Multicenter StudyDistal radius malunion increases risk of persistent disability 2 years after fracture: a prospective cohort study.
Studies concerning the relationship between distal radius fracture malunion and a persistent arm-related disability have produced conflicting results. ⋯ After distal radius fracture, arm-related disabilities are more likely to persist at least 2 years in patients with fractures that healed with shortening and dorsal angulation than in patients with only shortening or dorsal angulation or without malunion.

ReviewTrends in use of total knee arthroplasty in Korea from 2001 to 2010.
The use of total knee arthroplasty (TKA) has increased substantially in most Western countries. However, the trends in TKA use and changes in demographic characteristics of patients having TKA in Korea remain unclear. ⋯ During the past decade, TKA use in Korea has markedly increased and caught up with the use levels of most developed Western countries. Trends toward consistent growth in elderly patients and higher rates in females were observed. Appropriate healthcare strategies reflecting these trends in demographics are urgently needed in Korea.

Multicenter StudyWhat are the causes of revision total knee arthroplasty in Japan?
There is limited information regarding the cause of revision TKA in Asia, especially Japan. Owing to differences in patient backgrounds and lifestyles, the modes of TKA failures in Asia may differ from those in Western countries. ⋯ The revision burden at the five referral centers in Hokkaido was 3.3%, and the most common cause of revision TKA was mechanical loosening followed by infection. Demographic data such as age and sex might be associated with particular causes of revision TKA.

Femoral lateral bowing and varus condylar orientation are prevalent and affect axial alignment of TKA in Koreans.
Coronal alignment is considered key to the function and longevity of a TKA. However, most studies do not consider femoral and tibial anatomical features such as lateral femoral bowing and the effects of these features and subsequent alignment on function after TKA are unclear. ⋯ Lateral femoral bowing, varus condylar orientation, and severe varus inclination of the tibia plateau should be considered when performing TKA in Korean patients or patients with otherwise similar anatomical features.

Comparative StudyCharlson comorbidity indices and in-hospital deaths in patients with hip fractures.
The Charlson Comorbidity Index (CCI) and its modifications are comorbidity-based measures that predict mortality. It was developed for patients without trauma and inconsistently predicted mortality and adverse events in several previous studies of patients with trauma. ⋯ While all three CCI variations predicted in-hospital mortality in patients with hip fractures, other factors may be of value in patients with trauma.
