Comparison of the therapeutic efficacy of hip arthroplasty and proximal femoral nail antirotation internal fixation for unstable intertrochanteric femur fractures.

OBJECTIVE: To compare the therapeutic efficacy of total hip arthroplasty (THA) versus proximal femoral nail antirotation (PFNA) internal fixation for treating unstable intertrochanteric femur fractures (UIFF). METHODS: In this retrospective study, the clinical data of 86 patients with intertrochanteric femur fractures (IFF) treated in Hangzhou Fuyang Hospital of Orthopedics of Traditional Chinese Medicine from January 2022 to December 2023 were collected and analyzed. Patients were categorized into two groups based on their treatment modality: the THA group (n=45, treated with THA) and the PFNA group (n=41, treated with PFNA internal fixation). The two groups were compared in terms of surgery-related indicators (operative time, incision length, intraoperative blood loss, postoperative drainage volume, and intraoperative fluoroscopy frequency), postoperative recovery indicators (time to first ambulation, length of stay, time until full weight-bearing ambulation), and the incidence of postoperative complications. The pain indicators (Wong-Baker Faces Pain Rating Scale) and hip joint function indicators (Harris Hip Scores) of patients in the two groups were assessed preoperatively and at 1, 3, and 6 months postoperatively. The hip joint function recovery outcomes of the two groups of patients were recorded at the last follow-up. RESULTS: The PFNA group had significantly shorter operative time, shorter incision length, lower intraoperative blood loss, lower postoperative drainage volume, and higher intraoperative fluoroscopy frequency compared to the THA group (all P < 0.05). The PFNA group also had significantly longer time to first ambulation, length of stay, and time until full weight-bearing ambulation (all P < 0.05). There was no statistically significant difference in the incidence of postoperative complications between the two groups (P > 0.05). Postoperative Wong-Baker scores in both groups decreased compared to preoperative levels. At 1 and 3 months postoperatively, the PFNA group had significantly higher Wong-Baker scores than the THA group (P < 0.05), but at 6 months postoperatively, the difference was not statistically significant (P > 0.05). Postoperative Harris scores increased in both groups compared to preoperative scores. At 1 month postoperatively, the PFNA group had significantly lower Harris scores than the THA group (P < 0.05); however, at 3 and 6 months postoperatively, the differences were not statistically significant (all P > 0.05). There was no significant difference in the rates of excellent recovery of hip joint function between the two groups at the last follow-up (P > 0.05). CONCLUSION: Both THA and PFNA internal fixation yield favorable outcomes in treating IFF with no significant difference in complications. The difference lies in the shorter operative time and lesser trauma inflicted by PFNA internal fixation, despite it involving prolonged radiation exposure and bed rest. Conversely, THA requires longer operative time and causes greater trauma but results in shorter postoperative recovery periods, allowing earlier ambulation.

The clinical outcome comparison between trans-syndesmotic fixation and anatomic deltoid ligament repair in unstable ankle fractures with medial clear space widening: A systematic review and meta-analysis.

BACKGROUND: Due to the variability in evidence supporting either trans-syndesmosis fixation or deltoid ligament repair in unstable ankle fractures with medical clear space (MCS) widening makes it unclear which surgical technique leads to the best patient outcomes. The goal of our systematic review and meta-analysis was to compare clinical outcomes of trans-syndesmotic fixation versus anatomic deltoid ligament repair in the management of unstable ankle fractures with MCS widening. METHODS: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were utilized in this study. A comprehensive and systematic search was conducted using the PubMed, Embase, Web of Science and Cochrane Library databases. Outcomes investigated in this review included the rates of syndesmotic malreduction, removal of hardware, postoperative complications including wound issues, and functional/pain scores. RESULTS: A total of five level-3 studies were selected in this review, with 280 unstable ankle fractures with MCS widening: 165 for the trans-syndesmotic fixation group and 115 for the anatomic deltoid ligament repair group. Three out of five studies evaluated syndesmotic malreduction using CT. Compared to the trans-syndesmosis fixation group, the deltoid repair group showed significant lower rates of syndesmotic malreduction rates and removal of hardware: 6.5 % (4/61) Vs. 27 % (16/59) (RR=0.26, 95 % CI=[0.10, 0.68]), and 2.6 % (3/115) Vs.54.5 % (90/165) (RR=0.06, CI=[0.02, 0.14]), respectively. No significant differences were found between the two groups in postoperative wound complications, reoperations, and functional scores including AOFAS and VAS pain score. CONCLUSIONS: Based on our findings, anatomic deltoid ligament repair was associated with a lower rate of syndesmotic malreduction and the need for hardware removal while there was no significant difference in terms of postoperative wound complications, reoperation, AOFAS score, or VAS pain score. These results should be interpreted with caution due to limitations related to heterogeneity among the studies. Further high-level RCTs with larger sample sizes are necessary to establish a robust consensus.

Development of the first Iranian clinical practice guidelines for the diagnosis, treatment, and secondary prevention of acute coronary syndrome.

Background: This article introduces the first national guidelines for the management including diagnosis, treatment, and secondary prevention of acute coronary syndrome (ACS) in Iran. Materials and Methods: The members of the guideline development group (GDG) were specialists and experts in fields related to ACS and were affiliated with universities of medical sciences or scientific associations in the country. They carefully examined the evidence and clinical concerns related to ACS management and formulated 13 clinical questions that were sent to systematic review group who developed related evidence using Grade method. Finally the GDG developed the recommendations and suggestions of the guideline. Results: The first three questions in the guideline focus on providing recommendations for handling a patient who experience chest pain at home, in a health house or center, during ambulance transportation, and upon arrival at the emergency department (ED) as well as the initial diagnostic measures in the ED. Subsequently, the recommendations related to the criteria for categorizing patients into low, intermediate and high-risk groups are presented. The guideline addressed primary treatment measures for ACS patients in hospitals with and without code 247 or having primary percutaneous coronary intervention (PCI) facilities, and the appropriate timing for PCI based on the risk assessment. In addition, the most efficacious antiplatelet medications for ACS patients in the ED as well as its optimal duration of treatment are presented. The guideline details the recommendations for therapeutic interventions in patients with ACS and acute heart failure, cardiogenic shock, myocardial infarction with nonobstructive coronary arteries (MINOCA), multivessel occlusion, as well as the indication for prescribing a combined use of anticoagulants and antiplatelet during hospitalization and upon discharge. Regarding secondary prevention, while emphasizing the referral of these patients to rehabilitation centers, other interventions that include pharmaceutical and nonpharmacological ones are addressed, In addition, necessary recommendations for enhancing lifestyle and posthospital discharge pharmaceutical treatments, including their duration, are provided. There are specific recommendations and suggestions for subgroups, such as patients aged over 75 years and individuals with heart failure, diabetes, and chronic kidney disease. Conclusion: Developing guidelines for ACS diagnosis, treatment and secondary prevention according to the local context in Iran can improve the adherence of our health care providers, patients health, and policy makers plans.

Acute Hyperglycemia and Its Impact on Mortality of Acute Coronary Syndrome Patients: A Systematic Review.

Acute hyperglycemia or stress hyperglycemia is a frequent finding in patients with acute coronary syndrome (ACS). Several studies have demonstrated the association between acute hyperglycemia with short- and long-term mortality in ACS patients. But the evidence is not concrete. We gathered 1056 articles from three databases, i.e., PubMed, Google Scholar, and Science Direct using different search strategies and filters. We then removed duplicates and 919 articles were screened with title abstract and full text. After a full-text screening of 169 articles, we removed 116 articles. We then applied eligibility criteria and did a quality assessment of articles and finally, we included 21 articles in our study. The 21 articles spanned years 2014 to 2024. Of them, 16 articles were observational studies, two were systematic reviews and meta-analyses, and three were review articles. Six articles used stress hyperglycemia ratio (SHR) alone, seven articles used admission blood glucose (ABG) alone, two used fasting plasma glucose (FPG) alone and one used SHR, ABG, and FPG together as a parameter to measure acute hyperglycemia. Short-term poor outcomes (in-hospital, <30 days) were studied in 12 studies, and long-term poor outcomes (>30 days-1 year, >1 year) were studied in six studies. A positive correlation between acute hyperglycemia and short- and long-term mortality was found in our 21 included studies. The three parameters which are used to quantify acute or stress hyperglycemia in our study, i.e., SHR, ABG, and FPG predict both short- and long-term mortality in ACS patients. Further study is needed to determine the accurate cutoff level of hyperglycemia to be called acute hyperglycemia in diabetics. We tried to review the recent literature on this topic to deepen our understanding of this topic and to provide a base for future research.

The experiences of autistic adults who were previously diagnosed with borderline or emotionally unstable personality disorder: A phenomenological study.

LAY ABSTRACT: Autistic people face many barriers to receiving an autism diagnosis. Often, they may be misdiagnosed with borderline personality disorder instead. For our study, we interviewed 10 autistic adults who had previously been diagnosed with borderline personality disorder. This helped us to better understand their experiences. They explained how borderline personality disorder is quite stigmatised and may suggest that people are to blame for their differences in behaviour. They found the treatments they had to try for borderline personality disorder to be harmful. For example, these treatments promoted 'masking'. Previous research showed that masking can be harmful for autistic people, linking it to risk of suicide. This diagnosis also led to healthcare professionals neglecting them and discounting their beliefs. Once they were diagnosed with borderline personality disorder, it was hard to access an autism assessment. When they did receive their autism diagnoses, this was much more positive. This diagnosis was validating. It also improved their mental health, as they were no longer expected to mask - their differences were now accepted. They still felt that autism was stigmatised in society. However, this was very different to the stigma around borderline personality disorder. They felt autism stigma was more about their competence as people, whereas borderline personality disorder stigma was about how they were broken and might be harmful to others. This study is important because it allows their stories to be heard by researchers and healthcare professionals alike. Adding their voices helps to humanise them, promoting positive change in mental health services. More research is now needed.

First Report of Hb Youngstown in Capillary Electrophoresis and Overlapping Hb Analysis Findings with Hb Rush.

Hb Youngstown [HBB:c.305A > C] is a rare unstable hemoglobin caused by the substitution of glutamic acid with alanine at codon 101 of the Beta globin chain. It causes hemolytic anemia in the heterozygous state. This is a case of a six-year-old Chinese-Javanese girl with heterozygous Hb Youngstown and clinical features of chronic hemolysis and iron overload. Hb Youngstown appears at the S window near to 4.6 minutes on high-performance liquid chromatography (HPLC) and can form a hybrid tetramer on alkaline gel electrophoresis seen as two distinct bands cathodal to A and close to F. For the first time, Hb Youngstown is captured with capillary electrophoresis (CE) and shown to be eluted at zone 8. Clinical presentation and Hb analysis results of this heterozygous Hb Youngstown overlap with heterozygous Hb Rush. They can only be differentiated at molecular level by Beta globin gene sequencing or intact mass spectrometry.

Bipolar Hemiarthroplasty With a Calcar Stem for the Management of a Failed Proximal Femoral Nail Anti-rotation Asia (PFNA2) in a Case of Geriatric Unstable Intertrochanteric Femur Fracture.

Intertrochanteric (IT) femur fractures in the elderly population comprise a major part of geriatric trauma and fractures. There are various modalities of surgical management, ranging from intramedullary fixation and extramedullary fixation to even replacing the hip joint. Apart from the surgeon's choice, other factors, such as geriatric age, bone quality and osteoporosis, medical comorbidities, life expectancy, pre-operative ambulatory status, muscle strength, type and pattern of fracture, and mental health of the patient, play vital roles in determining the ideal modality of management and the long-term outcome. The present case is a 75-year-old lady who had an IT fracture due to a domestic fall, managed surgically with a proximal femoral nail anti-rotation Asia (PFNA2) for an unstable fracture. She presented with blade back-out on the 11th day postoperatively. The patient was investigated thoroughly, and infection was ruled out. She was managed by the removal of the nail, followed by a cemented calcar-replacing bipolar hemiarthroplasty for an unstable comminuted IT fracture. The patient was ambulatory with a walker by the seventh postoperative day and without a walker by the sixth week, and she was self-sufficient in her activities of daily living. Every geriatric IT fracture must be evaluated thoroughly for contributing factors, such as osteoporosis and fracture pattern, to predict outcomes, and a tailor-made strategy of surgical management and stepwise physiotherapy must be provided to the patient for the best results.

Comparative efficacy of proximal femoral nail vs dynamic condylar screw in treating unstable intertrochanteric fractures.

BACKGROUND: Among the most frequent hip fractures are trochanteric fractures, which usually occur from low-energy trauma like minor falls, especially in older people with osteoporotic bones. AIM: To evaluate the treatment efficacy of dynamic condylar screws (DCS) and proximal femoral nails (PFN) for unstable intertrochanteric fractures. METHODS: To find pertinent randomized controlled trials and retrospective observational studies comparing PFN with DCS for the management of unstable femoral intertrochanteric fractures, a thorough search was carried out. For research studies published between January 1996 and April 2024, PubMed, EMBASE, Scopus, Web of Science, Cochrane Library, and Google Scholar were all searched. The complete texts of the papers were retrieved, vetted, and independently examined by two investigators. Disputes were settled by consensus, and any disagreements that persisted were arbitrated by a third author. RESULTS: This study included six articles, comprising a total of 173 patients. Compared to the DCS, the PFN had a shorter operation time [mean difference (MD): -41.7 min, 95% confidence interval (95%CI): -63.04 to -20.35, P = 0.0001], higher success rates with closed reduction techniques [risk ratio (RR): 34.05, 95%CI: 11.12-104.31, P < 0.00001], and required less intraoperative blood transfusion (MD: -1.4 units, 95%CI: -1.80 to -1.00, P < 0.00001). Additionally, the PFN showed shorter fracture union time (MD: -6.92 wk, 95%CI: -10.27 to -3.57, P < 0.0001) and a lower incidence of reoperation (RR: 0.37, 95%CI: 0.17-0.82, P = 0.01). However, there was no discernible variation regarding hospital stay, implant-related complications, and infections. CONCLUSION: Compared to DCS, PFN offers shorter operative times, reduces the blood transfusions requirements, achieves higher closed reduction success, enables faster fracture healing, and lowers reoperation incidence.

[Scoring system for unstable spinal gunshot wounds: the study protocol]. / Ball'naya takticheskaya klassifikatsiya nestabil'nykh ognestrel'nykh ranenii pozvonochnika: protokol issledovaniya.

Morphology of injuries following gunshot wounds requires specific treatment approaches. Currently, there are no similar classifications for assessing fracture stability with subsequent tactical recommendations. Taking into account diagnostic limitations (contraindications for MRI due to implantable metal fragments, limitations of functional radiography of the spine in seriously injured patients), we make decisions considering CT data. In this study, we will determine severity of vertebral damage and effect of these damages on mechanical stability of spinal motion segments. In the future, CT-based assessment of inter-expert agreement will be performed. Finally, we will propose the scoring system for classification of spinal gunshot wounds. OBJECTIVE: To present a research protocol for development of new scoring system for unstable spinal gunshot wounds based on inter-expert agreement assessment. MATERIAL AND METHODS: To create a new tactical classification, we will distinguish and analyze clinical and CT data of patients with thoracolumbar spinal gunshot wounds. The Delphi method will be used to collaborate between several surgeons. A three-stage study will result a questionnaire (for 30 clinical cases). We will develop tactical scoring system and analyze statistical data (kappa). DISCUSSION: Various classifications have been developed for closed spinal injuries. These systems describe the nature of injury and allow one to develop tactical decisions for further actions. Another mechanism of injuries following gunshot wounds does not allow the classification of closed injuries to be adequately applied in some cases. Indeed, spinal structures follow either direct passage of a wounding projectile through the spine or transferring the energy of this projectile in contrast to classical compression, distraction and rotational-translation mechanisms typical for closed trauma.

[Analysis of the unicentric registry of the Infarction Code program: retrospective cohort]. / Análisis del registro unicéntrico del programa Código Infarto: cohorte retrospectiva.

Background: Acute coronary syndrome (ACS) is the most serious manifestation of coronary heart disease. The Infarction Code (according to its initialism in Spanish, CI: Código Infarto) program aims to improve the care of these patients. Objective: To describe the clinical presentation and outcomes of CI program in a coronary care unit (CCU). Material and methods: A database of a CCU with 5 years of consecutive records was analyzed. Patients diagnosed with ACS were included. The groups with acute myocardial infarction with and without ST-segment elevation were compared using Student's t, Mann-Whitney U and chi-squared tests. We calculated the relative risk (RR) and 95% confidence intervals (95% CI) of cardiovascular risk factors for mortality. Results: A total of 4678 subjects were analyzed, 78.7% men, mean age 63 years (± 10.7). 80.76% presented acute myocardial infarction with positive ST-segment elevation and fibrinolytic was granted in 60.8% of cases. Percutaneous coronary intervention was performed in 81.4% of patients, which was successful in 82.5% of events. Patients classified as CI presented mortality of 6.8% vs. 11.7%, p = 0.001. Invasive mechanical ventilation had an RR of 26.58 (95% CI: 20.61-34.3) and circulatory shock an RR of 20.86 (95% CI: 16.16-26.93). Conclusions: The CI program decreased mortality by 4.9%. Early fibrinolysis and successful coronary angiography are protective factors for mortality within CCU.

Resultados: se analizaron 4678 sujetos, 78.7% hombres, con media de edad de 63 años (± 10.7). El 80.76% presentó infarto agudo de miocardio con desnivel positivo del segmento ST y se otorgó fibrinolítico en el 60.8% de los casos. Se realizó intervencionismo coronario percutáneo en el 81.4% de los pacientes, el cual fue exitoso en el 82.5% de los eventos. Los pacientes catalogados como CI presentaron mortalidad del 6.8% frente a 11.7%, p = 0.001. La ventilación mecánica invasiva tuvo una RR de 26.58 (IC 95%: 20.61-34.3) y el choque circulatorio una RR de 20.86 (IC 95%: 16.16-26.93). Conclusiones: el programa CI disminuyó 4.9% la mortalidad. La fibrinólisis temprana y la angiografía coronaria exitosa son factores protectores para mortalidad dentro de la UCC.

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.

Correlation between the TyG-BMI index and carotid plaque characteristics in middle-aged and elderly patients with acute myocardial infarction.

OBJECTIVE: The aim of this study is to investigate the correlation between the triglyceride-glucose-body mass index (TyG-BMI) and the characteristics of various carotid plaques in middle-aged and elderly patients with acute myocardial infarction (AMI). METHODS: A retrospective study was conducted on 380 patients with AMI hospitalized in the Cardiology Department of Kaifeng Central Hospital. Based on carotid ultrasound results, patients were divided into the following two groups: the stable plaque group and the unstable plaque group. Additionally, a control group comprising 380 healthy individuals visiting the hospital's physical examination center during the same timeframe was established. Fasting venous blood samples were collected from all participants to measure blood glucose and triglyceride. The baseline TyG-BMI index was calculated using the formula Ln [fasting triglyceride (mg/dL)×fasting blood glucose (mg/dL)/2]×BMI. The correlation between different plaque groups and the TyG-BMI index was analyzed. RESULTS: The TyG-BMI index was significantly higher in the unstable plaque group compared to the stable plaque group, with values of 252.81±29.99 and 201.92±28.72, respectively (P = 0.034). Spearman's correlation analysis showed a positive correlation between the instability of carotid plaques and the TyG-BMI index in patients with AMI (r = 0.521, P = 0.003). Logistic regression analysis indicated that the TyG-BMI index was an important risk factor for unstable carotid plaques in patients with AMI (OR = 2.691, 95% CI: 1.169-4.123). CONCLUSION: The findings of this study suggest that an elevated TyG-BMI index significantly increases the risk of unstable carotid plaques in patients with AMI, making it an important risk factor for carotid plaque instability.

Lateral Ankle Ligament Repair Is Not Only for Young Patients: Trends in Incidence and Demographics.

The purpose of this study was to examine the changes in annual incidence and patient population undergoing lateral ankle ligament repair (LALR) for the surgical treatment of chronic ankle instability. The IBM Watson Health MarketScan Database was queried for patients who underwent LALR from January 2009 to December 2019 based on CPT code 27698. Volume and incidence per 100 000 population were determined for annual sums, gender, age, and geographical regions based on population estimates from the United States Census Bureau. Future annual volumes were statistically projected with linear regression modeling to the year 2032. Overall, 160 457 LALR procedures were identified in the database from 2009 to 2019. Annual incidence increased 76.6% from 3.46 to 6.11 cases per 100 000 population, while estimates of annual volumes are projected to increase 61.5% from 19 829 to 32 033 procedures to the year 2032. Interestingly, the greatest increase in incidence was observed among patients above 70 years old, which might suggest older patients are staying active longer and desiring elective procedures to maintain their activity levels. As the incidence of LALR increases in older patients, more research will be needed to understand the unique surgical considerations and risk factors impacting patient-reported outcomes.Level of Evidence: Level IV.

Efficacy and outcomes of rescue screws in unstable pelvic ring injuries - A retrospective matched cohort study.

PURPOSE: The emergency treatment of unstable pelvic ring injuries is still a challenge and requires surgical and anesthesiological resuscitation. Emergency fixation of the unstable pelvic ring with percutaneous sacroiliac (SI) screws, also known as "Rescue Screws", is an established treatment method. The aim of our study was to compare the outcome and complication rates of "Rescue Screws" with elective SI-screw fixations. METHODS: A 1:1 ratio nearest-neighbor matched, retrospective cohort study of trauma patients with acute pelvic ring injuries at a level one trauma center was performed. Patients ≥ 15 years, treated with SI-screw fixation were included. EXCLUSION CRITERIA: pathologic fractures, missing consent and navigated procedures. The primary outcome parameters was defined as SI-screw revision operations. Patients were stratified according to treatment strategy (RS: Rescue Screws; EL: elective SI-screws). RESULTS: From 392 patients identified between 11/2014 and 08/2021, 186 met the inclusion criteria with 41 in the RS Group and 145 in the EL group. After matching, 41 patients were included in each group with similar baseline characteristics except persistent hemodynamic shock (RS: n = 22 (53.37%) vs. EL: n = 1 (4.3%), p < 0.001). Surgical characteristics were comparable in terms of instrumentation levels and insertion-sites. No significant differences were observed in the outcome parameters (revisions, reoperations, implant-associated complications, LOS and mortality) between both groups. CONCLUSION: Treatment of unstable pelvic ring fractures with Rescue Screws appears as a feasible treatment option for emergency stabilization. Rescue Screws are not associated with elevated revision rates and increased complications rates. This minimally invasive technique enables safe emergency stabilization of the posterior pelvic ring. Prospective or randomized clinical trials are required to directly compare Rescue Screws with other competing emergency stabilization techniques.

[Proximal femoral nail antirotation combined with locking plate in the treatment of femoral intertrochanteric fractures with lateral wall fractures].

OBJECTIVE: To investigate the effect of locking plate internal fixation for the treatment of proximal lateral femoral wall fracture. METHODS: From January 2021 to June 2022, 31 patients with intertrochanteric fractures and lateral wall fractures were treated. Among them, 15 patients were treated with proximal femoral nail antirotation (PFNA) fixation including 3 males and 12 females with an average age of (75.87±7.46) years old;the other 16 patients were treated with 3.5 mm pre-curved screw locking plate fixtion for lateral wall fracture including 4 males and 12 females with an average age of (76.15±9.47) years old. After surgery, the surgical index, tip-apical distance(TAD), postoperative standing weight-bearing time, and fracture reduction were compared between two groups. Postoperative hip function was evaluated according to Harris hip score. RESULTS: All patients were followed up for an average of (12±5) months ranging from 7 to 17 months. The immediate postoperative neck angle ranged from 111° to 132°(119.3±8.3)°. Fracture reduction results were excellent in 11 cases, fair in 2, worse in 1 in PFNA group;excellent in 12, fair in 3, worse in 1 in PFNA+locking plate group. One case of the PFNA group had a spiral blade cut out through the femoral head. There were significant differences in the time of operation, the amount of blood loss during the operation, the length of incision between two groups(P<0.05). There was no significant difference in TAD and postoperative standing weight-bearing time between two groups(P>0.05). There were significant differences in Harris scores at 6 months after surgery between two groups(P<0.05). CONCLUSION: The application of PFNA-assisted locking plate in the treatment of femoral intertrochanteric fractures with lateral wall fractures is effective, and can restore the integrity of lateral wall, improve the stability of PFNA internal fixation, and reduce postoperative complications.

Treatment of the Distal Forearm Fracture by Volar Dual Window Approach.

BACKGROUND: Distal forearm fractures were defined as distal radius fractures with concomitant distal ulna fractures, except ulna styloid fractures. Distal forearm fractures are common among geriatric populations, particularly those with osteoporosis. Conventionally, distal forearm fractures are reduced by a double incision approach; however, malreduction and instability of the distal radioulnar joint were not uncommon. We introduced a modified volar dual window approach to treat the distal forearm fracture and evaluate the functional outcomes and complications. METHODS: From January 2020 to June 2023, 13 patients with distal forearm fractures underwent open reduction by the modified dual window approach with locking plate fixation. After surgery, splints were applied for two weeks, and the patients underwent postoperative hand therapy for three months. The mean Quick Disabilities of the Arm, Shoulder, and Hand scores, range of motions, grip strength, postoperative radiographic parameters, and complications data were collected. RESULTS: The mean follow-up period was 12.1 months, and the mean age was 52.3 years. Average wrist flexion was 67°, extension 69°, pronation 81°, and supination 79°. Grip strength was 28.3 ± 11.5 kg, which was 88% of the uninjured opposite side. The Visual Analog Scale score during activities was recorded as 0.5 ± 0.9. The mean Quick Disabilities of the Arm, Shoulder, and Hand score was 14 ± 11.5. The postoperative radiographic parameters were as follows: radial height: 10.8 ± 1.7 mm, radial inclination: 22.6 ± 3.7°, volar tilting: 4.0 ± 3.9°, and ulnar variance: -0.4 ± 1.4 mm. All the patients achieved bone union at the final follow-up. Two patients underwent ulnar implant removal due to irritation symptoms. Neither infection, nor neurovascular injury, nor malreduction developed in these patients. CONCLUSIONS: The modified volar dual window approach can achieve good wrist function and distal forearm fracture reduction without increasing neurovascular or wound healing complications. This method is an alternative approach for distal forearm fracture, especially in comminuted distal ulna fracture or distal radioulnar joint incongruity.

Hemoglobinopathy as a Rare Differential Disease for Low Oxygen Saturation by Pulse Oximetry: A Case Report and Literature Review.

Pulse oximetry is used to screen for respiratory failure in dyspnea patients. However, pulse oximetry can yield false-positive results in certain situations. Unstable hemoglobinopathy is a disease in which mutations in the globin-encoding gene result in abnormal globin chain production, causing low percutaneous oxygen saturation (SpO2) levels due to changes in hemoglobin absorbance and oxygen affinity. We identified a new family lineage of Hb Hirosaki in an adult patient with chronic obstructive pulmonary disease, dyspnea, and low SpO2. According to our literature review, only a few cases of unstable hemoglobinopathy have been reported in adults. Most patients with unstable hemoglobinopathy are asymptomatic, and those with dyspnea often have respiratory diseases or severe anemia. To differentiate unstable hemoglobinopathy, an appropriate assessment of the discrepancy between SpO2 values and arterial blood gas analysis results is important.

Unveiling the Link: Hypocalcemia-Induced Unstable Sustained Ventricular Tachycardia in Nonischemic Cardiomyopathy.

A 63-year-old female presented to a freestanding emergency room with dizziness, palpitations, and hypotension, The patient was found to have an irregular wide complex tachycardia, consistent with ventricular tachycardia, hypomagnesemia and severe hypocalcemia. The tachycardia was refractory to treatment with IV amiodarone and magnesium, and only resolved with correction of the serum calcium. Review of the medical record revealed an echocardiogram 19 years earlier reporting left ventricular dysfunction. The patient was unaware of this diagnosis and was not taking medical therapy. Echocardiogram revealed no significant change in left ventricular function, and coronary angiography showed no significant coronary artery disease. The patient's nonischemic cardiomyopathy may have been a predisposing factor for the arrhythmia presentation. We explore a hospital admission involving the rare association of hypocalcemia and monomorphic ventricular tachycardia, which is not well documented in the literature.

The effect of anterior support screw (AS2) in unstable femoral trochanteric fractures: A multicenter randomized controlled trial.

OBJECTIVES: This study was conducted to verify the effectiveness of Anterior Support Screw (AS2) for unstable femoral trochanteric fractures. DESIGN: A multicenter, prospective, randomized controlled trial SETTING: This study was conducted across 15 academic medical centers in Japan PATIENTS/PARTICIPANTS: We enrolled 240 cases of femoral trochanteric fractures with posterior crushing and intramedullary displacement of proximal bone fragments across 15 institutions in Japan. INTERVENTION: All patients were subjected to a reduction in which the anterior cortex was brought into contact. The patients were randomly assigned to the anterior support screw group (AS2 group) and the non-screw group (control group). MAIN OUTCOME MEASUREMENTS: Two computed-tomography (CT) scans were taken immediately after surgery and early postoperative period (day 14-21) to investigate the reduction loss rate of the anterior cortex and sliding distances in the early postoperative period. RESULTS: The reduction loss rate was 4.5 % in the AS2 group and 16.8 % in the control group, indicating a significantly lower reduction loss rate in the AS2 group (p = 0.003). The average sliding distance was 1.8 mm in the AS2 group and 2.8 mm in the control group, indicating a significantly shorter sliding distance in the AS2 group (p < 0.0001). CONCLUSION: Adding a screw in front of the intramedullary nail significantly reduces reduction loss, and maintains anterior bony contact. This study also showed that these screws suppress the sliding distance during the postoperative period. LEVEL OF EVIDENCE: Therapeutic Level I.
