Final answer:
The capsular pattern of the midtarsal joint is a characteristic restriction with more limitation in plantarflexion than dorsiflexion, along with limited inversion and eversion due to inflammation of the joint capsule.
Step-by-step explanation:
The capsular pattern of the midtarsal joint, also known as Chopart's joint, refers to a characteristic pattern of restriction occurring when the synovial capsule of a joint is inflamed. Since the midtarsal joint is a complex joint that assists in various movements of the foot, a capsular pattern in this joint may present as more limitation in plantarflexion than in dorsiflexion, along with limited inversion and eversion. These limitations are a result of the inflammatory response and subsequent restriction in the joint capsule affecting the range of motion. Among various joints in the body, each has a unique capsular pattern, which helps clinicians in diagnosing joint pathologies.
