Modified-tension band suturing: 'the pulling the reins technique' - a technique for displaced proximal humeral fracture with medial column instability.

Fractures of the proximal humerus with medial column instability are challenging and present an unacceptable rate of complications and reoperations. Despite good results reported with the use of locking plates and augmentation techniques using bone graft or a second plate, varus subsidence and fixation failure have been frequently reported. We describe the case of a patient presenting with a complex, multifragmentary proximal humerus fractures successfully treated with open anatomic reduction and internal fixation using a locking plate augmented with lateral traction using three bone anchors in the humerus head. After 18 months, the patient reported fully recovering the mobility and functionality of the operated shoulder. The use of bone anchors pulling the humeral in three different directions like three vectors applied from medial to lateral, posterior to anterior and lateral to anterior help to reduce the most important deformities (varus and retroversion) by applying the tension band principle. This is an interesting approach to avoid primary and secondary reduction loss of the proximal fractures of the humerus with postero-medial cortical defect. The procedure is a good alternative to be used in patients with failure or insufficiency of the medial wall and marked varus.

Standing on shoulder of giants: the incredible legacy of the Judet family in orthopaedic surgery.

In orthopaedic surgery, as well as other areas in medicine, it is common for a surgical technique to carry the original authors' name describing the procedure. The Judet family represents a unique history, since several orthopaedic procedures are known as "Judet's technique". The aim of this historic review is to outline the genealogy of the orthopaedic arm of the Judet family, while crediting each surgical procedure to the specific family member that described the technique.

Leadership development training for brazilian orthopedic surgeons / Treinamento de desenvolvimento de liderança para cirurgiões ortopédicos brasileiros

ABSTRACT Objective: To report on the experience and impressions of the Brazilian orthopedic trauma surgeons attending the Leadership Development Program (LDP) hosted by the Sociedade Brasileira do Trauma Ortopédico (SBTO) in Sao Paulo, Brazil on November 4, 2022. Methods: Forty-eight orthopedic trauma surgeons from five different regions throughout Brazil were provided a link to complete The Big Five Test, a validated online personality assessment. The questionnaire was available in Portuguese and was intended to provide a background on individual personality traits and their influence on interpersonal interactions. The LDP integrated content from literature reviews specific to Latin America, established leadership programs from leading business schools, and various subject matter experts. Prior to the start of the LDP, participants received a pre-course survey evaluating demographic information, a needs assessment, and the prioritization of leadership topics utilizing a 5-point Likert-scale. Attendees participated in the one-day, interactive LDP focusing on the fundamental principles of leadership development, communication, personal development, emotional intelligence and negotiation. Following the LDP, a post-course evaluation was administered to determine the participants' overall experience, and suggestions for LDP improvement. Results: Forty-one of the forty-eight course participants completed the pre-course evaluation, whereas forty-six of the forty-eight participants completed the post-course evaluations. Overwhelmingly, the lack of opportunity was most prevalently reported as the main obstacle to attending a leadership course, as cited by 56% of respondents. Conclusion: Expanding the accessibility, diversity, and customizability of leadership programs can facilitate the development of personal tools needed to move healthcare forward. Critical topics include emotional intelligence and other differentiating leadership qualities that distinguish true transformational and servant leaders. Advancing leadership skills can stimulate networking, expose learners to experiential learning styles, inspire others to create positive change, and engender creative solutions for systematic improvements and health outcomes.

Open reduction and internal fixation of Ideberg type IA glenoid fractures: Tricks, pearls, and potential pitfalls based on a retrospective cohort of 33 patients focusing on the rehabilitation protocol.

INTRODUCTION: The standard treatment of anterior glenaoid fractures carrying > 20% of the glenoid fossa is open reduction and internal fixation (ORIF). In the herein study, we report our outcomes in a retrospective cohort of anterior and anteroinferior glenoid rim fractures using an accelerated postoperative rehabilitation protocol. A secondary aim is to describe the surgical steps for ORIF of anterior and anteroinferior glenoid rim fractures using the anterior axillary approach, describing the tricks, pearls, and pitfalls of this surgical technique. METHODS: A retrospective cohort of skeletally mature patients treated for an anterior glenoid rim fracture carrying > 20% of the glenoid fossa during a 10-year period were operated on using a vertical axillary incision, osteosynthesis with 2.0-mm cortical screws, and labral repair with small diameter metallic anchors and non-absorbable sutures. Rehabilitation began on the first postoperative day, including passive external rotation exercises and active-assisted flexion, adduction, and abduction exercises as tolerated. The exercises are performed with the patient sitting or lying down. Phase 1 is continued for 6-10 weeks until the patient regains painless, normal, or near-normal ROM. Usually by 10 weeks, the fracture and labrum are healed, so phase 2 rehabilitation begins with strengthening and ROM exercises. Radiologic and clinical outcomes, including active range of motion (ROM), glenohumeral stability, and visual analogue scale (VAS) were measured. RESULTS: About 33 patients (35 fractures) had complete medical records and pre- and post-operative imaging exams available for further analysis regarding the surgical protocol, with a mean of 4.8 years. The mean DASH questionnaire was 3.75 ± 9.0 and the mean CM score was 62.5 ± 0.1. Active flexion and internal rotation were recovered in all patients, while external rotation presented an average loss of 8° (p = 0.12) and abduction of 5° (p = 0.33). The mean VAS was 1.1 ± 0.8. No patient reported major or disabling symptoms, or great difficulty or inability to perform daily or recreational activities. No patient presented residual instability of the glenohumeral joint. CONCLUSION: In this retrospective cohort, ORIF using a vertical axillary incision, osteosynthesis with 2.0-mm screws, and labral repair with small diameter metallic anchors and non-absorbable sutures was a safe approach, with a minimal risk of complications and residual instability. The accelerated postoperative rehabilitation protocol, allowing immediate passive external rotation of the operated shoulder, resulted in a non-significant loss of ROM compared to the contralateral side. Therefore, we recommend this management strategy for anterior glenoid rim fractures in patients with unstable shoulder joint after traumatic glenohumeral dislocation.

Epidemiological and Clinical Profile of Patients Submitted to Total Knee Arthroplasty / Perfil epidemiológico e clínico dos pacientes submetidos a artroplastia total do joelho

Abstract Objective To define the epidemiological profile and the associated comorbidities of patients submitted to total knee arthroplasty (TKA) in two reference hospitals. Methods During the present cross-sectional observational study, 294 patients submitted to TKA were evaluated in 2 tertiary care hospitals. The diagnosis of selfreported comorbidities was collected by direct interview. The Functional Comorbidity Index (FCI) and the 5-Factor Modified Frailty Index (mFI-5) were calculated. The incidence of comorbidities and their relationship with the calculated indexes were evaluated. Results Most of the patients in the sample were women (p» 0.000) between the seventh and eighth decades of life. Systemic arterial hypertension was the most common pathology, followed by obesity and diabetes mellitus. The FCI presented a direct relationship with females (p» 0.038) and obesity (p< 0.001). The mFI-5 was only associated to obesity (p» 0.022), demonstrating a higher chance of complications in this group. Conclusion Patients undergoing TKA are essentially carriers of clinical comorbidities that can negatively influence functional results and compromise the safety of the procedure. The identification of risk factors can contribute to the safety and better selection of TKA candidates.

Resumo Objetivo Definir o perfil epidemiológico e as comorbidades associadas dos pacientes submetidos à artroplastia total do joelho (ATJ) em dois hospitais de referência. Métodos Durante o estudo observacional transversal, foram avaliados 294 pacientes submetidos à ATJ em 2 hospitais de atenção terciária. Coletou-se, por entrevista direta, o diagnóstico das comorbidades auto-relatadas. Foram calculados o índice de comorbidades funcionais (do inglês Functional Comorbidity Index, FCI) e o índice modificado de cinco fatores de fragilidade (do inglês 5-Factor Modified Frailty Index, mFI-5). Avaliou-se a incidência das comorbidades e a relação destas com os índices calculados. Resultados A maioria dos pacientes da amostra foram mulheres (p» 0,000) entre a sétima e oitava décadas de vida. A hipertensão arterial sistêmica foi a patologia mais comum, seguida de obesidade e diabetes mellitus. O ICFapresentou uma relação direta com sexo feminino (p» 0,038) e a obesidade (p< 0,001). O mFI-5 apresentou relação somente com a obesidade (p» 0,022), e demonstrou uma chance maior de complicações nesse grupo. Conclusão Os pacientes submetidos à ATJ são essencialmente portadores de comorbidades clínicas que podem influenciar negativamente os resultados funcionais e comprometer a segurança do procedimento. A identificação dos fatores de risco pode contribuir para a segurança e melhor seleção dos candidatos a ATJ.

Pre-contoured superior locking plates offer poor bone fit for midshaft clavicle fracture fixation: cadaveric analysis of 4 commercially available systems / Placas pré-moldadas superiores possuem adaptação ruim para fixação de fraturas do terço médio da clavícula: análise cadavérica de quatro sistemas disponíveis comercialmente

ABSTRACT Objective: The goal of this study is to verify how commercially available pre-contoured superior plates fit on clavicle midshaft fractures. Methods: 100 cadaveric clavicles were evaluated by three distinct observers applying the clavicle congruence score and comparing four different 6 to 8-hole pre-contoured anatomic locking-plate systems. Results: the inter-observer agreement was considered moderate by the percentage agreement and fair by the Fleiss' Kappa, with no significant differences between evaluations. Only 1 of the 8 plates presented an anatomic fit greater than 70%. Long plates (8 holes) presented a poor fit compared to short plates (6 or 7 holes). Conclusions: the overall evaluation showed that currently-available pre-contoured superior plate systems provide a poor fit on clavicles for midshaft fracture fixations. Long plates present a worse fit compared to short ones.

RESUMO Objetivo: verificar como as placas superiores pré-moldadas disponíveis no mercado se adaptam às fraturas do terço médio da clavícula. Método: 100 clavículas de cadáveres foram avaliadas por três observadores distintos, aplicando-se o escore de congruência da clavícula e comparando quatro sistemas diferentes de placas bloqueadas anatômicas pré-moldadas de seis a oito furos. Resultados: a concordância interobservador foi considerada moderada pelo percentual de concordância e regular pelo índice Kappa de Fleiss, sem diferenças significativas entre as avaliações. Apenas uma das oito placas apresentou encaixe anatômico maior que 70%. As placas longas (oito furos) apresentaram um encaixe ruim em comparação com as placas curtas (seis ou sete furos). Conclusões: os sistemas de placa superior pré-moldadas disponíveis atualmente fornecem um encaixe inadequado às clavículas para fixações de fraturas do terço médio. Placas longas apresentam um encaixe pior que as curtas.

Morphometric study of the c6 and c7 pedicle: a computerized tomography analysis / Estudo morfométrico do pedículo de c6 e c7: uma análise por tomografia computadorizada / Estudio morfométrico del pedículo c6 y c7: análisis por tomografía computarizada

ABSTRACT Objective: Measure the diameter and thickness of the C6 and C7 pedicles using computed tomography, to analyze the security of the act surgery and the difference between males and females. Methods: This is a retrospective study. Two hundred computerized tomography scans of the cervical spine, one hundred male and one hundred female, from the Hospital Santa Teresa Radiology sector were evaluated. The pedicle thickness was measured in the axial plane, and the height was measured in sagittal slices. The student's t-test was used to compare differences between the sexes, and a p-value lower than 0.05 was considered significant. Results: The mean age of the individuals included in the sample was 35±9 years. The mean height of the C6 and C7 pedicles were 7.1±0.9 mm and 7.8±0.9 mm, respectively. The mean thickness of the C6 and C7 pedicles were 5.2±0.7 mm and 5.9±0.8 mm, respectively. The statistical test showed that the values were significantly lower for female patients. Conclusions: The present study demonstrated parameters that can be used and can be the rule for preoperative planning of transpedicular cervical fixation surgeries, both in C6 and C7. As it is a procedure that can cause iatrogenic damage to important structures, the screw size must be chosen with care in pre-operative planning to avoid vessel rupture or damage to adjacent nerves. Level of Evidence III; retrospective study.

Correlation between low back pain due to fatty degeneration and sex and age: study by mri / Correlação entre lombalgia por degeneração gordurosa e sexo e idade: estudo por irm / Correlación entre el dolor lumbar por degeneración grasa y el sexo y la edad: estudio por irm

ABSTRACT Objective: To correlate low back pain caused by fatty degeneration, visualized by magnetic resonance imaging (MRI), with sex and age. Methods: With a timeframe of 2015 to 2020, data on sex and age of fifty symptomatic patients with low back pain were collected from medical records and correlated with MRI analyses showing the occurrence of fatty infiltration in the paraspinal and erector muscles. Three trained observers, using the classification of Goutallier et al. (1994), analyzed five lumbar levels and the degree of injury. The Kolmogorov-Smirnov, Shapiro Wilk, Student's t, Mann-Whitney and Spearman correlation tests were used, all with a 5% significance level. Results: Among the cases, the L5-S1 level was found in all the images, with a prevalence of 46% of grades 1 and 2 and 24% in the five lumbar levels. Severity was present in a small portion (8%) of the injuries. There was a predominance of 78% women, with significantly more severe injuries in relation to the number of levels (p < 0.001) and injuries of a higher degree (p < 0.001). The age range was 14 to 38 years (mean = 26.70 ± 5.70 years), showing a significant and moderate correlation between the number of levels reached and a greater degree of degeneration (p < 0.001). Conclusion: Fatty degeneration as a cause of low back pain was significantly more severe in women in terms to the number of levels and the higher degree of injury. The number of levels and the severity of fatty degeneration were not correlated with the patient's age. Level of evidence II; Retrospective Study.

Infection after primary total knee arthroplasty: a randomized controlled prospective study of the addition of antibiotics to bone cement.

Objective The present prospective, randomized and controlled study was conducted with 286 patients submitted to primary total knee arthroplasty (TKA) with the objective of evaluating the efficacy of the addition of antibiotics to bone cement as a way to prevent post arthroplasty infection (PAI). Methods The patients were randomized into two groups: bone cement without antibiotic (No ATB, n = 158) or cement with antibiotic (ATB, n = 128), in which 2 g of vancomycin was added to 40 g of cement. The patients were followed up for 24 months after surgery. Results Regarding preoperative demographic data, the distribution of patients between groups was homogeneous ( p < 0.05). In the 24-month period, the overall infection rate was of 2.09% (6/286), with no difference (odds ratio [OR] = 1.636; 95% confidence interval [CI]: 0.294-9.080; p = 0.694) between the ATB group (1.56%; 2/128) and the No ATB group (2.53%; 4/158). In the No ATB group, the infection was caused by methicillin-resistant Staphylococcus aureus (MRSA) ( n = 2), methicillin-sensitive S. aureus (MSSA) ( n = 1) and Eschirichia coli ( n = 1). Proteus mirabilis and MSSA were isolated from patients in the ATB group. Among the comorbidities, all patients with PAI were hypertensive and nondiabetic. Two rheumatoid arthritis patients who developed PAI were from the ATB group. Conclusion The use of cement with ATB reduced the absolute number of infections, but without statistical difference between the groups; thus, routine use should not be encouraged.

Protocol of BRICS: Brazilian multicentric pragmatic randomised trial of surgical interventions for displaced diaphyseal clavicle fracture study: MIPO versus ORIF for the treatment of displaced midshaft clavicle fractures.

INTRODUCTION: Fractures of the diaphysis of the clavicle are common; however, treatment guidelines for this condition are lacking. Surgery is associated with a lower risk of non-union and better functional outcomes but a higher risk of complications. Open reduction and internal fixation with plates and screws are the most commonly performed techniques, but they are associated with paraesthesia in the areas of incisions, extensive surgical exposure and high rates of implant removal. Minimally invasive techniques for treating these fractures have a lower rate of complications. The aim of this study is to evaluate which surgical treatment option (minimally invasive osteosynthesis or open reduction and internal fixation) has better prognosis in terms of complications and reoperations. METHODS AND ANALYSIS: The study proposed is a multicentric, pragmatic, randomised, open-label, superiority clinical trial between minimally invasive osteosynthesis and open reduction and internal fixation for surgical treatment of patients with displaced fractures of the clavicle shaft. In the proposed study, 190 individuals with displaced midshaft clavicle fractures, who require surgery as treatment, will be randomised. The assessment will occur at 2, 6, 12, 24 and 48 weeks, respectively. The primary outcome of the study will be the number of complications and reoperations. For sample size calculation, a moderate effective size between the techniques was considered in a two-tailed test, with 95% confidence and 90% power. Complications include cases of infection, hypertrophic scarring, non-union, refracture, implant failure, hypoesthesia, skin irritation and shoulder pain. Reoperations are defined as the number of surgeries for pseudoarthrosis, implant failure, infection and elective removal of the implant. ETHICS AND DISSEMINATION: Study approved by the institutional ethics committee (number 34249120.9.0000.5505-V.3). The results will be disseminated by publications in peer-reviewed journals and presentations in medical meetings. TRIAL REGISTRATION NUMBER: RBR-3czz68)/UTN U1111-1257-8953.

Estimated exposure of spine surgeons to radiation / Estimativa da exposição de cirurgiões de coluna vertebral à radiação / Estimativa de la exposición de cirujanos de columna vertebral a la radiación

ABSTRACT Objective To estimate the amount of radiation received and accumulated in the bodies of two surgeons, one being the responsible surgeon and the other the assistant, performing spine surgery procedures over a period of 25 years. Methods Seventy-two spinal surgeries were performed during a seven-month period and the radiation loads were measured in both surgeons. The measurement of radiation was captured in fluoroscopy in anteroposterior and lateral incidences. The surgeon and the assistant used two dosimeters, one in the cervical region protecting the thyroid and the other on the lead apron in the genital region. The radioactive loads were measured in millisieverts and the accumulated charges were recorded monthly in both regions of the body in the two surgeons for seven months and the means for the work periods (1, 5, 10, 15, 20 and 25 years) were estimated. Results It was observed that in the surgeon the average accumulated radiation loads were 131.9% and 176.92% higher than those of the assistant in the cervical and genital regions, respectively. Conclusion While the use of X-rays is indispensable in routine orthopedic surgery, we have to consider the development of techniques of protection, rigor and discipline in the use of safety materials for surgeons. Preventive exposure reduction measures such as using thyroid protection equipment and turning the head away from the patient during fluoroscopy, among others, should be mandatory to promote less radiation exposure.

RESUMO Objetivo Estimar a quantidade de radiação recebida e acumulada no corpo de dois cirurgiões, durante período de 25 anos de trabalho, sendo um o cirurgião responsável e outro, assistente, nos procedimentos de cirurgia da coluna vertebral. Métodos Foram realizadas 72 cirurgias de coluna vertebral em um período de sete meses, e as cargas de radiação foram medidas nos dois cirurgiões. A medição da radiação foi captada em fluoroscópio nas incidências anteroposterior e de perfil. O cirurgião e o auxiliar utilizaram dois dosímetros, sendo um na região cervical protegendo a tireoide e outro sobre o avental de chumbo, na região genital. As cargas radioativas foram medidas em milisievert e as cargas acumuladas foram registradas mensalmente em ambas as regiões do corpo nos dois cirurgiões, durante sete meses, foram estimadas as médias no período (1, 5, 10, 15, 20 e 25 anos) de trabalho. Resultados Observou-se que no cirurgião as médias das cargas de radiação acumulada foram 131,9% e 176,92% superiores às do assistente nas regiões cervical e genital, respectivamente. Conclusão Enquanto o uso dos raios X for indispensável na rotina da cirurgia ortopédica, há de se considerar o desenvolvimento de técnicas de proteção, rigor e disciplina no uso materiais de segurança para os cirurgiões. Medidas preventivas de redução da exposição, como uso de equipamento para proteção da tireoide e girar a cabeça para se afastar do paciente durante a fluoroscopia, entre outras, devem ser obrigatórias para promover menor exposição à radiação. Nível de evidência II; Estudo prospectivo comparativo.

Methods Longitudinal, observational study with 32 consecutive patients (31 males; mean age, 41 years old) with comminuted midshaft clavicle fracture who were surgically treated using the minimally invasive osteosynthesis technique with a 3.5mm reconstruction plate in the upper position. Patients were clinically and radiologically evaluated for a minimum follow-up period of 12 months. Results In 30 patients (93.72%), fracture consolidation occurred in an average time of 17 weeks (range, 12 to 24 weeks). The mean follow-up time was 21 months (range, 12 to 45 months). No implant break or pseudoarthrosis were recorded. There was no complaint of paresthesia around the surgical incisions. The surgically-treated shoulder presented lower passive elevation and longer clavicle length (p < 0.05) compared with the contralateral shoulder. Functional evaluation revealed an average Disability of Arm, Shoulder and Hand (DASH) score of 1.75, which is considered satisfactory. Age > 60 years old had a negative correlation with DASH score (p <0.05). Conclusion The minimally invasive osteosynthesis technique was satisfactory for the treatment of comminuted midshaft clavicle fracture, with a high consolidation rate and a low complication rate.

Resumo Objetivo Avaliar os resultados funcionais e radiográficos do tratamento cirúrgico realizado em um grupo de pacientes com fratura multifragmentada da diáfise de clavícula, pela técnica minimamente invasiva, em seguimento mínimo de 12 meses. Métodos Estudo observacional longitudinal de 32 pacientes consecutivos (31 do sexo masculino, idade média 41 anos) com fratura multifragmentada da diáfise da clavícula tratados cirurgicamente pela técnica minimamente invasiva de osteossíntese com placa de reconstrução de 3,5 mm na posição superior, avaliados clínica e radiologicamente, com seguimento mínimo de 1 ano Resultados Resultados Trinta pacientes (93,72%) evoluíram com consolidação da fratura em tempo médio de 17 semanas (entre 12 e 24 semanas).

Idade >60 anos apresentou correlação negativa com escore DASH (p< 0,05). Conclusão A técnica minimamente invasiva de osteossíntese mostrou-se satisfatória para o tratamento da fratura multifragmentada da diáfise da clavícula, com elevada taxa de consolidação e baixo índice de complicações.

Septic Arthritis of the Pubic Symphysis in Adult: A Case Report.

Septic arthritis of the pubic symphysis is a rare condition. Risk factors include trauma, low-grade infection, urological or gynecological procedures, malignant tumors of the pelvis, sports, and intravenous drug abuse. This report describes a case of septic arthritis of the pubic symphysis in a 23-year-old male patient with no history of pelvic surgery, previous infections, or intense physical activity. Arthritis was diagnosed by blood culture positive for Enterococcus spp. and yeasts, and the patient was treated with antibiotics. This case emphasizes the importance of complementary exams to aid the treatment of septic arthritis of the pubic symphysis and shows that an invasive procedure, such as pubic symphysis puncture biopsy, may not be required.

Current challenges and controversies in the management of scapular fractures: a review.

Fractures of the scapula are rare and usually associated with high-energy trauma. The unfavorable scapular anatomy, combined with the complexity of the approaches for fracture fixation, make the treatment challenging, even for experienced surgeons. Furthermore, the literature is controversial regarding surgical indications and rationale for treatment. The present review article was designed to address and discuss critical aspects of decision-making for the management of scapular fractures, including surgical indications and patient safety considerations.

The hidden risk of ionizing radiation in the operating room: a survey among 258 orthopaedic surgeons in Brazil.

BACKGROUND: This study aims to assess orthopaedic surgeon knowledge in Brazil about ionizing radiation and its health implications on surgical teams and patients. METHODS: A 15-question survey on theoretical and practical concepts of ionizing radiation was administered during the 23rd Brazilian Orthopaedic Trauma Association annual meeting. The survey addressed issues within orthopedic surgery, such as radiation safety concepts, protection, exposure, as well as the participant gender. Participants were either orthopedic surgeons or orthopedic surgery residents working at institutions in Brazil. RESULTS: One thousand surveys were distributed at the moment of the meeting registration, and 258 were answered completely (25.8% response rate). Only 5.8% of participants used basic radiation protection equipment; 47.3% used a dosimeter; 2.7% reached the annual maximum permissible radiation dose; 10.5% knew the period of increased risk to fetal gestation; 5.8% knew the maximum permissible radiation dose during pregnancy; 58.5% knew that the hands, eyes, and thyroid are the most exposed areas and at greater risk of radiation-related lesions; 25.2% knew the safe distance from a radiation-emitting tube is 3 m or more; 44.2% knew the safest positioning of the radiation-emitting tube; 25.2% knew that smaller tubes emit greater radiation at the entrance dose to magnify the image; and 55.4% knew that the surgery team receives more scattered radiation in surgical procedures performed on obese patients. CONCLUSION: This study revealed inadequate theoretical and practical knowledge about radiation exposure among orthopaedic surgeons in Brazil. Only a minority of orthopaedic surgeons used basic radiation protection equipment. No significant differences in knowledge were found when comparing all orthopedic surgery specialties. Our findings indicate an urgent need for education to increase knowledge among orthopaedic surgeons about the hazards of ionizing radiation. Personal protection and implementation of the ALARA (as low as reasonably achievable) protocol in daily practice are important behaviors to prevent the harmful effects of ionizing radiation.

Positioning Technique of the Fixed Knee in Hyperflexion for the Transportal Femoral Tunnel During Reconstruction of the Anterior Cruciate Ligament.

During reconstruction surgery of the anterior cruciate ligament, the evolution of the femoral tunnel from the transtibial to the transportal path provides greater accuracy in reaching the desired anatomic point. However, there are also some new challenges, such as correct execution, reproducibility, and minimizing the risk of iatrogenic injury from its use. In an effort to overcome these challenges, we have proposed the use of a positioner, which was developed by our group and allows the leg to stay in the desired position, without variations in the operation or aid from a medical assistant. This manuscript presents our femoral tunnel preparation technique and its application in clinical practice.

Functional and Radiological Outcomes of the Surgical Treatment of Acute Acromioclavicular Dislocation with Anchors Associated with Clavicle and Scapula Fixation / Resultados funcionais e radiológicos do tratamento cirúrgico da luxação acromioclavicular aguda com âncoras e fixação clavículo-escapular

Abstract Objective To evaluate the clinical, radiological and functional results of the surgical treatment of acute acromioclavicular dislocation using a coracoclavicular fixation technique (syndesmopexy) with two metallic anchors, temporary clavicle and scapula fixation, and transfer of the coracoacromial ligament. Methods Longitudinal observational study of 30 patients with diagnoses of acute acromioclavicular dislocation, who were submitted to surgical treatment with a minimum follow-up of six months, and who were evaluated clinically, radiologically, and by the University of California at Los Angeles (UCLA), the Disabilities of the Arm, Shoulder and Hand (DASH) and the Constant-Murley functional scores. Results The mean values of the scores were: UCLA = 32; DASH = 11.21; and Constant-Murley = 86.93, with satisfactory results higher than 80%. The unsatisfactory results were associated with acromioclavicular pain on palpation, positive subacromial impingement tests, and older age group, presenting statistical significance (p < 0.05). Radiologically, higher values on account of the coracoclavicular distance ratio from the operated shoulder compared to the normal shoulder were related to worse outcomes, but with no statistically significant difference. No associations were found between the results of the functional scores and the variables degree of the injury, coracoacromial ligament transfer, clinical impression of loss of reduction and scapulothoracic dyskinesis. Conclusion The technique used provides an efficient fixation, with a high level of satisfaction according to the UCLA, Constant-Murley and DASH scores; moreover, it has a low complication rate, despite the high rate of residual radiological acromioclavicular subluxation.

Resumo Objetivo Avaliar os resultados clínicos, radiológicos, e funcionais do tratamento cirúrgico da luxação acromioclavicular aguda, utilizando a técnica de sindesmopexia coracoclavicular com duas âncoras metálicas, fixação temporária clavículo-escapular, e transferência do ligamento coracoacromial. Métodos Estudo observacional longitudinal com trinta pacientes com diagnóstico de luxação acromioclavicular aguda submetidos à cirurgia, com seguimento mínimo de seis meses, avaliados clínica, radiograficamente, e pelos escores de University of California at Los Angeles (UCLA), Disabilities of the Arm, Shoulder and Hand (DASH) e Constant-Murley. Resultados Os valores médios dos escores foram: UCLA = 32; DASH = 11,21; e Constant-Murley = 86,93, com resultados satisfatórios acima de 80%. Os resultados insatisfatórios foram relacionados à dor acromioclavicular, a testes de impacto subacromial positivos, e aos pacientes de faixa etária mais elevada (p < 0,05). Radiologicamente, valores maiores em razão da distância coracoclavicular do ombro operado, comparado com o ombro normal, foram relacionados a piores resultados, embora sem significância estatística. Não foi observada associação entre os resultados dos escores funcionais e as variáveis grau da lesão, transferência do ligamento coracoacromial, impressão clínica de perda de redução, e discinesia escapulo-torácica. Conclusão A técnica utilizada propicia uma fixação eficiente, com alto índice de satisfação segundo os escores de UCLA, Constant-Murley e DASH. Observou-se baixo índice de complicações apesar da frequência elevada de subluxação acromioclavicular radiológica residual.

Böhler's Angle-Comparison Between the pre- and Postoperative in Displaced Intra-Articular Calcaneal Fractures.

Objective To compare pre- and postoperative variation of radiographic measurements of the Böhler angle (BA) in fractures with two types of deviations: severe and moderate. Methods Pre- and postoperative BAs in 31 calcaneal fracture radiographs were retrospectively analyzed. A total of 4 patients were female (6.5%) and 26 were male (83.9%), with age ranging from 23 to 72 years old, and a mean age of 44.5 years old. Results The results show that the postoperative BA was significantly larger than the preoperative BA ( p = 0.000). At the intraevaluator and overall assessments, the postoperative BA was, on average, 10.6° higher than the preoperative measure. The postoperative angle was, on average, 108% higher than the preoperative angle. In the global assessment, the agreement between evaluators was excellent, both regarding the estimated point value (0.98) and the intraclass correlation (ICC) confidence interval (CI). Conclusion In the global analysis, the postoperative BAs were, on average, significantly higher than the preoperative measurements. The farther from the normal range (20° to 40°) the preoperative angle is, the greater the difference after the surgery. When the preoperative angle was normal, the postoperative angle was, on average, 1.28 times the preoperative measurement. If the preoperative BA was abnormal, the postoperative angle was, on average, 17.3 times the preoperative measurement. It was demonstrated that more severe fractures present better anatomic results when compared with moderate fractures. The present study also confirms a good interobserver correlation for the BA.

Proximal Femur Fracture and Vascular Injury in Adults-Case Report.

Vascular complications in the surgical treatment of hip fractures are rare. Depending on the arterial injury, severe intraoperative bleeding or a subacute hematoma formation with arterial pseudoaneurysm development can occur. In the literature, the more frequently described complications are large local hematomas after osteosynthesis with sliding hip screws. This report shows a case of delayed arterial injury after proximal femur osteosynthesis.
