Computed tomography evaluation before the operation is the gold standard(3). Given the great difficulty in making pre and intraoperative evaluations on this fragment, there has been much study on this subject.
Studies on fractures of the distal region of the radius with long follow-ups have correlated the functional result with maintenance of the anatomical parameters, and have cited that one of the factors giving a poor prognosis is modification of the joint congruence, in which joint steps of 1 or 2 mm would lead to symptomatic arthrosis in a large percentage of the patients(2). This lesion pattern results from axial loads, which cause the semilunar to collide with its fossa, thereby fragmenting it, and this is known as a diepunch fracture. The semilunar fossa is a common component in radial fractures, and may be the only component affected. With greater exposure to high-energy trauma in large cities, and increasing life expectancy among the population, the number of intra-articular fractures has increased in the same proportion(1). CEP 02404-001 E-mail: for publication:, accepted for publication: įractures of the distal extremity of the radius account for approximately a sixth of the fracture of the human body.

Conclusão: A incidência tangencial foi superior na avaliação do degrau articular de 1mm e 3mm e a segunda melhor quando houve degrau de 2mm e 5mm.Descritores - Clavícula Pseudoartrose Anormalidades Congênitas.ġ - Assistant physician of the Hand Surgery and Microsurgery Group, Irmandade da Santa Casa de Misericórdia de São Paulo - São Paulo, SP, Brazil.Ģ - Resident physician of the orthopedics and traumatology service of the Irmandade da Santa Casa de Misericórdia de São Paulo - São Paulo, SP, Brazil.ģ - Resident physician of the orthopedics and traumatology service of the Irmandade da Santa Casa de Misericórdia de São Paulo - São Paulo, SP, Brazil.Ĥ - Doctor and Head of the Hand Surgery and Microsurgery Group, Irmandade da Santa Casa de Misericórdia de São Paulo - São Paulo, SP, Brazil.ĥ - Doctor and Senior Consoultant of the Hand Surgery and Microsurgery Group, Irmandade da Santa Casa de Misericórdia de São Paulo - São Paulo, SP, Brazil. No desvio de 2mm a melhor incidência foi a oblíqua semipronada e no de 5mm a oblíqua semissupinada, sendo que não se consegue identificar os desvios de 1 e 2mm na oblíqua semissupinada. Resultados: A incidência tangencial foi a melhor para identificar os desvios de 1 e 3mm e a segunda melhor nos desvios de 2 e 5mm.

Em uma segunda etapa, avaliou-se o desvio da fratura em cada radiografia, com auxílio do software AutoCAD 2010®. A peça foi submetida a radiografias nas incidências frente, perfil, oblíqua semipronada, oblíqua semissupinada e tangencial (75º com o plano da mesa). Fixou-se o fragmento distal com fita adesiva, nos degraus articulares de 1, 2, 3 e 5mm. Após limpeza e retirada de partes moles, realizou-se osteotomia da região dorsoulnar da superfície articular com microsserra, osteótomo e martelo.
Métodos: Utilizou-se um rádio do Banco de Tecidos Salvador Arena. Objetivo: Avaliar qual a melhor incidência radiográfica para diagnosticar os desvios da fratura tipo die-punch da extremidade distal do rádio. Keywords - Radius Fractures/radiography Radius Fractures/ surgery Cadaver The pronated oblique view was the best to see the 2mm degrees and the oblique supinated view wasn't able to see the degrees between 1 and 2mm.Conclusion: The tangencial view was the best one to see the 1mm and 3mm bone degrees and the second one view to see the 2mm and 5 mm degrees. Results: The tangencial view was the best one to see the 1mm and 3mm bone degrees and the second one view to see the 2mm and 5 mm degrees. The resulting lunate fossa depression in each X-ray film was analyzed by the AutoCAD 2010® software. Radiographs were then taken into 5 different positions: postero-anterior view, lateral view, oblique views and tangencial view for each of the deviations. Then the joint deviation were significantly increased with step-offs of 1 mm. We have fixed this fragment with adhesive tape.
This bone was cleaned up after removing the soft tissues and osteotomies created displaced lunate fossa fractures of 0, 1, 2, 3 and 5 mm. Methods: There has been used a human cadaver radius bone from the Salvador Arena Tissue Bank. ABSTRACTS Objective: the aim of this study is try to show the best view for distal radius fractures so called die-punch fractures.
