The Relationships between the Clinical Manifestrations of Anterior Glenohumeral Instability and The Qualitative Factors of a First Dislocation.

Abstract

[purpos] The purpose of this study was to evaluate the relationships between the clinical manifestations of an anterior glenohumeral instability and the qualitative factors of a first dislocation.
[Materials and Methods] We retrospectively reviewed 210 patients (210 shoulders,178 males,32 females). The patterns of glenohumeral anterior instability were divided into 10 groups by combination of the dislocation, subluxation and dead arm syndrome. These 10 patterns were compared with the causes of the first dislocation, participation in sports, and the period of fixation using a sling after reposition.
[Results] Participation in sports was a high (83-88%) cause for a first dislocation, but there were no statistical differences between the 10 patterns. The force to the abducto-external position was highly concerned in the injury mechanism, but again there were no statistical differences between the 10 patterns.
[Conclusion] There were no statistically significant differences between the patterns of glenohumeral anterior instability and the causes of the first dislocation, participation in sports, and the period of the immobilization.
