The total of AERs for Pinnacle is 2,570 (450 have been confirmed to have a metal liner)
Aggregate Pinnacle Complaints Metal-on-Metal
The total number of Pinnacle implant AERs for 2011 is 1,265 (450 confirmed metal) The estimate is that DePuy is on track to have over 1,700 Pinnacle AERs as compared to 556 in 2010 and 315 in 2009 (271 com=nfirmed metal and 135 confirmed metal, respectively). the most recent data continues to show no apparent problems with polyethylene liners with only six AERs having been identified with a polyethylene liner.
A metal-on-metal version of DePuy Orthopaedic's Pinnacle Acetabular Cup System may be associated with premature failure and other complications. Our firm is currently investigating complaints regarding DePuy Pinnacle hip implant problems including severe swelling, disabling pain, loosening of the implant, and early failures that result in a need for revision surgery. If you have experienced complications following hip replacement surgery that involved the metal-on-metal version of DePuy Pinnacle Acetabular Cup System, we would like you to contact us immediately. Patients who experience failure of a metal-on-metal Pinnacle hip implant may suffer
- Loosening of the various components in the implant;
- Necrosis (premature death of body tissue) or soft tissue damage due to exposure to metal particles due to wear of the implant;
- Elevated cobalt and chromium levels in the blood due to wear of the implant.
- Severe pain in implant, radiating into the groin and/or back
- Radiographic changes including loosening and lysis (dissolution or destruction of cells) or osteolysis
- Fluid collections and cystic or solid masses around the joint
1. Patient with a failed total hip replacement with considerable proximal femoral bone loss, proximal migration of the greater trochanter and breakage of multiple screws distally from the previous interlocking device.
2. Surgeons revised the hip implant with a constrained acetabular component and cemented a proximal femoral replacement into the distal femur.

DePuy Pinnacle Hip Implant Complications
Broken head of hip implant (upper left) and pieces of broken ceramic material embedded into tissue (lower right) due to wearing of hip implant which may lead to Osteolysis and bone breakage.
The metal-on-metal version of the DePuy Pinnacle hip replacement consists of articulating surfaces are made from cobalt-chrome. This design purportedly offers high wear resistance and has much smaller debris particles than those with metal-on-plastic devices. However, metal-on-metal hip implants like the DePuy Pinnacle device are increasingly causing concerns.
1. A radiograph of the pelvis demonstrates area of wear of the acetabular liner, with superolateral displacement of the femoral head (red arrow). Large radiolucent area superior to the acetabular companent (yellow arrow), and bony resorption of the proximal medial femur adjacent to the insertion site of the femoral prosthetic companent (green arrow).
2. Changes not seen in first film.
According to the U.S. Food & Drug Administration (FDA), because the metal ball and the metal cup on these types of hip implants slide against each other during walking or running, some tiny metal particles may wear off of the device and enter into the space around the implant. Some of the metal ions from the metal implant or from the metal particles may even get into the bloodstream. It is known that over time, the metal particles around some implants can cause damage to bone and/or tissue surrounding the implant and joint. According to the FDA, this is sometimes referred to as an “adverse local tissue reaction (ALTR)” or an “adverse reaction to metal debris (ARMD).” Such a reaction may cause the implant to become loose or cause pain. Ultimately this can require a revision surgery where the old device is removed and replaced with another one," the FDA has said.
Some of the problems that have sparked the filing of DePuy Pinnacle metal-on-metal hip implant lawsuits include:
- Unexplained Hip Pain
- Difficulty Standing or Walking
- Loss of Mobility
- Loosening of a DePuy Pinnacle Hip
- Hip Replacement Failure
- Additional Hip Revision Surgery
1. Loose total hip replacement
2. Right hip revision hip replacement to correct loosened hip implant.
In 2010, the FDA's Adverse Event Reporting System received nearly 550 reports of problems in patients who had received a DePuy Pinnacle hip replacement. Many of those reports involved complaints of disabling hip and groin pain, doctors finding metal particles and signs of metallosis during revision surgery, and reports of acetabular cups moving out of position.
1. Osteolysis involves wear particles (worn off the contact surface of the artificial ball and socket joint). As the body attempts to clean up these wear particles (typically consisting of plastic or metal) it triggers an autoimmune reaction which causes resorption of living bone tissue. Osteolysis has been reported to occur as early as 12 months after implantation and is usually progressive. This may require a revision surgery (replacement of the prosthesis).
2. Aseptic loosening of a hip implant. Note the radiolucencies next to the implant, a result of osteolytic bone loss.
Despite numerous complaints regarding the metal-on-metal version the device, no DePuy Pinnacle hip implant recall has yet been issued.
