compression device new Nitinol memory shape
staple looks like one
but it has compression properties
humerus - clavicle - distal radius  -
temporary reduction of IT fracture


  1. nickel titanium naval ordinance lab = nitinol 
  2. "proprietary heat treatment process sets the austenite transition temperature just below body temperature."

  3. is there nickle allergy ?
    1. is there problem of two metals interacting ?



PRODUCT OVERVIEW




  1. The ProFx table is specifically designed to enhance reduction and fixation of acetabular and pelvic fractures. Surgical reduction of these injuries remains a formidable challenge. Benefits of the table can be an easier reduction, making closed reduction possible, making open reduction possible through a lesser approach, and making the most difficult reductions possible at all. The narrow contact area the table makes with the pelvic area also enhances access.
  2. For acetabular fractures, the patient is positioned prone for the Kocher-Langenbeck, supine for the ilioinguinal, and lateral for the Extended Iliofemoral Approaches. The table and specific positioning enhances surgical exposure, aids reduction and helps protect the sciatic nerve from stretch injury. The capabilities of the KL and II approaches are maximized and the necessity to utilize 2 approaches or the EIF is minimized.
  3. For pelvic fractures, the table enhances exposure, and aids reduction. The most difficult fracture types are associated with a cranial (vertical) migration of the hemi pelvis. Distal traction applied with the table can be very effective in correcting cranial displacement. 
    1.  However, anterior ring injuries (ramus fracture, symphysis dislocation) can be further displaced if the table perineal post is used as counter traction. 
    2.  Table-skeletal fixation to the uninjured side provides the necessary stabilizer (counter traction) against the opposite injured side traction without the disadvantage of the perineal post. 
    3.  If the injury is easily reduced, the counter traction of the patient’s weight may be adequate with the table positioned in maximum trendelenberg.
    4. problem of perineal post 
      1. pin in sub -trochanter and pin in posterior spine anchored to table

They collected 30,000 30-second clips from patients with different forms of arrhythmia. To assess the accuracy of their algorithm, the team compared its performance to that of five different cardiologists on 300 undiagnosed clips. They had a panel of three expert cardiologists provide a ground-truth judgment. irhythm ecg  https://www.irhythmtech.com/products-services/zio-xt Uninterrupted, comprehensive monitoring and easy EKG interpretation helps you find answers in a single test and provide superior clinical service to your patients. https://www.irhythmtech.com/products-services/zio-at PATIENT-FRIENDLY DESIGN MINIMIZES DISRUPTION AND MAXIMIZES COMPLIANCE Our comfortable, effortless monitoring experience drives 98% patient comp...

tibia nail low cost modified kuntscher daga solapur Dynamic osteosynthesis by modified Kuntscher nail for the treatment of tibial diaphyseal fractures  Wasudeo M Gadegone and Yogesh S Salphale Indian J Orthop . 2009 Apr-Jun; 43(2): 182–188. doi:  10.4103/0019-5413.48824 Twelve cases resulted in acceptable malalignment due to operative technical error.  Entry 60 % from medial side plateau and 20 mm posterior ot tibial tubercle  The bony anatomy of Asians differs from that of western populations in both size and morphology such as the coronal plane of proximal tibia is more varus and the angle between the anterior shaft of the tibia and the slope of the tibial plateau in the sagittal plane is higher in Asians [9,10]. These affect the accuracy of the entry point of tibial SIGN nail. https://www.hilarispublisher.com/open-access/accurate-entry-point-for-tibial-nailing-with-sign-nail-in-asians-a-cadaveric-study-2167-1222.1000135.pdf   end...
