The role of serum C-reactive protein in the diagnosis of periprosthetic shoulder infection.
There is a paucity of literature regarding serum C-reactive protein (CRP) in the evaluation of a shoulder periprosthetic joint infection (PJI). The purpose of the current study was to establish cutoff values for diagnosing shoulder PJI and evaluate the influence of the type of infecting microorganism and the classification subgroups according to last proposed International Consensus Meeting (ICM) criteria on the CRP level. ⋯ Diagnostic Level III.

Hip kinematics and kinetics in patients with femoroacetabular impingement syndrome before and 1 year after hip arthroscopic surgery. Results from the HAFAI cohort.
Patients with femoroacetabular impingement syndrome (FAIS) experience decreased function. Consequently, earlier studies have evaluated gait biomechanics in these patients, but a larger study evaluating gait biomechanics before and after an intervention standardising gait speed is lacking. We aimed at investigating gait kinematics and kinetics in patients with FAIS compared with pain-free controls before and 1 year after hip arthroscopic surgery. Secondary, we aimed at analysing gait pattern separately for the sexes and to investigate associations between peak kinematics and kinetics and the Copenhagen Hip and Groin Outcome Score (HAGOS). ⋯ Gait pattern was only vaguely altered in patients with FAIS compared with pain-free controls before and after surgery when using at standardised gait speed. Hence, analysing gait in patients with FAIS does not seem of major importance. Nevertheless, there was an association between HAGOS Sports function and peak kinematics and kinetics in male patients, implying that there could be a clinical importance.

CT analysis of femoral malrotation after intramedullary nailing of trochanteric fractures.
Functional results after internal fixation of trochanteric femoral fractures may be negatively affected by healing in a non-physiological position. The aim of this study was to evaluate the occurrence and severity of femoral malrotation after nailing of trochanteric fractures. ⋯ Improper reduction of a trochanteric fracture is a common problem that can lead to femur malrotation. In our study, a rotational error greater than 15° occurred in 35% of the patients, but none of the monitored factors represented a statistically significant risk for this complication.

Comparative StudyHigher sensitivity with the lever sign test for diagnosis of anterior cruciate ligament rupture in the emergency department.
The objective of this study was to assess the diagnostic value of the "lever sign test" to diagnose ACL rupture and to compare this test to the two most commonly used, the Lachman and anterior drawer test. ⋯ When investigating acute ACL ruptures (< 8 days) in the ED, the lever sign test offers a sensitivity of 92.5%, far superior to that of other well-known clinical tests. The lever sign test is relatively pain-free, easy to perform and its visual interpretation requires less experience. Positive lever sign test at the ED should lead to an MRI to combine high clinical sensitivity with high MRI specificity.

Substantial changes in fracture rates in German hospitals in 2018 compared with 2002: an epidemiological study.
The aim of this study was to present recent epidemiological data on extremity and axial skeletal fractures in German hospitals and to compare them with older data to detect time trends. ⋯ The increase in the absolute fracture rates was due to increased rates of femur, shoulder, upper arm, forearm, and axial skeletal fractures, with elderly women being the main contributors. Femur fractures were found to be the most common fractures treated in German hospitals.
