title: Reconstruction of Mason type-III and type-IV radial head fractures with a new fixation device: 23 patients followed 1-4 years.
abstract: BACKGROUND
  Treatment options in radial head fractures of Mason types III and IV range from open reduction and internal fixation (ORIF) to radial head resection with or without prosthetic replacement.
  
  
  METHODS
  In a prospective study, the radiographic and clinical outcome was evaluated in 23 patients (age median 51 years) with 23 complex radial head fractures median 2 (1-4) years after ORIF using a new fixation device (FFS; Orthofix). 14 Mason type-III fractures with 2 concomitant olecranon fractures and 1 ulnar nerve lesion, and 11 type-IV fractures with 2 olecranon fractures and 2 fractures of the coronoid process were treated. 2 patients were lost to follow-up. In 7 cases of joint instability, an elbow fixator with motion capacity was applied after ORIF of the radial head.
  
  
  RESULTS
  No radial head resection was necessary. No secondary dislocations or nonunion occurred. The Morrey elbow score was excellent in 8 and good in 4 Mason type-III fractures and excellent in 5, good in 3, and fair in 3 Mason type-IV fractures.
  
  
  CONCLUSIONS
  Reconstruction of comminuted radial head fractures can be performed with this device and radial head resection can be avoided.
