Abstract
Introduction
Coxa vara is an uncommon orthopaedic condition. Problems associated with the definition, radiological appearance, classification and surgical treatment are discussed.
Methods
A clinical and radiological review of 11 patients (14 hips) treated with a LCP plate (Synthes) in our paediatric orthopaedic unit from 2010 to 2013 was performed. These hips were classified as congenital (6), developmental (3) and acquired (5).
The Hilgenreiner Epiphyseal (HE) angle, the head/shaft angle and the neck/shaft angle were all assessed and examples shown why one measurement does not address every case.
Results
A mean radiological improvement of 45 degrees (20–75 +/−16.5 degrees) was obtained. There was no loss of position in any of our patients from initial surgery until union. Complications included over-correction (1 case), under-correction (2 cases) and a peri-prosthetic fracture in a patient with Osteogenesis imperfecta.
Conclusions
Limitations of the LCP system include a demanding surgical technique and, in South Africa at least, a limited plate selection.
Advantages include excellent proximal control with precise correction, and in our experience provide the best fixation for valgizing proximal femoral osteotomies in the paediatric coxa vara patient.
