Orthopaedic surgical treatments emphasizing immobilization using open reduction and internal fixation with osteosynthesis devices are widely accepted for their efficacy in treating complex fractures and reducing permanent musculoskeletal deformity. However, such treatments are profoundly underutilized in low- and middle-income countries (LMIC), partially due to inadequate availability of the costly osteosynthesis devices. Orthopaedic surgeons in some LMIC regularly re-use osteosynthesis devices in an effort to meet treatment demands, even though such devices typically are regulated for single-use only. The purpose of this study is to report a reprocessing protocol applied to explanted osteosynthesis devices obtained at a leading trauma care hospital. ⋯ This study was motivated by the treatment demands encountered by orthopaedic surgeons providing medical treatment in several different LMIC and their need for access to basic osteosynthesis devices. The rigorous decontamination protocol and generalized inspection criteria proved useful for efficiently screening a large volume of devices. Given that re-used osteosynthesis devices can yield satisfactory results, this study addresses potential complications of re-used devices and valid concerns that relate to patient safety. Implementing this defined reprocessing protocol into existing re-use practises in LMIC helps to limit the risks of inadequate sterilization and structural failure without adding additional risks to patients receiving re-used devices.

In 1981, Moore introduced a new classification for dislocation-type fractures caused by high-energy mechanisms. The most common medial Moore-type fractures are entire condyle fractures with the avulsion of the median eminence (tibial anterior cruciate ligament (ACL) insertion). They are usually associated with a posterolateral depression of the tibial plateau and an injury of the lateral menisco-tibial capsule. This uniform injury of the knee is increasingly observed in the recent years after skiing injuries due to the high-speed carving technique. This uprising technique uses shorter skis with more sidecut allowing much higher curve speeds and increases the forces on the knee joint. The aim of this study was to describe the injury pattern, our developed operative approach for reconstruction and outcome. ⋯ In our view, it is crucial to recognise the different components of the injury in the typical postero-medial fracture dislocation of the proximal tibia. The described larger medial approach for this type of medial fracture dislocation allows repairing most of the injured aspects of the tibial head, namely the medial condyle with postero-medial buttressing, the distal insertion of the ACL and the posterolateral impaction of the plateau.

Paediatric pelvic fractures have been infrequently reviewed. The study was performed to highlight the unique features of pelvic fractures in children. ⋯ Paediatric pelvic fractures differ from their adult counterpart in aetiology, fracture type, and associated injury pattern. They represent a reliable marker for severe trauma. Prospective studies are required to define optimal treatment guidelines, particularly in older children.

To establish whether the modified anatomic plate (MAP) performs as well as the anatomic plate (AP), dynamic hip screw (DHS) and proximal femoral nail (PFN) from a biomechanical perspective. ⋯ The biomechanical features of the MAP were similar to those of the PFN. The MAP generated optimal loads at both the fracture site and the proximal femur. FE methods and biomechanical tests revealed that the MAP is associated with both intra- and extra-medullary fixation features, even though the load was applied as an extramedullary stimulus.

Comparative Study
Are there any advantages in using a distal aiming device for tibial nailing? Comparing the Centro Nailing System with the Unreamed Tibia Nail.
The distal locking of an intramedullary tibial nail can be challenging and time consuming when performed freehand. This study was conducted to evaluate if a distal aiming device would reduce surgical time. ⋯ The use of an aiming device for distal locking of a tibia nail lengthens operation time rather than reducing it. Fluoroscopy was still needed in about half of the cases. No difference was seen in clinical outcomes. The use of a distal aiming device to lock a tibial nail appears to have no benefit.
