Finger Disclocations: Type and Diagnosis
- PIP joint dislocations (coach’s finger) can be very
- The injury can involve the static (collateral ligaments and
volar plate) stabilizers and the dynamic (intrinsic muscles,
central slip and lateral bands) stabilizers.
- Digital arteries and nerves may also be involved.
- The dislocation can be dorsal, volar or lateral.
- Most PIP joint dislocations are dorsal, which can result in
swan neck deformities if untreated.
- Volar dislocations when untreated can result in a
boutonniere or pseudo- boutonniere deformity.
- A true boutonniere deformity has a disruption of the
central slip, not the volar plate.
- Diagnosis can be made with plain X-rays and need to be
performed to rule out fractures.
- An evaluation should also rule out tendon avulsions such
as mallet finger or FDP disruption.
Our Occupational Therapists are the go-to for finger dislocations. Occupational Therapy is available at our Bedford and Nashua offices.
