Se presenta el caso de un hombre de 57 años que consulta por parálisis alta del nervio radial, con dolor y prueba de Tinel positiva en la cara lateral del brazo dominante, de inicio súbito, luego de grandes esfuerzos musculares repetitivos, sin mejoría clínica al tercer mes de evolución. Se realizó un tratamiento quirúrgico descompresivo. El paciente tuvo una rápida recuperación a partir del séptimo día, y remisión completa a los 25 días de la cirugía. Conclusión: El atrapamiento del nervio radial en el brazo es un cuadro poco frecuente. Según los estudios publicados, la evolución clínica es variada, pero si no hay remisión o la evolución de la parálisis no es favorable en 3 meses, creemos que la cirugía es el tratamiento de elección.

Objetivo: Presentar una nueva técnica quirúrgica y los resultados clínicos comparativos de pacientes con roturas de tenorrafia primaria o lesiones crónicas del flexor profundo en las zonas I y II de Verdan, tratados con avance tendinoso no convencional. Materiales y Métodos: Se incluyó a pacientes >18 años, con antecedente de lesiones en las zonas I y II de Verdan y un seguimiento mínimo de 36 meses. La serie estaba formada por 13 pacientes (edad promedio 29 años) que fueron divididos en dos grupos según el tipo de lesión (7 con roturas de tenorrafia primaria y 6 con lesiones crónicas del flexor profundo) y la técnica quirúrgica utilizada (alargamiento en Z más sutura término-terminal y sutura lateral del tendón alargado a un flexor vecino indemne en la zona V, respectivamente). Se empleó la Clasificación de Strickland para la evaluación. Resultados: El seguimiento promedio fue de 51 meses. El intervalo promedio entre la lesión y la cirugía fue de 11.7 semanas. Según la Clasificación de Strickland, 8 pacientes tuvieron resultados excelentes; 4, buenos y uno, pobre. El avance tendinoso promedio fue de 20,5 mm en ambos grupos. Conclusiones: El avance tendinoso no convencional para lesiones en las zonas I y II de Verdan, sea en roturas de tenorrafia primaria o lesiones crónicas del flexor profundo, resultó un tratamiento reproducible y eficaz. Palabras clave: Tendón flexor; alargamiento; zetaplastia.Nivel de Evidencia: III

Objective: To report functional and radiologic outcomes of reverse shoulder arthroplasty (RSA) in patients with complex proximal humeral fractures. A second objective was to assess the relation between the greater tuberosity healing and the range of motion (ROM) and the American Shoulder and Elbow Surgeons (ASES) score. Materials and Methods: Sixteen patients treated between 2013 and 2017, older than 65 years old, operated before 4 weeks after the trauma, and with a minimum of 2-year follow-up were included. ASES scores and active ROMs were recorded. Greater tuberosity and the prosthesis position and healing were radiologically evaluated, and the complications and treatment were recorded. Results: The median age was of 74.5 years (IQR 66-78.5), 11 patients were females (69%). According to Neer classification, 11 cases were four-part fractures and 5 were four-part fracture-dislocations. The average time between trauma and surgery was 9.4 days, and the average follow-up was of 29.5 months. The greater tuberosity was healed in 9 cases (56%). Internal rotation: 5 patients (31.25%) were able to reach up with their thumbs to gluteal level, 4 (25%) to T12, 3 (18.75%) to T7, and 4 (25%) to L3. The medians for external rotation and forward flexion were 30° (IQR 17.5°-40°) and 100° (IQR 87.5°-160°). The average ASES score was of 78.3 (IQR 63.3-87.4). There was no significant statistical relation between greater tuberosity healing and forward flexion or ASES score (P=0.24 and P=0.52, respectively). Conclusion: The use of reverse prostheses for complex fractures with greater tuberosity reattachment could lead to good functional outcomes, low complication rates and reoperations. There was no significant statistical relation between ASES score and greater tuberosity healing or failure to heal.

Background: Benzodiazepine use is associated to a risk of abuse of dependency. In Chile benzodiazepine abuse is a public health issue. In an attempt to overcome this problem, several restrictions in their prescription were implemented by the health authority. Despite these measures, inadequate use of benzodiazepines in primary care continues to be frequent. Aim: To study the frequency of benzodiazepine use among primary care patients. Material and methods: Cross sectional survey done during two days, with seven physicians working in public primary care clinics. They applied a structured questionnaire about psychotropic medication use. Results: One hundred eighty eight subjects aged 46.8±17.5 years, 66% women, were interviewed. Thirty two percent were consuming a psychotropic drug and 82% of these corresponded to benzodiazepines. General practitioners and psychiatrists prescribed the drug to 75% and 13% of subjects, respectively. A higher frequency of benzodiazepine use was observed in women and in urban areas. Conclusions: Benzodiazepine use continues to be highly prevalent in primary care patients, in spite of the nationwide implementation of controlled prescriptions (Rev Med Chile 2003; 131: 535-40).
