Yet another Stryker hip implant recall may be on the horizon. Last month, the Australian Department of Health issued a hazard alert, warning patients and healthcare professionals of the potentially defective Stryker hip implant components. Health Canada had already recalled the devices in August, 2016. The affected units are specific sizes of LFIT Anatomic CoCr V4·0TM Femoral Heads, manufactured prior to 2011. This is not the first time Stryker has had issues with defective hip implants. In 2014, the device maker agreed to pay more than $1.4 billion to settle claims over defective hip implants.

The Defect

The defective Stryker hip implant components affected at this time are certain sizes of the Low Friction Ion Treatment (LFIT) Anatomic CoCr V40 femoral head, manufactured before 2011. The femoral neck is inserted into the thighbone (femur), leaving the artificial femoral head protruding. The part that is failing is the taper lock, which connects the femoral head to the femoral neck.

Dangers associated with this defect include:

  • Pain
  • Inflammation
  • Noise, such as popping and squeaking
  • Insufficient range of motion
  • Loss of mobility
  • Insufficient soft tissue tension
  • Joint instability
  • Dislocation
  • Separation of the femoral head from the hip stem
  • Fractured hip stem trunnion
  • Increased metallic debris
  • Increased polymeric wear debris
  • Cobalt or chromium toxicity and poisoning
  • Metallosis
  • Adverse local tissue reaction
  • Tissue death (necrosis)
  • Broken bones around the components
  • Bone chipping or fracture
  • Bone loss
  • Loss of implant
  • Leg length discrepancy
  • Need for revision surgery

Prior Recalls

In 2011, the Accolade TMZF Plus Hip Stem was recalled due to a defect caused by employee error. In 2012, Stryker recalled its Rejuvenate and ABG II modular-neck stems due to fretting and corrosion at the modular neck junction, which can lead to metallosis.
