[Clinical observation on plate on the metatarsal side to reconstruction of tarsometatarsal joint dislocations secondary to diabetic charcot foot].

OBJECTIVE: To evaluate clinical results of plate on the metatarsal side to reconstruction of tarsometatarsal joint dislocations secondary to diabetic charcot foot.

METHODS: Seven patients (9 feet) patients with tarsometatarsal joint dislocations secondary to diabetic charcot foot were treated with plating from April 2012 to December 2014. All patients were male, and 5 cases were on the unilateral side and 2 cases were on the bilateral sides. The age of patients ranged from 45 to 52 with an average of 48 years old. The history of diabetics was from 6 to 15 years. X-ray and CT were used to evaluate fractures healing,and AOFAS was applied to estimate recovery of joint function.

RESULTS: All patients were followed up from 12 to 24 months with an average of 19 months. All incisions were healed at stage I . No infection, loosening and breakage of internal fixation, bone nonunion were found after operation. According to postoperative X-ray and CT results, the time of fracture healing ranged from 10 to 20 weeks with an average of 16 weeks. Six feet got excellent results, 2 good and 1 moderate based on AOFAS scoring.

CONCLUSION: Tarsometatarsal joint dislocations secondary to diabetic charcot foot treated with plate on the metatarsal side could obtain stable fixation and got satisfied early clinical results.
