1. Gammon, Braden M. Arthrokinematics of the Distal Radioulnar Joint in the Normal Wrist and Following Distal Radius Malunion.

Degree: 2016, University of Western Ontario

Contact patterns in the distal radioulnar joint (DRUJ) are not well understood for normal anatomy or with distal radius deformity. This thesis presents three studies which investigate the arthrokinematics of the DRUJ for these conditions. The first study compared casting and Tekscan, two standard methods for contact measurement, with a novel technique of proximity mapping termed Inter-cartilage Distance (ICD). The relative benefits, limitations and role for ICD in DRUJ contact assessment were examined and discussed. The second study used ICD to characterize contact patterns in the native DRUJ. Contact was found to be maximal in 10 degrees of supination and the contact centroid moved volar and proximal with supination. The third and final study evaluated the effect of dorsal angulation deformity on DRUJ arthrokinematics. The contact centroid moved volarly, while simulated TFCC rupture reduced DRUJ contact area and caused the centroid position to become more variable in its pathway.

2. Ropchan, Adam Mathew. Tibiotalar arthrodesis: development of a novel jig and alignment guide.

Degree: 2018, University of Western Ontario

Tibiotalar arthrodesis is a surgical procedure, used for the treatment of end-stage ankle arthrosis and instability. There are dozens of described procedures in the literature, all with varying rates of success. Two of the most common reasons for reoperation in tibiotalar arthrodesis are nonunion and infection; few studies have established any associations between patient/surgical factors and reoperation for nonunion and infection. The first part of this thesis focuses on determining the rate of reoperation to the ipsilateral lower limb and if any patient/surgical factors are associated with reoperation for nonunion and infection. The second part of this thesis turns attention to developing a jig and alignment guide to improve outcomes, and to standardize this procedure. The rationale for developing the jig and alignment guide is based on the success of such devices in improving the outcomes in total hip and knee arthroplasty.

3. Abramo, Antonio. Fracture of the distal radius - outcome, primary surgery and treatment of malunion.

Degree: 2008, University of Lund

A consensus protocol for treatment of distal radius fractures (DRF) has been developed to aid clinicians in treatment decision making. The protocol was evaluated in Paper I using a validated subjective outcome instrument, DASH in 518 consecutive patients. A good final subjective result was achieved with the proposed protocol, regardless of initial severity with a low median DASH score in all groups at final follow up 1 year after the fracture. No differences were seen for the various operative techniques. In Paper II, 50 patients with an unstable or complex DRF were randomized to either closed reduction and external fixation, or open reduction and internal fixation using the TriMed® system. Pronation/supination and grip strength were better in the internal fixation group at one year compared to the external fixation group. There were no differences in DASH scores or in radiographic parameters. In Paper III we investigated function in patients following an osteotomy due to a malunion after a DRF. Instead of autologous iliac crest bone graft we used a slow resorbing bone substitute (Norian SRS®), consisting of hydroxyapatite, to fill the gap in combination with the TriMed system for fixation. We were able to improve forearm rotation, flexion/extension and radioulnar deviation from. Grip strength increased and DASH scores decreased substantially. The achieved radiographic correction was consistent over the first year but the resorption was slow and the time to remodel was long. In Paper IV a novel bone substitute (Cerament®) was used with a faster resorbing mixture of calcium phosphate and calcium sulphate. 15 consecutive patients with a radiographic and clinically manifesting malunion after a DRF underwent an osteotomy. The same technique was used for fixation of the osteotomy as in Paper III but this time with Cerament® as bone substitute. Grip strength increased and DASH scores decreased. A fast remodelling of the bone was noticed but also an increase of ulnar variance from immediately postoperatively to final follow up. Using a bone substitute, the operation can be performed as an outpatient procedure and donor site pain avoided. Osteotomy of the distal radius is an effective treatment for malunited distal radius fractures, but perhaps a more rigid fixation is needed in fast remodelling bone substitutes.
