Short-term functional outcome after hip resurfacing surgery.

Hip resurfacing arthroplasty is a popular method for treating late stage osteoarthritis, especially in young and active patients. Most studies presenting short-term follow-up after hip resurfacing present radiographic or dual clinician-patient-related outcome. These kinds of outcomes are influenced by interpretation of the clinician and do not tell us much about functional outcome from the patients perspective.

Emerging designs in orthopaedics: expertise-based randomized controlled trials.

In this article, we discuss the limitations of conventional randomized controlled trials (RCTs) in the surgical field. Surgeons are often believers in certain surgical techniques and therefore can be reluctant to learn new interventions. In expertise-based trials, the patients are randomized to surgeons with expertise in the intervention under investigation.

Cytogenetic analysis after evaluation of 750 fetal deaths: proposal for diagnostic workup.

Objective: To estimate success rates for cytogenetic analysis in different tissues after intrauterine fetal death, and study selection criteria and value of cytogenetic testing in determining cause of death.

Methods: Cytogenetic analyses and the value of this test in determining cause by a multidisciplinary panel were studied in 750 fetal deaths. Morphologic abnormalities, small for gestational age (SGA), advanced maternal age (older than 35 years) and maceration were studied as selection criteria.
