ABSTRACT

El Os trigonum (OT) y el Proceso de Stieda (PS), corresponden a la osificación separada o extensiva del tubérculo lateral de la cara posterior del talus (TA), respectivamente. Son indicados como factores causales del Síndrome del Impacto Posterior del Tobillo (SIPT), disturbio, agudo o crónico, con dolor en la región posterior del tobillo a los movimientos del pie. El objetivo fue analizar la importancia morfológica de la presencia del OT y/o PS y su posible relación con el SIPT. Fueron utilizados 80 TA secos. La morfometría del TA y del Tubérculo Lateral del TA (TL) fueron calculadas y expresas como: LTA = largo total del TA; ATA = ancho total del TA; LTL/LPS = largo total de TL/PS; ETL = espesor total de TL/PS. Los análisis mostraron valores de LTA: 55,22 (+/-4,16) mm; ATA: 39,51 (+/-2,46) mm; LTL/LPS: 8,06 mm (+/-2,14) y ETL: 8,46 (+/-1,01) mm. Nuestros resultados ofrecen informaciones no encontradas en la literatura especializada y ayudan en el diagnóstico y tratamiento del SIPT.


Os Trigonum (OT) and Stieda Process (SP), separate or extensive ossification of the lateral tubercule of posterior face of Talus (TA), respectively, are indicative of causal factors of the Posterior Impingement Syndrome of The Ankle (PISA) - disturbance, sharp or chronic pain, with pain in the posterior region of the ankle caused by foot movements. The objective of this study was to analyze the morphological importance of the presence of OT and or SP and the possible relationship with PISA for which we used 80 dry TA. The morphometry of TA and Lateral Tubercule of TA (LT) were calculated and expressed as mean: LTA= total length of TA; WTA= total width of TA; LLT/LPS= total length of LT/SP; TLT= total thickness of LT/SP. The measures were LTA: 55.22 (+/-4.16) mm; WTA: 39.51 (+/-2.46) mm; LLT/LPS: 8.06 (+/-2.14) mm; TLT: 8.46 (+/-1.01) mm. Our results provide useful information not found in the specialized literature and are of assistance in the diagnosis and treatment of PISA.
