<prompt> Thurston Holland sign is seen in ?Type IType IIType IIIType IV  <response>: Ans. is b i.e., Type II Epiphyseal Physeall Injuries o The junction between the metaphysis and epiphysis, i.e. physeal plategrowth plate, is the weakest point of a long bone in children and is, therefore, most vulnerable to shearing forces. o Salter and Harris have classified epiphyseal injuries into five types ? Type I : Complete separation of epiphysis from the metaphysis without fracture. Common in rickets, scurvy and osteomyelitis. Type II: The fracture involves the physis and a triangle of metaphyseal bone Thurston Holland sign.This is the commonest type of epiphyseal injury accounting for 73 percent of cases over 10 years of age. Type III: The fracture is intra- aicular and extends along the physis and then along the growth plate. This injury is relatively uncommon. Type IV: The fracture is intra- aicular and extends through the epiphysis, physis and metaphysis. Perfect reduction is necessary and open reduction is more often necessary to prevent growth arrest. Type V : Crushing of epiphysis. Growth arrest usually follows. Type VI Rangs type : There is a peripheral physis perichondrial ring injury.
