Metatarsophalangeal Joint Instability of the Lesser Toes and Plantar Plate Deficiency

Journal of th American Academy of Orthopaedic Surgeons: April 2014, Vol 22, No 4

Abstract: Our understanding of lesser toe metatarsophalangeal joint instability has increased substantially over the past few decades. Some recent articles on the subject have provided detailed anatomic descriptions that help to characterize the primary stabilizing structures of the joint. Some surgeons now advocate the incorporation of a primary repair of the plantar plate into the surgical plan for correction of metatarsophalangeal joint deviation in the sagittal and transverse planes. New surgical techniques have been developed to expose, inspect, and reliably repair the plantar plate, if necessary. Dorsal and plantar approaches have both been used successfully to repair the plantar plate. Tears of the plantar plate can be repaired primarily or advanced on the base of the proximal phalanx through bone tunnels. Outcomes of these procedures are promising, with improvements in pain and function reported along with sustained deformity correction.
