Introduction: The shoulder joint is the most flexible joint in the human body, and consequently it is also the most prone to dislocations. The commonest group of injured persons are young men suffering from damage to the static stabilizers of the joint, or elderly people with frequent rotator cuff tears. First aid measures for shoulder joint dislocation include rest, placing the injured limb in a comfortable position and immobilization. According to the findings from the reviewed literature, the reason for the dislocation is most often a traumatic event. Additionally, it is of great importance to follow the guidelines and first aid measures in order to provide efficient further treatment of the injury. This enables quick and effective repositioning of the shoulder joint, which brings less additional complications and injuries. Purpose: The purpose of this Thesis is to examine the problem of shoulder joint dislocation, to determine the risk factors, study the current guidelines of first aid measures for taking care of such injuries, and finally, to analyze the advantages and disadvantages of repositioning outside the hospital care. Methods: In order to demonstrate the effectiveness of first aid in case of shoulder dislocation, we carried out a prospective study of patients with shoulder dislocation treated at the UKC Ljubljana, Emergency Surgery Unit. We interviewed the patients, and reviewed their medical documentation at the first and follow-up examinations. Results: A total of 7 injured people participated in our research, of which 3 male and 4 female patients with an average age of 61.4 years. We interpreted the obtained results and presented them in tables. Five of the seven interviewees reported positive first aid measures and a rapid improvement in the condition after the doctor’s repositioning of the dislocated shoulder joint. Discussion and conclusion: In our prospective observational study of patients with shoulder joint luxation we proved that timely and effective first aid measures had a beneficial effect on the course of rehabilitation after shoulder luxation. On average, the injured used less painkillers and faster began with rehabilitation. At the same time, the injured did not suffer neurovascular injuries which are, according to the relevant literature, expected to occur. Namely, the literature states there is a 19-55% possibility for nerve injuries and 0-2% for vascular injuries right after the first shoulder dislocation. Repositioning the shoulder joint outside the hospital care proved to have some advantages, such as fast pain reduction and easier repositioning due to relaxed muscles. In case of the therapist's insufficient experience, neurovascular or bone injuries may occur during the repositioning in the field. Therefore, if we want to improve the treatment results, an appropriate level of experience and knowledge of first aid measures in the field are needed. Seen from this point of view, the current first aid guidelines do not recommend repositioning in the field.
