Christopher Duntsch (pictured), 46, has been sentenced to life in prison for seriously injuring an elderly woman in a botched spine surgery in Plano, Texas

A jury has sentenced a former North Texas neurosurgeon to life in prison for killing two patients and maiming others who had turned to him for surgery to resolve debilitating injuries.

The decision came Monday afternoon, almost a week after the Dallas County jury convicted 46-year-old Christopher Duntsch of first-degree felony injury to an elderly person.

Duntsch was the first doctor in Dallas County to be convicted for a surgery gone wrong, District Attorney Faith Johnson said in a news conference after the sentencing Monday.

'We have done something historic here', Johnson said.

Prosecutors alleged numerous cases of malpractice against the former Plano physician, including that he improperly placed screws and plates along patients' spines, left a sponge in another patient and cut a major vein in another.

One of his victims, Jerry Summers, who he had known since they were children, woke up after undergoing spinal surgery at Baylor Regional Medical Center of Plano unable to move his arms or legs, according to the Dallas Morning-News.

The charges stem from incidents where Duntsch (left and right) is accused of causing the death of two patients, while mutilating four others - including Jerry Summers, who woke up after undergoing spinal surgery unable to move his arms or legs

Summers said in a video testimony played in court earlier this month: 'I don't remember feeling any pain, I just couldn't move.

'It just feels like your body weighs about 10,000 pounds and you can’t pick it up'.

In the video, which was shot in January in Summers's Memphis, Tennessee, home so he did not have to travel to Texas for Duntsch's trial, he then demonstrated how he is still unable to move his arms or legs.

Summers's 'botched' surgery took place in February 2012, after Duntsch had offered to perform the basic procedure to rid him of pain and numbness he had in his arm as a result of a previous car crash.

However, the surgery did not go according to plan, with the anesthesiologist who put Summers under revealing he lost more than 10 times more blood than usual during the operation.

Summers now suffers from incomplete paralysis - meaning he is unable to move his arms and legs, but still feels pain and touch.

Later in the same year, Duntsch operated on Kellie Martin.

Martin bled out and died after the doctor cut through her spinal cord, slashing a major artery, prosecutors allege.

Surgical nurse Catherine Kelly-Lorenz, who was involved with Duntsch for the deadly surgery, said the disgraced surgeon did not seem concerned with what had happened - despite the fact Martin was 'screaming in pain' when she first woke up and had to be put back under.

Another of Duntsch's patients, 63-year-old Floella Brown, also died in July 2012.

Brown suffered a stroke after she underwent spinal surgery, in which the Texas Medical Board found the doctor 'went overboard'.

Records state Duntsch removed 'bone from an area that was not required by any clinical or anatomical standards, resulting in injury to the vertebral artery'.

Another female patient, Mary Efurd, testified in court last week about injuries she suffered allegedly at Duntsch's hands during another 2012 surgery when she was 74.

During the surgery to help fix her back pain, Efurd lost a half-gallon of blood and the use of her legs, the Dallas Morning-News reports.

'I trusted him, I trusted he would do what was right,' she told the court earlier this month.

Duntsch has his license revoked in 2013, despite him claiming at the time: '99 per cent of everything that has been said about me is completely false'.

The medical board cited abuse of care with six patients when they revoked his license.

A surgeon testifying for prosecutors said it was like letting an amateur loose in surgery.

'The pain won’t go away for [the victims]', Johnson, the district attorney, said Monday.

'But we hope they will just have a little joy to know that the person that did this thing to them will be serving a life sentence'.

Duntsch's attorneys argued he wasn't a criminal, just a lousy surgeon.

An affidavit revealed that in an email from December 2011 Duntsch outlined a desire to inflict pain upon his patients.

'I am ready to leave the love and kindness and goodness and patience that I mix with everything else that I am and become a cold blooded killer', he wrote to an employee.
