    The female geriatric proximal humeral fracture: protagonist for straight antegrade nailing?
    Arch Orthop Trauma Surg 2017 Jul 29. Epub 2017 Jul 29.
    Department of Trauma Surgery, Medical University Innsbruck, Anichstr. 35, 6020, Innsbruck, Austria.
    Introduction: Straight antegrade humeral nailing (SAHN) has become a standard technique for the surgical fixation of proximal humeral fractures, which predominantly affect elderly females. The nail's proximal anchoring point has been demonstrated to be critical to ensure reliable fixation in osteoporotic bone and to prevent iatrogenic damage to the superior rotator cuff bony insertion. Anatomical variations of the proximal humerus, however, may preclude satisfactory anchoring of the nail's proximal end and may bare the risk of rotator cuff violation, even though the nail is inserted as recommended.

    Introduction: Although it is well known from cadaveric and biomechanical studies that transtibial femoral tunnel (TT) positioning techniques are associated with non-anatomic tunnel positions, controversial data exist as so far no clinical differences could have been found, comparing transtibial with anteromedial techniques (AM). The purpose of the study was to analyze if graft failure following TT ACL reconstruction was more commonly associated with non-anatomic tunnel position in comparison with the AM technique. We hypothesized that, compared to AM techniques, non-anatomic tunnel positions correlate with TT tunnel positioning techniques. Read More

    Introduction: External fixation can be performed in poor bone and soft tissue conditions, and can be used in patients with poor general conditions or multiple injuries as a rapid, mini-invasive procedure. The purpose of the current study was to evaluate the effectiveness and safety of the Ilizarov external fixator in the management of proximal humeral fractures.

    Materials And Methods: Between May 2011 and December 2013, 14 patients with displaced proximal humeral fractures were enrolled in the current study. Read More

    Introduction: To observe changes of spinopelvic parameters and the presence of pelvic incidence (PI) variation in different positions, and the accuracy of PI compared with CT scan.

    Materials And Methods: Patients with standing whole-spine radiograph, CT scan of the pelvic bone, and MRI of the lumbar spine done within a few days were included. The pelvic [pelvic tilt (PT), sacral slope (SS), and PI] and spinal [lumbar lordosis (LL)] parameters were measured by two different observers. Read More

    Comparison of lateral and skyline fluoroscopic views for detection of prominent screws in distal radius fractures plating: results of an ultrasonographic study.

    Introduction: Extensor tendon rupture is a recognized complication of volar plate fixation of distal radius fractures due to screws protruding past the dorsal cortex. The aim of this study was to compare the Skyline view with traditional lateral fluoroscopic views using ultrasonography as a reference standard in the postoperative assessment.

    Materials And Methods: A monocentric prospective study was conducted to identify screws penetrating the dorsal cortex after volar plating of distal radius fractures. Read More

    Posterior locked lateral compression injury of the pelvis in geriatric patients: an infrequent and specific variant of the fragility fracture of pelvis.

    Department of Orthopedic Surgery, College of Medicine, Daejeon St. Mary's Hospital, The Catholic University of Korea, Daeheung-ro 64, Jung-gu, Daejeon, 34943, Republic of Korea.
    Introduction: Posterior locked lateral compression injury (PLLCI) of the pelvic ring is an infrequent variant of lateral compression injury, a condition described in only eight reported cases since 2000. Lateral compression injury usually results from high-energy trauma and is characterized by locking between the medially translated fractured ilium and the anterior border of the sacrum, regardless of whether the fractured ilium involves the sacroiliac joint. However, in our experience, lateral compression injury can also result from low-energy trauma as a manifestation of pelvic fragility fracture. Read More
