The lateral column lengthening and medial column stabilization procedures

The results of medial column stabilization, lateral column lengthening, and combined medial and lateral procedures were reviewed in the treatment of a dult acquired flatfoot secondary to posterior tibialis tendon insufficiency , All bony procedures were accompanied by transfer of the flexor digitorum longus tendon to the medial cuneiform or stump of the posterior tibialis te ndon and tendoachilles lengthening or gastrocnemius recession. Medial colum n fusion was performed for naviculocuneiform and cuneiform first metatarsal sag; lateral column lengthening was performed for calcaneovalgus deformity with a flat pitch angle; and combined procedures were performed for comple x combined deformities. At 1 to 4 year followup of 65 feet, 88% of the feet that had lateral column lengthening, 80% that had medial column stabilizat ion, and 88% of the feet that had medial and lateral procedures had a decre ase in pain or were pain free. The lateral talar first metatarsal angle imp roved by 16 degrees in the patients in the lateral column lengthening group , 20 degrees in the patients in the medial column stabilization group, and 24 degrees in the patients in the combined medial and lateral procedures gr oup. The anteroposterior talonavicular coverage angle improved by 14 degree s in the patients in the lateral column lengthening group, 10 degrees in th e patients in the medial column stabilization group, and 14 degrees in the patients in the combined medial and lateral procedures group. These techniq ues effectively correct deformity without disrupting the essential joints o f the hindfoot and midfoot.
