Özet

Purpose: Obstetrical palsy of the upper extremity repre-

sents a severe traumatic complication, which involves the


brachial plexus and occasionally the osteoarticular struc-

tures and muscles of the shoulder. Our aim is to describe


and find an adequate modality of treatment for the rela-

tively frequent obstetrical palsy sequela presented as fore-

arm supination deformity. Forearm supination deformity


tends to be progressive and therefore early recognition of

this deformity is of paramount importance to prevent fixed

deformities, which increase the hand function deficit.

Forearm supination deformity is classified in two stages:

flexible (posture in supination) and fixed (contracture)


deformity, which directly determine the choice of the oper-

ative procedure(s). When passive reduction of the supina-

tion deformity is possible (flexible deformity) soft tissue


procedures including tendon transfers are indicated. The

bony procedures should be preferred in cases with severe


contracture of the forearm in supination and distal radio-

ulnar joint luxation (fixed deformity). In this study we used


soft tissue techniques (including biceps re-routing

pronotoplasty, brachioradialis re-routing pronotoplasty


with or without interosseous membrane release) and tech-

niques which include osteotomy of the forearm bones (ex-

cision of the radial head, radius pronation osteotomy, distal


radio-ulnar fusion and wrist arthrodesis) to restore fore-

arm posture and wrist stability in patients with supination


deformity secondary to brachial plexus birth palsy.

Methods: Forty-three children (27 male, 16 female) whose


age ranged between 3 and 15 years (mean age 8.2) oper-

ated between 1998 and 2004 were included in this study.


Eighteen of them (11 male, 7 female) underwent soft tissue

procedures, while twenty-five (16 male, 9 female) had

osteotomy.


Results: As soft tissue procedures, the selected tech-

niques were biceps re-routing pronotoplasty for 4 children and brachioradialis re-routing pronotoplasty for 14 of

them. Average gain in active pronation was 82.5 degrees,

average loss of active supination was 22.5 degrees and

average gain in total active motion was 55 degrees for

the biceps re-routing group, whereas average gain in

active pronation was 63.5 degrees, average loss of active

supination was 11 degrees and average gain in total active

motion was 53.2 degrees in brachioradialis re-routing

group. Selected techniques were excision of the radial

head for 4 patients, radius pronation osteotomy for 6

patients, distal radio-ulnar fusion for 4 patients and wrist

arthrodesis for 4 patients as the osteotomy procedures.

Average gain in active pronation was 96 degrees in radius

head excision, 66 degrees in radius pronation osteotomy,

61 degrees in distal radio-ulnar fusion and 58 degrees in

wrist arthrodesis groups. For the osteotomy group as a

whole, the mean active forearm supination decreased


from 50.4 degrees preoperatively to 40.8 degrees after sur-

gery. More than one procedure (mostly 2-3) were often


necessary to achive the desired results.

Conclusions: These results clearly show that patients can

benefit from surgical correction of forearm supination


deformity which probably will cause significant improve-

ment in functional status. After these surgical procedures,


in a considerable proportion of patients, the "begging hand"

posture can be corrected to a more functional and less

noticeable position. Key words: Obstetric palsy, brachial

plexus, supination deformity, osteotomy, brachioradialis

re-routing pronotoplasty.
