The 31-year-old Bayern Munich star, a veteran of the 2006 final when France lost to Italy, has been unable to train with the rest of the squad since joining them last week.
The injury kept Ribery out of Tuesday's 4-0 victory in the friendly against Norway, and he will also be absent for the game against Paraguay on Sunday.
Despite concern over the Bayern star's state of readiness for Brazil Deschamps said he was not planning to call up a replacement for the 31-year-old.
"I'm not thinking about that today," the French boss told a press conference at Les Bleus' training camp in Nice.
The 1998 World Cup winning captain added: "Franck's situation relates to a back problem going back some weeks and months. If we're where we are now it means that there is something (amiss).
"Our aim is to enable him to return for a team session freer than he's been in the last few weeks for Bayern Munich.
"We and above all him are doing everything to find a solution, and there is one.
"He's not here in the process of sleeping, of doing nothing.
"He's got lots of exercises adapted to ensure he'll be in a better physical condition. The aim is that he'll be available for Jamaica (in Lille next Sunday)."
Earlier, Ribery's participation at the World Cup was assured by French Football Federation president Noel Le Graet.
"The French team is counting on Ribery," said Le Graet, who was speaking after the annual general meeting of the federation in Paris.
"He will resume training very soon. The medical examinations he underwent showed that there is no threat of his missing the World Cup."
Ribery, who was also part of the squad that returned in disgrace from the 2010 World Cup exiting in the first round and having gone on strike at one point, had, according to Le Graet, been worried that the problem might be more serious.
"He was a little bit anxious because he had felt a sharp pain in the base of the back but there was nothing to show that it was serious," said Le Graet.
"He will resume training almost certainly next week."
