Stroke Caused by Neck Manipulation
Triggers Ambitious Lawsuit

Stephen Barrett, M.D.

In 2008, a Canadian woman who was paralyzed by a neck manipulation filed a class-action lawsuit intended to stop inappropriate chiropractic manipulation and force Canadian regulators to deal with this problem. The suit, which is seeking more than $525 million in damages, targeted Alberta chiropractors who provide inappropriate spinal manipulations and regulators who have failed to curb their use. The plaintiffs are Sandra Nette and her husband David.

Stroke from chiropractic neck manipulation occurs when an artery to the brain ruptures or becomes blocked as a result of being stretched. The vertebral artery is vulnerable because it winds around the topmost cervical vertebra (atlas) to enter the skull, so that any abrupt rotation may stretch the artery and tear its delicate lining [1]. The lawsuit claim document states:

Slight use of her right arm enables Sandra to use a computer keyboard to communicate through a voice synthesizer. Her plight is readily apparent in videos posted to YouTube [3].

In addition to litigating on their own behalf, the Nettes asked court to permit them to represent all persons who paid for or received spinal manipulation (other than spinal manipulation to treat a diagnosis of acute or sub-acute uncomplicated back pain) from an Alberta chiropractor during the past decade. They also wanted to have Stiles represent a class of Alberta chiropractors who provide inappropriate manipulation.

The lawsuit named three defendants:

In 2008, Stiles's Web site stated:

The suit charges that Stiles misrepresented the benefits and failed to adequately disclose the risks of spinal manipulation. The plaintiffs' lead lawyers are Daryl Wilson, Q.C. and Philip Tinkler, Esq., of Fraser Milner Casgrain LLP, one of Canada's largest law firms. In 2006, Tinkler, who heads the firm's Edmonton class-action group, negotiated a $100 million settlement in a suit against the Government of Alberta [5].

Course of the Lawsuit

After further examination of the facts, the Spa and its owners were voluntarily dismissed as a defendant. In July 2009, the Alberta Court of Queen's Bench concluded that the Ministry of Health did not owe a private duty of care to individual citizens and dismissed it as a defendant [6]. In January 2010, the court dismissed the ACAC after concluding that (a) it did not owe a private duty of care to individual citizens and could not be held responsible for the conduct of its members, and (b) disputes about false claims by the association would be a matter for review by the legislature rather than the courts. The court also refused to certify the suit as a class action [7]. The malpractice suit against Stiles was settled with undisclosed payment in 2012 [8].
