Summary

Centralization surgery for radius dysplasia improves appearance but long-term hand function remains significantly impaired. Upper-extremity disability is mild, with no correlation between improved alignment and better function.

Area of Science:

  • Orthopedic surgery
  • Pediatric orthopedics
  • Reconstructive surgery

Background:

  • Radius dysplasia is a congenital condition affecting forearm development.
  • Centralization surgery aims to improve appearance, forearm length, and function.
  • Objective long-term outcome data for centralization are limited.

Purpose of the Study:

  • To evaluate long-term functional outcomes after centralization surgery for radius dysplasia.
  • To assess hand function and upper-extremity disability using standardized tests.

Main Methods:

  • A long-term follow-up study of 21 patients (25 wrists) an average of 20 years post-surgery.
  • Utilized the Jebsen-Taylor hand test to measure hand function.
  • Employed the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire for upper-extremity function assessment.

Main Results:

  • Jebsen-Taylor hand test scores were significantly impaired (average 48 seconds vs. normal 30 seconds, a 62% increase).
  • DASH questionnaire indicated mild upper-extremity disability (average 18%).
  • No correlation was found between improved wrist alignment/ulna length and better upper-extremity function.

Conclusions:

  • Centralization surgery results in markedly abnormal long-term hand function despite mild upper-extremity disability.
  • Surgical correction does not guarantee normal hand function in radius dysplasia patients.
  • Further research is needed to optimize functional outcomes in radius dysplasia treatment.
