[Analysis of reasons of tendon adhesion post tendon allograft].
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.


CONCLUSIONS
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.
