A common cause of anterior impingement is a bone spur on<unk> bone (talus) or the shinbone (tibia). Repeated kicking actions can cause the<unk> bone to hit the bottom of the shinbone, which can lead to a lump of bone (or bone spur) developing. This bone spur may then begin to impact on the soft tissue at the front of the<unk> , causing inflammation and swelling. The condition is most common in athletes who repeatedly bend the<unk>  upward (dorsiflexion), such as<unk> s, hence the name.
