A 10-year-old male patient with Legg–Calve–Perthes disease of the left hip presented with progressive pain in the left hip of 6 months duration. The pain was exacerbated by daily life activity. Physical examination showed positive antalgic gait. Range of motion of the hip joint was limited, particularly flexion, abduction, and internal rotation. Plain radiographs showed lateral pillar type C.\nHe had an external fixator for 3 months. His Hip pain was improved from 7 to 1 point on the NRS at the final follow up. Moreover, the involved hip joint’s range of motion in flexion, internal rotation, and abduction was also improved compared with the preoperative values. On the radiological evaluation, the sphericity deviation score, epiphyseal index, and the cervical index were all improved at the final follow up (-).
A 10-year-old- child with left hip Legg–Calve–Perthes disease. He presented with pain in the left hip of 2 months duration. It was increasing progressively that badly affected his daily life activities. Oral analgesics improved the pain temporarily. He showed antalgic gait on physical examination. In addition to that, limited hip motion, particularly flexion, abduction, and internal rotation. Pelvis X-ray showed lateral pillar type C. The patient underwent same index procedure. His external device was removed after 2.5 months of application. He followed the same postoperative protocol. Two months postoperatively, the patient developed pin tract infection involving mainly the supraacetabular screw group. He was managed with empirical oral antibiotics but did not respond well. A decision was made to remove the fixator and to debride the wound tracts and to keep him on intravenous antibiotics. Five days after fixator removal, he showed clinical improvement and discharged. Postoperative protocol was followed then smoothly. All physical and radiological parameters had been improved at the final follow up. (-)
