Locking plating is a common surgical treatment of proximal humeral fractures with satisfactory clinical results. Implant-related complications, especially screw-related, have been reported, however, the lack of information regarding their onset, used surgical technique, complexity of the fracture, bone quality etc., prevents from understanding the causes for them. The aim of this systematic review is to identify the potential risk factors for late screw complications by gathering information about the patient characteristics, comorbidities, fracture types, surgical approaches and implant types. ⋯ Most of the latter were secondary screw perforations and screw cut-outs, being predominantly linked to poor bone quality, while screw loosening and retraction were found less frequently as a result of locking mechanism failure. Overall, the amount of information for complications was limited and screw perforation was the most frequent screw-related complication, mostly reported in female patients older than 50 years, following four-part or AO/OTA type C fractures and detected four weeks postoperatively. The sparse information in the literature could be an indicator that the late screw complications might have been under-reported and under-described, making the understanding of the screw-related complications even more challenging.

Review
Prehospital ultrasound in the management of trauma patients: Systematic review of the literature.
Emergency ultrasound methods such as Focused Assessment with Sonography in Trauma (FAST) are a widely used imaging method. This examination can be performed to examine the presence of several life-threatening injuries. Early diagnosis may lead to better outcome, but the effect of timely diagnosis in the prehospital setting is not yet clear. Therefore, the aim is to determine the diagnostic accuracy and the effect of prehospital ultrasound performed in (poly)trauma patients. ⋯ Prehospital ultrasound led to a change in polytrauma management in all studies that included this as an outcome measure. The diagnostic accuracy was described in eight studies, high sensitivity and specificity were found. Overall, the studies seem to suggest a positive influence of performing ultrasound. However, additional research with homogenous accuracy endpoints and uniformly trained prehospital care providers is recommended.

Multicenter Study
Changes in patellar fracture characteristics: A multicenter retrospective analysis of 1596 patellar fracture cases between 2003 and 2017.
This study aimed to investigate the characteristics of patellar fracture and the changes in these characteristics over time in Korea. ⋯ Patellar fractures in the female and elderly populations are increasing. Moreover, elderly patients with patellar fractures had a higher postoperative complication rate and also a higher percentage of low-energy injury than younger patients. Therefore, patellar fractures in the elderly population should be considered fragility fractures, and further studies are warranted to suggest a specific treatment plan for fragility patellar fractures.

Free flaps are the gold standard for reconstruction of the mandible, tongue and floor of the mouth. Free fibular flaps are the most preferable option for reconstruction of complex mandibular defects, as well as for tongue and mouth floor reconstruction, since they are harvested easily, present excellent sculptability and good functional outcomes. ⋯ Advances in computerized preoperative planning have allowed virtual simulation of the defect and fabrication of an individualized stereolithic mandibular model. This short review discusses the current trends of bone and soft tissue flaps for complex oromandibular reconstructions aiming to present a comprehensive review that the readers would find interesting and informative.

Elbow flexion is the first goal in upper partial brachial plexus palsy treatment. However, elbow extension is essential for daily living activities. To recover this function, one fascicle of ulnar nerve can be transferred to the branch of the long head of the triceps, but this procedure has been previously published in only two patients. ⋯ Because the harvested ulnar nerve motor fascicle is close to the branch of the long head of the triceps, the recovery time for this procedure is shorter than that of other described nerve transfers. The isolated recovery of the reinnervated long head of the triceps muscle excludes spontaneous recovery occasionally noted in upper root plexus injuries. The transfer of one fascicle of ulnar nerve to the branch of the long head of the triceps is reliable for active elbow extension recovery in C5, C6 and C7 brachial plexus palsies.
