Brussels: Former women's world number one Justine Henin of Belgium retired for the second time on Wednesday, citing an elbow injury that had dogged her since last summer.

"Today, the (medical) examinations are clear and the doctors are agreed that my elbow is too damaged for me to be able continuing with my passion and my job at a high level," Henin said on her internet site.
Henin, 28, first laid down her racket in May 2008 having won seven Grand Slam singles titles, including four French Open titles, one Australian Open title, and two US Open titles.

On that occasion she said she simply wanted to step back from the professional game having spent 100 weeks as world number one, which was her ranking at the time she first hung up her racket.

She quit first time round just two weeks before making another defence of the French Open crown which she had won for the previous three seasons, after her opening success at Roland Garros in 2003, her first Slam crown.

Henin returned in Brisbane at the start of last year having rediscovered her appetite for the tour and reached the Australian Open final.

But this season has been a difficult experience as she lost at Melbourne in the third round to Russia's Svetlana Kuznetsova.

Entering 2011, Henin had not played a tournament since suffering a career-threatening right elbow injury when losing to compatriot Kim Clijsters in the fourth round at Wimbledon in late June.

During the Hopman Cup, prior to Melbourne, Henin, who has won an overall 43 singles titles - including the 2004 Olympic title - admitted there were times when she did not think she would be fit to play this year's Australian Open.

She added she was suffering pain in the elbow, especially during her service motion.

Even though she impressed at the Hopman Cup she said she had to listen to the doctors.

"After due reflection and following doctors' advice the time has come to face up to the evidence and accept that this is the definitive end of my career. But it's hard, very hard, as I came back with such desire."

After her Australian exit, Henin went straight home to Belgium for tests and bowed to the inevitable.

"This time it's for good - I am turning an incredible page of my life," Henin said.

She admitted that she was "going through some difficult moments" having realised ever since Wimbledon that her return to action was likely to be short-lived.

In recent months, she said the spectre of the injury had weighed ever more heavily.

"Time has passed and the doubts have grown. And only return to the courts would give me answers - not the answers I was hoping for, unfortunately.

"I did everything I could to get over the injury - (but) I was rarely spared from pain. I have suffered more and more every day these past weeks."

Nonetheless, she insisted that she was pleased, despite her fitness trials and tribulations, to have made the effort to return, saying she had learned a lot over the past 15 months.

"Today, I'm calmer and I can create a positve and rewarding look back on this experience in my life."

She admitted: "Of course I am in shock - I am sad. I had hoped for a different kind of return and a different ending."

Even so, she concluded that despite her sadness at having to recognise her career was over, it had still been "a wonderful journey.

Now it was time, she said, to embark on "new adventures," without giving any further details.
