Abstract
Diabetic foot syndrome with osteomyelitis of metatarsal head show frequent recurrence and need a very long antibiotic treatment, often only to see the inflammation flare up once antibiotic are dismissed.
We present our initial experience about 3 patients presenting a clinical and radiologically confirmed osteomyelitis of the metatarsal head. We treated them with limited resection of metatarsal head, microbiologic sample and filling of the remaining metatarsal canal by means of an absorbable antibiotic loaded bone graft substitute, packing an absorbable antibiotic sponge (Gentamycin) in place of the metatarsal head and direct skin closure. All patients had an orthesis avoiding fore-foot weight bearing during the first month, but allowing them to walk normally. Follow up took place on a weekly rhythm during the first month, every fortnight during the 2° month and after this once a month. Actually the follow up period extends from 4 – 7 months.
None of the treated 3 patients did need any second look operation nor did they present any local complications. Due to the type of resorbable implant used, some oozing of transparent liquid during the first 4 weeks may present and is to be considered normal.
This new method presents a valid alternative to the more classic “two step cement nail” procedure of active osteomyelitis treatment. We consider planing long term study and a multicenter randomized trial.
