Randomized Controlled Trial Multicenter Study
Micromotion in the fracture healing of closed distal metaphyseal tibial fractures: A multicentre prospective study.
The dynamic locking screw (DLS) in association with minimally invasive plate osteosynthesis (MIPO) in a bridging construct for simple metadiaphyseal long bone fractures enables modulation of the rigidity of the system and facilitates the development of early and triplanar bone callus. Twenty patients affected by distal tibial fracture were treated with MIPO bridging technique and DLS at the proximal side of the fracture. Time of consolidation, quality of the reduction, complications and American Orthopaedic Foot and Ankle Society (AOFAS) score were monitored and the results compared with those from a control group treated with only standard screws on both fracture sides. ⋯ Performance was considered significant for p<0.05. The mean healing time was 17.6 ± 2.8 weeks in the group treated with standard screws and 13.5 ± 1.8 weeks in the group treated with DLS (t=5.5, p<0.0001). The DLS was associated with early healing and triplanar bone callus.

Multicenter Study
Heel displaced intra-articular fractures treated with mini-calcaneal external fixator.
Treatment of displaced heel fractures is controversial; however, ORIF is widely described in the literature to be the gold-standard. Percutaneous reduction and monolateral external fixation is gaining increasing attention because it provides a good and stable reduction, and minimises soft tissue complications due to open surgery, such as deep infections and delays in wound healing. The aim of this study was to show that the new Orthofix Calcaneal Minifixator (six pins) provides a greater stability than the four-pin version to enable a better and more stable reduction, an earlier weight-bearing (30 days) and improved functional outcomes. ⋯ The excellent functional outcomes were despite some radiological images of imperfect posterior facet anatomical reduction and seemed to correlate with the use of a good and stable minimally-invasive surgical technique. This technique enabled early weight-bearing, minimised complications, respected the delicate biology of this anatomical site and restored the good heel volume and Böhler angle.
