Ultrasound-guided techniques for managing length- unstable femoral shaft fractures in children.

OBJECTIVE: The management of length-unstable femoral shaft fractures(LUFSFs) in pediatric patients is still controversial. This study aims to explore the clinical efficacy of ultrasound-guided closed reduction combined with external fixation for treating LUFSFs in children. METHODS: We conducted a retrospective analysis of clinical data from 19 pediatric patients with LUFSFs who underwent ultrasound-guided closed reduction and external fixation between January 2018 and January 2023. Ultrasound was employed not only to facilitate closed reduction of the fracture but also to guide real-time insertion of Schanz pins and monitor pin length as it traversed the opposite cortex. Surgical time, intraoperative fluoroscopy count, hospital stay length, fracture fixation duration, complication incidence, fracture reduction quality at the final follow-up were recorded. RESULTS: The patients' average age was 7.5 years( range: 5 to 11 years). The mean surgical duration was 70.4 min (range: 48-105 min), and the average intraoperative fluoroscopy count was 6.5 (range: 2-16). Fracture fixation lasted an average of 10.9 weeks (range: 7-20 weeks). All patients were followed up for more than one year. 6 cases of superficial pin tract infection occurred, which resolved with oral antibiotics and enhanced needle tract care. No deep infections were observed. Temporary stiffness of the knee joint was observed in 2 patients. According to Flynn's efficacy evaluation system, fracture reduction quality at the final follow-up was rated as excellent in 11 cases and satisfactory in 8 cases, yielding a combined success rate of 100% (19/19). CONCLUSIONS: The technique of ultrasound-guided closed reduction combined with external fixation offers favorable outcomes for children aged 5 to 11 years with LUFSFs, reducing reliance on fluoroscopic guidance.

Ultrasound-guided supraclavicular block versus Bier block for emergency reduction of upper limb injuries: statistical analysis plan.

BACKGROUND: Ultrasound-guided supraclavicular block (UGSCB) is an emerging technique gaining interest amongst emergency physicians that provides regional anaesthesia to the upper limb to tolerate painful procedures. It offers an alternative to the more traditional technique of a Bier block (BB). However, the effectiveness or safety of UGSCB when performed in the emergency department (ED) is unclear. METHODS: SUPERB (SUPraclavicular block for Emergency Reduction versus Bier block) is a prospective open-label non-inferiority randomised controlled trial comparing the effectiveness of UGSCB versus BB for closed reduction of upper limb fractures and/or dislocations. Adult patients presenting with upper limb fracture and/or dislocation requiring closed reduction in ED were randomised to either UGSCB or BB. Once regional anaesthesia is obtained, closed reduction of the injured part was performed and immobilised. The primary outcome is maximal pain experienced during closed reduction measured via a visual analogue scale (VAS). Secondary outcomes include post-reduction pain, patient satisfaction, total opioid requirement in ED, ED length of stay, adverse events and regional anaesthesia failure. RESULTS: Primary outcome analysis will be performed using both the intention-to-treat and per-protocol populations. The between-group difference in maximum pain intensity will be assessed using linear regression modelling with trial group allocation (UGSCB vs BB) included as a main affect. A pre-specified non-inferiority margin of 20 mm on the VAS scale will be used to establish non-inferiority of UGSCB compared to BB. CONCLUSION: SUPERB is the first randomised controlled trial to investigate the effectiveness and safety of UGSCB in the ED. The trial has the potential to demonstrate that UGSCB is an alternative safe and effective option for the management of upper extremity emergencies in the ED.

Arthroscopy-Assisted Closed Reduction and Percutaneous Internal Fixation for Medial Malleolus Fracture.

BACKGROUND: Arthroscopy-assisted closed reduction and percutaneous internal fixation is a minimally invasive technique for medial malleolus fracture treatment. The purpose of the study was to assess the quality and functional outcomes of this technique. METHODS: Seventy-eight patients with combined medial malleolus fractures were treated with arthroscopy-assisted closed reduction and percutaneous screw fixation technique. The surgical procedure was described in detail; the clinical efficacy of this method was evaluated in terms of time of operation, postoperative complications, and fracture healing time; and functional outcomes were analyzed. RESULTS: All of the patients were followed up for a minimum of 12 months without complications of the medial malleolus wound, and all of the medial malleolus fractures healed within 6 to 8 weeks. At the last follow-up, the visual analog scale scores ranged from 0 to 3 and the American Orthopaedic Foot and Ankle Society ankle and hindfoot function scores ranged from 75 to 95. CONCLUSIONS: Arthroscopy-assisted closed reduction and percutaneous internal fixation makes the treatment of medial malleolus fractures less invasive compared with traditional surgical methods and allows simultaneous exploration and management of the articular surface.

Combining robotics and 3D printing facilitates closed reduction of humeral shaft fractures using a minimally invasive plate as a reduction template: A proof-of-concept study.

BACKGROUND: Minimally invasive percutaneous plate osteosynthesis for humeral shaft fractures (HSFs) has limitations due to malreduction and radiation exposure. To address these limitations, we integrated robotics and 3D printing by incorporating plates as reduction templates. METHOD: The innovative technology facilitated closed reduction of HSFs in the operating theatre using 18 models with cortical marking holes. The dataset of the precontoured plate was imported into 3D planning software for virtual fixation and screw path planning. The models were divided into half to simulate transverse fractures. During the operation, the software generated drilling trajectories for robot navigation, and precise plate installation achieved automatic fracture reduction. RESULTS: The evaluation results of reduction accuracy revealed variations in length, apposition, alignment, and rotation that meet the criteria for anatomic reduction. High interoperator reliabilities were observed for all parameters. CONCLUSIONS: The proposed technology achieved anatomic reduction in simulated bones.

Eliminating rote postoperative radiographs for surgically managed pediatric supracondylar humerus fractures.

BACKGROUND: Use of postoperative radiographs after surgical management of supracondylar humerus (SCH) fractures is often based on rote practice rather than evidence. The purpose of this study was to determine the frequency with which 3-week postoperative radiographs at the time of pin removal altered management plans in pediatric SCH fractures that were intraoperatively stable after closed reduction and percutaneous pinning (CRPP). METHODS: We prospectively recruited pediatric patients with SCH fractures managed by CRPP at our institution from June 2020 until June 2022, and reviewed retrospective data on pediatric SCH fractures managed surgically at our institution between April 2008 and March 2015. Patients were assessed for post-CRPP fracture alignment and stability. For prospective patients, we asked clinicians to document their management decision at the 3-week follow-up visit before evaluating the postoperative radiographs. Our primary outcome was change in management because of radiographic findings. RESULTS: Overall, 1066 patients in the retrospective data and 446 prospectively recruited patients met the inclusion criteria. In the prospective group, radiographic findings altered management for 2 patients (0.4%). One patient had slow callus formation and 1 patient was identified as having cubitus varus. Altered management included prolonged immobilization or additional radiographic follow-up. Radiographic findings altered management in 0 (0%) of 175 type II fractures, in 2 (0.9%) of 221 type III fractures, and in 0 (0%) of 44 type IV fractures. We obtained similar findings from retrospective data. CONCLUSION: Rote use of 3-week postoperative radiographs after surgical management of SCH fractures that are intraoperatively stable has minimal utility. Eliminating rote postoperative radiographs for SCH fractures can decrease the time and financial burdens on families and health care systems without affecting patient outcomes.

Refraining from closed reduction of displaced distal radius fractures in the emergency department-in short: the RECORDED trial.

BACKGROUND: With roughly 45,000 adult patients each year, distal radius fractures are one of the most common fractures in the emergency department. Approximately 60% of all these fractures are displaced and require surgery. The current guidelines advise to perform closed reduction of these fractures awaiting surgery, as it may lead to post-reduction pain relief and release tension of the surrounding neurovascular structures. Recent studies have shown that successful reduction does not warrant conservative treatment, while patients find it painful or even traumatizing. The aim of this study is to determine whether closed reduction can be safely abandoned in these patients. METHODS: In this multicenter randomized clinical trial, we will randomize between closed reduction followed by plaster casting and only plaster casting. Patients aged 18 to 75 years, presenting at the emergency department with a displaced distal radial fracture and requiring surgery according to the attending surgeon, are eligible for inclusion. Primary outcome is pain assessed with daily VAS scores from the visit to the emergency department until surgery. Secondary outcomes are function assessed by PRWHE, length of stay at the emergency department, length of surgery, return to work, patient satisfaction, and complications. A total of 134 patients will be included in this study with follow-up of 1 year. DISCUSSION: If our study shows that patients who did not receive closed reduction experience no significant drawbacks, we might be able to reorganize the initial care for distal radial fractures in the emergency department. If surgery is warranted, the patient can be sent home with a plaster cast to await the call for admission, decreasing the time spend in the emergency room drastically. TRIAL REGISTRATION: This trial was registered on January 27, 2023.

The midterm psychological effect of cast removal procedures in children.

OBJECTIVES: This study aimed to compare the course of anxiety change in children who used headphones during cast removal with controls in midterm follow-up. PATIENTS AND METHODS: Sixty-six patients who underwent forearm fracture treatment with closed reduction and long arm casting between June 2021 and March 2023 were retrospectively reviewed. Patients were divided into two groups based on the use of headphones (n=27; 21 males, 6 females; mean age: 8.0±1.8 years; range, 6 to 12 years) or not (n=39; 27 males, 12 females; mean age: 8.9±1.8 years; range, 6 to 12 years) during cast removal with an oscillating saw. Primary outcome measures included preprocedure, postprocedure, and six-month anxiety assessments with the State-Trait Anxiety Inventory. RESULTS: There was an acute increase in the mean state anxiety scores after the procedure, which returned to below baseline at the six-month follow-up in the headphone (31.4±8.3, 33.3±8.7, and 25.1±4.1, respectively) and control groups (34.9±11.1, 37.4±9.5, and 27.3±5.3, respectively). The mean trait anxiety scores before the procedure, after the procedure, and at six months remained similar in the headphone (33.6±3.0, 34.6±3.2, and 32.4±2.8; p>0.05) and control groups (34.1±2.7, 33.7±3.0, and 33.7±3.0, p>0.05). CONCLUSION: This study suggests that the acute anxiety during cast removal did not create anxiety sequelae in the sixth month regardless of headphone use.

Closed reduction and internal fixation for tillaux fractures, based on pre-operative three-dimensional computed tomography.

OBJECTIVE: This study aimed to propose treatment protocol and identify patterns of tillaux fractures using three-dimensional (3D) computed tomography (CT) analysis and to describe an effective reduction technique. METHODS: Forty-two juvenile patients with tillaux fractures were evaluated with 3D-CT scan for fracture displacement pattern and received surgical treatment. Tillaux fragment was reduced by pushing the superomedial quadrant part of the fragment slightly downward towards the ankle joint from anterolateral to posteromedial through 5-mm skin incisions with mosquito forceps. A 4.0 cannulated screw was subsequently inserted from the anterolateral to the posteromedial side parallel to the ankle joint. We analysed the distance and direction of fracture displacement with 3D-CT before the surgery. Pre-operative and post-operative plain radiographs were evaluated. RESULTS: Pre-operative 3D-CT analysis revealed a common fracture pattern, varus tilt, and external rotation of fragment. We achieved satisfactory reduction with residual fracture gaps less than 2 mm in 42 cases. Two cases had a 13-mm anterior gap that was reduced by mini-open reduction because of periosteal impingement. No significant clinical complications were found. CONCLUSION: The closed reduction technique developed based on the fracture pattern identified by 3D-CT anatomical analysis is safe and effective in treating tillaux fractures.

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. LEVEL OF EVIDENCE: Level III, Systematic review of Level-III studies.

Usefulness of the Glove Finger Pad for Ultrasonography in Nasal Fracture Reduction.

The treatment of nasal bone fractures involves closed reduction, in which the reduction position is generally evaluated indirectly by visual examination and palpation. While more direct evaluation methods using ultrasonography can improve treatment outcomes, ultrasonography of the nasal bones requires acoustic coupling materials to hold the entire ultrasonography probe in close contact with the nose. We report the use of the Glove Finger Pad, a homemade acoustic coupling material made from a medical glove. The Glove Finger Pad is easy to prepare and use and produces good images. We believe that the Glove Finger Pad will further enhance the usefulness of ultrasonography for the treatment of nasal fractures.

Dual Joystick Technique for Reduction of Torsional Profile in Pediatric Supracondylar Humerus Fracture With Delayed Presentation.

BACKGROUND: Reduction of some modified Gartland type III and IV supracondylar humerus fractures can pose difficulties, especially if they present late to the hospital. Various techniques of reduction have been tried for reducing the supracondylar humerus fracture for sagittal and coronal plane correction. This retrospective study assesses the dual joystick technique's possible effectiveness in achieving an anatomical reduction of the supracondylar humerus fracture. METHODS: Patients with modified Gartland's type III and IV supracondylar humerus fractures who underwent closed reduction and percutaneous pinning using the dual joystick technique at our trauma center between January 2020 and January 2022 were the subject of a retrospective review. Forty-six patients treated by the above technique who met the inclusion criteria were analyzed at the end of the final follow-up. RESULTS: The mean age of the children was 7.9+/- 2.25 years, with a male predominance at 32:14. The Right upper limb was more involved compared to the left side. The mean injury to hospital presentation was 2.67+/- 1.28 days, and the mean surgical duration was 24.57+/- 13.76 minutes. The average pin spread ratio at the fracture site was 35.17+/- 3.04%. Baumann angle at the final follow-up was 74.83+/- 2.56 degrees. The mean lateral rotation percentage was 2.8+/- 1.3%. 39 patients had excellent cosmetic outcomes, and 42 had excellent functional outcomes, whereas 7 and 4 patients had good cosmetic and functional outcomes, respectively, according to Flynn criteria. CONCLUSIONS: In modified Gartland type III and IV fractures with late presentation where reduction is challenging, this technique is shown to be convenient and easily reproducible and helps accomplish near anatomical reduction with reduced lateral rotation percentage and results in excellent to good outcomes.

Comparison of closed percutaneous screw reduction versus open reduction and internal fixation in the treatment of frontal sinus fractures: A retrospective study.

The aim of this study was to compare closed percutaneous screw reduction to traditional open reduction-internal fixation (OR-IF) for the treatment of anterior table fractures. Both groups were evaluated in terms of operative variables, complications, and treatment success. Of 32 patients included, 19 patients underwent OR-IF, while 13 underwent percutaneous screw reduction. The median operative time, length of hospital stays, and treatment cost of the OR-IF group were 100 min (range 60-130), 4 days (range 3-9), and $727 (range $642-$1291), respectively. The same variables for the closed reduction group were 30 min (range 20-40), 2 days (range 1-2), and $303 (range $252-$349), respectively. The closed reduction group exhibited a shorter operative time (p< 0.001), reduced length of hospital stays (p< 0.001), lower treatment cost (p< 0.001), and a lower complication rate (p = 0.025) compared to the OR-IF group. Late-term outcomes in both groups showed no visible contour changes or step deformities. In conclusion, the percutaneous screw reduction technique is a safe and effective option with minimal morbidity in the treatment of frontal sinus anterior table fractures. Therefore, traditional OR-IF should be reserved for fractures that are not suitable for reduction using minimally invasive techniques.

Positive buttress reduction in femoral neck fractures: a literature review.

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.

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. LEVEL OF EVIDENCE: Level IV-retrospective comparative study.

Does Preoperative Manual Reduction (Omoto Technique) Affect Surgical Outcomes for Calcaneal Fractures? A Multicenter (TRON Group) Retrospective Study.

The Omoto technique is a well-known method that is commonly used for noninvasive manual repair of calcaneal fractures. However, there have been no detailed studies on its clinical outcomes in preoperative closed reduction for surgical cases. This multicenter retrospective study aimed to compare the clinical and radiographic outcomes of calcaneal fractures treated with and without the preoperative Omoto technique, assessing its effectiveness. We extracted 335 patients with calcaneal fracture who underwent surgery between 2015 and 2020 from our multicenter database, named TRON. We evaluated the clinical outcomes using the American Orthopedic Foot and Ankle Society (AOFAS) score, the Böhler angle (BA) for radiographic analysis, and noted any complications. We divided the patients into those managed with the Omoto technique (group O) and those managed without the Omoto technique (group N). Patients were matched by age, sex, and fracture type, resulting in 43 patients per group. The use of the Omoto technique at the time of injury significantly improved the Böhler angle (BA). Furthermore, there were no significant differences in AOFAS, postoperative complications, or BA values at the final follow-up. In conclusion, our study demonstrates that the Omoto technique, when used preoperatively for calcaneal fractures, does not negatively impact the outcomes of subsequent surgical treatments. For patients who prefer to avoid surgery, the Omoto technique can be an effective initial intervention. Additionally, our findings suggest that the Omoto technique may facilitate less invasive surgical options in certain cases.

Closed Reduction for the Treatment of Traumatic Thoracolumbar Spondylolisthesis.

OBJECTIVE: Thoracolumbar traumatic spondylolisthesis is a relatively rare phenomenon and has poor prognosis due to serious spinal cord or cauda equina injuries. In such cases, closed reduction is a method for restoring the vertebral sequence and may play an important role in the treatment process, although whether it is actually feasible for patients with this condition requires further investigation. The present study included 9 patients with serious thoracolumbar traumatic spondylolisthesis to determine the advantages of closed reduction over total reduction through open surgery. METHODS: Data from 9 patients (cases 1-9), diagnosed with severe thoracolumbar traumatic spondylolisthesis between June 2012 and August 2023, were retrospectively reviewed. Five patients were treated with closed reduction in an emergency department and subsequently underwent delayed internal fixation surgery at least 48 hours after the injury, and 4 with similar serious injuries underwent emergency surgery. The incidence of complications and recovery of the spinal cord or cauda equina were compared between groups. RESULTS: There were no significant differences in demographic characteristics or adverse events between the 2 groups. The reduction group had a shorter surgical duration and less blood loss than the surgery group. Although patients in the surgery group may have experienced more pain, there were no significant differences between the groups in Oswestry Disability Index or Japanese Orthopaedic Association scores. Thus, regardless of whether closed reduction was chosen, patients experienced a similar quality of life for a relatively prolonged period. CONCLUSIONS: Closed reduction may be feasible for serious thoracolumbar traumatic spondylolisthesis, although the safety of this method requires further research.
