ABSTRACT
Study Design: This was a retrospective comparative study. Objectives: The aim of this study was to perform a clinical and radiological retrospective evaluation of the most used techniques for the lumbar degenerative disk disease (DDD) treatment: arthrodesis versus dynamic neutralization (DN)-Dynesys dynamic stabilization system. Methods: The study included 58 consecutive patients affected by lumbar DDD, 28 treated with rigid stabilization and 30 with DN at our department between 2003 and 2013. The clinical evaluation was performed through the Visual Analog Scale (VAS) and the Oswestry Disability Index (ODI). The radiographic evaluation was performed through standard and dynamic X-ray projections and magnetic resonance imaging. Results: Both techniques determined a clinical improvement in the postoperative period compared to the preoperative one. There were no significant differences between the postoperative VAS of the two techniques. The DN group postoperative ODI percentage showed a significant improvement (P = 0.026) compared to the arthrodesis group. During the follow-up, no clinically significant differences were highlighted between the two techniques. At a long term follow up period, radiographic results showed, in both groups, a L3-L4 disk mean height reduction and an increase of segmental and lumbar lordosis without significant differences between the two techniques. During an average of 96-month follow-up period, 5 (18%) patients developed an adjacent segment disease in the arthrodesis group and 6 (20%) patients developed this syndrome in the DN group. Conclusions: We are confident in recommending arthrodesis and DN as effective techniques for lumbar DDD treatment. Both techniques are potentially burdened, with similar frequency, by the development of long-term adjacent segment disease.
ABSTRACT
Retrograde intramedullary fixation has been proposed to improve the rate of union providing greater stability in patients with a posterior cruciate ligament retaining femoral TKA component and decreasing soft-tissue trauma. This study assessed the clinical and radiographical outcome of retrograde intramedullary nailing (RIN) for the treatment of periprosthetic supracondylar fractures of the femur in an elderly population. Between January 2014 and December 2018, 16 patients with PSF underwent RIN. The clinical outcome was evaluated using the Knee Society Score (KSS) and the Short-form health survey (SF-12). The radiographic outcome was evaluated directly on the X-rays. Complications were also described. 13 patients (11 females and 2 males) with a mean age of 84 years old (range, 77-89) were evaluated clinically and radiographically, after a mean of 48.3 months (range, 24-73 months). The SF-12 scores were similar to normative values for subjects in the comparable age group. Radiographic union was obtained in all patients after an average of 14,8 weeks (range, 12-40 weeks) postoperatively. RIN is a safe and effective treatment for PSF, above all in the elderly population. The overall clinical and radiographic result was satisfactory.
ABSTRACT
Atrial septal aneurysm (ASA), common finding in normal echocardiographies, has been described in association with transient ischemic attacks (TIAs)/strokes, as well as hypertensive end-organ damage such as left ventricular (LV) hypertrophy. Aim of this study was to assess if a cluster of echocardiographic aspects could characterize TIA hypertensive patients. A cross-sectional study on patients with history of TIA, referring to a Hypertension Center echolab, has been performed. A total of 5223 patients received transthoracic echocardiography. TIA patients were 292 (5.6%). A total of 102 age/sex-matched patients without TIA have been collected as controls. The main characteristic of TIA patients resulted ASA/bulging (B) (TIA 61%, controls 6%, P = .0001). Other aspect was LV concentric remodeling (TIA 32.3%, controls 20.8%, P = .029) and mitral flow aspects of diastolic dysfunction. After adjustment for age and hypertension, ASA/B (odds ratio [OR] = 62.4, 95% confidence interval [CI]: 13.6-73.9, P < .001), followed by LV concentric hypertrophy (OR = 2.1, 95% CI: 1.1-4.3, P = .043), was associated with a positive TIA history. A binary logistic regression performed in ASA/B patients, identified relative wall thickness as the strongest TIA-associated aspect (OR = 53.4, 95% CI: 11.9-74.18, P = .001). ASA/B, common finds in general population, could carry a significant incremental possibility of association with TIA when concentric geometry, frequent hypertensive aspect, is present as well.
