title: Hemi-hamate arthroplasty for pilon fractures of finger.
abstract: BACKGROUND
  Injury following proximal interphalangeal joint fracture dislocation is determined by the direction of force transmission and the position of the joint at the time of impact. Dorsal dislocations with palmar lip fractures are the most frequently encountered. The degree of stability is directly determined by the amount of middle phalangeal palmar lip involvement.
  
  
  METHODS
  Hemihamate arthroplasty procedure was used in the reconstruction in five cases with comminuted, impacted fractures of the proximal end of middle phalanx of the finger. Three patients were presented within 2 weeks; one patient came by one month and the other by three months following the injury. All patients presented with posterior subluxation of PIP joint.
  
  
  RESULTS
  Functional outcome following this procedure in both acute and chronic cases resulted in adequate restoration of joint stability and function.
  
  
  CONCLUSIONS
  Hemihamate arthroplasty is an adjuvant in the treatment of unstable intra-articular pilon fracture involving PIP joint.
