Intra-articular and peri-articular pain can be caused by myriad of conditions. Some are generic and can affect any joint, such as inflammatory arthritis. Some are specific to the processes within a particular joint or region, for example: Shoulder; pain commonly caused by the process of impingement – injection to the subacromial bursa.Elbow; pain commonly caused by ‘tennis’ or ‘golfer’s’ elbow – injection into the common extensor or flexor origins respectively.Wrist; pain commonly caused by de Quervain’s tenosynovitis – injection into the tendon sheath of the first extensor tendon.Hip; pain commonly caused by trochanteric bursitis – injection into the region of the trochanteric bursa.

Trochanteric Bursitis is an extremely common disorder caused due to trauma or excess physical activity viz running or jumping due to which the greater trochanteric bursa gets inflamed. The inflamed bursa gets sore due to the movements between the wider trochanter and the overlying iliotibial band. The patient experiences weight-bearing discomfort on one leg due to the tightening of the iliotibial band in an attempt to preserve the upright posture. The patient may also express an inability to lie on the affected side. Tenderness with over palpation on the wider trochanter and discomfort with avoided hip invasion is observed during physical examination. Nonsteroidal anti-inflammatory drugs, steroid injections are used to reduce the pain caused by trochanteric bursitis. Assistive devices like cane or crutches can also be used to avoid applying complete load on the hip during its healing.

The femur is the longest, largest and strongest bone in the body as shown in Figure 1. It spans from the hip joint, where it articulates with the pelvis, to the knee joint, where it articulates with the tibia and patella. The femur broadly consists of proximal and distal extremities joined by an almost cylindrical shaft. For hip fracture research purposes, we are mainly interested in the proximal femur, encompassing the proximal (superior) extremity and the top portion of the shaft. The most proximal portion of the femur is the femoral head, a spheroidal section of bone covered with cartilage that slides against the acetabulum in the pelvis. The femoral neck is a longitudinally concave cylinder that connects the femoral head to the shaft. The greater trochanter (GT) is a large protuberance that forms the most lateral and palpable portion of the femur. It serves as the point of attachment for several muscles that connect the femur to the pelvic bone. The lesser trochanter is a smaller feature protruding from the posteromedial shaft, just inferior to the GT.
