[Ultrasound-guided minimal traverse-cross technique repair for acute closed Achilles tendon ruptures]

To explore clinical effects of ultrasound-guided minimal traverse-cross technique repair for acute closed Achilles tendon ruptures.

From January 2015 to March 2017, 20 patients with acute closed Achilles tendon rupture were treated by minimal traverse-cross technique repair with ultrasound guided. Among them, including 13 males and 7 females, aged from 28 to 49 years old with an average of(31.3 ±4.5) years old. All patients were single side injury. Fifteen patients on the left side and 5 patients were on the right side. The time from injury to operation ranged from 1 to 5 days with an average of (2.5±0.7) days. Operative time, postoperative complications were observed, and AOFAS score before and after operation at 12 months were compared.

All patients were followed up for 12 to 27 months with an average of(15.2±4.9) months. Operative time ranged from 33 to 65 min with an average of(43.7±5.6) min. Incision of one patient were continued oozing and improved after changing dressings, other patients were healed at stage I. No sural nerve irritation symptoms and palindromic rapture of heel tendon occurred. AOFAS score was improved from 65.2±7.4 before operation to 97.7±4.7 after operation at 12 months (t=22.5, P<0.01); 18 patients got excellent results and 2 good.

Ultrasound-guided minimal traverse-cross technique repair for acute closed Achilles tendon ruptures, which promise minimal incision, protect sural nerve, ensure quality of tendon anastomosis and fixation, and is a ideal method for repairing acute closed Achilles tendon ruptures.
