The present invention relates to a system and a method for bone fracture risk assessment and provides for a system to predict Osteoporosis and Osteopenia and its associated fracture risk automatically from conventional chest X-ray image. The invention provides an automated digital X-ray bilateral Clavicle Radiogrammetry and its estimation of Cortical Thickness and Calculation of Cortical bone mass indices of Clavicle to predict dual Hips (Neck) Bone Mineral Density (BMD), dual Hips (Total) Bone Mineral Density (BMD) and Spine (Total) Bone Mineral Density (BMD) as measured by dual energy X-ray absorptiometry (DXA) bone densitometer and 10-year probability of both Major Bones (hip, spine, humerus or forearm)—and Hip-Osteoporotic Fracture Risk Scores. Using the same chest X-ray, an automated prediction of Osteoporosis and Osteopenia at both dual hips and spine regions and 10-year probability of both Major Bones and Hip Osteoporotic Fracture Risk using Artificial Intelligence (AI).

A medical device configured to form one or more holes in a patient's bone includes a handle assembly including a housing, a shaft rotatably coupled to the housing, and a sheath extending distally from the housing, the handle assembly including a spring biasing the shaft toward an initial or intermediate position; and a bone punch including an elongated shaft, a head at a proximal end of the elongated shaft, and a piercing tip at a distal end of the elongated shaft, the piercing tip configured to be driven into the bone. The elongated shaft is slidably disposable within the sheath in a first position when the shaft is in the initial or intermediate position. Distal translation of the bone punch within the sheath from the first position to a second position can cause a distal end of the shaft to rotate away from the housing to an extended position.

This invention discloses an automatic bone densitometer localization method based on multimodal sensing and AI contour matching. The method uses a multimodal sensing module to collect data on the patient's three-dimensional contour, body thickness distribution, respiratory micro-movements, and dynamic displacement. After preprocessing and fusion to generate a feature map, an improved U-Net++ model and ICP registration algorithm are used to achieve precise segmentation and registration of the bone contour. Hardware-based collaborative calibration, dynamic tracking compensation, and error correction are then employed to achieve automated, high-precision localization of the target bone. This method reduces reliance on patient cooperation, achieves a localization accuracy of ≤0.3mm, a process time of ≤10 seconds, and low radiation dose. It is suitable for special populations such as the elderly, children, and those with scoliosis, as well as complex clinical scenarios, significantly improving the efficiency, accuracy, and safety of bone density testing.
