Abstract
Category:OtherIntroduction/Purpose:The cavovarus foot is a true challenge for both the patient and the surgeon. This complex deformity can be a result of many different causal factors including genetics, Charcot-Marie-Tooth disease, diabetes and spina bifida. It may also be caused or worsened by trauma or surgical procedures. The cavovarus foot is difficult to manage conservatively as it tends to be rigid, is not a good shock absorber and causes the joints of the foot to process abnormal stresses. The mechanical construct of a cavus foot makes it susceptible to a multitude of complications and injuries like inversion ankle sprains and metatarsal stress fractures.Methods:While foot orthoses would likely be the most commonly considered conservative treatment option for the symptomatic cavus foot, other modalities like shoe modification, bespoke and/or therapeutic footwear and bracing have also proven effective. Oftentimes, a combination of the aforementioned options is employed. Given the individual complexities of each cavus foot, the conservative treatment plan is typically custom tailored to fit a particular patient's foot structure, biomechanical and corrective needs, and occupational or recreational demands. A so-called 'cookie cutter' approach is not appropriate for management of the cavovarus foot.Results:A review of published research demonstrates that foot orthoses - and other conservative modalities - are effective in the treatment of the cavus foot. These devices work by correcting the varus foot alignment (when applicable), offloading painful areas such as ball of the foot or the base of the fifth metatarsal, providing shock absorption and replacing lost motion. These applications work together to provide a more normal, safer and energy-efficient gait.Conclusion:Conservative management, specifically pedorthics, is not only a viable treatment option for the cavovarus foot but should be considered integral to the overall management of the cavus foot patient. Pedorthic modalities are successfully used post-operatively or in lieu of surgical intervention. Modern pedorthics (technological advances in shoe and orthotic design, construction and materials) allows for cosmetically pleasing, affordable and comfortable management allowing patients to return to a healthy and active lifestyle in many cases.
