What Bone Receives the Weight of the Body When Sitting

Many bone problems arise from sitting for long periods. For instance, the femoral neck can narrow, leading to more blood clotting and plaque buildup.

It’s hard to find a comfortable position when sitting because the bones don’t support the weight properly. You might be wondering what bone bears the most weight when sitting? Is the weight of the body distributed in a variety of ways when we sit?

What bone bears the most weight when sitting?

The posterior margin of the ilium has a large greater sciatic notch, while the posterolateral portion is referred to as the ischium. It has an expanded ischial tuberosity, which functions when sitting. The ischial ramus extends anteriorly from this bone and supports weight when sitting.

The ischial tuberosity or “sit-bone” can be found on the ischium, on the top of the femur. It marks the limit of your range of motion when bending your leg.

The ischial tuberosity is often confused with the coccyx, which is the tailbone at the bottom of the spine. Though they are connected, they are not the same. The ischial tuberosity sits at the front of your pelvis and serves as a point of attachment for muscles that run to your thigh. It also carries some weight when seated.

The posteroinferior region of the hip bone is a narrow segment of bone that projects superiorly and anteriorly from the ischial tuberosity. It is often called the posterior iliac spine.

It supports the body when sitting. The runs from the sacrum to the ischial tuberosity. These ligaments help to support and immobilize the sacrum as it carries the weight of the body.

The sacrum is the base of the spine. It has a triangular shape, and it is wider in front than at its back. The sacrum connects to the hipbones, which are also called pelvis bones, by different parts of the sacroiliac joint. The ligaments that support and stabilize the sacrum are called “sacroiliac ligaments.”
