The purpose of this study was to compare imaging modalities in the diagnosis of occult radial head and neck fractures and to assess the diagnostic value of ultrasound in diagnosing occult fractures of the radial head and neck. The study included 193 patients (101 male, 92 female) who were referred by trauma surgeons from January 2011 to July 2014 and presented with history of acute elbow trauma. The mean age of the patients was 37 years (range 15-82 years); 95 right and 98 left elbows were included in the study. ⋯ In conclusion, ultrasound imaging proved to be an effective method for diagnosing occult fractures of the radial head or neck when initial radiograms showed only intraarticular effusion. Ultrasound imaging is a cost-effective, easy-to-use and radiation-free method. For these reasons we recommend it for early detection of occult fracture in the emergency room.

Cortical onlay strut allografts, as the primary method of fixation or as a supplementary fixation when a plate is used, have been a common option to treat B1 and C type PFF in the past decades since the technique was described by Penenberg et al. in 1989. Strut grafts were described as a useful treatment option because they provide structural support to the internal fixation while increasing the host bone stock without the harvesting complications. ⋯ Other concerns are the role as disease carrier, immune reactions, incorporation to the host bone in the long term and, in some centres, the availability and costs. This article reviews the literature regarding the use of struts in PFF and provides an overview on the use of strut grafts with actual recommendations based on the authors experience and the data from literature.

Randomized Controlled Trial
Precise placement of lag screws in operative treatment of trochanteric femoral fractures with a new guide system.
We assessed the accuracy of a new guide system that we developed to place lag screws in the proper position with the minimum number of attempts for operative treatment of trochanteric femoral fractures. ⋯ With this new guide system, we are able to insert lag screws successfully in the optimal position even in most unstable fractures. The present study indicated that this new guide system and nail facilitate accurate placement of lag screws in the appropriate position with the minimum number of attempts.

Traumatic brain injury (TBI) is divided into primary and secondary brain injury. Primary brain injury occurs at the time of injury and is the direct consequence of kinetic energy acting on the brain tissue. Secondary brain injury occurs several hours or days after primary brain injury and is the result of factors including shock, systemic hypotension, hypoxia, hypothermia or hyperthermia, intracranial hypertension, cerebral oedema, intracranial bleeding or inflammation. ⋯ The lungs and urinary tract were the most common sites of infection. In conclusion, elevated inflammatory markers (white blood cell count and CRP) and hyperglycaemia are associated with secondary brain injury. The lack of routine use of intracranial pressure (ICP) monitoring may explain the high mortality rate and the occurrence of secondary stroke in patients with TBI.

Randomized Controlled Trial
The effect of ankle brace type on braking response time-A randomised study.
The question whether or not a patient with an ankle brace should drive a car is of obvious importance because brake response time (BRT) is considered one of the most important factors for driving safety. ⋯ In conclusion, right-sided ROM restricting ankle braces involve significant impairment of BRT in healthy participants. No such prolonged BRT was found for an elastic ankle bandage or the ligament brace.
