Radiographic morphometry of the distal end radius in Anatolian population / Morfometría radiográfica del extremo distal del radio en la población de Anatolia

SUMMARY: Distal radius fractures are one of the most common orthopedic injuries encountered by orthopedic surgeons. Correction of dorsal tilt and radial height is essential to restore normal biomechanics of the wrist joint. Comprehensive knowledge of the morphometry of the distal radius of the local population becomes critical for the treating surgeon. This study aims to report the morphometry of the distal radius in the Anatolian population and compare it with similar studies in other races and humans. Radiographs of one hundred and twenty-four people were included in the study. Four radiological parameters were examined on all radiographs: radial height, radial tilt, ulnar variance, and palmar tilt. Radial tilt was 23.35°±1.96; palmar tilt was 15.7°±2,87 radial height (mm) was 10.55±4.34, ulnar variance (mm) was 0.32±1.79. The highest rate of negative ulnar variance was found. According to the study's results, reference data varying by race for anatomical fit should be considered in treating DER injuries.

Las fracturas de la parte distal del radio son probablemente las lesiones ortopédicas más comunes que encuentran los cirujanos ortopédicos. La corrección de la inclinación dorsal y la altura radial es esencial para restaurar la biomecánica normal de la articulación de la muñeca. El conocimiento integral de la morfometría del radio distal de la población local es importante para el cirujano tratante. Este estudio tuvo como objetivo reportar la morfometría de la parte rdistal del radio en la población de Anatolia y compararla con estudios similares en otras razas y humanos. Se incluyeron ciento veinticuatro radiografías simples consecutivas de la articulación de la muñeca. Se examinaron cuatro parámetros radiológicos: altura radial, inclinación radial, variación ulnar e inclinación palmar. El ángulo de inclinación radial fue de 23,35±1,96; el ángulo de inclinación palmar fue de 15,7±, la altura radial (mm) fue de 10,55±4,34, la varianza ulnar (mm) fue de 0,32±1,79. Se encontró la tasa más alta de varianza ulnar negativa (43,5%). Los resultados de este estudio deben tenerse en consideración al tratar fracturas de la parte distal del radio, con datos de referencia que varían según la raza para el ajuste anatómico.

Exploration and consideration on establishing a core outcome set of Traditional Chinese Medicine clinical trials in distal radius fracture / 中国骨伤

There are inconsistencies in treatment outcomes, measurement instruments, and criteria for assessing clinical effectiveness in studies related to distal radius fractures (DRF), resulting in potential biases and failing to provide high-quality clinical evidence. To address these challenges, international researchers have reached a consensus on developing the core outcome indicator set for distal radius fractures(COS-DRF). However, it's important to note that the existing COS-DRF framework could not reflect the unique characteristics of Traditional Chinese Medicine (TCM) treatment. Currently, there are no established standards for treatment outcomes and measurement instruments specific to TCM clinical research, nor has a COS-DRF been established for TCM clinical studies in China. In light of these gaps, our research team aims to construct a core set of treatment outcomes for TCM clinical research on distal radius fractures. This involves compiling a comprehensive list of treatment outcomes and measurement instruments, initially derived from a thorough literature review and expert consensus, which will then undergo further refinement and updates based on real-world clinical experiences, incorporating feedback from 2 to 3 rounds of expert consensus or Delphi questionnaire surveys. Our goal is to establish a COS-DRF or CMS-DRF that aligns with the principles and practices of TCM, and provide high-quality evidence for clinical practice.

Analysis of the causes of soft tissue complications after volar locking plate for the treatment of dorsal displaced distal radius fractures / 中国骨伤

OBJECTIVE@#To investigate the causes of soft tissue complications in patients with dorsal displacement distal radius fractures (DRF) after volar locking plate surgery.@*METHODS@#From July 2016 to May 2021, 112 patients with dorsal displacement DRF were treated with volar locking plate surgery, including 45 males and 67 females. The average age was (46.24±10.08) years old, ranging from 18 to 85 years old. According to whether there were soft tissue complications after operation, they were divided into complication group (40 cases) and non complication group (72 cases). Compared with preoperation, the radial metacarpal inclination and ulnar deflection angle, wrist flexion activity and dorsal extension activity, and grip strength of patients after operation were significantly improved (P<0.05). Compared with the non complication group, the proportion of patients in the complication group whose age was>60 years, body mass index (BMI) more than 30 kg·m-2, smoking, diabetes, fracture type C, open fracture and operation time more than 90 min was higher (P<0.05). The age, BMI, smoking, diabetes, fracture AO classification, fracture type and operation time were analyzed by multifactor Logistic regression to determine the independent risk factors affecting the occurrence of postoperative soft tissue complications of patients, establish a nomogram prediction model, and evaluate the model.@*RESULTS@#At the latest follow-up, the excellent and good rate of wrist joint function recovery was 83.93% (94/112), and the excellent and good rate of fracture reduction was 84.82% (95/112). Multivariate Logistic regression analysis showed that age more than 60 years old, diabetes, fracture type C, open fracture and operation time more than 90 min were independent risk factors for postoperative soft tissue complications (P<0.05). The receiver operating characteristic (ROC), calibration curve and clinical decision curve of the nomogram prediction model showed discrimination, accuracy and validity were good.@*CONCLUSION@#Age more than 60 years, diabetes mellitus, fracture type C, open fracture, and operation time more than 90 min are all independent risk factors for soft tissue complications after DRF volar plate fixation. In clinical treatment, perioperative soft tissue management should be done in such patients to prevent complications.

Short-term efficacy of digitally-assisted traditional Chinese medicine manual reduction combined with 3D printed splint in the treatment of AO type-A distal radius fractures / 中国骨伤

Objective To explore the short-term efficacy of digitally-assisted traditional Chinese medicine manual reduction combined with 3D printed splint in the treatment of AO type-A distal radius fractures, and explore the quantification of traditional Chinese medicine manual reduction and personalized improvement of splinting. Methods The clinical data of 50 patients with AO type-A distal radius fractures, who received treatment at the outpatient department of Cangzhou Integrated Traditional Chinese and Western Medicine Hospital in Hebei Province, were retrospective analyzed. The patient cohort included 22 females and 28 males, with ages ranging from 25 to 75 years old. Among them, 27 cases presented with distal radius fractures on the left side, and 24 cases on the right side. The patients were categorized into two groups: treatment group (n=25) and control group(n=25). There were 13 males and 12 females in the treatment group, with an average age of (56.2±5.5) years old. Treatment approach for this group involved several steps. Initially, Mimics Research software was used to conduct comprehensive analysis of complete CT data from the affected limb, resulting in the creation of a three-dimensional model. Subsequently, 3D models of the bones and skin contours, stored as STL format files, were imported into the Materialise Magics 23.0 software for model processing and repair. This facilitated the simulation of reduction and recording of displacement data, effectively generating a "digital prescription" to guide and quantify traditional Chinese medicine manipulation procedures. Finally, a personalized 3D printed splint was applied for fixation treatment. There were 15 males and 10 females in the control group, with an average age of (53.32±5.28) years old. These patients were treated with manualreduction combined with traditional splinting. The clinical efficacy of the two groups was assessed in terms of fracture reduction quality, fracture healing time, Gartland-Werley wrist joint score and X-ray parameters (palminclination angle, ulnar deviation angle, radius height) at 6 weeks post-operatively. Results The treatment group exhibited a shorter duration for achieving clinical healing compared to the control group (P<0.05). Six weeks post-operatively, the treatment group demonstrated higher wrist joint function scores, and a higher proportion of excellent and good outcomes than the control group(P<0.05). The treatment group was superior to the control group in terms of imaging parameters 6 weeks post-operatively (P<0.05). Conclusion By quantifying skin contours through digital simulation prescription reduction, a personalized 3D printed splint is developed to effectively stabilize fractures, enhancing localized fixation while ensuring greater adherence, stability, and comfort. This innovative approach offers personalized treatment for AO type-A distal radius fractures and presents a novel, precise treatment strategy for consideration.

Concomitant Ulnar Styloid Fractures in Distal Radius Osteosynthesis Does Not Impact Radiographic Outcomes, Ulnar Sided Symptoms and Patient Outcomes

@#Introduction: Current literature reports varied significance of ulnar styloid fractures (USF) associated with distal radius fractures. Our study assesses the role of ulnar styloid fractures and fragment size in surgically managed distal radius fractures. Materials and methods: We reviewed patients who underwent surgical fixation of distal radius fractures between January 2004 to June 2006. Patients were divided into those with (Group 1) and without (Group 0) USFs. Post-operative radiographic parameters, clinical outcomes and overall wrist function were analysed. Outcomes included ulnar-sided wrist pain, extensor carpi ulnaris (ECU) tendinitis, triangular fibrocartilage complex (TFCC) grind test, distal radioulnar joint (DRUJ) instability and pain. Overall wrist function was assessed with range of motion and Disabilities of the Arm, Shoulder and Hand (DASH) score. Results: Our study cohort included 31 males and 23 females, and 38.9% of these patients had concomitant USFs. There was no difference in terms of demographic data and fracture configuration between groups. Radiographic parameters were similar, except for palmar tilt, which was significantly higher in Group 1 (4.6º vs 9.4º, p=0.047). At 24 months, there were no differences in clinical outcomes and overall wrist function. A sub-group analysis showed that mean USF fragment size was larger in patients with a positive TFCC grind test (3.9mm vs 7.3mm, p=0.033). Conclusion: The presence of USFs in surgically managed distal radius fractures does not compromise clinical and functional outcome. Similarly, the size of USFs does not impact clinical and functional outcome but is associated with the presence of a positive TFCC grind test.

Comparison of above elbow and below elbow immobilisation for conservative treatment of distal end radius fracture in adults: A systematic review and meta-analysis of randomized clinical trials / 中华创伤杂志(英文版)

PURPOSE@#The aim of this study was to analyze if any difference exists on the type of immobilisation (above elbow vs. below elbow) in the conservative treatment of distal end radius fractures in adults.@*METHODS@#The study was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses. An electronic literature search was performed up to 1st October 2021 in Medline, Embase, Ovid and Cochrane database using the search terms, "distal end radius fractures OR fracture of distal radius", "conservative treatment OR non-surgical treatment", "above elbow immobilisation" and "below elbow immobilisation". Randomized clinical trials written in English, describing outcome of distal end radius fractures in adults by conservative or non-surgical means using above elbow immobilisation or below elbow immobilisation were included and assessed according to the risk of bias assessment (RoB2) tool by Cochrane collaboration. Non-randomized clinical trials, observational studies, retrospective studies, review articles, commentaries, editorials, conference presentations, operative techniques and articles without availability of full text were excluded from this review. The meta-analysis was performed using Review Manager version 5.4.1 (The Cochrane Collaboration, Copenhagen, Denmark).@*RESULTS@#Six randomized clinical trials were included for quantitative review. High heterogeneity (I2 > 75%) was noted among all the studies. The standard mean difference (MD) between the disability of the arm, shoulder and hand scores in both the groups was 0.52 (95% CI: -0.28 to 1.32) which was statistically non-significant. There was no statistical difference in the radial height (MD = 0.10, 95% CI: -0.91 to 1.12), radial inclination (MD = 0.5, 95% CI: -1.88 to 2.87, palmar tilt (MD =1.06, 95% CI: -0.31 to 2.43) and ulnar variance (MD = 0.05, 95% CI: -0.74 to 0.64). It was observed that shoulder pain occurred more commonly as a complication in above elbow immobilisation and the values were statistically significant (above elbow: 38/92, 41.3%; below elbow: 19/94, 20.2%).@*CONCLUSION@#This two-armed systematic review on the above elbow or below elbow immobilisation to be used for conservative treatment of the distal end radius fracture in adults resulted in non-significant differences in terms of functional and radiological scores among the 2 groups but significant increase in the complication rates in the above elbow group.

Clinical application of special fluoroscopy method in the treatment of distal radius fractures with volar locking plate / 中国骨伤

OBJECTIVE@#The relationship between the distal screws and the wrist articular surface was assessed by the additional lateral oblique fluoroscopic view during the operation, and the dorsal tangential view of the wrist was used to observe whether the distal screw penetrated the dorsal cortex, so as to evaluate the clinical efficacy of the volar locking plate in the treatment of distal radius fractures.@*METHODS@#From January 2020 to June 2021, 45 cases of fresh distal radius fractures were treated using the volar Henry's approach, including 20 males and 25 females, aged from 32 to 75 years old with an average of (52.4±8.1) years old. During the operation, they were divided into 2 groups according to the different intraoperative fluoroscopic views:the control group of 20 cases, treated with standard anteroposterior and lateral fluoroscopic view;25 cases in the observation group, additional lateral oblique fluoroscopic view and dorsal tangential view of the wrist were taken. The wrist joint function score and postoperative complications were evaluated at 6 weeks, 3 and 6 months after operation between two groups.@*RESULTS@#All 45 patients were followed up and the duration ranged from 6 to 14 months, with an average of (10.8±1.7) months, all patients achieved bone union and the incision healed well. The incidence of postoperative complications in the observation group was lower than that in the control group, and the difference was statistically significant (P<0.05). In terms of Gartland-Werley score of wrist joint function, the score of wrist function in the observation group was (4.58±1.31) at 6 weeks, (2.98±0.63) at 3 months and (1.95±0.65) at 6 months post-operatively, which were better than those in the control group (6.32±1.96) at 6 weeks, (3.63±0.76) at 3 months and (2.43±0.73) at 6 months. The difference was statistically significant (P<0.05). In the observation group, 7/25 cases(28%) were found to have screw penetration during the operation by additional lateral oblique and dorsal tangential radiograph fluoroscopic views of wrist.@*CONCLUSION@#The addition of lateral oblique and dorsal tangential during the operation could improve the accuracy of distal screw placement, reduce postoperative complications, and achieve early functional exercise.

Reproducibilidad de parámetros radiográficos para determinar el éxito quirúrgico de fracturas de radio distal / Reliability of radiographic parameters to determine the surgical success in distal radius fractures

Resumen: Introducción: las fracturas del radio distal son las más comunes en extremidades superiores. Estandarizar las mediciones radiográficas para su abordaje quirúrgico es importante. Este estudio midió la reproducibilidad intra/interobservador de parámetros radiográficos asociados al éxito quirúrgico en estas fracturas. Material y métodos: diseño transversal retrospectivo con datos secundarios de expedientes clínicos. Se evaluaron radiografías de 112 fracturas en planos posteroanterior y lateral por dos traumatólogos estandarizados en toma de mediciones para calcular cinco parámetros indicativos de éxito postquirúrgico: altura radial, inclinación radial, inclinación volar, varianza cubital y escalón articular. La reproducibilidad de distancias y ángulos se evaluó con el método de Bland-Altman calculando: diferencia media entre mediciones, rango a ± 2 DE y proporción de mediciones fuera de ± 2 DE. El éxito postquirúrgico se comparó en pacientes con/sin obesidad según la media de las dos mediciones de cada evaluador. Resultados: el evaluador 1 tuvo la mayor diferencia intraobservador en altura radial (0.16 mm) y la mayor proporción fuera de ± 2 DE en varianza cubital (8.1%); el evaluador 2 tuvo la mayor diferencia en inclinación volar (1.92o) y la mayor proporción en inclinación radial (10.7%). La mayor diferencia interobservador fue en varianza cubital (1.02 mm) y la mayor proporción fuera de ± 2 DE en altura radial (5.4%). La inclinación radial tuvo la mayor diferencia (1.41o) con 4.5% de mediciones fuera de ± 2 DE. La varianza cubital y la inclinación volar tuvieron la mayor diferencia de éxito postquirúrgico entre evaluadores, sobre todo en pacientes con obesidad. Conclusión: mejorar la calidad radiográfica y estandarizar las mediciones resulta en indicadores más reproducibles.

Abstract: Introduction: distal radius fractures are the most common in upper extremities. Therefore, it is important to standardize radiographic measures for their surgical approach. This study assessed the intra/interobserver reproducibility of radiographic parameters associated with surgical success of distal radius fractures. Material and methods: retrospective cross-sectional design of secondary data extracted from clinical records. Posteroanterior and lateral X-rays of 112 distal radius fractures were assessed by two trauma specialists standardized in the measurements required to compute five parameters indicative of postoperative success: radial height, radial inclination, volar tilt, ulnar variance, and articular stepoff. The reproducibility of distances and angles was evaluated using the Bland-Altman method, calculating the mean of the difference between measurements, the range at ± 2 SD, and the proportion of measurements outside ± 2 SD. Postoperative success was also compared between patients with and without obesity according to the mean of the two measures made by each evaluator. Results: evaluator 1 had the largest intra-observer difference in radial height (0.16 mm) and the largest proportion outside ± 2 SD in ulnar variance (8.1%); evaluator 2 had the largest difference in volar tilt (1.92o) and the highest proportion in radial inclination (10.7%). The largest inter-observer difference was for ulnar variance (1.02 mm) and the largest proportion outside ± 2 SD. for radial height (5.4%). Radial tilt had the largest difference (1.41o) with 4.5% of measurements outside ± 2 SD. Ulnar variance and volar tilt had the largest difference in postoperative success between evaluators, especially in patients with obesity. Conclusion: improving the radiographic quality and standardizing the measurements results in more reproducible indicators.

ABSTRACT Introduction: distal radius fracture is one of the most frequent traumatic entities due which patients come to Traumatology emergency services. Although their treatment is usually conservative, there are situations where surgery with external fixation is necessary. Objetive: to evaluate the results of external fixation in patients with unstable distal radius fractures. Materials and methods: a pre-experimental study was carried out in patients with unstable fractures of the distal radius treated by external fixation at the Provincial Clinical Surgical Teaching Hospital Manuel Ascunce Domenech, of Camagüey, between April 2018 and May 2021. The research has IV level of evidence, D recommendation. Results: the average age of the 41 patients was 40.5 years old, with minimum age of 20 and maximum age of 68 years. Female sex prevalence was observed (25 patients, 61%). The female-male sex ratio was 1.5 to 1, and the left-right wrist condition was 1.9 to 1. Significance was found between before and after using the imaging parameters and the evaluative scales, with improvement in both cases. Conclusions: external fixation in unstable distal radius fracture is effective at twelve months in most patients. Complications are minimal and if they are present, they favorably answer to treatment.

Management of Comminuited Intra/Juxta Articular Fracture of Distal Radius Using Bridging External Fixator

Background: Distal radius fractures are the third most common osteoporotic fractures and are frequently treated in emergency department. They have a trimodal peak of occurrence and there has been a significant increase in incidence of involvement in elderly females and young males. Management of these fractures comes with lots of treatment options and challenges to provide good functional outcome. This prospective study was done for the management of communited intra/juxta articular fractures of distal end radius using a bridging external fixator on 25 patients. The principle of ligamentotaxis was used for alignment of fracture fragments and wrist spanning external fixator was used to maintain the fracture reduction.Methods:25 patients of either sex with age group 16 to 80 years were taken from the orthopedic department. After proper primary care, cases were classified using Fernandez classification, and posted for surgery as soon as investigations and fitness were taken.Results:Patients involved in the study were in range of 16 to 78 years with 16 patients having dominant side with road traffic accident as leading cause.Radiological union was seen at an average of 7.3 weeks, 4 patients had superficial pin tract infection, 3 patients had stiffnes and a single case had malunion. Conclusions:Modified clinical scoring system of Green and O払rien was used to evaluate the overall functional results which showed excellent to good results in 84% of cases. Hence, properly planned and executed bridging external fixator is an easy, cost-effective and reliable treatment modality through the 揚rinciple of Ligamentotaxis�.

Clinical efficacy of ultrasound-guided closed reduction for pediatric distal radius fracture / 中华实用儿科临床杂志

Objective:To compare the clinical efficacy of ultrasound-guided closed reduction and bare-handed reduction on pediatric distal radius fractures.Methods:Clinical data of 118 consecutive pediatric patients with distal radius fracture treated in the Wuhan Children′s Hospital, Tongji Medical College, Huazhong University of Science & Technology from April 2018 to August 2019 were retrospectively analyzed.Patients treated with bare-handed reduction and ultrasound-guided closed reduction were respectively classified into group Ⅰ (58 cases) and group Ⅱ (60 cases). Baseline characteristics, treatment duration, out-patient treatment cost, postoperative pain and the modified Mayo wrist function score during the follow-up visits between groups were compared by the t test.The success rate of initial reduction, reduction times, hospitalization rate and complication between 2 groups were compared by the Chi- square test.The number of postoperative imaging scans between 2 groups was compared by the Mann- Whitney U test. Results:There were no significant differences in out-patient treatment cost and hospitalization rate between 2 groups (all P>0.05). There were significant differences in the length of stay [ (166.2±54.8) min vs.(142.6±49.2) min], success rate of initial reductions [72.4%(42/58 cases ) vs.88.3%(53/60 cases)], incidence of repeated reductions (27.6% vs.1.7%) and the incidence of postoperative repeated imaging scans (20.7% vs.1.7%) between groupⅠ and group Ⅱ (all P<0.05). A total of 104 patients (88.1%) were successfully treated with closed reduction and followed up, with a rate of success reductions.Among them, success rate of closed reduction in group Ⅰ and Ⅱ were 86.2% and 90.0%, respectively.The mean time of fracture healing was 43 (34-56) days.There were no significant differences in fracture healing time and pain score between 2 groups(all P>0.05). The modified Mayo wrist score was significantly lower in group Ⅰ than that of group Ⅱ[(97.3±4.1) points vs.(98.8±2.9) points, P<0.05]. Seven patients in group Ⅰ suffered fracture re-displacement, including 6 cases within 1 case week and 1 within 2 weeks, and 4 cases admitted to the surgical ward for further management.Five patients in group Ⅱ had re-displacement within 1 week of plaster fixation, of which 2 cases admitted to the surgical ward for further management, which was comparable between groups( P>0.05). Conclusions:Both ultrasound-guided closed reduction and bare-handed reduction are effective on the treatment of pediatric distal radius fractures, showing low incidence of complications and satisfactory functional results.Owing to its higher success rate of initial reduction, lower frequency of postoperative ra-diography and shorter length of stay, ultrasound-guided closed reduction should be recommended.

Comparison of functional recovery of distal radius fracture by suture of pronator muscle through modified Henry approach / 中国骨伤

OBJECTIVE@#To investigate the effect of suture of pronator muscle on forearm function after modified Henry approach for distal radius fractures.@*METHODS@#from January 2018 to December 2020, 220 patients with distal radius fractures were treated with open reduction and locking plate internal fixation through the modified Henry approach. They were divided into two groups according to different suture methods. There were 112 cases in the intraoperative suture group, including 35 males and 77 females;The age ranged from 37 to 65(48.5±7.4) years;AO classification of fracture, 46 cases of type B and 66 cases of type C;After fracture reduction and locking plate fixation, the pronator muscle was opened and sutured. There were 108 cases in the non suture group, 32 males and 76 females;The age ranged from 34 to 67(47.6±7.8) years;There were 41 cases of fracture type B and 67 cases of fracture type C;After fracture reduction and locking plate fixation, the open pronator muscle was not sutured, and it was laid on the surface of the plate in situ. The range of wrist motion (pronation, supination, palmar inclination and dorsiflexion), the score of disability of arm shoulder and hand dash and visual analog scale(VAS) were compared between the two groups at 6 weeks and 6 months after operation.@*RESULTS@#All 220 patients were followed up for 6 to 18 (8.5±1.3) months. There was no significant difference in the range of motion and DASH score of forearm and wrist between the two groups 6 weeks after operation (P>0.05);There was significant difference in VAS score between suture group (2.6±1.2) and non suture group (5.8±2.3)(P<0.05). Six months after operation, there was no significant difference in the range of motion, DASH score and VAS score of forearm and wrist between the two groups(P>0.05).@*CONCLUSION@#The modified Henry approach has no obvious advantages in the range of wrist movement and upper limb function, but the intraoperative suture of pronator can reduce the early postoperative pain. It is suggested that the pronator should be sutured during the operation.

The Relation between the Radial Collapse and the Number of Metaphyseal Screws for Distal Radius Fractures

@#Introduction: The purpose of this study is the evaluation of radial collapse, based on the number of screws used in the metaphyseal region and by distal dorsal distance (DDD) and lunate facet distance (LFD) measurement. Materials and methods: Between 2015 and 2019, 60 patients who were being treated with volar locking plates due to isolated distal radius fracture were evaluated. Control radiographs were taken on the first day and at 3rd-, 6th- and 12th-month follow-ups. Distal dorsal cortex distance and lunate facet distance were measured in the lateral radiographs. The number of screws used in the metaphyseal region was also evaluated. According to the number of screws, the amount of collapse was analysed based on both the LFD and the DDD. Results: The mean age of patients was 43.5±12.7 years. Thirty-three of the patients included in the study were male and 27 were female, and the minimum follow-up period was one year. According to the mean number of screws, groups were defined as up to 6 screws or 7 screws and above. There was a statistically significant difference between the groups in terms of DDD collapse at the 6th-month and 12th-month follow-ups (p<0.005). It was observed that the radial collapse and decrease in DDD and LFD were lower in plates with seven screws and above. Conclusion: Decreases in either DDD or LFD, or radial collapse were observed less in patients who had seven or more metaphyseal screws inserted. These findings might be useful for surgeons treating distal radius fractures to reduce radial collapse.

Surgical reconstruction for injury to the distal radius: progress in clinical application / 中华创伤骨科杂志

The distal radius and the proximal row of carpal joints are important components of the carpal joint. Injury to the distal radius may result in decreased range of motion and strength of the wrist, and changes in the wrist appearance can hurt the patients. Developing microsurgical techniques, and updating orthopedic metal instruments and bone biological products provide more possible means for surgical reconstruction. Currently, reconstruction of the distal radius with autologous bone grafting is the mainstream surgical method, and the fibula and ilium are the main options for grafting. Moreover, other repair methods have also been reported, such as prosthetic repair and repair using the ulna to replace the radial function. This article reviews the main forms of surgical repair and reconstruction after distal radius injury reported in recent years, compares the clinical effects of different surgical methods, and summarizes the advantages and disadvantages of each surgical method, hoping to provide useful information for the treatment of distal radius injury.

Functional outcome of displaced intra-articular fractures of the distal radius: Comparison of closed reduction percutaneous pinning with or without external fixation versus open reduction plate fixation

OBJECTIVES@#The purpose of the study was to determine the outcomes of closed reduction percutaneous pinning (CRPP) with or without external fixation (EF) with open reduction and internal fixation (ORIF) using plate and screws. @*METHODS@#Outcomes of ORIF versus CRPP, with or without external fixation for intra-articular distal radius fractures were compared through a multicenter, non-randomized, ambispective cohort study. A validated Filipino version of the DASH score (FIL-DASH) was used as primary outcome measure.@*RESULTS@#The ORIF group consisted of 13 patients and the CRPP group, eight patients. Pain scores, post-operative complications and radiographic measurements were also evaluated. Mean FIL-DASH score for the ORIF group (M=26.69, SD=4.88) was significantly higher versus the CRPP group (M=14.59, SD=10.64; t(19)=3.58, p=0.002). No significant differences in radiologic parameters, pain scores, and complications were found.@*CONCLUSION@#The study demonstrates that functional outcomes post-CRPP with or without external fixation compares favorably over ORIF for distal radius fractures at one-year post-surgery.

Validity and reliability of image intensifier articular step-off and gap measurements for distal radius fractures using a cadaveric model

OBJECTIVES@#The purpose of this study was to determine the accuracy and reproducibility of image intensifier (fluoroscopic) measurements of gap and step-off displacements on the articular surface of the distal radius using a standard cadaver osteotomy fracture model.@*METHODS@#Fourteen orthopedic residents were randomly assigned using the fish bowl method to measure the gap and step-off displacements in cadaveric fluoroscopic images using a digital caliper. Each physician was randomly assigned the images where they examined the images twice and the average taken using a standard technique. The interobserver and intra-observer reliability were calculated using the intraclass correlation coefficient (ICC). Rank Sum test was used to evaluate the validity of measurements.@*RESULTS@#The results of the study showed that there was no significant difference between the cadaveric and measured step-off and gap displacements. Intraclass correlation coefficient scores showed moderate (0.41) to perfect (1.0) agreement.@*CONCLUSION@#The study showed that fluoroscopy can aid in the interpretation of gap and step-off displacements in acute distal radius fractures.

Estudio comparativo entre fijador externo versus placa volar de estabilidad angular en las fracturas de radio distal / External fixator versus angular stability volar plates in distal radius fractures. A comparative study

Las fracturas del radio distal están entre las patologías más comunes en el área de la emergencia, actualmente los tratamientos más utilizados son la fijación con alambres de Kirschner y fijador externo (AKFE), o la osteosíntesis con placas volares de estabilidad angular (PVEA), realizamos un estudio comparativo de los resultados a corto plazo entre ambos métodos. Se realizó un estudio transversal, retrospectivo y descriptivo desde el 2005 al 2019, donde se revisaron las historias de los pacientes con fracturas de radio distal tratados con AKFE o PVEA, evaluando el alta después de la medición de la amplitud de movimiento articular funcional. Se incluyeron 68 pacientes, 47(69,11%) pacientes tratados con PVEA y 21(30,88%) con AKFE, la edad promedio fue de 53,07 años, la causa más común fue la caída de su altura en 60,29% casos, el alta médica por mejoría se realizó a las 15,95 semanas para AKFE y a las 9,86 semanas para PVEA (<0.05). La osteosíntesis con PVEA evidenció un menor tiempo de recuperación de la amplitud de movimiento articular con respecto a los pacientes tratados con AKFE(AU)

Fractures of the distal radius are among the most common pathologies in the emergency area, currently the treatment more frequently used are fixation with Kirschner wires and external fixator (KWEF), or osteosynthesis with angular stability volar plates (FAVP), we carried out a comparative study of the short-term results between both methods. This is a cross-sectional, retrospective and descriptive study from 2005 to 2019, where the histories of patients with distal radius fractures treated with KWEF or FAVP revised, evaluated, evaluating at discharge after functional joint range of motion was measured.68 patients were evaluated, 47 patients treated with FAVP and 21 with KWEF, average age of 53.07 years, the most common cause was the fall from his height with 60.29%, the medical discharge was made at 15,95 weeks for KWEF and 9,86 weeks for FAVP; with a t student<0.05 between them. Osteosynthesis with FAVP evidenced a shorter recovery time for joint range of motion compared to patients treated with KWEF(AU)
