Medically, a dorsal bunion is termed hallux limitus or hallux rigidus, literally meaning limited or a lack of motion in the big toe. As with the common bunion, causes of a dorsal bunion involve an inherited biomechanical deformity that becomes worse with trauma and standard wear & tear. In early stages, motion of the big toe becomes limited, along with transient pain that gets worse with movement. At this point, the disorder is considered hallux limitus, since movement is only limited. Eventually, it becomes increasingly harder to bend the toe, and the pain becomes more severe; this is when disorder becomes hallux rigidus.
Needless to say, this disorder can be very troubling since we use our big toes whenever we want to walk, climb, or even stand. Because of this, it is important to get a diagnosis as early as possible. If you wait too long there is the likelihood of developing bone spurs, which make treatment more difficult to manage. If you are unsure, a simple appointment with a bunion removal doctor will point you in the right direction.
Fortunately, there are a variety of treatment options for hallux rigidus correction that are similar to treatments for the common bunion. For less severe cases, orthotic devices & over-the-counter medication can be used. In more severe cases, injections may be used in with physical therapy to reduce the symptoms and improve range of motion. For very severe cases, hallux rigidus surgery is a promising option that can be customized to your unique condition.
