Sulzer Hip Implants

Lea en español

Sulzer Orthopedics recalled 25,000 Sulzer hip implants in 2000 because of a defect caused by a lubricant used during the manufacturing process of the Inter-Op acetabular shell. The device was designed to fit into place and allow the surrounding bone to naturally bond to it. It was found that the oil-based residue left during the manufacturing process interfered with the bonding process.

Sulzer Orthopedics ordered the recall after an eight-week investigation into patient records and the device itself. By the end of March 2001, 748 revision surgeries related to Sulzer hip implants had taken place. In 2002, a settlement proposal was reached with Sulzer for nearly $1 billion.

Side Effects

The possible side effects of this defect are in many cases attributed to the loosening of the Inter-Op acetabular shell. These side effects may require additional replacement surgery to correct the problem. Some side effects found in patients with defective implants include:

  • Severe pain in the thigh, groin or anterior trochanteric area
  • Increased pain accompanying increased weight-bearing
  • Migration
