CUBOID PLANTAR AND DORSAL SUBLUXATIONS - ASSESSMENT AND TREATMENT

Plantar flexion and inversion stresses at the ankle may cause the tars al cuboid to sublux in a plantar or dorsal direction resulting in pain and impaired joint function. Subluxation of the tarsal cuboid alters the passive physiological motion and accessory glides of the cuboid jo ints in characteristic patterns of motion restriction. Identification of the pattern of motion restriction is necessary for appropriate diag nosis and treatment. This paper presents the case reports of two patie nts with lateral foot pain. A subluxed cuboid bone was believed to be the cause of the patient's pain. Assessment and treatment are describe d and possible pathomechanics for cuboid subluxation are presented. Pa ssive physiological motion of the cuboid and accessory joint glides sh ould be assessed in patients complaining of lateral foot pain or with inversion ankle injuries. Pain and joint impairment can be alleviated with proper assessment and treatment.
