A simplified technique to correct hyperextension deformity of the metacarpophalangeal joint of the thumb
I Kessler
A flexible hyperextension deformity of the metacarpophalangeal joint of the
thumb in eleven patients was repaired by tendon reinforcement of the volar
capsule of the joint using the tendon of the extensor pollicis brevis. This
tendon, which was regarded as a deforming factor, was left attached at its
insertion on the proximal phalanx and was divided at the musculotendinous
junction proximally. The mobilized tendon was pulled out distally and then
passed proximally and volarly, first superficial to the sheath of the long
flexor tendon and then back through a hole in the neck of the metacarpal,
and finally in a distal direction to form a criss-cross pattern and be
sutured to the tendon of the adductor pollicis. The procedure gave reliable
results after an average follow-up of 6.5 years in these eleven patients
who had rheumatoid, paralytic, and traumatic lesions.
