“Nothing will work unless you do.”

Maya Angelou, born Marguerite Annie Johnson; (1928 – 2014), American memoirist, poet, and civil rights activist.

Since a long time, practitioners observe serious thumb laxity after a sprain.

Immobilization applied left still a few of those without healing.

B. Stener, a Swedish orthopedic surgeon described in 1962 an interposition of the adductor pollicis aponeurosis in the gaping rupture of the metacarpo-phalangeal ulnar collateral ligament of the thumb.

It became generalized practice to order Ultrasound or MRI to identify this particularity.

Results in publications remain conflicting nowadays reporting a frequency from 18 up to 88%.

This high ratio (almost 90%) is in contradistinction to successful healing on immobilization of most cases!

To my astonishment no one discusses position in the cast. What if attention is paid to placing the thumb adducted in the plaster? (The adductor pollicis aponeurosis relaxed)
