Dislocation of fingers
Dislocation means slipping of the joint from its normal position. A finger has three joints ; MCP joint, PIP joint and DIP joint.
Finger dislocations can occur at three levels
- MCP joint ( Known as Kaplan’s dislocations )
- PIP joint
- DIP joint
Your doctor may ask for a plain X ray to confirm the diagnosis. Rarely CT may be required to obtain detailed information especially in fracture dislocations.
Most of such injuries are managed successfully without surgery. They often are reduced in the outpatient clinic under local anaesthesia and splinted.
They may be simple or complex. Simple dislocations are managed in the outpatient clinic by bringing the joint to its normal position after giving local anaesthetic . Complex dislocations are often irreducible. Trial of reduction with local anaesthetic is attempted in an outpatient clinic. If successfully reduced , the finger is immobilised using a splint. If the trial is not successful , surgery will be required to bring the joint back to its normal position.
They are common injuries. They may be stable or unstable.
Stable ones are reduced under local anaesthetic in the outpatient clinic and splint
is applied.
Unstable ones need surgery.
Surgeries performed are
- Extension block pinning
- Dynamic skeletal traction Eg. Suzuki frame, Zimmer splint etc
- Open reduction and screw/ plate fixation
- Volar plate arthroplasty
- Hemihamate arthroplasty
