ObjectiveTo analyze the effectiveness and advantages of the microsurgical repair of flexor tendon rupture with non-knot Kessler suture method in anastomotic stoma by comparing with the method of traditional Kessler suture. METHODS; Between February 2005 and February 2010, 122 patients (163 fingers with 243 flexor digital tendons) with flexor tendon rupture, were treated with microsurgical repair by non-knot Kessler suture method (treatment group); flexor tendon was sutured, and sodium hyaluronate was used to repair tendon membrane, tendon sheaths, and the tissue surrounding tendons. The clinical data were analysed, and were compared with ones from 96 patients (130 fingers with 186 flexor digital tendons) with flexor tendon rupture treated with traditional Kessler suture between February 2001 and February 2005 (control group). There was no significant difference in gender, age, cause of injury, injury site, duration, and other general information between 2 groups (P > 0.05). Kleinert elastic traction therapy (dynamic-protection) was performed at 3 weeks after surgery, and the finger function exercise was done after 24 hours.ResultsInfection of incision occurred in 2 cases of the treatment group and in 5 cases of the control group, and were cured after 2 weeks of dressing change; the other incisions healed by first intention. The patients were followed up 6 to 14 months (mean, 9 months). In the treatment group, the total active movement (TAM) was (192.0 +/- 13.1) degrees; the results were excellent in 54 cases, good in 58 cases, moderate in 8 cases, and poor in 2 cases with an excellent and good rate of 92%. In the control group, TAM was (170.0 +/- 15.2) degrees; the results were excellent in 23 cases, good in 30 cases, moderate in 22 cases, and poor in 21 cases with an excellent and good rate of 55%. Significant difference in TAM was found between 2 groups (P < 0.01).ConclusionThe microsurgical repair of flexor tendon with non-knot Kessler suture method in anastomotic stoma with repair of tendon membrane, tendon sheaths, and the tissue surrounding tendons is more effective than the traditional Kessler suture, but long-term effectiveness still needs further observation.
