Low Rates of Hardware Removal and Tendon Rupture for the Acu-Loc 2 Volar Distal Radius Plate: A Minimum One-Year Follow-Up Study.

AIM: Volar locking plates designed for far distal radius fracture fixation can have a significant hardware removal rate and risk of tendon rupture. Plate design has a role in the rate of complications. This study assessed the hardware removal and tendon rupture rate of the Acu-Loc 2 volar distal radius (VDR) plate often used in the treatment of far distal radial fractures. METHOD: We searched our electronic healthcare records system for all patients who had undergone fixation with an Acu-Loc 2 VDR plate (Acumed, Hillsboro, OR, USA) at a tertiary center between January 2017 and December 2021. Patients were excluded if their follow-up time was less than one year or if they could not be contacted by telephone follow-up. Pre-operative radiographs were examined for fracture classification. Follow-up time was defined as the last contact in the clinic or by telephone. RESULTS: A total of 92 patients underwent an open reduction and internal fixation (ORIF) with an Acu-Loc 2 VDR plate. A total of 85 patients met the inclusion criteria for this study. Our cohort included 33 males (38.8%) and 52 females (61.2%). The mean age was 50 years. Twenty-seven fractures (31.0%) were extra-articular, and 60 fractures (69.0%) were intra-articular. The mean follow-up time for the patients was 593.3 days (range 369 to 1185 days). Four patients (4.7%) had their hardware removed. Three (3.5%) patients underwent removal due to tendon irritation and one patient (1.2%) due to a peri-prosthetic fracture around the plate. There were no tendon ruptures recorded. CONCLUSION: The Acu-Loc 2 VDR plate had a low medium-term hardware removal rate and no tendon ruptures. These rates are lower than would be expected when compared with other far distal plate designs.

Glenoid Fracture Fixation Using an Acu-Loc Distal Radius Plate.

Displaced fractures of the glenoid require surgical fixation. This poses multiple problems, including a difficult approach and achieving adequate reduction with current implants. We provide a surgical technical tip for fixing scapula neck and glenoid rim fractures with an Acu-Loc distal radius plate (Acumed, Weyhill, UK), illustrated with two recent case reports. Here, we present two cases of a 58-year-old female and a 51-year-old male presenting to a hospital following a fall, both sustaining an isolated right glenoid intra-articular fracture evident on plain radiographs. CT scans revealed a displaced and fragmented glenoid surface. A reverse Judet posterior approach facilitated exposure to enable the reduction of the glenoid, an uncommon approach. Current plate designs provide surgeons with limited options to fix complex fractures of the scapula and were not suitable here. The lateral scapula border and inferior glenoid have a similar anatomical shape to the distal radius. An Acu-Loc locking distal radius plate with a radial styloid plate was trialled and provided a good reduction to the fragmented glenoid. A distal radius plate can be a useful option to consider in complex scapula neck and glenoid rim fractures. A better understanding of glenoid shape will facilitate the further development of orthopaedic implants. Familiarity with various surgical approaches is needed to operate on these complex fractures.

A mechanistic study on the tolerance of PAM distal end mismatch by SpCas9.

The therapeutic application of CRISPR-Cas9 is limited due to its off-target activity. To have a better understanding of this off-target effect, we focused on its mismatch-prone PAM distal end. The off-target activity of SpCas9 depends directly on the nature of mismatches, which in turn results in deviation of the active site of SpCas9 due to structural instability in the RNA-DNA duplex strand. In order to test the hypothesis, we designed an array of mismatched target sites at the PAM distal end and performed in vitro and cell line-based experiments, which showed a strong correlation for Cas9 activity. We found that target sites having multiple mismatches in the 18th to 15th position upstream of the PAM showed no to little activity. For further mechanistic validation, Molecular Dynamics simulations were performed, which revealed that certain mismatches showed elevated root mean square deviation values that can be attributed to conformational instability within the RNA-DNA duplex. Therefore, for successful prediction of the off-target effect of SpCas9, along with complementation-derived energy, the RNA-DNA duplex stability should be taken into account.

The Efficacy of WALANT Technique in the Management of Distal End Radius Fracture - A Case Series.

Introduction: To improve hemostasis and visibility, a tourniquet was used throughout the majority of hand and wrist procedures, despite the fact that patient experience unnecessary and excruciating pain from the tourniquet. The more current method known as wide-awake local anesthesia without tourniquet (WALANT) enables intraoperative function evaluation while the patient is completely conscious. Materials and Methods: Individuals with displaced distal radius fractures that required surgery and isolated, non-concomitant injuries requiring spinal or general anesthesia were considered for WALANT technique. In our study, five patients underwent dorsal plate fixation and five patients underwent volar plate fixation. Patients receiving dorsal plate fixation required definite dorsal buttress to prevent radiocarpal dislocation. Conclusion: The WALANT technique is a simple, reliable, and effective anesthetic method for internal fixation and open reduction of distal radius fractures. Since a tourniquet is not necessary, the patient is protected from the discomfort and risks associated with one.

Zoledronic Acid Supplementation With Excision of a Giant Cell Tumor of the Distal End Radius to Prevent Recurrence: A Case Report.

Giant cell tumors are benign yet locally aggressive neoplasms commonly observed in the distal radius, exhibiting higher recurrence rates compared to other tumor types. This study presents a case involving a 50-year-old farmer who presented with swelling at the distal end of his wrist. The patient underwent treatment involving intralesional curettage and supplementation with zoledronic acid, resulting in a significant reduction in the tumor's potential for recurrence. This approach aims to achieve an optimal balance between functional outcomes and disease management in the majority of cases. While this strategy proves effective in most instances, there may be scenarios where resection becomes imperative due to the severity of the disease, ensuring adequate disease clearance. In such circumstances, judicious decision-making coupled with an appropriate treatment plan is crucial to guarantee a satisfactory outcome, even in the face of challenges.

Reconstructive Surgical Intervention for Malunited Distal End Radius and Ulna Fracture: A Case Report Demonstrating Improved Patient Outcomes.

This case report explores the efficacy of reconstructive surgical intervention in addressing malunited fractures of the distal end of the radius and ulna. The study presents a detailed analysis of a specific case, highlighting the surgical techniques employed and their impact on patient outcomes. The report emphasizes the importance of precision in addressing malunited fractures and showcases how the intervention led to improved patient outcomes. By documenting this case, the study contributes valuable insights into the field of orthopedic surgery, providing a basis for further research and enhancing the understanding of optimal approaches to managing such complex fractures.

Distal end of a ureteral double-J stent displaced into the contralateral ureter after percutaneous nephrolithotripsy: a case report.

We report displacement of the distal end of a ureteral double-J stent into the contralateral ureter after percutaneous nephrolithotripsy (PCNL) in a 71-year-old man with a history of left kidney stones. Postoperative computed tomography imaging showed that the distal end of the left ureteral double-J stent was displaced into the right ureter, which resulted in persistent right renal colic when the nephrostomy tube was clipped and continuous urine leakage from the nephrostomy opening after the nephrostomy tube was removed. After the cystoscopic adjustment of the ureteral stent, the patient recovered uneventfully and was discharged home the next day.

Radiological Evaluation of Volar Cortical Angle in the Anatolian Population / Evaluación Radiológica del Ángulo Cortical Volar en la Población Anatoliana

SUMMARY: Distal radius fractures are the most common fractures of the upper limb. The most commonly used method in the repair of these fractures is volar locking plates. Recently, the frequency of removal of volar locking plates after surgery has increased. There are many factors in its reduction. Anatomically, incompatibility of the distal end of the radius with volar locking plates is one of them. In previous studies, different volar cortical angle (VCA) values were found in other races. For this reason, this study aimed to determine the mean values by making VCA measurements of the Anatolian population. The study was designed retrospectively. In the study, measurements were made on computed tomography (CT) images of the distal end of the radius of 53 men and 28 women. Radial width, intermediate volar angle, and radial volar angle were measured in the images. On average, the radius width was 23.35±1.96 mm, and the intermediate volar angle was 26.02±.3.83°, radial volar angle was 24±3.07°. Radial width, intermediate volar angle, and radial volar angle differed significantly by gender (p<0.001). A significant correlation was found between radius width, intermediate volar angle, and radial volar angle values (p<0.001). It has been determined that the Anatolian population has a different VCA value than the European, Asian, and other populations. When using volar locking plates in distal radius fracture surgery, volar locking plates should be selected by considering the average values of the races.

Las fracturas del radio distal son las fracturas más comunes del miembro superior. El método más utilizado en la reparación de estas fracturas son las placas de bloqueo volar. Recientemente, ha aumentado la frecuencia de extracción de placas de bloqueo volar después de la cirugía. Existen muchos factores en su reducción y anatómicamente, la incompatibilidad de la extremidad distal del radio con las placas de bloqueo volar es una de ellas. En estudios anteriores, se encontraron diferentes valores del ángulo cortical volar (VCA) en otras grupos. Por esta razón, este estudio tuvo como objetivo determinar los valores medios, realizando mediciones de VCA de la población de Anatolia. El estudio fue diseñado de manera retrospectiva. En el estudio, se realizaron mediciones en imágenes de tomografía computarizada (TC) de la extremidad distal del radio de 53 hombres y 28 mujeres. En las imágenes se midieron el ancho radial, el ángulo volar intermedio y el ángulo volar radial. En promedio, el ancho del radio fue de 23,35 ± 1,96 mm, el ángulo volar intermedio fue de 26,02 ± 3,83° y el ángulo volar radial fue de 24 ± 3,07°. El ancho radial, el ángulo volar intermedio y el ángulo volar radial difirieron significativamente según el sexo (p<0,001). Se encontró una correlación significativa entre los valores del ancho del radio, el ángulo volar intermedio y el ángulo volar radial (p<0,001). Se ha determinado que la población de Anatolia tiene un valor de VCA diferente al de las poblaciones europeas, asiáticas y otras. Cuando se utilizan placas de bloqueo volar en cirugía de fractura de la extremidad distal del radio, las placas deben seleccionarse considerando los valores promedio de los individuos de diferentes grupos.

Is Capitate Shift Reliable as a Single Indicator for Failure of Non-operative Management in Distal Radius Fractures?

Background Distal radius fractures (DRFs) are the most commonly treated fracture; however, their treatment remains controversial. There is significant variation in the rate of surgical intervention related to a lack of consensus regarding the displacement threshold for surgery. Although studies have advocated that carpal malalignment is the most important radiographic parameter for surgical correction, it is rarely considered in general clinical practice and remains poorly studied. Recently, capitate shift was identified as the most useful measure of carpal malalignment, and a capitate shift threshold of -5.98 mm was proposed to indicate surgical intervention. This study aimed to investigate if this threshold is associated with the failure of non-operatively managed DRFs and should be used as a threshold for primary surgical intervention. Methodology A retrospective analysis was performed of all adult patients who underwent closed manipulation and cast immobilisation for DRFs in a UK district general hospital between September 2021 and February 2022. Capitate shift was measured on initial post-casting radiographs using the validated capitate-to-axis-of-radius distance (CARD) by a junior surgeon. The outcome measure was the failure of conservative management, which was defined as the need for repeat intervention (i.e., cast reapplication or surgical fixation) following closed reduction and cast immobilisation. Results A total of 64 patients with 65 DRFs (16 (25%) male, 49 (75%) female) were included in the study. The mean age was 66.6 years (SD = 17.9, 95% CI = 62.2 to 70.9). The mean capitate shift was -1.51 mm (SD = 5.05, 95% CI = -0.28 to -2.73) in all cases (n = 65). The failure rate of DRFs with an 'unacceptable' capitate shift (i.e., equal or less than -5.98 mm) compared to those with an 'acceptable' capitate shift (i.e., greater than -5.98 mm) was 16.7% versus 3.8% (p = 0.09). Conclusions The study concluded that there was no significant association between a capitate shift threshold of -5.98 mm and failure of non-operatively managed DRFs. Given the ease of use and reliability of capitate shift, we advocate for multicentre large cohort studies to identify a threshold for surgical intervention and establish its association with functional outcomes.

A rare case of a male Choledochal Cyst with an ambiguous distal end incidentally discovered in adolescence.

INTRODUCTION AND IMPORTANCE: A choledochal cyst is a rare congenital biliary tract pathology. It displays an evident dilation that could arise in any part along the biliary tree. Its incidence rate reflects its rarity when it takes place in 1 per 100,000-to-150,000 newborns. 75 % of them are detected in early childhood, whereas around 20 % are identified and diagnosed in adulthood. The gender-specific predominance favors females over males with an almost 4:1 ratio. Our case is of an adolescent male, and this constitutes a rare variant of the previous criteria. Furthermore, the distal end of the common bile duct could not be identified. CASE PRESENTATION: We present the case of a 15-year-old previously healthy male, who presented to our surgical clinic complaining of chronic dull aching pain in the right hypochondrium. Preoperative radiological analysis revealed a choledochal cyst. CLINICAL DISCUSSION: Surgical intervention was achieved to excise the lesion and comprehensive histopathological analysis was a key element to establish a definitive diagnosis. CONCLUSION: Choledochal cysts are rare biliary anomalies. Its non-specific symptoms lead to misdiagnosis. Consequently, suitable clinical evaluation escorted by comprehensive radiological imaging is essential to suspect this pathology and swiftly treat it. This anomaly predominantly occurs in females and is chiefly discovered during childhood. Our case is a prime exception to this norm. To the best of our knowledge, this is the first documented case from Syria of an adolescent male affected by a Type I choledochal cyst with an ambiguous end of the distal common bile duct.

Robert Jones bandage versus cast in the treatment of distal radius fracture in children: A randomized controlled trial.

PURPOSE: The present study aimed to treat fractures of the distal end of the radius in children with Robert Jones (RJ) bandage. The objective was to compare this treatment modality with the cast regarding the frequency of the complication occurrence, child comfortability, and family satisfaction. METHODS: The study was a randomized controlled non-inferiority clinical trial including children with recent (less than 5 days) fractures at the distal end of the radius OTA/AO 23-A2, which is usually treated conservatively. Those with open fractures, pathological fracture, severely displaced fracture that needs reduction or multiple injuries were excluded. The participants were divided randomly into 2 groups according to the treatment modalities. Group 1 was treated by plaster of Paris cast (the control group), and Group 2 by modified RJ bandage (the trial group). The difference between the 2 groups was found by the Chi-squared test. The difference was considered statistically significant when the p value was less than 0.05. RESULTS: There were 150 children (aged 2 - 12 years, any gender) included in the study, 75 in each group. The complications occured in 5 (3.3%) cases only, pressure sores of 3 cases in Group 1 and fracture displacement of 2 cases in Group 2. There was no statistically significant difference in the rate of complication occurrence between both modalities of treatment (p = 0.649). Children treated by RJ bandages were more comfortable than those treated by the cast (97.3% vs. 73.3%, p < 0.001) with a statistically significant difference between them. Contrary to that, the families were more satisfied with the cast than RJ bandage (88.0% vs. 81.3%), but without a statistically significant difference (p = 0.257). CONCLUSION: RJ bandage is a non-inferior alternative to the cast for the treatment of fractures at the distal end of the radius that can be treated conservatively in children.

Clinical and Functional Outcomes of Anatomical Plating in Distal Humerus Fractures in Adults.

Background Overall, 2% of all adult fractures are attributed to fractures of the distal humerus, including both supracondylar and intercondylar fractures. According to recent studies, stable fixation with anatomical reduction of intra-articular fragments and early mobilization is required for best outcomes. This study included patients with distal end humerus fractures treated by open reduction and internal fixation (ORIF) with anatomical locking plates and evaluated their clinical outcomes. Methodology This prospective study was conducted at a medical college teaching hospital in southern Rajasthan, India. In total, 20 adult patients with distal end humerus fractures who presented to the orthopedic outpatient department or casualty were admitted. Patients were treated by ORIF with anatomical locking plates, followed up, and evaluated for clinical and functional outcomes. Results Using the Mayo Elbow Performance Score, out of 20 cases, excellent results were noted in five patients, good results in seven patients, fair results in six patients, and poor results in two patients. Conclusions Locking plates are reliable and effective management options for distal humerus fractures. As locking plates are strong and rigid, the period of immobilization can be decreased. Early mobilization helps in preventing joint stiffness and fixed deformity of the joint.

The relationship of distal femur and proximal tibia morphology with anterior cruciate ligament injuries.

PURPOSE: The study aims to determine the correlations between the anatomical structures of the distal femur and proximal tibia associated with the anterior cruciate ligament (ACL). METHODS: Bilateral extremities of 293 patients [143 ACL-ruptured, 150 ACL-intact] (all male) were included in the study. Femoral bi-condylar width (BCW), intercondylar notch width (NW) in the distal femur, proximal tibia width (TW), and tibial eminence width (EW) parameters were measured in the proximal tibia. Indexes are calculated as intercondylar notch width index (NWI) = NW/BCW, tibial eminence width index (EWI) = EW/TW. RESULTS: BCW, NW, TW, and EW measurements were lower in the ACL-ruptured group, but the difference was statistically significant only in the NW (p = 0.009) and TW (p = 0.005) measurements. There was no difference between groups in the NWI. The EWI parameters were calculated higher in the ACL-ruptured group, and the difference was statistically significant (p = 0.02). In both groups, there were very strong correlations between BCW and TW (ACL-ruptured r = 0.820, ACL-intact r = 0.877) and between NW and NWI (ACL-ruptured r = 0.862, ACL-intact r = 0.852), also EW and EWI in ACL-intact group (r = 0.947). CONCLUSIONS: The NW and TW measurements may give an idea about injury risk or prevention in morphological measurements. Correlations also show that the femur and tibia should consider together for ACL injuries.

Enterococcus gallinarum group meningitis after transanal migration of the ventriculoperitoneal shunt: a pediatric case report.

In the literature, only 11 Enterococcus gallinarum group meningitis has been reported so far. The Enterococcus gallinarum group was shown for the first time in a pediatric patient presenting with meningitis after bowel perforation, a complication of a ventriculoperitoneal shunt. A 30-month-old male patient presented with vomiting and fever, with the ventriculoperitoneal shunt distal catheter protruding from the anal orifice. The patient was diagnosed with intestinal perforation and meningitis. Enterococcus gallinarum group bacterial yield in cerebrospinal fluid culture. A total of 6 weeks of intravenous antibiotic treatment was given in the hospital. After the treatment, the patient was re-ventriculoperitoneal shunt and was discharged. Among the shunt complications, meningitis with intestinal perforation is rare. It should be kept in mind that meningitis in such patients may be caused by very rare microbiological factors such as Enterococcus gallinarum group. Antibiotherapy should be given according to the culture result. Then planning should be made for a permanent shunt.

Management of ipsilateral trifocal fracture of the radius-a case report.

Introduction: Diaphyseal forearm fractures are commonly seen in clinical practice. However, segmental forearm fractures are relatively rare. We hereby present a case of surgical management of trifocal fracture of radius (mid-shaft of radius, distal end of radius and neck of radius fracture) with ipsilateral shaft ulna fracture. Case report: A middle aged patient with ulnar shaft fracture and trifocal radius fracture was managed surgically with open reduction and internal fixation of all four fractures. The ulna was addressed first, to achieve alignment, followed by distal radius and shaft radius fixation through the same incision. A separate incision was used to address radial neck fracture. Conclusion: A trifocal radius fracture with ulna shaft fracture has been rarely reported in the literature. Prompt surgical management of the complex fracture led to rapid and satisfactory recovery and good functional outcome for our patient.

The Golden Ratio in Pediatric Wrist Anatomy: A Divine Symmetry.

INTRODUCTION:  The golden ratio, which equals 1.61803…, and is usually defined by the Greek letter φ (phi), has attracted broad attention for a long time. It has been found in many phenomena in the universe including, body symmetry and locomotion. Within this context, the purpose of our study was to evaluate normal morphometric measurements of the wrist in the pediatric population and to identify if phi (φ) is part of the distal radioulnar joint.  Methods: We retrospectively reviewed the hospital records of all skeletally immature patients requiring surgical intervention for distal radius fracture in our unit between January 2010 and January 2017. We define and describe a reproducible method to measure the ratio of the distal radial and ulnar physes. RESULTS:  A total of 268 patients were included with a mean age of 9.41 (3-16) years and a mode of 7 years. Some 63.4% were boys -- 43.3% were right-sided injuries and 56.7% were left-sided injuries. The ratio between the total width of the radial and ulnar growth plates and the radial growth plate closely approximated φ; the mean of this ratio in all the patients included was 1.619684 (1.5848-1.6643). Most of the injuries happened in the summertime, between May and August. CONCLUSION:  We found that the golden ratio exists in our body to play its harmony in the pediatric wrist joint. We believe that with the support of further studies, the golden ratio might yield diagnostic and prognostic implications in the treatment of distal radius/ulnar fractures or abnormalities in this population.

Clinical and Radiological Outcomes of Closed-Loop, Double Button, Coracoclavicular Fixation for Extralateral (Neer Type IIC) Fractures of the Distal Clavicle.

BACKGROUND: The distal end of the clavicle accounts for 10-28% of all clavicle fractures of which 52.8% are considered displaced and require internal fixation due to their high percentage of non-union. Numerous surgical techniques have been described for the well-known Neer types IIA, IIB, and V. Still, the literature is scarce for the rare "extralateral" (type IIC) fracture where the fracture line is located lateral to the completely torn coracoclavicular (CC) ligaments; such small fractures are sometimes not amenable for standard locking plate fixation. METHODS: We present a series of seven patients treated surgically with closed-looped double button CC stabilization via an open approach. There were four males and three females with a mean age of 31 years (range: 19-46 years). The mechanism of injury was a motor vehicle accident in four cases and a fall from height in three cases. The average time from injury to surgery was 2.7 ± 1.3 days and the average follow-up period was 25.7 months (range: 16-48 months). A custom-made, closed-looped, double button device was made using the ProCinch Adjustable Cortical Fixation for anterior cruciate ligament (ACL) (Stryker, Kalamazoo, Michigan) and another standard or slotted button. The fracture was reduced anatomically and the device was tightened and secured with five to six knots. In two cases, additional interfragmentary sutures were used for extra stability. Postoperatively, the arm was immobilized in a simple sling for four weeks; passive assisted elevation up to 90 degrees was allowed from the second postoperative week, followed by active elevation after the sixth postoperative week. Radiological outcomes (bony union, loss of reduction, implant mispositioning, or subsidence of buttons) were assessed using serial plain radiographs. The Constant score (CS) and the Acromioclavicular Joint Instability Score (AJIS) were used for the final clinical evaluation, at least one year postoperatively. RESULTS: Bony union was achieved in all patients at a mean time of 2.7 months (range: 2.5-3.6 months). No cases of delayed union, loss of reduction, button migration, or subsidence were noted. The mean CS was 96.6 ± 3.4 and the mean AJIS score was 94.1 ± 4.7 in a mean follow-up period of 25.7 months (range: 16-48 months). One patient developed a hypertrophic scar and another had mild skin irritation by the suture knots; no other complications were noted except for one patient who developed an early superficial skin infection managed with antibiotics and debridement under local anesthesia. Four patients who participated in sports before injury were able to regain almost full activity seven to nine months after the operation. All were satisfied with the final result. Two patients showed ossification of the CC ligaments with no significant clinical implications. CONCLUSIONS: Although we retrospectively reviewed a small series of patients, we were able to demonstrate a complete rate of fracture union and excellent clinical outcomes with no major complications. Type IIC distal clavicle fractures are rare and require special attention in terms of reduction and optimal fixation. Open CC fixation with closed-looped double buttons is a relatively easy and reproducible technique. We advocate the readjustment of Neer's classification, including "extralateral" fractures as a IIC subtype.

Functional Outcome of Joshi's External Stabilization System Fixation in Distal Radius Fractures.

Background Distal radius fractures account for almost one-sixth of all fractures in a casualty setting. The usual aim of distal radius fracture treatment is to restore the function of the wrist joint, of which the distal radius is an important part. There seems to be no consensus regarding which mode of treatment is optimal for managing distal radius fracture, particularly when it is associated with distal radioulnar joint instability. Objective To describe the functional outcome in patients presenting with displaced distal radius fractures who undergo Joshi's external stabilization system (JESS) fixation. Methods An observational study was done among 32 working-age (18 to 55 years) patients presenting with unilateral displaced distal radius fractures (excluding volar displaced) and subsequently treated with JESS fixation. The outcomes of the patients were assessed using the Green and O'Brien Scoring System modified by Cooney et al. at six months and one year following the surgery. Radiographs were also taken postoperatively and during follow-up. The data were analyzed (using IBM SPSS software version 22 and Microsoft Excel) in terms of the proportion of patients with acceptable clinical and radiological outcomes. Results Acceptable functional outcomes (good and excellent scores in the Green and O'Brien Scoring System) were observed in 78.1% of the study population. Though the functional outcome scores were higher among the younger age group, a statistically significant difference was not obtained. 96.9% of the patients had acceptable radiological reductions, and infection of the pin tracts complicated 9.4% of the cases. A significant improvement in outcome scores (p-value 0.0001) was observed between the outcome scores at six months and one year after surgery. Conclusions JESS fixation is an easy and effective method for treating displaced distal radius fractures to achieve good to excellent clinical outcomes. The functional outcome scores were better in the younger age group and male patients, but no statistically significant difference was observed.

Comportamiento de pacientes con fractura inestable del radio distal tratados mediante fijación externa

RESUMEN Introducción: la fractura del radio distal es una de las entidades traumáticas más frecuentes por la que acuden enfermos a los servicios de urgencia de Traumatología. Aunque su tratamiento es por lo general conservador, existen situaciones en que es necesaria la intervención quirúrgica con la fijación externa. Objetivo: evaluar los resultados de la fijación externa en pacientes con fracturas inestables del radio distal. Materiales y métodos: se realizó un estudio preexperimental en pacientes con fracturas inestables del radio distal, tratados mediante fijación externa en el Hospital Provincial Docente Clínico Quirúrgico Manuel Ascunce Domenech, de Camagüey, entre abril de 2018 y mayo de 2021. La investigación tuvo un nivel de evidencia IV, recomendación D. Resultados: el promedio de edad de los 41 pacientes fue de 40,5 años, con edad mínima de 20 y máxima de 68. Se observó un predominio del sexo femenino (25 pacientes, para un 61 %). La razón sexo femenino-masculino fue de 1,5 a 1, y la de afección de muñeca izquierda-derecha fue de 1,9 a 1. Se encontró significación entre antes y después al emplear los parámetros imagenológicos y las escalas evaluativas, con mejoría en ambos. Conclusiones: la fijación externa en fractura inestable del radio distal resulta eficaz a los doce meses en la mayoría de los enfermos. Las complicaciones son mínimas, y de presentarse responden de forma favorable al tratamiento.

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.
