Correction and arthrodesis for cervical kyphosis associated with atetoid cerebral palsy has been considered to be difficult because of their involuntary neck movements and severe deformity. The aim of this study is to evaluate the surgical outcome of midline T-saw laminoplasty and posterior arthrodesis using pedicle screws. 15 patients were retrospectively reviewed. There were 6 women and 9 men, with a mean age 52.9 years (range 31–71 years). Mean follow-up period was 43 months (range 24–84 months). For clinical evaluation, the Japanese Orthopaedic Association (JOA) score and Barthel index (BI) which shows independence in ADL were used. For radiographic evaluation, change of C2–C7 Cobb angle of sagittal alignment, adjacent segment instability after the surgery were evaluated.Introduction
Methods
We report two new radiographic projections for evaluating avulsion fractures at the lateral malleolus. We used seven freshly amputated legs with simulated avulsion fractures and radiopaque markers to assess their value. The projections allow accurate assessment of the displacement of fragments without superimposition, and also show whether they affect the anterior talofibular or the calcaneofibular ligament or both.
