Although diabetes and peripheral neuropathy are perhaps the most important risk factors for neuropathic osteoarthropathy, we hypothesized that peak plantar pressures may also be higher in patients who have this condition. We are unaware of any reports in the medical literature that have specifically addressed this hypothesis. We obtained data from the medical records of 164 diabetic patients who had been managed in a multidisciplinary tertiary-care diabetic foot-specialty clinic. We then divided the patients into four groups: those who had acute Charcot arthropathy, those who had neuropathic ulceration, those who had neuropathy without ulceration, and those who had neither neuropathy nor ulceration. The peak plantar pressures were significantly higher in the patients who had acute Charcot arthropathy and those who had a neuropathic ulcer (p < 0.001 for both) compared with the pressures in those who had no history of arthropathy and those who had neuropathy without ulceration. With the numbers available, we could not detect a significant difference in the peak pressure between the affected and the unaffected foot in the patients who had Charcot arthropathy (mean [and standard deviation], 100+/-8.5 compared with 101+/-9.6 newtons per square centimeter; p > 0.05). However, the mean peak pressure was significantly higher on the ulcerated side than on the contralateral side in the patients who had a neuropathic ulcer (90+/-18.8 compared with 86+/-20.7 newtons per square centimeter; p < 0.02). Although the midfoot was the site of maximum involvement in all patients who had Charcot arthropathy, the peak plantar pressure was on the forefoot, suggesting that the forefoot may function as a lever, forcing collapse in the midfoot.

Involvement of the ankle joint in Charcot osteoarthropathy may be associated with severe instability and fracture or collapse of the talus. Recalcitrant ulceration may result over the lateral malleolus, increasing the risk of major amputation. This study evaluated ankle arthrodesis with a compressive intramedullary nail in 14 patients with diabetes affected by Charcot of the ankle. The mean patient age was 58 +/- 12 years, and the mean duration of diabetes was 17 +/- 5 years. Transcutaneous oxygen pressures were > or = 50 mm Hg in all patients, indicating a good distal blood supply. A below-knee amputation had previously been suggested because of severe ankle joint instability. None of the patients were able to walk without a brace. Four patients had an ulceration that had healed before the index procedure. All procedures were performed in the quiescent phase of the disease. After a mean follow-up of 18 +/- 4 months, 10 patients (71.4%) achieved a solid arthrodesis, returning to walking with protective shoes. Three patients (21.4%) developed breakage of the calcaneus screws, necessitating removal of the screws in 2 cases and removal of the entire nail in 2 cases. These 3 patients went on to fibrous union that allowed walking with a brace. One patient (7.2%) required a below-knee amputation because of postoperative osteomyelitis of the distal tibia. The data from our study demonstrate a high rate of limb salvage (92.8%), suggesting that this device is safe and effective in the treatment of Charcot arthropathy of the ankle.

Medial column fixation for rocker-bottom deformity in Charcot arthropathy is commonly performed. However, implant failure is commonly encountered because of uncontrolled weight bearing by the patient. The aim of this case report is to describe the use of a large solid bolt for fusion of the medial column of the foot in a patient with collapse of the midfoot due to diabetic neuroarthropathy.

The Grand Rapids Arch Collapse classifications create a novel system for categorizing and correlating numerous common foot and ankle conditions related to a falling arch. The algorithm for treating these conditions is exceptionally replicable and has excellent outcomes. Gastrocnemius equinus diagnosis plays a crucial role in the pathology of arch collapse. A contracture of the gastrocnemius muscle is increasingly recognized as the cause of several foot and ankle conditions. The authors have expanded their indications for gastrocnemius recession to include arch pain without radiographic abnormality, calcaneus apophysitis, plantar fasciitis/fibromas, Achilles tendonosis, early-onset diabetic Charcot arthropathy, and neuropathic forefoot ulcers.
