ABSTRACT

Abstract Objective We aim to describe an experimental model for studying femoral fractures in rats after exposure to ionizing radiation, demonstrating a way to apply a substance for analysis, the method for patterning fracture and irradiation, and how to evaluate its effectiveness based on radiographic studies. Methods We used 24 rats divided into 2 groups of 12 animals each. The STUDY group was exposed to ionizing radiation and treated with saline solution, and the CONTROL group was not exposed to radiation and was treated with saline solution. All animals were subjected to standardized fracture of the right femur that was fixed with intramedullary wire. The efficiency of the bone union was assessed by radiographic exam. Results Fracture healing was more efficient in bones not exposed to ionizing radiation (p = 0.012). All fractures met the criteria of being simple, diaphyseal, transverse or short oblique. Conclusion The experimental model presented is an efficient alternative for the study of fractures in irradiated bones in rats.


Resumo Objetivo Nosso objetivo é descrever um modelo experimental para estudo de fraturas de fêmur em ratos após exposição a radiação ionizante, demonstrando uma forma de aplicação de uma substância para análise, o método de padronização de fratura e irradiação e a forma de avaliação de sua eficácia com base em estudos radiográficos. Métodos Utilizamos 24 ratos divididos em dois grupos de 12 animais cada. O grupo ESTUDO foi exposto à radiação ionizante e tratado com soro fisiológico, enquanto o grupo CONTROLE não foi exposto à radiação e foi tratado com soro fisiológico. Todos os animais foram submetidos à fratura padronizada do fêmur direito e sua fixação com fio intramedular. A eficácia da consolidação óssea foi determinada por exame radiográfico. Resultados A cicatrização de fraturas foi mais eficiente em ossos não expostos à radiação ionizante (p = 0,012). Todas as fraturas atenderam aos critérios de serem simples, diafisárias, transversas ou oblíquas curtas. Conclusão O modelo experimental apresentado é uma boa alternativa para o estudo de fraturas em ossos irradiados em ratos.

ABSTRACT

Objetivos: compreender a experiência do idoso no restabelecimento da marcha após cirurgia de fratura de fêmur por queda e elaborar modelo teórico que a represente. Método: pesquisa qualitativa na abordagem da Teoria Fundamentada nos Dados, com saturação teórica, mediante a análise da transcrição da nona entrevista não diretiva audiogravada, com idosos que vivenciaram a experiência. CAAE 021.0.063.000-10. Resultados: emergiram três subprocessos: sentindo-se desafiado a recuperar a dignidade de desenvolver o autocuidado em situação de risco; perseverando em recursos psicossociais para reabilitar marcha ameaçada; resgatando a autoconfiança para deambular. Do realinhamento desses subprocessos, abstraiu-se a categoria central (processo), recursos psicossociais do idoso para reabilitar marcha e dignidade do autocuidado após fratura de fêmur. Conclusão: o modelo teórico emerso sinaliza a dignidade humana do autocuidado como preceito moral do idoso e ordenador no resgate da autoconfiança, perante as ameaças à reabilitação da marcha, apoiado em seus recursos psicossociais (família, religiosidade e reminiscência).(AU)


Objectives: to understand the experience of the elderly in reestablishing gait after surgery for a femur fracture due to a fall and to develop a theoretical model that represents it. Method: qualitative research in the Grounded Theory approach, with theoretical saturation, through the analysis of the transcription of the ninth audio-recorded non-directive interview, with elderly people who lived through the experience. CAAE 021.0.063.000-10. Results: three sub-processes emerged: feeling challenged to recover the dignity of developing self-care in a situation of risk; persevering in psychosocial resources to rehabilitate threatened gait; rescuing self-confidence to wander. From the realignment of these sub-processes, the central category (process), psychosocial resources of the elderly to rehabilitate gait and dignity of self-care after femur fracture was abstracted. Conclusion: the theoretical model emerged signals the human dignity of self-care as a moral precept of the elderly and ordering the recovery of self-confidence, in the face of threats to gait rehabilitation, supported by their psychosocial resources (family, religiosity and reminiscence).(AU)

ABSTRACT

Abstract Objective To evaluate the factors associated with readmission within 30 days after discharge (R30) and in-hospital mortality (IHM) in elderly patients undergoing proximal femur fracture surgery (PFF). Methods Retrospective cohort with data from 896 medical records of elderly (≥ 60 years) patients submitted to PFF surgery in a Brazilian hospital between November 2014 and December, 2019. The patients included were followed-up from the date of hospitalization for surgery up to 30 days after discharge. As independent variables, we evaluated gender, age, marital status, pre- and postoperative hemoglobin (Hb), international normalized ratio, time of hospitalization related to the surgery, door-surgery time, comorbidities, previous surgeries, use of medications, and the American Society of Anesthesiologists (ASA) score. Results The incidence of R30 was 10.2% (95% confidence interval [CI]: 8.3-12.3%), and the incidence of IHM was 5.7% (95%CI: 4.3-7.4%). Regarding R30, hypertension (odds ratio [OR]: 1.71; 95%CI: 1.03-2.96), and regular use of psychotropic drugs (OR: 1.74; 95%CI: 1.12-2.72) were associated in the adjusted model. In the case of IHM, higher chances were associated with chronic kidney disease (CKD) (OR: 5.80; 95%CI: 2.64-12.31), longer hospitalization time (OR: 1.06; 95%CI: 1.01-1.10), and R30 (OR: 3.60; 95%CI: 1.54-7.96). Higher preoperative Hb values were associated with a lower chance of mortality (OR: 0.73; 95%CI: 0.61-0.87). Conclusion Findings suggest that the occurrence of these outcomes is associated with comorbidities, medications, and Hb.


Resumo Objetivo Avaliar os fatores associados à reinternação em até 30 dias após a alta (R30) e à mortalidade intra-hospitalar (MIH) em idosos submetidos a cirurgia por fratura do fêmur proximal (FFP). Métodos Coorte retrospectiva com dados de 896 prontuários de idosos (≥ 60 anos) submetidos a cirurgia de FFP em hospital brasileiro, no período entre novembro de 2014 a dezembro de 2019. Os pacientes incluídos foram acompanhados desde a data de internação para a cirurgia até 30 dias após a alta. Como variáveis independentes, foram avaliados o sexo, idade, estado civil, hemoglobina (Hb) pré e pós-operatória, razão normalizada internacional, tempo da internação relacionada à cirurgia, tempo porta cirurgia, comorbidades, cirurgias prévias, uso de medicamentos e escore da American Society of Anesthesiologists (ASA). Resultados A incidência de R30 foi de 10,2% (intervalo de confiança [IC] 95%: 8,3-12,3%) e a de MIH foi 5,7% (IC95%: 4,3-7,4%). Referente a R30, no modelo ajustado, associaram-se ter hipertensão (odds ratio [OR]: 1,71; IC95%: 1,03-2,96), uso regular de medicamentos psicotrópicos (OR: 1,74; IC95%: 1,12-2,72). Tratando-se da MIH, maiores chances estiveram associadas à doença renal crônica (DRC) (OR: 5,80; IC95%: 2,64-12,31), maior tempo de internação (OR: 1,06; IC95%: 1,01-1,10) e R30 (OR: 3,60; IC95%: 1,54-7,96). Maiores valores de Hb pré-operatória associaram-se à menor chance de mortalidade (OR: 0,73; IC95%: 0,61-0,87). Conclusão Os achados sugerem que a ocorrência destes desfechos está associada à comorbidades, medicamentos e Hb.

Objetivos: Describir las complicaciones del trauma de guerra tras un año de manejo de pacientes con fracturas de fémur o tibia utilizando un protocolo de control de daños en el Hospital Militar Central, centro de referencia para este tipo de trauma en el país. Resultados: Se realizó una revisión retrospectiva de pacientes con fracturas femorales o tibiales por traumas de guerra entre 2012 y 2020, manejados con un protocolo de control de daños. Se seleccionaron 72 soldados, el 96% de las fracturas eran abiertas, el 91% (66 casos) sufrió alguna complicación, como lesión nerviosa, lesión vascular, defecto de cobertura, infección, falta de consolidación. Conclusiones: El trauma de guerra continúa representando una de las etiologías de politraumatismo en pacientes jóvenes de nuestro país que, a su vez, sigue teniendo grandes implicaciones clínicas y económicas. Las lesiones óseas de las extremidades requieren un manejo por etapas basado en la fijación externa según los principios de control de daños. Nivel de Evidencia: IV


Introduction: The Central Military Hospital of Bogotá, Colombia has a specialized team for treating war trauma patients. They conduct an initial assessment of patients and promptly manage potentially fatal injuries using a damage control approach that aims to save the patient's life, save the limb, and preserve its function. Materials and Methods: An observational, descriptive, cross-sectional study was conducted on patients from the Colombian armed forces who, between 2012 and 2020, had femur or tibia fractures as a result of war trauma; these patients were treated using external fixation by the orthopedics and traumatology service of the Central Military Hospital in Bogotá, Colombia. Objectives: To describe the complications associated with war trauma following a year of treatment for femur and/or tibia fractures under a damage control protocol at the Central Military Hospital, the nation's reference facility for this kind of trauma. Results:A retrospective review of war trauma patients between 2012 and 2020 with femoral or tibial fractures treated with DCO was performed. Fisher's Exact tests were used for comparisons. Seventy-two soldiers were selected, 96% of fractures were open, 91% (66 cases) had some type of complication such as nerve injury, vascular injury, coverage defect, infection, and nonunion. Conclusions: In our country, war trauma persists as one of the causes of polytrauma in young patients, which has significant clinical and financial implications. Bone injuries of severely affected extremities require staged management based on external fixation according to damage control principles. Level of Evidence: IV

ABSTRACT

Introducción: Cada vez con más frecuencia, la población civil sufre lesiones por proyectil de arma de fuego. El 57% de los pacientes presenta compromiso óseo y la fractura de fémur es la más común. La elevada incidencia y la ausencia de un protocolo estandarizado para su tratamiento motivaron este estudio. Materiales y Métodos: Estudio retrospectivo, descriptivo. Entre 2019 y 2021, se incluyeron pacientes con fracturas de fémur causadas por arma de fuego. Se analizaron las siguientes variables: región anatómica involucrada, clasificación, tratamiento y complicaciones. Resultados: La muestra incluyó a 35 pacientes, 25 (71,43%) con fracturas completas y 10 (28,57%), con fracturas incompletas. Según la localización, el fémur distal fue la zona más afectada (48,57%). Veintiséis pacientes fueron tratados mediante reducción y osteosíntesis y 9, de forma incruenta. Conclusiones: Recurrimos a una clasificación sencilla que divide a las fracturas en completas o incompletas. Todas las fracturas completas se consideraron inestables independientemente de su localización; y las incompletas, estables, salvo las del tercio proximal, donde es conveniente realizar una fijación profiláctica. Las fracturas diafisarias incompletas pueden tratarse de forma incruenta y todas las fracturas completas se trataron con reducción y osteosíntesis. El clavo endomedular es el método de elección para las fracturas en las zonas I y II. En la zona III, se requiere un análisis individualizado para cada patrón. Creemos que el manejo inicial y la correcta selección del implante según la zona afectada son factores determinantes para lograr resultados satisfactorios. Nivel de Evidencia: IV


Introduction: Gunshot injuries affect the civilian population with increasing frequency. 57% of the patients present bone compro-mise, with femur fractures being the most common. The lack of a standardized protocol for its treatment prompted the development of this study. Materials and Methods: A retrospective, descriptive study was conducted. Patients with femur fractures caused by firearms between 2019 and 2021 were included. The anatomical region, classification, treatment, and complications were analyzed. Results: Of a total of 35 patients, 25 (71.43%) had complete fractures and 10 (28.57%) had incomplete fractures. The distal femur was the most affected area (48.57%), according to the location. Reduction and osteosynthesis were used to treat 26 patients, with 9 being treated noninvasively. Conclusions: We used a simple classification system to categorize fractures as complete or incomplete. All complete ones were deemed unstable regardless of location, and all incomplete ones were deemed stable, with the exception of those in the proximal third, for which prophylactic fixation is advised. Incomplete shaft fractures can be treated noninvasively, but complete shaft fractures require reduction and osteosynthesis. For zone I and II fractures, the intramedullary nail is the preferred treatment. In zone III, an individualized analysis is required for each pattern. We believe that the initial management and the correct selection of the implant according to the affected area are decisive factors in achieving satisfactory outcomes. Level of Evidence: IV

ABSTRACT

OBJECTIVE: To investigate the use of sedatives by older adults attending a private outpatient geriatric clinic in Belo Horizonte (MG), Brazil, and its association with falls and hip fractures. METHODS: Using a longitudinal design, the prevalence of benzodiazepine and nonbenzodiazepine ("z-drugs") intake by older adults was described and their association with the incidence of falls and fractures (30 days after the initial visit) was evaluated through logistic regression. RESULTS: A total of 7821 older adults were included in the study, most of them women (72.50%), with a mean age of 77.5 years and a mean Clinical-Functional Vulnerability Index (IVCF-20) score of 16.5. The overall prevalence of sedative use (any sedative) was 6.19%, with 4.48% benzodiazepines and 1.98% z-drugs. The most widely used sedatives were clonazepam (29.04%), zolpidem (28.65%), and alprazolam (23.44%). Falls were reported for 182 patients (2.33%), with a higher incidence among users of any sedatives (4.34; p = 0.002; OR = 1.94, adjusted for sex, age, and IVCF-20) and benzodiazepines (5.14%; p < 0.001; OR = 2.28) than among non-users (2.19%). Hip fractures occurred in 33 patients (0.42%), and again were more frequent among users of sedatives (1.03%; p = 0.032; OR = 2.57) and benzodiazepines (1.43%; p = 0.003; OR = 3.45) than among non-users (0.38%). CONCLUSIONS: The use of sedatives, especially benzodiazepines, is associated with an increased incidence of falls and hip fractures in older adults


OBJETIVO: Investigar a utilização de sedativos entre idosos atendidos em ambulatório privado de geriatria em Belo Horizonte (MG), bem como sua associação com quedas e fraturas de fêmur. METODOLOGIA: Trata-se de estudo longitudinal, no qual foi descrita a prevalência de uso de benzodiazepínicos e drogas Z entre idosos (60 anos ou mais) e avaliada sua associação com a incidência de queda e fratura (30 dias após consulta inicial) por meio de regressão logística. RESULTADOS: Foram incluídos no estudo 7821 idosos, com maioria feminina (72,50%), idade média de 77,5 anos e Índice de Vulnerabilidade Clínico Funcional (IVCF-20) médio de 16,5 pontos. A prevalência de uso de sedativos em geral foi de 6,19%, sendo 4,48% de benzodiazepínicos e 1,98% de drogas Z. Os medicamentos sedativos mais utilizados foram clonazepam (29,04%), zolpidem (28,65%) e alprazolam (23,44%). Relatou-se queda para 182 idosos (2,33%), com incidência maior entre usuários de sedativos (4,34; p = 0,002; OR = 1,94 ajustada por sexo, idade e IVCF-20) e de benzodiazepínicos (5,14%; p < 0,001; OR = 2,28) do que entre não usuários (2,19%). Identificou-se fratura de fêmur em 33 idosos (0,42%), sendo mais frequente entre usuários de sedativos (1,03%; p = 0,032; OR = 2,57) e de benzodiazepínicos (1,43%; p = 0,003; OR = 3,45) do que entre não usuários (0,38%). CONCLUSÃO: Concluiu-se que a incidência de quedas e fraturas de fêmur em idosos possui associação com o uso de medicamentos sedativos, em especial os benzodiazepínicos

ABSTRACT

PURPOSE@#Long proximal femoral nail anti-rotation (PFNA-II) is a preferred implant in recent years for fixation of pertrochanteric fractures, especially in osteoporotic patients. The purpose of this study is to prospectively investigate the effect of distal locking in long PFNA-II fixation of stable intertrochanteric fractures.@*METHODS@#A total of 58 patients with isolated stable intertrochanteric fractures and treated in our hospital during the study period of 2017-2019 by distal locked or unlocked long PFNA-II fixation were included in this study. Patients who had multiple injuries or open fractures were excluded. There were 40 female and 18 male patients, with 33 affecting the left side and 25 the right side. Of them, 31 belonged to the distal locked group (group A) and 27 to the unlocked group (group B). Surgical procedures and implants used in both groups were similar except for the distal locking of the nails. General data (age, gender, fracture side, etc.) showed no significant difference between two groups (all p > 0.05). The intraoperative parameters like operative time, radiation exposure and follow-up parameters like functional and radiological outcomes were recorded and compared. Statistical tests like the independent samples t-test Fischer's exact and Chi-square test were used to analyze association.@*RESULTS@#The distribution of the fractures according to AO/OTA classification and 31A1.2 type of intertrochanteric fractures were most common in our study. All the included fractures united and the average functional outcome in both groups were good and comparable at the end of one year. The operative time (mL, 107.1 ± 12.6 vs. 77.0 ± 12.0, p < 0.001) and radiation exposure (s, 78.6 ± 11.0 vs. 40.3 ± 9.3, p < 0.001) were significantly less among the patients in group B. Fracture consolidation, three months after the operative procedures, was seen in a significantly greater proportion of patients in group B (92.6% vs. 67.7%, p = 0.025). Hardware irritation because of distal locking bolt was exclusively seen in group A, however this was not statistically significant (p = 0.241).@*CONCLUSION@#We conclude that, in fixation of stable intertrochanteric fractures by long PFNA-II nail, distal locking not only increases the operative time and radiation exposure but also delays the fracture consolidation and increases the chances of hardware irritation, and hence is not required.

ABSTRACT

OBJECTIVE@#To investigate the effect of treatment of Müller A fracture of distal femur with small incision internal fixation assisted by homeopathic bidirectional-traction reduction device.@*METHODS@#From January 2018 to December 2019, 22 patients (14 males and 8 females) with Müller type A distal femoral fractures were treated with homeopathic bidirectional-traction assisted reduction and minimally invasive small incision locking plate internal fixation;The age ranged from 29 to 58 years old with an average of (41.23±7.03) years. The time from injury to operation was 1 to 7 days with an average of (3.41±1.71) days. According to Müller classification, there were 4 cases of type A1, 10 cases of type A2, and 8 cases of type A3. The postoperative knee joint function was evaluated by Schatzker Lambert fracture criterion of distal femur.@*RESULTS@#All the incisions healed in one stage without infection, osteomyelitis and other complications. All the fractures healed without malunion and nonunion. All of 22 patients were followed up for 12 to 18 months with an average of (14.50±2.02) months. The healing time was 3 to 6 months with an average of (4.64±1.14) months. According to Schatzker Lambert criteria for distal femoral fracture, 12 cases were excellent, 6 good, and 4 medium.@*CONCLUSION@#It is an ideal method to treat Müller type A fracture of distal femur with homeopathic bidirectional-traction assisted reduction device and minimally invasive small incision locking plate internal fixation.

ABSTRACT

Femoral head and ipsilateral femoral neck fractures are serious and complicated injuries, which usually yield unsatisfactory results using conventional hip-preserving surgery. The key point of the management and prognosis mainly lies in femoral neck fractures. An apparent and consecutive relationship exists between femoral neck fractures and femoral head fracture-hip dislocation in such injuries. It is believed that disastrous triad of femoral head (DTFH) could summarize these specific injuries, and reflect the injury mechanism and prognostic characteristics. Based on our clinical observation and literature review, DTFH could be divided into three subgroups:TypeⅠ, common DTFH, in which femoral neck fractures occur following femoral head fractures-hip dislocation due to the same trauma; TypeⅡ, iatrogenic DTFH, in which femoral neck fractures come out in the caring process of femoral head fractures-hip dislocation; Type Ⅲ, stressed DTFH, in which femoral neck fractures occur after the management of femoral head fractures-hip dislocation. In the scenario, the line of femoral neck fractures locates distally to the femoral head fractures. Herein, we will discuss clinical characteristics of these types of DTFH.

ABSTRACT

OBJECTIVE@#To retrospectively analyze efficacy of single structure internal fixation and double structure internal fixation in the treatment of ipsilateral femoral shaft and neck fracture, and analyze their indications.@*METHODS@#From June 2015 to December 2020, 21 patients with ipsilateral femoral shaft and femoral neck fracture were treated, including 14 males and 7 females, aged 23 to 69 years old with an average of(38.1±12.9) years old. According to different femoral shaft fracture sites, some patients were fixed with cephalomedullary implant for both femoral neck and the femoral shaft(single structure, InterTan or PFNA Ⅱ), some patients were fixed with cannulated screws for the femoral neck and a retrograde locking nail for the femoral shaft (dual structure), and postoperative function and complications were recorded during follow-up. In 10 cases of single-structure fixation, the femoral necks were all basicervical fractures, and the femoral shaft fractures were located in the proximal isthmus;11 cases were double-structure fixation, 9 cases in 11 were basal type of femoral neck, 2 cases in 11 were neck type, and the femoral shaft fractures were located in the isthmus and the distal isthmus.@*RESULTS@#All patients were followed up for 12 to 27 months. No femoral head necrosis, deformity, delay or nonunion occurred in the patients with single-structure fixation, and no delayed union or nonunion occurred in femoral shaft fractures;At the final follow-up, Harris score of patients with single-structure fixation was 91.8±4.1, with 8 cases were excellent and 2 cases were good. The fractures of patients with dual-structure fixation achieved good union without femoral head necrosis, except 1 case of femoral shaft fracture had delayed union;At the final follow-up, Harris score of patients with dual-structure fixation was 92.4±5.9, 7 cases were excellent, 3 cases were good, and 1 case was fair.@*CONCLUSION@#Good reduction and fixation is the key to the treatment of such fractures. Both the single-structure fixation and the dual-structure fixation are good methods, and it should be selected according to the locations of femoral shaft and femoral neck fractures. Single-structure fixation is a good choice for femoral shaft fractures located at the proximal isthmus and basal femoral neck fractures. For isthmus and distal femoral shaft fractures combined with ipsilateral femoral neck fractures, dual-structure fixation is recommended.

ABSTRACT

PURPOSE@#Non-prosthetic peri-implant fractures are challenging injuries. Multiple factors must be carefully evaluated for an adequate therapeutic strategy, such as the state of bone healing, the type of implant, the time and performed personnel of previous surgery, and the stability of fixation. The aim of this study is to propose a rationale for the treatment.@*METHODS@#The peri-implant femoral fractures (PIFFs) system, a therapeutic algorithm was developed for the management of all patients presenting a subtype A PIFF, based on the type of the original implant (extra- vs. intra-medullary), implant length and fracture location. The adequacy and reliability of the proposed algorithm and the fracture healing process were assessed at the last clinical follow-up using the Parker mobility score and radiological assessment, respectively. In addition, all complications were noticed. Continuous variables were expressed as mean and standard deviation, or median and range according to their distribution. Categorical variables were expressed as frequency and percentages.@*RESULTS@#This is a retrospective case series of 33 PIFFs, and the mean post-operative Parker mobility score was (5.60 ± 2.54) points. Five patients (15.1%) achieved complete mobility without aids (9 points) and 1 (3.0%) patient was not able to walk. Two other patients (6.1%) were non-ambulatory prior to PPIF. The mean follow-up was (21.51 ± 9.12) months (range 6 - 48 months). There were 7 (21.2%) complications equally distributed between patients managed either with nailing or plating. There were no cases of nonunion or mechanical failure of the original implant.@*CONCLUSION@#The proposed treatment algorithm shows adequate, reliable and straightforward to assist the orthopaedic trauma surgeon on the difficult decision-making process regarding the management of PIFF occurring in previously healed fractures. In addition, it may become a useful tool to optimize the use of the classification, thus potentially improving the outcomes and minimizing complications.

ABSTRACT

OBJECTIVE@#The biomechanical characteristics of three internal fixation modes for femoral subtrochanteric spiral fracture in osteoporotic patients were compared and analyzed by finite element technology, so as to provide the basis for the optimization of fixation methods for femoral subtrochanteric spiral fracture.@*METHODS@#Ten female patients with osteoporosis and femoral subtrochanteric spiral fractures caused by trauma, aged 65-75 years old, with a height of 160-170 cm and a body weight mass of 60-70 kg, were selected as the study subjects. The femur was scanned by spiral CT and a three-dimensional model of the femur was established by digital technology. The computer aided design models of proximal intramedullary nail (PFN), proximal femoral locking plate (PFLP), and the combination of the two (PFLP+PFN) were constructed under the condition of subtrochanteric fracture. Then the same load of 500 N was applied to the femoral head, and the stress distribution of the internal fixators, the stress distribution of the femur, and the displacement of femur after fracture fixation were compared and analyzed under the three finite element internal fixation modes, so as to evaluate the fixation effect.@*RESULTS@#In the PFLP fixation mode, the stress of the plate was mainly concentrated in the main screw channel, the stresses of the different part of the plate were not equal, and gradually decreased from the head to the tail. In the PFN fixation mode, the stress was concentrated in the upper part of the lateral middle segment. In the PFLP+PFN fixation mode, the maximum stress appeared between the first and the second screws in the lower segment, and the maximum stress appeared in the lateral part of the middle segment of the PFN. The maximum stress of PFLP+PFN fixation mode was significantly higher than that of PFLP fixation mode, but significantly lower than that of PFN fixation mode ( P<0.05). In PFLP and PFN fixation modes, the maximum stress of femur appeared in the medial and lateral cortical bone of the middle femur and the lower side of the lowest screw. In PFLP+PFN fixation mode, the stress of femur concentrated in the medial and lateral of the middle femur. There was no significant difference in the maximum stress of femur among the three finite element fixation modes ( P>0.05). The maximum displacement occurred at the femoral head after three finite element fixation modes were used to fix subtrochanteric femoral fractures. The maximum displacement of femur in PFLP fixation mode was the largest, followed by PFN, and PFLP+PFN was the minimum, with significant differences ( P<0.05).@*CONCLUSION@#Under static loading conditions, the PFLP+PFN fixation mode produces the smallest maximum displacement when compared with the single PFN and PFLP fixation modes, but its maximum plate stress is greater than the single PFN and PFLP fixation mode, suggesting that the combination mode has higher stability, but the plate load is greater, and the possibility of fixation failure is higher.

ABSTRACT

Total hip arthroplasty (THA) is a safe and effective procedure in patients with end-stage ostheoarthritis. In the last years the indication for THA is increasingly in younger patients, associated with rising of life expectancy, this imply an increase in revision surgeries for various causes such as: aseptic loosening, fractures and infections. In this context and in view of the need to replace the femoral component, alternatives to the classic extended trochanteric osteotomy (ETO) arise, such as the anterior cortical window (ACW), which allows the rate of complications to be reduced with excellent results. We present the case of a 51-year-old patient who sustained one episode of dislocation, who required revision surgery due to aseptic loosenig, where the ACW was used for the extraction of the stem. In addition, a review of the literature was made to show advantages and complications regarding ETO.

ABSTRACT

Introducción: Las fracturas de la diáfisis femoral son lesiones que requieren gran energía y a menudo asocian otras lesiones. Este es el caso de las lesiones ligamentarias de rodilla, las cuales pueden pasar desapercibidas por el equipo médico tratante. El objetivo de nuestro trabajo es revisar la literatura existente sobre esta asociación lesional. Dentro de la misma se buscará la metodología diagnóstica utilizada y la incidencia de las lesiones ligamentarias. Materiales y métodos: Se realizó una búsqueda bibliográfica de forma sistematizada a través de los portales de búsqueda PubMed y Timbó. La búsqueda alcanzó un total de 3099 artículos y de acuerdo a los criterios de inclusión y exclusión se seleccionaron 15 trabajos. Resultados: Los diferentes artículos utilizaron examen físico bajo anestesia, radiografías en estrés, artroscopía o resonancia nuclear magnética para establecer el diagnóstico de las lesiones ligamentarias asociadas a las fracturas de diáfisis femoral. Un 22,5% de las fracturas femorales asoció lesión ligamentaria de rodilla, siendo la lesión del ligamento cruzado anterior el 34% de las lesiones reportadas. Discusión: Se evidencia una gran variabilidad en la incidencia de lesiones ligamentarias y de cuál es el ligamento más frecuentemente lesionado, yendo desde 5,3% a 52,5% en estudios tanto retrospectivos como prospectivos con bajos números de pacientes. Se plantea un algoritmo diagnóstico para los pacientes que puedan presentar esta asociación lesional, para evitar que los mismos pasen desapercibidos al equipo médico tratante. Logrando un diagnóstico precoz se puede mejorar el pronóstico de estos pacientes. Conclusión: De nuestra revisión se desprende que en el contexto de una fractura de diáfisis femoral un 22,5% de los pacientes presenta lesiones ligamentarias de rodilla con un 34% de compromiso del LCA. Sin embargo, estas cifras son muy variables en los distintos trabajos. Por esta razón, creemos necesario llevar a cabo un estudio prospectivo con mayor número de pacientes para lograr valorar la verdadera epidemiología de estas lesiones.


Introduction: Femoral shaft fractures require great energy and are often associated with other injuries. This is the case of knee ligament injuries, which can go unnoticed by the treating physician The objective of our work is to review the existing literature on this injury association. Within it, the diagnostic methodology used and the incidence of ligamentous injuries will be sought. Materials and methods: A bibliographic search was carried out in a systematic way through the search portals PubMed and Timbó. The search reached a total of 3099 articles and according to the inclusion and exclusion criteria, 15 works were selected. Results: The different articles used physical examination under anesthesia, stress radiographs, arthroscopy or magnetic resonance imaging to establish the diagnosis of ligamentous injuries associated with femoral diaphysis fractures. 22.5% of femoral fractures were associated with knee ligament injury, with anterior cruciate ligament accounting for 34% of reported injuries. Discussion: There is evidence of a great variability in the incidence of ligament injuries and which is the most frequently injured ligament, ranging from 5.3% to 52.5% in both retrospective and prospective studies with low numbers of patients. A diagnostic algorithm is proposed for patients who may present this lesional association, to prevent them from going unnoticed by the treating medical team. Achieving an early diagnosis can improve the prognosis of these patients. Conclusion: Our review shows that in the context of a femoral diaphysis fracture, 22.5% of patients present knee ligament injuries with 34% of ACL involvement. However, these figures are highly variable in the different studies. For this reason, we believe it is necessary to carry out a prospective study with a larger number of patients in order to assess the true epidemiology of these lesions.


Introdução: As fraturas da diáfise do fêmur são lesões que requerem grande energia e muitas vezes estão associadas a outras lesões. É o caso das lesões ligamentares do joelho, que podem passar despercebidas pela equipe médica que o trata. O objetivo do nosso trabalho é revisar a literatura existente sobre essa associação lesional. Dentro dele, será buscada a metodologia diagnóstica utilizada e a incidência de lesões ligamentares. Materiais e métodos: Foi realizada uma busca bibliográfica de forma sistemática através dos portais de busca PubMed e Timbó. A busca atingiu um total de 3099 artigos e de acordo com os critérios de inclusão e exclusão, 15 trabalhos foram selecionados. Resultados: Os diferentes artigos utilizaram o exame físico sob anestesia, radiografias de estresse, artroscopia ou ressonância magnética para estabelecer o diagnóstico de lesões ligamentares associadas às fraturas da diáfise do fêmur. 22,5% das fraturas do fêmur foram associadas à lesão ligamentar do joelho, sendo a lesão do ligamento cruzado anterior responsável por 34% das lesões relatadas. Discussão: Há evidências de uma grande variabilidade na incidência de lesões ligamentares e qual é o ligamento mais frequentemente lesado, variando de 5,3% a 52,5% em estudos retrospectivos e prospectivos com baixo número de pacientes. Um algoritmo diagnóstico é proposto para os pacientes que podem apresentar essa associação lesional, para evitar que passem despercebidos pela equipe médica responsável. O diagnóstico precoce pode melhorar o prognóstico desses pacientes. Conclusão: Nossa revisão mostra que no contexto de fratura da diáfise do fêmur, 22,5% dos pacientes apresentam lesões ligamentares do joelho com 34% de envolvimento do LCA. No entanto, esses números são altamente variáveis ​​nos diferentes estudos. Por esse motivo, acreditamos ser necessário realizar um estudo prospectivo com um número maior de pacientes para avaliar a verdadeira epidemiologia dessas lesões.

ABSTRACT

Abstract Objective To estimate the frequency of Staphylococcus aureus and cephalosporin nonsusceptible bacteria colonization in patients with proximal femoral fracture during preoperative hospitalization. Methods Prevalence and incidence assessment in 63 hospitalized patients over 1 year. The median time of pretreatment hospitalization was 12 days. Samples were collected from the nostrils, groin skin and anal mucosa during the pretreatment hospitalization and were tested by the disc-diffusion technique. Results The hospital colonization incidence and the prevalence of positive results were 14.3 and 44.4% for S. aureus; 3.2 and 6.4% for meticillin-resistant S. aureus; 28.6 and 85.7% for meticillin-resistant coagulase-negative Staphylococcus; 28.6 and 61.9% for cefazolin nonsusceptible Enterobacteriaceae (KFNSE); and 20.6 and 28.6% for cefuroxime nonsusceptible Enterobacteriaceae (CXNSE). In addition, factors such as to the duration of the pretreatment hospitalization period, being non-walker before fracture, antimicrobial use, American Society of Anesthesiologists (ASA) 4 surgical risk, and previous hospitalization, were related to an increase in the incidence of hospital acquisition and prevalence of colonization by the evaluated strains. The prevalence of colonization by KFNSE was three times higher than by CXNSE on admission, and twice as high at the time of fracture treatment. Conclusion There was a high incidence of hospital colonization and prevalence of colonization by all strains studied, which may guide the indication of prophylactic measures for infection.


Resumo Objetivo Estimar a frequência da colonização por Staphylococcus aureus e as bactérias não suscetíveis à cefalosporina, em pacientes com fratura proximal do fêmur durante a internação pré-operatória. Métodos Avaliação da prevalência e incidência em 63 pacientes hospitalizados ao longo de um ano. O tempo médio de internação pré-tratamento foi de 12 dias. As amostras foram coletadas das narinas, pele da virilha e mucosa anal, durante a internação prévia ao tratamento e testadas pela técnica de disco-difusão. Resultados A incidência da colonização hospitalar e a prevalência de resultados positivos foram de 14,3% e 44,4% para Staphylococcus aureus; 3,2% e 6,4% para S. aureus resistente à meticilina; 28,6% e 85,7% para Staphylococcus coagulase-negativo resistente à meticilina; 28,6% e 61,9% para Enterobacteriaceae não suscetível à cefazolina (KFNSE); e 20,6% e 28,6% para Enterobacteriaceae não suscetível à cefuroxima (CXNSE). Além da duração do período de internação pré-tratamento, os pacientes não deambularam previamente à ocorrência da fratura e nem fizeram uso de antimicrobiano. Além disso, a duração do período de internação pré-tratamento cirúrgico, ser não-deambulador antes da fratura, uso de antimicrobianos, risco cirúrgico IV pela American Society of Anesthesiologists (ASA) e internação anterior, estiveram relacionados a um aumento na incidência de aquisição hospitalar e prevalência de colonização pelas cepas avaliadas. A prevalência de colonização pela KFNSE foi três vezes maior do que pela CXNSE na admissão e duas vezes maior no momento do tratamento da fratura. Conclusão Observou-se uma alta incidência da colonização hospitalar e prevalência da colonização por todas as cepas estudadas, o que pode orientar a indicação de medidas profiláticas contra a infecção.

ABSTRACT

Abstract Objective The present study aims to describe outcomes from a series of surgically treated patients with atypical femoral fracture due to bisphosphonates use, in addition to correlate the time of previous medication use with fracture consolidation time, and to compare the consolidation time of complete and incomplete fractures. Methods This is an observational, retrospective study with 66 patients diagnosed with atypical femur fractures associated with chronic bisphosphonates use. The patients underwent orthopedic surgical treatment at a referral hospital from January 2018 to March 2020. Results All patients were females, with two bilateral cases. Fracture consolidation occurred in all cases, with an average time of 2.3 months and a follow-up time of 5.8 months. The average time of bisphosphonates use was 7.8 years. There was no correlation between the time of previous bisphosphonates use and the time for fracture consolidation. Consolidation time differed in complete and incomplete fractures. Conclusion Surgical treatment with a long cephalomedullary nail resulted in consolidation in all patients. The consolidation time was longer in complete fractures when compared with incomplete lesions, and there was no correlation between the time of previous bisphosphonates use and the consolidation time . Level of evidenceLevel IV, case series

ABSTRACT

Introducción: Nuestro objetivo fue analizar los resultados del tratamiento con osteosíntesis en pacientes con fracturas Vancouver tipos B1 y C, evaluar las complicaciones, las reintervenciones y la tasa de mortalidad en este grupo. Materiales y métodos: Estudio multicéntrico, retrospectivo. Se estableció una base de datos que incluía a 53 pacientes con fracturas periprotésicas de fémur Vancouver tipos B1 y C tratadas con osteosíntesis, desde 2008 hasta 2021, en dos centros hospitalarios de alta complejidad. Resultados: La fijación proximal más utilizada fue con tornillos bicorticales más lazadas de alambre. El tipo de fractura según la clasificación de Vancouver se correlacionó con un valor significativo en el uso de tornillos de compresión interfragmentaria (p 0,001), con un total de 13 pacientes (24,52%), 9 en fracturas Vancouver tipo C. El tiempo de consolidación promedio fue de 4 meses, con un puntaje promedio del Harris Hip Score de 68. Doce pacientes (22,64%) tuvieron complicaciones: retraso de la consolidación (7 casos; 13,2%), falla de la osteosíntesis con trazo de fractura a nivel distal del tallo (un caso; 1,88%), una nueva osteosíntesis por falla a nivel del material de osteosíntesis (un caso; 1,88%) y tres fallecieron (5,66%). Conclusiones: El manejo de las fracturas femorales periprotésicas es un tema complejo y desafiante. El tratamiento con osteosíntesis constituye un método exitoso que requiere de la aplicación de principios actuales de técnicas mínimamente invasivas que, junto con una fijación proxi-mal estable, mejoran las posibilidades de éxito. Nivel de Evidencia: IV


Introduction: Our objective was to analyze the results of osteosynthesis treatment in patients with Vancouver type B1 and C fractures, evaluate complications, reinterventions and the mortality rate in this group. Materials and methods: Multicenter, retrospective study. A database was established that included 53 patients with Vancouver type B1 and C periprosthetic femoral fractures treated with osteosynthesis, from 2008 to 2021, who were evaluated in two high-complexity hospital centers. Results: The most used proximal fixation was bicortical screws and wire loops. The type of fracture according to the Vancouver classification correlated with a significant value in the use of interfragmentary compression screws (p 0.001), with a total of 13 patients (24.52%), 9 in Vancouver type C fractures. Mean consolidation was 4 months, with a mean Harris Hip Score of 68. Twelve patients (22.64%) had complications: delayed union (7 cases; 13.2%), failed osteosynthesis with fracture at the distal level of the stem (one case; 1.88%), one new osteosynthesis due to failure at the level of the osteosynthesis material (one case; 1.88%) and three patients died (5.66%). Conclusions: The management of periprosthetic femoral fractures is a complex and challenging issue. Osteosynthesis treatment is a successful method that requires the application of current principles of minimally invasive techniques that, together with stable proximal fixation, improve the chances of success.

ABSTRACT

Las fracturas de fémur distal, especialmente las abiertas, se asocian con traumas de alta energía. Las lesiones asociadas al-rededor de la rodilla son frecuentes; sin embargo, la asociación con una lesión completa del tendón cuadricipital ha sido poco documentada. El diagnóstico temprano y un adecuado tratamiento de ambas lesiones son fundamentales para conseguir buenos resultados posoperatorios. Presentamos dos casos de fracturas intrarticulares de fémur distal expuestas asociadas con lesiones completas del tendón cuadricipital. La reparación de la lesión tendinosa asociada mediante túneles transóseos luego de la fijación de la fractura permite comenzar un protocolo de rehabilitación temprano, esencial para obtener buenos resultados funcionales.Palabras clave: Fractura; fémur distal; lesión; tendón cuadricipital; aparato extensor. Nivel de Evidencia: V


Fractures of the distal femur, especially open fractures, occur in association with high-energy trauma. The presence of associated injuries around the knee is common; however, the association with a complete quadricipital tendon injury has been poorly documented. Early diagnosis and adequate treatment of both injuries is essential to achieve good postoperative outcomes. We present two cases of exposed intra-articular distal femoral fractures associated with complete quadricipital tendon injuries. The repair of the associated tendon injury with transosseous tunnels after fracture fixation allows an early rehabilitation protocol, essential to obtain good functional outcomes.Key words:Fracture; distal femur; injury; quadricipital tendon; extensor mechanism.
