My son (24 y/o, in otherwise good health) cut thru his left thumb extensor tendon at work and had the surgery to re-connect the parts a few days ago. The medical paperwork simply stated "Left Thumb Extensor Tendon". I gather there is more than one tendon in that area, but after the injury the primary movement axis affected was that he couldn't "thumbs-up" if that helps.
Nearest related thread I could find on here was:
extensor tendon, but it was almost a decade ago.
Post-surgery recommendations are: 2 weeks in a rigid cast with no movement, that cast replaced by a longer-term model at the meeting with the rehab specialist, and then 12 sessions of rehab over 4 to 6 months at which time restrictions should be lifted.
Any general recommendations he should be doing during the recovery period to try and make sure this heals properly? Might collagen supplements help?
Thanks.
