EVALUATION OF THE EPIDEMIOLOGY OF EXPOSED FRACTURES BEFORE AND DURING THE COVID-19 PANDEMIC.

Objective: To assess the impact of the COVID-19 pandemic on the epidemiology and clinical outcomes of open fractures considering the periods before and during the pandemic. Methods: An observational and retrospective study, which included patients aged over 18 years, admitted to the Orthopedics and Traumatology Ward of Hospital São Paulo, of the Federal University of São Paulo (UNIFESP). Data was collected in two moments: pre-pandemic (March 1, 2019, to February 29, 2020) and during the pandemic (March 1, 2020, to February 28, 2021). Results: In total, 183 patients were evaluated with a mean age of 36 years ± 14 years. In the pre-pandemic period, 94 patients underwent surgery, 81 men (85.37%) and 13 women (14.2%), with a mean age of 36 ± 3 years. During the pandemic period, 89 patients were subjected to surgery, 77 men (86.6%) and 12 women (13.4%), with a mean age of 38 ± 3 years. Conclusion: During the pandemic, open fractures were still more common in men. Regarding hospital indicators, the prevalence of infections in the surgical wound and the length of stay of patients with open fractures increased, however, with little significance. Fractures classified as Gustilo IIIA were the most common, while the most common according to the AO classification were 33, 34, 42, 43, 2R3, and 2R3 + 2U2. The frequency of run overs during the pandemic decreased. However, firearm projectile injuries and falls and occupational injuries increased. Level of Evidence III, Retrospective Comparative Study.

Métodos: Estudo observacional e retrospectivo que incluiu pacientes maiores de 18 anos, internados na Enfermaria de Ortopedia e Traumatologia do Hospital São Paulo, da Universidade Federal de São Paulo. Os dados foram coletados em dois momentos - antes (março de 2019 a fevereiro de 2020) e durante a pandemia (março de 2020 a fevereiro de 2021) -, por meio da análise de prontuários eletrônicos de todos os registros hospitalares dessa instituição. Resultados: No total, foram avaliados 183 pacientes com média de idade de 36 ± 14 anos. No período pré-pandêmico, foram operados 94 pacientes, sendo 81 homens (85,37%) e 13 mulheres (14,2%), com média de idade de 36 ± 3 anos. Já ao longo do período pandêmico, foram operados 89 pacientes, sendo 77 homens (86,6%) e 12 mulheres (13,4%), com média de idade de 38 ± 3 anos. Conclusão: Durante a pandemia, a ocorrência de fraturas expostas se manteve com maior frequência em indivíduos do sexo masculino. Quanto aos indicadores hospitalares, houve aumento da prevalência de infecções na ferida operatória, assim como do tempo de internação dos pacientes, todavia, com pouca significância. Foram mais frequentes as fraturas classificadas como Gustilo IIIA e, pela classificação AO, as fraturas 33, 34, 42, 43, 2R3 e 2R3 + 2U2. Notamos redução da frequência de atropelamentos durante a pandemia e aumento dos casos de ferimentos por projétil de arma de fogo, quedas e acidentes ocupacionais.

FACTORS ASSOCIATED WITH THE OUTCOMES OF OLDER PATIENTS OPERATED DUE TO HIP FRACTURES.

Objective: Evaluating clinical factors associated with mortality in older patients who underwent surgical correction of hip fractures. Methods: This observational and retrospective study analyzed the medical records of 67 patients (aged older than 60 years), both men and women, who underwent surgical correction of hip fractures from 2019 to 2020 at Hospital São Paulo. The following variables were analyzed: age, sex, presence of comorbidities, affected hip region, and trauma mechanism. Statistical analyses were performed using the SPSS software. Results: The mean age of patients was 78.12 ± 9.80 years and 80.6% of the sample were women. The prevalence of hip fractures on the right side (52.2%), in the transtrochanteric region (53.7%), and due to fall on the same level (88.1%) was higher. Systemic arterial hypertension (77.6%), diabetes mellitus (37.3%), and dementia (16.4%) were frequent comorbidities. The prevalence of death after fracture was 17.9% and it was associated with longer hospital stay after surgery (p = 0.028). Conclusion: The prevalence of mortality of patients with hip fractures who underwent surgery was 17.9%. A longer hospital stay due to pre-existing comorbidities was the main factor related to this outcome. Level of Evidence III, Retrospective Study.

FRAGILITY FRACTURES IN BRAZIL: CROSS-SECTION STUDY.

Objective: To evaluate the involvement of orthopedists and orthopedic residents with fragility fractures, in its clinical, therapeutic, and social aspects. Methods: Cross-sectional observational and prospective study that took place in the period from June to August 2020. Results: 540 participants were analyzed. The population consisted of orthopedists (85.56%; N = 462) and residents (14.44%; N = 78), with a greater proportion of individuals from 41 to 50 years of age (36.67%; N = 198) and from the Southeast region (57.22%; N = 309). For 47.04% (N = 254) of the participants, the profile of the patient at risk for fragility fracture corresponds to: woman, sedentary, smoker and over 60 years of age. The consensus among the participants (97.96%; N = 529) is that fragility fractures occur in or near home environments. Moreover, 47.59% (N = 257) believe that the first fragility fracture is the most important predictive risk factor for subsequent occurrences and 63.89% (N = 345) of the participants claim to attend more than 15 cases per year. Regarding treatment, 74.44% (N = 402) are dedicated exclusively to orthopedic aspects (68.33%; N = 369). However, 62.41% (N = 337) of the participants believe that patients with fragility fractures should receive medication and supplements. Likewise, 70.74% (N = 382) of the participants consider that home security measures and training of family members are important, and they attribute the role to the multidisciplinary team. Conclusions: Fragility fractures are frequent in the routine of Brazilian orthopedists. However, they are not familiar with adjuvant treatments for fragility fractures, acting almost exclusively in the orthopedics aspects of these injuries. Level of Evidence II, Prospective Study.

Para 47,04% (N = 254) dos participantes o perfil do paciente em risco para fratura por fragilidade corresponde a: mulher, sedentária, tabagista e acima dos 60 anos de idade. Sendo consenso entre os participantes (97,96%; N = 529) que as fraturas por fragilidade ocorrem em ambientes domiciliares ou próximo a eles. Além disso, 47,59% (N = 257) dos participantes acreditam que a primeira fratura por fragilidade seja o fator de risco preditivo mais importante para novo episódio de fratura e 63,89% (N = 345) dos avaliadores atendem mais de 15 casos por ano. Em relação ao tratamento, 74,44% (N = 402) dedicam-se exclusivamente aos aspectos ortopédicos (68,33%; N = 369). No entanto, 62,41% (N = 337) dos participantes acreditam que paciente devam receber medicamentos e suplementos. Da mesma forma, 70,74% (N = 382) dos avaliadores consideram que medidas de segurança domiciliar e treinamento de familiares sejam importantes e atribuídas a equipe multiprofissional. Conclusão: As fraturas por fragilidade são frequentes na rotina dos ortopedistas brasileiros. No entanto, estes não estão familiarizados com tratamentos adjuvantes nas fraturas consideradas por fragilidade, atuando quase que exclusivamente nos aspectos ortopédicos envolvidos nestas lesões.

Three-dimensional printing models increase inter-rater agreement for classification and treatment of proximal humerus fractures.

BACKGROUND: Proximal humerus fractures (PHF) are frequent, however, several studies show low inter-rater agreement in the diagnosis and treatment of these injuries. Differences are usually related to the experience of the evaluators and/or the diagnostic methods used. This study was designed to investigate the hypothesis that shoulder surgeons and diagnostic imaging specialists using 3D printing models and shoulder CT scans in assessing proximal humerus fractures. METHODS: We obtained 75 tomographic exams of PHF to print three-dimensional models. After, two shoulder surgeons and two specialists in musculoskeletal imaging diagnostics analyzed CT scans and 3D models according to the Neer and AO/OTA group classification and suggested a treatment recommendation for each fracture based on the two diagnostic methods. RESULTS: The classification agreement for PHF using 3D printing models among the 4 specialists was moderate (global k = 0.470 and 0.544, respectively for AO/OTA and Neer classification) and higher than the CT classification agreement (global k = 0.436 and 0.464, respectively for AO/OTA and Neer). The inter-rater agreement between the two shoulder surgeons were substantial. For the AO/OTA classification, the inter-rater agreement using 3D printing models was higher (k = 0.700) than observed for CT (k = 0.631). For Neer classification,  inter-rater agreement with 3D models was similarly higher (k = 0.784) than CT images (k = 0.620). On the other hand, the inter-rater agreement between the two specialists in diagnostic imaging was moderate. In the AO/OTA classification, the agreement using CT was higher (k = 0.532) than using 3D printing models (k = 0.443), while for Neer classification, the agreement was similar for both 3D models (k = 0.478) and CT images (k = 0.421). Finally, the inter-rater agreement in the treatment of PHF by the 2 surgeons was higher for both classifications using 3D printing models (AO/OTA-k = 0.818 for 3D models and k = 0.537 for CT images). For Neer classification, we saw k = 0.727 for 3D printing models and k = 0.651 for CT images. CONCLUSION: The insights from this diagnostic pilot study imply that for shoulder surgeons, 3D printing models improved the diagnostic agreement, especially the treatment indication for PHF compared to CT for both AO/OTA and Neer classifications On the other hand, for specialists in diagnostic imaging, the use of 3D printing models was similar to CT scans for diagnostic agreement using both classifications.

ABSTRACT Objective: To evaluate the conduct of Brazilian orthopedists regarding preventive treatment after fragility fracture surgery. Methods: A questionnaire was applied to Brazilian orthopedists. Statistical analyses were performed using the SPSS 16.0 program. Results: 257 participants were analyzed. Most participants, 90.7% (n = 233), reported that they cared for patients with fractures and 62.3% (n = 160) treated them. The most indicated treatments were vitamin D (22.6%; n = 134) and calcium supplementation (21.4%; n = 127). According to the experience of the physicians - experienced (n = 184) and residents (n = 73) - fragility fractures were more common in the routine of residents (98.6%; n = 72) than experienced physicians (87.5%; n = 161), p = 0.0115. While treatment conduction was more reported by experienced physicians (63.6%; n = 117) than residents (58.9%; n = 43), p = 0.004. More experienced orthopedists (21.4%; n = 97) indicated treatment with bisphosphates than residents (14.2%; n = 20), p = 0.0266. Conclusion: Although most professionals prescribe treatment after fragility fracture surgery, about 40% of professionals still do not treat it, with differences in relation to experience. In this sense, we reinforce the importance of secondary prevention in the management of fragility fractures. Level of Evidence II, Prospective comparative study.

RESUMO Objetivo: Avaliar a conduta adotada por ortopedistas brasileiros em relação ao tratamento adjuvante após a cirurgia de fraturas de fragilidade. Métodos: Foi aplicado um questionário aos ortopedistas brasileiros. A estatística foi realizada no programa SPSS 16.0. Resultados: Foram analisados 257 participantes. A maioria dos participantes 90,7% (n = 233) relataram atender os pacientes com fraturas e 62,3% (n = 160) relataram tratar. Os tratamentos mais indicados foram a suplementação de vitamina D (22,6%; n = 134) e de cálcio (21,4%; n = 127). De acordo com a comparação médicos experientes (n = 184) versus médicos residentes (n = 73), a rotina de fraturas de fragilidade foi mais observada por médicos residentes (98,6%; n = 72) que por médicos experientes (87,5%; n = 161), p = 0,0115. Enquanto a conduta de tratamento foi mais relatada por médicos experientes (63,6%; n = 117) versus médicos residentes (58,9%; n = 43), p = 0,004. A maior proporção de médicos experientes (21,4%; n = 97) indicaram o tratamento com bifosfatos versus médicos residentes (14,2%; n = 20), p = 0,0266. Conclusão: Apesar da maioria dos profissionais prescreverem um tratamento após a cirurgia de fraturas de fragilidade, cerca de 40% dos profissionais ainda não tratam, sendo observadas diferenças em relação à experiência. Neste contexto, reforçamos a importância da prevenção secundária na conduta de fraturas de fragilidade. Nível de Evidência II, Estudo prospectivo comparativo.

Three-dimensional models increase the interobserver agreement for the treatment of proximal humerus fractures.

BACKGROUND: The agreement for the treatment of proximal humerus fractures is low. Interpretation of exams used for diagnosis can be directly associated with this limitation. This study proposes to compare the agreement between experts and residents in orthopedics for treatment indication of proximal humerus fractures, utilizing 3D-models, holography (augmented reality), x-rays, and tomography as diagnostic methods. METHODS: Twenty orthopedists (ten experts in shoulder and elbow surgery and ten experts in traumatology) and thirty resident physicians in orthopedics evaluated nine fractures of the proximal humerus, randomly distributed as x-rays, tomography, 3D-models and holography, using the Neer and AO / OTA Classifications. After, we evaluated the interobserver agreement between treatment options (conservative, osteosynthesis and arthroplasty) and whether the experience of the evaluators interfered with the results. RESULTS: The interobserver agreement analysis showed the following kappa-values: κ = 0.362 and κ = 0.306 for experts and residents (3D-models); κ = 0.240 and κ = 0.221 (X-ray); κ = 0.233 and κ = 0.123 (Tomography) and κ = 0.321 and κ = 0.160 (Holography), for experts and residents respectively. Moreover, residents and specialists were discordant in the treatment indication using Tomography as a diagnostic method (p = 0.003). The same was not seen for the other diagnostic methods (p > 0.05). CONCLUSIONS: Three-dimensional models showed, overall, the highest interobserver agreement (experts versus residents in orthopedics) for the choice of treatment of proximal humerus fractures compared to X-ray, Tomography, and Holography. Agreement in the choice of treatment among experts that used Tomography and Holography as diagnostic methods were two times higher compared to residents.

Inter-observer reliability of alternative diagnostic methods for proximal humerus fractures: a comparison between attending surgeons and orthopedic residents in training.

BACKGROUND: Proximal humerus fractures are frequent, and several studies show low diagnostic agreement among the observers, as well as an inaccurate classification of these lesions. The divergences are generally correlated with the experience of the surgeons as well as the diagnostic methods used. This paper challenges these problems including alternative diagnostic methods such as 3D models and augmented reality (holography) and including the observers' period of medical experience as a factor. METHODS: Twenty orthopedists (ten experts in shoulder surgery and ten experts in traumatology) and thirty resident physicians in orthopedics classified nine proximal humerus fractures randomly distributed as x-ray, tomographies, 3D models and holography, using AO/ASIF and Neer's classification. In the end, we evaluated the intra- and inter-observer agreement between diagnostic methods and whether the experience of the observers interfered in the evaluations and the classifications used. RESULTS: We found overall kappa coefficients ranging from 0.241 (fair) to 0.624 (substantial) between the two classifications (AO / ASIF and Neer), concerning the diagnostic methods used. We identified image modality differences (p = 0.017), where 3D models presented an average kappa coefficient value superior to that of tomographies. There were no differences between kappa scores for x-ray and holography compared to the others. The kappa scores for AO / ASIF classification and Neer classification and subdivided by observer period of experience showed no differences concerning the diagnostic method used. CONCLUSIONS: 3D models can substantially improve diagnostic agreement for proximal humerus fractures evaluation among experts or resident physicians. The holography showed good agreement between the experts and can be a similar option to x-ray and tomography in the evaluation and classification of these fractures. The observers' period of experience did not improve the diagnostic agreement between the image modalities studied. TRIAL REGISTRATION: Registered in the Brazil Platform under no. CAAE 88912318.1.0000.5487.

Quality of life after antegrade intramedullary nail fixation of humeral fractures: a survey in a selected cohort of Brazilian patients.

BACKGROUND: The treatment of humeral fractures remains controversial. Systematic reviews demonstrate similar results between dynamic compression plating and locked intramedullary nailing in the surgical treatment of these fractures. However, it appears that antegrade intramedullary nailing causes higher residual pain in the shoulder. The proposal of this work is to evaluate through the WORC protocol (Western Ontario Rotator Cuff Index) the consequences in the quality of life of patients submitted to osteosynthesis of the humerus with antegrade locked intramedullary nailing. METHODS: This work is a cohort retrospective study in addition to the application of a questionnaire for self-rated quality of life with its 05 domains (WORC - Western Ontario Rotator Cuff Index) for patients (N = 26) classified in the Trauma Sector of the Department of Orthopedics and Traumatology of the Federal University of São Paulo (DOT/UNIFESP) submitted to Humerus Osteosynthesis with Antegrade Locked Intramedullary Nailing. There was also the inclusion of data related to the time since surgery, age, sex, surgical laterality, dominance among members and work leave, which were not considered in the original protocol. After, the data were statistically assessed to evaluate the association between numerical and categorical variables. RESULTS: The overall WORC score was 82.75 ± 17.00 (Mean ± SD) and was not different considering sex, age and postoperative period. Among the WORC domains, both Work and Sport / Recreation Protocols were the most unfavorable factors in the evaluation of patients. Although not statistically significant, those who had the procedure on the dominant side presented a lower quality of life score than those who had the surgery on the non-dominant side. Although non-significant again, those who were away from work had an overall lower quality of life score than those who were not. CONCLUSIONS: The WORC Quality of Life Protocol shows good results for evaluating patients submitted to humerus osteosynthesis with antegrade locked intramedullary nailing. The data stratified by domains were good, however, Work and Sport/Recreation domains showed the lowest means compared to the other domains.

Trombose venosa da veia subclávia após fratura de clavícula: relato de caso / Subclavian vein thrombosis following fracture of the clavicle: case report

A trombose venosa profunda no membro superior não é frequente na literatura ortopédica. Relatamos um caso de trombose da veia subclávia durante o tratamento conservador de fratura do terço médio da clavícula. O diagnóstico é difícil e requer um alto grau de suspeição e o tratamento pode prevenir um tromboembolismo fatal. Há raros casos descritos associados à fratura de clavícula.

Deep vein thrombosis in the upper limbs is uncommon in the orthopedic literature. We report on a case of subclavian vein thrombosis that occurred during conservative treatment of a fracture in the middle third of the clavicle. This is difficult to diagnose and requires a high degree of suspicion. Treating it may prevent fatal thromboembolism. In some rare cases, it has been described in association with fractures of the clavicle.

Fixação das fraturas do platô tibial com placas pela via de acesso posterior - relato preliminar de 12 casos / Tibial plateau fractures fixation using posterior approaches - preliminary results of 12 cases

OBJETIVO: Apresentar os resultados preliminares com técnicas de abordagem posterior para fraturas do platô tibial, com traço de cisalhamento no plano sagital. MÉTODOS: Doze pacientes com fraturas do platô tibial tratados cirurgicamente através de um acesso posterior direto foram incluídos no estudo. Foram revisados os prontuários, as radiografias e tomografias dos pacientes bem como as avaliações clínicas. Todos os casos foram acompanhados até o momento da consolidação óssea, definido como aquele em que o paciente apresentava sinais radiográficos compatíveis sendo capaz de apoiar carga total sobre o membro sem referir dor. RESULTADOS: Entre julho de 2009 e abril de 2010, foram atendidos em nosso serviço 89 pacientes com fraturas da extremidade proximal da tíbia. Desses, 80 (89,9 por cento) foram tratados cirurgicamente. Doze pacientes (13,6 por cento) apresentavam uma fratura com um componente de cisalhamento posterior e, portanto, foram submetidos a abordagens posteriores para redução e fixação da fratura. Em três destes casos associou-se uma abordagem antero-lateral. A média de idades dos pacientes foi de 35 anos. O acompanhamento médio foi de 12 meses (entre 8 e 23 meses). As fraturas foram classificadas de acordo com o sistema AO/OTA: cinco como 41 B1, quatro como 41 B3, duas como 41 C1 e uma como 41 C3. Dentre as complicações, tivemos uma deiscência de sutura, tratada com curativos, e uma perda de redução que necessitou de uma reoperação. Em nenhum caso ocorreu lesão neurovascular, retarde de consolidação, pseudartrose ou instabilidade articular residual. Em 4 casos a redução foi considerada ruim (> 2mm de degrau articular), em 5 casos foi considerada imperfeita (< 2 mm de degrau articular) e em 3 casos obtivemos uma redução anatômica. CONCLUSÃO: Os autores concluem que o uso da abordagem posterior deve ser considerada em casos de fraturas com onde haja componente de cisalhamento posterior do planalto da tíbia. Uma casuística ampliada é necessária para avaliar o real benefício desta abordagem.

OBJECTIVE: To describe our preliminary results of posterior shearing tibia plateau fractures treated by a direct dorsal approach and plate fixation. METHODS: A consecutive series of twelve patients with tibia plateau fractures treated by direct posterior approach was selected from our database. Conventional radiographies, computed tomography scans and medical records were reviewed. All cases were followed to union, as defined by painless weight bearing and radiographic healing. RESULTS: Between July 2009 and April 2010, our trauma service received 89 tibia plateau fractures and treated 80 (89,9 percent) operatively. Twelve patients (13,5 percent) sustained posterior shearing tibia plateau fractures. All fractures were treated through the posterior approach, although 3 required association with an anterolateral approach as well. The mean age of patients was 35 years and mean follow-up was 12 (range 8-23) months. The fractures were classified according to AO/OTA: five 41 B1, four 41 B3, two 41 C1 and one 41 C3. There was one wound dehiscence, managed with local wound care, and one loss of reduction treated by reoperation. No patient sustained neurovascular injury, nonunion, malunions or knee instability. In four cases the reduction was rated as poor (> 2 mm step off), in five cases reduction was rated as imperfect (<2 mm step off) and in three cases the reduction was rated as anatomic (absolutely no step-off). CONCLUSION: Authors conclude that posterior approaches should be considered when tibial plateau fractures result in posterior displaced fragments. A larger sample is needed to get definitive conclusions.

Estudo transversal sobre o tratamento das lesões acrômioclaviculares agudas / Transversal study about acute acromioclavicular lesions

OBJETIVO: O objetivo do presente estudo transversal é verificar como o ortopedista brasileiro interpreta as lesões acromioclaviculares quanto aos critérios para a indicação do tratamento cirúrgico ou não, seus métodos preferidos, as complicações mais frequentes e os resultados obtidos. MÉTODOS: Durante o 6º Congresso Brasileiro de Cirurgia do Ombro e Cotovelo (CBOC) e o 38º Congresso Brasileiro de Ortopedia e Traumatologia (CBOT) foram distribuídos 507 questionários, sendo considerados 478 para análise. RESULTADOS: Em relação ao tratamento das LAC tipo I e II, a maioria dos entrevistados utilizam métodos não cirúrgicos. Em contraposição nas LAC IV, V e VI 475 (99,4 por cento) dos entrevistados tratam essas lesões cirurgicamente. Nas LAC tipo III não existe uma definição na escolha do tratamento cirúrgico ou não cirúrgico para 386 (80,7 por cento) entrevistados, sendo que o fator mais importante para tomada de decisão para a maioria dos entrevistados é a atividade esportiva do paciente e a idade. CONCLUSÃO: Nas LAC tipo III não há consenso, sendo o tratamento determinado conforme as características do paciente, contudo na literatura atual há uma tendência para o tratamento não cirúrgico destas lesões.

The objective of the present transversal study is to check how Brazilian orthopedists treat these injuries, their criteria for choosing the treatment, results and complications. METHODS: During the 6th Brazilian Congress of Shoulder and Elbow Surgery (CBOC) and the 38th Brazilian Congress of Orthopaedics and Traumatology (CBOT) 507 questionnaires were distributed (148 CBOC and 359 CBOT), with 478 being considered for analysis. RESULTS: Regarding type-I and -II ACIs, most of the respondents use traditional non-surgical methods. On the other hand, for type-IV, V and VI injuries, 475 (99.4 percent) of the respondents indicate surgical methods. Concerning type-III injuries, there is no consensus in the selection between traditional and surgical treatment for 386 (80.7 percent) respondents, with the most important factor for selecting a given treatment method being the patient's level of sports practice and age. CONCLUSION: There is no consensus regarding type-III ACIs, and the selection of the best treatment method is made according to patient's individual characteristics. However, current literature shows a trend towards non-operative methods.

Uso da placa onda no tratamento das fraturas diafisárias do fêmur não consolidadas / The wave plate method in non union femoral shaft fractures treatment

Estudou-se retrospectivamente 25 pacientes com fratura diafisária do fêmur não consolidadas e que foram tratados com placa onda. A consolidação ocorreu em 96 por cento dos pacientes num tempo médio de 5,32 meses, variando entre três e sete meses. Vinte e um pacientes (84 por cento) foram considerados como resultados excelentes e bons nos critérios de avaliação final. O método de tratamento não ocasionou diferença no comprimento dos membros. Não ocorreram desvios rotacionais. O arco de movimento dos quadris e joelhos não foi acometido, embora em quatro pacientes (16 por cento) tenha-se encontrado limitação na flexão do joelho, esta era prévia ao tratamento com placa onda. Dois pacientes (8 por cento) tiveram infecção profunda durante o tratamento com a placa onda, recidiva de processo infeccioso prévio. Houve soltura da placa no nono mês de pós-operatório em um paciente (4 por cento), embora tenha havido a consolidação óssea. Em outro paciente (4 por cento) a placa onda quebrou um ano e dois meses após a cirurgia, tendo-se trocado a primeira por outra placa onda e posterior consolidação. Mesmo assim, considerou-se falha do método. A placa onda é uma opção de tratamento das fraturas do fêmur não consolidadas pelas suas propriedades biomecânicas favoráveis à consolidação óssea, conferindo estabilidade sem prejudicar o suprimento sangüíneo, com características de síntese biológica.
