Abstract:
PURPOSE: To determine the radiographic changes in forefoot geometry with weight-bearing. MATERIALS AND METHODS: The forefoot radiographs of 100 normal Korean adults, 50 male and 50 female volunteers, were evaluated both in nonweight-bearing and weight-bearing. The mean age was 27 years with range of 21-39 years. Those with normal feet were selected from volunteers having no history of foot problems or other musculoskeletal diseases. RESULTS: The changes of measured angle between phalanges and metatarsals with weight-bearing were as follows; Hallux valgus angle was noted to increase in 20% of the feet, decrease in 59%, and remained unchange in 21%. Intermetatarsal angle 1~2 was noted to increase in 76% of the feet, decrease in 3%, and remained unchange in 21%. Intermetatarsal angle 1~5 was noted to increase in 95% and remained unchange in 5%. Shift in medial sesamoid on weight-bearing was also not consistent. Lateral shift was noted in 27%, no shift in 66%, medial shift in 7%. CONCLUSION: The generalized concept that the angles between bones and shift of medial sesamoid in the forefoot will change consistently with weightbearing was not found.
