Abstract
BackgroundFifth metatarsal basis fractures are common injuries. Zone 1 fractures are also known as pseudo-jones fractures. This study aimed to elucidate the impact of foot radiologic morphology on pseudo-Jones fractures. MethodsPatients with pseudo-Jones fractures formed the case group and individuals with ankle sprains but no fractures formed control group. Weight-bearing anteroposterior and lateral radiographs were evaluated for pre-determined measurements: metatarsus adductus angle (MAA), intermetatarsal angles (1−2, 4−5), calcaneal inclination (CI) angle, and fifth metatarsal base angle. All measurements were performed by a single investigator using digital PACS tools. Statistical analysis compared these radiographic parameters between the groups. ResultsThe fracture group demonstrated a significantly lower 4–5 intermetatarsal and calcaneal inclination angles than the control group (p < 0.05). Notably, no statistically significant difference was found in the metatarsus adductus angle. ConclusionThis study demonstrates a potential association between foot radiographic morphology and pseudo-Jones fractures. Patients with a lower 4–5 IMA and calcaneal inclination angle may be at a higher risk for developing pseudo-Jones fractures. However, these requires future prospective studies.
