Hh. Lin et al., A SURGICAL TECHNIQUE OF RADIOULNAR OSTEOCLASIS TO CORRECT SEVERE FOREARM ROTATION DEFORMITIES, Journal of pediatric orthopedics, 15(1), 1995, pp. 53-58
Twenty-six forearms in 23 patients with marked pronation or supination
deformities were treated with osteoclasis. Etiologies included 12 rad
ioulnar synostoses, five brachial plexus injuries, three hemiplegias,
two hemimelias, and four other types of deformities. Drill-assisted os
teotomy of both the radius and ulna was followed 10 days later by mani
pulation to the desired functional position. Dominant extremities were
placed in 20 degrees pronation, and nondominant extremities in 20 deg
rees supination. Range of motion was not significantly changed, but th
e are of motion occurred in a more functional hand position. Average c
orrection for 15 pronation deformities was 81 degrees and 69 degrees f
or 11 supination deformities. Two nonunions healed after bone grafting
and there were no instances of neuromuscular compromise. Functional i
mprovement was obtained in 25 of 26 forearms.
