In most cases I read... it is more often the case where a small fish is placed in a tank much too large for it that you get the broken back issues. Smaller tanks for small gars actually is the better way to go than place them quickly in large tanks...This is NOT me saying you should keep large fish in small tanks..This is me saying that it is best to slowly step up tank size as the fish grows. Gars are elongate torpedo shaped fish they have a very hard time slowing when they hit a fast start in response to some type of stimulus. Put them in a large tank they build up momentum that is enough to cause serious injury (this is especially true in the conventional rectangular tanks with flat sides)
Gars are not that inflexible of fish...Actually they are no more inflexible that any other fish of their body type. It is actually the large head and snout of the fish that reduces their turning ability. They take just a bit more to complete a circle than a typical fish does due to this. I have had 18 inch Longnosed gar that where temporarily being held in 18 inch tanks Hit a fast C start and turn quickly and easily in the space available.
