PERIOSTEAL TETHER CAUSING ANGULAR GROWTH DEFORMITY - REPORT OF 2 CLINICAL CASES AND AN EXPERIMENTAL-MODEL

Two human cases of periosteal tethering causing a disturbance of longi tudinal bone growth are presented. Production of a periosteal tether i n an experimental rabbit model supported a causal relationship between the tether and the growth disturbance. Excision of the periosteal tet her (with or without an osteotomy) produced some correction of the gro wth disturbance in these two cases. One should keep this entity in min d as a possible cause for an acquired growth disturbance in a long bon e.
