Before proceeding to any interventional procedure, a detailed imaging examination of the affected area should be performed. This may include ultrasound, xray or MRI.
Where a thickened bursa is present, a steroid and local anaesthetic injection using ultrasound guidance is a precise option for treatment. The benefit of using ultrasound is that this gives a real time visualisation of the needle as it enters the bursa.

The benefit for this patient was a significant decrease in pain and significant increase in the range of movement.
This patient presented with trochanteric bursitis. There is a lot of adipose tissue to penetrate making accurate placement of the needle difficult. However, under ultrasound accurate placement of the needle was achievable.

With this level of accuracy, patients are less likely to be subject to painful repositioning. of the needle. Also the free passage of steroid and local anaesthetic around the bursa can be observed in real time. Skilled professionals are able to perform these injections easily with great accuracy . Therefore, the benefits to patient care are clear to see.
