What is the first step in the Kocher's method to reduce a shoulder dislocation?

The first step in Kocher's method for reducing a shoulder dislocation involves applying traction to the humerus. This initial traction is important as it helps to mobilize the humeral head and create space within the glenohumeral joint, making it easier to maneuver the dislocated joint back into its correct position.

By pulling gently on the arm, the dislocated humeral head is drawn away from the glenoid cavity, which can often alleviate any obstruction preventing proper alignment. This step is crucial because effective distraction facilitates the subsequent movements required to complete the reduction process, making it a foundational part of the technique.

Understanding this step is vital for any medical professional involved in the treatment of shoulder dislocations, as improper methods or sequences could lead to complications or ineffective reductions.
