"The closure of the borders means that the most vulnerable victims of the conflict, those badly injured by the war, no longer have the chance to survive," said Luis Eguiluz, MSF's head of mission in Jordan.
"Until they have renewed access to Jordan, they will be unable to receive the lifesaving medical care they desperately need," he warned in a statement.
MSF, which has opened a surgical department in the town of Ramtha, five kilometres (three miles) from the border, urged Jordan to allow "the medical evacuation of war-wounded Syrians".
The International Committee of the Red Cross issued a separate appeal to the international community to come to the aid of the trapped refugees.
An ICRC statement said the refugees are "in need of urgent assistance" and that "they are living in extremely harsh conditions" in the desert no-man's land.
"The reticence by so many governments to take in more Syrian refugees means that the fate of these asylum seekers hangs in the balance," said the ICRC.
"This is not just about Jordan. The crisis... reflects an international failure to protect and help people affected by conflict and who are in desperate need," said ICRC regional director Robert Mardini.
In July, Jordan -- which already hosts hundreds of thousands of Syrian refugees -- agreed to a one-off aid delivery for those trapped on its border after an appeal was made by the United Nations.
