Surgical treatment of acquired flatfoot deformity: what is the state of practice among academic foot and ankle surgeons in 2002?
OBJECTIVE
This study was performed to review the present approach to the surgical treatment of acquired flatfoot deformity among a cross section of academic foot and ankle surgeons in the United States.


METHODS
A typical case of stage II posterior tibial tendon dysfunction was developed. The hypothetical patient was a healthy 62-year-old male with a symptomatic acquired flatfoot deformity with posterior tibial tendon dysfunction. Nonoperative management had failed. A series of academic foot ankle surgeons were surveyed to identify their proposed operative treatment. Each surgeon surveyed was affiliated with an orthopaedic residency program and was directly responsible for teaching orthopaedic residents. Each surgeon had foot and ankle patients as the major component of their practice. The overall response rate was 81% (104/128).


RESULTS
Ninety-seven percent (101/104) of respondents reported that they would employ some type of bony procedure in their surgical treatment. Eighty-eight percent (89/104) described techniques that would preserve the subtalar and talonavicular joints. These included a medializing calcaneal osteotomy in 73% (76/104), a lateral column lengthening in 41% (43/104), and a medial column stabilization (first tarsometatarsal and/or navicular cuneiform arthrodesis) in 15% (16/104). Twelve percent (12/104) reported that they would perform an arthrodesis of one or more of the hindfoot joints. Ninety-eight percent (102/104) of respondents reported that they would employ some type of soft-tissue procedure. Ninety-four percent (98/104) would augment the posterior tibial tendon, 53% (55/104) would formally repair the spring ligament, and 70% (73/104) would address a presumed equinus contracture.


CONCLUSIONS
There is a wide variation in the approach to surgical treatment of stage II acquired adult flatfoot deformity among academic foot and ankle surgeons. Most surgeons employed a combination of bony and soft-tissue procedures that preserved the subtalar and talonavicular joints.
