A novel technique for fabricating antibiotic-coated intramedullary nails using an antibiotic-loaded calcium sulphate hydroxyapatite bio-composite, Cerament-V.

Abstract

Deformity correction in the setting of osteomyelitis is a challenge for any orthopaedic surgeon. Principles of management are well described and include staged debridement, stable fixation and a combination of local and systemic antibiotic therapy. An antibiotic-coated nail (ACN) can prove a useful tool—stabilizing bone, whilst allowing for local antibiotic elution. Typically, the surgeon will prepare these implants in the operating room using materials that are routinely at hand. Most frequently, this will involve the use of antibiotic-loaded poly-methyl methacrylate (PMMA). This method of ACN fabrication has several disadvantages. PMMA is non-degradable and can be difficult to remove surgically. There are limitations with regard to antibiotic suitability, antibiotic release as well as toxicity effects. In this case report, we present a novel technique for the preparation of ACNs for use in hindfoot surgery, using a calcium sulphate/hydroxyapatite-based bio-composite—Cerament-V.
