Comparative Study
Does intra-articular load distribution change after lateral malleolar fractures? An in vivo study comparing operative and non-operative treatment.
The impact of isolated malleolar fractures on the intra-articular load distribution within the ankle joint has been studied in several biomechanical cadaver studies during the last decades. Recently, computed tomography osteoabsorptiometry (CT-OAM) has been proposed as a valuable tool to assess intra-articular joint load distribution in vivo. The purpose of this retrospective matched pair analysis was to apply CT-OAM to evaluate in vivo changes of talar load distribution after lateral malleolar fractures in patients treated with open anatomic reduction and internal fixation (ORIF) compared to patients treated non-operatively. ⋯ Level III, retrospective cohort study.

Review Meta Analysis
The influence of tracheostomy timing on outcomes in trauma patients: A meta-analysis.
This study aims to assess the influence of tracheostomy timing on outcomes among trauma patients, including mortality, medical resource utility and incidence of pneumonia. ⋯ Evidence of this meta-analysis supports the dimorphism in some clinical outcomes of trauma patients with different tracheostomy timing. Additional well-designed randomized controlled trials (RCTs) are needed to confirm it in future.

The incidence of geriatric acetabular fractures continues to increase due to demographic changes. In the elderly, anterior column fractures are common, and standard approaches are associated with a considerable risk for surgery-associated complications. Therefore, a minimally invasive approach was developed in our department. The aim of this study was to examine early and mid-term results regarding the use of this novel two-incision minimally invasive (TIMI) approach in patients aged over 55 years with acetabular fractures. ⋯ Therapeutic Level II (Prospective cohort study).

Comparative Study
Finite element analysis of the three different posterior malleolus fixation strategies in relation to different fracture sizes.
Appropriate fixation method for the posterior malleolar fractures (PMF) according to the fracture size is still not clear. Aim of this study was to evaluate the outcomes of the different fixation methods used for fixation of PMF by finite element analysis (FEA) and to compare the effect of fixation constructs on the size of the fracture computationally. ⋯ Progressively increasing fracture size demands more stable fixation construct because RD increases significantly. Posterior buttress plate produces superior stability and lowest RD in PMF models irrespective of the fragment size.

The psoas minor partially inserted to the superior pelvic brim. And the plate used to fix the acetabular fracture has always been positioned at the pelvic brim after reduction through the Stoppa approach. However, there are few studies depicting the clinical significance of the psoas minor. The purpose of this paper was to explore the relationship between the insertion of the psoas minor tendon at the pelvic brim (IPMTPB) and screw placement through the Stoppa approach. ⋯ IPMTPB could be used as an anatomic landmark of safe zones for screw placement through the Stoppa approach. For cases without a psoas minor, the zones for extra-articular screw placement could be determined through the measurements in this paper.
