Yes, WD, that is right. Handlebars are sold with four measurements in mind: rise (height of the bar from the mounting point in the center); end rise (height of the bar from the mounting point at the end of the bar); width (the total width of the bar); center width (the width of the bar in the center where it mounts where the bar is flat before rising); and pull back (the distance from to mounting point to the furthest point on the bar end toward the rider.) There is a fifth measurement that is assumed: you either buy 7/8 or 1" bars to match your mounting. I haven't measured a Bonnie but they are likely 7/8" bars.
Many bars have sufficient rise to totally avoid any need to buy bar risers, the bar itself providing the rise. So in your case you can buy a bar with an inch or two more rise than your stock bar and with a 3-4" pullback and it would meet the needs I think you have to relieve the reaching, which is putting a strain on your shoulder.
Go to
www.denniskirk.com and look at them. Better yet, go there and order their 2006 Metric Bike catalogue. Or call them on their free line, 1-800-969-7504, and ask them to send it to you. It is free; over an inch thick, almost 800 pages of items, and they will send it to you very quickly. The bar selections are on pp. 451-453 and scattered elsewhere. There are also lots of bar riser choices for those who like the shape of their current bars. There are at least 75 choices in bars in that catalogue.
I had one other thought. When I had my accident I dislocated my left shoulder and it was HARD to ride because of the stretch it put on that shoulder. Shoulder occupational therapy exercises really helped. You might try them. Google "dislocated shoulder exercizes" and you will find several sites that have excercizes in PDF format that you can download that have explanations how to do them and line drawings showing how. They are very easy and they really help to loosen up the shoulder and increase normal mobility. They only take about 10 minutes twice a day.
