: Data from patients admitted with displaced posterior pelvic ring fractures initially treated with the URCT from July 2017 to January 2020 were extracted. Clinical and radiological factors including fracture classification, interval days from injury to surgery, number of screws, and type of fixation for the posterior pelvic ring were analyzed to evaluate their correlation with closed reduction failure, reduction quality, and fixation failure. Then a logistic regression model was used for statistical analysis to eliminate confusion factors. RESULTS: Ninety-seven patients with displaced posterior pelvic ring fractures were followed for a mean of 1.7 years after surgery. Successful closed reduction and percutaneous fixation were achieved for 89 patients (91.8%), of which 82 patients (92.1%) achieved an excellent or good reduction. Closed reduction failure which converted to open reduction was recorded for eight patients (8.2%). AO/OTA type C3 fracture (p = 0.036) and osteoporosis (p = 0.012) were significant factors for closed reduction failure. Excellent was recorded for 76 patients (78.4%) and acute (1-21 days) interval days from injury to surgery was an associated factor for reduction quality. For AO/OTA type C1 fractures, no more than two short screws (unilateral iliosacral screws) or a single long screw (transiliac-transsacral screws) were independent prognostic factors of fixation failure (p = 0.026). CONCLUSIONS: Displaced posterior pelvic ring fractures treated with the UCRT are associated with excellent/ good radiological results. However, in patients with AO/OTA type C3 pelvic fracture and osteoporosis, the backup plan of open reduction should be routinely prepared. The patient should be brought to the operating room within three weeks to get a good reduction result. Two long screws or one long screw combined with two short screws are required to create a strong construct for AO/OTA type C1 pelvic fractures.

RESUMO

OBJECTIVES: This study aimed to explore risk factors for failure of forearm fracture closed reduction in the pediatric emergency department (ED) and to suggest indications for initial surgery. METHODS: This retrospective cohort study included all patients aged 0 to 18 years who presented to our pediatric ED with an extraarticular forearm fracture treated with closed reduction between May 2017 and April 2021. We explored risk factors for procedural failure, defined as a need for surgical intervention within 6 weeks of the closed reduction attempt. RESULTS: Of 375 patients (median age 8.1 years, 294 [78.2%] boys), 44 (11.7%) patients sustained a reduction failure, of whom 42 (95.5%) had both radius and ulna fractures. Of the 259 patients with fractures of both bones, the following parameters were independent predictors for reduction failure: refracture (adjusted odds ratio [aOR] 17.6, P < 0.001), open fracture (aOR 10.1, P = 0.007), midshaft fracture (aOR 2.6, P = 0.004), radial translation rate 37% and higher in either plane (aOR 5.1, P = 0.004), and age of 10 years and older (aOR 2.9, P = 0.01). CONCLUSIONS: Most pediatric forearm fractures can be successfully managed by closed reduction in the ED. Two-bone fractures had the strongest association with reduction failure. Refracture, open fracture, midshaft location, initial radius bone translation of 37% and higher (and not initial angulation), and patient age of 10 years and older are independent risk factors for reduction failure in two-bone fractures. We propose a risk score for reduction failure that can serve as a decision-making tool.

RESUMO

BACKGROUND: Robot-assisted pelvic fracture closed reduction (RPFCR) positively contributes to patient treatment. However, the current path planning suffers from incomplete obstacle avoidance and long paths. METHOD: A collision detection method is proposed for applications in the pelvic environment to improve the safety of RPFCR surgery. Meanwhile, a defined orientation planning strategy (OPS) and linear sampling search (LSS) are coupled into the A* algorithm to optimise the reduction path. Subsequently, pelvic in vitro experimental platform is built to verify the augmented A*algorithm's feasibility. RESULTS: The augmented A* algorithm planned the shortest path for the same fracture model, and the paths planned by the A* algorithm and experience-based increased by 56.12% and 89.02%, respectively. CONCLUSIONS: The augmented A* algorithm effectively improves surgical safety and shortens the path length, which can be adopted as an effective model for developing RPFCR path planning.

RESUMO

La miotomía selectiva de aductores más la reducción cerrada y Aplicación de yeso pelvipédico forma parte del Gold Standard de tratamiento de la Displasia de cadera. Este tratamiento se realiza usualmente después de un tratamiento fallido con dispositivo abductor de cadera, y que antecede al logro de la marcha independiente, evitando reducciones forzadas y posiciones extremas para disminuir principalmente el riesgo de necrosis avascular de cabeza femoral. El presente trabajo busca determinar factores de riesgo que condicionen el fracaso de la reducción cerrada de cadera en pacientes con displasia del desarrollo de la cadera Se revisaron 12 pacientes, con un total de 14 caderas (2 bilaterales) que se incluyeron en el presente estudio. A todos los pacientes se les realizó miotomía selectiva de aductores más Tenotomía de Psoas y posterior reducción cerrada más Aparato de yeso en primera posición, y posteriormente en Segunda Posición. En el seguimiento a 6 meses posterior a la reducción cerrada: 12 caderas mantuvieron su reducción y desarrollaron índice acetabular normal para la edad, 2 (14%) pacientes presentaron perdida de la reducción, ambos pacientes presentaban índice Acetabular elevados (42 y 39 grados) al momento de la reducción, así como luxación alta de cadera ( IHDI grado IV y Tonnis grado IV).El Índice acetabular óseo elevado, y la luxación alta de cadera ( IHDI y Tonnis grado IV ) son factores de riesgo a tomar en cuenta en la falla de la reducción cerrada de la Displasia del desarrollo de cadera.


Selective adductor myotomy plus closed reduction and pelvipedic cast application is part of the Gold Standard treatment of hip dysplasiañ; following a failed treatment with a hip abductor device, and prior to achieving independent walking; avoiding forced reductions and extreme positions to reduce the risk of avascular necrosis of the femoral head. The present work seeks to determine risk factors in the failure of closed reduction of the hip in patients with developmental dysplasia of the hip. Twelve patients were reviewed, with a total of 14 hips (2 bilateral) that were included in the present study. All patients underwent selective adductor myotomy plus Psoas Tenotomy and subsequent closed reduction plus plaster cast inmovilization in first position, and later in second position.In the 6-month follow-up after closed reduction: 12 hips maintained their reduction and developed normal acetabular index for age, 2 (14%) patients presented loss of reduction, both patients had high acetabular index (42 and 39 degrees) at the time of reduction, as well as high hip dislocation (IHDI grade IV and Tonnis grade IV).High acetabular bone index and high hip dislocation (IHDI and Tonnis grade IV) are risk factors to take into account in the failure of closed reduction of developmental dysplasia of the hip.

RESUMO

RATIONALE: Pipkin III femoral head fracture dislocation (FHFD) is rarely observed in clinical practice, and its outcome is alarming. A considerable proportion of Pipkin III fractures result from repeated or forceful closed reduction of an irreducible FHFD. Pipkin type III fractures pose a therapeutic challenge. Most patients underwent total hip arthroplasty. PATIENT CONCERNS: A 34-year-old man experienced high-energy trauma to the left hip from a terrible traffic accident. Radiography and computed tomography (CT) at the local hospital revealed a left posterior FHFD. Emergency close reduction of the hip was performed.48 hours later, the patient was transferred to our institution. New radiography and CT examinations demonstrated an iatrogenic femoral neck fracture (FNF) associated with FHFD. In addition, a right talar fracture was observed. DIAGNOSIS: Pipkin III fracture combined with contralateral talar fracture. INTERVENTIONS: Considering his Pipkin fracture classification (Pipkin Type-III) and the time to surgery after his injury (>48 hours), the patient underwent left total hip arthroplasty uneventfully, followed by below-ankle plaster cast immobilization for his right ankle. OUTCOMES: At the 6-month follow-up, the patient was able to walk pain-free, and plain radiographs were satisfactory, with no evidence of heterotopic ossification or osteonecrosis of the talus. LESSONS: Before emergency closed reduction, early recognition of the unique characteristics of an irreducible FHFD is essential to avoid iatrogenic femoral neck fracture.

RESUMO

Pediatric forearm and wrist fractures are common; furthermore, some are displaced and require manipulation and reduction. The procedure is commonly performed without real-time image guidance and evaluated radiographically after reduction and casting, leading to multiple reduction attempts and malalignment. Although fluoroscopy can provide real-time assessment of fracture alignment during the procedure, it is not readily available in many emergency departments (EDs) and involves radiation exposure. Ultrasonography is an alternative real-time imaging modality that is inexpensive and readily available. The purpose of this study was to determine whether the use of real-time bedside sonography during closed reduction of distal and middle third forearm fractures can decrease the number of reduction attempts and reduce the number of patients requiring surgery. We compared the results of a conventional blind manipulation, fracture reduction, and casting to fracture reduction under real-time ultrasonographic guidance, in patients treated in our ED between 2014 and 2016. Overall, 458 patients with distal or middle third fractures were included. Of these reductions, 289 were performed without real-time imaging (group 1) and 169 under real-time ultrasound guidance (group 2). In group 1, 10% of patients required re-reduction, and 5% of patients needed surgery. In group 2, only one patient (0.6%) required re-reduction and 1% of patients required surgery due to fracture instability. In conclusion, the current study shows that real-time ultrasound-guided forearm fracture reduction is an effective and inexpensive method for correction of displaced forearm and wrist fractures in children, which does not involve any radiation exposure.

RESUMO

OBJECTIVE: To compare length of stay (LOS) for paediatric patients receiving ketamine sedation or Bier's block anaesthesia for procedural closed fracture reduction. METHODS: We conducted a retrospective audit of paediatric ED patients aged 3-18 years presenting at one of three metropolitan hospitals in Victoria, Australia (2012-2017). Outcomes were post-procedural LOS (PPLOS), total LOS, incidence of ketamine and Bier's block procedures, and recorded adverse effects. Groups were compared using t-tests. Association between treatment group and admission to a short stay unit (SSU) was assessed using univariate logistic regression. RESULTS: Across all three sites, 449 patients were included, 379 of whom received ketamine sedation and 73 of whom underwent Bier's block anaesthesia. Mean age was 9.1 years (ketamine group: 8.3 years; Bier's block group: 13.1 years). Median PPLOS was 75 min shorter for patients who received a Bier's block than for those sedated with ketamine (P < 0.001). Patients sedated with ketamine were also 9.01 times more likely to be admitted to an SSU than those who received Bier's block anaesthesia (95% confidence interval 3.82-21.31, P < 0.001). Ketamine sedation was more common than Bier's block across the three sites. No major adverse events occurred in either group. CONCLUSION: Bier's block anaesthesia is a safe alternative to ketamine sedation for paediatric patients presenting to the ED with closed fractures. It is associated with reduced LOS and need for post-procedural observation. However, ketamine may remain preferable for younger paediatric patients, on whom it places fewer demands for cooperation.

RESUMO

STUDY OBJECTIVE: Temporary lower limb immobilization may be a risk for venous thromboembolism. The purpose of this study was to examine the 90-day incidence of venous thromboembolism among patients discharged from an emergency department (ED) with ankle fractures requiring temporary immobilization. Secondary objectives were to examine individual factors associated with venous thromboembolism in this population and to compare the risk of venous thromboembolism in patients with ankle fractures against a priori-selected control groups. METHODS: This was a retrospective cohort study using province-wide health datasets from Ontario, Canada. We included patients aged 16 years and older discharged from an ED between 2013 and 2018 with closed ankle fractures requiring temporary immobilization. We estimated 90-day incidence of venous thromboembolism after ankle fracture. A Cox proportional hazards model was used to evaluate risk factors associated with venous thromboembolism, censoring at 90 days or death. Patients with ankle fractures were then propensity score matched to 2 control groups: patients discharged with injuries not requiring lower limb immobilization (ie, finger wounds and wrist fractures) to compare relative hazard of venous thromboembolism. RESULTS: There were 86,081 eligible patients with ankle fractures. Incidence of venous thromboembolism within 90 days was 1.3%. Factors associated with venous thromboembolism were older age (hazard ratio [HR]: 1.18; 95% confidence interval [CI]: 1.00 to 1.39), venous thromboembolism or superficial venous thrombosis history (HR: 5.18; 95% CI: 4.33 to 6.20), recent hospital admission (HR: 1.33; 95% CI: 1.05 to 1.68), recent nonankle fracture surgery (HR: 1.58; 95% CI: 1.30 to 1.93), and subsequent surgery for ankle fracture (HR: 1.80; 95% CI: 1.48 to 2.20). In the matched cohort, patients with ankle fractures had an increased hazard of venous thromboembolism compared to matched controls with finger wounds (HR: 6.31; 95% CI: 5.30 to 7.52) and wrist fractures (HR: 5.68; 95% CI: 4.71 to 6.85). CONCLUSION: The 90-day incidence of venous thromboembolism among patients discharged from the ED with ankle fractures requiring immobilization was 1.3%. These patients had a 5.7- to 6.3-fold increased hazard compared to matched controls. Certain patients immobilized for ankle fractures are at higher risk of venous thromboembolism, and this should be recognized by emergency physicians.

RESUMO

Se comparó la osteodesis por técnica lateral de Dorgan con la técnica Cruzada tradicional o de "Banderillero" en fracturas supracondíleas de húmero Gartland II y III. Se realizó un estudio descriptivo correlacional con diseño experimental. Se incluyeron 24 pacientes, los cuales se distribuyeron en 2 grupos: Grupo A (13 pacientes): técnica de Dorgan y Grupo B (11 pacientes): la técnica Cruzada. La mayor frecuencia de pacientes se encontró entre los 10 y 14 años para el Grupo A y 6 a 9 años para el Grupo B. Se encontró predominio del sexo masculino con 78% de los casos. El mecanismo de producción de la fractura más frecuente fue el indirecto. Mayor frecuencia de las fracturas Gartland III en 62,5% casos y desplazamiento posterior en 66,66%. Según los Criterios de Flynn, los resultados post operatorios para el Grupo A: Pérdida del Ángulo de Acarreo: 7,7% Excelente, 53,8% Bueno y 38,5% Regular, y Pérdida de Movilidad: 7,7% Excelente, 38,5% Bueno y 53,8% Regular; para el Grupo B: Pérdida del Ángulo de Acarreo: 54,5% Bueno, 27,3% Regular y 18,2% Malo, y Pérdida de Movilidad: 9,1% Excelente, 81,8% Bueno y 9,1% Malo. La tasa de complicaciones fue de 7,7% para el Grupo A y 18,2% para el Grupo B (p<0,05). La osteodesis con técnica de configuración lateral de Dorgan presentó menor tasa de complicaciones comparada con la técnica Cruzada, sin embargo, ésta última tuvo mejor recuperación de los rangos articulares(AU)


Osteodesis using the Dorgan lateral technique was compared with traditional crossover or "Banderillero" technique in Gartland II and III supracondylar humerus fractures. A descriptive correlational study with experimental design was made. 24 patients were included, and distributed into 2 groups: Group A (13 patients): Dorgan's technique and Group B (11 patients): crossover technique. The highest frequency of patients was found between 10 and 14 years for Group A and 6 to 9 years for Group B. A predominance of the masculine sex was found with 78% of the cases. The most frequent mechanism for producing the fracture was indirect. Higher frequency of Gartland III fractures in 62,5% cases and posterior displacement in 66,66%. According to Flynn Criteria, the postoperative results for Group A: Loss of Motion: 7,7% Excellent, 53,8% Good and 38,5% Fair, and Angle of Movement: 7,7% Excellent, 38,5% Good and 53,8% Regular; for Group B: Angle of load: 54,5% Good, 27,3% Regular and 18,2% Bad, and Angle of Movement: 9,1% Excellent, 81,8% Good and 9,1% Bad. The complication rate was 7,7% for Group A and 18,2% for Group B (p <0,05). Osteodesis with the Dorgan lateral configuration technique presented a lower rate of complications compared to the Cross technique, however, the latter had better recovery of the joint ranges(AU)

RESUMO

ABSTRACT: Lateral humeral condyle fractures in children are treated with several approaches, yet it is unclear which has the best treatment outcomes. We hypothesized that functional outcomes would be equivalent between treatment types, reduction approaches, and fixation types. Our purpose was to assess patient-reported outcomes and complications by treatment type (operative versus nonoperative), reduction approach (open versus percutaneous), and fixation type (cannulated screws versus Kirschner wires).We retrospectively reviewed data from acute lateral humeral condyle fractures treated at our level-1 pediatric trauma center from 2008 to 2017. Patients were included if they were 8 years or older and had completed clinical follow-up. Fractures were categorized by fracture severity as mild (<2-mm displacement), moderate (isolated, 2- to 5-mm displacement), or severe (isolated, >5-mm displacement or >2-mm displacement with concomitant elbow dislocation or other elbow fracture). We extracted data on patient age, sex, treatment type, reduction approach, fixation type, patient-reported outcomes (shortened Disabilities of the Arm, Shoulder, and Hand and Patient Reported Outcome Measurement Information System upper extremity), treatment complications, and follow-up duration. Patients in the operative versus nonoperative group and across fracture severity subgroups did not differ significantly by age, sex, or follow-up duration. Bivariate analysis was performed to determine whether outcomes differed by intervention. Alpha = 0.05.No differences were observed in patient-reported outcomes between operative versus nonoperative groups for the mild and severe fracture subgroups. No differences were observed between approach (open versus percutaneous) or instrumentation (cannulated screw versus Kirschner wire fixation) for any outcome measure within the operative group. Patients whose fractures were stabilized with screws versus wires had significantly higher rates of return to the operating room (94% versus 8.3%, P < .001). The overall complication rate for our cohort was low, with no differences by treatment type or fracture severity.In our cohort, patient-reported outcomes were similar across fracture severity categories, irrespective of treatment or fixation type. Patients who underwent internal fixation with cannulated screws experienced significantly higher rates of return to the operating room compared with those treated with Kirschner wires but otherwise had similar complication rates and patient-reported outcomes.Level of Evidence: 3.

RESUMO

OBJECTIVE: To investigate the curative effect of closed reduction and external fixation in the treatment of grade IV supination-external rotation fractures of the ankle joint. METHODS: Fifty-six patients treated with closed reduction and external fixation from February 2016 to March 2020 were included in this retrospective study, all with sprains. After receiving nerve block anesthesia, the patient underwent closed reduction under C-arm fluoroscopy, and the ankle joint was fixed in a dorsiflexion-inversion position with casting and splints after the end of the fracture met the reduction standard by fluoroscopy. One week and four weeks after the reduction treatment, oblique axial and coronal MR scans of the ankle joint were performed to determine the degree of injury and healing of the inferior tibiofibular syndesmosis; anteroposterior and lateral X-rays of the ankle joint (including the ankle acupoints) were regularly reviewed to observe the fracture alignment and healing. Combined with the images and physical examination, the patients were instructed to undergo ankle weight-bearing rehabilitation training when they met the clinical healing standard, and at the last follow-up, the Mazur ankle evaluation and grading system were used for evaluation. After the reduction, the images were evaluated according to the Leeds standard. The image healing of fracture was evaluated by callus growth criteria. RESULTS: The follow-up period of patients ranged from 11 to 58 months, with an average of 26.8 months. The clinical healing time was (8.51 ± 2.12) weeks. The excellent and good rating after reduction was 82.1%, and the excellent and good rating during clinical fracture healing was 73.2%, according to the Leeds imaging evaluation. According to the Mazur ankle evaluation and grading system, the excellent and good rating was 75.0%. Pairwise comparison of callus images at 4, 6 and 12 weeks showed statistically significant differences (P < 0.05), suggesting callus growth at different time periods. A total of 56 patients had anterior inferior tibial fibular ligament (AITFL) injuries (grade II-III), among which 11 patients had AITFL injuries combined with grade II injuries of the interosseous ligament (IOL) and 4 patients had AITFL injuries combined with grade III injuries of the IOL. CONCLUSIONS: Most of the patients with grade IV supination-external rotation fracture of the ankle joint had good prognosis after closed reduction and plaster combined with splint fixation. For patients with IOL injury who had poor prognosis, open reduction and internal fixation therapy is appropriate.

RESUMO

INTRODUCTION: Forearm fractures are common pediatric injuries. Most displaced or angulated fractures can be managed via closed reduction in the operating room or in the Emergency Department (ED). Previous research has shown that emergency physicians can successfully perform closed reduction within ED; however, the fracture morphology amendable to ED physician reduction is unclear. The aim of this study is to detail the fracture characteristics associated with successful reduction by ED physicians. METHODS: We conducted a retrospective study of children (aged <18 years) presenting to the ED of a tertiary care children's hospital (annual census 90,000) between January 2018 and December 2018 with closed distal and midshaft forearm fractures requiring reduction. Data collected included patient demographics, fracture morphology, management, and complications. Successful ED physician reduction was based on predefined criteria. Orthopedic referrals included those patients sent directly to the operating room, closed reductions performed by orthopedic trainees within the ED, and patients requiring orthopedic consultation after failed ED reduction. RESULTS: A total of 340 patients with forearm fractures were included in the study. ED clinicians attempted to reduce 274 (80.6%) of these fractures and were successful in 256/274 (93.4%) cases. Of the 84 orthopedic referrals, 18 were after failed ED clinician attempt, and 66 were ab initio managed by orthopedics (37 in the operating room and 29 in ED). Compared to the fractures with successful ED reduction (n = 256), factors associated with orthopedic referral (n = 84) included: increasing age, midshaft location, higher degree of angulation, and completely displaced fractures. Angulated distal greenstick fractures were most likely to be successfully reduced by ED clinicians. There were no difference in complication rates between the two groups. CONCLUSION: In this series, fractures most amenable to reduction by ED clinicians include distal greenstick fractures, whereas midshaft and completely displaced fractures are more likely to need treatment by orthopedics.
