Anatomically and biomechanically, the shoulder joint is one of the most unstable and frequently dislocated joints in the body, accounting for approximately 50% of all joint dislocations. The incidence of anterior dislocation of the shoulder joint is 2% to 8% in the population, and it accounts for 1/3 of shoulder emergencies. in the past, it was thought that failure to fix the shoulder joint for 3-4 weeks after the initial dislocation reset was the main reason for the recurrence of dislocation, but many scholars believe that other factors are more important. the occurrence of recurrent dislocation depends largely on the site and nature of the injury during the first dislocation. young people, especially athletes, often experience dislocation Recurrence, the duration of fixation does not seem to affect the stability of the shoulder joint, while the degree and location of the first trauma is related to the frequency of recurrence. Habitual shoulder dislocations generally occur in young and middle-aged men between the ages of 20 and 50, mainly due to the mild degree of injury and the lack of symptoms, such that many people have an indifferent mindset about the first dislocation. The pain disappears quickly after the manual reset and the activity is normal, so many patients think it is completely cured and do not pay attention to it, thus laying the root of the problem and leading to habitual shoulder dislocation later. ”Once the dislocation becomes a habit, you have to be careful when doing other sports in your daily life. For example, you have to be very careful when fishing, putting things up high, drying clothes, or changing light bulbs on the ceiling, which is very inconvenient. In severe cases, the shoulder joint may fall off automatically when walking or even turning over in bed at night, and it may be difficult to reset the shoulder joint manually. Currently, for the treatment of the first dislocation of the shoulder joint, the International ISAKOS Association treatment guidelines recommend that young patients undergo arthroscopic minimally invasive surgery to repair the dislocation when it first occurs, so that the injury is completely cured and can effectively prevent habitual dislocation of the shoulder joint. Therefore, when the shoulder is traumatized or suspected to be dislocated, you should go to a specialized hospital for examination and treatment as soon as possible, avoiding blind self-repositioning and prohibiting the use of rough repositioning techniques that may aggravate the injury.
