ABSTRACT
BACKGROUND: Pyogenic flexor tenosynovitis (PFT) is a common hand infection associated with significant morbidity. Management varies due to lack of evidence-based guidelines, typically involving surgery and antibiotics. We conducted a cohort study, comparing outcomes between different surgical methods to see if one is optimal.
METHODS: Retrospective data collection of patients who underwent surgery for PFT in a single tertiary plastic surgery unit between 21 August 2013 and 4 October 2023 was undertaken. Demographics, injury mechanism, operative details and antibiotic use were recorded. Cases involving cellulitis or osteomyelitis were excluded. Outcomes included length of stay, length of follow-up and post-operative complications. Multivariable regression analyses were performed, adjusting for age, diabetes and smoking status.
RESULTS: A total of 174 patients (mean age 47.2 years [SD 18.7]) were included. PFT most commonly resulted from animal bites (23.7% of cases). There was wide variation in antibiotic prescribing practice. Open surgery was performed in 121 cases, whilst 53 underwent minimally invasive procedures. No statistically significant differences in outcomes were observed between techniques in unadjusted or adjusted analyses. Diabetes was associated with an increased likelihood of requiring further procedures on multivariable analysis.
CONCLUSION: There is no evidence of differing outcomes for open or minimally invasive techniques. Diabetes may be associated with a requirement for further procedures. However, these results should be interpreted in the context of the retrospective design, missing data and potential for confounding by indication. Standardised, evidence-based management guidelines are required, with prospective multi-centre studies needed to better define optimal treatment strategies.
