Femoral neck osteosynthesis using interfragmentary compression or position screw in synthetic bones. What are the mechanical differences?

Purpose: We aim to compare interfragmentary compression with the position osteosynthesis in the fixation of different femoral neck fractures (FN) in synthetic bones subjected to vertical load.

Methods: Forty-two synthetic femurs were subjected to neck fractures and separated into 3 groups according to the Pauwels classification: Pauwels I had 6 units (PI); Pauwels II, 24 units, with and without comminution (PII); and Pauwels III, 12 units, with and without comminution (PIII). After, they were fixed with 2 different ways: three 7, 0 mm cannulated lag screws (CSs) versus three 6, 5 mm solid fully threaded screws (SSs).

[Occlusion of peripheral bypass--changing of an institutional paradigm].

Objectives: Compare the results of surgical thrombectomy (ST) and catheter directed thrombolysis (CDT) in the treatment of acute ischemia due to peripheral prosthetic bypass occlusion.

Methods: Retrospective single center analysis of the electronic clinical data on two groups of patients with acute lower limb ischemia due to prosthetic bypass occlusion: in one ST was performed (data collected between June-2006 ahd September-2011) and the other was treated with CDT Qui2 test (categorical variables) and independent samples t test (continuous variables) were used for comparisons between groups. The Kaplan-Meier method was used to estimate rates of freedom from reintervention and limb salvage, with the Log Rank test used for comparisons.

[Restenosis and Progression of Contra-Lateral Disease after Carotid Endarterectomy. A prospective study].

Objectives: Estimate the frequency and risk factors of restenosis after carotid endarterectomy, contralateral carotid disease development, neurologic symptoms (ipsi or contralateral) and new endarterectomy (ipsi or contralateral) in patients who underwent previously endarterectomy.

Methods: Retrospective single center analysis of the electronic clinical data and of duplex ultrasound results of 293 consecutive patients who underwent carotid endarterectomy between 2002 and 2008. The study included risk factors, procedure and patient's characteristics.

[Primary Aorto-enteric Fistula Related to an Aortic Pseudo Aneurysm].

Unlabelled: Primary aorto-enteric fistula is a very rare entity, with a high mortality. Direct aortic reconstruction is the preferred treatment, with extra-anatomic revascularization regarded as an alternative. Despite somehow promising results, the role of endovascular exclusion is still under scrutiny.
