Current dogma is that a programme of anatomic repositioning with rigid internal fixation of fractures will lead to successful healing. Failures are attributed to failures in technique, not in instruments, implants, or concepts. Current basic science research shows that in the osteoporotic skeleton, bone trabeculae, once lost, are not replaced. This is true in fractures. In a series of cases, the author will show that lost bone is indeed not replaced, and the unsuccessful clinical outcome is caused by adherence to concepts that do not solve the problem of fracture repair in the elderly. Five specific case examples will be shown to demonstrate this problem. Despite an abundance of bone graft substitutes, bone morphogenic protein preparations, and cancellous bone autografting, the problem of dependable fracture repair in the elderly skeleton still needs to be solved.
We reviewed 1085 consecutive compound limb fractures treated in 914 patients at the University of Louisville over a nine-year period. Of these fractures, 240 (group 1) received only systemic antibiotic prophylaxis and 845 (group 2) were managed by the supplementary local use of aminoglycoside-polymethylmethacrylate (PMMA) beads. There were no significant differences in age, gender, fracture type, fracture location or follow-up between the two groups. All had copious wound irrigation, meticulous debridement and skeletal stabilisation, but wound management and the use of local antibiotic depended on the surgeon's individual preference and there was no randomisation. In group 1 there was an overall infection rate of 12% as against 3.7% in group 2 (p <
0.001). Both acute infection and local osteomyelitis showed a decreased incidence in group 2, but this was statistically significant only in Gustilo type-IIIB and type-IIIC fractures for acute infection, and only in type-II and type-IIIB fractures for chronic osteomyelitis. Our review suggests that the adjuvant use of local antibiotic-laden PMMA beads may reduce the incidence of infection in severe compound fractures.
