ABSTRACT

Introduction: The results in shoulder fracture hemiartroplasty´s, or fracture dislocation, have been traditionally no predictable. These have been related to difficulty in obtaining a suitable consolidation of the tuberosities. On the other hand, reconstruction with more anatomical fixation have improved the functional results. The purpose of our study is to describe, and analyze, the functional and radiological results of two different techniques of tuberosities fixation in shoulder hemiartroplasty. Material and Methods: Between March of 1996 and December 2005, 47 patients (47 shoulders) underwent hemiarthroplasty by 3- and 4- part displaced proximal humerus fracture, or fracture dislocation. We performed in 29cases (61.7 percent) trans tuberosities sutures technique (group I), and in 18 (38.3 percent) independents sutures technique (group II). The average age and sex distribution, was similar between both groups. Constant score and radiological parameters, as head tuberosity distance (HTD) and consolidation of the tuberosities, were analyzed. Statistical analysis was done with ANOVA and Fischer exact test. P values of less than 0.05 were considered statistical significant. Results: Constant Score revealed a difference in favor to group II (66.2 versus 72.8 points; p = 0,1).Radiographic parameters, showed significant differences in favor of the group II (HTD 16.5 vs 8 mm; and 68 percent versus 100 percent consolidation respectively; p < 0,05). Conclusion: According to our results, and in concordance with international literature, tuberosities fixation with independent sutures allow better consolidation, with smaller superior migration, improving the final functional results.


Los resultados de la hemiartroplastía en fracturas o luxo fracturas de hombro, tradicionalmente han sido poco predecibles. Estos se han relacionado a la dificultad en conseguir una adecuada consolidación de las tuberosidades. Por otra parte, la reconstrucción y fijación más anatómica de éstas, ha permitido mejorar sus resultados funcionales. El objetivo de nuestro estudio es describir, y analizar, los resultados funcionales y radiológicos, de dos técnicas de fijación de las tuberosidades en la hemiartroplastía de hombro. Material y Métodos: Entre marzo de 1996 y diciembre de 2005, 47 pacientes (47 hombros) con diagnóstico de fractura de húmero proximal, o luxo fracturas, en 3 ó 4 partes, fueron tratados con prótesis parcial. Se realizó en 29 casos (61,7 por ciento), la técnica de amarras trans tuberositaria (grupo I), y en 18 (38,3 por ciento) la de amarras independientes a modo de cerclaje (grupo II). La edad promedio y sexo, fueron similares entre ambos grupos. Se analizaron variables como score de Constant, y parámetros radiológicos, como la distancia tuberosidad cabeza humeral (HTD), y la presencia de consolidación de las tuberosidades. El análisis estadístico fue hecho con los tests de ANOVA y exacto de Fisher. Los valores p < 0,05 fueron considerados estadísticamente significativos. Resultados: El score de Constant, presentó una diferencia en favor del grupo II, la que no fue significativa (66,2 vs 72,8 puntos; p = 0,1). Los parámetros radiográficos sí mostraron diferencias significativas, a favor del grupo II (HTD 16,5 vs 8 mm; y 68 por ciento vs 100 por ciento consolidación respectivamente; p < 0,05). Conclusión: De acuerdo a nuestros resultados, y en concordancia con la literatura internacional, la fijación de tuberosidades con amarras independientes permite una mejor consolidación, y menor migración superior, lo que permite mejorar los resultados funcionales.

ABSTRACT

Urinary retention and blood in the urinary meatus are the common signs of trauma of the urethra which may be brought about by crushing injuries such as the "straddle" type, or penetrating injuries from spicules of bones in fractures of the pelvis. The paths of urinary extravasation guide to surgeon in his drainage incisions. The treatment which must be started even on the merest suspicion of a trauma, must be divided into suprapubic drainage of urine and definitive repair. In our hands, the wide anatomic exposure of the injured urethra through the perineo-scrotal region allows for good excision on the scar tissue and correct suturing of defects, employing usually overlying tissues in several layers. We have had to little experience with the use of free skin grafts to be able to write enthusiastically about it, although undoubtedly in selected cases this operation holds a place. (Summary)
