The aim of our study was to assess the outcome of caudal epidural injection for patients with low back pain in relation to fatty infiltration of spinal muscle. This is a prospective study. The spinal muscles were graded on sagittal section T1 MRI at the lower border of lumber 4 vertebra from 3 to 12 depending on the severity of fatty infiltration. The outcome of the intervention was assessed by improvement in pre and post intervention oswestry disability index score as well as visual analog pain score. Patients with significant fatty changes don't respond well to the caudal epidural injection.
In revision hip surgery, Type IIIB femurs have presented the greatest historical challenge to achieving stable fixation and osseous integration. This study evaluated the intermediate term outcome of a modular, tapered, distal fixation revision femoral component used in a consecutive revision hip series with special attention to its performance in the defective Type IIIB femur. Between February 2002 and January 2005, 51 consecutive revision hip arthroplasties were performed using modular, tapered, distal fixation femoral components. The femoral defects at the time of revision surgery were classified using a system previously described by Paprosky. The most recent radiographs were reviewed and clinic notes examined to assess femoral component stability.Purpose
