The Philadelphia Trunnionosis Study
A study in the Journal of Bone and Joint Surgery has identified five cases of catastrophic trunnion dissociation in Stryker Accolade TMZ Femoral Hip Stems. In a small percentage of patients with certain risk factors, the hip implant device may fail painfully approximately 7 to 7.5 years after surgery.
The Accolade TMZ Femoral Hips at issue in the study were available for use from 2001 to 2011. In the patients experiencing failure, the adverse event was clustered around 7 to 7.5 years after surgery. It is believed that severe corrosion led to the dissociation of the femoral head from the trunnion. In addition to the five patients identified, the journal article mentions two previously known cases of catastrophic trunnion dissociation in total hip arthroplasty.
The typical patient who might suffer this problem after modular total hip arthroplasty is male, taller than 5 ft 10 inch and weighing greater than 180 pounds. It is estimated that this demographic puts greater load on the femoral head-trunnion interface. The patient group explored had cobalt-chromium alloy femoral heads combined with a titanium trunnion.
The Australia LFIT Alert
Australia has issued a hazard alert for certain femoral heads used in hip replacement surgeries. Specifically, a range of LFIT Anatomic CoCR V40 femoral heads manufactured by Stryker before 2011. Australia, in consultation with Stryker Orthopaedics, expressed concerns about a higher than expected incidence of taper lock failures (another name for trunnionosis).
The taper lock connects the femoral head to the femoral neck. If it fails, a patient can experience broken bones, joint instability, pain, inflammation, loss of mobility, leg length discrepancy and the need for revision surgery.
The impacted component was used in the Stryker Accolade TMZF, Accolade 2, Meridian and Citation hip implants. The Australian alert urged orthopedic surgeons to monitor patients with the component at issue for fractured hip stem trunnion, increased metallic debris, bone fixation strength, and disassociation of the femoral head from the hip stem.
Some legal commentary in the United States is already suggesting that a recall by Stryker is imminent. Stryker has already recalled other lines of its metal-on-metal hip implants due to complaints of inflammation, metal poisoning, inflammation and organ damage. Stryker is expected to pay out more than $1 billion total to plaintiffs in the previous litigation.
