摘要： A self-retaining screwdriver having a plurality of diametrically opposed, radially extending blades on its tip for engagement with corresponding slots of a screw or other fastener, wherein the blades vary radially in thickness. The screwdriver also includes diametrically opposed, radially extending blades of constant thickness arranged perpendicular to the blades of radially varying thickness. Tapered blades having a thickness which increases with distance from the screwdriver axis are disclosed in one embodiment in which the blades also have a convex end surface, for use with a screw having a convex head.

摘要： A system for mandibular reconstruction generally includes an elongated locking plate having a plurality of internally threaded apertures and a plurality of fasteners. Each fastener includes a main body portion having an upper threaded shaft and a lower threaded shaft. The lower threaded shaft is adapted to engage the mandible. Each fastener further includes a removable head portion internally threaded for engaging the upper shaft portion and externally threaded for engaging a selected one of the internally threaded apertures of the locking plate. In the preferred embodiment, the thread leads of the head portion and lower shaft of the main body portion are identical. A method of mandibular osteosynthesis utilizes the system of osteosynthesis and generally comprises the steps of temporarily securing the elongated locking plate to the mandible with at least one fastener by engaging the threads of the lower portion with the mandible and threadably engaging the head with the locking plate, unthreading the head portion from the main body of the fastener to thereby allow displacement of the locking plate from the mandible without removing the fasteners from the mandible, performing a surgical procedure (e.g., removal of a cancerous growth), and re-securing the elongated plate to the fastener with the removable head portion.

摘要： An elongated plate for coupling severed bone regions comprising at least one bridge region, the at least one bridge region terminating in at least two bone fixation regions. The at least two bone fixation regions each contain at least one aperture for receiving a suitable fastening device for securing the elongated plate to the bone regions to be coupled. The bridge region may be configured so as to be easily severed by a suitable severing device such as surgical scissors. The elongated plate and fastening device may be formed from a bio-compatible or bio-resorbable material.

摘要翻译： 用于下颌重建的系统通常包括具有多个内螺纹孔和多个紧固件的细长锁定板。 每个紧固件包括具有上螺纹轴和下螺纹轴的主体部分。 下螺纹轴适于接合下颌骨。 每个紧固件还包括可旋转的头部部分，其内螺纹用于接合上轴部分并且用于接合锁定板的内螺纹孔中的所选一个的外螺纹。 在优选实施例中，主体部分的头部和下轴的螺纹线相同。 一种下颌骨合成术的方法利用了骨接合术系统，并且通常包括以下步骤：通过将下部的螺纹与下颌骨接合并将头部与锁定板螺纹接合，将细长的锁定板临时固定到具有至少一个紧固件的下颌骨 使头部从紧固件的主体脱开，从而允许锁定板从下颌骨移位而不从下颌骨移除紧固件，执行外科手术（例如，去除癌性生长），并重新固定 拉长板到具有可拆卸头部的紧固件。

摘要： A method and apparatus for performing pectus excavatum repair on a deformed sternum. The apparatus includes an elongated pectus bar having a first end and a second end. The elongated pectus bar provides a minimum bendable strength of about 65 in-lbs or a minimum material yield strength of 35.times.10.sup.6 psi or a minimum bendable stiffness of about 1000 lb-in.sup.2. The elongated pectus bar is shaped into a convexly curved pectus bar. The convexly curved bar is passed under the deformed sternum with the convexity facing posteriorly. The elongated pectus bar is then rotated so that the convexity faces anteriorly such that the deformed sternum is raised into a desired position.

摘要： A method according to the present disclosure may include determining a load to be supported across separated bone regions by a bridge region of a bone plate. The method may further include determining an acceptable cut force (CF) for the bridge region, determining a cross-sectional area (a) of the bridge region based on the determined load, and determining a height (h) and a width (w) of the bridge region. A bone plate may be provided including a bridge region having the height (h) and width (w) for securing the separated bone regions.
