Distal radius fractures are an increasingly prevalent upper extremity injury, especially among elderly patients. They represent approximately 3% of all upper extremity injures. Severity of these fractures is directly related to bone mineral density of the patient, and clinical results are dependent on this parameter as well. There is a bimodal distribution of these injuries, with a peak between 18 to 25 years of age, predominantly male population and a second peak in the elderly, older than 65 years, predominantly female population. Early reports of fractures of the distal radius considered these fractures to be group of injuries with a relatively good prognosis irrespective of the treatment given. When it comes to complex fractures, regardless of the method applied, major or minor functional invalidity persists. With that in mind fractures of the distal radius are medical, social and economic problems of modern society.

“…Embora existam diversos sistemas de classificação das fraturas da extremidade distal do rádio, poucas incluem a "fratura de Barton". Fernandez (1993), em sua classificação, leva em consideração diferentes mecanismos que acarretam as fraturas do rádio, sendo as fraturas por cisalhamento classificadas como "tipo 2". Na classificação AO, Kreder et al (1996), as fraturas por cisalhamento são classificadas como "tipo B" (parcial articular), referindo-se as "B3" às fraturas de Barton.…”

Pinto Netto, H.B. Biomechanics of specific fixation system for ulnar volar corner of distal end of the radius. Thesis -Faculty of Medicine of Ribeirão Preto -University of São Paulo, 2019.Fractures of intra-articular distal end of the radius, besides being quite frequent, are considered of high complexity, especially those with deviation, due to a small fragment. As a consequence of the complexity of these fractures and the lack of consensus on treatment, it is very important to conduct further studies for greater understanding and better surgical planning. Within the last 10 years, locking volar plate has been the method of choice for treating these fractures. When occurring in distal end of the radius, ulnar volar corner, the locking plate does not manage to fixate these fractures, thus new types of treatment have been assessed and analyzed. This research aimed to evaluate fracture of distal end of the radius, ulnar volar corner, in a database. Analising 4 fixation systems and comparing mechanical properties of hook plate to 3 other osteosynthesis systems, by means of mechanical shear testing until the time of failure. Besides validating the finite element method when comparing the maximum displacement obtained to mechanical tests. Regarding the study of prevalence, there was a retrospective analysis of CT scans of the wrist performed within the period from January 2013 to June 2018, at the Rede de Diagnóstico das Américas Sociedade Anônima (DASA) -Rio de Janeiro. A total of 1,141 computerized tomography scans of the wrist were evaluated, out of which 235 had fractures of distal end of the radius, with 128 intra-articular fractures, and 14 of them were ulnar volar corner fractures. At the Bioengineering Laboratory of the Medical School of Ribeirão Preto of the University of São Paulo (USP), mechanical shear tests were performed to determine the mechanical properties of 4 different osteosynthesis systems, in Sawbone™ radius bones (model 1027). The ulnar volar corner fragment under analysis was 15 mm long, 17 mm wide, and 7 mm high in the anterior facet for the semilunar distal end of the radius. For osteosynthesis, fourteen 2.0 mm plates, Medartis™, with 5 holes (hook and support plates) were used. Also, 2.3 mm cortical screws were used for bone fragment fixation in the ulnar volar corner, horizontally and vertically. The mechanical properties assessed were maximum force and relative stiffness. The hook plate osteosynthesis systems showed maximum force and relative stiffness values higher than the other systems and they were considered statistically significant. In the analysis using the finite element method, the systems that used to plates (hook and support) were validated by mechanical testing. The study shows a tendence to low prevalence and a bimodal presentation of fracture of distal end of the radius, ulnar volar corner. The mechanical properties of the model that used a modified hook plate were higher among the 4 fixation models. Through Finite elements study, it was possible to assess separately the mec...

“…Con respecto a las lesiones relacionadas con los tendones flexores o extensores, así como a la lesión del nervio mediano, la RMN puede ser una modalidad muy útil. (35) Una evaluación de la enfermedad del túnel carpiano después de la unión defectuosa de las fracturas radiales distales se puede realizar con éxito con la RMN. (42,43) El principio básico para poder atender una fractura es obtener una reducción precisa de la fractura y luego usar un método de inmovilización que mantenga y mantenga esa reducción.…”

Objetivo: Determinar los factores asociados a las complicaciones post reducción abierta y fijación interna de las fracturas de radio distal en pacientes atendidos en el Hospital de Huaycán 2018-2019. Material y Métodos: El diseño de estudio es analítico, retrospectivo, transversal de casos y controles, donde se evaluaron 60 casos y 120 controles, para determinar los factores asociados a las complicaciones post RAFI de las fracturas de radio distal en el Hospital Huaycán. Resultados: Se evaluaron factores epidemiológicos, antecedentes patológicos y factores quirúrgicos. Entre los factores epidemiológicos asociados se pudo identificar el sexo femenino (p=0,001; OR: 7.5, IC 95%: 2,857-19.688). Con respecto a los antecedentes patológicos fueron hipertensión arterial (p= 0.001; OR: 6.107; IC 95%: 2,611 – 14,287), Diabetes Mellitus (p=0.001; OR: 4.091; IC95%: 1.776 – 9.426), osteoporosis (p=0.003; OR: 3.321; IC95%:1.480 – 7.455). Con respecto a los factores quirúrgicos, las fracturas expuestas (p=0.001, OR: 7.644, IC95%: 3.077 – 18.993), tiempo transcurrido desde el accidente hasta la intervención quirúrgica mayor a 30 días (P= 0,001, OR 4, IC 95%: 1,804-9,794). Conclusiones: Factores asociados a las complicaciones post reducción abierta y fijación interna de las fracturas de radio distal son: el sexo femenino, hipertensión arterial, diabetes mellitus, osteoporosis, fractura expuesta y el tiempo transcurrido desde el accidente hasta la intervención quirúrgica mayor a 30 días.
