ABSTRACT

Foot and ankle pain are common presenting symptoms that can have a significant impact on the quality and activity of daily living. The foot is imaged in an oblique axial plane through the long axis of the metatarsal bone. TPT maintains the longitudinal arch of the foot in conjunction with the spring ligamentous complex. Patients present with persistent lateral foot pain after a history of trauma with ankle inversion. Predisposing factors include hypertrophy of the abductor hallucis muscle, which is often seen in long distance runners, hindfoot valgus deformity, calcaneal spur, plantar fasciitis and seronegative spondyloarthropathies. Patients present with sensory changes in the lateral one-third of the plantar surface of the foot as well as motor weakness of the abductor digiti minimi. Early identification and treatment of Charcot neuropathic osteoarthropathy is key as delayed diagnosis can lead to foot and ankle deformity, foot ulceration, osteomyelitis and amputation.
