Common hand and finger deformities
Terms in this set (10)
Spoon shaped nails are often the result of:
fungal infection, anemia, iron deficiency, long term diabetes, local injury, developmental abnormality, chemical irritants, or psoriasis
Clubbed nails may result from:
hypertrophy of the underlying soft tissue or respiratory or cardiac problems such as COPD, emphysema, congenital heart defects, or cor pulmonale
Wasting of the thenar eminence of the hand occurs as a result of a ______ nerve palsy. This is also know as ape hand.
Wasting of the hypothenar muscles of the hand, the interossei muscles and the two medial lumbricals occurs due to ______ nerve palsy. Known as Bishop's hand or Benediction hand deformity (ducchene's sign). Hyperextension of MTP and flexion of the IP joints.
This deformity involves extension of the MTP and DIP and flexion of the PIP. Common in RA.
This deformity involves MTP joints hyperextended, and PIP and DIP are flexed.
This deformity is seen with a malunion distal radial fracture (colles fx) with distal radial fragment angulated posteriorly.
dinner fork deformity
This results from a radial nerve palsy, and the wrist extensors are paralyzed, causing the wrist and fingers do disable the ability to actively extend.
This deformity is the result of a rupture or avulsion of the extensor tendon where it inserts into the distal phalanx of the finger. The distal phalanx rests in a flexed position.
This deformity usually only involves the fingers. There is flexion of the MTP and DOP joints, but the real deformity is extension of the PIP.
