Intramedullary infection in long bones represents
a complex clinical challenge, with an increasing incidence due to the
increasing use of intramedullary fixation. We report a prospective
case series using an intramedullary reaming device, the Reamer–Irrigator–Aspirator
(RIA) system, in association with antibiotic cement rods for the
treatment of lower limb long bone infections. A total of 24 such
patients, 16 men and eight women, with a mean age of 44.5 years
(17 to 75), 14 with femoral and 10 with tibial infection, were treated
in a staged manner over a period of 2.5 years in a single referral
centre. Of these, 21 patients had had previous surgery, usually
for fixation of a fracture (seven had sustained an open fracture
originally and one had undergone fasciotomies). According to the
Cierny–Mader classification system, 18 patients were classified
as type 1A, four as 3A (discharging sinus tract), one as type 4A
and one as type 1B. Cite this article:
Fragility fractures of the ankle occur mainly in elderly osteoporotic women. They are inherently unstable and difficult to manage. There is a high incidence of complications with both non-operative and operative treatment. We treated 12 such fractures by closed reduction and stabilisation using a retrograde calcaneotalotibial expandable nail. The mean age of patients was 84 years (75 to 95). All were women and were able to walk fully weight-bearing after surgery. There were no wound complications. One patient died from a myocardial infarction 24 days after surgery. The 11 other patients were followed up for a mean of 67 weeks (39 to 104). All the fractures maintained satisfactory alignment and healed without delay. Six patients refused removal of the nail after union of the fracture. The functional rating using the scale of Olerud and Molander gave a mean score at follow-up of 61, compared with a pre-injury value of 70.
