It follows an RTÉ documentary on waiting lists
Health Minister Simon Harris says a scoliosis theatre at Crumlin Children's Hospital in Dublin will open in April.
Minister Harris told the Dáil it will handle at least 194 operations this year.
He has met with the hospital's CEO, after it emerged the theatre was built but has not been sufficiently staffed to open.
Mr Harris was seeking answers for why the €3m theatre was not being used.
"This will see significant reductions in waiting lists for scoliosis and waiting times for scoliosis patients.
"At the end of this month, I will receive - from the HSE and the Children's Hospital Group - an Action Plan on Scoliosis.
"I will engage with all parties anon in this House and with advocacy groups in relation to that.
"And in addition to that, by June we will have an additional orthopedic post filled".
Mr Harris met with the Health Service Executive (HSE), the National Treatment Purchase Fund (NTPF), as well as senior officials in the Department of Health.
Speaking after the meetings, he outlined actions being taken on waiting lists:
The moves follow an RTÉ documentary on waiting lists Monday.
It followed two children Darragh (7) and Megan (13) who suffer from scoliosis.
Darragh's condition has steadily deteriorated over the past year and the deformity of his spine has seriously encroached his lungs, making breathing difficult.
Megan's spinal curvature has worsened dramatically in recent times. She now finds it almost impossible to attend school.
In this clip Darragh's mother, Claire Cahill, says his life is made so much harder as a result of not receiving treatment.
Dr Pat Kiely is a children's orthopedic and spinal surgeon specialising in scoliosis.
He told Newstalk Drive earlier this has been an ongoing issue for the last decade.
"What we're talking about is directed and focused resources.
"In our country we'd expect that 200 young people would get scoliosis to the level where it needs surgical intervention.
"The vast majority of people do not need surgical intervention - but there is a number you can predict and that's been independently verified (at) about 200 kids a year.
"We never, in this country, had really a targeted or focused system to provide up to that volume of cases.
"So therefore when we were back in 2007 or thereabouts Crumlin used to provide surgery for 30 to 40 cases a year, but the volume that needed surgery was often one to two cases per week."
In the Dáil earlier, Taoiseach Enda Kenny denied the waiting list figures are being massaged.
He said they have been calculated the same way for 15 years.
And Mr Kenny said the focus of the Government's efforts will be to ensure no further delays in scoliosis surgeries.
"The focus will be - will be as you request - quite rightly on the issue of scoliosis.
"So that no child will be left with the challenges and the difficulties and the pain that they are left in.
"It's not acceptable.
"(But) the problem is how do you get your theatre, which they taxpayer paid for, open and giving relief and comfort to children who have this particular problem?", he added.
