Hip bursitis, or trochanteric bursitis, is a condition marked by inflammation of the bursa near the hip joint, causing pain and discomfort in the outer hip area. The bursa is a fluid-filled sac that acts as a cushion to reduce friction between bones and soft tissues. When the bursa becomes inflamed, it leads to symptoms that can impact everyday movement and even sleep. Knowing the symptoms, causes, and effective treatments for hip bursitis can help individuals manage pain and promote healing.
Hip bursitis, or trochanteric bursitis, is inflammation of the greater trochanteric bursa, a sac located over the greater trochanter, the bony point on the outside of the hip. This bursa serves as a cushion between the greater trochanter and the tendons and muscles that pass over it, reducing friction and facilitating smooth movement.
When this bursa becomes irritated or inflamed, it results in trochanteric bursitis, causing pain and tenderness on the outer hip. Trochanteric bursitis is one of the leading causes of hip pain and is particularly common in individuals over 40, women, and those who frequently engage in high-impact activities. Additionally, people with conditions that place strain on the hip, such as arthritis or leg length discrepancies, are at higher risk of developing this condition.
The inflammation can either be acute (sudden and short-term, typically due to injury) or chronic (long-term, caused by repetitive strain or underlying conditions). Proper diagnosis and treatment are essential to manage symptoms and prevent the condition from becoming chronic.
Several factors contribute to the inflammation of the hip bursa. Common causes include:
Hip bursitis often occurs in individuals who engage in repetitive activities that place stress on the hip joint, such as running, cycling, or stair climbing. These activities create continuous friction between the bursa and surrounding tissues, leading to inflammation. Over time, this repetitive stress weakens the bursa, making it more susceptible to irritation. Athletes and individuals with physically demanding jobs are at higher risk.
Direct trauma, such as a fall or impact to the outer hip, can cause sudden irritation and inflammation of the bursa. This form of bursitis is often acute and develops soon after the injury. Even if the skin is unbroken, the impact can cause bleeding and swelling within the bursa, leading to pain and tenderness.
Poor posture or body mechanics, such as standing with weight unevenly distributed or sitting with crossed legs, can strain the hip bursa. Even habits like frequently carrying heavy bags on one side of the body can cause imbalanced strain on the hip joint, increasing the risk of bursitis.
Hip arthritis, particularly osteoarthritis and rheumatoid arthritis, is a common underlying condition associated with bursitis. Arthritis causes inflammation within the joint, which can spread to nearby structures like the bursa. Arthritis also leads to increased friction and instability in the joint, making the bursa more prone to irritation.
When one leg is longer than the other, it creates an imbalance that affects how the hip joint functions. This imbalance places extra stress on the hip, forcing the body to compensate and leading to repetitive strain on the bursa. Over time, this condition can lead to chronic bursitis if left untreated.
Weakness in the muscles surrounding the hip, particularly the gluteus medius and gluteus minimus, can alter hip mechanics. Muscle imbalances place additional strain on the bursa, increasing the likelihood of inflammation. Physical therapy exercises can help address these imbalances and relieve stress on the bursa.
Calcium deposits or bone spurs can form within the tendons around the hip joint, rubbing against the bursa and causing inflammation. These deposits may be associated with other degenerative joint conditions and increase the risk of bursitis by creating additional friction in the hip area.
The symptoms of hip bursitis can range from mild discomfort to severe pain, depending on the level of inflammation. The most common symptoms include:
The hallmark symptom of hip bursitis is pain on the outer side of the hip, near the greater trochanter. This pain can vary in intensity, from a dull ache to a sharp, stabbing sensation. Pain may radiate down the thigh and is typically felt more when pressing on the hip or lying on the affected side.
Physical activities that involve repetitive hip movements, such as walking, running, or climbing stairs, can exacerbate the pain. Many individuals find that their symptoms worsen with any movement that involves weight-bearing on the affected side, especially after prolonged activity.
Tenderness around the outer hip area is common with hip bursitis, and some people may experience swelling if the inflammation is severe. The area may also feel warm to the touch, a sign of active inflammation, and prolonged physical activity may exacerbate this swelling.
Inflammation in the bursa can lead to stiffness, making it challenging to move the hip comfortably. Everyday tasks, such as bending over, stretching, or sitting cross-legged, may feel uncomfortable due to the limited range of motion.
Many people with hip bursitis report that pain worsens at night, especially when lying on the affected side. This can disrupt sleep and affect overall quality of life, making it challenging to find a comfortable position in bed.
In some cases, pain may extend from the hip down the side of the thigh, creating symptoms that mimic sciatica. This radiating pain can vary in intensity and may occur when the hip is moved or with prolonged sitting.
Hip bursitis, or trochanteric bursitis, is inflammation of the greater trochanteric bursa, a sac located over the greater trochanter, the bony point on the outside of the hip.
Hip bursitis can be caused by repetitive stress, injury, poor posture, arthritis, leg length discrepancies, muscle weakness, and calcium deposits or bone spurs.
Common symptoms include outer hip pain, increased pain with activity, tenderness, swelling, stiffness, limited mobility, nighttime pain, and radiating pain down the thigh.
