Why use cancellous screws?

Cancellous screws are mainly used for fixing of #CancellousBone. Mostly, the surgeons use these screws in metaphyses of long bones as cancellous bone is abundant in that region. A reason why cancellous screws are preferred is that these have threads that are more widely spaced and deeply cut. This is the reason that #CancellousScrews are preferred over #CorticalScrews.

Another reason is that cancellous bone is much less dense. Therefore, cancellous screws threads can cut their path in the bone easily. This is because these screws are self-tapping, which means that they can make their path on their own when the screw is pressed. Since cancellous screws are partially threaded, they are used as lag screw also for metaphyseal fractures. For more details please visit: https://tinyurl.com/y9g2rxnm ,https://tinyurl.com/ybx3o2fx
