Trochanteric bursitis, otherwise known as ‘Greater Trochanteric Pain Syndrome’ describes the painful inﬂammation of a small cushion-like sac called a bursa that sits over a bony prominence called the greater trochanter on the side of the hip on the femur (thigh bone). Because bursae function to reduce friction between muscles/tendons and bone and facilitate movement, inﬂammation occurs when these tissues rub against the bursa and cause friction. This can occur through sporting injuries or falls, or may occur with repeated stress over time such as through walking, running and cycling. Symptoms include pain at the hip that may radiate down the thigh, swelling at the side of the hip, pain on standing after prolonged sitting and increased pain on prolonged repetitive movement such as walking. Typically pain is felt on pressing on the outside of the affected hip.
Hip Labral Tear/Impingement
A hip labral tear describes a tear in the cartilaginous ring surrounding the socket of your hip joint that otherwise functions in cushioning and stabilising the hip socket. Various causes include sporting and accidental trauma that results in displacement of the hip into an abnormal position, repetitive abnormal hip rotation such as during hockey, ballet, soccer and golf, and structural abnormalities within the joint. Occasionally no pain is felt from a labral tear but when symptoms are present they include pain in the outer hip and groin regions, a catching or clicking feeling in the hip joint, stiffness and limited movement at the joint.
A hip labral impingement, otherwise known as ‘Femoroacetabular Impingement’ (FAI), describes an irregularity in the shape of the bones of the hip joint due to bone spurs which causes abnormal rubbing and friction during movement as a result of the imperfect shape. This occurs either from birth or from irregular development of the hip bones in childhood and adolescence and causes pain, swelling and poses an increased risk of early hip osteoarthritis.
