Zusammenfassung
Eine Neuroosteoarthropathie geht mit einer schmerzarmen oder schmerzlosen Destruktion einzelner oder multipler Gelenke einher. Hauptrisikopatienten sind Diabetiker mit Polyneuropathie, der Hauptmanifestationsort ist der Fuß und die Sprunggelenksregion (Charcot-Fuß). Für die Entstehung sind insbesondere unbemerkte oder repetitive Traumata entscheidend. Unerkannt und unbehandelt können Frakturen, Dislokationen, erhebliche Fehlstellungen, Instabilitäten und Ulzerationen resultieren, die das Risiko eines konsekutiven Extremitätenverlusts durch die Notwendigkeit zur Amputation, in jedem Fall aber einer funktionellen Beschränkung erheblich steigern. Der frühen Diagnostik in der Akutphase kommt somit entscheidende prognostische Bedeutung zu. Die Primärbehandlung besteht aus vollständiger Druckentlastung und Ruhigstellung des Fußes bzw. der betroffenen Extremität, gefolgt von einer stadiengerechten Wiederaufnahme der Belastung bis zur Heilung. Die chirurgische Therapie ist als essenzieller Baustein bei der Behandlung von Komplikationen in jedem Stadium des Charcot-Fußes in das Gesamtbehandlungskonzept zu integrieren. Hauptindikationen einer chirurgischen extremitätenerhaltenden Therapie sind anderweitig nicht behandelbare Instabilitäten oder Deformitäten mit Weichteilproblemen im chronischen Stadium des Charcot-Fußes. Korrektureingriffe können somit einen relevanten Beitrag zum langfristigen Extremitätenerhalt und zur Mobilität und Lebensqualität des Patienten leisten.
Abstract
Neuro-osteoarthropathy is accompanied by the destruction of single or multiple joints involving little or no pain. Diabetic patients suffering from symmetric distal polyneuropathy are the main risk group. The main location is the foot (Charcot foot). Inadvertent or repetitive trauma appears to be the main trigger mechanism for Charcot foot. Undiagnosed and untreated fractures and dislocations, foot and ankle deformities and instabilities with consecutive ulcerations may be the consequence, which again may increase the risk for later extremity loss due to the need for amputation or at least functional deterioration. Early diagnosis in the acute phase is of the utmost importance for the patient’s prognosis. The primary strategy consists of unloading and immobilizing the foot and the corresponding extremity followed by stage-related protected remobilization until definite healing occurs. Surgical intervention is a key-stone in the treatment of complications at any stage. Surgery is an essential part of treatment and should be integrated into the overall treatment plan. The main indications for orthopedic reconstruction are non-plantigrade foot and ankle deformities or instabilities with concomitant ulcers that cannot be adequately addressed by non-operative measures, mainly in the chronic stage of Charcot foot. As such, surgical reconstruction can contribute to the long-term preservation of the affected foot and help to maintain or improve the patient’s mobility and quality of life.
