Background: Function of the first Naviculocuneiform (NC) joint has long been the subject of discussion, debate and controversy. Aim and Objectives: To investigate the effects of the tendons of peroneus longus and tibialis anterior muscles as well as the association of those interactions with the metatarsophalangeal, metatarsocuneiform and naviculocuneiform joints. Material and Methods: This research was performed on thirty-two lower limbs of adult cadavers (Anatolian population, age range 40-65 years). Study population for these lower extremities comprised 12 (37.5%) females and 20 (62.5%) males. Twenty one of the limbs were from the right extremity, 11 of them were from the left extremity. The specimens with fracture, previous surgery or arthritis were excluded. While the foot was located in anatomical position, the angles for metatarsophalangeal, metatarsocuneiform and naviculocuneiform joints in the metatarsal and sagittal planes were photographed after inserting 8-10 cm long needles. These angles were calculated by using CorelDRAW 5.00. Results: In the horizontal plane, it was found that the angle for metatarsophalangeal joint was between 4.5°-10° in females and 3.8°-9.9° in males and the angle for metatarsocuneiform joint was between 5.1°-12.6° in females and 2.7°-12.3° in males. Similarly, the angle for naviculocuneiform joint was measured between 2.1°-9.4° in females and 3°-11.4° in males. Intermetatarsal angle varied between 6°-11.2° in males and 5.5°-11° in females. Conclusion: Normal values of the angles of those joints should be kept in mind since evaluation of patient's foot deformity will be based on these results. Hence, the severity of patient's foot deformity will be assessed according to the results of those analyses in deciding the conservative or surgical treatment.
