Growth Modulation in Renal Osteodystrophy
Abstract
BackgroundRenal osteodystrophy causes progressive mechanical axis deviation, most often genu valgum, of the lower limbs. Guided growth is a useful procedure for the correction of angular deformities in children. Temporary partial closure of the physis (hemiepiphysiodesis) is a good therapeutic option. The aim of this study was to show the outcome and complications of this surgical procedure in pathological physes.MethodsWe present 11 patients (20 knees) diagnosed with chronic renal insufficiency and genu valgum who underwent temporary hemiepiphysiodesis at our Department. Eight-plates were placed in four patients and stapling was performed in the remaining seven. Pre and post-operative mechanical axis was evaluated on radiographs and the complications associated with each implant were assessed.ResultsComplete correction was obtained in four patients, one of whom suffered from recurrence of the deformity, and the remaining patients improved without achieving full normalization of the mechanical axis.ConclusionsThe correction achieved was clearly related to restore of kidney function. Patients who underwent kidney transplantation achieved adequate catch-up bone growth. No differences were found in outcome or complications between the two implants used.Downloads
