Clyne sustained the injury back in July during pre-season and has not featured for Liverpool since.
The 26-year-old was first suffering with a back problem at the end of last season, in May.
Nathaniel Clyne is set to spend up to another three months on the sidelines after undergoing an operation on his back injury.
"That's how back problems are", Liverpool manager Juergen Klopp said earlier this month.
Now, it has emerged that Clyne "underwent minor corrective surgery on his back on Monday and that he will now be unavailable to Klopp until February at the latest".

Lambie dismissed concerns that she was ineligible for parliament last week after rumours started to surface her dad was a British citizen.
Defensive reinforcements may be looked at through the transfer market in January, but how much damage this injury could do to Liverpool's season until then remains to be seen.
"So, in this moment all I can really say with certainty is that we will assess Sadio as soon as he lands back in the country and make decisions on what rehab and treatment gives him the best chance of being back fit and strong for the important fixtures we have coming".
Perhaps the biggest indicator of the injury was his name missing from the list of Liverpool group stage Champions League squad.
Indeed, Gomez has taken his chances to the point that he was called up to Gareth Southgate's England squad for their November friendlies against Germany and Brazil, making his worldwide debut in the 0-0 draw with Germany at Wembley and marking himself as a genuine challenger for his clubmate's place on the plane for Russian Federation in the summer.
