Clinical Trial: Characterization of the Charcot Foot

Study Status: Enrolling by invitation
Recruit Status: Enrolling by invitation
Study Type: Observational

Official Title: Follow-up on Cross-sectional Study of Known Population With Charcot Osteoarthropathy - Metabolic, Physiologic and Pathologic Changes

Brief Summary:

The project concerns a type of very debilitating diabetic foot complications called Charcots osteoarthropathy (COA). This disease is characterized by a rapidly progressing destruction of the load bearing joints, primarily in the feet, resulting in loss of structure and remodeling. Untreated this cascade leads to the collapse of the bones, meaning severe pain and walking disability for the patient. Reconstruction is often very difficult or impossible, and furthermore the collapse can lead to chronic foot ulcers and infections, which in the worst case can be fatal.

Treatment options are currently limited to early diagnosis and physical offloading (immobilisation), assisted wound healing and surgical intervention.

The purpose of this project is to investigate and describe the bone-related factors, which separate COA from other, less acute, diabetic foot changes. The investigators wish to describe the long term consequences of COA - both anatomically, physiologically and biochemically.

The investigators will be doing this in a follow-up investigations on a group of COA patients tested 8 years ago. Little is known of the long term changes to the bone structure after acute COA, and the investigators want to visualize to what extend the bone damage is permanent.

To do this the investigators will be using DXA-scans, x-ray, blood tests including bone markers, neurophysiological tests and occlusion plethysmography.
