Carl Pistorius on the road to recovery
Pistorius suffered lacerations to his heart and liver and went into respiratory failure after a car crash.
The Paralympic and Olympic athlete's older brother was driving back from Limpopo two weeks ago when another vehicle allegedly swerved in front of him, causing the collision.
While Carl was discharged last week, family spokesperson Anneliese Burgess says he faces at least another two weeks in hospital and more operations.
She says Carl suffered lacerations to his heart and liver and went into respiratory failure.
Carl, who has been a pillar of support for the athlete during his murder trial, was unable to attend the closing arguments because of the crash.
Burgess says once Carl is discharged, he will be sent to a rehabilitation facility to regain his mobility.
In 2008, Carl was involved in a collision with a motorcyclist who died and was later acquitted of culpable homicide.
Judgment in Pistorius's murder trial is scheduled to be handed down on 11 September.
The Blade Runner is on trial for the murder of his model girlfriend Reeva Steenkamp who was shot dead at his luxury Pretoria East home on Valentine's Day last year.
The 27-year-old athlete maintains he shot the 29-year-old by accident, believing she was an intruder but the state has argued it was premeditated murder.
Pistorius also faces three separate charges, including two counts of discharging firearms in public and possession of illegal ammunition, all of which he denies.
Judge Thokozile Masipa has more than 4,000 pages of evidence to review.
The athlete broke down frequently during the trial, often sobbing and vomiting into a bucket.
Steenkamp's dramatic death has shattered the image of Pistorius as an embodiment of triumph over adversity for both his Paralympic victories and his success against able-bodied athletes at the 2012 London Olympics.
