ABSTRACT
Introduction: Dead space management following intramedullary debridement and reaming
can be challenging and several alternatives have been described. The main objective of this
study was to investigate the clinical outcome and resolution rate in patients treated for fracture
related Cierny and Mader anatomical type 1 intramedullary chronic osteomyelitis by means of
continuous irrigation (modified Lautenbach system) as dead space management following
intramedullary reaming.
Material and Method: A consecutive series of thirty patients with Cierny and Mader type 1
chronic osteomyelitis, treated between May 2016 and September 2019, were evaluated
retrospectively. Patient history and clinical information, including imaging and laboratory
results, were reviewed. Treatment procedures and antibiotic profiles were also recorded.
Results: The initial cohort included 30 cases with 18 tibias, 11 femurs and one humerus.
Seven patients were excluded; three patients did not return for follow up and four patients had
less than six months follow up. Of the remaining 23 patients, 91% (21/23) achieved resolution
of infection over a median follow up period of 16 months (Interquartile range, IQR 7-21
months). Infecting organisms where isolated in 65% (15/23). The median duration of hospital
stay was 6 days (IQR 4-7 days). Post-operative complications were noted in two cases and
involved a tibial and femoral refracture, respectively. Both patients however achieved union
without recurrence of infection following surgical intervention.
Conclusion: Continuous irrigation is a cost-effective single-stage surgical option for dead
space management during the treatment of intramedullary chronic osteomyelitis. It provides
the advantage of instilling high dose intramedullary antibiotics and negates the need for a
second surgical procedure while achieving similar outcomes than other dead space
management techniques.
