Abstract
Purpose
To review two cohorts of children treated by two different protocols (repeated needle aspiration-lavage vs. arthrotomy) for surgical treatment of septic arthritis of the hip (SAH).
Methods
In order to compare between the two methods, the following parameters were checked: (a) Scar cosmesis was assessed by the Patient and Observer Scar Assessment Scale (POSAS). We considered satisfactory results (no scar discomfort) when POSAS was within 10% of the ideal score; (b) 24-h post-operative pain was evaluated by visual analog scale (VAS); (c) Complication rates of incomplete drainage (re-arthrotomy/therapy modification from aspiration-lavage to arthrotomy). The results were evaluated by the Student t-test or by the chi-square test.
Results
Seventy-nine children (aged 2–14 years) admitted during 2009–2018 and available for at least two years of follow-up were enrolled. The POSAS score (range 12–120 points) at the latest follow-up was higher in the arthrotomy group compared with the aspiration-lavage group (18.10 ± 6.22 versus 12.27 ± 1.40, p < 0.001); 77.4% of patients treated by arthrotomy had no scar discomfort. The 24-h post-intervention VAS (range 1–10) was 5.06 ± 1.29 after arthrotomy and 4.03 ± 1.13 after aspiration-lavage, p < 0.04. Complications were three times more frequent in the aspiration-lavage group (8.8% in the arthrotomy group and 26.7% in the aspiration-lavage group, p = 0.045).
Conclusions
We conclude that the lower complication rate observed in the arthrotomy group outweighs by far scar cosmesis and post-operative pain advantages in the aspiration-lavage group. Arthrotomy as a drainage method is safer than aspiration-lavage.
