Filter by:The purpose of this study is to compare two different antibiotic regimens and techniques during total ankle arthroplasty (TAA). Primary Objective: Comparable levels of vancomycin will be found in bone, soft tissue, and systemic samples between patient groups. Secondary Objective: Compare 30 day and 90 day post-operative complication rates (infection) between the control (standard IV administration of vancomycin) vs the interventional group (intraosseous administration of vancomycin). The investigators hypothesize that there will be no difference in complication (infection) rates between groups.
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.

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.

Ankle arthritis is associated with debilitating pain and chronic disability. For the treatment of severe ankle arthritis, total ankle arthroplasty (TAA) is one treatment option. Postoperative pain management in joint arthroplasty is an ongoing and relevant issue. The purpose of this study is to examine if differences exist in postoperative pain control, overall patient satisfaction, and use of narcotics using an intra-articular injection in the operating room compared with a peripheral nerve block in patients undergoing TAA.
This retrospective and prospective study intends to evaluate the epidemiology and effectiveness of ankle joint surgery in patients operated from January 2011 to March 2026, evaluating the results both clinically and radiographically.
Surgical options for managing hindfoot arthritis include: joint fusion, total ankle joint replacement or osteotomies (realignment) of bones. Fusion of arthritic hindfoot joints has been the accepted method of managing hindfoot arthritis for over a century. Recently, total ankle replacement has evolved as a treatment option for patients with end stage ankle arthritis. A comparison of gait for patients before and after hindfoot fusion or total ankle replacement will give further information about the outcome of this treatment. The principal aim of this project is to assess the effect of total ankle replacement or hindfoot fusion on gait. We are also interested in the outcome of the surgery and its effect on your symptoms (eg. pain and mobility). The results of this study will aid researchers in assessing this new treatment modality. Your involvement in this study is critical for the researchers to further analyze this new form of treatment and your time and involvement is appreciated.
