Both mechanical and biological theories have been proposed in the development of non-union. The mechanical theory suggests that a high strain environment in a fracture will predispose it to non-union. While in simple fractures and wedge fractures there are only one and two primary fracture planes respectively, in multi-fragmentary fractures there are many and a non-union may form along any of the original fracture lines, however the plane which experiences the highest strain is at 45O - the shear plane. We hypothesise that in multi-fragmentary fractures the initial fracture line that most often fails to unite will tend towards the plane with the highest strain. ⋯ Prognostic level 3.

The prophylactic intravenous antibiotic regimen for Gustilo-Anderson Type III open fractures traditionally consists of cefazolin with an aminoglycoside plus penicillin for gross contamination. Cefotetan, a second-generation cephalosporin, offers a wide spectrum of activity against both aerobes and anaerobes as well as against Gram-positive and Gram-negative bacteria. Cefotetan has not been previously established within orthopedic surgery as a prophylactic intravenous agent. ⋯ Level III Retrospective Cohort Study.

The study aimed to explore the effect of differing volar locking plate (VLP) prominence on the median nerve (MN) in distal radius fracture (DRF) with ultrasound assistance to guide clinical treatment. ⋯ Differing plate protrusions in DRF treatment did not cause clinical symptoms during follow-up; however, excessive plate protrusion (Soong Grade 2) increased the cross-sectional area of the MN. We recommend placing the plate as proximal as possible during VLP treatment of DRFs to avoid excessive bulges affecting the MN.

There is a paucity of research in the rates for sepsis and septic shock in the hip fracture population specifically, despite marked clinical and prognostic differences between these conditions. The purpose of this study was to determine the incidence, risk factors, and mortality rates for sepsis and septic shock as well as evaluate potential infectious causes in the surgical hip fracture population. ⋯ The incidence of sepsis and septic shock after hip fracture surgery was 1.0% and 0.6%, respectively. The 30-day mortality rate was 16.2% in patients with sepsis and 40.8% in patients with septic shock. Potentially modifiable risk factors for both sepsis and septic shock were anemia and hypoalbuminemia. Urinary tract infections, pneumonia, and surgical site infections preceded the majority of cases of sepsis and septic shock. Prevention, early identification, and successful treatment of sepsis and septic shock are paramount to lowering mortality after hip fracture surgery.

Percutaneous osteosynthesis of acetabular fractures with quadrilateral plate involvement using an infra-pectineal plate through a new paramedial approach using cadaveric specimens. ⋯ The paramedial approach is safe with direct access to key anatomical structures for acetabular osteosynthesis. Infrapectineal with reverse fixation plate osteosynthesis provides an excellent reduction rate and good stability once the implants act against displacement forces, making it possible to direct them freely. Further clinical and biomechanical trials are required to confirm our findings. We believe that there was an improvement of up to 60% in the result quality for some cases; however, this technique must be compared with other techniques. Evidence Level IV (Experimental Trial).
