The loss of pre-fracture basic mobility status is associated with increased mortality and any readmission after hip fracture. However, it is less known if the loss of pre-fracture mobility has impact on acquiring a post-discharge infection. ⋯ In this large national cohort study, we found that loss of pre-fracture basic mobility status upon hospital discharge was strongly associated with 30-day post-discharge risk of developing infection. These findings suggest a clinical importance of carefully focusing on regaining the pre-fracture basic mobility before discharging the patient.

Interprosthetic femoral fractures (IFF) are rare but increasing with an ageing population. Operative management is challenging and there is currently a paucity of outcome data in literature. The purpose of this study was to evaluate outcomes of IFFs managed with modern distal femoral locking plates, in a larger sample size than previously published. ⋯ IFFs are occurring with increasing frequency in a frail elderly population. In patients with IFFs, MIPO and biological fixation techniques using modern distal femoral locking plates can achieve high rate of union when combined with immediate unrestricted weight bearing postoperatively.

The correct choice of surgical approaches in complex tibial plateau fractures is essential to achieve adequate reduction and fixation. Detailed fracture morphology and direction of columns displacement, that we have named the Main Deformity Direction (MDD), may aid in selecting the optimal surgical strategy. In this article we present a new algorithm based on MDD and column concepts. The aim of this study was to evaluate the outcomes of a group of tibial plateau fractures treated according to this algorithm. The secondary aim was to evaluate the incidence of the different MDD in our multicolumnar subgroup. ⋯ Satisfactory results have been obtained following the principles of our algorithm. In addition to the anatomical involvement of columns and segments, we believe that identifying the Main Deformity Direction (MDD) provides useful information for decision-making, especially in multicolumnar fractures. The most frequent MDD in our multicolumnar subgroup was the posteromedial MDD, but more than one-third presented a different MDD, requiring different surgical strategies.

Instability of the distal radioulnar joint (DRUJ) commonly results from traumatic disruption of the distal radioulnar ligaments of the triangular fibrocartilage complex (TFCC). Treatment of this rupture typically requires immobilization of the wrist and elbow for a period of 6 to 8 weeks. This study evaluated the hypothesis that treatment of DRUJ instability with dynamic stabilization would allow early mobilization of both the radiocarpal and distal radioulnar joints by the first postoperative week without compromising restoration of TFCC integrity. ⋯ Acute DRUJ instability treated with dynamic stabilization led to satisfactory clinical outcomes in terms of range of motion, pain relief and joint stability, allowing DRUJ movement from the first postoperative week. This technique represents a simple, reproducible and minimally invasive procedure with a low rate of implant related complications.

Spinopelvic lesions are the result of high-energy vertical trauma with axial skeletal overload where the spine impacts onto the sacrum, dissociating the lumbar spine from the pelvis. Therefore, lumbopelvic instrumentations are aimed to counteract these vertical forces, although various biomechanical aspects of the combinations of different constructs (with or without iliosacral screws) or the number of lumbar fixation levels (L5 or the combination of L5 with L4) are subject to controversy. ⋯ In this paper the methodology for laboratory studies is discussed. The design of the test bench fixture, biomechanical testing protocol and data analysis are very important when inference to the clinical setting is desired.
