Abstract
Through the paediatric LCP Hip plating system (Synthes GmBH Eimattstrasse 3 CH- 4436 Oberdorff), the highly successful technique of the locking compression plate used in adult surgery, has been incorporated in a system dedicated to pediatrics. We are presenting the outcome of the paediatric LCP hip plating system used for a variety of indications in our institution.
We retrospectively reviewed the notes and radiographs of all those children who have had Paediatric LCP Plate for the fixation of proximal femoral osteotomy and proximal femur fractures in our institution, between October 2007 and July 2010, for their clinical progress, mobilization status, radiological healing and any complications.
Forty-three Paediatric LCP hip plates were used in forty patients (24 males and 13 females) for the fixation of proximal femoral osteotomies (n=40) and proximal femur fractures (n=3). The osteotomies were performed for a variety of indications including Perthes disease, developmental dysplasia of hip, Cerebral Palsy, Down's syndrome, coxa vara, Leg length discrepancy and previous failed treatment of Slipped Upper Femoral Epiphysis.
Twenty-five children were allowed touch to full weight bearing post operatively. Two were kept non-weight bearing for 6 weeks. The remaining 13 children were treated in hip spica due to simultaneous pelvic osteotomy or multilevel surgery for cerebral palsy.
All osteotomies and fractures radiologically healed within 6 months (majority [n=40] within 3 months). There was no statistically significant difference (p= 0.45) in the neck shaft angle between the immediately postoperative and final x-rays after completion of bone healing.
Among the children treated without hip spica, 1 child suffered a periprosthetic fracture. Of the children treated in hip spica, 2 had pressure sores, 3 had osteoporotic distal femur fractures and 2 had posterior subluxations requiring further intervention.
There were no implant related complications.
The Paediatric LCP Hip Plate provides a stable and reliable fixation of the proximal femoral osteotomy performed for a variety of paediatric orthopaedic conditions.
