Abstract
The purpose of this study is to present the surgical and functional results of a partial and total calcanectomy procedure as a foot salvage alternative in patients with extensive chronic osteomyelitis of the calcaneus.
Material: A retrospective review identified 19 calcanectomies in 16 patients: 5 partial, 11 total and 3 partial to total. The primary diagnosis was insulin-dependent diabetes mellitus (3 patients), neurophatic ulceration (2 patients), infected osteosynthesis (4 patients) and open fracture (7 patients). The average age of the patients was 42.36 years (range from 22 to 60). Prior procedures included removal of osteosynthesis, debridement, Gaenslen’s procedure and skin grafting. Operation was based in Martini’s technique. Most common bacteria were Staphylococcus aureus. Antibiotic treatment was based in cultures and has changed during this period of time.
Results: Four patients were lost (2 died) and the rest average follow-up was 9.8 years (range from 1 to 19 years). Recurrence of infection was present in 3/5 partial calcanectomies and in 1/14 of total calcanectomies. Talonavicular subluxation occurred as a late complication in the patient with recurrence after total calcanectomy and underwent a below-knee amputation. An assessment of functional ambulation was performed in all 16 patients according Volpicelli scale; the lost patients were recorded last time they were visited. All ambulatory patients needed a modified heel-containment orthosis.
Conclusions: Total calcanectomy is an alternative procedure to a bellow-knee amputation in patients with chronic osteomyelitis of the calcaneus. In our hands, partial calcanectomy has worse results in eradication of infection and we have left it.
