A Case Series That Supports the Application of the S2AI Technique for Fractures and Failures After Lumbosacral Fusion.

Background: Sacral fractures and failures are uncommon after lumbosacral fusion but have received increasing attention in the surgical literature. They can be difficult to diagnose, making timely treatment difficult. No consensus has been reached on the characteristics of these complications or on optimal treatment.

Proximal periarticular locking plates in proximal humeral fractures: functional outcomes.

Background: Some recent studies have asserted that locking plates do not provide adequate fixation of proximal humeral fractures. The purpose of this study is to review our experience with proximal humeral locking plates, including complications, functional outcomes, and predictors of successful treatment.

Materials And Methods: At our institution, 45 patients (46 shoulders) with displaced proximal humeral fractures were treated with a proximal humeral locking plate over a 6-year period.

Change in sagittal balance with placement of an interspinous spacer.

Study Design: A prospective case series.

Objective: To determine the effect of X-STOP implantation on sagittal spinal balance using 36-inch films.

Summary Of Background Data: Interspinous process spacers have been shown as an effective treatment of neurogenic claudication.

The anatomic suitability of the C2 vertebra for intralaminar and pedicular fixation: a computed tomography study.

Background Context: Several methods have been used to stabilize the atlantoaxial joint, including the use of C2 pedicle and laminar screws. No report has used computed tomography (CT) angiograms to compare the risk to the vertebral artery or assess the suitability for each fixation technique.

Purpose: To compare the suitability of C2 pedicle versus laminar screws using CT angiograms.

An S-2 alar iliac pelvic fixation. Technical note.

Multiple techniques of pelvic fixation exist. Distal fixation to the pelvis is crucial for spinal deformity surgery. Fixation techniques such as transiliac bars, iliac bolts, and iliosacral screws are commonly used, but these techniques may require separate incisions for placement, leading to potential wound complications and increased dissection.
