Multicenter Study Clinical Trial
Solitaire AB stent-assisted coiling of wide-necked intracranial aneurysms: mid-term results from the SOLARE Study.
Endovascular treatment of intracranial aneurysms can be technically difficult when the neck is wide. The Solitaire AB stent (Covidien, Irvine, California), the only fully retrieved stent, assists in the coiling of wide-neck intracranial aneurysms. ⋯ Stent-assisted coiling of wide-necked intracranial aneurysms was found to be safe and effective with the Solitaire AB stent at 6-month follow-up. Angiographic results improve with time due to progressive thrombosis of the aneurysm.

Comparative Study
Biomechanical assessment of anchored cervical interbody cages: comparison of 2-screw and 4-screw designs.
A new anchored cervical interbody polyetheretherketone spacer was devised that uses only 2 integrated variable-angle screws diagonally into the adjacent vertebral bodies instead of the established device that uses 4 diagonal fixed-angle screws. ⋯ The 2-screw variable-angle anchored cage significantly reduces ROM relative to the intact spine. Greater stability can be achieved, especially during extension and axial rotation, by using the 4-screw cage or standard plate plus cage.

The surgical treatment of spontaneous posterior interosseous nerve (PIN) palsy with hourglass-like fascicular constriction (HLFC) remains controversial. ⋯ Ultrasound is a helpful diagnostic technique for spontaneous PIN palsy with HLFC. Surgery is necessary for PIN constriction if conservative treatments fail. Surgical choices depend largely on the thinning extent of the PIN constriction and the age of the patients. The outcomes of patients aged ≥50 years were much worse. We suggest NY for mild to moderate, and neurorrhaphy or autografting for severe PIN constriction.
