Comparative Study Clinical Trial
Continuous decompression of unicameral bone cyst with cannulated screws: a comparative study.
We determined the role of mechanical decompression in the resolution of unicameral bone cyst. A total of 69 children with unicameral bone cysts were treated either by (i) open curettage and bone grafting, (ii) steroid injection or (iii) cannulated screw insertion. ⋯ The healing rates in the three groups were 25, 12 and 29% after the first treatment, and a further 50, 19 and 65% after the second. The study has demonstrated the advantages of the decompression technique for unicameral bone cysts over other treatment modalities studied.

We carried out a retrospective analysis to investigate the prevalence of superior mesentery artery syndrome (SMAS) in children who underwent scoliosis surgical repair at our hospital between 1998 and 2006 and to reassess the syndrome's pathogenesis. Among 133 consecutive pediatric patients, two cases were identified, both 13-year-old girls with idiopathic scoliosis, undergoing surgery using third-generation instrumentation systems. ⋯ SMAS might occur after derotation and translation forces application, and even with nonextreme corrections. Low BMI and significant weight loss at presentation are not mandatory.
