Kirschner wires (K-wires) are used in fracture fixations but are often associated with pin tract infections. This prospective study compared the infection rate between buried and exposed K-wires in closed injuries of the wrist and hands in individuals with no comorbidities.
Fifteen patients were recruited with a total of 41 K-wires (21 buried K-wires; 20 exposed K-wires). Clinical and radiographic evidence of infection was assessed at three months based on the Modified Oppenheim classification.
Two out of 21 wires in the buried group developed grade 4 infection, while 20 wires in the exposed group did not have any significant infection. No significant difference in infection rate based on K-wire size or number in both groups.
There is no significant difference in infection rate between buried and exposed K-wires in healthy individuals with closed injuries of the wrist and hand.
克氏针用于骨折固定，但常伴有针道感染。本前瞻性研究比较了无合并症个体手腕和手部闭合性损伤中，埋入式克氏针与外露式克氏针的感染率。
招募了15名患者，共使用41根克氏针（21根埋入式克氏针；20根外露式克氏针）。基于改良奥本海姆分类法，在三个月时评估感染的临床和影像学证据。
埋入组21根克氏针中有2根发生4级感染，而外露组20根克氏针未发生任何明显感染。两组中基于克氏针尺寸或数量的感染率无显著差异。
在手腕和手部闭合性损伤的健康个体中，埋入式克氏针与外露式克氏针的感染率无显著差异。
