The Wright Pro Femur and Conserve Plus hip replacement systems have been associated with reports of early failure and femoral neck fracture. The Conserve Plus is a metal-on-metal hip, which may release metal particles into the hip joint and surrounding tissue, resulting in a condition called metallosis.
Hundreds of adverse event reports have been submitted by Wright Conserve hips, and according to data from the 2008 annual report issued by the Australian National Joint Replacement Registry, the Wright Profemur Hip had a cumulative revision rate of 11.2% at three years. This particular hip device has a modular stem with two parts, which was expected to improve efficacy, but seems to be failing at an unacceptable rate. These types of devices are supposed to last 15 years.
The Wright Conserve Cup is similar in design to the DePuy ASR Cup, which was recalled in August 2010, after reports of numerous failures. It has been suggested that both devices are prone to early failure and metallosis.
In similar circumstances involving other hip implants, the FDA has issued mandatory recalls. In fact, the FDA’s adverse event reporting database indicates that there have been 10 failures of the Pro Femur Z Stem.
A 2011 lawsuit filed against Wright claimed that the Wright Profemur hip broke during regular activity and required painful revision surgery three years following its implant. According to the suit, the hip implaint is designed to be adjusted according to the patient’s leg length thereby allowing the system to bend easily. However, this feature also seems to be the cause of the increased risk of failure. The Wright Profemur Total Hip System includes the Conserve Plus, Cup, the Conserve Total Femoral Head, the Wright Modular Femoral Neck and the Profemur E Cementless Stem.
