Abstract
Aim
Chronic osteomyelitis of the calcaneus is a frequent problem in a population of diabetic patients, patients with neurologic disorders or bedridden patients with ulcers. Partial calcanectomy is an alternative option which avoid major amputation. The aim of this retrospective study was to determine the effectiveness of partial calcanectomy for treating chronic osteomyelitis of the calcaneux.
Method
We conducted a retrospective review of patients who underwent in our department a partial calcanectomy between 2006 and 2015. All patients with a complete set of radiographs and adequate follow-up (minimum 2 years) were included. We reviewed these cases to determine healing rate, microbiological analysis, risk factors of failure (comorbidities), limb salvage rate and survival rate. We analyzed specifically the footwear and the functional subjective evaluation according to the LEFS score (Lower Extremity Functional Scale).
Results
Twenty-four patients were included (24 foot). There were 17 men and the mean age was 65.2 years. The control of the infection and the healing was obtained in 15 cases. An additional surgery was required in 46% of the cases. A transtibial amputation has been realized in 9 cases because of uncontrolled infection. The existence of a preoperative vascular disease increased 5,9 times the risk of amputation after a partial calcanectomy (p=0,033). The type of germ was not related to the risk of recurrence. Soles were necessary for 60% of the patients with a successful partial calcanectomy (n=15). The average LEFS score was 51/80.
Conclusion
The treatment of the chronic osteomyelitis of the calcaneus was a therapeutic challenge for these patients. The partial calcanectomy is a useful procedure for limb salvage, but the selection of patients must be rigorous. In our study, arteriopathic patients had a high risk of amputation after partial calcanectomy. When the healing is acquired, the patients were satisfied and presented a good function.
