RESUMEN
INTRODUCTION: The acromioclavicular joint, important part of the shoulder complex is formed by clavicular lateral end and acromial medial border, with high index of injury in different grades, associated to physical activity and work accidents, most commonly in active young adults. OBJECTIVE: To analyze functional outcomes in patients with acromioclavicular dislocation with use of tight rope in one year. Material and methods: Descriptive, prospective, longitudinal, unicentric study, from March 2015 and July 2016 in post-operated patients with diagnosis of acromioclavicular dislocation grade III in Hospital de Traumatología y Ortopedia de Puebla. Patients aged 18 to 45 years were included, active workers, with evolution time 7 days. RESULTS: 17 patients with diagnosis of acromioclavicular dislocation, fourteen (82.4%) male and 3 (17.6%) female. Average age: 29.5 (19 to 44 years) ± 7.475 years; lesion occurred 9 (52.9%) patients in right shoulder and 8 (47.1%) in left side. Average time of the injury: 2.88 (1-7) ± 2,147 days. Average inability granted: 42.06 days. CONCLUSIONS: The open reduction technique and dynamic stabilization of the joint with Tight Rope offers short hospital stay, short time of inability and rapid reintegration to work activity, at 1 year of evolution.
INTRODUCCIÓN: La articulación acromioclavicular es parte importante del complejo articular del hombro, formada por el extremo lateral de la clavícula y el borde medial del acromion. Tiene un alto índice de lesión en grados asociados a actividad física y accidentes laborales. Predomina en jóvenes laboralmente activos. OBJETIVO: Analizar la funcionalidad a un año en pacientes con luxación acromioclavicular grado III, operados con sistema anclaje doble botón. MATERIAL Y MÉTODOS: Estudio descriptivo, prospectivo, longitudinal, unicéntrico, durante Marzo de 2015 a Julio de 2016, en pacientes con luxación acromioclavicular grado III en el Hospital de Traumatología y Ortopedia de Puebla. Se incluyeron pacientes con edad de 18 a 45 años, trabajadores, con evolución mayor de siete días. La estadística fue descriptiva. RESULTADOS: Fueron 17 pacientes; 14 (82.4%) hombres y tres (17.6%) mujeres. Edad promedio: 29.5 (19 a 44 años) ± 7.475 años; nueve (52.9%) pacientes en el hombro derecho y ocho (47.1%) en el izquierdo. Promedio de evolución: 2.88 (1 a 7) ± 2.147 días. Incapacidad promedio: 42.06 días. CONCLUSIONES: La reducción abierta y estabilización dinámica mediante el sistema anclaje doble botón (Tight Rope) ofrece estancia intrahospitalaria corta, poco tiempo de incapacidad, reintegración rápida a la actividad laboral y resultados funcionales adecuados a un año de evolución.

INTRODUCTION: Percutaneous discectomy is a disc decompression technique approved by the FDA that is useful to improve pain caused by a herniated disc. However, its practice is under discussion because the benefits of the technique are controversial. OBJECTIVES: To describe the clinical course of patients with low lumbar disc herniation (L4-L5, L5-S1) treated by percutaneous surgery within one year of surgery and prove that it is a useful surgical option for the relief of symptoms caused by this pathological entity. MATERIAL AND METHODS: Cohort study; the clinical course of 21 patients with lumbar disc herniation treated with percutaneous discectomy manually during March 2011-November 2013, is presented. The evaluation was made before surgery and at four, 30, 180 and 365 days after surgery by numerical pain scale (NPS), Oswestry (IDO) and MacNab criteria. We used nonparametric inferential statistics (Wilcoxon) for differences in proportions. RESULTS: n = 21, six (28.57%) men, 15 (71.42%) women; average age: 37.95, (14-56) ± 10.60 years; the most affected vertebral level was L4-L5 in 57.14% of the patients; the NPS preoperative average was 7.75 (5-9) ± 1.12; at 365 days: average 2.14 (0-7) ± 2.37. The IDO preoperative average was 37% (28-40%) ± 3.06, and at 365 days: 9.52% (0-40%) ± 13.92. The prognosis (IDO) in the presurgical was good to zero (0%) patients and in 15 (71.42%) at 365 days, regular in five (23.80%) and poor in one (4.78%) (p = 0.00, CI 95% 0.00 to 0.13, Wilcoxon); according to MacNab criteria, in 15 (71.42%) patients were excellent and good, poor in four (19.04%) and bad in two (9.52%) (p = 0.00). CONCLUSIONS: Percutaneous discectomy provides good results for the treatment of lumbar disc herniation (L4-L5, L5-S1) at 365 days after surgery.

BACKGROUND: Until very recently, interferon (INF) in Spain was authorized in chronic hepatitis C (C-HCV) at a dosis of 3 megaunits (mu) for 6 months. Nonetheless, the rate of maintained complete response is lower than that obtained with more prolonged treatments. The first aim of this study was to retrospectively know the effectiveness of alpha INF in patients treated for 6 or 12 months with a dosis of 3 or 5-6 MU. The second was to analyze the characteristics of the patients who achieved a maintained complete response. PATIENTS AND METHODS: Patients with C-HCV treated in 9 hospitals in Andalucía, Spain who fulfilled the following conditions were retrospectively analyzed: liver biopsy prior to treatment, positive test for anti HCV and a follow up of at least 6 months after alpha INF treatment. A total of 344 patients were studied: 267 treated with alpha INF-2b, 51 with alpha INF-2a and 26 with lymphoblastoid INF. One hundred ninety-five patients were treated for 6 months and 149 for 12 months. RESULTS: Seventy-seven (22%) of the patients presented maintained complete response, 170 (50%) did not respond and 97 (28%) relapsed. On comparing the three types of interferon used over 6 months, no significant differences were observed. Neither were differences found on comparing the dosis of 3 mu versus 5 or 6 mu. On analyzing the treatments of 6 and 12 months, the following was observed, respectively: maintained complete response 15% vs 32%, relapse 29% vs 30% and non responders 57% vs 38% (p < 0.001). Multivariate analysis demonstrated that the patients who responded the best to INF were those who presented the following characteristics: female sex, age under 40 years last, history of transfusion or IVDA, basal GPT level higher than 145 IU/I, GGT less than 55 IU/I, less evolved histologic lesions and duration of treatment over 12 months. CONCLUSIONS: Of the different treatments analyzed with alpha interferon in chronic hepatitis C, the best was found to be that with 3 mu during 12 months.
