Shoulder dislocations are a relatively rare occurrence (0.08 per 1000) but feature disproportionately frequent among active men under the age of 30, doctors are reducing their dislocations and then sending them off to rehab for stabilization and retraining.
The two popular methods to reduce shoulders are the Kocher and the Milch. Kocher’s can be seen here and Milch’s here. Ashton and Hassan, 2006 decided to run a literature review for comparisons between the 2 techniques.
In a 40 year search, they found 304 papers discussing shoulder dislocation using the techniques but only 1 (ONE) which compared them. The data was not consistent or statistically significant one way or the other.
While not a major occurrence, research into this area is merited as these two techniques are being used and healthy, mobile shoulders are a necessity in everyday life- particularly among athletes and active duty military personnel who are more likely to dislocate (in some studies, it jumps as high as 1.69 per 1000 or 20x higher in this population compared to the average).
Given that therapists regularly see patients post-reduction by the ER, I was quite surprised to see that no comparison had been done. This leaves ER physicians either falling solely on their training or whatever feels comfortable rather than what may or may not work better for patient outcomes. If someone wants to do a research project and is looking for a project, this right here is one that needs to be done.
