Summary

A meta-analysis was performed to compare rate of SSI after application of chlorhexidine vs. iodine in total joint arthroplasty. Chlorhexidine had significantly lower odds of SSI.

Introduction

Surgical site infections (SSI) are a significant source of morbidity and mortality. The optimal preoperative skin preparation in lower extremity total joint arthroplasty (TJA) remains debatable between chlorhexidine and iodine-containing solutions. This meta-analysis sought compare SSI rates between chlorhexidine cloth application the night before surgery plus povidone-iodine-alcohol (povidone-iodine) solution at surgery or only povidone-iodine at surgery.

Introduction and Aims: To assess the efficacy of fibular osteotomy on the rate of arthrodesis at the tibiofibular syndesmosis in patients with Total Ankle Replacement (TAR).

Method: A prospective trial of fibular osteotomy was performed in 16 consecutive TAR (13F/3M), mean age 67 (41–82). All operations were performed by the same surgeon, as described by the inventor of the procedure, Dr. Frank Alvine, MD. After completion of the syndesmotic fusion, the fibula was exposed proximal to the proximal syndesmotic screw. An oblique osteotomy of the fibula was performed. Importantly, the angle of the cut was made such that the proximal fibula was trapped by the distal cut surface. The osteotomy was directed from medial distal to lateral proximal. All cases were followed until radiographic and clinical signs of healing were seen.

Results: Union occurred in all cases, with a mean time to fusion of seven weeks, with six patients achieving union within five weeks. No patient developed pain at the osteotomy site. All osteotomies showed signs of radiographic healing and none of these were symptomatic. There were no neuromas related to this procedure, and no patient experienced sensory changes along the nerve distribution. One patient developed symptomatic prominence of the screw on the medial malleolus and was asypmtomatic after implant removal.

Conclusion: The addition of a fibular osteotomy resulted in a 100% rate of syndesmosis fusion. We postulate that the osteotomy is successful because it removes the micromotion at the syndesmosis, which occurs with loading of the intact fibula. As the fibula only functions as a lateral strut in patients with an Agility total ankle, we felt that the osteotomy would cause minimal if any concerns. Our findings corroborate our hypothesis in that all the fusions were successful and none of the patients experienced secondary problems related to the osteotomy. We would recommend this technique as an adjunct to standard ankle replacement using the Agility system.
