[The clinical study of adhesion prevention of sodium hyaluronate in flexor tendon surgery].

OBJECTIVE: To evaluate the effects of sodium hyaluronate on adhesion prevention after flexor tendon surgery. METHODS: In 47 cases with the flexor tendon surgery, two kinds of sodium hyaluronate jelly preparations were injected into the tendon sheath before suture. Preparation I (20 mg/2 ml) was for group A (17 patients) and preparation II (20 mg/2 ml) was for group B (16 patients). The control group (group C, 14 patients) were treated in the same way except injection of sodium hyaluronate. The functions of afflicted fingers including flexibility, pain and swelling were measured immediately, at the first, second and the third month after operation. RESULTS: All 47 patients were followed up 1 to 3 months. 64.71% patients in group A and 68.75% in group B showed significant improvement. There were significant difference compared with group C (P < 0.05). There were no significant adverse reactions were observed in all groups. CONCLUSION: Two sodium hyaluronate preparations have effects in adhesion prevention after flexor tendon surgery with safety and expedience.
