The palmaris longus is the slender central wrist flexor whose tendon is the most commonly harvested tendon graft in hand surgery, used for zone II flexor tendon reconstruction, MPFL reconstruction, UCL repair, and many other procedures. It is absent in 14% (bilateral absence in 7%), tested by the Schaeffer test (opposing thumb and little finger with wrist slightly flexed — the PL tendon bowstrings visibly). The Z-lengthening harvest technique through two small incisions preserves the palmar fascia while obtaining a 14-16 cm graft.

Palmaris longus tendon harvest for graft requires confirming its presence by the Schaeffer or Pushpakumar tests before planning reconstruction. It is harvested through a small wrist incision, stripping from the muscle belly proximally. The PL is absent more commonly on the right side. The PL has no significant loss of function when harvested — patients report no deficit.
