Filling Bone Defects with Trabecular Metal Augments

When we face bone defect, it needs to be filled up else the implant will not last long. In past we used to harvest bone from some other part of patient’s own body. This would mean, one more operation. Many a times this bone may not be strong enough to support or it may get absorbed over a period of time, leaving the implant unsupported again.

With introduction of trabecular metal, we no more need to harvest bone from the patient’s body. Trabecular metal is tantalum, it mimics the structure of the bone, is strong and allows the bone to grow in its crevices thus getting integrated in body giving solid support

It comes in various shapes and sizes, making its use easy

Here are some pictures of Trabecular metal augments used in hip reconstruction

Case Hip Replacement for Childhood hip disease

This is the story of a 50 years old lady.

She was born with abnormal right hip.

As a child she was in and out of the hospital for multiple operations to correct her hip defect

Due to multiple operations her hip did not grow properly
As she grew up, her leg became short due to bad hip. This leg length inequality led to wear and tear in the opposite knee requiring replacement

She became wheel chair bound due to pain in her right hip and short leg

Her case being complex, it was decided to make a 3D printed bone model of her hip to plan the surgery
Since it was found that the artificial cup of hip replacement would not have adequate bone support, it was decided to use trabecular metal augment to fill the defect
During surgery the same steps were carried out. Trial fit on bone model made the surgery easy and perfect fit was achieved on the table
She also needed correction of her thigh bone (Femur)
Post surgery I could make the hip painless and length of the limb almost equal to the opposite

Now she is out of wheel chair and able to walk with support of a walking stick
