- Discussion:
- in forearm, attention is directed to interval between tendons of
ECRL &
Brachioradialis, which is optimal site of insertion for proximal half pin;
- superficial branch of radial nerve emerges in interval between ECRL
brachioradialis mentioned tendons & should be identified & protected
when inserting the proximal Schanz screw;
- muscle bellies of
abductor pollicis longus &
EPB must be spared;
- it may be necessary to
position one Schanz screw proximal & second
distal to muscles;
- due to the divergence of the tendons of
ECRL &
ECRB in distal
forearm, optimal placement of distal Schanz screw is in interval
between them;
- border of this muscle group may be palpated between approx 4-5 cm &
4-10 cm proximal to the tip of radial styloid process;
- inadvertent transfixation of these muscles causes significant pain & greatly
impairs active and passive flexion and opposition of thumb;
