WHAT IS TROCHANTERIC BURSITIS?
Trochanteric bursitis is defined as pain over the bony prominence of the upper lateral thigh due to inflammation of the bursa. The bursa lies between the greater trochanter and the overlying musculature.
WHAT IS A BURSA?
A bursa is a small fibrous sac lined with synovial membrane and containing synovial fluid. A bursa acts as a cushion between the tendon and the bone in order to reduce friction during joint movement, especially in running.
COMMON SIGNS AND SYMPTOMS
Common symptoms of trochanteric bursitis include;
Pain over the lateral aspect of the hip with pain radiating down the lateral aspect of the thigh
Pain +/- giving way walking up and down stairs
Unable to lie on painful hip
Pain with running
Pain with sit to stand/squatting/kneeling
Trendelenburg sign (weakness in gluteals)
Lumbo-pelvic musculature imbalances
Abnormal running gait
HOW DO YOU GET TROCHANTERIC BURSITIS?
Trochanteric bursitis usually results from poor muscular control causing compression from the associated muscles, bands and fascia on to the bursa. This is commonly experienced in overuse activities such as running, which most people display an abnormality in their running gait. Other causes of trochanteric bursitis include;
Trauma directly to the bursa
Post hip surgery
Post hip joint replacement
Trochanteric bursitis is relatively common in both the physically active and sedentary population. Women are 80% more likely to develop trochanteric bursitis than Men with a prevalence of 15% compared to 8.5%.
In overuse trochanteric bursitis, there are a number of predisposing factors. These factors include;
Larger ‘Q’ angles
Weak gluteal muscles
Lumbo-pelvic muscular imbalances
Bike Set up
Leg length discrepancy
Treatment initially includes reducing inflammation with Physiotherapy, ice, analgesics, NSAID’s and possibly corticosteroid injections. Physiotherapy involves identifying and removing the predisposing factors in which the pain was first triggered by.
Other differential diagnoses around the lateral hip can include;
Gluteus medius tendinopathy
Gluteal tendon strains
Although these conditions may look the same and feel the same from the outside, the management and cause of injury can differ.
