[Lower limb orthosis to relieve stress forces on the foot and its use in patients with diabetic neuropathic osteoarthropathy: Case examples]

Abstract

In the daily routine of treating patients with diabetic neuropathic osteoarthropathy (DNOAP), their history often reveals a prolonged course of therapy caused in part by incorrect diagnosis but also by inadequate provision of orthopedic devices. A "classic" case is that of undetected osteoarthropathy, which is erroneously interpreted as osteomyelitis. Thus, subsequent to frustrating attempts at therapy and persistence of the clinical symptoms, patients are not infrequently "offered" the option of amputation, which is performed quite proximal to the osseous lesion to "ensure treatment success." The fact that major amputations lead to a statistically significant decrease of the patient's life span is usually not taken into consideration during the decision making process for amputation. Orthopedic surgical procedures to preserve the leg should be given precedence for the sake of maintaining quality of life just as orthopedic devices and orthopedic shoes should be preferred to retain mobility before amputation is indicated in patients with DNOAP. The cases reports presented here should encourage others to implement treatment concepts with the aim of avoiding unnecessary amputations.
