Purpose.
To investigate the effect of cuboid osteotomy lateral column lengthening (LCL) for the correction of stage II B adult-acquired flatfoot deformity in cadaver.
Methods.
Six cadaver specimens were loaded to 350 N.
Flatfoot models were established and each was evaluated radiographically and pedobarographically in the following conditions: (1) intact foot, (2) flatfoot, and (3) cuboid osteotomy LCL (2, 3, 4, and 5 mm).
Results.
Compared with the flatfoot model, the LCLs showed significant correction of talonavicular coverage on anteroposterior radiographs and talus-first metatarsal angle on both anteroposterior and lateral radiographs (p<.05).
Compared with the intact foot, the above angles of the LCLs showed no significant difference except the 2 mm LCL.
In terms of forefoot pressure, medial pressure of the 2 mm LCL (p=.044) and lateral pressure of the 3, 4, and 5 mm LCLs showed statistical differences (p<.05), but lateral pressure of the 3 mm LCL was not more than the intact foot as compared to the 4 and 5 mm LCLs, which was less than medial pressure.
Conclusion.
Cuboid osteotomy LCL procedure avoids damage to subtalar joint and has a good effect on correction of stage II B adult-acquired flatfoot deformity with a 3 mm lengthening in cadavers.
