Abstract

Tendoachilles rupture has recently seen an increase in frequency, accounting for up to 40% of all tendon ruptures. However, an acute segmental rupture of the Achilles tendon is very rare with only one case caused by predisposing factors, such as steroid injection. In this report, we highlight an unusual clinical presentation of a segmental rupture of the Achilles tendon without any underling predisposing factor and without direct trauma. Herein, we discuss its mechanism. Twelve months after surgical repair with open technique, this patient became fully functional again in daily activity.

  Figure 1 The preoperative radiograph shows 2 cm sized avulsion fragment located 3 cm above the upper margin of calcaneal tuberosity and loss of Kager's triangle.

• 

  Figure 2 The preoperative sagittal magnetic resonance imaging shows tear of the Achilles tendon at 6 cm proximally from calcaneal insertion site (arrow) and the superficial fiber rupture of Achilles tendon combined with avulsed fracture fragment (asterisk).

• 

  Figure 3 Intraoperative photographs of the Achilles tendon shows about 80% partial tear of the Achilles tendon at 6 cm proximally from calcaneal insertion site (arrow) and the superficial fiber rupture of Achilles tendon combined with avulsed fracture fragment (asterisk).

  Figure 4 (A) Achilles segmental rupture was respectively repaired by Krackow method and suture bridge technique. (B) Paratenon was completely repaired. (C) Postoperative radiograph.
