Randomized Controlled Trial Multicenter Study Comparative Study
Below-elbow cast for metaphyseal both-bone fractures of the distal forearm in children: a randomised multicentre study.
Minimally displaced metaphyseal both-bone fractures of the distal forearm in children are often treated with an above-elbow cast (AEC). Treatment with a below-elbow cast (BEC) could give more comfort, but might lead to fracture displacement reducing pronation and supination. Because this has not been systematically investigated, we set up a randomised multicentre study. The purpose of this study was to find out whether BEC causes equal limitation of pronation and supination but with higher comfort level, compared with AEC. ⋯ Children with minimally displaced metaphyseal both-bone fractures of the distal forearm should be treated with a below-elbow cast.

The majority of periprosthetic fractures around the knee occur at the supracondylar region of the distal femur. Fixation of distal femoral fractures in osteoporotic bone with short segment remains a challenge, especially after total knee arthroplasty (TKA). Internal fixation of these fractures using locking plates has become popular. The purpose of this study was to evaluate a consecutive series of periprosthetic supracondylar femoral fractures treated with locked periarticular plate fixation with regard to surgical procedure, complications and clinical outcome. ⋯ Operative fixation of periprosthetic distal femoral fractures after TKA continues to be challenging. Notching of the anterior femoral cortex should be avoided. Loss of reduction and high failure rates still occur with locked plating and may be related to underlying factors. Indirect reduction and submuscular plate insertion technique reduce nonunion risk.

Comparative Study
Biomechanical analysis of second-generation headless compression screws.
Headless Compression Screws (HCS) are commonly utilized for the fixation of small bone and articular fractures. Recently several new second generation HCS (SG-HCS) have been introduced with the purported benefits of improved biomechanical characteristics. We sought to determine and compare the biomechanical efficiencies of these screws. ⋯ All SG-HCS demonstrated greater biomechanical characteristics than the first generation Herbert-Whipple screw. The Mini-Acutrak 2 with a variable pitch design generated the maximum compression force and showed the most reliability and sustainability. Screws with independently rotating trailing heads (Twinfix and Kompressor Mini) demonstrated loss of compression with extra turns. The increase of fastening torque due to over-fastening and loss of compression at the same time in some screw designs, demonstrated how the fastening torque (applied by the surgeon) can be a misleading measure of the compression force. Application of SG-HCS in osteoporotic bone without pre-drilling can slightly increase the compression force.

Falls are a common mechanism of injury in the older population, putting an increasing demand on scarce healthcare resources. The objective of this study was to determine healthcare costs due to falls in the older population. ⋯ Fall-related injuries are leading to a high healthcare consumption and related healthcare costs, which increases with age. Programmes to prevent falls and fractures should be further implemented in order to reduce costs due to falls in the older population and to avoid that healthcare systems become overburdened.

The ulnar coronoid process plays a central role in elbow stability due to its unique anatomic characteristics. A fracture of the coronoid, although uncommon, represents a serious injury that can adversely affect functional outcome if not treated appropriately. ⋯ A review of the literature was performed in order to evaluate different treatment strategies applied to clearly defined fracture configurations. 14 articles reporting data for the management of 236 coronoid fractures met our inclusion criteria and were subjected to critical analysis. The data suggest that recognition of specific coronoid fracture patterns, use of appropriate classification systems and application of staged surgical protocols can stabilise the elbow effectively and lead to favourable outcomes.
