The purpose of this retrospective study was to assess the effect of the reduced medialisation of the Arrow reverse shoulder prosthesis on short-term clinical and radiological results. The clinical and radiological results of 47 Delta III reverse prostheses and 49 Arrow reverse prostheses were retrospectively compared at a minimum of twelve months follow-up. There was a significant increase (p <...

The authors have retrospectively studied a series of 32 reverse shoulder prostheses implanted in 30 patients by the same surgeon between 1992 and 2000. The mean age was 71 years; 26 patients were female, 4 were male. Thirteen patients (14 prostheses) were clinically and radiologically examined at follow-up; 9 patients (10 prostheses) were questioned by telephone and their radiological records w...

OBJECTIVES To construct reference ranges of uterine artery Doppler parameters against gestation in twin pregnancies and to present charts of the pulsatility index (PI) and resistance index (RI) for clinical use. METHODS This was an observational study of the uterine circulation in 557 women with dichorionic twin pregnancies at 17-38 weeks' gestation. Uterine artery measurements were performed...

OBJECTIVE To evaluate the clinical and radiological results and the impact on quality of life of the reverse shoulder arthroplasty. METHODS Retrospective case series evaluating 13 patients undergoing reverse shoulder arthroplasty with at least two years of clinical follow-up. Clinical evaluation was performed before and after surgery with the ASES and VAS scales and hand-mouth, hand-neck, and...

OBJECTIVE To statistically analyze the long-term results of alar base reduction after rhinoplasty. METHODS Among a consecutive series of 100 rhinoplasty cases, 19 patients required alar base reduction. The mean (SD) follow-up time was 11 (9) months (range, 2 months to 3 years). Using preoperative and postoperative photographs, comparisons were made of the change in the base width (width of ba...

Short-term femoral neck fracture is a primary complication associated with contemporary hip resurfacing. Some fractures are associated with neck notching, while others occur in the absence of notching. These unexplained fractures may be due to large magnitude strains near the implant rim, which could cause bone damage accumulation and eventual neck fracture. We used statistically augmented fini...

This study describes the prevalence and characteristics of noise-induced hearing loss (NIHL) in student musicians (N = 329) aged 18-25 years. Students completed a questionnaire regarding exposures before a hearing assessment. NIHL was defined by the presence of a notch 15 dB in depth at 4000 or 6000 Hz relative to the best preceding threshold. Overall prevalence of NIHL was 45%, with 78% of not...

Early repolarization pattern (ERP) is a common ECG variant, characterized by J point elevation manifested either as terminal QRS slurring (the transition from the QRS segment to the ST segment) or notching (a positive deflection inscribed on terminal QRS complex) associated with concave upward ST-segment elevation and prominent T waves in at least two contiguous leads.1,2 The J point deflection...

BACKGROUND Reverse total shoulder arthroplasty (RSA) is a recent concept that enables good functional outcomes in cases of massive rotator cuff tear and cuff tear arthropathy. Design parameters influence the functional results and complications. The purpose of this study is to present the results of a novel RSA, the Total Evolutive Shoulder System (TESS; Biomet, Warsaw, IN, USA), based on a rev...
