The Prevalence of Personality Disorder in Hand and Upper Extremity Trauma

Background: Upper extremity is the most common part of the body, which is exposed to injuries with physical, mental, social and economic consequences. Objectives: This research studied the prevalence and types of personality disorders in patients with upper extremity trauma at Hazrat Fatima hospital. Methods: This research studied all patients with upper extremity trauma in a three-month period hospitalized at Hazrat Fatemeh. The Millon Test was filled by all candidates with a clinical psychologist and psychometric supervision. Results were analyzed statistically. Results: This study included 202 male participants with age range of 14 to 70 years old, amongst whom 41.4% had personality disorders. The prevalence of personality disorder in violence and self-injury groups was 72.7% and 39.3% in the group of industrial accidents, which proved a significant difference (P = 0.003). Avoidant personality disorders (P = 001), narcissistic (P = 0.003), anti-social (P = 0.002), borderline (P = 0.001) passive aggressive (P = 0.002) were significantly more common in violence and self-injury group. Conclusions: The present study revealed that the prevalence of personality disorder in patients with upper extremity injuries is more than the society. Due to the high rate of personality disorder in hand trauma victims, we recommended routine psychological evaluation of these patients.
