Provided is a femoral support member (3) for a walking assistance device that includes a power actuator (actuator 4) having a drive shaft and secured to a hip region of a wearer, the femoral support member securing a free end of an assist force transmitting arm (5) extending from the drive shaft of the power actuator to a femoral region (T) of the wearer. The femoral support member engages the femoral part of the wearer via an air pad (27) filled with air. Thus, owing to the air cushioning action of the aid pad, the air pad can readily deform itself by a large displacement even when the wearer squats and the femoral region expands. By appropriately adjusting the air in the air pad, the femoral support member can be worn by a wearer in a highly favorable manner.

The invention discloses an osteophyte recognition method and device, electronic equipment and a storage medium. The osteophyte recognition method comprises the following steps: acquiring a medical image; inputting the medical image into a trained first segmentation model to obtain a femur region and/or a tibia region and/or a fibula region and/or a patella region in the medical image; and inputting the femur region and/or the tibia region and/or the fibula region and/or the patella region into a trained second segmentation model to obtain a femur osteophyte and/or a tibia osteophyte and/or a fibula osteophyte and/or a patella osteophyte. Accordingly, the osteophyte can be quickly, accurately and intelligently identified by utilizing the first segmentation model and the second segmentation model. Doctors can be assisted in surgical planning, operation is easy, accuracy is high, and individual differences of patients can be met, and meanwhile, the accuracy of follow-up surgeries can be improved and a large amount of time can be saved for orthopedists by perfecting basis data of preoperative planning and guiding surgical planning and prosthesis selection.
