Joint Sparing Implants
During our long history in orthopaedic implants it has always been our aim to save the joint if it is at all possible.
We now have considerable experience in specific techniques, enabling surgeons to consider wider operative possibilities for patients.
With advances in CT imaging and computerised 3D modelling, our designers are able to create accurate bone models and then incorporate anatomically shaped prostheses using intracortical and extracortical plates to retain the remnant of a joint. Early concerns relating to blood supply to the joint were soon dispelled as bone remnants remained vital and indeed continued to grow in children. Patients are able to rapidly return to normal activities with an excellent range of joint motion.
Early results are extremely encouraging and demonstrate that is possible to obtain sound osseomechanical integration between a massive implant and the epiphyseal bone remnant following intra-epiphyseal resection of a high grade sarcoma. The oncologic results are as good as those obtained following conventional resection and reconstruction.
Joint sparing surgery is more demanding than conventional resection surgery and is leading us to advances in computer guided tumour resection and robot assisted tumour resection surgery.
