Early migration characteristics of a 180° porous-coated cup with 1-mm press fit.
Evaluation of early cup movement is an important diagnostic tool to predict the likelihood of long-term implant loosening and clinical failure. The investigated cementless cup is clinically proven over 10 years, but there is a paucity of information that accurately describes the migration characteristics of this component. ⋯ Surgeons may expect to find a variable amount of early migration when using the Pinnacle cup. To our knowledge, these are the first results, which show an early "impaction" of a cementless cup, followed by subsequent osseointegration. We believe that an appropriate long-term outcome of the investigated cup is ensured. The data of the present investigation will provide clinicians with useful baseline information with which to compare new cup designs.

Comparative StudyLocking versus standard screw fixation for acetabular cups: is there a difference?
Total hip replacement has been established as a valid treatment option for displaced subcapital fractures. However, insufficient primary fixation may be the reason for early loosening in these osteoporotic patients. Primary fixation of the cup is usually achieved by press-fit fixation that can be enhanced using screws. Locking the screws into their respective cups may seem to improve the primary fixation of the construct, as locked plates proved superior fixation for osteoporotic fractures. ⋯ These experimental results indicate that acetabular screws enhance primary cup fixation. This may become significant in conditions where the acetabular bone stock is suboptimal, such as when performing total hip arthroplasty after displaced subcapital fractures. However, there is no superiority for locked screws over standard screw fixation.

Meta AnalysisRisk factors for deep infection after total knee arthroplasty: a meta-analysis.
Estimated the risk factors for postoperative infection after total knee arthroplasty (TKA) to prevent its occurrence. ⋯ There were positive evidences for some certain factors which could be targeted for prevention of the onset of infection, but more studies are needed to define the association of some other controversial factors in infection, like osteoarthritis, gender and so on. The quality of studies also needs to be improved.

Randomized Controlled Trial Comparative StudyNon-bridging external fixation employing multiplanar K-wires versus volar locked plating for dorsally displaced fractures of the distal radius.
The aim of this study was to compare non-bridging external fixation to palmar angular stable plating with respect to radiological outcome, wrist function, and quality of life. ⋯ Non-bridging external fixation employing multiplanar K-wires is a suitable treatment option in intra- and extra-articular fractures of the distal radius even in osteoporotic bone.

ReviewEfficacy of treatment in peri-pelvic Morel-Lavallee lesion: a systematic review of the literature.
Morel-Lavallee lesion (MLL) of the peri-pelvic region is less common and various treatments have been introduced to manage the lesion. No standard treatment is recommended. We performed a systematic review of literature to (1) identify the classification of peri-pelvic MLL; (2) review the treatments of the lesion and their complications; (3) define the optimal treatment of peri-pelvic MLL. ⋯ Peri-pelvic MLL can be treated with various surgical methods depending on the formation of fibrosis capsule and associated injuries. Dead space closure technique is emphasized in the treatment of MLL. Higher quality of literature is required to prove this result in future research.
