Clinical and radiologic follow-up of patients with osteoporosis with painful, traumatic A3-type vertebral compression fractures in the thoracic and lumbar spine. ⋯ Balloon Kyphoplasty in combination with short-segment posterior instrumentation in traumatic A3 vertebral fractures led to a significant reduction in pain and disability. The combination of both surgical techniques was able to restore and maintain vertebral body height and correction of angular deformity. This technique might offer important safety advantages over an invasive anterior-posterior approach.

The use of locked plates in repairing osteopenic 3- and 4-part proximal humerus fractures remains controversial. The purpose of this article was to report the outcomes of open reduction and internal fixation in low-energy proximal humerus fractures treated with locked plating in patients older than 55 years and stratify risk of failure or complication based on initial radiographic features. ⋯ Neer 3- and 4-part proximal humeral fractures in older patients with initial varus angulation of the humeral head had a significantly worse clinical outcome and higher complication rate than similar fracture patterns with initial valgus angulation. Two factors had significant influence on final outcome in these fracture patterns: initial direction of the humeral head angulation and length of the intact metaphyseal segment attached to the articular fragment. The best clinical outcomes were obtained in valgus impacted fractures with a metaphyseal segment length of greater than 2 mm, and this was independent of Neer fracture type. Humeral head angulation had the greatest effect on final outcomes (P < 0.001), whereas metaphyseal segment length of less than 2 mm was predictive of developing avascular necrosis (P < 0.001).
