I have read about it. All Sakura has to do is stay out of her range. According to Narutowiki it's a short to long range attack. Even though Sakura is a close-combat fighter she can just move out of Hinata's range (who is also mostly close-combat). Once Sakura is out of Hinata's range of course Hinata will advance her to try to attack since Hinata won't spam the empty palm attack if it can't reach Sakura. While Hinata is attacking Sakura, Sakura can simply study her pattern of attack since that is what Tsunade trained her to do as a medical ninja. Once she has fully assessed Hinata's attack pattern she can simply dodge and strike Hinata whenever she needs to.
I'm not saying that Hinata will be oblivious to an attack from Sakura, but Sakura's abilities as a medical ninja (not healing, but dodging and picking up on enemy attack patterns), will make this battle harder than most people think.
Even if saukra does stay out of range/dodge i dont see how she can get a blow on hinata, If sakura stays at long range she cant do anything she will be forced into close range at one point
not saying hinata is faster but sakura isen't exactly quick and her punchs are powerful but quite slow, her only chance would be a suprise attack but with almost 360 vision its kinda of hard to get a suprise attack on a byakugan user
Also if hinata gets a few hits on sakuras chakra points in her arms (kind of like neji did to hinata) she cant really focus chakra into her fists or heal, sakura's problem is her lack of jutsu's really we havn't seen her use any at all
Goin by narutowiki the Twin Lion Fists:
it was shown that this technique has enough power to destroy Pain's chakra rods, as well as momentarily stunning the target after the attack lands
So if sakura gets his by that shes finnished
