Clinical evaluation of cervical interspinous fusion under local anesthesia in elderly patients with cervical spondylotic myelopathy. ⋯ Twelve high-risk patients with cervical spondylotic myelopathy were treated with posterior interspinous fusion using wave-shaped rods inserted under local anesthesia. This method was evaluated as an effective surgical salvage without any mortal complications even in the elderly high-risk patients.

Two cases of spondylolisthesis due to severe elongation of pedicles in osteogenesis imperfecta are reported. ⋯ High-grade spondylolisthesis due to elongation of pedicle in osteogenesis imperfecta is uncommon. Anterior interbody fusion of all the involved motion segments has produced good pain relief and arrested deformity progression at the 3-year follow-up.

Description of surgical technique with case correlation. ⋯ In properly selected patients an anterior revision approach can provide a better outcome than posterior cervical fusion. This modified approach allows placement of an adequate fixation screw in a vertebra damaged by previous screw failure.

A retrospective review of 51 patients with adolescent idiopathic scoliosis (AIS) treated with a Boston brace for curves ranging from 36 degrees to 45 degrees. ⋯ Patients with a double curve pattern in which the thoracic curve is >35 degrees and the LPR angle is >12 degrees are significantly more likely to demonstrate curve progression. In-brace correction for double curves of at least 25% and a patient's ability to wear the orthosis >18 hours/day significantly increased the likelihood of success.
