Background:
To compare the long-term functional outcomes of patients surgically treated for Weber B ankle fractures with or without syndesmotic fixation.
Methods:
In total, 959 adult patients with previous treatment with open reduction and internal fixation (ORIF) for closed ankle fractures were eligible for inclusion in a cross-sectional postal survey 3-6 years after surgery; 645 had Weber B fractures. The survey assessed functional outcomes with three validated ankle questionnaires.
Results:
In total 365 (57%) patients responded at a median of 4.2 years after the trauma. After adjusting for age, sex, education, smoking status, body mass index, diabetes, physical status before surgery, fracture classification, and duration of surgery, patients with a syndesmotic fixation had no different OMAS score (p = 0.98), LEFS score (p = 0.61), and SEFAS score (p = 0.98) than those without a syndesmotic fixation. Trimalleolar fracture was associated with worse functional outcomes than unimalleolar on two of the scales, the OMAS (p = 0.028) and LEFS (p = 0.046).
Conclusions:
In multivariable analysis, patients with a syndesmotic fixation had no worse long-term functional outcomes than those without syndesmotic fixation.

Predicting Reaction Outcomes
Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
Outcomes of Glycolysis
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...
