Radio-ulnar synostosis, a congenital elbow defect, can cause severe disability. Derotational osteotomy is recommended for surgical correction to restore forearm function, with specific angle targets for each hand.

Area of Science:

  • Orthopedic Surgery
  • Congenital Malformations
  • Upper Extremity Reconstruction

Background:

  • Radio-ulnar synostosis is a congenital elbow joint malformation.
  • It can lead to significant functional impairment, particularly with bilateral involvement or hyperpronation.
  • Surgical intervention is indicated for fixed pronation of 60 degrees or more.

Purpose of the Study:

  • To evaluate derotational osteotomy as a surgical solution for radio-ulnar synostosis.
  • To establish optimal postoperative forearm positioning for functional restoration.
  • To outline a safe surgical approach for complex derotational procedures.

Main Methods:

  • Derotational osteotomy at the synostosis site.
  • Postoperative positioning recommendations: 15-35 degrees pronation for the dominant hand, 15-30 degrees supination for the contralateral hand.

  • Staged surgical approach for major derotational procedures to mitigate neurovascular risks.

    • Main Results:

    • Derotational osteotomy is presented as the preferred surgical method.
    • Specific functional forearm positioning goals are defined for improved outcomes.
    • Multi-stage surgery is advised to prevent complications.

    Conclusions:

    • Derotational osteotomy is the most effective procedure for correcting radio-ulnar synostosis.
    • Achieving specific postoperative forearm angles is crucial for functional recovery.
    • Staged surgical interventions are essential for managing severe cases and avoiding complications.
