ABSTRACT
ABSTRACT The distal leg joint fractures are among the most common fractures in humans across all age groups, and 50% of them require surgical treatment. Few studies discuss the epidemiology and costs of this fracture in the global and national literature. Objective: To evaluate the annual incidence and reimbursement value of distal leg joint fractures requiring surgical treatment from 2008 to 2021. Methods: A retrospective study was conducted to analyze the complex structured data of high volume and high variability (Big Data), publicly available on the TabNet platform (DATASUS), via software with artificial intelligence. Data from 2008 to 2021 on surgical treatment for malleolar fracture, distal tibia fracture, and isolated fibula fracture were analyzed. Results: From 2008 to 2021, there was an average incidence of 28.8 fractures/105 inhabitants per year, representing 14.62% of all fractures. The total amount paid for hospitalizations due to these fractures was R$ 34,218,014.62 over these 14 years. Conclusion: The incidence of distal leg joint fractures follows the pattern of those recorded in other countries. The adjustment of reimbursement over the years was lower than the accumulated inflation. Level of Evidence II, Economic and Decision Analyses - Developing an Economic or Decision Model.
RESUMO As fraturas articulares distais da perna estão entre as fraturas mais comuns do ser humano ao longo de todas as faixas etárias, e 50% delas necessitam de tratamento cirúrgico. Existem poucos trabalhos discutindo a epidemiologia e os custos dessa fratura na literatura mundial e, principalmente, na nacional. Objetivo: Avaliar a incidência anual e o valor de reembolso das fraturas distais da perna com indicação para tratamento cirúrgico entre os anos de 2008 e 2021. Métodos: Estudo retrospectivo para analisar os dados complexos estruturados de alto volume e alta variabilidade (Big Data), disponibilizados publicamente na plataforma TabNet (Datasus), através de um software com inteligência artificial. Foram analisados os dados de 2008 a 2021 do tratamento cirúrgico de fratura maleolar, fratura distal da tíbia e fratura isolada da fíbula. Resultados: Entre 2008 e 2021, houve incidência média de 28,8 fraturas/105 habitantes-ano, representando 14,62% de todas as fraturas. O valor total pago pelas internações dessas fraturas foi de R$ 34.218.014,62 ao longo desses 14 anos. Conclusão: A incidência das fraturas articulares distais da perna acompanha o padrão daqueles registrados em outros países. O reajuste do repasse ao longo dos anos foi inferior à inflação acumulada.

ABSTRACT
ABSTRACT Objective The magnetic resonance imaging diagnostic criteria for a complete tear of metatarsophalangeal plantar plate are well-established. However, more subtle abnormalities can also occur and be a source of pain. The objective of this study is to determine the prevalence of degenerative plantar plate injuries in patients with metatarsalgia who underwent forefoot magnetic resonance imaging and describe the main abnormalities found. The hypothesis is that mild capsular fibrosis will have high sensitivity but low specificity for plantar plate degenerative injuries. Methods A retrospective cross-sectional study was conducted with 85 patients (105 feet) with metatarsalgia who underwent forefoot magnetic resonance imaging using a specific protocol to study metatarsophalangeal plantar plate. The experiment observer classified second toe plantar plate as normal, complete rupture or degenerative lesion and described the main magnetic resonance imaging findings. Results A normal plantar plate was observed in 75 (71.4%) of the 105 feet assessed, in 25 (24%) feet there were degenerative plantar lesions, and in 5 (4.6%) feet there were complete ruptures. Degenerative injury of the plantar plate was best identified in coronal short axis intermediate-weighted images, with high sensitivity (92%). Pericapsular fibrosis below the intermetatarsal ligament was identified in 96% of cases, with high sensitivity (96%) for diagnosis of degenerative plantar plate injury. Conclusion Degenerative lesions of the metatarsophalangeal plantar plate were more prevalent than complete ruptures and were best viewed in coronal short axis intermediate-weighted sequences. Pericapsular fibrosis below the intermetatarsal ligament was the indirect finding most strongly associated with degenerative plantar plate injury.
ABSTRACT
To find the best clinical parameters for defining and classifying the degree of plantar plate injuries. METHOD: Sixty-eight patients (100 metatarsophalangeal joints) were classified in accordance with the Arthroscopic Anatomical Classification for plantar plate injuries and were divided into five groups (0 to IV). Their medical files were reviewed and the incidence of each parameter for the respective group was correlated. These parameters were: use of high heels, sports, acute pain, local edema, Mulder's sign, widening of the interdigital space, pain in the head of the corresponding metatarsal, touching the ground, "drawer test", toe grip and toe deformities (in the sagittal, coronal and transversal planes). RESULTS: There were no statistically significant associations between the degree of injury and use of high-heel shoes, sports trauma, pain at the head of the metatarsal, Mulder's sign, deformity in pronation or displacement in the transversal and sagittal planes (although their combination, i.e. "cross toe", showed a statistically significant correlation). Positive correlations with the severity of the injuries were found in relation to initial acute pain, progressive widening of the interdigital space, loss of "touching the ground", positive results from the "drawer test" on the metatarsophalangeal joint, diminished grip strength and toe deformity in supination. CONCLUSIONS: The "drawer test" was seen to be the more reliable and precise tool for classifying the degree of plantar plate injury, followed by "touching the ground" and rotational deformities. It is possible to improve the precision of the diagnosis and the predictions of the anatomical classification for plantar plate injuries through combining the clinical history and data from the physical examination.
Encontrar os melhores parâmetros clínicos para definir e classificar o grau das lesões da placa plantar. MÉTODO: Foram classificados 68 pacientes (100 articulações metatarsofalângicas [MTF]) de acordo com a classificação anatômica artroscópica para lesão de placa plantar e divididos em cinco grupos (0 a IV). Seus registros médicos foram revisados e se correlacionou a incidência de cada parâmetro no respectivo grupo. Os parâmetros foram: uso de saltos altos, esportes, dor aguda, edema local, sinal de Mulder, alargamento do espaço interdigital, dor na cabeça do metatarso correspondente, toque ao solo, "teste da gaveta", preensão dos dedos e deformidades dos dedos (plano sagital, coronal e transversal). RESULTADOS: Não houve associação estatisticamente significativa entre o grau de lesão e o uso de sapatos de salto alto, trauma esportivo, dor de cabeça do metatarso, sinal de Mulder, deformidade em pronação, desvio no plano transversal e sagital (embora a sua combinação, o crossover toe, tenha mostrado correlação estatisticamente significativa). A correlação positiva com a severidade das lesões foi encontrada em: dor aguda no início, alargamento progressivo do espaço interdigital, perda de "toque ao solo"; positividade do "teste de gaveta" da MTF; diminuição da força de preensão e deformidade em supinação do dedo. CONCLUSÕES: O "teste de gaveta" se apresenta como a ferramenta mais confiável e precisa para classificar o grau da lesão da placa plantar, seguido pelo "toque ao solo" e as deformidades rotacionais. É possível melhorar a precisão do diagnóstico, bem como a previsão da classificação anatômica de lesão da placa plantar, por meio da combinação de história clínica e de dados de exame físico.
