Objective:
To investigate the effectiveness of modified suture technique in the treatment of acute closed Achilles tendon rupture.
Methods:
Between December 2013 and December 2016, 29 cases with acute closed Achilles tendon rupture were treated with modified suture technique. There were 23 males and 6 females with an average age of 34 years (range, 22-45 years). All patients were sport injuries. The injury located at left side in 22 cases and right side in 7 cases. American Foot and Ankle Surgery Association (AOFAS) ankle and hind foot function score was 44.6±3.6. According to the Amer-Lindholm criteria, 29 cases were rated as poor. MRI showed the complete rupture of the Achilles tendon.
Results:
The operation time was 35-62 minutes (mean, 46 minutes). The intraoperative blood loss volume was 7-15 mL (mean, 10 mL). The incisions healed by first intention, and no sural nerve injury occured. All patients were followed up 5-38 months (mean, 18.4 months). AOFAS ankle and hind foot function score was 93.1±4.3 at 3 months after operation, showing significant difference when compared with the preoperative value ( t=-49.581, P=0.000). According to the Amer-Lindholm criteria, the results were excellent in 24 cases and good in 5 cases, and the excellent and good rate was 100%; there was significant difference between pre- and post-operation ( Z=-7.294, P=0.000). MRI showed the continuous and integrity of Achilles tendon. No Achilles tendon rupture recurred during the follow-up period.
Conclusion:
Modified suture technique in the treatment of acute closed Achilles tendon rupture owns the advantages of less trauma, lower recurrence rate of rupture, lower risk of the sural nerve injury, and satisfactory function recovery.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
