To provide trousers that suppress discomfort when bending forward and reduce strain on the lower back in a bent-over posture without being conspicuous. [Solution] The waist portion 20, formed at the upper end of the trouser body and tightened by a belt, surrounds the pelvis 200 at the height of the anterior superior iliac spines 202a and 202b, and has an elastic belt 24 to adjust the length in the waist direction. The front region α of the waist portion 20 on the abdominal side 101 of the wearer 100 has a rigidity of 25.7 mN or more, measured in accordance with the Gaarle method specified in JIS L1096 (2010), and is set to a width of 4.0 cm or more and 13.0 cm or less, and its thickness T1 is set to be thicker than the rear region β on the back side 102 of the wearer 100, and the left side region γ1 and right side region γ2 between the front region α and the rear region β, and is set to be less than 14.0 mm.

To provide an absorbent article for improving wearing comfort.SOLUTION: An absorbent article includes: a front body region located on a front side of the wearer in the front-back direction; a back body region located on a back side of the wearer; a crotch region that has a crotch-region central part between the front body region and the back body region, and whose width is narrower than the front body region and the back body region; a buttocks-corresponding region corresponding to the wearer's buttocks, located in a region 145 mm to 314 mm on the back side from the crotch-region central part; and an absorber having a lower-layer absorbent mat extending at least from the crotch region to the buttocks-corresponding region, and an absorbent mat extending forward of the buttocks-corresponding region, having a width longer than the width of the crotch-region central part, and disposed on a skin surface-side of the lower-layer absorbent mat in the crotch region, where the crotch-region central part is located 145 mm from the back-side end of an upper-layer absorbent mat.SELECTED DRAWING: Figure 3

This invention relates to a prosthesis for implantation between vertebrae. Specifically, it discloses an intervertebral fusion device with built-in anchoring elements, comprising: a fusion device body having two end faces, an anterior wall and a posterior wall, two side walls, and a bone graft window; each side of the bone graft window of the fusion device body has two first linear channels extending from the anterior wall and penetrating to the posterior region of the end face, and two second linear channels extending from the posterior wall and penetrating to the anterior region of the end face; an anchor rod pre-positioned in the linear channels; and an actuation mechanism including an operating head exposed on the anterior wall of the fusion device body and an actuating body located in the fusion device body for driving the anchor rod. By turning the operating head, the actuating body drives the anchor rods in the first and second linear channels to extend obliquely forward from the posterior and anterior regions of the end faces, respectively, under the guidance of their respective linear channels, and insert them into the vertebrae through the endplate.

To provide a partial knee implant and a method for installing the same.SOLUTION: The present disclosure is a femoral preparation guide and a kit of surgical components related to the femoral preparation guide. The femoral preparation guide is for use on a condyle of a femur during a surgical procedure in which the condyle receives a femoral condyle implant. The femoral preparation guide includes a posterior portion for fitting over a posterior region of the condyle and a distal portion for fitting over a distal region of the condyle. The distal portion is angled relative to the posterior portion. The distal portion includes first and second resection slots for receiving cutting tools that provide two resections of the condyle. The first and second cutting slots are angled relative to each other.SELECTED DRAWING: Figure 1C

This invention discloses an artificial intelligence-based automatic four-zone segmentation and measurement system for calcaneal fractures, relating to the field of three-dimensional image analysis technology. The method acquires the DICOM sequence of foot and ankle CT scans, converts it into NIfTI three-dimensional volume data, and performs voxel resampling, bone window normalization, and orientation standardization. A first segmentation network extracts a complete three-dimensional mask of the calcaneus, establishes a three-dimensional anatomical coordinate system, and clips the region of interest (ROI) of the calcaneus. A second segmentation network generates four-zone probability maps: the anterior region, the posterior region, the superior articular surface-related region, and the medial support region. The spatial assignment of structural blocks is determined by constraints from the complete calcaneal three-dimensional mask, connected component analysis, and the centroid and anchor point projection of the structural blocks. Finally, based on the complete calcaneal contour and the four-zone label map, geometric angles, surface height differences, the number of effective connected components, and the three-dimensional contact ratio are extracted and encapsulated into structured parameter files and quality control markers for easy three-dimensional display and image retrieval.
