"This facilitates the eradication of infection and also prepares the wound bed for subsequent bone grafting," they said in a review of their results of using their treatment protocol. "Rigid internal fixation of the bone graft to the recipient area allows for early range of motion, which maximizes functional outcome. Leaving the wound open allows for drainage and prevents the accumulation of fluid, which may inhibit union, and the eradication of infection.
"Although we were not always able to achieve full range of motion, we had achieved union in all our patients with concurrent resolution of infection. We believe that our protocol offers a viable option in the management of infected nonunion of the forearm with excellent chance for union and good functional results.
Their exhibit presents a retrospective review of 14 patients who presented to them with infected nonunion of the forearm. Nine were male and five were female. Both bones were affected in 12 patients and the ulna only in two patients. The mean age of the patients was 45.7 years. Ten fractures were open.
All fractures were initially treated with open reduction and internal fixation. Nine presented with open drainage. Only three had an elevated ESR (>20) and only four with increased WBC count (>9,000). The patients had an average of 5.4 (2-16) procedures prior to presenting to the researchers' institution. Their treatment protocol consisted of:
All patients ultimately achieved infection-free union of the forearm. The average time period until union was three months (excluding one patient). Thirteen patients achieved infection-free union after their initial treatment. A functional range of motion was obtained in 11 patients (defined as supination 50 degrees and pronation 50 degrees with elbow ROM at least 30-130).
The three patients who fell below our cutoff for functional range of motion had the most previous procedures (average 12 per patient). Complications included one recurrence of infection, one delayed union, one ulnar impingement and three with limited supination/pronation.
"We believe that our protocol offers a viable option in the management of infected nonunion of the forearm with excellent chance for union and good functional results, the coauthors say.
