Cetylated Fatty Acids (CFAs) are a group of naturally occurring fatty acids that have been studied for their anti-inflammatory and lubricating properties, particularly in joint-related conditions. Several small-scale, randomized controlled trials and pilot studies have examined the use of topical CFAs in the management of musculoskeletal disorders, particularly osteoarthritis and, to a lesser extent, bursitis. The proposed mechanism involves enhancing membrane fluidity, reducing inflammation, and improving joint mobility.

In the context of bursitis, evidence is limited but present. A few clinical studies and case reports suggest that topical application of CFA creams or lotions may help reduce pain and improve function in patients with various soft tissue inflammation, including bursitis, though most data are extrapolated from studies on osteoarthritis or general joint pain. For example, a double-blind, placebo-controlled trial by Hesslink et al. (2002) showed benefit in knee osteoarthritis, and some observational reports mention improvement in bursitis symptoms. However, large, high-quality trials specifically targeting bursitis are lacking.

In summary, the use of cetylated fatty acids for bursitis is scientifically explored but not strongly validated. The overall evidence quality is low to moderate (rated 2/5), with more robust studies needed to confirm efficacy for bursitis specifically.
