Superior Mesenteric Artery Syndrome as a Complication of Scoliosis Surgery.

Superior mesenteric artery (SMA) syndrome is a rare and potentially life-threatening complication of scoliosis surgery. The anatomical relationship of the duodenum and the superior mesenteric artery, the correction of angular deformity of the spine, and the normal adolescent growth spurt all contribute to the condition. We report the case of a 14-year-old boy who had a history of idiopathic scoliosis and presented with bilious vomiting that had persisted for 7 days after posterior T9-L4 fusion with instrumentation.

Arthroscopic insertion of a biologic rotator cuff tissue augmentation after rotator cuff repair.

Tissue augmentation has been used to reinforce repairs of massive chronic rotator cuff tears. This report describes a new technique for arthroscopic insertion of a biologic rotator cuff tissue augmentation. Double-loaded suture anchors are needed for the technique.
