The Physical Classification Criteria of the Ministry of Interior demands the conscripts with pes planus to take the weight-bearing true lateral radiographs of their feet. With this opportunity, we estimated the prevalence of symptoms among the conscripts with pes planus and studied the relationship between the symptoms of pes planus and the corresponding deformities on radiographs. Methods: From January 2003 to December 31 2005, all the consecutive conscripts underwent the physical checkup for their foot problems at a hospital were included. A total of 525 conscripts took the weight-bearing true lateral radiographs of their feet. The radiographs were retrieved from the picture archiving and communication systems workstation, and the talometatarsal angles, calcaneal-5th metatarsal angles, and calcaneal pitches were measured. The gold standard of being pes planus is the talometatarsal angle less than -4 degrees on the lateral radiograph. We telephone-interviewed these conscripts about their symptoms of pes planus. The subjective components of the American Orthopaedic Foot and Ankle Society midfoot and ankle-hindfoot score, body height, and bodyweight were recorded. Results: We successfully telephone interviewed 172 conscripts out of 525. Four conscripts refused to disclose their body height and bodyweight. We completed 168 questionnaires, and the response rate was 32%. After excluding 14 conscripts without pes planus, we obtained eligible 158 conscripts for further analysis. The average age, bodyweight, body height, and body mass index were 23.32±2.04 years, 72.22±9.62 kg, 173.21±5.22 cm, and 24.04±2.68 kg/m2, respectively. Eighty-two conscripts scored perfect scores of the subjective components of the American Orthopaedic Foot and Ankle Society midfoot and ankle-hindfoot scores (51.9%, 95% confidence interval 44.2% to 59.6% ). Seventy-six conscripts did not score perfect scores of the subjective components of the American Orthopaedic Foot and Ankle Society midfoot and ankle-hindfoot socres, and the prevalence of symptomatic pes planus was 48.1% (95% confidence interval 40.4% to 55.8%). When dichotomizing conscripts with or without perfect scores on the subjective components of American Orthopaedic Foot and Ankle Society midfoot scores for comparison, we found no statistically significant differences among talometatarsal angles, calcaneal-5th metatarsal angles, and calcaneal pitches. When dichotomizing conscripts with or without perfect scores on the subjective components of American Orthopaedic Foot and Ankle Society ankle-hindfoot scores for comparison, we found statistically significant differences among left calcaneal-5th metatarsal angles and left calcaneal pitches. The conscripts scored perfect scores on the subjective components of American Orthopaedic Foot and Ankle Society ankle-hindfoot scores had significantly smaller left calcaneal pitches (P = 0.008) and greater left calcaneal-5th metatarsal angles (P = 0.011). The midfoot scores were highly correlated to the ankle-hindfoot scores (rho = 0.904, P < 0.001). The body mass indexes were marginally correlated with the left calcaneal-5th metatarsal angles (rho = -0.18, P = 0.025). There were no correlations among body mass indices, subjective components of the American Orthopaedic Foot and Ankle Society midfoot scores, clacaneal-5th metatarsal angles, talometatarsal angles, and calcaneal pitches. The subjective components of the American Orthopaedic Foot and Ankle Society ankle-hindfoot scores were marginally correlated with the left calcaneal-5th metatarsal angles (rho = 0.211, P = 0.007), right talometatarsal angles (rho = 0.175, P = 0.049), and left calcaneal pitches (rho = -0.191, P = 0.016). Conclusion: Not all young adults with pes planus had significant symptoms. The symptomatic pes planus was not highly correlated with the deformities measurements on the lateral radiograph. |
