BACKGROUND Although ceramic-on-ceramic bearings for total hip arthroplasty (THA) show promising results in terms of bearing-surface wear, fracture of the bearing, insertional chips, and squeaking remain a concern. QUESTIONS/PURPOSES Our primary objective of this report was to determine overall survivorship of a titanium-encased ceramic-on-ceramic bearing couple. Our secondary objectives were ...

BACKGROUND The short-term results of modified Brostrom procedures (MBP) have been satisfactory. However, the long-term results of anatomical reconstruction have been less frequently reported. We report on our long-term results in our patient group. MATERIALS AND METHODS Thirty patients with chronic ankle instability who were treated using the MBP without CFL reconstruction from March 1997 to ...

PURPOSE We determine the safety and feasibility of magnetic resonance image guided transurethral ultrasound prostate ablation using active temperature feedback control in a preclinical canine model with 28-day followup. MATERIALS AND METHODS After a long acclimatization period we performed ultrasound treatment in 8 subjects using the magnetic resonance image guided TULSA-PRO™ transurethral ul...

OBJECTIVE To investigate the frequency of remaining pain in early rheumatoid arthritis (RA) after 3 months of treatment with methotrexate as the only disease modifying antirheumatic drug, with a special focus on patients with a good clinical response. METHODS The study base was cases reported to a population-based early RA cohort who had followup data from the Swedish Rheumatology Quality Reg...

PURPOSE We updated our experience with a strategy of expectant treatment for men with stage T1c prostate cancer and evaluated predictors of disease intervention. MATERIALS AND METHODS A total of 407 men with a median age of 65.7 years (range 45.8 to 81.5) with stage T1c (99.8%) or T2a (0.2%) prostate cancer suspected of harboring small volume prostate cancer based on needle biopsy findings an...

Povzetek. V prispevku sta predstavljena postopka za brezsenzorsko ugotavljanje začetne lege elektronsko komutiranih motorjev (EKM). Metodi temeljita na merjenju sprememb induktivnosti treh statorskih navitij, ki nastanejo zaradi različne intenzivnosti nasičenja geometrijsko pogojenega magnetnega tokokroga, ob vzajemnem delovanju magnetov na rotorju in tokovno vzbujanih statorskih navitjih. Indu...

UNLABELLED Compressive osseointegration technology, which provides immediate, mechanically compliant endoprosthetic fixation, has been adapted for massive proximal tibial reconstructions in an attempt to avoid aseptic failure encountered with conventional stems. A retrospective review of 16 patients with resected tumors was undertaken to determine whether compressive osseointegration can provid...

Background. We assessed risk of burnout in GPs during a 7-year followup and examined whether (1) thoughts about changing medical specialty increased the risk of burnout and (2) burned out GPs had higher job turnover rates than burnout-free GPs. Methods. In 2004 and 2012, all GPs in the county of Aarhus, Denmark, were invited to participate in a survey. Retirement status of physicians who partic...
