Breakage of K-wires and stainless steel wires which are used for fracture fixation is not uncommon, but migration is rare. We report a case of migration of broken K-wire used for patella tension band wiring to the popliteal fossa. The broken hardware was removed surgically. We would like to suggest that K-wire and wire fixation used for treatment of patellar fractures can migrate into the posterior compartment of the knee and cause clinical symptoms. Close clinical and radiological follow-up after internal fixation to identify the presence of hardware breakage or movement and removal of wires once fracture has united can avert such complications.
用于骨折固定的克氏针和不锈钢丝断裂并不罕见，但移位很少见。我们报告一例用于髌骨张力带钢丝固定的断裂克氏针移位至腘窝的病例。手术取出了断裂的内固定物。我们建议，用于治疗髌骨骨折的克氏针和钢丝固定可能会移入膝关节后室并引起临床症状。内固定后密切的临床和影像学随访以确定是否存在内固定物断裂或移位，以及骨折愈合后取出钢丝可避免此类并发症。
