  • Radio-Luno-Triquetral Bone-Ligament Transfer As an Additional Stabilizer
    Archives of Orthopaedic and Trauma Surgery https://doi.org/10.1007/s00402-020-03690-2 HANDSURGERY Radio‑luno‑triquetral bone‑ligament transfer as an additional stabilizer in scapholunate‑instability Luzian C. P. Haug1 · Tom Adler1 · Dietmar Bignion1 · Esther Voegelin1 Received: 23 April 2020 / Accepted: 11 November 2020 © The Author(s) 2020 Abstract Introduction Reconstruction of the scapho-lunate (SL) ligament is still challenging. Many diferent techniques, such as capsulodesis, tendon graft and bone-ligament-bone graft have been described to stabilize reducible SL dissociation. If primary ligament repair alone is not possible, an additional stabilizer is needed to achieve scapho-lunate stability. A new local bone-ligament transfer using half of the radio-luno-triquetral ligament is performed. The direction of traction of the transposed ligament is very similar to the original ligament. Ideal tension can be attained by fxation of the bone block at the dorsal ridge of the scaphoid. The biomechanical stability of this bone-ligament transfer shall be examined biomechanically. Material and methods Computed tomography imaging was performed using eight cadaveric forearms with a defned posi- tion of the wrist. Axial load was accomplished with tension springs attached to the extensor and fexor tendons. Three series ([a] native, [b] divided SL ligament and [c]) after reconstruction with bone-ligament transfer] were reconstructed three- dimensionally to determine the angles between radius, scaphoid and lunate. The radial distal part including a bone fragment of the radio-luno-triquetral ligament was transferred from its insertion at the distal edge of the radius to be attached to the dorsal ridge of the scaphoid.

Abstract Background The aim of this study is to evaluate the clinical and radiological midterm results of a combined dorsal tenodesis–capsulodesis for static and reducible scapho- lunate dissociation (SLD). Patients and Methods We evaluated 20 of 22 consecutive patients with static SLD minimum with follow-up of 2 years operated between 2003 and 2012. The mean age was 40 years (range: 23–65 years). Seventeen were men. Final evaluation included comparative wrist range of motion (ROM) and grip strength, pre- and postoperative pain and function by visual analog scale, and QuickDASH and Wrightington scores. Radio- graphs included preoperative, early postoperative, and final X-rays. Scapholunate space (SLS) and scapholunate and radioscaphoid angles (SLA and RSA) were measured. Statistical significance was evaluated with Student t-test, considered significant when p < 0.05. Results Mean follow-up was 67 months (range: 24–126 months). Mean final ROM was: flexion 55 degrees (73%), extension 62 degrees (90%), radial deviation 19 degrees (82%), and ulnar deviation 44 degrees (90%).

At the scene, she had experienced immediate severe knee pain and was unable to bear weight. Anteroposterior radiographs of the knee revealed a minimally displaced fracture to the lateral femoral condyle (Image 1). Computed tomography (CT) revealed injury of the distal femoral epiphyseal growth plate (Salter- Harris type 4), and the point near the epiphyseal closing was tender in the patient (Image 2). Three-dimensional CTs are useful in delineating the coronal shear component (Image 3). Knee arthroscopy revealed severe complications including posterior cruciate ligament ruptures, medial collateral ligament injury, and Image 1.

Abstract ID: Paper 001 *Chelsea S. Mathews, M.D. / Little Rock, AR Karan D. Dua, M.D. / Baltimore, MD Austin A. Cole / Little Rock, AR Eric R. Siegel, M.S. / Little Rock, AR Joshua M. Abzug, M.D. / Baltimore, MD Theresa O. Wyrick, M.D. / Little Rock, AR INTRODUCTION: Ulnar artery thrombosis (UAT), or hypothenar hammer syndrome, has strong correlations with individuals involved in manual labor and various athletic professions. Activities that produce a persistent impact on the hypothenar eminence can damage blood vessels of the hand, specifically the ulnar artery as it passes through Guyon’s canal. To our knowledge, the prevalence of these symptoms residing in orthopedic surgeons is unknown. We hypothesized that orthopedic surgeons would have an increased prevalence of UAT than the general population and that this would be true of surgeons who perform a large volume of hip and knee arthroplasty due to frequent use of oscillating saws and methods of retractor placement. METHODS: 80 current, retired, and resident orthopedic surgeons at two separate institutions were surveyed for symptoms of ulnar artery thrombosis (UAT). Participants completed surveys indicating symptoms of UAT and participation in leisurely activities that may also increase their risk. A timed Allen’s test was performed with the radial artery occluded and the time to reperfusion of the hand was measured.

No statement or presentation made is to be regarded as dedicated to the public domain. Precourse 12: Athletic Injuries of the Upper Extremity: The Adolescent to the Adult - The Amateur to the Professional The treatment of the injured athlete remains a continued challenge. The skeletally immature, the weekend warrior, the high-level amateur and the professional athlete all pose specific difficulties for the hand surgeon in treating the injury. Ultimately, however, the surgeon is nearly always faced with the goal of early return to play with minimal risk. This goal must be balanced with the chance of re-injury and lasting damage to the patient. The purpose of this pre-course is to offer an up-to-date review of hand, wrist and forearm injuries in the athlete, emphasizing pertinent anatomy, mechanism of injury, conservative and operative treatment and safe return to play. Lectures given by noted faculty will be divided into anatomic modules with attention to bone, ligament, tendon and miscellaneous topics. Case presentations will initiate each talk followed by a concise presentation on the specific topic emphasizing potential differences between the adolescent and the adult and the amateur versus the pro.
