Objective:
To explore the reasons of tendon adhesions post tendon allograft.
Methods:
From May 1990 to June 2000, 85 cases receiving tendon allograft were given tenolysis because of tendon adhesions. There were 76 males and 9 females, with an average age of 24.5 years (8-46 years). Injury was caused by machine in 38 cases, electric in 32 cases, cut in 4 cases, explosion in 4 cases and extremity mutilation in 7 cases; including 66 cases of flexor tendon deficit and 19 cases of extensor tendon deficit. Six cases had 1 tendon deficit, 79 cases had tendon deficit of more than 2. The defect region ranged from I to V. The total mobility of the joint was less than 220 degrees in 73 cases. The impairment of skin, bone, nerve and vascular were treated before tendon allograft.
Results:
Because TAM was less than 50% of TPM, the patients were given tenolysis 4-15 months after operation. And the mobilization began at the first day after operation to improve the range of active movement. Patients were followed up 7-17 years (mean 12.7 years). TAM and TPM were in accord. Mean total mobility of joint was 200 degrees.
Conclusion:
The serious of primary hurt is the important factors of tendon adhesion. Improvement of tendon selected, treatment and early mobilization can relieve the tendon adhesion.
