Long-term outcomes after different types of Horne and Tanzer olecranon fractures.
It is unclear whether the outcomes differ after different Horne and Tanzer types of olecranon fractures. ⋯ All types of Horne and Tanzer olecranon fractures have favourable long-term outcome. Elbow joint space reduction is associated with inferior subjective elbow function while degenerative changes are not.

Inducing pilon fractures in human cadaveric specimens depending on the injury mechanism: a fracture simulation.
Operative management of pilon fractures, especially high-energy compression injuries, is a challenge. Operative education is of vital importance to handle these entities. Not rarely, it is cut by economics and staff shortage. As public awareness toward operative competence rises, surgical cadaver courses that provide pre-fractured specimens can improve realism of teaching scenarios. The aim of this study is to introduce a realistic pilon fracture simulation setup regarding the injury mechanism. ⋯ III.

Effects of ethnicity on proximal femoral intramedullary nail protrusion-a 3D computer graphical analysis.
Antegrade nailing of proximal femur or femoral shaft fractures is a proven treatment with good to excellent results. Nonetheless, clinical evidence from Asia indicates that proximal femur nails can be too proud at the greater trochanter (GT) causing irritation for some Asian patients. This study aimed to identify any significant differences in proximal nail misfit for a set of Asian and Caucasian femora. ⋯ This study illustrated a significantly increased incidence of proximal nail protrusion in Asian compared to Caucasian femora, corroborating clinical findings. The combination of shorter stature and GT height and a larger CCD angle in Asians likely contributes to this difference.

A new criterion for assessing Ilizarov treatment outcomes in nonunion of the tibia.
The purpose of this study was to assess a population of patients with nonunion of the tibia treated with the Ilizarov method in terms of achieved union rates and maintained union rates, determination of re-fracture factors, with a subsequent comparison of our findings with those reported in the available literature. ⋯ All patients in our study achieved bone union, which constitutes a better outcome than those reported on average in the literature (73.7-100%). The mean length of time which the Ilizarov external fixator was in place in our patients was 8.3 months, which is consistent with the data from literature. Infection, atrophic nonunion, nonunion in 1/3 distal of tibia, and close surgery technique are risk factors of re-fracture. None of the analyzed studies assessed the proportion of patients with maintained bone union. In our study, maintained bone union was observed in 95.1% of patients at the follow-up visit at least 2 years after treatment, which indicates excellent long-term treatment outcomes in nonunion of the tibia treated with the Ilizarov method.

Open reduction and internal fixation might be a valuable alternative to stem revision in Vancouver B2 periprosthetic femoral fractures, irrespective of the stem's design.
The purpose of this study was to compare the clinical and radiological outcomes following open reduction and internal fixation (ORIF) of Vancouver B2 periprosthetic femoral fractures versus stem revision (SR) surgery. ⋯ Level III.
