Brief Description: This study compares the new Less Invasive Stabilization System (LISS) to the standard plates used for fracture fixation in the distal femur. The standard plates are the dynamic condylar screw in Type A, B, and C fractures, where possible and the condylar buttress plate in Type C fractures with coronal splits when a fixed angled device is not possible. The purpose of the study is to determine whether the rate of fracture healing and fracture union with the LISS device will be as good as or better than the usual fracture fixation systems.

Title of Study: A Prospective Randomized Multicentre Clinical Trail Comparing Open Reduction Internal Fixation with Primary Subtalar Fusion in Patients with Severely Comminuted (Sanders IV) Displaced, Intra-articular Fractures of the Calcaneus

Brief Description: Displaced, Sanders IV fractures with at least three fracture lines across the posterior subtalar facet usually result from high energy injury and have done poorly with both non operative and operative management. Nearly 50% of these patients go on to have fusion of the subtalar joint due to severe subtalar pain from the development of osteoarthritis. Eligible patients with Sander IV calcaneal fractures will be randomized to undergo ORIF or primary fusion as their first option. All patients will be followed for two years with assessments performed at five points.

Title of Study: Multicenter Prospective Randomized Transfusion Therapy Trial For Functional Outcomes in Cardiovascular Patients Undergoing Surgical Hip Fracture Repair

Brief Description: The overall goal is to determine whether a more aggressive transfusion strategy in patients with cardiovascular disease undergoing surgery for repair of hip fracture is associated with improved functional recovery and decreased risk of adverse postoperative outcomes. Patients will be randomized into one of tow transfusion groups in a three day post op window: patients assigned to the 10g/dL arm will receive enough blood to maintain their blood count at or above 10g/dL, patients assigned to the symptomatic arm will receive a blood transfusion only if their blood count falls below 8g/dL. Follow-up @ 30 and 60 days with in-hospital Troponin levels (not for treatment) to be batched to the core lab and standard in-hospital ECG and Hbb levels to be recorded.

Title of Study: The Effect of Teriparatide on Distal Radius Fractures Healing: A randomized, double-blinded multicenter trail.

Brief Description: Forteo® (Teriparatide), the human parathyroid hormone fragment PTH (1-34) is an anabolic agent that induces bone formation by activating osteoblasts and promoting differentiation of precursors into osteoblasts. It is the first bone forming agent that has been approved for the treatment of postmenopausal women with osteoporosis by increasing bone mineral density and decreasing fracture risk. Animal studies suggest that teriparatide may increase osseous integration and enhance mineralization of newly formed bone matrix as well as accelerate fracture healing by increasing callous formation and mechanical strength. This six moth study is a Phase 2 prospective, randomized, parallel, double-blind, placebo-controlled, multi-centered, multi-national, study. It will evaluate the effect of teriparatide on fracture healing in postmenopausal women who have sustained a unilateral, dorsally angulated, distal radius fracture. "The primary objective will be to determine whether teriparatide, at a dose approved for treatment of osteoporosis, enhances the rate of distal radius fracture healing as evidenced by both radiographic changes (plain film and CT) and functional outcome scores. Given the known anabolic properties of low-dose intermittent parathyroid hormone in human subjects and the intriguing data on fracture healing at higher doses of parathyroid hormone in animals, we hypothesize that patients receiving teriparatide after distal radius fractures will show significantly improved rates of fracture healing both radiographically and functionally. We also expect to see significantly fewer orthopedic complications such as delayed union, or nonunion in those receiving teriparatide. Teriparatide induced fracture healing has the potential to reduce the time for injured patients to return to normal functioning and reduce the overall costs of fracture care.

Title of Study: The Effects of Early Active Motion Rehabilitation after Teno Fix Tendon Repair in Zone II Flexor Tendon Lacerations of the Hand

Brief Description: Flexor tendon injuries of the hand represent a challenge for even the most experienced hand surgeon. The tendons of the hand are divided into anatomically and biomechanically complex area. The standard of care is to allow tendon healing prior to passive motion rehabilitation with mobilization being the key to preventing adhesions and achieving maximum range of motion post-operatively. However, if mobilization is performed too early in the presence of a weak tendon repair, there is risk of rupture. The Teno Fix tendon repair system, designed specifically to address these difficulties, offers a stronger and more stable tendon repair construct. This allows for early mobilization and we propose this study to evaluate the advantages of an early active motion rehabilitation program after tendon repair with the Teno Fix system. Our hypothesis is that early active motion rehabilitation will lead to a better range of motion of the affected finger while maintaining a low rupture rate. Patients with Zone II flexor tendon lacerations repaired with the Teno Fix device will undergo an early active motion protocol developed at the New York Orthopaedic Hospital, as tolerated by patients, starting post-op day 3. Each patient will be followed and our analysis will focus on range of motion, strength, pain, swelling, and functional outcome assessment with a limb specific questionnaire called the DASH (Disabilities of the Arm, Shoulder, and Hand).

Title of Study: Displaced Intra-articular Sanders IV Calcaneal Fractures - ORIF versus Fusion - A Prospective Randomized Trial

Brief Description: This is a prospective randomized trial that deals with the worst displaced intra-articular calcaneal fractures. Patients will be randomized into operative versus fusion groups with 2-year follow-up. They will initially be assessed with CT scans. They will have intra-operative reconstruction of the hind foot, or intra-operative reconstruction of the hind foot with denuding of the cartilage services and fusion. They will have 8 weeks of non-weight bearing with regular follow up with standardized calcaneal surgeon manning the site.

Number of sites: As many as possible, in Canada only, with an experienced calcaneal surgeon manning the site.
