Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Vitamin D is important for bone health and recent research has emphasized the importance of adequate vitamin D levels for bone healing, wound healing, and possibly preventing infections post-operatively. This study will assess the effect of vitamin D supplementation on patient outcomes following ankle arthrodesis or first metatarsophalangeal joint arthrodesis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The current status of knowledge includes preliminary research correlating hypovitaminosis, or low vitamin D status, to worse outcomes. In orthopaedic patients, vitamin D deficiency is prevalent among those scheduled to undergo surgery.

Vitamin D is important for calcium homeostasis and bone health, as well as for activation and differentiation of macrophages, dendritic cells, and lymphocytes. A recent retrospective review of outcomes in revision total joint arthroplasty patients showed that patients with low vitamin D had higher rates of postoperative complications and periprosthetic infections. Additionally, another retrospective study correlated low vitamin D levels with lower patient reported outcomes (PROs) after total hip arthroplasty. Current retrospective studies suggest that having low vitamin D levels may lead to impaired fracture healing, increased wound complication rates, and a higher risk of infections.

Given this background information, this study will investigate a series of patients undergoing ankle arthrodesis and first metatarsophalangeal joint (MTP) arthrodesis. Our study will serve to enhance the current knowledge as a level 1 randomized control study on the effect of Vitamin D supplementation on the complication rate following these two arthrodesis procedures. Our endpoints for complications will be defined as infection, wound healing complications, need for readmission, need for re-operation and nonunion as evidenced clinically and radiographically.
