简要总结
This study will evaluate the usefulness of ultrasonography in detecting dorsal osteophytes associated with claw nails compared to radiographs. The hypothesis will be that the larger the size of the osteophyte, the greater the nail curvature.
Nail curvature and osteophyte height will be measured in patients with clamp nails. Nail-phalange distance will also be measured with radiography and ultrasonography.
The investigators to find a positive correlation between nail curvature and osteophyte height. Furthermore, a strong agreement is expected between both imaging techniques to measure nail-phalange distance.
Ultrasonography could constitute a safe and effective alternative to radiology for detecting dorsal osteophytes in claw nails, especially in mild cases, follow-ups or young patients.
详细描述
Main objective:
The investigators aim to explore the possible relationship between the degree of dorsal curvature of the nail plate and the height of the dorsal osteophyte in subungual exostosis patients before and after surgery.
Secondary objectives:
The investigators will compare the distance between the nail surface and the dorsal cortex of the distal phalanx using plain radiographs and high-resolution ultrasonography.

结局指标
主要结局
Nail-phalange distance
时间窗: Pre-surgery, 2 months, 6 months.
The measurement of the minimum distance between the dorsal cortex of the distal phalanx and the ventral aspect of the nail of the first toe will be done using lateral radiographs and longitudinal ultrasounds. Lateral radiographs capture toe images from a side angle to determine the spatial relationship between the two points, with measurements expressed in millimeters. Longitudinal ultrasounds provide real-time images to visualize this relationship, with the ultrasound transducer placed along the toe. Both methods offer vital insights into toe anatomy for medical purposes like assessing deformities, tracking injuries, or planning surgeries.
