ABSTRACT
To find normal radiological values for measuring the adult Thai foot. Material & Methods : One hundred and six films of both feet while standing in AP and lateral views including 32 men and 74 women age from 19 to 77 years old were studied. There were 5 groups of studied group 1, 58 people with normal feet, group 2, 11 people with a diagnosis of tendoarchillis tendinitis, group 3, 22 people with a diagnosis of plantar fasciitis, group 4, 10 people with a diagnosis of an accessory articular bone group 5, 5 people with a diagnosis of hallux valgus. The radiological measurements in AP view were the talocalcaneal angle (TCAP), the talo-first metatarsal angle (TF) the calcaneofifth metatarsal angle (CF), the first metatarsophalangeal angle (M1P1) the first metatarso-second metatarsal angel (M1M2), the first metatarsofifth metatarsal angle (M1M5), the forth metatarso fifth metatarsal angle (M4M5) and the first proximal phalanx - distal phalanx angle (P1D1). In a lateral view the angles measured were the talocalcaneal (TC lat), tibiotatar (TIT), the tibiocalcaneal (TIC), the calcaneal pitch (CP), and the Bohler angle (BA). Results : There were no statistical significant difference of the angles between 5 group of feet except M1P1. The normal values in mean angle in AP view for left and right feet were 17.89o, 17.58o, for TCAP, -0.79o, 0.15o, for TF, 6.86o, 7.45o for CF 11.69o, 10.68o for M1P1, 9.33o, 9.20o for M1M2, 26.41o, 27.00o for M1M5, 8.64o, 8.76o for M4M5, 11.57o, 10.86o for P1D1. The mean angle in lateral view for left and right feet were 38.33o, 38.72o for TClat, 104.4o, 106o for TIT, 63.54o, 67.48o for TIC, 17.52o, 17.45o for CP, 30.53o, 34.46o for BA angle. Conclusion: The normal values in radiological measurement of adult Thai foot can be used to evaluate the result of the treatment in foot deformities. The problem in common foot problems such as plantar fasciitis etc. were in the soft tissue not in the structure of the bone.
