Hoffa fractures are associated with concomitant soft tissue injures and a high postoperative complication rate.

Introduction: Hoffa fractures are a rare and often overlooked entity. The main goal of surgical treatment is to restore the articular surface and maintain knee function. However, current clinical data indicate heterogeneous outcomes.

Anatomic repair and ligament bracing as an alternative treatment option for acute combined PCL injuries involving the posteromedial or posterolateral corner-results of a multicentre study.

Introduction: Combined PCL injuries involving the posteromedial/-lateral corner (PMC/PLC) usually require surgical management. Literature shows controversy regarding the standards of treatment. Suture-augmented repair leads to excellent results in acute knee dislocations but has not been investigated clinically in combined PCL injuries.

Background: Surgical drains are widely used despite limited evidence in their favor. This study describes the associations between drains and surgical site infections (SSI).

Methods: This prospective observational double center study was performed in Switzerland between February 2013 and August 2015.

Infection following fractures of the proximal tibia - a systematic review of incidence and outcome.

Background: To systematically review all available studies of operatively treated proximal tibia fractures and to report the incidence of superficial or deep infection and subsequent outcomes.

Methods: A systematic review of the literature in Medline, Cochrane, Embase and GoogleScholar was conducted to identify studies with cohorts of patients with infection after surgical treatment of proximal tibia fractures. Studies were included according to predefined inclusion and exclusion criteria.

Longitudinal study of a NoGo-P3 event-related potential component following mild traumatic brain injury in adults.

Background: Event-related potentials have repeatedly revealed electrophysiological markers of cognitive dysfunction associated with Mild Traumatic Brain Injury (MTBI) and may represent a sensitive tool to guide cognitive rehabilitative interventions. We previously found patients with symptomatic MTBI characterized by smaller P300 (or P3) wave amplitudes in a NoGo-P3 subcomponent in the acute phase of the injury. The goal of this longitudinal study was to investigate whether this early NoGo-P3 subcomponent differs over time in symptomatic MTBI patients and healthy controls.

Prefrontal Cortical Thickening after Mild Traumatic Brain Injury: A One-Year Magnetic Resonance Imaging Study.

The objective of this study was to evaluate group-by-time interactions between gray matter morphology of healthy controls and that of patients with mild traumatic brain injury (mTBI) as they transitioned from acute to chronic stages, and to relate these findings to long-term cognitive alterations to identify distinct recovery trajectories between good outcome (GO) and poor outcome (PO). High-resolution T1-weighted magnetic resonance images were acquired in 49 mTBI patients within 7 days and 1 year post-injury and at equivalent times in 49 healthy controls. Using linear mixed-effects models, we performed mass-univariate analyses and associated the results of the interaction with changes in cognitive performance.

Functional and Structural Network Recovery after Mild Traumatic Brain Injury: A 1-Year Longitudinal Study.

Brain connectivity after mild traumatic brain injury (mTBI) has not been investigated longitudinally with respect to both functional and structural networks together within the same patients, crucial to capture the multifaceted neuropathology of the injury and to comprehensively monitor the course of recovery and compensatory reorganizations at macro-level. We performed a prospective study with 49 mTBI patients at an average of 5 days and 1 year post-injury and 49 healthy controls. Neuropsychological assessments as well as resting-state functional and diffusion-weighted magnetic resonance imaging were obtained.

Connectomic and Surface-Based Morphometric Correlates of Acute Mild Traumatic Brain Injury.

Reduced integrity of white matter (WM) pathways and subtle anomalies in gray matter (GM) morphology have been hypothesized as mechanisms in mild traumatic brain injury (mTBI). However, findings on structural brain changes in early stages after mTBI are inconsistent and findings related to early symptoms severity are rare. Fifty-one patients were assessed with multimodal neuroimaging and clinical methods exclusively within 7 days following mTBI and compared to 53 controls.

Altered cognitive processes in the acute phase of mTBI: an analysis of independent components of event-related potentials.

Mild traumatic brain injuries (mTBI) generate acute disruptions of brain function and a subset of patients shows persisting cognitive, affective, and somatic symptoms. Deficits in the executive function domain are among the more frequent cognitive impairments reported by mTBI patients. By means of independent component analysis, event-related potential components from a visual cued go/nogo task, namely contingent negative variation (CNV) and NoGo-P3, were decomposed into distinct independent components that have been shown to be associated with the executive processes of energization, monitoring, and task setting.

Sports activity after surgical treatment of intra-articular tibial plateau fractures in skiers.

Background: Tibial plateau fractures occur frequently while participating in winter sports, but there is no information on whether skiers can resume sports and recreational activities after internal fixation of these fractures.

Hypothesis: Skiers can resume low-impact sports activity after internal fixation of tibial plateau fractures.

Study Design: Case series; Level of evidence, 4.

Biomechanical comparison of different fixation techniques for reconstruction of tibial avulsion fractures of the anterior cruciate ligament.

Purpose: The most common fixation techniques for tibial avulsion fractures of the anterior cruciate ligament (ACL) described in the literature are screw and suture fixation. The fixation of these fractures with the TightRope® device might be an alternative. Up to now it has been commonly used in other injuries, such as acromioclavicular joint or syndesmosis ruptures.

[A penetrating volar foreign body: a wooden splinter beneath the flexor tendons].

Hand injuries are among the most common injuries seen in general practitioner (GP) consultation hours and emergency departments and are most often affecting the dominant hand. We report on a case of unsuccessful primary exploration of the volar hand for a foreign body by the GP. In regard to detailed history of the injury mechanism, we performed the clinical examination and an additional ultrasound evaluation of the hand, suggesting evidence for a foreign body and a laceration of one of the flexor tendons.

Can complications of titanium elastic nailing with end cap for clavicular fractures be reduced?

Background: We found treatment of clavicular midshaft fractures using titanium elastic nails (TENs) in combination with postoperative free ROM was associated with a complication rate of 78%. The use of end caps reduced the rate to 60%, which we still considered unacceptably high. Thus, we explored an alternative approach.

[Alveolar adenoma--a rare pulmonary mass: case report and review of the literature].

This report describes the case of a 58-year-old man presenting with haemoptysis. Chest X-ray and CT scans showed a solitary pulmonary mass in the right lower lobe without radiographic signs of malignancy. Definitive histology following thoracoscopic wedge resection showed the distinctive findings of an alveolar adenoma, a very rare benign tumour of the lung of unknown histogenesis.

[Will broken glass bring luck?].

A 56 year old female patient presented to the emergency room because of a progressive, painful swelling of her thigh, clinically suspected to be a haematoma. Trauma was denied. Ultrasonography revealed a hyperechogenic structure, which appeared to be an intramuscular foreign body on computed tomography.
