Investigation Into the Effects of Intra-Articular Steroid on Post-Traumatic Osteoarthritis in Distal Radius Fractures: A Randomized Controlled Pilot Study.

PURPOSE: The aim of this prospective, randomized, controlled, double-blinded pilot study was to determine the rates of post-traumatic osteoarthritis and assess joint space width in the presence or absence of a single intra-articular injection of corticosteroid after an acute, intra-articular distal radius fracture (DRF). METHODS: Forty patients received a single, intra-articular, radiocarpal joint injection of 4 mg of dexamethasone (DEX) (n = 19) or normal saline placebo (n = 21) within 2 weeks of a surgically or nonsurgically treated intra-articular DRF. The primary outcome measure was minimum radiocarpal joint space width (mJSW) on noncontrast computed tomography scans at 2 years postinjection. Secondary outcomes were obtained at 3 months, 6 months, 1 year, and 2 years postinjection and included Disabilities of the Arm, Shoulder, and Hand; Michigan Hand Questionnaire; Patient-Rated Wrist Evaluation; wrist range of motion; and grip strength. RESULTS: At 2-year follow-up, there was no difference in mean mJSW between the DEX group (2.2 mm; standard deviation, 0.6; range, 1.4-3.2) and the placebo group (2.3 mm; standard deviation, 0.7; range, 0.9-3.9). Further, there were no differences in any secondary outcome measures at any postinjection follow-up interval. CONCLUSIONS: Radiocarpal joint injection of corticosteroid within 2 weeks of an intra-articular DRF does not appear to affect the development of post-traumatic osteoarthritis within 2 years follow-up in a small pilot cohort. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Fracturas del extremo distal del radio en el esqueleto inmaduro: estudio epidemiológico en el Centro Hospitalario Pereira Rossell / Fraturas da extremidade distal do rádio no esqueleto imaturo: estudo epidemiológico no Hospital Pereira Rossell / Fracture of the distal end of the radius in children: epidemiological study at the Pereira Rossell Hospital Center

Objetivo principal: Conocer la epidemiologia de las fracturas del cuarto distal del radio en el esqueleto en crecimiento y el tratamiento realizado en el CHPR en los años 2017 y 2018. Objetivos específicos: Valorar re-desplazamiento, necesidad de re manipulación, complicaciones, re-fractura. Metodología: Estudio observacional descriptivo retrospectivo. Criterios de inclusión: pacientes de 0 a 14 años con fractura de radio distal (fisaria, metafisaria y suprametafisaria) valorados en el CHPR entre 1 enero del 2017 y 31 diciembre del 2018. Criterios de exclusión: pacientes con radiografía normal, fracturas en miembros con malformaciones, infecciones óseas, patología tumoral maligna o benigna. Obtención de datos: Valoración de radiografías de puño y antebrazo realizadas en el CHPR en 2017 y 18, iniciales y evolutivas. Se analizaron: edad, sexo, fecha fractura, topografía de la fractura, desplazamiento inicial, tratamiento, evolución radiográfica y complicaciones. Resultados: se incluyeron 662 pacientes. Siendo en su mayoría de género masculino (65%), con una media de 9 años, miembro derecho (61%), en los meses de verano (36%). En cuanto a la topografía se evidenció una frecuencia mayor en fracturas tipo rodete y metafisarias (31.72% y 31.57%), seguido por suprametafisaria (18.43%) y fisaria (18.28%). El tratamiento realizado fue ortopédico en el 86.56% de los casos, mientras que quirúrgico fue el 12.84%, en su gran mayoría con alambres de Kirschner (11,2%). El tiempo de inmovilización promedio fue de 6 semanas, con un porcentaje de complicaciones del 14.05% del total de las fracturas. Conclusiones: Se valoraron las características de los pacientes y fracturas de radio distal en el CHPR en los años 2017 y 18, siendo un total de 662 fracturas, en las que su mayoría se realizó tratamiento ortopédico con un índice de complicaciones que ronda el 14%, siendo mayor cuanto mayor es el desplazamiento inicial de la fractura.

Objetivo principal: Conhecer a epidemiologia das fraturas do quarto distal do rádio no esqueleto em crescimento e o tratamento realizado no CHPR nos anos de 2017 e 2018. Objetivos específicos: Avaliar re-deslocamento, necessidade de remanipulação, complicações, refratura. Metodologia: Estudo observacional descritivo retrospectivo. Critérios de inclusão: pacientes de 0 a 14 anos com fratura do rádio distal (fisário, metafisário e suprametafisário) avaliados no CHPR entre 1º de janeiro de 2017 e 31 de dezembro de 2018. Critérios de exclusão: pacientes com radiografias normais, fraturas em membros com malformações, osso infecções, patologia tumoral maligna ou benigna. Coleta de dados: Avaliação das radiografias de punho e antebraço realizadas no CHPR em 2017 e 18, inicial e evolutiva. Foram analisados: idade, sexo, data da fratura, topografia da fratura, deslocamento inicial, tratamento, evolução radiográfica e complicações. Resultados: 662 pacientes foram incluídos. Sendo maioritariamente do sexo masculino (65%), com média de 9 anos, membro direito (61%), nos meses de verão (36%). Em relação à topografia, foi evidenciada maior frequência nas fraturas da borda e metafisárias (31,72% e 31,57%), seguidas das suprametafisárias (18.43%) e fisárias (18.28%). O tratamento realizado foi ortopédico em 86.56% dos casos, enquanto cirúrgico em 12.84%, sendo a maioria com fios de Kirschner (11,2%). O tempo médio de imobilização foi de 6 semanas, com percentual de complicações de 14.05%. Conclusões: Foram avaliadas as características dos pacientes e fraturas do rádio distal no CHPR nos anos de 2017 e 18, com um total de 662 fraturas (0,9 por dia), em que a maioria foi submetida a tratamento ortopédico com índice de complicações que fica em torno de 14%, sendo maior quanto maior for o deslocamento inicial da fratura.

Title: Fractures of the distal end of the radius in the immature skeleton. Epidemiological study at the Pereira Rossell Hospital Center. Main objective: To know the epidemiology of fractures of the distal fourth of the radius in the growing skeleton and the treatment carried out in the CHPR in the years 2017 and 2018. Specific objectives: To assess re-displacement, need for re-manipulation, complications, re- fracture. Methodology: Retrospective descriptive observational study. Inclusion criteria: patients aged 0 to 14 years with distal radius fracture (physeal, metaphyseal and suprametaphyseal) evaluated at the CHPR between January 1, 2017 and December 31, 2018. Exclusion criteria: patients with normal radiographs, fractures in limbs with malformations, bone infections, malignant or benign tumor pathology. Data collection: Assessment of fist and forearm X-rays performed at the CHPR in 2017 and 18, initial and evolutionary. The following were analyzed: age, sex, fracture date, fracture topography, initial displacement, treatment, radiographic evolution and complications. Results: 662 patients were included. Being mostly male (65%), with an average of 9 years, right limb (61%), in the summer months (36%). Regarding the topography, a higher frequency was evidenced in rim and metaphyseal fractures (31.72% and 31.57%), followed by suprametaphyseal (18.43%) and physeal (18.28%). The treatment performed was orthopedic in 86.56% of the cases, while surgical was 12.84%, mostly with Kirschner wires (11.2%). The average immobilization time was 6 weeks, with a percentage of complications of 14.05%. Conclusions: The characteristics of the patients and fractures of the distal radius in the CHPR in the years 2017 and 18 were evaluated, with a total of 662 fractures (0.9 per day), in which the majority underwent orthopedic treatment with an index of complications that is around 14%, being greater the greater the initial displacement of the fracture.
