what is femoral neck
Femoral neck is the region connecting the shaft of the thigh bone (femur) to its rounded head, which fits into the hip joint (Picture 1).The femoral neck is potentially weak, because of its relatively smaller cross-sectional area and spongy bone tissue (cancellous bone).It is a part of the weight-bearing axis, which means that the weight of the entire body passes through it. Hence, it is the most frequently injured part of the thigh bone.he femoral neck, normally, forms an angle of 120-135 degrees with the shaft of the thigh bone (Picture 3). This acts as a lever in easing the action of the muscles around the hip joint. An increase or decrease in this angle beyond the normal limits causes improper action of the muscles, and interferes with walking.
