Study summary

Randomized clinical trial (RCT) to compare treatment failure rates of surgical arthrodesis with MFB against cast treatment in patients suffering from early stage Charcot neuroarthropathy (CN) of the midfoot (Sella and Barrette stages 0, 1 or 2) within the first 2 years after initial treatment. Treatment failure is defined as the occurrence of one or more of the following: 1. Amputation, 2. Occurrence of ulcer or worsening of existing ulcer, 3. Surgical intervention for correction of deformity after initial treatment. The secondary aims are to compare foot function, radiologic outcome, quality of life, complications and foot temperature between the two groups.

What researchers measure

Primary outcomes

  1. treatment failure rate

    Treatment failure is defined as the occurrence of one or more of the following: 1. Amputation 2. Occurrence of ulcer or worsening of existing ulcer (according to Wagner classification) 3. Surgical intervention for correction of deformity after initial treatment

    Time frame: baseline, 3 weeks, 6 weeks, 12 weeks, 6 months, 12 months, 24 months

Secondary outcomes

  1. Foot function

    Foot and ankle ability measure score and standard Range of motion measurements.

    Time frame: baseline, 3 weeks, 6 weeks, 12 weeks, 6 months, 12 months, 24 months

  2. Radiologic outcome

    Weightbearing or simulate lateral and AP x-Rays of both feet will be taken. Talus-first metatarsal and Calcaneus-fifth metatarsal angle will be measured.

    Time frame: baseline, 12 weeks, 12 months

  3. Evaluation of the generic quality of life including mobility, self-care, usual activities, pain/discomfort, and anxiety/depression

    EuroQoL5 questionnaire

    Time frame: baseline, 3 weeks, 6 weeks, 12 weeks, 6 months, 12 months, 24 months

  4. Rate of complications

    Time frame: baseline, 3 weeks, 6 weeks, 12 weeks, 6 months, 12 months, 24 months

  5. Foot temperature

    Diabetica Solutions thermometer

    Time frame: baseline, 3 weeks, 6 weeks, 12 weeks, 6 months, 12 months, 24 months
