The recovery ranges depending on the player but it is usually a minimum of nine months, although CA believes it will only take six months. That rules him out of the entire summer of cricket, which includes the five Tests against India, the tour of Sri Lanka and the Champions Trophy. The IPL, the World Test Championship final in June, if Australia make it, and the three-Test tour of the Caribbean in June and July of next year are possible given CA’s timeframe, especially as a batter only but bowling is a different story.

Scans had shown the fracture in the UK but further assessments were required back in Australia as it is understood to be a different fracture to his previous stress injuries. Green has previously had four stress fractures in his lower back, which were recurring through his junior days all the way up to 2019, a year prior to his Test debut.

CA’s medical staff are understood to be flummoxed by how this fracture has occurred after successfully managing Green through the past four years of international cricket, although he has always been vulnerable to another fracture given his history. CA released a statement outlining the reasoning for the surgery.

“Cam has a unique defect in an adjacent area to the fracture that is believed to be contributing to the injury,” the statement said. “After thorough consultation it was determined Cameron would benefit from the surgery to stabilise the defect and reduce the risk of future recurrence.”

He had a routine scan in August, something he does regularly, that showed up clear. That paved the way for him to bowl in the UK. He sent down 21.2 overs in the UK across five T20Is and two ODIs. The most he bowled in a match was the six overs at Chester-le-Street where he did deliver a barrage of short balls as Australia chased wickets, before pulling up sore.

There are conflicting views within Australian cricket over his loads in the UK considering how carefully Mitchell Marsh was managed by comparison with the India Test series in mind. Marsh only bowled four overs for the whole tour, and they came in the game after Green flew home.

But it is understood there were no indicators that Green was vulnerable in the lead-in and his bowling loads this year have been far lower than in 2021, 2022 and 2023. He bowled more than 230 overs in matches in 2021 and 2022, and 190 overs in 2023. But he had only bowled 124.3 overs to-date in 2024, albeit there were four Test matches to come for him. He was coming off a rare 10-week break from playing prior to the UK tour.

The particular surgery Green will have has been very successful for many players including Behrendorff, who underwent the procedure in 2019. CA team physio Nick Jones oversaw Behrendorff’s recovery in 2019-20 when he was with WA having done extensive research on the surgery and the recovery process.

ESPNcricinfo understands that the specific type of surgery has been performed on 26 patients over the course of nearly two decades by New Zealand-based surgeons Grahame Inglis and Rowan Schouten with 24 of them successfully returning to full fitness. New Zealand quick Kyle Jamieson is one of the unsuccessful ones so far but his specific case is understood to be very unusual and over the weekend Gary Stead said Jamieson was on track for a comeback during the Super Smash which starts in late December.

Dwarshuis had the surgery in 2019 and was back bowling in grade cricket just seven months later and played domestic cricket within 10 months. He has played first-class cricket in the years since but has only appeared in nine red-ball matches.

Behrendorff had surgery in October 2019 and did not play until December 2020. He has not returned to play first-class cricket but has had no real problems with his back since then.

Pattinson took 12 months to return to first-class cricket and it was another 22 months before he played Test cricket, although he had been out of the Australian set-up for 18 months prior to the surgery due to his injury issues. He retired from professional cricket at just 32 as his body wilted.

Henry had the surgery in 2012 when he was just 20 years old. His recent success against Australia in Test cricket earlier this year as a 32-year-old is an indicator of the long-term success that can be had.
