Evaluación del seguimiento radiográfico para desplazamiento de cadera en pacientes con parálisis cerebral en el Centro Hospitalario Pereira Rossell

Introduction: hip luxation is a severe complication in patients with cerebral palsy (CP), especially in gross motor functional classification system (GMFCS) III-V patients. Pelvic x-rays are necessary to identify this condition.Objectives: to assess the x-ray follow-up in these patients and the early detection of this complication in  our hospital. Method: the medical records and x-rays of 17 GMFCS III-V patients who were between 2 and 8 years old at the time of index pelvic x-ray were reviewed, measurement of the hip migration percentage according to Reimer´s index, the cervical-diaphyseal angle and calculation of the CPUP hip score for each hip. We assessed the follow-up x-ray a year later or later than that date, and in the even this had not happened, we would call the patients in for a control x-ray to identify the hips with an increase migration risk.Results: 3 (18%) out of 17 patients assessed underwent a new pelvic x-ray a year later. 6 patients (35%) underwent one later than one year after and prior to the control visit planned, 7 (41%) patients were never controlled and they were called for a new x-ray in 2018. One patient (6%) was lost during follow-up. One patient had an increased risk hip (CPUP Score 50-60%), the rest had normal migration percentages.Conclusions: few patients with PC GMFCS III-V underwent annual follow-up. Those monitored did not evidence progression of this condition. This study and the relevant literature back up the introduction of a surveillance program in our hospital.
