This study evaluates the results of external and internal fixation techniques for arthrodesis of the ankle.
Perioperative and subjective, clinical, and radiological long-term results (average follow-up: 9 years) in 55 patients following arthrodesis of the ankle due to posttraumatic arthritis were compared in two groups with different fixation techniques--compression arthrodesis with external fixator (AO) or internal screw fixation.
Patients with external fixation revealed a significantly higher deep infection rate, which was treated conservatively, while the rates of nounion, revision surgery due to infection, and total revision surgery did not show any difference in the two groups.
Both surgical techniques applied mostly guarantee a safe and stabile fixation in arthrodesis of the ankle and provide convincing long-term results without showing a difference in comparing the outcome.
本研究评估踝关节融合术的外固定和内固定技术的结果。
将55例因创伤后关节炎行踝关节融合术的患者分为两组，分别采用不同的固定技术——外固定器加压融合术（AO）或内螺钉固定术，比较两组的围手术期及主观、临床和放射学长期结果（平均随访9年）。
外固定患者的深部感染率显著更高，采用保守治疗，而两组的不愈合率、因感染进行翻修手术的比率以及总翻修手术率均无差异。
所应用的两种手术技术大多能确保踝关节融合术的安全稳定固定，并提供令人信服的长期结果，比较结果无差异。
