Evaluating the late results of the Keller-Brandes operation for hallux
valgus in 100 feet on average 5.5 years after surgery, these were fun
ctionally and cosmetically satisfying to the patient in 90% of cases.
In 97% pain was relieved completely or partially. On examination, howe
ver, 23% of the feet still had a clinical hallux valgus angle of more
than 30 degrees. A dorsal extension-contracture which was found togeth
er with 50% or more of phalangeal resection was present in 6%. The pow
er of plantar flexion of the big toe decreased with the extent of rese
ction of the proximal phalanx. Resection of more than half of the prox
imal phalanx seems to be disadvantageous and should be avoided.
