Commitments and Contingencies Disclosure [Abstract]
Contingencies and Commitments	CONTINGENCIES AND COMMITMENTS We are involved in various ongoing proceedings, legal actions and claims arising in the normal course of business, including proceedings related to product, labor, intellectual property and other matters that are more fully described below. The outcomes of these matters will generally not be known for prolonged periods of time. In certain of the legal proceedings, the claimants seek damages as well as other compensatory and equitable relief that could result in the payment of significant claims and settlements and/or the imposition of injunctions or other equitable relief. For legal matters for which management had sufficient information to reasonably estimate our future obligations, a liability representing management's best estimate of the probable loss, or the minimum of the range of probable losses when a best estimate within the range is not known, is recorded. The estimates are based on consultation with legal counsel, previous settlement experience and settlement strategies. If actual outcomes are less favorable than those estimated by management, additional expense may be incurred, which could unfavorably affect future operating results. We are self-insured for product liability claims and expenses. The ultimate cost to us with respect to product liability claims could be materially different than the amount of the current estimates and accruals and could have a material adverse effect on our financial position, results of operations and cash flows. In June 2012 we voluntarily recalled our Rejuvenate and ABG II Modular-Neck hip stems and terminated global distribution of these hip products. Product liability lawsuits relating to this voluntary recall have been filed against us. On November 3, 2014 we announced that we had entered into a settlement agreement to compensate eligible United States patients who had revision surgery to replace their Rejuvenate and/or ABG II Modular-Neck hip stem prior to that date and in December 2016 the settlement program was extended to patients who had revision surgery prior to December 19, 2016. We continue to offer support for recall-related care and reimburse patients who are not eligible to enroll in the settlement program for testing and treatment services, including any necessary revision surgeries. In addition, some lawsuits will remain and we will continue to defend against them. Based on the information that has been received, the actuarially determined range of probable loss to resolve this matter globally is currently estimated to be approximately $2,073 to $2,313 ($2,305 to $2,545 before $232 of third-party insurance recoveries). We did not recognize additional charges to earnings in the six months 2018 as the low end of the range of the liability was equal to the amount of previously recorded reserves. The final outcome of this matter is dependent on many factors that are difficult to predict including the number of enrollees in the settlement program and the total awards to them, the number and costs of patients not eligible for the settlement program who seek testing and treatment services and require revision surgery and the number and actual costs to resolve the remaining lawsuits. Accordingly, the ultimate cost to resolve this entire matter globally may be materially different than the amount of the current estimate and accruals and could have a material adverse effect on our financial position, results of operations and cash flows. In 2010 we filed a lawsuit in federal court against Zimmer Biomet Holdings, Inc. (Zimmer), alleging that a Zimmer product infringed on three of our patents. In 2013 following a jury trial favorable to us, the trial judge entered a final judgment that, among other things, awarded us damages of $76 and ordered Zimmer to pay us enhanced damages. Zimmer appealed this ruling. In December 2014 the Federal Circuit affirmed the damages awarded to us, reversed the order for enhanced damages and remanded the issue of attorney fees to the trial court. In May 2015 the trial court entered a stipulated judgment that, among other things, required Zimmer to pay us the base amount of damages and interest, while the issues of enhanced damages and attorney fees continue to be pursued. In June 2015 we recorded a $54 gain, net of legal costs, which was recorded within selling, general and administrative expenses. On June 13, 2016 the United States Supreme Court vacated the decision of the Federal Circuit that reversed our judgment for enhanced damages and remanded the case to the Federal Circuit to reconsider the issue. On September 12, 2016 the Federal Circuit issued an opinion that, among other things, remanded the issue of enhanced damages to the trial court. On July 12, 2017 the trial court reaffirmed its award of enhanced damages and entered a judgment of $164 in our favor. On July 24, 2017 Zimmer filed a notice of appeal of this decision.
