Rigid Cavus Foot Deformity

Rigid Cavus Foot Deformity

Overview
Pes cavus foot occurs in about 8% to 15% of the population, but it does not get nearly as much attention in the medical literature as does its counterpart, pes planus. Sixty percent of individuals with cavus feet develop foot pain.

Causes
The most frequent cause of cavus foot in children is a nerve or muscle disease. The condition usually is not present at birth but rather develops slowly during the first 10 years of life. Among cavus foot?s most common causes are Charcot-Marie-Tooth disease (CMT), Spina bifida, Polio, Muscular dystrophy, Injuries to the nerves in legs or spinal cord, Injuries to the leg muscles, Cavus foot also may be an inherited structural abnormality.'Pes

Symptoms
There are many symptoms believed to be related to the cavus foot. These include shoe-fitting problems, lateral ankle instability, lower limb stress fractures, knee pain, iliotibial band friction syndrome, back pain and tripping. Foot pain in people with pes cavus may result from abnormal plantar pressure loading because, structurally, the cavoid foot is regarded as being rigid and non-shock absorbent and having reduced ground contact area. There have previously been reports of an association between excessive plantar pressure and foot pathology in people with pes cavus.

Diagnosis
Knowing the underlying cause of cavus foot is important because it is likely to get progressively worse when it results from neurological disorders. When cavus foot is not caused by these disorders, it usually does not change in appearance. Orthopedic surgeons work closely with pediatric neurologists to discover the cause of a child?s cavus foot in order to treat any underlying disease.

Non Surgical Treatment
Careful investigation is needed to rule out any neurological condition that is causing the high arched foot. This will depend on what is causing the pain, if anything. For instance, flexible high arches may not need any treatment. Wear shoes with a good cushioning, depth and arch support. Control body weight to decrease load on the feet. Over-the-counter arch supports may be helpful for mild cases of pes cavus, but they are often a poor fit for persons with severe pes cavus.

Surgical Treatment
Surgery is a last resort if the above conservative measures fail to control symptoms. Surgery is only justified when deformity is so pronounced or progressive that symptoms are intrusive and unresponsive to conservative treatments. On the other hand, surgery should not be delayed so long that severe ulceration develops or the patient cannot ambulate. A timely, limited surgical intervention, while the foot is still flexible, How can you get taller in a week? re-balance the foot and prevent the need for a larger, more technically demanding procedure later on.'Supinated
