Filter by:The purpose of this study is to determine the clinical efficacy of a novel sustained dynamic compression intramedullary nail for tibiotalocalcaneal (TTC) arthrodesis utilizing longitudinal weight-bearing computed tomographic imaging. Of particular focus will be assessment of compressive element recovery and its relation to fusion development over time and weight-bearing status. Additionally, the study will incorporate longitudinal fusion assessment to evaluate differences between three-dimensional weight-bearing computed tomography (WBCT) scans and two-dimensional radiographs (X-rays) at multiple points of the fusion process. Finally, the study will evaluate the differences in WBCT-based fusion assessment between automated and manual methodologies for fusion area calculation.

To evaluate the fusion status of the hindfoot bones after receiving the ViviGen graft, an FDA approved cellular bone matrix. This is used in a population indicated for hindfoot arthrodesis as an alternative to an autograft.
Osteochondral lesion of talus (OLT), osteoarthrosis and impingement/instability syndrome are most common ankle joint pathologies. This study analyses outcome after various different operative treatment of aforementioned pathologies. Investigators hypothesis is that patient characteristics, type of lesion and surgical technique affect the result of treatment. The investigators will compare subjective (questionnaire) and objective (clinical examination) status of patient before and after operation.
Evaluation of joint preserving procedure for asymmetrical ankle arthritis regarding the improvement of alignment and its effect on symptoms
Reconstructive foot and ankle surgery is performed under general anesthesia. Included in this spectrum of surgery are ankle arthroplasties, various fusions, corrective arthrodesis, and more. Pain control for after the surgery can be achieved purely with intravenous and oral pain medication or in combination with freezing of the nerves. Nerve freezing (nerve block) placed before surgery has the potential to substantially reduce the amount of inhaled anesthetic given to the patient during surgery. This can benefit the patient with being more awake and crisp more quickly after surgery. It can also reduce cost to the system. A further benefit which has received very little attention so far, is that reducing the amount of inhaled anesthetic given also lowers the environmental footprint created by the anesthetic. For the region of the foot and ankle to be fully frozen, both the sciatic nerve and the saphenous nerve must be successfully blocked. Sciatic nerve blockade is most commonly achieved by blocking the nerve in the popliteal fossa. This block is named popliteal nerve block. The investigators will examine and quantify the amount of inhaled anesthetic used for each case and will compare how the consumption is affected by whether the nerve blocks are applied before or after surgery. Patients will have two nerve block catheters (popliteal and saphenous catheter) placed under ultrasound-guidance prior to the case by an experienced and specifically trained anesthesiologist. The catheters will be loaded with a solution to which the anesthesiologist is blinded. It will either be local anesthetic or 5% dextrose (sham). The general anesthetic will be conducted according to a research protocol with anesthetic depth being the targeted endpoint. Measurements of the required MAC-Value (minimum alveolar concentration) of inhaled anesthetic will be recorded every five minutes by a study team member. At the end of the case the anesthesiologist will be unblinded to the solution. Should the patient have received sham initially, they will now receive the full dose of local anesthetic prior to being woken up.
Over the last decades, total ankle replacement (TAR) emerged as a reliable treatment option in end-stage ankle osteoarthritis (OA) while preserving motion and physiological load. The Cadence™ is a fourth-generation, two-component, fixed-bearing implant with minimal tibial and talar resection. It has been in clinical use since July 2016, the purpose of this study was to compare the clinical outcome and radiological outcomes of total ankle arthroplasty with use of the Cadence™ prosthesis at St. Michael's Hospital.
