[Effectiveness analysis of limited small incision with simple Krackow suture in treatment of acute closed Achilles tendon rupture].

OBJECTIVE

To explore the effectiveness of limited small incision with simple Krackow suture in treatment of acute closed Achilles tendon rupture.

METHODS

Between October 2013 and July 2016, 25 cases with acute Achilles tendon rupture were repaired by simple Krackow suture via limited small incision. There were 21 males and 4 females with an average age of 33.6 years (range, 25-39 years). The left side was involved in 15 cases and the right side in 10 cases. The injury caused by sport in 22 cases and by falling in 3 cases. The time from injury to operation was 3-7 days (mean, 4.4 days). Physical examination showed that the Thompson sign and single heel raising test were positive.

RESULTS

The operation time was 30-60 minutes with an average of 39.2 minutes. All incisions healed by first intention. There was no complication of wound infection, deep vein thrombosis, tendon re-rupture, and sural nerve injury. All patients were followed up 9-20 months (mean, 14.2 months). The ankle and hindfoot score of American Orthopaedic Foot and Ankle Society (AOFAS) was 92-97 (mean, 94.9) after 9 months. The AOFAS score results were excellent in 13 cases, good in 9 cases, and fair in 3 cases. The range of motion of ankle joint was 49-58° with an average of 53.7°. All single heel raising tests were negative.

CONCLUSION

The method of simple Krackow suture via limited small incision has the advantages of minimal injury, less incidence of re-rupture and sural nerve injury, quicker recovery and so on.
