This report is being filed after the review of the following journal article: becker, c.E., keeler, k.A., kruse, r.W., shah, s.A.(1999), complications of blade plate removal, journal of pediatric orthopaedics, vol.19 (2), pages 188-193 (usa).The aim of this retrospective study is to show that removal of the blade plate was a relatively safe procedure in those patients troubled by prominent/painful hardware or skin breakdown.Between january 1990 to june 1997, a total of 229 children (121 boys and 108 girls) had removal of one or two blade plates, with a total of 244 procedures and 426 blade plates removed.The ao fixed-angle blade plate (synthes, paoli, pa, u.S.A.) has been used in children for fixation of proximal femoral osteotomy.The average follow-up was 31 months (range: i-93 months).The average age at the time of the initial procedure was 9 years 5 months (range: 2-19 years 10 months).The mean time to blade-plate removal was 17 months (range: 2-74 months).The average age at blade-plate removal was l0 years l0 month (range: 2 years 11 months-20 years 11 months).The following complications were reported as follows: patient 1 had a proximal femur fracture right side which occurred at the time of plate removal.Patient 2 had a proximal femur fracture left side occurred 1 day after the child¿s bilateral plate removal.Patient 3 had a femoral neck fracture left side occurred 12 weeks after his blade plate was removed, which was thought that the seizure caused his left femoral neck to fracture through a portion that may have been weakened by the recent blade-plate removal.The indications for blade-plate removal were prominent/painful hardware in 74%, skin breakdown/infection in 13%, and unspecified in 13 percent.This report captures the reported events of prominent/painful hardware in 74 percent, skin breakdown/infection in 13 percent, unspecified in 13 percent.This report is for an unknown synthes plates.This is report 7 of 8 for (b)(4).
