Evaluation of Posterior Ligamentous Complex Injury in Thoracolumbar Burst Fractures: Correlation Analysis of CT and MRI Findings.

The goal of this study is to perform correlation analysis of Computed tomography (CT) and magnetic resonance imaging (MRI) results in posterior ligament complex (PLC) injury and define the morphological traits of thoracolumbar (TL) burst fractures connected to PLC injury. Forty patients with surgically repaired TL burst fractures between January 2013 and December 2020 were retrospectively analyzed. The patients were split into two groups for comparison based on MRI (Group P: patients with a confirmed or suspected PLC injury; Group N: patients with PLC injury denied). The radiographic morphological examination based on CT scans and clinical evaluation was performed and compared between two groups. The thoracolumbar injury classification and severity score (TLICS), the load sharing classification (LSC) scores, and the number of patients with neurological impairments were considerably greater in Group P. Loss of height of the fracture (loss height), local kyphosis of the fracture (local kyphosis), and supraspinous distance were significantly higher in Group P and significantly associated with PLC injuries indicating severe vertebral body destruction and traumatic kyphosis in multivariate logistic analysis [odds ratio: 1.90, 1.06, and 1.13, respectively]. Cutoff value for local kyphosis obtained from the receiver operating characteristic curve was 18.8. If local kyphosis is greater than 18.8 degrees on CT scans, we should take into account the probability of the highly damaged burst fracture associated with PLC injury. In this situation, we should carefully assess MRI to identify the spinal cord injury or spinal cord compression in addition to PLC injury because these instances likely present with neurological abnormalities.

Post-traumatic stress disorder among individuals with traumatic spinal cord injury in Nepal: a cross-sectional study.

Cross-sectional study OBJECTIVES: To identify the prevalence of posttraumatic stress disorder (PTSD) among the individuals with traumatic spinal cord injury (TSCI) and to examine the relationships between demographic and clinical characteristics, and PTSD. Spinal Injury Rehabilitation Center (SIRC) and Dhulikhel Hospital, Kathmandu University Hospital (DH, KUH), Kavrepalanchowk, Nepal. Individuals above 18 years of age with TSCI of at least one month from trauma and admitted to SIRC and DH, KUH from June 2019 to May 2021 were included. The specific stress version of the PostTraumatic Stress Disorder Checklist (PCL), was utilized. To classify the neurological status of TSCI individuals, International Standard for Neurological Classification of Spinal Cord Injury (ISNCSCI) was used. Hierarchical multiple regression analysis between independent variables and normalized PCL score was done to evaluate the predictors of PTSD. Among 163 patients, the overall prevalence of PTSD was 27%, and the mean PCL score was 36 ± 13.9. Factors predictive of PTSD included gender, family type, ethnicity, and literacy rate. No significant association was found between the clinical characteristics and PTSD. PTSD appears to be considerably prevalent among individuals with TSCI in Nepal. Females, individuals from nuclear families, individuals with lower literacy, and individuals from lower caste are significantly vulnerable to developing PTSD. However, clinical characteristics do not appear to be influential in the development of PTSD.

Clinical characteristics of acute kidney injury in patients with glyphosate surfactant herbicide poisoning.

In this study, we investigated the clinical characteristics of acute kidney injury (AKI) in patients with glyphosate surfactant herbicide (GSH) poisoning. This study was performed between 2008 and 2021 and included 184 patients categorized into the AKI (n = 82) and nonAKI (n = 102) groups. The incidence, clinical characteristics, and severity of AKI were compared between the groups based on the Risk of renal dysfunction, Injury to the kidney, Failure or Loss of kidney function, and End-stage kidney disease (RIFLE) classification. The incidence of AKI was 44.5%, of which 25.0%, 6.5%, and 13.0% of patients were classified into the Risk, Injury, and Failure categories, respectively. Patients in the AKI group were older (63.3 ± 16.2 years vs. 57.4 ± 17.5 years, p = 0.02) than those in the non-AKI group. The length of hospitalization was longer (10.7 ± 12.1 days vs. 6.5 ± 8.1 days, p = 0.004) and hypotensive episodes occurred more frequently in the AKI group (45.1% vs. 8.8%, p < 0.001). Electrocardiographic (ECG) abnormalities on admission were more frequently observed in the AKI group than in the non-AKI group (80.5% vs. 47.1%, p < 0.001). Patients in the AKI group had poorer renal function (estimated glomerular filtration rate at the time of admission, 62.2 ± 22.9 mL/min/1.73 m2 vs. 88.9 ± 26.1 mL/min/1.73 m2 , p < 0.001) on admission. The mortality rate was higher in the AKI group than in the non-AKI group (18.3% vs. 1.0%, p < 0.001). Multiple logistic regression analysis showed that hypotension and ECG abnormalities upon admission were significant predictors of AKI in patients with GSH poisoning. The presence of hypotension on admission may be a useful predictor of AKI in patients with GSH intoxication.

After SCI 90% of men with SCI will need a method of assisted ejaculation to achieve biological fatherhood. Penile vibratory stimulation (PVS) was popularized in 1994 after the production of the first vibrator specifically designed for semen retrieval in men with SCI. The success of this device was based on a calculated amplitude of 2.5 mm which was proven to be optimal for successfully producing an ejaculate. PVS is safe, reliable, can be performed by the male partner at home after an initial evaluation by a health care provider and yields the best sperm quality.A newly designed vibrator was produced in 2019 and was tested by a group of international experts for safety and efficacy. The study concluded the device was safe and effective in inducing ejaculation in men suffering from anejaculation after SCI. METHODS: Initial encounter: standard history, physical exam and level of injury determination using the International Standards for Neurological Classification of Spinal Cord Injury were performed. In addition, assessment of Hip Flexor Reflex and Bulbocavernosus Reflex was performed. Procedure: Patients with a level of injury at or rostral to T6 were pretreated with 10-40 mg of sublingual nifedipine to mange autonomic dysreflexia. The patient lied supine on the exam table and the vibrator was applied to the dorsum or frenulum of the glans penis. Stimulation was delivered in 2-minute increments to a maximum of 10 minutes per visit. Stimulation using 2 vibrators (Sandwich technique) or with abdominal electrical stimulation can be performed in select patients. Semen: Ejaculated semen was collected in a sterile cup and a semen analysis was performed after liquefaction. Bladder preparation using sperm wash medium was performed in patients suspected of having retrograde ejaculation. RESULTS: PVS was successful in 86% of men whose level of injury was T10 or rostral. A total of 3,698 PVS procedures were successfully performed by our group. The total motile sperm count in antegrade ejaculates produced by PVS was >5 million (lower limit considered for IUI) in 71% of ejaculates. CONCLUSIONS: PVS is a safe and effective method to manage anejaculation in men with SCI. Sperm can be obtained non surgically from most men with SCI. Sufficient sperm are available for simple insemination procedures. PVS should be considered as the method of choice for semen retrieval in this patient population.

188 American Spinal Injury Association (ASIA) Impairment Scale (AIS) Conversion Underestimates Neurological Recovery Following Traumatic Spinal Cord Injury

INTRODUCTION: The predominant tool used in the evaluation of neurological outcomes following spinal cord injury (SCI) is the American Spinal Injury Association (ASIA) Impairment Scale (AIS), calculated within the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI). However, there are significant clinical and functional differences within AIS grades A-E that can be better captured by ISNCSCI 0-100 full motor scores. METHODS: 55 patients with acute traumatic SCI who underwent surgery were retrospectively analyzed as part of a prospective cohort study, Transforming Research and Clinical Knowledge in SCI (TRACK-SCI). Clinical, radiographical and treatment parameters were collected, including AIS grades and full motor scores on presentation and discharge, Brain and Spinal Injury Center (BASIC) scores. Multivariable analysis was utilized to evaluate predictors of neurological recovery utilizing AIS grade and motor scores as endpoints. RESULTS: Improvement of at least 1 AIS grade from presentation was noted in 27% of patients (mean improvement of 0.3 AIS grades, p < 0.001) upon discharge. Improvement of total motor scores was noted in 67% with a mean recovery of 8.4 points. The discordance between rate of AIS grade conversion and motor score recovery was greatest in patients with initial AIS grade D (16% vs 72%, respectively). Total motor score improvement was greatest for patients with initial AIS grade C, with a mean improvement of 20 points. Utilizing multivariate analysis, BASIC score and initial total motor score were significant predictors of motor score recovery. However, no variables were prognostic when utilizing AIS conversion as the endpoint. CONCLUSIONS: AIS conversion underestimates true degree of functional improvement following SCI. Changes in full motor score is a more robust outcome metric in the evaluation of factors prognostic of neurological recovery following injury.

Imaging in Sports Medicine

Muscular, soft tissue, and bony injuries are common among athletes. Different imaging modalities can be used to assess these patients depending on the type of injury and the expert opinion. Multiple imaging modalities are used to diagnose, investigate, and decide an appropriate medical or surgical treatment. Among the modalities that are used, magnetic resonance imaging and ultrasound (US) are commonly used to illustrate soft tissue injuries. Radiographs are cheap and are commonly used. The British Athletic Muscle Injury Classification is a grading system used for muscle injuries and can be used to predict the time it takes for a player to return fully. Tendons and ligaments are graded from 1 to 3, and the Fredericson grading system is used to classify bony injuries. Many of the common sports injuries are graded using these grading systems. Good communication and collaboration among sports physicians, surgeons, and radiologists are essential to adequate injury management in athletes. Appropriate choice of imaging modalities, classification systems, and a knowledge of common sports injuries can facilitate this.

Transposition of functioning muscles in complex treatment of adult patients with injuries of the bracheric plexus (literature review)

Introduction. Injuries to the brachial plexus are one of the most severe types of injuries to the nerves of the upper limb, and variants with the separation of the roots from the spinal cord represent a very difficult category of injuries to treat. Among patients who have received such injuries, there is a very high incidence of disability, since it is possible to achieve only partial restoration of the function of the upper limb. Recently, the method of transposition of functioning muscles has been growing in popularity due to its reliability and relatively short recovery time of function.The purpose of the work is to analyze the literature data on the possibility of using the method of transposition of functioning muscles in the complex treatment of victims with brachial plexus injuries.The authors have searched PubMed and RSCI databases over the past 25 years for keywords: peripheral nerve damage, tendon transposition, transposition of functioning muscles, nerve injury, brachial plexus injury, spinal cord root avulsion. In the selected 23 most relevant papers, the muscles used for transposition, indications and timing of operations, results and complications were analyzed, compared with other methods of surgical treatment of brachial plexus injuries. The analysis of studies has shown that the transposition of functioning muscles allows in most cases to restore the target movement to the useful level of M3–M4 on the MRC scale, is a more reliable method and allows achieving better results, especially in patients with severe complete injuries of the brachial plexus. An important disadvantage of free hip thin muscle transplantation operations is the risk of microanastomosis thrombosis, which requires detailed preoperative planning and good microsurgical technique of the operating team.Conclusion. Free transplantation of 2 functioning muscles is currently the method of choice for restoring upper limb movements in patients with complete brachial plexus injuries.

Physiotherapy management on sprain medial collateral ligament in sports injury: a literature study

Background: The risk of sports activities is injuries. There are two types of injury classification often experienced by athletes: acute trauma and overuse. The part of the body in sports that are quite common injuries due to body contact is the knee. Medial collateral ligament (MCL) injuries were one of the most common knee injuries in sports. The role of physiotherapy in MCL injury conditions is to improve knee conditions in athletes, prevent re-current of injuries, help heal the athlete's condition after MCL injury with existing modalities and help restore the condition, which aims to make the athlete able to return to play in their sport.
 Methods: This study used library research which takes online and offline data sources to refer to books and scientific articles related to examination and physiotherapy intervention in the condition of MCL sprain injury.
 Results: Physiotherapists must carefully examine every symptom that appears by examining the basic function of motion, palpation, specific test with a valgus stress test, and functional evaluation in conditions of MCL sprain injury.
 Conclusions: In athletes, physiotherapy interventions must be graded, like reducing acute injury symptoms, exercising using tools, and reducing pain in the first phase; the second phase with increasing functional ability, flexibility, range of motion, and returning muscle strength; in the third phase, muscle strength must increase as before, returning agility, balance, and flexibility; furthermore, in the fourth phase, the athlete is prepared to return to sport with strength training, flexibility, agility, and sport-specific exercise.

Automated detection and classification of acute vertebral body fractures using a convolutional neural network on computed tomography.

Acute vertebral fracture is usually caused by low-energy injury with osteoporosis and high-energy trauma. The AOSpine thoracolumbar spine injury classification system (AO classification) plays an important role in the diagnosis and treatment of the disease. The diagnosis and description of vertebral fractures according to the classification scheme requires a great deal of time and energy for radiologists. To design and validate a multistage deep learning system (multistage AO system) for the automatic detection, localization and classification of acute thoracolumbar vertebral body fractures according to AO classification on computed tomography. The CT images of 1,217 patients who came to our hospital from January 2015 to December 2019 were collected retrospectively. The fractures were marked and classified by 2 junior radiology residents according to the type A standard in the AO classification. Marked fracture sites included the upper endplate, lower endplate and posterior wall. When there were inconsistent opinions on classification labels, the final result was determined by a director radiologist. We integrated different networks into different stages of the overall framework. U-net and a graph convolutional neural network (U-GCN) are used to realize the location and classification of the thoracolumbar spine. Next, a classification network is used to detect whether the thoracolumbar spine has a fracture. In the third stage, we detect fractures in different parts of the thoracolumbar spine by using a multibranch output network and finally obtain the AO types. The mean age of the patients was 61.87 years with a standard deviation of 17.04 years, consisting of 760 female patients and 457 male patients. On vertebrae level, sensitivity for fracture detection was 95.23% in test dataset, with an accuracy of 97.93% and a specificity of 98.35%. For the classification of vertebral body fractures, the balanced accuracy was 79.56%, with an AUC of 0.904 for type A1, 0.945 for type A2, 0.878 for type A3 and 0.942 for type A4. The multistage AO system can automatically detect and classify acute vertebral body fractures in the thoracolumbar spine on CT images according to AO classification with high accuracy.

Comparison of curative effect between percutaneous compression plate and cannulated compression screw in the treatment of displaced femoral neck fractures in young and middle-aged patients

To compare the efficacy of percutaneous compression plate and cannulated compression screw in the treatment of displaced femoral neck fractures in young and middle-aged patients. From January 2015 to July 2020, 68 young and middle-aged patients with displaced femoral neck fracture were retrospectively analyzed. Among them, 31 cases were fixed by percutaneous compression plate (PCCP), and 37 cases were fixed by cannulated compression screw (CCS). General data such as gender, age, cause of injury, comorbidities, fracture classification and cause of injury of two groups were collected. The operation time, intraoperative blood loss, hospital stay, full weight bearing time, fracture healing time, visual analogue scale(VAS), Harris hip score and complications were compared between two groups. Patients in both groups were followed up for more than 2 years. There were no significant differences in operation time, intraoperative blood loss, fracture reduction quality, hospital stay and VAS between two groups. The fracture healing time in PCCP group was significantly shorter than that in CCS group (t=-4.404, P=0.000). The complete weight bearing time of PCCP group was significantly shorter than that of CCS group (t=-9.011, P=0.000). Harris score of hip joint in PCCP group was better than that in CCS group 2 years after operation (P=0.002). Complications occurred in 3 cases (9.68%) in PCCP group, while 11 cases (29.72%) in CCS group, with a statistically significant difference (P=0.042). Both PCCP and CCS can be used for the treatment of displaced femoral neck fractures in young and middle-aged people. Compared with CCS, PCCP fixation can achieve shorter fracture healing time and create conditions for early full weight bearing. PCCP results in higher hip score and lower complications.

Effects of mental fatigue on biomechanical characteristics of lower extremities in patients with functional ankle instability during unanticipated side-step cutting.

Background: Functional ankle instability (FAI) is the primary classification of ankle injuries. Competitive activities have complicated movements that can result in ankle re-injury among patients with FAI. Unanticipated movement state (MS) and mental fatigue (MF) could also happen in these activities, which may further increase their joint injury risk. Objective: This study aimed to clarify the biomechanical characteristics difference of the lower extremity (LE) between the injured side and the uninjured side among patients with FAI when they perform unanticipated side-step cutting after MF. Methods: Fifteen males with unilateral FAI participated in this study (age: 20.7 ± 1.3years, height: 173.6 ± 4.4cm, weight: 70.1 ± 5.0kg). They used the injured side and the uninjured side of LE to complete anticipated and unanticipated side-step cutting before and after MF. The kinematic and kinetics data were evaluated using three-way ANOVA with repeated measures. Results: During patients with FAI performed anticipated side-step cutting, the ankle stiffness of both sides showed no significant change after MF; During they performed unanticipated side-step cutting, their injured side presented significantly lower ankle stiffness after MF, while the uninjured side did not have such change. In addition, after MF, the injured side exhibited increased ankle inversion, knee valgus and LR, but the uninjured side did without these changes. Conclusion: Influenced by MF, when patients with FAI use their injured side of LE to perform side-step cutting, this side LE has a higher risk of musculoskeletal injuries such as lateral ankle sprains and anterior cruciate ligament injury. The ankle stiffness of the injured side will be further reduced when patients with FAI perform unanticipated side-step cutting, which increases ankle instability and the risk of re-injury.

The Impact of Vertebroplasty on Sagittal Parameters in Traumatic Thoracic Vertebral Fractures

Objective: It is well-established that vertebroplasty has effects on sagittal parameters due to various pathologies of the spine. Our objective in the study was to reveal the impact of vertebroplasty that was applied to compression fractures due to trauma on sagittal parameters. Material and Method: Twenty patients were included in the study. Scoliosis radiographs were shot preoperatively and at first month during the postoperative period. Spinopelvic parameters of each patient including pelvic incidence (PI), sacral slope (SS), pelvic tilt (PT), lumbar lordosis (LL), thoracic kyphosis (TK), thoracolumbar kyphosis (TLK), cervical lordosis (CL), and sagittal vertical axis (SVA) were assessed. Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) assessments of the patients were performed as well. Results: Spinopelvic parameter values of the patients were assessed statistically through the analysis of the Paired sample T test before surgery and in the first month during the postoperative period. It was determined that the changes in the PT, SS and LL values of the patients between preoperative and first month postoperative were at the level of p 0.659, p=0.716, p=0.012; and the changes were not significant. It was determined that the changes in the TL, TK, CL, SVA, VAS and ODI values of the patients between preoperative and first month postoperative were at the level of p <0.001and the changes were significant. Conclusion: Vertebroplasty is an efficient technique for relieving pain in thoracic fractures that have a score of 4 and over, based on the thoracolumbar injury classification score and that are type A, based on the AO Spine thoracolumbar injury classification score. Elimination of pain in the acute period is effective in ameliorating the sagittal parameters of patients.

Integrated the Medical Procedure Analyze Seismic Resilience of Healthcare System: A Critical Review from the Resilience of Healthcare System vs. Medical Demand Perspective

The healthcare system is the bearer of treating the wounded and the victims of earthquakes. The functional integrity of the healthcare system is critical to the process of postearthquake medical rescue. Thus, the requirements for seismic resilience of the medical functions of the healthcare systems are increasing. Many studies have applied resilience research to address critical issues in the medical rescue of postearthquake casualties, such as medical diagnosis, emergency surgery, and intensive care. However, systematic construction is still lacking. System resilience is one of the most promising systemic management theories with great potential to address the abovementioned challenges. This article puts forward a scientific concept that system resilience can improve the efficiency of earthquake relief in medical rescue. Firstly, a scientific review of medical demand and medical resilience was conducted, summarizing resilience and resilience of healthcare system concepts. In addition, the postearthquake medical demand was reviewed, and the classification and distribution probability of postearthquake injuries were summarized. Furthermore, by reviewing the postearthquake medical rescue process, the weak points of each medical link were summarized. Combined with the key points in the medical rescue process, the application of resilience studies in the medical system is reviewed, and the progress of medical resilience is illustrated. In summary, combined with medical demand, the article provides some guidance for the deep integration between medical rescue processes and medical resilience and identifies the challenges of system resilience to reduce the waiting time of the injured future medical rescue in the earthquake.

Physeal injuries of the clavicle: pediatric counterparts to adult acromioclavicular and sternoclavicular joint separations.

The epiphyses at the medial and lateral ends of the clavicle are small, ossify relatively late, and may not fuse until early adulthood. Because of this unique anatomy, pediatric and young adult injuries that involve the clavicle often differ from the patterns typically seen in older adults. Clavicular trauma that affects the acromioclavicular joint laterally or sternoclavicular joint medially often results in a physeal fracture and as such, can go unrecognized or be mistaken for a joint dislocation. Radiographic assessment is challenging, particularly when the epiphysis is not yet ossified. However, MR imaging allows for visualization of the cartilage, periosteum and perichondrium, and ligaments of the affected joints. Lateral clavicle physeal injuries can be categorized by the Dameron and Rockwood system, the pediatric correlate to the Rockwood classification of adult acromioclavicular joint injuries. Medial clavicle physeal fractures, similar to adult sternoclavicular joint dislocations, may result in anterior or posterior displacement. Because of their great ability to heal and remodel, clavicular physeal fractures respond better to conservative management than true acromioclavicular or sternoclavicular joint dislocations. Therefore, it is essential to recognize the true nature of these injuries, as there are implications for successful treatment and appropriate prognosis.

The floating hip injury: a descriptive study and case-control analysis.

A "floating hip" (FH) injury is a rare injury describing the simultaneous ipsilateral fracture of the femur and pelvis or acetabulum (P/A). We describe our experience with patients presenting with FH injuries and compare them to controls with similar P/A fractures but without femoral involvement. Medical records and radiographs of FH patients and controls presenting to our tertiary centre between 2015 and 2020 were reviewed. Follow-up data from outpatient clinical records were also extracted. The control group were extensively matched by age, sex, body mass index, fracture classification and energy of injury. From 1392 recorded P/A fractures, 42 FH cases were identified (average age 39 years, 78.6% males). The most common femoral fracture was the midshaft (35.7%), followed by the neck of femur (26.2%). 90.5% of FH injuries were due to high-energy mechanisms. 64.3% of P/A fractures, and 100% of femoral fractures were managed surgically. Compared to controls, FH cases were more likely to have additional orthopaedic injuries (73.8% vs. 40.5%, p = 0.002), more total theatre admissions (mean 2.5 vs. 1.19, p < 0.001), longer hospital stays (28.3 vs. 14.9 days, p = 0.02), and a higher rates of post-op complications (53.8% vs. 20%, p = 0.025). We report differences in the presentation, management, and outcomes of FH injuries versus controls, even after extensive matching for confounders. These differences may inform future treatment strategies for the FH injury.

A survey of ASER members on artificial intelligence in emergency radiology: trends, perceptions, and expectations.

There is a growing body of diagnostic performance studies for emergency radiology-related artificial intelligence/machine learning (AI/ML) tools; however, little is known about user preferences, concerns, experiences, expectations, and the degree of penetration of AI tools in emergency radiology. Our aim is to conduct a survey of the current trends, perceptions, and expectations regarding AI among American Society of Emergency Radiology (ASER) members. An anonymous and voluntary online survey questionnaire was e-mailed to all ASER members, followed by two reminder e-mails. A descriptive analysis of the data was conducted, and results summarized. A total of 113 members responded (response rate 12%). The majority were attending radiologists (90%) with greater than 10years' experience (80%) and from an academic practice (65%). Most (55%) reported use of commercial AI CAD tools in their practice. Workflow prioritization based on pathology detection, injury or disease severity grading and classification, quantitative visualization, and auto-population of structured reports were identified as high-value tasks. Respondents overwhelmingly indicated a need for explainable and verifiable tools (87%) and the need for transparency in the development process (80%). Most respondents did not feel that AI would reduce the need for emergency radiologists in the next two decades (72%) or diminish interest in fellowship programs (58%). Negative perceptions pertained to potential for automation bias (23%), over-diagnosis (16%), poor generalizability (15%), negative impact on training (11%), and impediments to workflow (10%). ASER member respondents are in general optimistic about the impact of AI in the practice of emergency radiology and its impact on the popularity of emergency radiology as a subspecialty. The majority expect to see transparent and explainable AI models with the radiologist as the decision-maker.

Recent Progress in the Classification and Operation of Sacral Fractures.

Most sacral fractures are caused by high-energy, violent injuries, often accompanied by lumbosacral plexus injuries, which can cause instability of the posterior pelvic ring or lumbosacral junction in severe cases. Currently, the most commonly used clinical classification methods are Denis classification, Tile classification, Isler classification, and Denis II classification. In recent years, lumbosacral vertebral injury classification and injury degree scoring systems have often been applied clinically as the choice of treatment methods. At present, the internal fixation and implantation methods of sacral fracture are developing in the direction of positive, efficient, safe, and minimally invasive. But different fixation methods have their own indications, which should be strictly followed. This article reviews the classification of sacral fractures and the latest progress in surgical treatment.

Advances in the Restoration and Fixation of Lateral Femoral Wall Fracture

Hip fractures, especially intertrochanteric fractures, are more common with aging. After decades of progress, it is a general consensus to carry out internal fixation for this group of patients. However, the recent focus is on unstable intertrochanteric fractures to ensure better prognosis and prevent internal fixation failure. The lateral femoral wall, as a novel concept, is often disregarded. Many scholars have recognized that the lateral wall of the proximal femoral plays a crucial role in the stability of internal fixation for intertrochanteric fractures. In this paper, the historical evolution, definition, clinical significance, injury classification, choice of internal fixation, and possible prognosis of lateral femoral wall fracture are reviewed in order to provide clinicians strong evidence of treatment strategies.

Long term results and patient reported outcome measures following lisfranc injuries treated with memory staple fixation

IntroductionVarious modalities of fixation have been proposed for Lisfranc injuries. Memory staple fixation offers a simple option for transarticular fixation in suitable fracture configuration with no diaphyseal extension. However there is little evidence available in the literature regarding its efficacy and patient reported outcomes. Aim of the study was to present the long term outcomes of Lisfranc injuries treated with memory staple fixation and patient reported outcomes at average follow-up of four years. MethodThis was a retrospective analysis of all the patients who underwent fixation for Lisfranc injury using shape memory alloy (Nitinol) staples from December 2010 to October 2018. Patient demography, mechanism of injury, classification of Lisfranc injury, duration of followup, complication, revision surgery, implant removal and patient reported outcomes (AOFAS midfoot score) was noted. Results31 patients satisfied the inclusion criteria. Mean age was 50 years and 17 patients were females. 54 % patients reported low to moderate energy trauma which included simple fall from standing height or twisting injury. 28 (90.3 %) had B2 type of fracture pattern. 13 had fixation with staples only, 15 with a staple and home run screw. No patient had primary fusion. One patient had superficial infection treated with antibiotics only. Three patients developed symptomatic arthritis, out of which one proceeded to fusion. Six had implant removal for hardware related symptoms. Average AOFAS midfoot score at average four years follow-up was 77.8 which are satisfactory. ConclusionThis paper highlights good outcome following memory staple fixation for Lisfranc injuries. We believe staples are more suited for the dorsal buttressing that is typically required and provide stable, reproducible fixation Our findings also suggest less need for implant removal compared to transarticular screw or plate fixation though larger studies would be required to make definitive conclusions.

How are hamstring strain injuries managed in elite men's football clubs? A survey with 62 Brazilian physical therapists

ObjectiveTo describe perceptions and practices of physical therapists from elite men's football clubs on the management of athletes with hamstring strain injury (HSI). DesignCross-sectional study. SettingOnline survey. ParticipantsPhysical therapists from clubs engaged in the two main divisions of Brazilian men's football. Main outcome measuresPractices for assessment and rehabilitation of athletes with HSI. ResultsThis survey had 62 physical therapists from 35 of the 40 eligible clubs (87.5% representativeness). Despite heterogeneity on assessment practices, all respondents use imaging exams, adopt injury classification scales, and evaluate aspects related to pain, range of motion, muscle strength, and functional status of athletes with HSI. Rehabilitation programs are usually divided into 3 to 4 phases. All respondents usually apply electrophysical agents and stretching in HSI rehabilitation programs, 98.4% apply strengthening exercises (93.5% include eccentrics), 96.8% manual therapy, 95.2% exercises that mimic the functional demands of football, and 93.5% lumbopelvic stabilization exercises. Muscle strength was the most reported return to play criterion (71% of respondents). ConclusionThe present study allowed the sports physical therapy community to become aware of the approaches usually adopted for management of athletes with HSI who play in the highest level of Brazilian men's football.
