ABSTRACT

INTRODUCCIÓN: Las fracturas por estrés son lesiones producidas por el sobreuso de ciertas extremidades, generando fatigas repetitivas en el hueso con insuficientes periodos de descanso, trastornos hormonales, entre otras. Se produce una elevada actividad osteoclástica y una menor actividad de los osteoblastos a nivel cortical. OBJETIVO: Determinar los factores asociados a fractura por estrés en un centro médico de la Marina de Guerra de Perú. METODOLOGÍA: Se realizó una investigación de tipo observacional analítica de casos y controles. La variable dependiente fue la fractura por estrés, confirmada por resonancia magnética de los pacientes. Las variables independientes fueron edad, sexo y nivel de calcemia tomadas a partir de la historia clínica; el nivel socioeconómico y tiempo de actividad física diaria fueron datos recogidos mediante encuesta. Se obtuvieron los Odds ratio crudos y ajustados con un intervalo de confianza de 95%. RESULTADOS: Se trabajó con un total de 238 pacientes (119 casos y 119 controles), de los cuales 79,8% fueron varones y 20,2% fueron mujeres; la media de edad fue de 20,25 años. En el análisis bivariado se encontró asociación de fracturas por estrés con el sexo masculino (Odds ratio: 3,00; intervalo de confianza 95%: 1,51 a 5,95), hipocalcemia (Odds ratio: 2,83; intervalo de confianza 95%: 2,32 a 3,44), más de dos horas de actividad física diaria (Odds ratio: 24,74; intervalo de confianza 95%: 12,51 a 48,95) y un nivel socioeconómico C (Odds ratio: 6,66; intervalo de confianza 95%: 2,82 a 15,74). Mantuvieron su asociación en el análisis multivariado el tiempo de actividad física (Odds ratio: 44,46; intervalo de confianza 95%: 17,93 a 110,22) y el nivel socioeconómico C (Odds ratio: 22,57; intervalo de confianza 95%: 7,03 a 72,74). CONCLUSIÓN: Las fracturas por estrés estuvieron asociadas al tiempo de actividad física y a un nivel socioeconómico menor. Son necesarios más estudios para evaluar la relación con otros factores en la población militar de Perú.


INTRODUCTION: Stress fractures are injuries produced by the overuse of certain extremities, generating repetitive fatigue in the bone with insufficient rest periods and hormonal disorders, among others. High osteoclastic activity and lower activity of the osteoblasts at the cortical level occurs. OBJECTIVE: To determine the factors associated with a stress fracture in a single medical center of the Peruvian navy. METHODS: We conducted an observational, analytical case-control study. The dependent variable was stress fracture confirmed by magnetic resonance imaging of the patients; the independent variables were age, sex, calcemia, socioeconomic status, and time of daily physical activity. All data were extracted from the medical records. Crude and adjusted odds ratios were calculated with 95% confidence intervals. RESULTS: The sample was comprised of 238 patients (119 cases and 119 controls), of which 79.8% were male, and 20.2% were female; the average age was 20.25. In the bivariate analysis, stress fractures were associated with male sex (odds ratio 3.00; 95% confidence interval 1.51 to 5.95), hypocalcemia (2.83; 2.32 to 3.44), more than two hours of daily physical activity (24.7; 12.51 to 48.95) and socioeconomic level C (6.66; 2.82 to 15.74). Time dedicated to physical activity (adjusted odds ratio 44.46; 95% confidence interval 17.93 to 110.22) and socioeconomic level C (adjusted odds ratio 22.57; 95% confidence interval 7.03 to 72.74) were associated in the multivariate analysis. CONCLUSION: We found that stress fractures were associated with physical activity time and a lower socioeconomic level. Further studies are needed to evaluate the relationship with other factors in the military population of Peru.

ABSTRACT

BACKGROUND: To characterize the recently issued femur shaft insufficiency fracture in terms of a patient's own epidemiological status. METHODS: Fourteen patients were treated for insufficiency fracture from July 2002 to June 2008, excluding cases including the risk factors of insufficiency fracture. All patients were female, and their mean age was 75.6 years (range, 65 to 89 years). The mean follow-up period was 50.6 months (range, 14 to 86 months). RESULTS: The mean body weight of the Koreans in the same age group was 58.1 +/- 9.7 kg, and the mean height was 155.5 +/- 8.8 cm. The mean body weight of our insufficiency fracture patients was 45.7 kg and it was statistically significantly lower than that of the Koreans in the same age group (p < 0.001). The mean height was 147.3 cm and it was significantly shorter than the mean height of the Koreans in the same age group (p = 0.002). In regard to menopausal time, the mean menopausal time of the Koreans was 48.0 +/- 4.2 years, it was 44 years in our study, as menopause occurred statistically significantly earlier (p = 0.017). The patients with insufficiency fracture showed statistically lower weight, shorter stature and an earlier menopausal period than that of the general population. CONCLUSIONS: In early menopausal, underweight, and short patients prescribed osteoporosis medication for an extended period of time, if predromal symptom is present, it is necessary to suspect insufficiency fracture of the femur.

ABSTRACT

La resonancia magnética ha mostrado ser una herramienta eficaz para el diagnóstico precoz de las fracturas por estrés y para la determinación de la gravedad de estas lesiones. El objetivo de este estudio fue determinar la relación entre la gravedad de las fracturas por estrés en deportistas, determinada por resonancia magnética y la morbilidad, estimada por el tiempo de retorno al deporte. Se estudiaron 34 casos de fracturas por estrés, correspondientes a 29 deportistas (12 mujeres; 17 varones; edad 26.3 ± 12.5 años), medianteradiografías y resonancia magnética. Las lesiones fueron clasificadas en cuatro grados según la escala de Arendt. Se determinaron la localización anatómica, el nivel de actividad, el tiempo de diagnóstico y el tiempode retorno a la actividad deportiva. Los huesos más afectados fueron la tibia (n=12; 35.2%), el escafoides tarsiano (n=5; 14.7%) y los metatarsianos (n=4; 11.7). La gravedad de las lesiones fue: grado 1: 14.7%; grado 2: 14.7%; grado 3: 38.2%; grado 4: 32.4%. La correlación entre la gravedad de la lesión y el tiempo de recuperación fue de r=0.66 (p=0.0002). Como conclusión, existe una correlación positiva significativa entre la gravedad de la fractura por estrés, determinada por resonancia magnética, y el tiempo de recuperación. La utilización sistemática de esta clasificación puede ayudar a definir con mayor precisión el cuadro clínico, controlar la rehabilitación y estimar el retorno a la actividad deportiva.


Magnetic resonance imaging is a useful tool for stress fractures (SF) diagnosis, allowing the estimation of injury severity. The aim of this study was to determine the relation between the severity of SF in athletes determined by magnetic resonance imaging and the morbidity estimated as the time to return to sport. Thirty-four cases of stress fractures, (29 athletes; 12 female, 17 male; age 26.3 ± 12.5), were studied by radiographs and magnetic resonance imaging. Injuries were classified according to Arendt´s scale and they were analyzed according to site, activity level, delay in diagnosis and time needed to return to sports. The tibia was the most affected bone (n=12; 35.2%), followed by the tarsal navicular (n=5; 14.7%), and the metatarsals (n=4; 11.7%). Injury severity according to magnetic resonance imaging appearance was: grade 1=14.7%; grade 2=14.7%; grade 3=38.2%; grade 4=32.4%. The main finding was the positive significant correlation between injury severity and recovery time (r=0.66, p=0.0002). In conclusion, significant correlation exists between stress fracture injury severity determined by magnetic resonance image and recovery time in athletes. The use of a systematic graded magnetic resonance image evaluation may assist the physician to define clinical management, supervise the rehabilitation program and estimate the return to sport activity.
