Smith & Nephew Hip Replacement Lawsuits

People from across the U.S. have filed lawsuits over several models of Smith & Nephew’s hip-replacement implants. More than 400 of those lawsuits have been combined in a major federal litigation and more lawsuits are expected to be added to it.

UPDATE: As of September 2018, the number of lawsuits involving Smith & Nephew hip replacements was still growing. Drugwatch’s legal partners are still accepting Smith & Nephew hip cases.

People have reported higher-than-normal adverse events with several Smith & Nephew hip implant models. In 2017, the U.S. Judicial Panel on Multidistrict Litigation combined several lawsuits over Smith & Nephew’s Birmingham Hip Resurfacing (BHR) hip implants in a Maryland federal court.

Smith & Nephew issued a field-safety notice on its BHR implants in 2015, saying the devices posed a risk of dislocation, fractures and other complications that could require surgery to correct. In addition, the UK-based company recalled its R3 Acetabular Hip Systems in 2012 and its Modular SMF and Modular Redapt Revision in 2016, over issues serious enough to spark more potential lawsuits.

Status of Smith & Nephew Hip Replacement Lawsuits

Lawsuits over Smith & Nephew’s BHR hip implants are in the very early stages. There have been no trials, verdicts or settlements in the BHR cases yet. Attorneys are still taking cases and considering options for people affected by Smith & Nephew’s Modular SMF and Modular Redapt Revision Femoral Hip following recalls of those devices in 2016.

The first 28 lawsuits over Smith & Nephew’s Birmingham Hip Resurfacing (BHR) hip implants were combined in a multidistrict litigation (MDL) in Maryland federal court in April 2017. As of September 2018, a total of 442 lawsuits were pending in the MDL.

MDLs allow consolidating several similar lawsuits to pool resources and reduce duplication. This allows lawsuits to move more quickly through the legal process.

Why People have Sued Over Smith & Nephew Hips

People who have filed hip replacement lawsuits against Smith & Nephew claim the complications they suffered were due to the devices’ design.

The implants named in lawsuits are metal-on-metal hips. That means a metal ball fits into a metal socket to form the replacement joint. Wear caused by these two metal parts rubbing against one another releases microscopic amounts of metals that can lead to serious complications from damage to the body to implant failure.

Injuries Claimed in Smith & Nephew Hip Lawsuits
  • Device loosening
  • Dislocation of the implant
  • Metallosis or metal poisoning
  • Additional surgeries

Smith & Nephew Class Action Lawsuits

There are currently no class action lawsuits over Smith & Nephew hip implants. Problems with medical devices are usually handled through individual lawsuits.

If enough people file lawsuits over similar problems, their attorneys will sometimes seek to have the cases combined into a multidistrict litigation (MDL). MDLs, like class actions, allow plaintiffs to combine their resources. They also have other benefits in medical device cases.

Some Differences between MDLs and Class Action Lawsuits

Multidistrict Litigation (MDL)
  • U.S Judicial Panel on Multidistrict Litigation determines if several, similar lawsuits can be combined in a single MDL
  • MDLs can only be tried in federal courts (though some states have similar consolidated lawsuit methods
  • Each plaintiff is likely to see very large settlements or verdicts if they prevail in court
  • Settlement amounts or jury awards may vary depending on the plaintiffs’ individual injuries
Class Action Lawsuits
  • Court considers “class certification” to determine if lawsuit can be a class action
  • Class actions can be filed in state or federal court
  • Amount of any potential award must be so small it would not be worth pursuing an individual court case
  • Everyone who joins the class action receives a proportionate share awards or settlements
