摘要

骶髂螺钉固定包括使用空心、部分或全螺纹螺钉。目前的部分螺纹螺钉具有标准化的螺纹长度，涉及螺钉的一小部分，而不考虑其整体长度。40张未损伤的计算机断层图像评估了从髂外侧皮质到骶外侧皮质在第一和第二骶节的距离。没有观察到性别、年龄或体重指数的测量差异。使用32毫米的平滑段值，可以实现螺纹长度的显著增加，从而允许新的骶髂螺钉设计，以实现更大的骶骨购买量。

Can Partially Threaded Cannulated Screws Be Better Designed to Maximize Purchase in the Sacrum?

Sacroiliac screw fixation involves the use of cannulated, partially or fully threaded screws. Current partially threaded screws have standardized thread lengths involving a small portion of the screw regardless of its overall length. Forty uninjured computed tomography images were evaluated for distances from the lateral iliac cortex to the lateral sacral cortex at the first and second sacral segments. No difference in measurements were observed for gender, age, or body mass index. Using a smooth segment value of 32 mm, a significant increase in thread lengths is achievable allowing for a novel sacroiliac screw design to achieve greater purchase in the sacrum.

期刊介绍： MEDICAL IMPLANTS are being used in every organ of the human body. Ideally, medical implants must have biomechanical properties comparable to those of autogenous tissues without any adverse effects. In each anatomic site, studies of the long-term effects of medical implants must be undertaken to determine accurately the safety and performance of the implants. Today, implant surgery has become an interdisciplinary undertaking involving a number of skilled and gifted specialists. For example, successful cochlear implants will involve audiologists, audiological physicians, speech and language therapists, otolaryngologists, nurses, neuro-otologists, teachers of the deaf, hearing therapists, cochlear implant manufacturers, and others involved with hearing-impaired and deaf individuals.
