To describe the functional results of arthroscopic treatment in patients with femoroacetabular impingement (FAI) and subspine impingement (SSI) evaluated with a 3-dimensional (3D) dynamic study. Methods: This was a retrospective observational study of patients with a diagnosis of FAI and SSI, evaluated with a 3D dynamic computed tomography scan with Move Forward software, who underwent hip arthroscopy between February 2015 and December 2017. Measurements of the alpha angle, femoral anteversion, acetabular anteversion, lateral center-edge angle, and Tönnis angle were extracted from the 3D dynamic study. Functionality was evaluated using the Western Ontario McMaster Universities Osteoarthritis Index before and 12 months after surgery. Results: We analyzed 22 hips in 17 patients (9 female and 8 male patients) with an average age of 34.6 AE 14.3 years. Of the 22 hips, 15 had cam morphology, 6 had mixed morphology, and 1 had pincer morphology. Of the hips, 11 had a type I spine, 10 had type II, and 1 had type III. The average alpha angle, Tönnis angle, femoral anteversion, and acetabular anteversion were 61.9 AE 11.1 , 2.5 AE 6.4 , 8.8 AE 6.8 , and 15.1 AE 7.1 , respectively. The median lateral center-edge angle was 38.1 (interquartile range, 32.6-43.5). At 1-year follow-up, a decrease in the Western Ontario McMaster Universities Osteoarthritis Index score (P ¼ .001) and an increase in the flexion angle (P < .001) were observed. No cases needed posterior surgical revision because of persistent pain. Conclusions: Arthroscopic treatment provides symptom relief and good functional results in patients with FAI and SSI. Level of Evidence: Level IV, therapeutic case series.

Background: The extravasation of fluid into the intra-abdominal space is recognized as a possible complication of hip arthroscopic surgery/endoscopy. The exposure of anatomic areas to elevated pump pressures and high volumes of irrigation fluid increases the risk of fluid leakage into anatomic spaces around the hip joint, especially to the abdomen and pelvis. Purpose: To estimate the incidence and risk factors related to intra-abdominal fluid extravasation (IAFE) after hip endoscopy or arthroscopic surgery. Study Design: Cohort study; Level of evidence, 2. Methods: A prospective study was carried out between June 2017 and June 2018. A total of 106 hip procedures (endoscopy or arthroscopic surgery) performed for extra- or intra-articular abnormalities were included. Before and after surgery, in the operating room, ultrasound was performed by a trained anesthesiologist to detect IAFE. The hepatorenal (Morison pouch), splenorenal, retroaortic, suprapubic (longitudinal and transverse), and pleural spaces were examined. Patients were monitored for 3 hours after surgery to assess for abdominal pain. The data collected included maximum pump pressure, duration and volume of irrigation fluid (Ringer lactate), total surgical time, and traction time. Results: The incidence of IAFE was 31.1% (33/106; 95% CI, 23.1%-40.5%). The frequency of IAFE was 52.9% (9/17) in cases with isolated extra-articular abnormalities and 15.9% (7/44) in cases with isolated femoroacetabular impingement; in cases with both extra- and intra-articular abnormalities, the frequency was 37.8% (17/45). An intervention in the subgluteal space was identified as a risk factor for IAFE (odds ratio, 3.62 [95% CI, 1.47-8.85]). There was no statistically significant difference between groups (with vs without IAFE) regarding total surgical time, maximum pump pressure, or fluid volume. Postoperative abdominal pain was found in 36.4% (n = 12) of cases with IAFE compared with 2.7% (n = 2) of cases without extravasation ( P < .001). No patient with IAFE developed abdominal compartment syndrome. Conclusion: IAFE was a frequent finding after hip arthroscopic surgery/endoscopy in patients with extra-articular abnormalities. Exploration of the subgluteal space may increase the risk of IAFE. Pain and abdominal distension during the immediate postoperative period were early warning signs for IAFE. These results reinforce the need for careful intraoperative and postoperative monitoring by the surgeon and anesthesiologist to identify and avoid complications related to IAFE.

INTRODUCCIÓN: En el ataque cerebrovascular (ACV), el tiempo entre el inicio de los síntomas y la administración de la terapia de reperfusión está asociado al desenlace. Existe un claro beneficio cuando los pacientes son transportados por los servicios médicos de emergencias (SEM), y en el menor tiempo posible. OBJETIVO: Determinar los tiempos entre el despacho de la ambulancia y la llegada del paciente al servicio de urgencias, en los traslados por ACV realizados por el SEM público en Bogotá, durante los años 2013 y 2014. MATERIALES Y MÉTODOS: Estudio observacional descriptivo de cohorte histórica, de los traslados por ACV realizados por los vehículos de emergencia del Programa de APH del Centro Regulador de Urgencias y Emergencias de Bogotá. RESULTADOS: Se incluyeron 2.161 traslados, 1.218 corresponden al año 2013 y 943 al año 2014. La mediana del tiempo a la escena fue de 13 y 12 minutos (RIQ 9-19 y 8-17 para los años 2012 y 2013 respectivamente), 30 minutos para el tiempo de evaluación (RIQ: 22-39 y 22-36 para los años 2013 y 2014 respectivamente) y 63 minutos para el tiempo total para ambos años (RIQ 50-79 y 49-72, para los años 2013 y 2014 respectivamente).
