Hallux rigidus (HR) is a progressive and degenerative condition of the first metatarsophalangeal (MTP) joint that is categorized into five stages depending on pain and the range of motion of the joint. It is one of the most prevalent great toe conditions experienced by patients over the age of fifty. Effective treatment can manage discomfort and potentially slow the joint degeneration; however, there is no treatment method on the market that can selectively limit the degrees of dorsiflexion and subsequent pain of the different HR stages. This project highlights the current treatments for HR and their shortcomings while also proposing a better solution. An in-shoe orthotic composed of a base and an easily detachable variable stiffness spring insert is suggested to allow rapid targeting of the specific HR stage. By varying the thickness of the spring steel insert, the orthotic allows the clinician to choose a specific maximum degree of dorsiflexion for the patient's joint based on their diagnosed stage of HR, weight, and activity level. Prototypes were created and tested to establish a user-friendly, clinical chart that allows clinicians to input their patient's weight and stage of HR to determine the appropriate insert for treatment. Finite element analysis and physical testing were done, and the data was used to create the first iteration of the clinical chart. Further work is needed to improve the precision and accuracy of the chart, but the concept of creating variable resistance to movement using an interchangeable, clinician-adjustable orthotic has been proven and is a very promising concept for the future of HR treatment.
