The disease comprises 2.5% of all bone tumors and 7.5% of all benign bone neoplasm. It is the progressive, slowly developing disease and the optimum treatment remains unclear in many cases. <b>Aim: </b>In this study, the authors report their experience in the surgical treatment of four cases of craniofacial fibrous dysplasia. <b>Cases presentation:</b> The study involved 4 patients with craniofacial fibrous dysplasia. There were 3 men and a woman. The patients were 10, 17, 20 and 8 years old. No patient had a focal neurological deficit. The CT scan appearance was compatible with Fibrous dysplasia in all patients. The site of disease was frontal in one case and parietal in the other 3 cases. Cosmetic surgical treatment was performed in all patients. Cranioplasty was performed in one patient and planned for the other three. <b>Conclusion:</b> Fibrous Dysplasia is a benign slow growing disease that may cause as well as clinical symptom and aesthetical discomfort.

The purposes of this study were to evaluate the long-term outcomes and complications after surgery. Methods: We performed a retrospective match-controlled study in which 158 patients had 181 hips with developmental dysplasia of the hip. Radiographs were found of acetabular index, height of dislocation, Tönnis grade, abduction angle in the spica cast, and Severin grade. At final follow-up, deformity of femoral head or neck or acetabulum was evaluated according to the Severin. Avascular necrosis was rated according to Kalamchi. Clinical evaluation was made according to modified McKay criteria. Results: Between 2009 and 2012, 133 girls (84.2%) and 25 boys (15.8%) with developmental dysplasia of the hip underwent open reduction and ZOFA;135 (85.4%) were unilateral, and 23 (14.6%) were bilateral. Patients were divided into 2 groups: group 1 included 54 patients (62 hips) aged 12 months - ≤18 months and group 2 included 84 patients (119 hips), aged >18 months - ≤36 months. According to Tönnis system: type 3 appeared in 127 hips (70.2%), and Type 4 in 54 hip (29.8%). The anterior approach was used to expose inner table of the ilium and ZOFA in all cases. Acetabular index was improved;preoperation was 42.95°, and latest follow-up 17.26°. The Kirschner Wires (KW) were not used to fix the fibular allograft at the pelvic osteotomy site. All of the fibular allografts were completely incorporated in mean time of 14 weeks (range, 12 weeks - 17 weeks) post-surgery. Clinical evaluation according to modified McKay criteria: satisfactory result (excellent and good) was achieved in 141 hips (77.9%). Avascular Necrosis (AVN) happened in 61 hips (33.7%), redislocation in 18 hips (9.9%), coxa vara in 4 hips (2.2%), trendelenburg gait in 4 hips (2.2%), and supracondylar femoral fractures in 2 hips (1.1%). Conclusions: On the basis of this study, ZOFA was strength and graft 展开更多
