- Discussion:
- potential space between
FPL tendon,
FDP tendons, &
pronator quadratus;
- is known as the subtendinous space of the wrist or Parona's space;
- pus in FPL sheath can ascend in the
radial bursa and eventually rupture into this space;
- pus in little finger sheath can ascend in
ulnar bursae & rupture into Paron's space;
- pus from
thenar abscess or
midpalmar abscess may rupture into Parona's space;
- if pus from either the
radial or
ulnar bursae ruptures into Parona's space, it can be drained
by the same incision used for releasing pus from the proximal end of the
ulnar bursae;
