What is the relationship between number of publications during orthopaedic residency and selection of an academic career?
Although many residents partake in academic pursuits, including the publication of clinical studies, laboratory research, case reports, and review articles, it is uncertain whether such experiences are associated with a career-long interest in an academic orthopaedic career. ⋯ Graduates of our orthopaedic residency program who pursued an academic career were likely to have published more articles during residency compared with their nonacademic peers.

Fixation, survival, and dislocation of jumbo acetabular components in revision hip arthroplasty.
Acetabular revision of a total hip arthroplasty using jumbo components (Mayo definition, ≥62 mm in women and ≥66 mm in men) offers distinct advantages in patients with notable acetabular bone loss. However, there are little data on the long-term survival and complications associated with use of these components. ⋯ Jumbo acetabular components with screw fixation were associated with low rates of infection and loosening after revision total hip arthroplasty and had high survival at fifteen years. Reoperation for wear and loosening increased in the second decade. Dislocation was the most common complication and was significantly associated with smaller femoral head sizes.

Clinical TrialSix-degrees-of-freedom cervical spine range of motion during dynamic flexion-extension after single-level anterior arthrodesis: comparison with asymptomatic control subjects.
The etiology of adjacent-segment disease following cervical spine arthrodesis remains controversial. The objective of the current study was to evaluate cervical intervertebral range of motion during dynamic flexion-extension in patients who had undergone a single-level arthrodesis and in asymptomatic control subjects. ⋯ C5/C6 arthrodesis does not affect the total range of motion in adjacent vertebral segments, but it does alter the distribution of adjacent-segment motion toward more extension and less flexion superior to the arthrodesis and more posterior translation superior and inferior to the arthrodesis during in vivo functional loading. Range of motion measured from static full-flexion and full-extension images underestimates dynamic range of motion. Clinical evaluation of excessive anterior-posterior translation should take into account the cervical vertebral level.

Repair integrity and functional outcomes for arthroscopic margin convergence of rotator cuff tears.
We evaluated the clinical outcomes of arthroscopic margin convergence for rotator cuff tears. ⋯ Reducing tension by margin convergence followed by a repair of the resulting free edge to bone has reasonable short-term clinical results but a substantial retear rate (47.8%). However, the retears tended to be smaller than the original tear size. No significant difference was observed in the short-term clinical results between the groups with or without a retear.
