Background:
Cerebral palsy of the hand can be a seriously debilitating illness,
especially hand activities demanding the use of two hands can be affected. Being
able to extend the wrist allows for better visual apprehension, when manipulat-
ing objects. Increased tension of finger flexors permits improved grip strength.
Purpose / Aim of Study:
To evaluate the long-term effect of tendon trans-
fer with flexor carpi ulnaris (FCU) transferal to the extensor carpi radialis brevis
(ECRB)
Materials and Methods:
Twenty-five patients with cerebral p palsy was surgi-
cally reconstructed with f flexor carpi ulnaris (FCU) transferal to t the extensor
carpi radialis brevis ( (ECRB) and other surgery as needed, i including correc-
tion of thumb and p pronation. Age 15,3(9,8-29,2) years. Wrist extension was
classified using Zancolis classification of wrist and f finger deformity pre- post-
operatively. In a addition, DASH and grip strength, was a also measured pre-
postoperatively.
Findings / Results:
On follow up after 588 days (512-680) eleve eleven of
Twenty-five patient showed impro improvement in Zancolli classification. Anoth
Another 11 remained unchanged and 3 patie patients degraded one level.
Zancolli befor befor 2,4(0,3) (avg(sem)), on followup 1,6(0,2) (0,2) (p<0,05).
DASH was improved 10 points (-21-40). From From 57(3) to 47(3) (p< 0.01)
on followup. All but 3 patients showed improved grip str strength on average
2,9, from 5.4(1.4) to 8.2 8.2(1.6) (p< 0.01).
Conclusions:
In carefully selected adolescent children with cerebral palsy wrist
function and grip strength can be improved with tendon transfer with flexor
carpi ulnaris (FCU) transferal to the extensor carpi radialis brevis (ECRB). DASH
score shows improvement, although statistical significant, improvement of 10
point is not consider clinical relevant.
