Comparative Study
Volumetric changes of iliac crest autografts used to reconstruct the anterior column in thoracolumbar fractures: a follow-up using CT scans.
Patients with a thoracolumbar injury had a reconstruction of the anterior column using an tricortical iliac crest autograft. The volume and the length of the autograft were measured after 9 and 21 months using computed tomography. ⋯ The results show that more than a third of the initial graft volume is absorbed during the consolidation process. The loss was greater, the larger the volume of the initial graft was. The efficiency, however, was not dependent on the initial graft size.

Comparative Study
Stage-specific sagittal spinopelvic alignment changes in osteoarthritis of the hip secondary to developmental hip dysplasia.
A retrospective, age- and sex-matched radiographic study. ⋯ Pelvic inclination tended to increase in pre/early-stage OA patients. In healthy subjects, aging is associated with reduction of lumbar lordotic angle and tendency for posterior inclination of the sacrum. With aging, patients with OA maintained the lumbar lordotic angle and did not develop a posterior sacral slope angle.

Case report. ⋯ The early fusion prevented the customary severe progression of this condition and early death due to cor pulmonale. He is a fully functioning member of society. Will more modern treatments with lengthening of the hemithorax provide a better outcome? Only time will tell.

Survey. ⋯ Routine sedation does not seem to be required for patients receiving spinal injections, but more-anxious patients benefit from sedation before an injection. Benzodiazepams are effective in controlling anxiety for the majority of patients.

Randomized Controlled Trial
A prospective, randomized, double-blind study of the efficacy of postoperative continuous local anesthetic infusion at the iliac crest bone graft site after posterior spinal arthrodesis: a minimum of 4-year follow-up.
Parallel design, prospective, double-blinded, randomized, controlled trial composed of 2 independent groups treated with a continuous infusion catheter (saline vs. Marcain) placed into the iliac crest bone graft site (ICBG). ⋯ Continuous infusion of 0.5% Marcain at the ICBG harvest site significantly reduced chronic dysesthesias. Overall satisfaction with the procedure, number of painful days per month, and VAS scores were significantly better in the treatment group at 4 years. No long-term complications were attributed to either the ICBG site or the catheter-infusion system. The use of continuous local anesthetic infusion at the iliac crest may help in alleviating graft-related pain beyond the perioperative phase.
