Evaluation of Recurrence Rate and Risk Factors Affecting Recurrence of Recurrent Shoulder Dislocation in Kashani Hospital in 2017-2018

In this article, the prevalence of recurrent anterior dislocation of the shoulder and the effect of factors such as age, occupation, primary cause and gender on it have been investigated.

This study aimed to investigate the factors related to the frequency of recurrent anterior shoulder dislocation in clients of the Orthopedic Ward of Kashani Hospital, Isfahan City, Iran, in 2017-2018.

The present research is a cross-sectional study. The study population comprised all patients with traumatic and anterior shoulder dislocation referred to Kashani Hospital during 2017-2018. The sampling method in the present study was census. The patients were asked by phone or in person after their presence about the recurrences of dislocations between the beginning of 2017 and the end of 2018. The obtained data were analyzed in SPSS version 25.

Out of 256 patients, 22% had a recurrence of dislocation. The recurrence rate of dislocation in less than 20 years patients was 40%, and in 20 to 40 years was 63%. The highest recurrence rate of dislocation was reported in the age group of 20 to 40 years in the present study. Based on the present study results, the recurrence rate of dislocation in the age-group of 20-40 years was significantly higher than in other groups. There was no significant relationship between gender and recurrence of dislocation in the subjects (P>0.05). Significance was observed in the primary cause and type of occupation in recurrence of dislocation (P<0.05).

The recurrence rate of dislocation in the patients who suffered from dislocations for the first time was 22%. Based on the results, the rate of recurrence of dislocation in the present study was lower than the rate of recurrence of dislocation in similar studies.
