  • Title: Physeal arrest due to laser beam damage in a growing child.
    Author: Peterson HA, Wood MB.
    Journal: J Pediatr Orthop; 2001; 21(3):335-7. PubMed ID: 11371816.
    Abstract:
    A laser beam applied directly to epiphyseal cartilage may damage the cartilage selectively without affecting adjacent bone. The damaged physis is replaced by bone, which forms a bone bridge between the metaphysis and epiphysis, similar to the bone bridges that follow fracture of any long bone. This case report documents damage to two distal phalangeal epiphyseal plates as a sequela of laser beam injury. This resulted in premature partial physeal closure (physeal bars), which in turn caused progressive angular deformity and relative shortening of the digits, requiring multiple osteotomies for correction. This report suggests that special care must be exercised when using laser therapy near physes in growing children.
