Hallux Limitus is defined as a
deformity of the first metatarsophalangeal joint
(1st MPJ) or bunion joint,
that restricts the range of motion and often causes pain in the joint. Normally,
the range of motion is about 60 degrees.
With hallux limitus, there can be a little as no motion in the joint.
Often there is significant arthritis associated with the 1st MP joint, which is
clearly visible on x-ray.
There are several common causes of hallux limitus.
One cause is simply a gradual deterioration of the joint due to age. There
could be a history of trauma to the foot or joint, which may have begun the
deterioration of the joint years before. Sports injuries or dropping a heavy object on
the foot can cause the problem.
Different grades of the deformity exist from mild to
severe, with the amount of joint motion typically decreasing over time. Patients with
hallux limitus usually exhibit pronated or flat feet during gait and stance.
Orthotics
For Hallux Limitus
Orthotics
are an
important conservative therapy for hallux limitus because an orthotic can help control the abnormal pronatory forces that are created during gait. Orthotics can serve as an alternative
treatment to surgery during the early stages of hallux limitus. Orthotics also can act as a
postoperative tool to limit the biomechanical influences that caused hallux limitus,
thus reducing the chance of reoccurrence of symptoms.
Surgical
Options for Hallux Limitus
When the
conservative option of using orthotics is ineffective, then surgery should be
considered. The surgical procedure consists of a specialized type of
bunionectomy procedure, where the abnormal and arthritic portion of
bone of the bunion joint is removed and it is replaced by an implant or plastic
joint. The procedure is called a "bunionectomy with an implant." The bunionectomy with
implant procedure is much easier than a common hip joint replacement, and takes
approximately 40 minutes. Patients can walk on the foot, using a
special surgical shoe, immediately after the surgery, without crutches,
walkers, or a cast.
