ABSTRACT
BACKGROUND:
The AFCP (French Association of Foot Surgery) classification was recently introduced as a reliable and quick visual method for the assessment of sagittal plane deformities of the second toe. The aim of this study was four-fold (1) to describe a new toe-ground area score (TAS) as an additional dynamic tool of such classification, (2) to verify whether all second toe deformities could be classified, (3) to assess the TAS intra- and inter-observer reliability and (4) to evaluate the TAS learning curve.METHODS:
In this retrospective study 52 s toes were evaluated using a podoscope. Ten foot and ankle surgeons assessed independently standardised videos of each case acquired in a blinded fashion. Assessment was repeated three times, 15 days apart. Intra- (Intraclass Correlation Coefficient or ICC) and inter-observer reliability (Fleiss' Kappa coefficient) were calculated. Mean time to assess a deformity was also recorded.RESULTS:
All the 522 observations (52 feet assessed by 10 surgeons) were successfully rated using the TAS. Intra- and inter-observer reliability were substantial for the first round (ICC 0.79; Kappa 0.76) and excellent for the second (ICC 0.88; Kappa 0.8) and third round (ICC 0.84; Kappa 0.81). Mean assessment time ± standard deviation was 22 ± 11 s per case for the last two rounds.CONCLUSIONS:
The TAS has been proven reliable and quick in the assessment of second toe deformities. When combined with a static segmentary classification of the toe (such as the AFCP classification) it might provide further dynamic informations about the ability of the toe to engage the ground.
