Abstract
INTRODUCTION: During arthroscopy, the localization of calcific deposit in patients suffering from calcifying tendinitis can be demanding and time consuming, frequently using ionizing radiation. Intraoperative ultrasound has been recently promoted, facilitating deposit localization and reducing radiation dose. MATERIAL AND METHODS: In this prospective, randomized, controlled and clinical observer-blinded pilot trial, 20 patients with calcific tendinitis were operated. In group I, the deposit was localized conventionally. In group II, the deposit was localized using intraoperative ultrasound. The needle punctures to detect the deposit and operation times were noted. Patients were postoperatively evaluated after 2 and 6 weeks and 9 months. RESULTS: In group II, the needle punctures to detect the deposit were significantly lower than in group I (p < 0.0001). Operation time to localize the deposit was also significantly less in group II (p < 0.033). In both groups, patients improved significantly with increased shoulder function (p < 0.0001) and decreased pain (p < 0.0001) 2 weeks and 9 months (p < 0.001) after surgery. The difference between the groups was not significant. Excellent radiological findings were obtained in both groups after 9 months. CONCLUSIONS: Intraoperative US significantly facilitates the detection of calcific deposits during arthroscopic debridement by speeding up surgery and reducing the number of needle punctures. Hence, we have changed our method of detecting calcific deposits intraoperatively from fluoroscopy to ultrasound.
