RESUMO
BACKGROUND: Hip fractures resulting from falls increase substantially with advancing age and less than half of older hip fracture survivors regain their former levels of mobility. There is increasing evidence that rehabilitation interventions with exercises that goes beyond the sub-acute phase or even in a later stage of care have a positive impact on various functional abilities. The purpose of this study is to determine if exercise program training for people who have suffered a fall-related hip fracture will improve functional mobility when compared with usual care. METHODS: A randomized controlled trial with blinded assessors and intention-to-treat analysis will be undertaken. We will recruit 82 older adults, 60 years or over who have suffered a hip fracture due to a fall in the previous 6 to 24 months. Participants randomized to the Intervention Group (IG) will undertake a physical exercise program involving progressive and challenging balance training and neuromuscular and functional training of the lower limbs, conducted at home by physiotherapists, once a week, lasting about one hour, in the first, second and third month after randomization and will be taught to perform exercises at home, twice a week, using a booklet. Visits to monitor and progress the home exercise program will be conducted once a month, from the fourth to the sixth month and each 2 months until the end of the follow up at the 12th month, i.e., a total of 18 sessions. Participants will receive monthly phone calls to encourage exercise adherence. The control group will receive usual care. The primary outcome will be mobility-related disability and participants will be assessed at baseline, and at 3 months, 6 and 12 months. Participants will receive monthly phone calls to ask about falls and exercise adherence. Adverse effects will be monitored. DISCUSSION: This study proposes a home-based exercise program, which may in part overcome some barriers for rehabilitation, such as difficulties with public transportation and lack of a caregiver to accompany older patients to sessions. If a positive effect is observed this program has the potential to be incorporated into the public health system and contribute to building a pathway of care for older people with hip fracture.

Objective: Identify the predictors associated with delayed union at 6 months and non-union at 12 months in tibial shaft fractures treated with intramedullary nailing (IMN). Methods: This retrospective longitudinal study included a cohort of 218 patients who sustained tibial shaft fractures and received IMN between January 2015 and March 2022. We gathered data on a range of risk factors, including patient demographics, trauma intensity, associated injuries, fracture characteristics, soft tissue injuries, comorbidities, addictions, and treatment-specific factors. We employed logistic bivariate regression analysis to explore the factors predictive of delayed union and non-union. Results: At the 6-month follow-up, the incidence of delayed union was 28.9%. Predictors for delayed union included flap coverage, high-energy trauma, open fractures, the use of external fixation as a staged treatment, the percentage of cortical contact in simple type fractures, RUST score, and postoperative infection. After 12 months, the non-union rate was 15.6%. Conclusion: the main predictors for non-union after IMN of tibial shaft fractures are related to the trauma energy. Furthermore, the initial treatment involving external fixation and postoperative infection also correlated with non-union. Level of Evidence III; Retrospective Longitudinal Study.

RESUMO
The widespread adoption of smartphones and other mobile devices amongst healthcare providers opened new possibilities arising from the use of non-medical apps, social media, meeting platforms, and non-medical devices with intended medical purposes, thus expanding the communication and imaging chat systems between these professionals and their patients, as well as amongst healthcare professionals. However, adapting non-medical applications, social media, videoconference platforms and devices for medical use present potential limitations, barriers, and risks, which should be fully recognized to reduce crossing the fine line between ethical and unethical. In the herein study, we analyse the ethical limits, coverage, and validation of non-medical applications adapted for medical use. Level of evidence: IV (evidence from well-designed case-control or cohort studies).

INTRODUCTION: Hip fracture in elderly individuals is frequent and is related to a high rate of mortality. Finding the best predictor of death will help to develop better patient care. Aim - To analyze the reliability of the clinical data and assessment scores to predict mortality in acute hip fracture in elderly patients. PATIENT AND METHODS: Prospective data were collected from all patients > 65 years with acute hip fracture from May to October 2020. The clinical data collected were age, sex, comorbidities, medication, type of fracture and presence of delirium. The assessment scores were ASA, Lee, ACP and Charlson. RESULTS: The statistically significant results were age > 80 years (OR 1.121 IC95% [1.028-1.221] p = 0.0101) and number of medications (OR5.991 95% CI [2.422-14.823] p <0.001). Three scores showed a correlation with mortality: ASA score (p = 0.017), Lee score (p = 0.024) and ACP score (p = 0.013). The Charlson Comorbidity Index did not correlate with mortality (p = 0.172). CONCLUSION: To stratify the risk of death, both clinical data and scores should be used. The best clinical indicators are age and number of medications, and the scores are ASA, Lee and ACP.

RESUMO
Introduction: Tibial shaft fracture is the most common long-bone fracture, and the standard treatment is intramedullary (IM) nail fixation. Regardless of the development of this technique pseudoarthrosis remains prevalent. Objectives: Evaluate the correlation between wedge fragment size and displacement, displacement of the main fragments of the 42B2 type, and pseudoarthrosis incidence. Methods: We retrospectively assessed all patients with 42B2 type fracture treated with IM nailing between January, 2015 and December, 2019. Six radiographic parameters were defined for preoperative radiographs in the anteroposterior (AP) and lateral views. Another six parameters were defined for postoperative radiographs at three, six, and 12 months. The Radiographic Union Score for Tibial Fractures score was used to assess bone healing. Results: Of 355 patients with tibial shaft fractures, 51 were included in the study. There were 41 (82.0%) male patients, with a mean age of 36.7 years, 37 (72.5%) had open fractures, and 28 (54.9%) had associated injuries. After statistical analysis, the factors that correlated significantly with nonunion were wedge height > 18 mm, preoperative translational displacement of the fracture in the AP view > 18 mm, and final distance of the wedge in relation to its original anatomical position after IM nailing > 5 mm. Conclusion: Risk factors for nonunion related to the wedge and42B2 fracture are wedge height > 18 mm, initial translation in the AP view of the fracture > 18 mm, and distance > 5 mm of the wedge from its anatomical position after IM nailing.

Introdução: A fratura da diáfise da tíbia é a fratura mais comum dentre os ossos longos, sendo o tratamento padrão a fixação com haste intramedular (HIM). Independentemente do desenvolvimento da técnica cirúrgica, a pseudoartrose continua prevalente. Objetivo: Avaliar a associação entre o tamanho e o desvio da cunha, os desvios dos fragmentos principais do tipo 42B2 e a incidência de pseudoartrose. Métodos: Avaliamos, retrospectivamente, todos os pacientes com fraturas tipo 42B2 tratados com hastes intramedulares entre janeiro de 2015 e dezembro de 2019. Seis parâmetros radiográficos foram definidos para as radiografias pré-operatórias nas incidências anteroposterior (AP) e perfil. Outros seis parâmetros foram definidos para as radiografias pós-operatórias em 3, 6 e 12 meses de acompanhamento pós-operatório. O Escore Radiográfico de União para as Fraturas da Tíbia (RUST) foi o instrumento usado para avaliar a consolidação óssea. Resultados: Dos 355 pacientes com fraturas da diáfise da tíbia, 51 foram incluídos no estudo. Os pacientes incluídos foram 41 (82,0%) do sexo masculino, com idade média de 36,7 anos, 37 (72,5%) com fraturas expostas e 28 (54,9%) com lesões associadas. Após análise estatística, os fatores que se correlacionaram significativamente com a não consolidação foram a altura da cunha > 18 mm, o deslocamento translacional pré-operatório da fratura na incidência AP > 18 mm e a distância final da cunha em relação à sua posição anatômica original após a cravação do MI > 5 mm. Conclusão: Os fatores de risco para a pseudartrose relacionada com a fratura em cunha e42B2 são a altura da cunha > 18 mm, a translação inicial na vista AP da fratura > 18 mm e a distância > 5 mm da cunha em relação à sua posição anatómica após a fixação IM.

RESUMO
BACKGROUND: About 10% of ankle fractures are located above the syndesmosis, which causes injury to the ligament structure of the syndesmosis. There is no consensus regarding when to allow weight-bearing on the operated limb of patients who suffered ankle fractures requiring intraoperative fixation. OBJECTIVE: The aim of this study is the evaluation of radiographic parameters of syndesmosis reduction and fixation in patients with ankle fracture who underwent immediate protected weight-bearing (use of walking-boot and crutches). PATIENT AND METHODS: Retrospective case series from January 2015 to December 2020. Evaluation of the tibiofibular clear space, tibiofibular overlap, and medial clear space in the preoperative x-ray, immediate postoperative, 3-, 6- and 12-month after syndesmosis fixation and rehabilitation with protected immediate weight-bearing with crutches and walking-boot. RESULTS: Out of 137 ankle fractures 39 were included. There was no significant difference in the tibiofibular clear space between the immediate x-ray and after 12 months (4.5 mm ± 1.1 vs. 4.6 mm ± 1.8; p > 0.999). Tibiofibular overlap hasn't shown significant difference between immediate and 12-month x-ray (6.2 mm ± 2.6 vs. 6.6 mm ± 2.6; p > 0.999). Medial clear space also has shown no worsening from immediate to 12-month x-ray (3.1 mm ± 0.9 vs. 2.8 mm ± 0.9; p > 0.999). There were no fixation failure nor postoperative infection. CONCLUSION: Immediate weight-bearing for patients with ankle fractures with syndesmosis injury and treated with intraoperative fixation with positioning screw proved to be safe with good maintenance of the reduction, no failures of the synthesis material observed and no reports of postoperative infection in the period. LEVEL 3 EVIDENCE: therapeutic retrospective case-series.

This study aims to evaluate the effectiveness of an online course to enable orthopaedic surgeons to acquire the core competencies necessary to prevent and treat fracture-related infections (FRI). This study included orthopaedic surgeons and residents from Latin American countries who attended an online course focused on FRI. The online course included: didactic lectures, small-group clinical case discussions, and panel case discussions. The course was delivered using Zoom® platform and designed to address four core competencies: prevention, definition and diagnosis, antimicrobial therapy, and surgical treatment. An online questionnaire was created distributing 16 questions through six clinical scenarios. Participants were invited to answer the questionnaire before and after the course. Sixty of the 78 course participants answered the pre-course, and 42 the post-course assessment. Relative to before the course, the mean post-course assessment score rose significantly for prevention of FRI (4.1 before and 4.5 after; p = 0.014), definition and diagnosis (2.4 before and 3.4 after; p = 0.001), and surgical treatment (2.2 before and 2.8 after; p = 0.011). The final score encompassing all four core competencies also rose significantly (2.7 before and 3.3 after; p = 0.001). The online course on FRI was feasible and effective, significantly increasing course users' knowledge of overall competency in managing FRI.
RESUMO
Objective: evaluate the functional treatment outcome of deviated transverse olecranon fractures (Mayo 2A) after treatment with tension-banded intramedullary screw (PIBT) compared to classical tension band (BTC). Methods: Prospectively collect all deviated transverse olecranon fractures from 2012 to 2016 and randomize them into PIBT and BTC groups. Range of motion (ROM) was measured after 2 and 5 weeks, 3 and 6 months, and 1 and 2 years. Functional assessments (DASH, Oxford Elbow Score, and Mayo Elbow Performance Index) were performed after 3 and 6 months and 1 and 2 years. Complications were collected up to 2 years of follow-up. Results: 22 patients were included, 11 in each group. The mean age was 47.9 years, and the left side was injured in 13 (59.0%) patients. All patients completed the 2-year follow-up. There was no ROM difference at any time between the two groups (p> 0.005). Flexion and extension gain was maximum at three months and remained unchanged until two years. Neither flexion nor extension returned to normal, missing around 10°. Pronation and supination returned to normal. All three functional scores showed almost complete recovery of elbow function after three months postoperatively, with no difference between the groups. No group had complications, no reoperation, and no implant removal. Conclusion: PIBT had similar results in ROM and functional score compared to BTC. Both had low complication rates and no need for implant removal. Level of evidence I; Randomized Trial .
Objetivo: Avaliar o resultado funcional do tratamento das fraturas transversas desviadas do olécrano (Mayo 2A) após o tratamento com parafuso intramedular com banda de tensão (PIBT) em comparação com a banda de tensão clássica (BTC). Métodos: Foram coletados prospectivamente todas as fraturas transversas do olécrano desviadas de 2012 a 2016 e randomizá-las em dois grupos: PIBT e BTC. A amplitude de movimento (ADM) foi medida após 2 e 5 semanas, 3 e 6 meses e 1 e 2 anos. As avaliações funcionais (DASH, Oxford Elbow Score e Mayo Elbow Performance Index) foram realizadas após 3 e 6 meses e 1 e 2 anos. As complicações foram coletadas até 2 anos de acompanhamento. Resultados: Foram incluídos 22 pacientes, 11 em cada grupo. A idade média foi de 47,9 anos, e o lado esquerdo foi lesado em 13 (59,0%) pacientes. Todos os pacientes completaram o acompanhamento de 2 anos. Não houve diferença na ADM em nenhum momento entre os dois grupos (p> 0,005). O ganho de flexão e extensão foi máximo aos 3 meses e permaneceu inalterado até 2 anos. Nem a flexão nem a extensão voltaram ao normal, faltando em torno de 10º. A pronação e a supinação voltaram ao normal. Todos os três escores funcionais mostraram uma recuperação quase completa da função do cotovelo após 3 meses de pós-operatório, sem diferença entre os grupos. Nenhum grupo apresentou complicações, nem reoperação ou retirada do implante. Conclusão: O PIBT teve resultados semelhantes na ADM e pontuação funcional em comparação com o BTC. Ambos tiveram baixas taxas de complicações e não há necessidade de remover implantes. Nível de evidência I; Estudo clínico randomizado.
RESUMO
Objective: Radiographically evaluate the quality of reduction over six weeks of follow-up in patients with surgically treated deviated acetabular fractures who underwent rehabilitation with immediate loading as tolerated and compare this with the results of the unloaded protocol. Methods: We retrospectively evaluated the records of 137 patients with deviated acetabular fractures treated with open reduction and internal fixation. Sixty-six (48.2%) patients underwent postoperative rehabilitation with immediate loading as tolerated, while 71 (51.8%) patients completed rehabilitation using a no-load protocol. The quality of the reduction was assessed radiographically by measuring the fracturing step and gap on radiographs taken immediately after surgery and three and six weeks after surgery. Results: Comparing the joint step, group 1 had an average of 0.44 ± 1.4 mm, 0.47 ± 1.5 mm, and 0.51 ± 1.6 mm immediately, three and six weeks after surgery, respectively. Group 2 had a mean step of 0.24 ± 0.8 mm, 0.27 ± 0.9 mm, and 0.37 ± 1.2 mm immediately, three, and six weeks after surgery. No statistically significant differences were observed between the groups. With a joint gap, group 1 had a mean of 1.89 ± 1.7 mm, 2.12 ± 1.8 mm, and 2.36 ± 2.1 mm; and group 2 had a mean of 2.16 ± 2.4 mm, 2.47 ± 2.6 mm, and 2.67 ± 2.8 mm in the immediate postoperative period, three, and six weeks, respectively. There was also no statistical difference between groups in these measurements. Conclusion: Immediate loading after surgical treatment of deviated acetabular fracture had no negative impact on radiographic reduction parameters and had similar results to the protocol without weight bearing. Level of evidence III; Therapeutic Retrospective Cohort Study .
Objetivo: Avaliar radiograficamente a qualidade da redução ao longo de 6 semanas de acompanhamento em pacientes com fratura desviada do acetábulo tratados cirurgicamente e submetidos à reabilitação com carga imediata conforme tolerado e comparar com os resultados do protocolo sem carga. Métodos: Avaliamos retrospectivamente os prontuários de 137 pacientes com fraturas desviadas do acetábulo que foram tratadas com redução aberta e fixação interna. Sessenta e seis (48,2%) pacientes foram submetidos à reabilitação pós-operatória com carga imediata conforme tolerado, enquanto 71 (51,8%) pacientes completaram a reabilitação utilizando um protocolo sem carga. A qualidade da redução foi avaliada radiograficamente pela medição do degrau da fratura e do gap nas radiografias feitas imediatamente após a cirurgia e três e seis semanas após a cirurgia. Resultados: Comparando o degrau articular, o grupo 1 teve uma média de 0,44 ± 1,4 mm, 0,47 ± 1,5 mm e 0,51 ± 1,6 mm imediatamente, três e seis semanas após a cirurgia, respectivamente. O grupo 2 teve um degrau médio de 0,24 ± 0,8 mm, 0,27 ± 0,9 mm e 0,37 ± 1,2 mm imediatamente, três e seis semanas após a cirurgia. Não foram observadas diferenças estatísticas significantes entre os grupos. Com gap articular, o grupo 1 teve uma média de 1,89 ± 1,7 mm, 2,12 ± 1,8 mm e 2,36 ± 2,1 mm; e o grupo 2 de 2,16 ± 2,4 mm, 2,47 ± 2,6 mm e 2,67 ± 2,8 mm nos pós-operatório imediato, três e seis semanas, respectivamente. Também não houve diferença estatística entre os grupos nessas medidas. Conclusão: A carga imediata após o tratamento cirúrgico da fratura do acetábulo desviada não teve impacto negativo nos parâmetros de redução radiográfica e teve resultados semelhantes em comparação com o protocolo sem descarga de peso.

RESUMO
Objectives To describe the functional result of the conservative treatment of displaced proximal humerus fractures (PHF) using the American Shoulder and Elbow Surgeons (ASES) score after 12 months and assess whether the different initial classifications and radiographic measurements are related to clinical results. Methods Forty patients > 60 years old, with displaced PHUs submitted to conservative treatment were evaluated at standardized times (3, 6, and 12 months). The American Society of Shoulder and Elbow Surgeons (ASES), Constant-Murley and Single Assessment Numeric Evaluation (SANE) scales were used as clinical outcomes. Radiographic variables included the Neer and Resch classifications, the presence and displacement of tuberosity fracture, metaphyseal comminution, medial periosteal lesion, and angular and translational deviations of the head in the coronal and sagittal plane. Results The result of the ASES score was 77.7 ± 23.2 for the whole sample, the mean absolute values of the Constant-Murley score were 68.7 ± 16 and 82.6% for the scale relative to the contralateral side. The SANE scale at 12 months was 84.8 ± 19. We observed that the severity of the Neer classification and the coronal plane angular deviation (measured by the head-shaft angle) and the presence of fractures in both tuberosities negatively influenced the ASES score after 12 months of treatment. Conclusion Nonoperative treatment of displaced proximal humerus fractures in elderly patients results in good clinical results. Clinical results are negatively influenced by the angular deviation of the humeral head and the presence of fractures of the greater and lesser tubercles, as well as by the Neer classification.
RESUMO
Objective: To assess the complications in patients with severe slipped capital femoral epiphysis treated with the Dunn or modified Dunn procedure from 2012 to 2018 at the Institute of Orthopedics and Traumatology, Medical School, Universidade de São Paulo. Methods: Analysis of medical records, preoperative and postoperative radiographs with at least one year of radiographic follow-up of patients with severe slipped capital femoral epiphysis. Results: We reviewed the complications in 19 operated cases from 2012 to 2018, out of which 36.8% had osteonecrosis of the femoral head, one patient had chondrolysis, and another had postoperative infection. Conclusion: The osteonecrosis rate observed in this series of cases is similar to that described in other orthopedic facilities. We assessed factors that could potentially influence this outcome, including other characteristics of the patient (obesity, endocrine diseases, and history of sports activities) and of the health system.

RESUMO
Objective: Determine complications' incidence and risk factors in high-energy distal femur fractures fixed with a lateral locked plate. Methods: Forty-seven patients were included; 87.2% were male, and the average age was 38.9. The main radiographic parameters collected were distal lateral femoral angle (DFA), distal posterior femoral angle (DPLF), comminution length, plate length, screw working length, bone loss, and medial contact after reduction and plate-bone contact, location of callus formation, and implant failure. The complications recorded were nonunion, implant failure, and infection. Results: Complex C2 and C3 fractures accounted for 85.1% of cases. Open fractures accounted for 63.8% of cases. The mean AFDL and AFDP were 79.8 4.0 and 79.3 6.0, respectively. The average total proximal and distal working lengths were 133.3 42.7, 60.4 33.4, and 29.5 21.8 mm, respectively. The infection rate was 29.8%, and the only risk factor was open fracture (p = 0.005). The nonunion rate was 19.1%, with longer working length (p = 0.035) and higher PDFA (p = 0.001) as risk factors. The site of callus formation also influenced pseudoarthrosis (p = 0.034). Conclusion: High-energy distal femoral fractures have a higher incidence of pseudoarthrosis and infection. Nonunion has greater working length, greater AFDL, and absence of callus formation on the medial and posterior sides as risk factors. The risk factor for infection was an open fracture.

As complicações registradas foram não união, falha do implante e infecção. Resultados: Fraturas complexas C2 e C3 representaram 85,1% dos casos. As fraturas expostas corresponderam a 63,8% dos casos. O AFDL e AFDP médios foram 79,8° ± 4,0° e 79,3°± 6,0°, respectivamente. Os comprimentos de trabalho total, proximal e distal médios foram 133,3 ± 42,7, 60,4 ± 33,4 e 29,5 ± 21,8 mm, respectivamente. A taxa de infecção foi de 29,8% e o único fator de risco foi a fratura exposta (p = 0,005). A taxa de não união foi de 19,1%, com maior comprimento de trabalho (p = 0,035) e maior PDFA (p = 0,001) como fatores de risco. O local de formação do calo também influenciou na pseudoartrose (p = 0,034). Conclusões: Fraturas distais do fêmur de alta energia apresentam maior incidência de pseudoartrose e infecção. A não união tem como fatores de risco maior comprimento de trabalho, maior AFDL e ausência de formação de calo nos lados medial e posterior. O fator de risco para infecção foi a fratura exposta.

RESUMO
INTRODUCTION: Acetabular fractures are among the most complex orthopedic injuries, and their treatment and understanding have evolved remarkably in the last 50 years. Several factors affect the reduction quality of the surgically treated displaced acetabular fractures. Thus, this study aimed to identify these factors by analyzing patients' data. PATIENTS AND METHODS: Retrospective data from fractures operated in one center over 8 years were analyzed. Patients with a mature skeleton who underwent open reduction and internal fixation and had a minimum follow-up period of 6 weeks were included. Non-displaced fractures were excluded from the study. Radiographic assessment of the reduction was performed before surgery and at follow-up using the method described by Borelli et al. The effects of age (<40 or >40 years), sex, initial displacement (< 20 mm or > 20 mm), time to surgery (<14 days or>14 days), fracture pattern (elementary or associated), number of associated fractures (< 3 or > 3), and associated pelvic injury were analyzed RESULTS: The study included 115 (83.9%) men and 22 (16.1%) women, with a mean age of 34.1 years (range 16-74 years). In the sixth week of follow-up, reductions were satisfactory in 96 (70.7%) patients and unsatisfactory in 41 (29.3%). The most prevalent patterns were the posterior wall (23.1%) and both column (15.7%). Linear regression showed that residual displacement was directly correlated with initial displacement (p = 0.027) but without association with reduction quality. Age, sex, and initial displacement had no effect on reduction quality, which is in contrast with longer time to surgery (p = 0.004), associated fracture pattern (p = 0.002), three or more associated fractures (p = 0.001), and presence of associated pelvic injury (p = 0.021). CONCLUSION: Attempting to shorten the time to operate the fractures can lead to better results for patients because the other factors associated with poor reduction are inherent the trauma and cannot be modified by the surgeon.

INTRODUCTION: open tibial fractures are challenging due to the frequent severe bone injury associated with poor soft tissue conditions. This is relevant in low- and middle-income countries, mainly related to delayed definitive fixation and lack of adequate training in soft tissue coverage procedures. Due to these factors, open tibial fracture is an important source of disability for Latin American countries. Herein we sought to provide an epidemiological overview of isolated open tibial shaft fracture across seven hospitals in southern cone of Latin America. The secondary goal was to assess the impact on quality of life based on return-to-work rate (RWR). METHODS: patients with an isolated open tibial shaft fracture treated in seven different hospitals from Brazil and Argentina from November 2017 to March 2020 were included in the study. Clinical and radiographic results were evaluated throughout the 120-day follow-up period. Final evaluation compared RWR with the SF-12 questionnaire, bone healing, and gait status. RESULTS: Seventy-two patients were treated, 57 followed for 120 days and 48 completed the SF-12 questionnaire. After 120 days, 70.6% had returned to work, 61.4% had experienced bone healing. Age, antibiotic therapy, type of definitive treatment, and infection significantly influenced the RWR. Gait status exhibited strong correlations with RWR and SF-12 physical component score. CONCLUSIONS: Isolated open tibial shaft fractures are potentially harmful to the patient's quality of life after 120 days of the initial management. RWR is significantly higher for younger patients, no history of infection, and those who could run in the gait status assessment.

Femoral Shaft intramedullary nails were first described by the Aztecs in 16th century, but the modern use of intramedullary nails as the gold standard treatment for femoral shaft fractures began with Gerald Kuntcher in 1939. From the first Kuntcher's study in 1939, to the creation of interlocking nail, a long and some minor developments were described around the world. However, a major development is missing: the first nail to have a rotational and vertical stability locking system was described by Flavio Godoy Moreira, but was never published on an indexed journal for the correct historical reference.

A história da haste intramedular bloqueada nas fraturas do fêmur se inicia com os Astecas no século 16, mas o uso moderno que a tornou o padrão ouro no tratamento destas fraturas se inicia com Gerald Kuntcher em 1939. Do estudo inicial de Kutcher até o desenvolvimento da haste bloqueada muitos pequenos desenvolvimentos foram descritos ao redor do mundo. Dentro deste desenvolvimento, a primeira haste a ter um controle vertical e rotacional foi descrito por Flavio Pires de Camargo, e nunca foi publicado em um jornal indexado que permita sua correta referência histórica.

RESUMO
Translational deformities are common complications of conservatively managed bone fractures and some surgically managed fractures with unstable patterns. Realigning the bones can be difficult when soft tissue, scars and calluses form. These deformities can be easily corrected with hexapodalic-based external fixators, but these fixators are not widely available in developing countries. We describe a stable and reliable Ilizarov frame that can be used to treat these deformities and show results of clinical cases.

INTRODUCTION: Forearm shaft fracture is common in young adult patients and associated with soft tissue and organ injuries. In open fractures in polytrauma patients, damage control orthopaedics (DCO) is well indicated. The aim of this study is to describe intramedullary Steinmann pin fixation of the ulna as a DCO procedure for the forearm and present a case series. DESCRIPTION OF THE TECHNIQUE: A 3.0 mm Steinmann pin is inserted retrograde in the ulna proximal fragment through the fracture site using the open wound as the approach. With direct visualization of the reduction, the pin is advanced into the distal fragment. The reduction of the longitudinal axis and shortening is thus achieved. PATIENTS AND METHODS: This method was used for all open fractures of forearm both-bone fractures in polytrauma patients undergoing DCO from 2014 to 2019. The alignment and length of the ulna were evaluated radiographically after pin fixation and before and after definitive fixation. Differences in the need for secondary procedures and infection rate between DCO and definitive fixation were also evaluated. RESULTS: There were 30 males (85.7%) with an average age of 32.9 ± 12.0 years and a mean ISS (Injury Severity Score) of 29.4 (range, 18.0-41.0). The most common associated injuries were thoracic trauma (62.8%) and head trauma (45.7%). In the radius and ulna, 51.4% and 60.0% of fractures, respectively, were multifragmentary (types B and C). Gustilo type IIIA represented 77.1% of the injuries. Pin fixation achieved good alignment and length in all cases. The mean time between DCO and definitive fixation was 12.0 days, and no secondary procedure was needed, nor any case developed either superficial or deep infection. The conversion from DCO to definitive fixation was considered easy in all cases. CONCLUSION: Intramedullary Steinmann pin fixation of the ulna is a viable option for DCO for forearm both-bone fractures in open fractures in polytrauma patients.

INTRODUCTION: Non-operative treatment is an exceptional indication for the treatment of proximal femur fracture. The aim of the study was to analyze the mortality rate in one year and associated factors in severely ill patients submitted to non-operative treatment. METHODS: It was included 28 patients treated from August 2014 to September 2019. Eighteen (64.3%) patients were female and 10 (35.7%) were male. The mean age was 78.7 ± 11.9 years old. The main outcome evaluated was the mortality rate in one year. It was also evaluated the correlation with gender, age, personal habits, number of comorbidities and Charlson Comorbidity Index (CCI). RESULTS: The functional result was assessed with WOMAC score via telephone call. The mortality rate in one year was 42.8% without statistical positive correlation with any of the studied parameters. Patients with three or more comorbidities didn't have a higher mortality rate comparing to survived patients (83.3% vs 81.3%). The CCI also didn't show any correlation with high mortality (6.9 vs 7.1). The functional result of the survived patients was poor (78.2 points WOMAC). CONCLUSION: The conclusion is that the mortality rate in one year of ill patients with hip fractures treated non-operatively is 42.8% without correlation with age, gender of number of comorbidities, and the functional result of the survived patients is poor.
