Calcaneal Tuberosity Fracture With Complete Achilles Tendon Rupture: A Unique Surgical Challenge.

A calcaneal tuberosity avulsion fracture occurring simultaneously with a rupture of the Achilles tendon, although occurring through similar mechanisms, is a rare injury pattern to see in combination and presents a unique challenge to the surgeon. The patient we present was initially found to have a type II fracture of the calcaneal tuberosity. However, during surgical fixation of the fracture, a complete rupture of the Achilles tendon was noticed. The technique used in this case was the fixation of the fracture fragment with two 5 mm fully threaded screws. The tendon was then reattached to the calcaneus using two Mitek anchors (DePuy Mitek Inc., MA, USA) with a modified Bunnell technique. There are a number of techniques suggested in the literature, including, among others, K-wires (DePuy Mitek Inc., MA, USA) and screw fixation. Our patient recovered well and has now been discharged from further orthopaedic follow-up.

Incorporating uncertainty in Indigenous sea Country monitoring with Bayesian statistics: Towards more informed decision-making.

Partnerships in marine monitoring combining Traditional Ecological Knowledge and western science are developing globally to improve our understanding of temporal changes in ecological communities that better inform coastal management practices. A fuller communication between scientists and Indigenous partners about the limitations of monitoring results to identify change is essential to the impact of monitoring datasets on decision-making. Here we present a 5-year co-developed case study from a fish monitoring partnership in northwest Australia showing how uncertainty estimated by Bayesian models can be incorporated into monitoring management indicators. Our simulation approach revealed there was high uncertainty in detecting immediate change over the following monitoring year when translated to health performance indicators. Incorporating credibility estimates into health assessments added substantial information to monitoring trends, provided a deeper understanding of monitoring limitations and highlighted the importance of carefully selecting the way we evaluate management performance indicators.
