Local bone quality measure and construct failure prediction: a biomechanical study on distal femur fractures.
The aim of this investigation was to better understand the differences in local bone quality at the distal femur and their correlation with biomechanical construct failure, with the intention to identify regions of importance to optimize implant anchorage. ⋯ The local bone quality at the distal femur indicates that in plated distal femur fractures the distal posterior screw holes seem to be the key ones and should be occupied. Measurement of the local bone strength with DensiProbe™ is one possibility to determine the risk of construct failure, therefore, thresholds need to be defined.

Additional coracoclavicular augmentation reduces revision rates in the treatment of lateral clavicle fractures as compared to angle-stable plate osteosynthesis alone.
There is no uniform approach to the management of lateral clavicle fractures. Recent studies have investigated additive coracoclavicular (CC) augmentation as a treatment option; however, it is unclear whether it is superior to conventional locking plate osteosynthesis. ⋯ Additive CC augmentation in combination with locking plate osteosynthesis seems to improve the vertical stability and reduces the revision rate in patients with a lateral clavicle fracture. Furthermore, an arthroscopy-assisted procedure allows for an intraoperative detection and single-step treatment of accompanying intraarticular pathologies.

Results after spica cast immobilization following hip reconstruction in 95 cases: is there a need for alternative techniques?
Developmental dysplasia of the hip (DDH), neurogenic dysplasia of the hip (NDH), and Perthes disease often require surgical treatment. Spica casting is a common postoperative immobilization. The purpose of this study was to evaluate the complications related to the immobilization. ⋯ Evidence level level IV, case series.

Similar biomechanical properties of four tripled tendon graft models for ACL reconstruction.
The present study tested and compared the biomechanical properties of four different triplicate graft tendon techniques. ⋯ This study reported similar biomechanical behavior of four different models of tripled grafts suitable for ACL reconstruction. In addition, the biomechanics of overall tripled tendon grafts seems more affected by the viscoelastic property of the tendon itself rather than the preparation method.
