We evaluated the incidence of pin-tract infection (PTI) during limb lengthening using external fixation in 88 patients and the effects of infection on final outcomes and incidence of additional procedures. The PTI rate was 96.6%. The rate of half-pin site infection was significantly (P<.05) higher in half-pin fixators (100%) than in hybrid fixators (78%). There was a significantly (P<.05) higher incidence of half-pin site infection (78%) than fine-wire site infection (33%). The rate of additional surgeries for treating PTI was higher for half-pin sites than for fine-wire sites. Three (3.4%) of the 88 cases led to chronic osteomyelitis. Careful insertion and a simple, well-defined, excellent pin-care protocol can minimize PTI.
我们评估了88例使用外固定进行肢体延长患者的针道感染（PTI）发生率，以及感染对最终结局和额外手术发生率的影响。PTI发生率为96.6%。半针固定器的半针部位感染率（100%）显著高于混合固定器（78%）（P<0.05）。半针部位感染的发生率（78%）显著高于细针部位感染（33%）（P<0.05）。治疗PTI的额外手术率，半针部位高于细针部位。88例中有3例（3.4%）导致慢性骨髓炎。仔细插入并采用简单、明确、良好的针道护理方案可将PTI降至最低。
