Prosthelast - Distal Radius Hemiarthroplasty Prosthesis
Admin
All that Hemiarthroplast-ies are not at the hip…
We always have an implant for everything. But one of the difficulties we face is holding the implant in place in a porotic bone. Especially in distal radius fractures which is the most common upper limb fracture, when the bone is porotic holding the implant in place is a struggle. Be it an LCP or a wire.
We end up immobilising it longer than usual where Early mobilisation is key. Prosthelast TM might have an answer at least in specific use cases. It is a Distal radius Hemiarthroplasty prosthesis indicated for comminuted injuries where osteosynthesis was not deemed to be a good option.
Prosthelast also has a carpal component which gives a metal on poly articular surfaces. This Implant is claimed to be built on the learning points of the previous failed ones. The centromedullary wire helps in redistributing the forces along the Radius.
In an interesting case study, it was used following resection of malignant tumour distal radius. Mind that longer term studies and RCTs will be needed to properly evaluate this implant but it’s good to have as a part of our metal inventory.
