We present a case of a 49-year-old patient who initially presented in May 2020 with an open pilon fracture. Managed with initial debridement, fixation and flap - who subsequently underwent circular frame application for failure of fixation, requiring a transport to fusion frame who developed beta-haemolytic streptococcus A within the site of the proximal corticotomy. A systematic review of the literature was conducted searching EMBASE, MEDLINE and Cochrane library for all articles discussing infected bone regenerate- a paucity of information was found. Abstracts were independently reviewed by 2 authors (LH and LT). In total, there were 16 papers, and then subsequently analysed we identified two case reports regarding infected regenerate.Introduction
Materials & Methods
To evaluate clinical outcomes for patients with osteomyelitis at a major trauma centre limb reconstruction unit. We prospectively evaluated 137 patients on the limb reconstruction database with long bone osteomyelitis. Data on initial diagnosis, management (bone resection, use of external fixation, dead space and soft tissue management), microbiology and 2-year outcomes were collated. 11 patients' data was incomplete and 9 underwent primary amputations; these were excluded from microbiology data analysis. The patient data was categorised into microbiological culture negative or culture positive groups. Inter-group comparisons were made to evaluate two-year outcomes and percentage failure rate.Aim
Method
Current standard of care in the management of bone and joint infection commonly includes a 4–6 week course of intravenous (IV) antibiotics but there is little evidence to suggest that oral antibiotic therapy results in worse outcomes. The primary objective was to determine whether oral antibiotics are non-inferior to IV antibiotics in this setting. This was a parallel group, randomised (1:1), open label, non-inferiority trial across twenty-six NHS hospitals in the United Kingdom. Eligible patients were adults with a clinical diagnosis of bone, joint or orthopaedic metalware-associated infection who would ordinarily receive at least six weeks of antibiotics and who had received ≤7 days of IV therapy from the date of definitive surgery (or the start of planned curative treatment in patients managed non-operatively). Participants were randomised to receive either oral or IV antibiotics for the first 6 weeks of therapy. Follow-on oral therapy was permitted in either arm. The primary outcome was the proportion of participants experiencing definitive treatment failure within one year of randomisation. The non-inferiority margin was set at 7.5%.Aim
Method
Bone infection can recur months or years after initially successful treatment. It is difficult to review patients for many years to determine the true incidence of recurrence. This study determined the minimum follow-up period which gives a good indication of the recurrence rate after surgery for chronic osteomyelitis and infected non-union. We studied five cohorts of patients who had surgery for long bone infection, over a 10 year period. We investigated the efficacy of various antibiotic carriers (PMMA and Collagen; n=185, Calcium Sulphate; n=195, Calcium Sulphate/Hydroxyapatite; n=233) and management of infected non-unions (n=146). Patients were reviewed and Kaplan-Meier Survivorship curves were constructed to show the incidence and timing of recurrence. The microbiology of the initial infection and the recurrent culture was also compared.Aim
Method
Infection following traumatic injury of the tibia is challenging, with surgical debridement and prolonged systemic antibiotic therapy well established. Local delivery via cement beads has shown improved outcome, but these often require further surgery to remove. Osteoset-T is a bone-graft substitute composed of calcium sulphate and 4%-Tobramycin, available in pellets that are packed easily into bone defects. Concerns remain regarding the sterile effluent produced as it resorbs, along with the risk of acute kidney injury following systemic absorption. We present outcomes of 22 patients treated with Osteoset-T.Introduction
Purpose
Tibial non-union causes significant morbidity and functional impairment. Circular frames are valuable tools in the treatment of non-union, however prolonged treatment often causes patients increased morbidity due to pin site problems together with personal and emotional strains. The purpose of this study was to assess patient centred outcomes following treatment of tibial non-union in circular frame. We identified 21 patients who had undergone treatment of tibial non-union using a circular frame. Patients were sent questionnaires utilising the Enneking scoring system and EQ-5D general health questionnaire. Fourteen patients responded. There were 3 females, mean age was 48.2 years. The average number of previous operations was 1.2. All patients went on to achieve union with a mean 10.1 months (6–20) in frame. The mean Enneking score was 58.0% (34.3–77.1). Two patients were enthusiastic about their treatment, two liked it, three were satisfied, four accepted and would do it again while three accepted it but would not do it again. The Euroqol questionnaire results showed that 8 patients had some difficulty with mobility, 10 had some difficulty with usual activities and 12 moderate pain. There was no significant difference in the EQ VAS score of overall health state for treated patients compared with predicted scores for an age and sex matched UK population (77.7 vs 83.1, p=0.07). Our study shows that many patients undergoing limb salvage with circular frames for tibial non-union continue to have clinically significant symptoms, however the majority would undergo similar treatment again and we found no difference in overall health state compared with age and sex matched predicted scores. Circular frames are undoubtedly a valuable tool in the management of non-union however patients should be given realistic counselling regarding the treatment and expected outcome.
To identify the most common infecting organisms associated with deep infection and infected non-union of the tibia, as well as the rate of ‘culture-negative’ infections, at a tertiary referral trauma centre dealing with military and civilian trauma. Between 2008 and 2010 all patients with a confirmed clinical diagnosis of implant-related infection or infected non-union of the tibia were identified retrospectively from a database and their records analysed. After a period of at least 10–14 days without antibiotics, all patients underwent surgical debridement in which ‘clean’ samples were went for microbiological analysis. Skeletal stablity was achieved with a circular frame and intravenous antibiotics were started pending culture and sensitivity results.Aims
