Ultrasound-assisted calcaneoplasty.
OBJECTIVE
The endoscopic technique for resection of a postero-superior part of calcaneus served as a golden standard during the last 10 years, and it has mostly replaced the open techniques. In an effort to reduce the morbidity and the recovery time, we had introduced the ultrasound-assisted technique.


METHODS
In the period of 1 year, 15 patients with the prominent postero-superior part of calcaneus and retrocalcaneal bursitis were operated through the single skin incision using the ultrasound-assisted technique. The prominent part of calcaneus was resected with a bone abrader under the ultrasound control to the point when there was no impingement between Achilles tendon and calcaneus in maximal dorsal flexion. The patients were evaluated preoperatively and postoperatively with the AOFAS score and Ogilvie-Harris score. The strength test of the muscle triceps surae, as well as the proprioceptive test, was also undertaken.


RESULTS
Initially, the follow-up was meant to last 6 months, but there were no differences in results between 6 weeks and 3 months postoperatively, so it was concluded that the 3-month follow-up is sufficient and relevant. All 15 patients were available for follow-up. All measured variables significantly improved (AOFAS, Ogilvie-Harris), and all the patients were satisfied with the postoperative result. Only one minor complication occurred: superficial infection.


CONCLUSIONS
The ultrasound-assisted calcaneoplasty enables a precise resection of the postero-superior part of calcaneus and removal of the retrocalcaneal impingement. This method could become clinically relevant as it enables effective treatment of Haglund deformity, and results of this study presented rapid functional recovery.
