Tibiotalar Arthrodesis: Development Of A Novel Jig And Alignment Guide, Adam Mathew Ropchan
Electronic Thesis and Dissertation Repository
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 ...

Collared Vs. Collarless Total Hip Arthroplasty In Both Direct Anterior And Direct Lateral Approach Surgery: A Prospective Cohort Comparison Study, 2018 The University of Western Ontario
Collared Vs. Collarless Total Hip Arthroplasty In Both Direct Anterior And Direct Lateral Approach Surgery: A Prospective Cohort Comparison Study, Seb Heaven
Electronic Thesis and Dissertation Repository
Total hip arthroplasty (THA) is one of the most successful surgical procedures performed worldwide. Recent advances in implant technology and popularization of the muscle-sparing Direct Anterior (DA) approach to the hip has led to younger patients becoming candidates for hip arthroplasty surgery. Among the many considerations necessary for success in this patient population, implant design plays an important role in determining outcomes.
In this thesis, we prospectively evaluated patients who received a collared or collarless fully hydroxyapatite-coated femoral stem during THA with a standard RSA protocol to assess stem migration patterns following surgery.
Preliminary results indicate that collarless stems subside ...

The Perioperative Patient Experience Of Hand And Wrist Surgical Patients: An Exploratory Study Using Patient Journey Mapping, Else F. De Ridder, Tessa Dekkers, Jarry T. Porsius, Gerald Kraan, Marijke Melles
Patient Experience Journal
Patient-centred care is becoming more important in healthcare. The success of patient-centred care can be assessed by exploring the patient experience through a patient journey map. As the number of outpatient surgeries is increasing, it is important to reveal the specific characteristics of this type of surgery. The perioperative patient experience is considered very important for outpatient surgery, because all perioperative activities are condensed in one day. To investigate this experience, we performed a case study of hand and wrist surgery. Six teams of two industrial design engineering students interviewed 40 patients in total in two private and two public ...
Direct Crystal Formation From Micronized Bone And Lactic Acid: The Writing On The Wall For Calcium-Containing Crystal Pathogenesis In Osteoarthritis?, Anna A. Bulysheva, Nardos Sori, Michael P. Francis
Pathological calcium-containing crystals accumulating in the joints, synovial fluid, and soft tissues are noted in most elderly patients, yet arthritic crystal formation remains idiopathic. Interestingly, elevated lactic acid and bone erosion are frequently among the comorbidities and clinical features of patients with highest incidence of crystal arthropathies. This work shows that bone particulates (modeling bone erosion) dissolve in lactic acid and directly generate crystals, possibly presenting a mechanism for crystal accumulation in osteoarthritis.
Methods and results
Micronized human bone (average particle size of 160 μm x 79 μm ) completely dissolved in lactic acid in 48 hours, and in synovial ...

The Impact Of Free Radical Stabilization Techniques On In Vivo Property Changes In Highly Cross-Linked Polyethylene Acetabular Liners, 2018 The University of Western Ontario
The Impact Of Free Radical Stabilization Techniques On In Vivo Property Changes In Highly Cross-Linked Polyethylene Acetabular Liners, Michael M. Decker .
Electronic Thesis and Dissertation Repository
Highly cross-linked polyethylene (HXLPE) was introduced into total hip arthroplasty (THA) to reduce long-term wear-related complications. However, HXLPE production and in vivo oxidation can alter mechanical behavior. Mechanical failure of HXLPE liners at the implant rim have been reported. The purpose of this thesis is to determine if thermal free radical stabilization techniques used in HXLPE production alter the mechanical properties, physical properties and oxidative stability of liner rims after extended in vivo time.
Retrieved remelted, single annealed and sequentially annealed HXLPE liner rims were mechanically tested using a validated microindentation technique. Oxidation and crystalline phase composition were measured. Results ...

Journal of Mind and Medical Sciences
Introduction. Reconstruction of heel soft tissue defects represents a true challenge for any surgeon due to the particularities of this anatomical region. The tissue used to reconstruct the heel area must be resistant, innervated, and adapted to take over the body weight. Innervated medial plantar fasciocutaneous flap is one of the best solutions to cover defects at the heel level.
Materials and Methods. We studied 5 patients, 4 males and one female, aged 42 to 67 years, who presented heel soft tissue defects of various etiologies. In all cases, the used reconstructive method was an insular innervated medial plantar fasciocutaneous ...

The Venus de Milo, an ancient Greek statue, has been viewed as one of the most celebrated pieces of art in Western culture. It was sculpted during the Hellenistic period between 150 and 50 BC and is believed to be the work of Alexandros of Antioch. The sculpture is thought to depict Aphrodite, the Greek goddess of love and beauty. When assembled, the two halves of the sculpture meet in an almost horizontal line that is purposefully obscured by a roll of garment around the hips. It has been noted that the midline of the statue's face is displaced ...

Orthopaedic Surgery and Sports Medicine Faculty Publications
Background. The majority of patients develop posttraumatic osteoarthritis within 15 years of anterior cruciate ligament (ACL) injury. Inflammatory and chondrodegenerative biomarkers have been associated with both pain and the progression of osteoarthritis; however, it remains unclear if preoperative biomarkers differ for patients with inferior postoperative outcomes. Hypothesis/Purpose. The purpose of this pilot study was to compare biomarkers collected on the day of ACL reconstruction between patients with "good" or "poor" 2-year postoperative outcomes. We hypothesized that inflammatory cytokines and chondrodegenerative biomarker concentrations would be significantly greater in patients with poorer outcomes. Study Design. Prospective cohort design. Methods. 22 patients ...
