This investigation develops a predictive model for loss of alignment (LOA) following fixation of open tibia fractures. ⋯ Increasing age and BMI are associated with LOA and segmental fracture amplifies the protective effect of IMN versus EF. The importance of LOA as a surrogate outcome after operative treatment of open tibial fractures is supported by its association with inferior radiographic and functional patient outcomes.

The importance of routine follow-up of several relatively simple stable injuries (SSIs) is questionable. Multiple studies show that direct discharge (DD) of patients with SSIs from the Emergency Department results in patient outcomes and experiences comparable to 'standard care' with outpatient follow-up. The purpose of this study was to evaluate to which extent DD of SSIs has been adopted amongst trauma and orthopedic surgeons internationally, and to assess the variation in the management of these common injuries. ⋯ Despite available evidence, DD of SSIs has not been widely adopted worldwide. Practice variation still exists even for these common injuries. This variation suggests inefficiency and consequently unnecessarily high healthcare costs. (Orthopaedic) trauma surgeons are encouraged to evaluate their current treatment protocols of SSIs.

The lesser trochanter (LT) fragment in the multifragmentary intertrochanteric femur fracture (AO 31A2.2) may extend distally. If the fragment extends too distally, fixation with a short proximal femoral nail antirotation (PFNA-II) device may not be sufficient. The exact length of distal extension that can be tolerated by the short PFNA-II is not known, therefore it is our objective to determine it. ⋯ A long PFNA-II should be considered when fixing a multifragmentary intertrochanteric fracture if the LT fragment extends 40mm distal to the distal base of the LT as the construct fails rapidly upon uniaxial load to failure. Clinically, this threshold may be smaller to account for the multi-axial and dynamic stresses.

Denervation leads to severe atrophy of neuromuscular junction (NMJ) structure including decrease of the expression of fundamental proteins. Up to now, conventional suture has been the gold standard method used to correct this injury. Fibrin sealant is one of the alternatives proposed to optimize this method. ⋯ There was an increase of relative planar area in these groups (SL and SFS) highlighting that there was less nAChRs fragmentation and the values of protein expression showed return of nAChRs to mature pattern. Use of HFB associated with a single suture stitch decreased surgical time, minimized suture injuries, did not alter nerve regeneration and presented potential to reestablish the NMJ apparatus. These consolidated results encourage surgeons to develop future clinical trials to install definitively this new approach both for reconstructive surgery and neurosurgery.

Percutaneous fixation of Lisfranc injuries is potentially less invasive to traditional open techniques but evidence of any clinical benefit is lacking. The aim of this study is to compare the clinical outcomes of percutaneous reduction and internal fixation (PRIF) of low energy Lisfranc injuries with a matched, control group of patients treated with ORIF. ⋯ PRIF of low energy Lisfranc injures is a safe, minimally invasive technique and is associated with better mid-term clinical outcomes compared to ORIF.
