The field of prosthetics involves the design, fabrication, and fitting of artificial limbs (prostheses) to replace a part of the body that has either been lost through amputation or was absent at birth. We design, fabricate, and deliver state-of-the-art, lightweight, custom fabricated prostheses tailor-made for each individual’s specific needs. We provide initial training with each prosthesis and routine follow up care to ensure the best the possible outcome. We establish long term relationships with our patients as we continue to service their prosthetic needs for years to come.

The field of orthotics involves the use of braces (orthoses) to support, assist, or protect specific areas of the body that have been weakened or damaged by birth defects, accidents, or disease. We routinely treat patients who have been affected by CMT, polio, cerebral palsy, stroke, muscular dystrophy, multiple sclerosis, or spinal cord injury. Our treatment includes evaluation, measurement and/or casting of the affected part of the body. An orthosis is then designed according to the physician’s prescription or the orthotist’s recommendation to the physician based upon the evaluation. Every orthosis is either custom made or custom fitted to provide the most effective treatment possible for the specific condition that is being addressed. At the time of delivery you will be given specific application and use instructions for your particular device.

•Foot orthoses and arch supports
•Supramalleolar orthoses (SMO’s) for foot and ankle support
•Ankle foot orthoses (AFO’s) for foot, ankle, and knee stabilization
