Ultrasonographic evaluation of the effect of extracorporeal shock wave therapy on calcific tendinopathy of the rectus femoris tendon: A case report

초록

BACKGROUND Calcific tendinopathy denotes calcific deposits in a specific tendon. It is also known as calcifying tendinitis, calcifying periarticulitis, or periarticular apatite deposition disease. Recently, extracorporeal shock wave therapy (ESWT) has been reported to be effective in relieving and treating pain in calcific tendinopathy. CASE SUMMARY A 36-year-old female patient suffered from left hip joint pain for six months. The pain was increased during abduction of the hip, waking, and jumping. B-mode ultrasonography was performed by a physiatrist with an L12-5 linear transducer. A single session of ESWT was given in the marking area under ultrasound guidance at 4 Hz, 2500 shots with intensity of stimulation using energy of 0.1 mJ/mm(2). The hip pain of the patient slowly decreased within 4 wk after starting the ESWT. After six weeks of ESWT, her hip pain was completely resolved. However, the size of calcification showed almost no reduction in simple radiography at the final follow-up. CONCLUSION Ultrasonography is a very good modality not only for diagnosing calcified tendinitis by classical appearance, but also for evaluating the effect of ESWT during the follow-up period.
