Charcot neuroosteoarthropathy of the feet can induce severe instability and deformity with subsequent plantar ulceration leading to substantial disability or even amputation. Traditionally, nonoperative treatment is regarded as the primary option of treatment while surgery is restricted to treating complications or failure of nonoperative treatment. Failed nonoperative treatment essentially prolongs treatment period. We retrospectively reviewed 22 patients (26 feet) with midfoot (n = 9) or hindfoot (n = 17) neuropathy who underwent primary surgical reconstruction and reorientation arthrodesis due to manifest instability, nonplantigrade foot position, and deformity with overt (n = 8) or what we judged was impending ulceration (n = 9). The minimum followup was 0.5 years (mean, 2.7 years; range 0.5-7 years). All eight ulcers healed without recurrence of ulceration or manifestation of new ulcers during the followup period. We observed complications leading to further surgery in nine patients: five with perioperative hematoma and four with instability.

Retrospective methods of fracture registration do not provide sufficiently reliable data.

Symptomatic secondary osteoarthritis of the Lisfranc joints due to malunion following Lisfranc joint fracture dislocations or ligamentous lesions at the Lisfranc and innominate joint level generally lead to a painful functional loss and a substantial disturbance of the walking performance. Initially missed or inadequately addressed primary lesions still represent the major source of Lisfranc joint malunions. Neuro-osteoarthropathic disorders may also become manifest in the Lisfranc joint region and may be mistaken for truly posttraumatic consequences. Secondary osteoarthritis may be combined with typical multiplanar deformities. The concept of a corrective arthrodesis includes restoration of stable physiologic axes and length proportions of the foot columns. A standardized approach to analyze the clinical picture and corresponding pathomorphology and the transfer into a comprehensive surgical concept which respects the realignment of any component of deformity is a prerequisite for a good functional outcome and a high degree of patient satisfaction. A fusion limited to the medial three rays combined with a soft tissue release may be sufficient for a favorable outcome in the majority of cases and preserve the mobility of the two lateral rays.
