Radial Longitudinal Deficiency Classification / Treatment

  • Bayne I
    -delayed appearance of distal epiphysis and shortened radius
    -Treatment: stretching exercises, serial casting of splinting beginning shortly after birth.
  • Bayne II
    -deficient proximal and distal radial growth, very short radius
    -Treatment: stretching exercises, serial casting of splinting beginning shortly after birth. Consider progressive distraction lengthening (Sabharwal S, JPO 2005;25:377).
  • Bayne III
    -parital absence of the radius, geenerally distal
    -Treatment: centralization of the carpus done at 6-12 months of age. Consider index finger pollicization for patients with thumb hypoplasia (Goldfarb CA, J Hand Surg 2002;27A:118).
  • Bayne IV
    -radius completely absent
    -Treatment: centralization of the carpus done at 6-12 months of age. Consider index finger pollicization for patients with thumb hypoplasia (Goldfarb CA, J Hand Surg 2002;27A:118).

Radial Longitudinal Deficiency Associated Injuries / Differential Diagnosis

  • Thrombocytopenia-absent-radius
