The hip joint is one of the largest weight-bearing joints in the body. This ball-and-socket joint allows the leg to move and rotate while keeping the body stable and balanced. Let’s take a closer look at the main parts of the hip joint’s anatomy.
This is a weakening and collapse of the bone in the head of your femur. That’s the ball that fits in the socket of your hip. As this bone gradually dies and breaks apart, you can develop painful arthritis in your hip.
This is an irritation or swelling of the trochanteric bursa. This small, fluid-filled sac is found on the outer side of the femur. It acts as a cushion for the iliotibial band, a thick tendon in your leg.
This is a problem with the hip joint. In a healthy hip, the ball of the femur is smooth and round. It fits perfectly into the hip socket. But with this condition, the ball, the socket or both the ball and the socket are shaped poorly. They don’t fit together well. When you move your […]
The hamstrings are three powerful muscles that travel along the back of your thigh. They are the semitendinosus, the semimembranosus and the biceps femoris muscles. They help bend your knee and extend your leg behind your body. Because these muscles handle high loads of stress, they are [...]
A broken hip is serious and disabling. With a broken hip, you may not be able to care for yourself. Sometimes, complications from a hip fracture can lead to death. Avoid a broken hip with these basic safety measures.
This is a break of the upper part of your femur. The femur is the long bone in your upper leg. At the top of the femur is the “head.” This is the ball that fits into your hip socket. A hip fracture may happen at the “neck” of the femur (the thin portion of […]
This is a problem on the outer side of your thigh. It’s an inflammation of the iliotibial band. That’s a thick band of tissue that spans from your hip to your shinbone. When this band becomes in inflamed, it can hurt.
This is a type of arthritis that can affect people of all ages. It’s not the same as the most common form of arthritis, called “osteoarthritis.” That type commonly comes from wear and tear. Inflammatory arthritis can develop without any wear and tear at all.
If your hip joint hurts, or if it catches or clicks when you move your leg, you may have a torn labrum. That’s a rim of tissue that surrounds the hip’s socket. It helps to deepen the socket and cushion the joint. A torn labrum can keep the hip joint from working smoothly.
Loose bodies are pieces of cartilage or bone of various sizes that have broken away and become trapped in a joint. Loose bodies usually have an irregular shape, but over time they may be worn down into a smooth, spherical or disc-shaped mass.
The hip is where the femur meets the pelvis. Several strong muscles are found here. They handle high loads of stress. They may suffer from overstretching and tearing. This is called a muscle “strain.” It’s a common injury among athletes who play sports that require sudden [...]
Your thigh has groups of powerful muscles. The quadriceps, the adductors and the hamstring muscles handle high loads of stress. They may suffer from overstretching and tearing. This is called a muscle “strain.” It is a common injury among athletes who play sports that require sudden [...]
This type of arthritis, also called “degenerative joint disease,” is a breakdown of the cartilage in your hip joint. As this protective cartilage wears away, bone rubs against bone. Bony growths called “bone spurs” may form in the joint. Pain from osteoarthritis can keep [...]
Osteoarthritis, also called degenerative arthritis, is a gradual breakdown of cartilage in the joints. Cartilage is a tough, flexible connective tissue that protects the ends of bones in the joints. Osteoarthritis is common in the hip because the hip bears the weight of the body. Osteoarthritis [...]
This serious injury is a break of a child’s thigh bone, called the femur. Because the femur is the largest and strongest bone in the body, this type of injury is relatively uncommon, accounting for only a small percentage of all pediatric fractures.
Your sacroiliac joints (we call them the “SI” joints) are the places where your hips meet your spine. These joints don’t have a lot of flexibility, but they do move slightly as you move your body. And if SI joints become damaged or diseased, it can be painful.
This is a problem with the head of the femur in growing children. With this condition, the ball-like head slips out of place in the hip socket. It moves down and back. This slip happens at the femur’s neck, along a growth plate. That’s where new bone develops. Growth plates are [...]
This is a strain or a tear of soft tissue. It often involves the muscles and tendons that travel from your lower abdomen to your pubic bone. A sports hernia does not create a hole in your abdominal wall. This injury can be difficult to diagnose, because it does not cause a bulge in your […]
This is a sudden loss of bone density in the head of the femur. That’s the ball that fits into the socket of your pelvis to form the hip joint. With transient osteoporosis, the femur’s head weakens and your hip begins to hurt.
