The verb thrust is uninflected in the past tense and as a past participle. For example, “I was thrust into the spotlight,” “I have thrust myself into the spotlight,” and “I thrust myself into the spotlight yesterday” are all conventionally correct. Thrusted is an old variant that has never caught on in general usage, and it is rare in edited writing.
