The hip is one of the most stable joints in the body. But, its function, bearing the body’s weight, makes it susceptible to arthritis due to excessive pressure and bone fractures. Hip pain is common for people of all ages. Workers, athletes, and active people who rely on their hips daily are more likely to injure them, especially from overuse.
The location of pain can vary significantly depending on the source that is causing it. Problems within the hip joint itself usually lead to pain on the inside of your hip or your groin. Pain in and around the hip may also result from injury to the surrounding muscles, tendons, or bursae (small fluid-filled sacs that cushion and lubricate joints).
Sometimes, hip pain can be caused by diseases and conditions in other areas of your body, such as your lower back, a condition called referred pain. You can even feel pain that originates in the hip from your leg down to your knee and in your buttocks.
The doctors and clinical team at Main Line Spine provide comprehensive diagnostics and non- and minimally-invasive treatments for a wide range of hip conditions. Our team includes experts across a broad spectrum of musculoskeletal and neurologic disorders – with a focus on relieving pain and restoring function and mobility – without the need for major surgery.
Common Causes of Hip Pain
Many different conditions and injuries can cause hip pain. Some of the more common ones include:
Arthritis
Arthritis is the most common cause of the breakdown of hip tissue. Three kinds of arthritis commonly affect the hip:
- Osteoarthritis – Also known as degenerative joint disease, this is the most common type of arthritis. It occurs when the protective cartilage that cushions the ends of your bones gradually breaks down over time, causing the bones to rub against each other, causing hip pain and stiffness.
- Post-Traumatic Arthritis – This is a common form of osteoarthritis that occurs due to a physical injury to any kind to a joint. It is often the result of an injury or fracture that changes the mechanics of the hip joint, making it wear out more quickly as a result.
- Rheumatoid Arthritis – This is an autoimmune disease, that attacks the hip joint capsule’s lining, known as the synovial membrane. It causes it to become inflamed and swollen. This disease process can eventually destroy cartilage and bone within the joint, leading to pain and stiffness.
Bursitis of the Hip
The bursae are small, fluid-filled sacs that cushions the bones, tendons, and muscles near your hip joint. Bursitis of the hip causes pain in the hip when a bursa becomes irritated or inflamed.
There are two major bursae of the hip, both of which can be associated with stiffness and pain around the hip joint.
- The Trochanteric Bursa is located on the side of the hip and separated significantly from the actual hip joint by tissue and bone. Bursitis in this bursa frequently causes pain and tenderness in the outer hip and thigh, making it difficult for those affected to lie on the involved side, causing difficult sleep.
- The Ischial Bursa is located in the upper buttock area. Bursitis in this bursa can cause dull pain that is most noticeable when climbing uphill, or after prolonged sitting on hard surfaces.
Avascular Necrosis
Avascular necrosis is a disease that results from the temporary or permanent loss of blood supply to the bone. Without an adequate blood supply, bone tissue starts to die, and as it loses its structural integrity, tiny breaks called microfractures begin to form.
These microfractures can cause the collapse of the weight-bearing surface of the bone, causing pain. If the bone affected is near a joint, the joint may also collapse.
Hip Pointer
A hip pointer is a deep bruise to the ridge of bone on the upper outside of your hip, called the iliac crest. It’s often a result of a direct blow to the hip or a hard fall.
